Introduction:
This study investigated the reliability and validity of the dynamic risk outcome scales-short version (DROS-SV). This instrument is developed to monitor treatment progress using dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning and behavioural and/or mental health problems.
Method:
Data were collected from 264 clients who received Flexible Assertive Community Treatment (FACT), a form of intensive outpatient treatment.
Results:
A principal component analysis showed that there were six components explaining 73.9% of the variance. Furthermore, the DROS-SV showed good internal consistency of its subscales and total score (α > 0.78). Correlating the DROS-SV with the Historical and Clinical subscales of the Historical, Clinical and Future-30 indicated convergent and divergent validity.
Discussion:
The DROS-SV has good psychometric properties for measuring dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning in FACT teams.
