Longitudinal data from a cluster RCT trial (The PBS trial) on people suffering from intellectual disability and challenging behaviour. A total of 244 individuals across 23 sites were enrolled in the trial: 136 in the control (t=1) and 108 in the active intervention (t=2). Health economic outcome data were collected via self-reported questionnaires at three time points throughout the study: baseline (time=1), 6 months (time=2) and 12 months (time=3) follow-up, and included utility scores related to quality of life and costs. Baseline data are available for age, gender, ethnicity, living status, type of carer, marital status, and disability level variables.
