Preliminary psychometric characteristics of the Serbian adaptation of the Adult ADHD Self-Report Scale: ASRS-v1.1 and ASRS-5
Abstract
The aim of the research is to explore the psychometric characteristics of the Serbian adaptation of the Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist and Screener, as well as the Adult ADHD Self-Report Screening Scale for DSM-5 (ASRS-5). In addition to these scales, the Depression Anxiety Stress Scale-21 (DASS-21), Dickman Impulsivity Inventory (DII) and the questions about frequency of risky behaviours (use of alcohol, cigarettes and drugs, overeating, and physical aggression) were administrated on the sample of 226 adults from the general population (43.8% males). The results of confirmatory factor analysis supported the one-factor structure of the ASRS-5. The three-factor structure had the best fit indices for the ASRS-v1.1 Symptom Checklist (inattention, hyperactivity, and impulsivity factors), while the two-factor structure was the best for the ASRS-v1.1 Screener (inattention and hyperactivity factors). However, there was a large profile similarity between factors, which calls into question their discriminant validity. All scales correlated significantly with dysfunctional impulsivity and aspects of psychological distress, with ASRS-5 having the largest number of correlations with risky behaviours. There were no sex differences, and correlations with age were negative. It can be concluded that, although all scales show satisfactory psychometric characteristics, ASRS-5 is the preferred one, given its clear one-dimensional structure and somewhat better validity.
