Modified Work Behavior Inventory assessment: Evaluation of psychometric properties

摘要

The Work Behavior Inventory (WBI) is a widely used and validated assessment of work functioning in people with schizophrenia. WBI ratings are based on workplace observation and interview with work supervisors. Workplace observation may not be acceptable in all employment settings. A WBI assessment based only on supervisor interview may offer more utility. The current study evaluated the psychometric properties of a modified WBI among individuals with schizophrenia participating in VA vocational rehabilitation programs – similar to the original WBI validation study. Results suggest evidence for reliability, validity and sensitivity to change for an interview only format. Limitations and future research directions are discussed.
