The workshop will outline research in applied improv related to mental health and psychotherapy. We will cover how improv supports mental health even when it is not practiced with a psychotherapeutic aim and by psychotherapists and also studies of applied improv as a deliberate psychotherapeutic intervention. We will explore improvisational training principles that have proven to be beneficial for mental health and psychotherapy with various target groups (considering the age or type of mental health difficulties). Another area of research that the workshop will tackle is how improv supports the professional development of people working in caring professions (such as therapists, social workers, educators, etc.). Applied improvisation offers vast potential for training programs in those professions of which some have been already explored in research. Most of the studies have been written and published in the last eight years so there is apparent growing interest in AI in academia and mental health care.
