Participants also free wrote after the workshops, reflecting on their experiences. Results The surveys showed that there was a statistically significant shift in a positive direction in each domain studied. Themes that emerged from the free-writing responses were those of play, social acceptance, gratitude, and community. Conclusions Findings demonstrate that structured theatre activities produce quality of life benefits across all domains. This pilot study indicates the potential for such theatre-in-health projects as a tool for quality of life improvement.
