The purpose of this study was to develop and provide an initial examination of a self-report measure of intervention usage called the Usage Rating Profile-Intervention (URP-I). From an initial pool of 55 items, results of exploratory factor analysis and reliability estimates supported a measure containing 35 items and four factors as relevant toward understanding intervention usage. Those factors were labeled "acceptability", "understanding", "feasibility", and "systems support". Limitations and future directions are discussed. (Contains 5 tables.)
