Introduction: Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder in children and adolescents. Reliable and culturally appropriate assessment tools are crucial for accurate diagnosis and management. This study aimed to adapt and validate the ADHD Rating Scale-5 (Parent Version) into Bangla, assessing its psychometric properties in a Bangladeshi context. Methods: This cross-sectional study was conducted with 100 participants from urban areas and nuclear families. The scale underwent a rigorous translation and cultural adaptation process, following a six-step methodological approach. The study evaluated the scale's internal consistency, content validity, and construct validity through Cronbach's alpha, Content Validity Index (CVI), and factor analysis, respectively. Result: The ADHD-RS-5 Bangla Parent Version demonstrated high internal consistency (Cronbach’s alpha = 0.89) and good reliability in the Inattention (alpha = 0.858) and Hyperactivity-Impulsivity (alpha = 0.818) subdomains. Content validity was confirmed with high Item-CVI scores and a Scale-level CVI of 0.962. Confirmatory factor analysis supported the two-factor structure of the scale, and exploratory factor analysis identified three components, explaining 71.1% of the variance. Conclusion: The ADHD-RS-5 Bangla Parent Version is a reliable and valid tool for assessing ADHD symptoms in Bangla-speaking children. Its strong psychometric properties make it suitable for clinical and research use in Bangladesh. This study contributes to the development of culturally sensitive assessment tools for ADHD, enhancing the understanding and management of the disorder in diverse populations.
