It has been suggested that both internal (e.g., acceptability) and external (e.g., feasibility) factors should be taken under consideration in order to fully understand children's usage of interventions designed to improve their behavior. The purpose of this study was to initiate development of a student self-report measure (Children's Usage Rating Profile; CURP) designed to measure such factors. Results indicated that the CURP measures three interconnected aspects of students' perceptions of intervention: personal desirability, understanding, and feasibility. Furthermore, internal reliability analyses suggested that a measure consisting of 23 items may provide a reliable index of these three factors. Although these findings must be replicated across student populations and intervention types, results of the investigation suggest implications for researchers and practitioners interested in issues of intervention usage with children.
