Health-Related Quality of Life In Kuwait: Validation of Generic and Disease-Specific Measures

Abstract

Chronic diseases such as diabetes have become increasingly prominent around the world. Diabetes care requires a combination of medication, exercise, diet, self-management education, and psychosocial care to reduce the risk of long-term complications. Following this strict regimen can have an adverse effect on the patient's quality of life. Quality of life is a broad concept that is difficult to define and study. This study focused on the health-related component of quality of life. Diabetes is reaching epidemic proportions in Kuwait. While the incidence of the disease is documented, little is known about its effect on the life of the Kuwaiti population. This is partly due to the lack of valid Arabic versions of health-related quality of life (HRQOL) instruments. The purpose of this study was to investigate the construct validity of two HRQOL measures in a sample of older adults in Kuwait with Type 2 diabetes. The two measures were the Short Form 36-Item Health Survey version 2.0, a generic measure, and the Problem Areas in Diabetes survey, a disease-specific measure. A total of 240 Kuwaiti citizens over the age of 55 years living in Kuwait City participated in this study. Participants were divided into two groups: the Diabetes Group included 120 older adults with diabetes and the Control Group included 120 older adults without diabetes. Three approaches were used to assess the construct validity of the Arabic versions of the SF-36v2 Health Survey and the Problem Areas in Diabetes survey: factor analysis, correlation, and known-group method. The results of this study support the use of the Arabic versions of the two surveys to measure HRQOL of older adults in Kuwait with Type 2 diabetes. Standards for construct validity were well met, with few exceptions.
