Psychometric Findings for a Spanish Translation of the Diabetes Self-Management Profile (DSMP-Parent-Sp)

Few validated measures exist to evaluate self-management of diabetes in families with limited English proficiency. The present study evaluated the psychometric properties and the factorial equivalence of a Spanish translation of the parent report version of the Diabetes Self-Management Profile (DSMP-Parent-Sp). Hispanic families of youth (mean 13.7 years old) with type 1 diabetes were recruited from three clinics in South Florida and represented a wide range of nationalities and acculturation levels. A total of 127 parents reported on their child's self-management behaviors using either the original DSMP-Parent (59.8%) or the DSMP-Parent-Sp (40.2%). In addition, youth reported their self-management using the original DSMP in English, and physicians rated their perceptions of the youth's self-management. Glycemic control was indexed by A1C in the past 3 months and collected from medical chart review. Item analysis confirmed that the DSMP-Parent-Sp items related to the overall composite score in expected ways, and internal consistency estimates were adequate. Paired correlations demonstrated strong parent-child concordance and a significant relationship with physician perceptions of self-management. Evidence of concurrent and convergent validity, as well as "strict factorial invariance," was demonstrated. These preliminary findings indicate that the DSMP-Parent-Sp is a reliable and valid parent report measure of the diabetes self-management behaviors of Hispanic youths. In addition, there is preliminary evidence that the translated measure may be considered equivalent to the original English measure when used to measure self-management in Hispanic youth with diabetes

Diabetes Problem Solving by Youths with Type 1 Diabetes and their Caregivers: Measurement, Validation, and Longitudinal Associations with Glycemic Control

Objectives This article introduces a new measure of problem-solving skills of youths with type 1 diabetes (T1DM) and adult caregivers in correcting glycemic fluctuations. Methods The Diabetes Problem Solving Interview (DPSI), a structured interview, was validated during a pilot study of a behavioral intervention. DPSI data and measures of diabetes management were obtained at baseline from 114 youths (ages 9–14.5) and 109 caregivers. Glycosylated hemoglobin (HbA1c) was measured quarterly over 9 months. Results Results confirmed the psychometric adequacy of the DPSI. For caregivers, but not youths, low DPSI scores (indicating poor problem-solving skills) were significantly associated with worse HbA1c over 9 months. Conclusions The DPSI has clinical and research utility as a measure of diabetes problem-solving skills. Identification and targeted remediation of caregivers’ deficient diabetes problem-solving skills or promotion of youths’ utilization of these skills could possibly enhance glycemic control in youths with T1DM
