The Diabetes Symptom Self-Care Inventory: Development and Psychometric Testing with Mexican Americans

Context. Type 2 diabetes is prevalent throughout the world. In previous studies of Mexican Americans with type 2 diabetes, 95%-97% of those sampled reported having symptoms they believe were caused by diabetes and most self-treated their symptoms. To more accurately capture Mexican Americans' symptom prevalence and their self-treatments, the Diabetes Symptom Self-Care Inventory (DSSCI) was adapted from the Diabetes Self-Care Instrument. Objectives. This article describes the modification process used to perfect the DSSCI for use in improving self-care among people with type 2 diabetes. Methods. This instrumentation study used qualitative and quantitative methods. The study was completed in four phases that used focus groups, cognitive interviews, and survey administration. Four convenience samples were drawn from community-dwelling Mexican American adults, aged 25-75 years, with type 2 diabetes in an urban area and a rural location in Texas.
