What this trial studies

This study investigates the role of oxytocin in enhancing trust towards therapists through the presence of dogs during therapy sessions. Participants will receive either an oxytocin nasal spray, engage in an Animal-Assisted Intervention, or receive a placebo. The research aims to clarify the neuroendocrine mechanisms that may facilitate human-animal bonding and improve therapeutic outcomes for individuals with depressive symptoms. By examining these interactions, the study seeks to advance the understanding of animal-assisted interventions in mental health care.

Why it matters

Potential benefit: If successful, this study could improve therapeutic relationships and outcomes for patients with depressive symptoms through enhanced trust facilitated by oxytocin and dog presence.

How similar studies have gone: While the role of oxytocin in human bonding is well-established, the specific application of oxytocin in enhancing trust through human-animal interactions is still being explored, making this study a novel investigation.
