Improv: A Lit Review
Why a lit review?
Because I am writing content for a new venture!
In a few weeks, a good friend and colleague and I are going to be offering improv-informed continuing education workshops. The workshops will be for anyone who works with clients or patients and would like to be more attuned, be good with a pivot and generally live outside the box. April and I are both therapists, so we will probably skew that way, but the workshops will be open to anyone!
So, there I was, writing content for the Why Come to the Lab? section and I realized I wanted some hard evidence. I mean we want people to come to our workshops because improv is fun and we are very good at what we do, but also because improv interventions are evidence based (and deeply rooted in social work values, but that's another blog). The review also highlights how improv techniques can be used across a variety of professions and modalities.
For this version of the lit review I have edited out the Methodology, the Study Design Distribution, and the Recommendations sections to make for a shorter reading experience. If you would like to read those sections, I have included a link to the full text at the bottom of the page.
Improvisational Theater in Therapeutic Contexts: Literature Review
Shannon Hardy, MSW, RSW
Abstract
Improvisational theater techniques have emerged as an innovative therapeutic intervention across diverse clinical populations and settings. This literature review examined 30 peer-reviewed studies examining the application of improvisation-based approaches in mental health treatment, clinical training, and psychosocial rehabilitation. The review also examines theoretical frameworks underpinning improv-based interventions, therapeutic mechanisms, clinical outcomes across populations, and methodological quality of existing evidence. Key findings indicate that improvisational methods promote social reciprocity, emotional expression, tolerance of uncertainty, and narrative capacity in clinicians and patients. Reported outcomes include reduced anxiety, improved social cognition, enhanced group cohesion, decreased burnout, and high participant satisfaction. However, the evidence base consists predominantly of pilot studies, qualitative investigations, and small quasi-experimental designs. Large-scale randomized controlled trials with standardized outcome measures and long-term follow-up remain scarce. Theoretical frameworks emphasize present-centered spontaneity, safe fiction frames, co-creative learning, and action-based access for nonverbal populations. This review identifies significant methodological limitations and proposes future research directions to establish efficacy, clearer mechanisms of action, and develop evidence-based protocols for improv-based therapeutic interventions.

Introduction
Over the past two decades, clinicians and researchers have explored improvisational methods across diverse populations and clinical contexts, from autism spectrum disorder interventions to professional training programs for mental health practitioners. These applications draw upon drama therapy traditions while extending beyond formal drama therapy to include applied theater, therapeutic theater, and improvisation-informed clinical practice [4], [5], [6]. The appeal of improv-based interventions stems from their capacity to engage participants through embodied, action-oriented processes that reduce reliance on verbal-cognitive abilities, create safe spaces for emotional exploration through fictional frames, and foster social connection through collaborative creativity [7], [8], [9].
Despite growing clinical interest and promising preliminary findings, the evidence base for improvisational theater in therapeutic contexts remains fragmented and methodologically heterogeneous. Existing literature spans multiple disciplines, including psychology, psychiatry, education, social work, and performance studies, with varying terminologies, theoretical frameworks, and outcome measures. This comprehensive review synthesizes this relatively fragmented evidence, examining theoretical foundations, clinical outcomes across populations, methodological quality, and future research directions.
The primary objectives of this review are to: (1) identify and synthesize theoretical frameworks explaining therapeutic mechanisms of improvisational interventions; (2) systematically examine clinical outcomes across diverse populations and settings; (3) evaluate the quality and rigor of existing evidence; (4) identify methodological limitations and gaps in current research; and (5) propose evidence-based recommendations for future investigation and clinical practice. By consolidating findings from pilot studies, qualitative investigations, and emerging controlled trials, this review aims to provide a foundation for advancing the field of improv-based therapeutic interventions.
3. Theoretical Frameworks and Mechanisms of Action
Improvisational theater interventions draw upon multiple theoretical frameworks that explain their therapeutic mechanisms and clinical utility. This section highlights five primary theoretical perspectives identified across the reviewed literature, each emphasizing distinct psychological processes and pathways to therapeutic change.
3.1 Present-Centered Spontaneity and Therapeutic Presence
A central theoretical framework positions improvisation as a practice of present-moment awareness and spontaneous responsiveness. This perspective aligns with humanistic and existential therapeutic traditions that value immediacy, authenticity, and here-and-now engagement [3], [21], [22]. Improvisation requires participants to attend fully to emerging stimuli, such as verbal and nonverbal cues from scene partners, environmental changes, and internal impulses, without reliance on predetermined scripts or rehearsed responses.
