The Diabetes Time Management Questionnaire

Abstract

PURPOSE The purpose of this study was to test the psychometric properties of the 49-item Diabetes Time Management Questionnaire (DTMQ) in individuals with diabetes. The DTMQ was designed to assess general time management skills and those specifically relevant to compliance to a diabetes healthcare regimen. METHODS Participants completed the DTMQ; the Habits, Attitudes, and Knowledge Questionnaire of Diabetic Compliance (HAK); and the Diabetes Knowledge Schedule (DKS) to provide two indices of construct validity of the DTMQ. Three HAK items related to time management skills (HAK-TM) provided an index of concurrent criterion-related validity for the DTMQ. RESULTS Test-retest stability reliability results were significant for DTMQ total and individual item scores. Concurrent criterion-related validity of the DTMQ was supported by a significant correlation with the HAK-TM items. Construct validity of the DTMQ was partly supported by significant correlations with the DKS and two HAK items measuring diet and exercise compliance. CONCLUSIONS The results support the use of the DTMQ to assess the time management skills of individuals with diabetes.
