Objectives. In the present study the utility and psychometric properties of the Hungarian version of the Adult ADHD Self-Report Scale (ASRS-v1.1) was investigated. The purpose was to translate and to adapt the ASRS-v1.1 screener (6-item) and the Symptom Checklist (18-item). In addition, no previous studies assessed prevalence of ADHD symptoms of Hungarian adults from Romania.
Methods. A total of 1,503 adults were evaluated. The mean age of participants was M(SD)=23.98(57.26) years, between 18-44 years, 37.7% (N=567) were male participants, 69.4% from Romania (N=1,043) and 30.6% from Hungary (N=460). 100-100 participants from the positive and negative result group were randomly selected for confirming diagnosis.
Results. The CFA indicated adequate fit to the structure proposed by the DSM-IV in the 18-item version. The ASRS-v1.1 maintained its two-factor structure model of inattention (9 items) and hyperactivity/impulsivity (9 items). Furthermore, the subscales of the 18-item ASRS-v1.1 exhibited good internal consistency indicated by acceptable Cronbach’s alpha (inattention subscale α=.84, hyperactivity subscale α=.80, total α=.88). Reliability values of the ASRS-v1.1 screener were less adequate than the symptom checklist. According to the results, the 6 item ASRS-v1.1 had fair internal consistency (inattention subscale α=.77, hyperactivity subscale α=.54, total α=.72).
Unweighted prevalence of AD, based on the ASRS-v1.1 symptom checklist, was 1.5% (N=23). Moreover, 1.2% of the assessed population seems to have HD, mostly female participants (0.8%). In addition, 4.5% seems to have ADHD (N=67), mostly male (2.5%). The screener identified 37.3% (N=561) of the total assessed population as highly likely to have ADHD.
The Area Under Curve for the ASRS-v1.1 6 item was AUC=.99 (95% CI: .98-1.00), while for the 18 item ASRS-v1.1 was AUC=1.00.
Conclusions. Results suggest that the 18 item ASRS-v1.1 is a good symptom checklist for the assessment of adult ADHD, indicated by the good psychometric properties of the scale. In addition, the ASRS-v1.1 screener can be considered a fair screening tool for identifying symptoms of ADHD among normal population.