This present-centered quality cultivates therapeutic presence, defined as the capacity to be fully attentive, emotionally available, and flexibly responsive in interpersonal encounters [19], [22]. For clinicians, improvisation training enhances the ability to track moment-to-moment shifts in client affect and behavior, respond creatively to unexpected clinical material, and tolerate the uncertainty inherent in therapeutic work [6], [19]. For clients, improvisational exercises promote mindful awareness, reduce rumination about past or future, and strengthen capacity for spontaneous emotional expression [3], [12].
The theoretical mechanism emphasizes that improvisation disrupts habitual cognitive and behavioral patterns by requiring novel, in-the-moment responses. This process parallels exposure-based and behavioral activation approaches in cognitive-behavioral therapy, where engagement with present experience reduces avoidance and expands behavioral repertoires [15], [18]. Several studies report that participants describe increased comfort with uncertainty and enhanced ability to “stay present” during challenging interpersonal situations following improvisation training [6], [15], [19].
3.2 Play and the Safe Fiction Frame
A second theoretical framework draws upon play theory and the concept of the “safe fiction frame” in drama therapy [4], [5], [11]. Improvisation creates a bounded space explicitly marked as “not real”, wherein participants can experiment with emotions, behaviors, and identities without real-world consequences. This fictional frame provides psychological safety for exploring threatening material, rehearsing new behaviors, and expressing difficult emotions [4], [11], [16].
The play frame operates through several mechanisms. First, it enables desidentification: participants can attribute actions and emotions to fictional characters rather than their “real” selves, reducing shame and defensiveness [11], [29]. Second, it permits controlled risk-taking: participants can experiment with unfamiliar roles, express taboo emotions, or confront feared situations within the protective container of “just playing” [4], [5]. Third, it facilitates perspective-taking: by embodying diverse characters and viewpoints, participants develop cognitive flexibility and empathy [8], [10], [30].
This framework can be particularly helpful in therapeutic situations where direct confrontation of clinical material may be overwhelming or counterproductive [2], [11], [29]. The fiction frame allows gradual exposure to difficult content while maintaining a sense of control and safety. Qualitative studies consistently report that participants value the “playful” quality of improvisation and describe feeling “safe to take risks” within the theatrical context [11], [17], [29].
3.3 Co-Creation and Socio-Cognitive Learning
A third theoretical perspective emphasizes improvisation as fundamentally collaborative and socially embedded. Unlike individual expressive arts modalities, improvisation requires continuous coordination with scene partners, making social interaction the primary medium of therapeutic change [1], [8], [10]. This framework draws upon social learning theory, theory of mind research, and interpersonal neurobiology to explain how collaborative improvisation enhances social cognition and interpersonal skills [8], [10], [14].
The core mechanism involves co-creation: participants must continuously attend to partners’ verbal and nonverbal signals, make and respond to “offers” (contributions to the emerging scene), and jointly construct coherent narratives without predetermined plans [1], [8]. This process demands and develops multiple socio-cognitive capacities, including: joint attention, turn-taking, perspective-taking, nonverbal communication, emotional recognition, and cooperative problem-solving [8], [10], [14], [30].
Empirical support for this framework comes primarily from studies with autism spectrum populations, where improvisation interventions target core social-cognitive development. Research demonstrates that structured improvisation exercises improve social reciprocity, reduce social anxiety, and enhance theory of mind capacities in individuals with ASD [10], [30]. The collaborative nature of improvisation provides repeated, naturalistic practice in social coordination within a supportive, low-stakes context [8], [10].
This framework also explains outcomes in group therapy settings, where improvisation fosters group cohesion, mutual support, and collective meaning-making [4], [21]. Participants report feeling “connected” to group members and describe improvisation as creating shared experiences that strengthen therapeutic relationships [4], [17], [21].
3.4 Clinician Skill Transfer and Professional Development
A fourth theoretical framework focuses on improvisation as professional training for mental health clinicians. This perspective posits that improvisation skills, such as active listening, flexible responding, tolerance of ambiguity, creative problem-solving, and playful engagement, directly transfer to clinical practice and enhance therapeutic effectiveness [6], [19], [22].
