Client Socio-Demographic and Service Receipt Inventory - European Version: Development of an instrument for international research - EPSILON Study 5

Background Cross-cultural comparison of mental health service utilisation and costs is complicated by the heterogeneity of service systems. For data to be locally meaningful yet internationally comparable, a carefully constructed approach to its collection is required. Aims To develop a research method and instrument for the collection of data on the service utilisation and related characteristics of people with mental disorders, as the basis for calculating the costs of care. Method Various approaches to the collection of service use data and key stages of instrument development were identified in order to select the most appropriate methods. Results Based on previous work, and following translation and cross-cultural validation, an instrument was developed. the Client Socio-Demographic and Service Receipt inventory - European Version (CSSRI - EU). This was subsequently administered to 404 people with schizophrenia across five countries. Conclusion The CSSRI-EU provides a standardised yet adaptable method For collating service receipt and associated data alongside assessment of patient outcomes. Declaration of interest of interest.
