- Abstract
<bold>Objective: </bold>Children with ADHD frequently manifest behavioral difficulties in the morning prior to school. We sought to assess the reliability and validity of the Before-School Functioning Questionnaire (BSFQ) as a measure of morning behaviors impaired by ADHD.<bold>Method: </bold>We used pre-treatment data from a randomized crossover study of 6- to 12-year-old participants comparing the methylphenidate transdermal delivery system (MTS) with a placebo transdermal system (PTS) for a total of 4 weeks.<bold>Results: </bold>The BSFQ investigator-rated scale shows very good internal homogeneity (Cronbach's α = .91), good test-retest reliability ( r = .60), good concurrent validity ( r range = .42-.86), and a strong treatment effect (effect size = -.93). The self-rated BSFQ showed lower levels of reliability and validity.<bold>Conclusion: </bold>The investigator-rated BSFQ should be used in future trials of ADHD medications aimed at assessing efficacy in the morning before school.
