Background: Trauma and its sequelae is recognised as a major morbidity factor in people with intellectual disabilities, however, a lack of inquiry into how health care professionals address trauma in this adult population exists. Aims: To explore specialist intellectual disability practitioners perspectives on current health provision and developments to address trauma. Methods: Twenty-five qualitative interviews were conducted with practitioners across 6 health service areas in the UK. Data were analysed using thematic content analysis. Findings: Seven central themes emerged: (a) unmasked trauma; (b) trauma informed care; (c) person-centred care and support; (d) multi-disciplinary working; (e) reasonable adjustments; (f) barriers to treatment and (g) awareness, training and education. Conclusion: Trauma-informed care and multi-disciplinary working are essential components for future service development. Advances in the evidence-base for effective psychological interventions for PTSD and training and education of health care staff are needed in order to improve service provision amongst this population.
