Abstract

Objective: The Adult Attention Deficit Hyperactivity Disorder (ADHD) Self-Report Scale (ASRS) allows dimensional self-rating assessment of ADHD according to DSM-IV. The Turkish version of the scale was validated in university students. The aim of the present study was to evaluate psychometric properties of the Turkish version of the ASRS in a sample of inpatients with alcohol use disorder (AUD).
Method: Participants included 190 inpatients with AUD. Participants were evaluated with the ASRS and the Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale (Adult ADHD Scale).
Results: The ASRS-18 (18 item version) was found to be a psychometrically sound adult ADHD screening measure with high convergent validity when compared with Adult ADHD Scale (r=0.738; 0.694 for inattentive-IN subscale and 0.690 for hyperactive/impulsive-HI subscale) and to have a Cronbach’s ? of 0.863 (0.822 for IN subscale and 0.775 for HI subscale). Two components accounted for 31.13% and 9.27% of total variance, respectively, for the ASRS-18. Subscales were highly correlated with total ASRS-18 score (n=190, r=0.887, r=0.886, respectively) and moderately correlated with each other (r=0.571). Test-retest correlation was moderate (n=120, r=0.677) for IN subscale whereas test-retest correlation was high for HI subscale (r=0.774) and for ASRS-18 (r=0.765). The ASRS-18 had sensitivity and specificity scores of 0.81 and 0.75, respectively, when using the optimal cut-off score of 30. Additionally, the ASRS-18 showed good discriminant validity as it significantly differentiated alcohol-dependent inpatients with a risk of ADHD from those without. The ASRS-6 (6 item version) showed psychometric properties similar to those of ASRS-18, although the sensitivity score (0.75) was lower than in ASRS-18, whereas the specificity score (0.79) was similar to ASRS-18, when using the optimal cut-off score of 10 for ASRS-6.
Conclusion: These findings confirm the Turkish version of the ASRS (both 18-item and 6-item versions) as a reliable and valid adult ADHD screening instrument that measures a two-dimension construct among inpatients with AUD.
