What this trial studies

This study aims to validate the Dutch version of the TAPS-tool, which screens for substance use among patients. It will involve two groups: patients without intellectual disabilities receiving treatment from Flexible Assertive Community Treatment (FACT) teams and patients with intellectual disabilities, for whom an adjusted version of the tool will be developed. The outcomes from the TAPS-tool will be compared to a gold standard assessment to determine its reliability and validity. The study will take place in standardized care settings where patients are routinely assessed for various mental health and substance use issues.

Who should consider this trial

Good fit: Ideal candidates include patients treated in FACT teams or those with intellectual disabilities receiving care at the LVB-P department.

Not a fit: Patients who do not speak Dutch sufficiently or cannot concentrate for 20 minutes will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the screening and assessment of substance use issues in diverse patient populations, leading to better-targeted interventions.

How similar studies have performed: Other studies have shown success in validating screening tools for substance use, indicating that this approach is promising.
