Aim To investigate whether staff training in positive behavioural support (PBS) improves service users’ quality of life (QOL).

Method The World Health Organization’s QOL measure (WHOQOL-BREF) was used to assess service users’ QOL in supported living homes where staff had received PBS training versus supported living homes where staff had not received PBS training.

Results Although QOL was good across the board, environmental QOL was found to be significantly better in supported living homes where staff had been trained in PBS.

Conclusion PBS training influences environmental QOL for service users positively and should continue to be the focus of organisational investment.
