Occupational therapy practitioners and other clinicians understand the importance of accurately evaluating a client’s ability to accomplish necessary everyday tasks, especially those in the community setting. The Test of Grocery Shopping Skills is a new performance-based assessment that measures how accurately and efficiently clients can locate items in a grocery store. Developed primarily to assess individuals with serious mental illness, this assessment also is ideal for use with other populations in which cognitive impairments could interfere with community living skills, such as persons with brain injury, stroke, dementia, or developmental disabilities. The manual clearly discusses how to administer the test and to score and interpret results. Two different but statistically comparable pre- and post-test forms allow practitioners to measure changes in clients’ abilities. This user-friendly assessment also includes instructions for the test administrator and test taker, score sheets, grocery lists, and a sample store map and answer sheet—all of which are available on the enclosed CD-ROM for easy use with clients and also in the classroom.
