The purpose of this paper is to present a critical analysis of the research methods in adapted physical activity studies about children with attention-deficit hyperactivity disorder (ADHD). The strengths and weaknesses of various research methods are discussed by (a) three main types of research questions, (b) identification and description of research participants, (c) reliability and validity of assessment instruments, (d) data collection procedures, and (e) quantitative and qualitative methods of data analysis. Strategies to improve research are embedded in each of the five main categories. It is concluded that substantial methodological inconsistencies exist in the current ADHD physical activity literature base. Future research would be strengthened by incorporating recommended suggestions.