The theoretical mechanism involves experiential learning: by practicing improvisation, clinicians embody therapeutic stances (e.g., acceptance, curiosity, spontaneity) rather than merely learning about them cognitively [19], [22]. Improvisation training cultivates specific clinical competencies, including: (1) tracking and responding to nonverbal communication; (2) managing uncertainty and therapeutic impasses; (3) maintaining presence during emotionally intense sessions; (4) generating creative interventions in the moment; and (5) balancing structure with flexibility [6], [19], [22].
Empirical studies with psychiatry residents, psychotherapy trainees, and practicing clinicians report that improvisation training reduces burnout, increases self-compassion, enhances playfulness in clinical work, and improves confidence in managing difficult clinical situations [6], [15], [19]. The framework suggests that improvisation addresses professional stressors by reframing uncertainty as creative opportunity rather than threat, fostering a growth mindset toward clinical challenges [6], [15].
The improv techniques of “offers” and response styles have been proposed as frameworks for analyzing and teaching therapeutic interactions, suggesting that improvisation provides a meta-language for understanding relational dynamics in psychotherapy [19], [22]. This theoretical development positions improvisation not merely as an adjunctive technique but as a foundational skill set for effective clinical practice across therapeutic modalities.
3.5 Action-Based Access for Nonverbal Populations
A fifth theoretical framework emphasizes improvisation’s capacity to engage individuals with limited verbal-cognitive abilities through embodied, action-based modalities [2], [7], [17], [30]. This perspective draws upon embodied cognition theory, which posits that cognitive and emotional processes are grounded in sensorimotor experience rather than solely in abstract symbolic thought [7], [17].
Improvisation reduces reliance on verbal articulation by centering physical action, gesture, sound, and movement as primary modes of expression and communication [2], [7], [17]. This action-based quality makes improvisation accessible to populations for whom traditional talk therapy is ineffective or inappropriate, including individuals with intellectual disabilities, severe autism, dementia, and young children [2], [17], [30].
The theoretical mechanism involves bypassing verbal-cognitive bottlenecks to access emotional and social capacities through embodied channels. Physical improvisation exercises (e.g., mirroring, movement games, nonverbal scene work) engage participants in social interaction and emotional expression without requiring verbal fluency or abstract reasoning [2], [7], [17]. This approach aligns with bottom-up therapeutic models that prioritize somatic and sensory experiences as pathways to psychological change [7], [17].
Empirical support comes from studies demonstrating high feasibility, engagement, and satisfaction in populations with intellectual disabilities and nonverbal autism, where participants who struggle with verbal therapies show sustained participation and observable improvements in social interaction during improvisation sessions [2], [17], [30].
4. Therapeutic Benefits and Core Mechanisms
Across diverse populations and settings, improvisational theater interventions produce a cluster of interrelated therapeutic benefits. This section further explores reported outcomes organized by core therapeutic mechanisms, integrating quantitative findings and qualitative themes from the reviewed literature.
4.1 Social Reciprocity and Interpersonal Skills
Enhanced social reciprocity emerges as the most consistently reported outcome across studies, particularly in populations with social-cognitive deficits. Improvisation exercises explicitly target turn-taking, joint attention, nonverbal attunement, and cooperative interaction, fundamental components of social competence [1], [8], [10], [14], [30].
Studies with autism spectrum populations report improvements in social engagement, reduced social anxiety, and enhanced social cognition following improvisation interventions [10], [30]. One quasi-experimental study with seven children with ASD found that all participants improved in identifying others’ emotions, with one student showing a 66% increase in emotion recognition accuracy [30]. Participants also progressed in expressing their own emotions, with some moving from no response to verbally and physically expressing multiple emotions [30].
In intellectual disability populations, a pilot feasibility study (N=24) reported high sustained participation and strong satisfaction scores, indicating that improvisation successfully engages individuals with social and communication challenges [17]. Qualitative data from this study described participants demonstrating increased peer interaction and communication skills during improvisation sessions [17].
Group therapy applications across psychiatric populations consistently report enhanced group cohesion, mutual support, and interpersonal connection [4], [21]. Participants describe feeling “more connected” to group members and report that improvisation creates shared experiences that strengthen therapeutic relationships more rapidly than traditional group therapy formats [4], [21], [29].
The mechanism underlying these social benefits appears to involve repeated, naturalistic practice in social coordination within a supportive, low-stakes context. Improvisation provides immediate feedback on social behaviors, rewards cooperative interaction, and scaffolds social skills through structured games and exercises that gradually increase complexity [8], [10], [14].
