Mental health service provision of adults with intellectual disabilities (ID) is often criticized. There is a lack of empirically studies targeting the psychotropic and psychotherapeutic treatment in this population. The PROMPT-ID study therefore aims to assess the prevalence of psychotropic medication and psychotherapeutic treatment in adults with mild to profound ID and the quality of psychotropic medication. It further aims to identify predictors of psychotropic medication, of barriers into psychotherapeutic treatment and of good clinical psychotropic medication prescription practice. It is a cross-sectional, epidemiological study carried out in Saxony, Germany. Approval of the responsible ethics committee was obtained. The inclusion criteria are mild to profound forms of ID and an age of 18 years or older. A representative sample is realized by a two-stage sampling procedure. Sheltered working and accommodation service providers are stratified by type of service provider and workshop size/type of accommodation. The stratified cluster sampling is realized by a random selection of service providing institutions followed by a random selection of adults with ID. An estimated total number of n = 200 study participants via sheltered workshops and n = 400 via residential accommodations need to be contacted to obtain data of approximately n = 131 study participants recruited through sheltered workshops and n = 232 participants through sheltered living institutions. Based on a psychotropic medication prevalence of 30%, in- depth interviews about psychotropic prescription practice of an estimated number of n = 109 adults with ID are carried out. Data collection is realized in interviews with key carers in the living environment and, if applicable, with the prescribing physician. If the adults with ID are currently medicated with psychotropics, basic information e.g. about kind, agent, dosage and treatment duration are obtained and a newly developed interview targeting the quality of the psychotropic medication treatment is conducted with the carers. In addition to the prevalence and quality of psychotropic and psychotherapeutic health care utilisation, other parameters like psychiatric symptomatology, problem behavior, sociodemografic and institutional factors and parameters of the provision area are assessed using well- established instruments. Findings will fill the lack of representative data that is urgently needed in this often criticized health service area.
