Reliability and validity of the dynamic risk outcome scales—short version for clients with mild intellectual disabilities or borderline intellectual functioning

Abstract

AbstractIntroductionThis 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.MethodData were collected from 264 clients who received Flexible Assertive Community Treatment (FACT), a form of intensive outpatient treatment.ResultsA 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.DiscussionThe DROS‐SV has good psychometric properties for measuring dynamic risk factors in clients with mild intellectual disabilities or borderline intellectual functioning in FACT teams.