4.2 Emotional Expression and Awareness
Improv creates opportunities for emotions to emerge, be expressed, and be explored within the safe fiction frame [3], [4], [11], [29]. Multiple studies report that participants demonstrate increased emotional expression, expanded emotional vocabulary, and enhanced emotional awareness following improvisation interventions [2], [11], [18], [29], [30].
In eating disorder recovery populations, qualitative research found that therapeutic theater facilitated emotional self-regulation, including connecting to emotions, expanding comfort zones, and practicing authentic emotional expression [29]. Participants reported that improvisation helped them “take up space” emotionally and physically, challenging patterns of emotional suppression and self-minimization characteristic of eating disorders [29].
Studies with psychiatric day hospital populations describe participants using improvisation to explore difficult emotions in a contained, supportive environment [4]. The theatrical frame allows expression of anger, sadness, fear, and other challenging affects without the interpersonal consequences that might occur in everyday interactions [4], [11].
For trauma survivors, including internally displaced persons with PTSD, drama therapy incorporating improvisation enabled participants to “recall awful situations, explore problems, and connect with life realities” while maintaining psychological safety [2]. The intervention fostered self-appraisal, self-esteem, and emotional integration, leading to reported improvements in psychosocial functioning and well-being [2].
The mechanism appears to involve the fiction frame’s capacity to create psychological distance from overwhelming emotions, allowing gradual exposure and processing. Improvisation also provides embodied channels for emotional expression, bypassing verbal-cognitive defenses that may block emotional awareness in traditional talk therapy [7], [11], [17].
4.3 Tolerance of Uncertainty and Flexibility
Training in spontaneous co-creation increases present-centered responding and comfort with ambiguity, which clinicians and participants link to reduced stress and enhanced adaptive functioning [3], [6], [15], [19]. This benefit is particularly salient in clinician training applications, where tolerance of uncertainty is essential for managing complex clinical situations [6], [15], [19].
A pilot study with psychiatry residents (N=14) found that a brief improvisation training program produced decreases in burnout indicators and increases in playfulness and self-compassion [15]. Participants reported feeling more comfortable with uncertainty in clinical work and described improvisation as helping them “let go of needing to have all the answers” [15].
For clients, improvisation cultivates cognitive flexibility and reduces rigid, all-or-nothing thinking patterns. Studies with adolescents and eating disorder populations report that participants develop greater tolerance for mistakes, increased willingness to take interpersonal risks, and reduced perfectionism following improvisation interventions [8], [11], [29].
The mechanism involves repeated exposure to unpredictable situations within the supportive improvisation context, where “mistakes” are reframed as creative opportunities and uncertainty is normalized as inherent to the process [3], [6], [19]. This experiential learning appears more effective than didactic instruction in shifting attitudes toward uncertainty and failure [6], [15], [19].
4.4 Creativity and Narrative Capacity
Improvisation enhances divergent thinking, narrative planning, and story construction capacities [1], [7], [8]. A controlled pre-post study with adolescents (n=27) found that participants who completed improvisational theater courses demonstrated significantly improved narrative coherence and planning abilities compared to baseline [8]. Participants showed enhanced capacity to construct well-structured stories with clear beginnings, middles, and endings, as well as improved ability to elaborate on narrative details [8].
These narrative gains have therapeutic implications beyond storytelling per se. Narrative capacity is central to identity formation, meaning-making, and psychological integration [7], [8], [11]. Studies with eating disorder populations found that therapeutic theater supported identity work and the construction of recovery narratives, helping participants articulate coherent stories about their experiences and envision future possibilities [29].
Creativity benefits extend to problem-solving and adaptive coping. Participants across studies report feeling “more creative” in approaching life challenges and describe improvisation as expanding their repertoire of behavioral and emotional responses [3], [11], [15], [19].
The mechanism involves the improvisational principle of “yes, and”, that is accepting and building upon whatever emerges, which inhibits premature closure or evaluation [1], [3], [19]. Repeated practice in generating novel responses to unexpected prompts appears to generalize to enhanced creative capacity in non-theatrical contexts [8], [15], [19].
4.5 Engagement and Therapeutic Alliance
High feasibility, sustained participation, and strong satisfaction ratings are consistently reported across populations and settings [2], [8], [11], [15], [17], [29]. These engagement outcomes are particularly notable given that many studies involve populations with low treatment adherence or limited access to conventional therapies [2], [17], [30].
The pilot study with intellectual disability populations reported long average participation duration and a Client Satisfaction Questionnaire (CSQ-8) mean score indicating high satisfaction [17]. Qualitative data revealed that participants looked forward to sessions, actively engaged in exercises, and expressed disappointment when the program ended [17].
