ABSTRACT Background Art therapy is one rehabilitation treatment which enables youth in secure care to express unresolved conflicts, increase self-esteem, and gain insight to personal experiences in a creative and supportive therapeutic space. Aims This study investigated hope and resilience outcomes following art therapy for youth residing in a secure care centre located in Canada. Methods In this pre–post experimental design study, thirteen (N = 13) youth, ages 12–19, received 12 weekly individual art therapy sessions. Hope, resilience, and goals were measured using the Children’s Hope Scale (CHS), the Resilience Scale (RS-25), and the Bridge Drawing with Path (BDP) art-based assessment. Results Results indicated that the 12 weekly individual art therapy sessions enhanced hope and resilience in youth residing in secure care by 29% and 16%, respectively. Conclusions Secure care environments may benefit from incorporating art therapy as a rehabilitation treatment to improve youths’ levels of hope, resilience, self-determination, and future pathways. Implication for Future Research Future studies should utilise a group design with a control group to evaluate the effects of art therapy on youth residing in secure care environments. Plain-language summary Art therapy is one rehabilitation treatment which enables youth in secure care to express unsettled conflicts, increase self-esteem, and gain understanding of personal experiences in a creative and supportive therapeutic space. This study investigated the effectiveness of art therapy on the levels of hope and resilience in youth residing in a secure care centre located in Canada.

Secure care environments may benefit from including art therapy as a rehabilitation treatment to improve youths’ levels of hope, resilience, self-determination, and future pathways. Future studies should use a group design with a control group to measure the effects of art therapy on youth residing in secure care environments.
