    Abstract

    METHODS: A cross-sectional study enrolled 200 children and adolescents with attention-deficit/hyperactivity disorder visiting four Chinese tertiary care psychiatric clinics to assess the validity and reliability of the Dundee difficult times of the day scale (D-DTODS), using the Weiss functional impairment rating scale for parents form (WFIRS-P) and the Swanson, Nolan and Pelham, version IV 26-item teacher and parent rating scale (SNAP-IV-26).

    RESULTS: The calculated Cronbach's-α for the D-DTODS total score was 0.793. The calculated Spearman's correlation coefficients for D-DTODS versus WFRIS-P and Swanson, Nolan and Pelham, version IV 26-item teacher and parent rating scale (SNAP-IV-26) were 0.425 (p < 0.01) and 0.452 (p < 0.001), respectively.

    CONCLUSION: The D-DTODS was worth future test-retest confirmation regarding reliability and validity for assessing functional impairment associated with attention-deficit/hyperactivity disorder across different time periods of the day in Chinese children and adolescents.