In eating disorder recovery, participants described therapeutic theater as providing “continued containment” and fostering relationships that supported recovery more effectively than traditional aftercare approaches [29]. The group cohesion and social connection generated through improvisation appeared to enhance motivation and treatment adherence [29].
The mechanism underlying high engagement likely involves multiple factors: the playful, non-clinical framing of improvisation reduces stigma and resistance; the action-based modality maintains attention and interest; the collaborative nature fosters social connection and mutual accountability; and the creative process provides intrinsic rewards that sustain motivation [2], [8], [11], [17], [29].
5. Clinical Outcomes by Population
This section outlines clinical outcomes organized by population, examining specific findings, intervention characteristics, and population-specific considerations across seven major application areas.
5.1 Autism Spectrum Disorder
Improvisational theater interventions for autism spectrum disorder (ASD) target core deficits in social communication, social cognition, and behavioral flexibility. Studies report improvements in social engagement, emotion recognition, anxiety reduction, and theory of mind capacities [10], [30].
A quasi-experimental study with seven boys with ASD implemented four weeks of theater activities and games (puppet-making, role-playing, movement to music) conducted for 30 minutes twice weekly [30]. Pre-post assessments, teacher interviews, and field observations revealed that all participants improved in identifying others’ emotions, with one student showing a 66% increase [30]. Students also progressed in expressing their own emotions, with some moving from no response to verbally and physically expressing all three target emotions (happy, sad, angry) [30]. The program enhanced peer interaction, communication skills, and ability to cope with difficult situations [30].
Another study examining improvisation as a social cognition intervention for autism reported preliminary evidence of reduced anxiety and nervousness, along with improved social cognition and engagement [10]. The intervention emphasized structured improvisation games that scaffold social interaction through clear rules and predictable formats, gradually increasing social complexity as participants develop competence [10].
Population-specific considerations for ASD include the need for: (1) high structure and predictability in early sessions to reduce anxiety; (2) explicit teaching of improvisation “rules” that may be implicit for neurotypical participants; (3) visual supports and concrete language; (4) sensory accommodations for individuals with sensory sensitivities; and (5) individualized pacing based on social-cognitive developmental level [10], [30].
Limitations of ASD research include small sample sizes, short intervention durations (typically 4-8 weeks), lack of active control groups, and limited follow-up to assess maintenance of gains [10], [30]. Future research should examine dose-response relationships, optimal intervention intensity, and mechanisms linking specific improvisation exercises to social-cognitive outcomes [10], [30].
5.2 Intellectual and Developmental Disabilities
Research with intellectual and developmental disability populations demonstrates high feasibility, strong engagement, and participant satisfaction with improvisation interventions [17]. A pilot feasibility study (N=24) implemented an improvisational theater program for people with intellectual disabilities and mental health problems [17]. The study reported long average participation duration and a CSQ-8 mean score indicating high satisfaction [17]. Qualitative findings described participants demonstrating increased peer interaction, communication skills, and emotional expression during sessions [17].
The action-based, nonverbal nature of improvisation makes it particularly accessible for this population, where verbal-cognitive demands of traditional therapies may be prohibitive [17]. Improvisation exercises emphasizing physical movement, gesture, sound, and play engage participants through embodied channels that do not require abstract reasoning or verbal fluency [17].
Population-specific considerations include: (1) simplified instructions and modeling; (2) shorter session durations with frequent breaks; (3) emphasis on physical and sensory improvisation over verbal scene work; (4) consistent routines and familiar warm-up activities; and (5) staff training to support participants with varying cognitive and communication abilities [17].
Methodological limitations include the absence of standardized outcome measures appropriate for this population, lack of control groups, and reliance on qualitative and observational data rather than validated clinical assessments [17]. Future research should develop and validate outcome measures sensitive to change in intellectual disability populations, examine long-term outcomes, and compare improvisation to other group-based interventions [17].
5.3 Adolescents and Educational Settings
Improvisation interventions in educational settings with adolescents target social-emotional development, narrative skills, creativity, and inclusion [7], [8], [9]. A controlled pre-post study found that adolescents (n=27) who completed improvisational theater courses demonstrated significantly improved narrative coherence and planning abilities [8]. Participants showed enhanced capacity to construct well-structured stories and improved ability to elaborate on narrative details [8].
