All FACT teams in the participating organization (GGZ Oost Brabant) work through a standardized care pattern which implicates screening and assessment on several areas. At the start of the treatment all patients are assessed for intellectual disabilities, trauma related symptoms, addiction, quality of life, level of psychiatric complaints, social functioning, and phase of recovery. Subsequently quality of life and the level of psychiatric complaints is measured yearly. For this research question a small golden standard instrument was added to the standard screening and assessment.~For people with intellectual disabilities (ID) who get an extensive assessment of substance use problems in their (standard) treatment, permission to participate on the TAPS (version for ID) was asked.
The aim of the study is to investigate the reliability and validity of the Dutch version of the TAPS-tool.~This will be investigated in 2 groups: patients without intellectual disabilities treated in Flexible Assertive Community Treatment (FACT) teams and patients with intellectual disabilities. For the later group, an adjusted version of the TAPS-tool will be developed.~For both groups the TAPS outcome will be compared to a golden standard.
