Participation restrictions in substance use disorders. Registration by screening and assessment instruments

Substance use disorders can contribute to severe participation restrictions. Whether these participation restrictions are covered by assessment instruments that are frequently used in addiction treatment services is not known. The international Classification of Functioning, Disability and Health (ICF) provides a framework to compare the content of different assessments. The aim of this study was to investigate whether assessments that are frequently used in German addiction treatment services, cover participation restrictions according to the ICF. In the summer of 2015, we asked German addiction treatment services to participate in an online survey. Addiction treatment services were approached via the mailing lists of German associations of addiction treatment. Respondents were asked to indicate which assessments from a list of frequently used assessment instruments they were using in their treatment service. The most frequently used assessments were then linked to components of the ICF. A total of N = 177 addiction treatment services responded to the survey. Most of them offered long-term rehabilitation treatment (n = 97; 61 %) or counselling services (n = 44; 28 %). Twelve assessments were used by more than 10 % of the respondents. The analysis revealed a total of 491 so-called meaningful concepts that could be linked to components of the ICF. Of these, 95 (16 %) referred to the ICF component activity and participation. Frequently used assessments in addiction treatment services include contents of the ICF component activity and participation to a substantial degree. However, this does not mean by default that these assessments can be used to assess participation restriction in a meaningful way.