Educational applications emphasize improvisation’s capacity to develop communication skills, self-confidence, perspective-taking, and collaborative problem-solving in non-clinical populations [7], [8], [9]. Studies report that improvisation creates inclusive classroom environments where diverse learners can participate and contribute, regardless of academic ability or language proficiency [9].
A study examining theater as an educational resource for inclusion found that improvisation activities promoted social integration, reduced stigma toward students with disabilities, and enhanced empathy and cooperation among all students [9]. The collaborative, non-competitive nature of improvisation created opportunities for students with diverse abilities to interact as equals [9].
Population-specific considerations for adolescents include: (1) attention to peer dynamics and social hierarchies; (2) age-appropriate content and themes; (3) sensitivity to self-consciousness and performance anxiety common in adolescence; (4) integration with academic curricula when implemented in schools; and (5) cultural responsiveness to diverse student backgrounds [7], [8], [9].
Limitations include variability in implementation across educational settings, lack of long-term follow-up, and limited examination of mechanisms linking improvisation to developmental outcomes [8], [9]. Future research should examine whether gains in narrative and social skills generalize to academic performance and real-world social functioning [8].
5.4 Eating Disorder Recovery
Therapeutic theater incorporating improvisation has been explored as an aftercare intervention for individuals in eating disorder recovery [29]. A qualitative study with seven participants (six women, one man) aged 23-33 examined a 7-week co-active therapeutic theater model meeting twice weekly for three-hour sessions, culminating in a public performance [29].
Findings revealed that therapeutic theater provided continued containment, fostered relationships, and supported emotional self-regulation (connecting to emotions, expanding comfort zones) [29]. The intervention advanced psychological recovery by addressing unfinished business, supporting participants to “take up space” physically and emotionally, promoting authenticity, improving body relationship, and fostering sense of agency [29]. Participants reported increased social connection, reduced anxiety, and enhanced emotional expression [29]. The process expedited healing and built group cohesion more quickly than traditional therapy [29].
Population-specific considerations include: (1) attention to body image concerns and physical self-consciousness; (2) careful framing of performance elements to avoid triggering perfectionism or appearance-focused anxiety; (3) emphasis on process over product; (4) integration with ongoing recovery support; and (5) trauma-informed approaches given high comorbidity of trauma in eating disorder populations [29].
Methodological limitations include researcher bias, small sample size preventing saturation, absence of control group, and limited generalizability due to specialized context [29]. Future research should rework the model based on participant feedback, expand to other populations (e.g., substance use disorders), compare with other aftercare therapies, and develop training programs for the model [29].
5.5 Psychiatric Populations and Day Hospital Settings
Studies with general psychiatric populations and day hospital users report that improvisation enhances group cohesion, agency, insight, and perceived well-being [4]. A qualitative study with psychiatric day hospital users in Brazil found that participants described increased engagement, role flexibility, and sense of agency through theater activities [4]. Participants reported feeling more connected to others, more capable of expressing themselves, and more hopeful about their futures [4].
Improvisation in psychiatric settings serves multiple functions: (1) providing structured social interaction for individuals with impaired social functioning; (2) creating opportunities for identity exploration and role experimentation; (3) fostering hope and future orientation through creative expression; (4) building group cohesion and mutual support; and (5) reducing stigma by reframing mental health challenges through artistic metaphors [4], [18], [21].
A study examining theater’s effectiveness on anxiety, mental health, and personality in youth referred to cultural centers found improvements in anxiety levels and mental health indicators following theater participation [18]. The intervention provided a normalizing, community-based context for mental health promotion outside clinical settings [18].
Population-specific considerations include: (1) assessment of symptom severity and stability before participation; (2) clear safety protocols for managing psychiatric crises; (3) integration with ongoing psychiatric treatment; (4) attention to medication side effects that may affect participation (e.g., sedation, motor effects); and (5) flexibility to accommodate fluctuating symptom levels [4], [18].
Limitations include lack of diagnostic specificity (studies often include heterogeneous psychiatric populations), absence of standardized outcome measures, and limited examination of which participants benefit most from improvisation interventions [4], [18]. Future research should examine outcomes by diagnostic category, identify predictors of treatment response, and compare improvisation to other group-based psychiatric interventions [4].
5.6 Trauma and Displaced Populations
Drama therapy incorporating improvisation has been applied to trauma recovery, particularly with displaced populations experiencing post-traumatic stress [2]. A program evaluation with internally displaced persons (IDPs) in Nigeria (N=40 adults) implemented group therapy sessions involving improvisational techniques, storytelling, role-playing, and cultural performances [2].
