A Systematic Review of the Efficacy of Behavioural and Psychosocial Intervention Therapies for Mental Health Disorders

This systematic review takes a close look at how effective behavioural and psychosocial interventions are for mental health disorders, pulling together evidence from studies published between 2020 and 2025.It primarily centralises on three specific groups-adolescents dealing with anxiety disorders, adults coping with post-traumatic stress disorder (PTSD), and individuals facing schizophrenia-spectrum disorders.The review combines insights from randomized controlled trials (RCTs), meta-analyses, and top-notch observational research.Technology-assisted cognitive behavioural therapy (CBT), which includes computerized and app-based options, showed effectiveness on par with traditional face-to-face CBT for adolescent anxiety, plus it offers extra benefits in terms of accessibility and engagement.For PTSD, trauma-focused treatments like CBT and EMDR led to significant reductions in symptoms and better emotional regulation, although more research is needed to differentiate trauma-informed approaches and evaluate their effects on refugee populations as this was limited in the results obtained.Family-based psychosocial interventions, especially psychoeducation programs, notably lowered relapse rates and enhanced outcomes for caregivers in schizophrenia-spectrum disorders.Overall, these findings highlight the importance of personalized, context-sensitive interventions and advocate for the integration of digital tools, trauma-informed care, and family-inclusive strategies into modern mental health practices.josha.org
