Psychological Interventions for Intellectual Disabilities

Individuals with intellectual disabilities often experience elevated rates of mental health difficulties, including anxiety, depression and behavioural challenges. Psychological interventions for this population aim to promote adaptive functioning, improve emotional well-being and reduce distress by adapting established therapeutic approaches to cognitive and communicative needs. Key strategies include structured therapies such as cognitive behavioural therapy (CBT) and behavioural activation, which are modified through simplified language, visual aids or caregiver involvement. Complementary approaches incorporate expressive arts, digital platforms and social skills training to enhance engagement and generalisation. Effective interventions are tailored to the individual’s level of support, cultural context and co-occurring conditions. Global developments emphasise inclusive design, community integration and a rights-based perspective that positions people with intellectual disabilities as active participants in their own care. Despite growing evidence, barriers persist in access, clinician training and long-term follow-up, underlining the need for high-quality trials and implementation research across diverse settings.