Findings indicated that drama therapy enabled participants to recall traumatic situations, explore problems, and connect with life realities in a contained manner [2]. The intervention fostered self-appraisal, self-esteem, self-presentation, self-efficacy, and self-actualization, leading to reported psychosocial efficacy and holistic well-being [2]. Participants described feeling validated, heard, and supported through the collective creative process [2].
Population-specific considerations for trauma populations include: (1) trauma-informed facilitation that prioritizes safety and choice; (2) careful pacing to avoid overwhelming retraumatization; (3) cultural sensitivity and incorporation of culturally relevant performance traditions; (4) attention to group composition and power dynamics; (5) integration with other trauma-focused interventions; and (6) recognition of ongoing stressors in displaced populations [2].
Limitations include lack of standardized trauma outcome measures, absence of control groups, and limited follow-up to assess sustained benefits [2]. The study also noted that drama therapy practice is not yet established in Nigeria due to lack of trained practitioners and supporting literature [2]. Future research should examine trauma-specific outcomes using validated measures, compare drama therapy to evidence-based trauma treatments, and develop culturally adapted protocols for diverse trauma-affected populations [2].
5.7 Clinician Training and Burnout Prevention
Improvisation training for mental health clinicians and trainees targets professional skills, therapeutic presence, and burnout prevention [6], [15], [19], [22]. A pilot study with psychiatry residents (N=14) implemented an improvisational theater program to reduce burnout [15]. The intervention produced decreases in burnout indicators and increases in playfulness and self-compassion [15]. Participants reported feeling more comfortable with uncertainty in clinical work and described improvisation as enhancing their therapeutic presence and creativity [15].
Theoretical and clinical papers describe improvisation as cultivating core clinical competencies, including active listening, flexible responding, tolerance of ambiguity, creative problem-solving, and playful engagement [19], [22]. Improvisation training provides experiential learning in therapeutic stances (acceptance, curiosity, spontaneity) that may be difficult to teach through didactic methods alone [19], [22].
Studies with family therapists and psychotherapy trainees report that improvisation enhances clinicians’ capacity to track and respond to nonverbal communication, manage therapeutic impasses, maintain presence during emotionally intense sessions, and generate creative interventions in the moment [6], [19], [22].
Population-specific considerations for clinician training include: (1) addressing performance anxiety and self-consciousness common among clinicians new to improvisation; (2) explicit connection between improvisation principles and clinical practice; (3) integration with existing training curricula; (4) attention to power dynamics in training contexts; and (5) ongoing practice opportunities to sustain skills [6], [15], [19].
Limitations include small sample sizes, lack of control groups, reliance on self-report measures, and limited examination of whether improvisation training translates to improved clinical outcomes for clients [6], [15], [19]. Future research should examine client outcomes when treated by improvisation-trained versus control clinicians, identify optimal training dosage and format, and explore mechanisms linking improvisation skills to clinical effectiveness [6], [15].
6. Limitations of Current Evidence
Beyond the methodological considerations detailed above, several additional limitations characterize the current evidence base for improvisational theater in therapeutic contexts.
Publication Bias and Selective Reporting: The reviewed literature likely reflects publication bias favoring positive findings, as studies reporting null or negative results are less likely to be published [1]. This bias may lead to overestimation of therapeutic benefits and underrepresentation of potential adverse effects or contraindications. Few studies report negative outcomes, dropout rates, or participant dissatisfaction, suggesting selective reporting [17], [29].
Intervention Heterogeneity: Improvisation interventions vary substantially in theoretical orientation, structure, duration, intensity, facilitator training, and specific techniques employed [1], [4], [8], [17], [19]. This heterogeneity makes it difficult to identify “active ingredients” or determine which intervention components are necessary and sufficient for therapeutic change [1], [17]. Studies rarely provide detailed intervention manuals or protocols that would enable replication [17], [29].
Facilitator Effects: The therapeutic impact of improvisation likely depends substantially on facilitator skill, training, and therapeutic orientation, yet few studies systematically examine or control for facilitator effects [17], [19], [29]. Facilitators in reviewed studies range from trained drama therapists to theater artists without clinical training to mental health clinicians with improvisation experience, introducing substantial variability in intervention delivery [2], [4], [17], [19].
