OBJECTIVE - The purpose of this study is to evaluate two updated measures of diabetes regimen adherence. The Diabetes Self-Management Profile (DSMP) is a widely used, structured interview. Limitations include a substantial interviewer and respondent time burden and the need for well-trained interviewers to use appropriate prompts and score the open-ended responses. The Diabetes Behavior Rating Scale (DBRS) is a self-administered, fixed-choice survey. RESEARCH DESIGN AND METHODS - Both measures were administered to 146 youth with type 1 diabetes (aged 11-18 years) and their parents. Items were added to the DBRS to allow for both flexible and conventional regimens, and the DSMP was modified to use standardized wording across items, accommodate flexible regimens, and permit administration by nonmedical interviewers. RESULTS - Both measures had good evidence of internal consistency (for the DSMP: parent 0.75 and youth 0.70; for the DBRS: parent 0.84 and youth 0.84). Scores on the DSMP and the DBRS were significantly related (r = 0.72 for parents and 0.74 for youth). There was moderate agreement between parent and youth (DSMP, r = 0.51; DBRS, r = 0.48). The measures were correlated with HbA1c for both parent (DSMP, r = -0.35; DBRS, r = -0.35) and youth (DSMP, r = -0.36; DBRS, r = -0.34) reports. CONCLUSIONS - Both measures exhibit good psychometric properties and good criterion validity but varied in terms of respondent and interviewer burden, issues that should be considered in selecting assessment procedures.
