Short-Term Psycho-Education for Caregivers to Reduce Overmedication of People with Intellectual Disabilities (SPECTROM): Development and Field Testing.

People with intellectual disabilities (PwID) are at a higher risk of developing challenging behaviours (CB). Despite the poor evidence for the effectiveness of medications in managing CB, they are used widely among PwID (50-63%). The aims of our study were to develop a training programme, SPECTROM for support staff to help reduce overmedication in PwID and carry out field testing of SPECTROM including a process evaluation.
