Using a sample of 348 middle school students, we gathered evidence regarding the internal consistency of scores, as well as the internal factor structure and convergent validity evidence for inferences from a self‐report questionnaire called the Self‐Regulation Strategy Inventory–Self Report. Confirmatory factor analysis revealed that the fit indexes for a hierarchical model (composite, three factors) and a single‐level, three‐factor model were highly similar but mixed. Respecification of the hierarchical model based on conceptual overlap of items led to substantial improvement in the overall fit of the model, as indicated by the root mean square error of approximation, chi‐square/ df , and the comparative fit index. Correlational analyses also provided strong convergent validity evidence, as the three subscales exhibited statistically significant relations with four motivation beliefs (i.e., self‐efficacy, perceived instrumentality, task interest, perceived responsibility) and two distinct markers of regulation‐related behaviors (i.e., teacher ratings, office discipline referrals).
