Aim Good practice guidelines aim to promote equity and quality in service provision to improve the outcomes, experiences and quality of life for service users. The aim of the study was to evaluate the extent to which the practices of NHS services in Scotland for people with an intellectual disability and dementia are consistent with a range of quality indicators that cover screening, assessment and intervention.

Method Staff from ten intellectual disability services in Scotland completed an online survey rating the extent to which their service met quality indicators adapted from the British Psychological Society, Division of Clinical Psychology, Royal College of Psychiatrists’ Good Practice Standards-Self-Assessment Checklist.

Results Areas most commonly ‘fully met’ related to assessment and diagnosis and those most commonly ‘not/only partially met’ related to areas, such as flexible funding, service development and monitoring and location of out-of-area placements.

Conclusion There is disparity in the extent to which the participating services have practices that are consistent with the quality indicators.
