Objective: The primary aim of this study was to evaluate the validity
and reliability of the Turkish version of the Wender-Reimherr Adult
Attention Deficit Disorder Scale (WRAADDS).
Method: The study included 146 individuals diagnosed with attentiondeficit/
hyperactivity disorder (ADHD) and 86 healthy controls (ADHD
group: age=24.46±5.82; control group: age=24.91±2.21). In addition to
the WRAADDS, the Adult ADD/ADHD DSM-IV-Based Diagnostic
and Assessment Scale, the Wender Utah Rating Scale (WURS), and
the Hospital Anxiety and Depression Scale (HADS) were administered.
Results: The ADHD group showed significantly higher total and
subscale scores on the WRAADDS compared to the control group (p
<0.001). Confirmatory factor analysis indicated that the original model
demonstrated good fit (χ²=34.392, df=13, p=0.001). Under Factor
1, the dimensions of inattention and disorganization were included,
whereas hyperactivity/restlessness, temper, affective lability, emotional
overreactivity, and impulsivity were included under Factor 2. In the
internal consistency analysis, Cronbach’s alpha coefficients were 0.97
for Factor 1 and 0.59 for Factor 2, respectively. The WRAADDS total
score showed significant positive correlations with the total scores of
other ADHD scales (p <0.01). No significant correlations were found
between WRAADDS total score and the anxiety or depression subscales
of the HADS (p>0.05).
Conclusion: The Turkish version of the WRAADDS is a
psychometrically valid and reliable instrument that comprehensively
assesses adult ADHD.
