Problem Solving Inventory (PSI)

This chapter is a comprehensive reference manual providing information on the Problem Solving Inventory, which is a self-rating scale, designed to measure “an individual’s perceptions of his or her own problemsolving behaviours and attitudes”. It was developed for the general population, but has also been used with people with stroke and traumatic brain injury. A brief history of the instrument's development is provided, along with a description of item content and administration/scoring procedures. Psychometric properties are reviewed and a critical commentary is provided. Key references are cited and in most cases the actual scale is included, giving the reader easy access to the instrument.
