The purpose of the Time-Out Parent Inventory (TOPI) is to provide an objective and quantitative assessment of a parent's self-reported use of time-out procedures to manage a child's behavior. The TOPI is intended to be a tool for researchers as well as professionals who help parents and children. The professional asks the parent a series of 12 questions that provide an assessment of the parent's skill in following the time-out procedures described in "SOS! Help for Parents" (Clark, 1985). Content validity and interrater reliability have been demonstrated in studies involving 20 parents. Advice is given about TOPI administration and scoring and how to give feedback to parents. The inventory is attached. Three figures illustrate the discussion. (Contains 13 references.) (SLD)