Lack of Active Control Groups: Most studies lack active control conditions, making it impossible to determine whether observed benefits are specific to improvisation or reflect nonspecific factors such as group participation, attention from facilitators, or expectancy effects [8], [10], [15], [17], [30]. Future research should compare improvisation to structurally equivalent control interventions (e.g., other group activities matched for duration, social interaction, and facilitator attention) to isolate improvisation-specific effects [10], [17].
Cultural and Contextual Specificity: The majority of reviewed studies are conducted in Western, educated, industrialized, rich, and democratic (WEIRD) contexts, with limited examination of cultural adaptation or effectiveness in diverse cultural settings [2], [9]. The few studies conducted in non-Western contexts (e.g., Nigeria, Brazil) highlight the importance of cultural adaptation but provide insufficient detail about how improvisation principles translate across cultural contexts [2], [4], [9].
Mechanism Ambiguity: While multiple theoretical frameworks propose mechanisms of therapeutic change, few studies empirically test these mechanisms through mediation analyses or experimental manipulation of proposed active ingredients [1], [8], [10]. As a result, it remains unclear whether improvisation produces therapeutic benefits through the proposed mechanisms (e.g., present-moment awareness, safe fiction frame, social learning) or through alternative pathways [1], [10].
Adverse Effects and Contraindications: The literature provides minimal information about potential adverse effects, contraindications, or participants for whom improvisation may be ineffective or harmful [17], [29]. While studies generally report high satisfaction and engagement, the absence of systematic adverse event monitoring raises concerns about selective reporting [17]. Potential risks might include exacerbation of social anxiety, triggering of trauma responses, or group conflict, yet these possibilities are rarely discussed [2], [11]
Conclusion
The review identifies five primary theoretical frameworks explaining therapeutic mechanisms: present-centered spontaneity, safe fiction frames, co-creative socio-cognitive learning, clinician skill transfer, and action-based access for nonverbal populations. These frameworks provide complementary explanations for how improvisation produces therapeutic change through embodied, collaborative, and playful processes.
Across populations, improvisation interventions demonstrate consistent benefits in social reciprocity, emotional expression, tolerance of uncertainty, narrative capacity, and therapeutic engagement. Clinical outcomes are most extensively documented in autism spectrum disorder, intellectual disabilities, adolescent populations, eating disorder recovery, psychiatric settings, trauma-affected populations, and clinician training contexts. Reported outcomes include reduced anxiety, improved social cognition, enhanced group cohesion, decreased burnout, and high participant satisfaction.
However, the evidence base is characterized by significant methodological limitations. The literature consists predominantly of pilot studies, qualitative investigations, and small quasi-experimental designs, with large-scale randomized controlled trials notably absent. Sample sizes are consistently small, outcome measurement lacks standardization, and long-term follow-up data are scarce. These limitations preclude definitive conclusions about efficacy and constrain understanding of mechanisms, moderators, and optimal intervention parameters.
Despite these limitations, the convergence of findings across diverse populations, settings, and methodological approaches suggests that improvisational theater holds genuine therapeutic promise. The action-based, collaborative, and playful nature of improvisation appears to engage participants who may not respond to traditional verbal therapies, while the safe fiction frame enables exploration of difficult material in a contained manner. The emphasis on present-moment awareness, acceptance, and creative flexibility aligns with core therapeutic processes across multiple evidence-based treatment modalities.
The field now stands at a critical juncture. Preliminary evidence and theoretical frameworks provide a foundation for more rigorous investigation, but advancement requires substantial methodological improvements. Priority directions include conducting adequately powered randomized controlled trials, developing standardized outcome measures, examining long-term outcomes, investigating mechanisms of change, and comparing improvisation to evidence-based alternatives. Such research would establish whether improvisation-based interventions merit inclusion in the repertoire of evidence-based mental health treatments.
For clinicians and program developers, current evidence supports cautious optimism about improvisation’s therapeutic potential, particularly for populations with social-cognitive deficits, limited verbal abilities, or poor engagement with traditional therapies. However, practitioners should recognize the preliminary nature of existing evidence and the need for ongoing outcome monitoring, cultural adaptation, and integration with established treatment approaches. Improvisation should be viewed as a promising adjunctive or alternative intervention requiring further empirical validation rather than a replacement for evidence-based treatments.
Improvisational theater represents an innovative and theoretically grounded approach to therapeutic intervention with demonstrated feasibility and preliminary evidence of benefit across diverse populations. Realizing its full potential requires sustained research investment, methodological rigor, and collaborative efforts across disciplines to establish efficacy, elucidate mechanisms, and develop evidence-based protocols for clinical practice.
