A Study on the Validity and Reliability of the Turkish Translation of the Self-Report Wender-Reimherr Adult Attention Deficit Disorder Scale.

OBJECTIVES

Attention-Deficit/Hyperactivity Disorder (ADHD) in adults extends beyond inattention and impulsivity, encompassing challenges in emotion regulation and organization. This study aimed to evaluate the validity and reliability of the Turkish version of the Wender-Reimherr Self-Report Scale (SR-WRAADDS), developed based on the Utah Criteria for adult ADHD.

METHODS

The study included 172 adults diagnosed with ADHD and 92 healthy controls. Participants completed the SR-WRAADDS, Wender Utah Rating Scale (WURS), Adult ADHD Self-Report Scale (ASRS), and the Hospital Anxiety and Depression Scale (HADS).

RESULTS

The SR-WRAADDS total score was significantly higher in the ADHD group (p < 0.001). Factor analysis demonstrated a four-factor structure: attention deficit, emotional dysregulation, impulsivity/hyperactivity, and temperament, explaining 61.8% of the variance. Internal consistency was acceptable for all subscales (Cronbach's α = 0.67-0.86). SR-WRAADDS scores correlated positively with WURS and ASRS, but not with HADS subscales. Test-retest reliability ranged from moderate to strong.

CONCLUSION

The Turkish SR-WRAADDS is a valid and reliable self-report instrument that captures the multidimensional nature of adult ADHD, including emotional dysregulation. Its robust psychometric properties and diagnostic utility make it a powerful tool for both clinical practice and future research.
