Dog-Assisted Therapy in Adolescents Attending a Child and Adolescent Mental Health Day Hospital

This study aimed to evaluate the feasibility and effectiveness of a dog-assisted therapy program integrated into a Child and Adolescent Mental Health Day Hospital, as well as to explore participants' subjective experiences. Mental health disorders in adolescence are common and often require intensive treatment approaches. Day hospitals provide structured care while allowing adolescents to remain in their family and social environments. Dog-assisted therapy has been proposed as a complementary intervention that may support emotional regulation, reduce distress, and enhance motivation and engagement in treatment. A mixed-methods study was conducted, combining a randomized controlled trial with a qualitative phenomenological analysis. A total of 70 adolescents aged 12 to 18 years attending a mental health day hospital were included. Participants were randomly assigned to an experimental group, which received dog-assisted therapy in addition to treatment as usual, or to a control group that received treatment as usual only. The intervention consisted of eight structured sessions of dog-assisted therapy, each lasting approximately 45 minutes. Clinical and emotional outcomes were assessed before and after the intervention using standardized instruments. In addition, immediate emotional changes were evaluated before and after each session. A qualitative component based on semi-structured interviews was conducted to better understand participants' experiences. The study seeks to provide evidence on whether dog-assisted therapy can be a useful complementary intervention in adolescent mental health care, particularly in improving immediate emotional regulation, motivation, and therapeutic engagement. This is an interventional trial registered retrospectively after study completion. Data were collected between \[01/01/2024\] and (31.12.2025\]
