Psychometric properties of the revised Parental Monitoring of Diabetes Care questionnaire in adolescents with type 1 diabetes.
OBJECTIVE
We evaluated the psychometric properties of a revised version of the Parental Monitoring of Diabetes Care questionnaire (PMDC-R) designed to evaluate parental supervision and monitoring of adolescent diabetes care behaviors. The revised measure was intended to capture a broad range of ways used by parents to gather information about youth adherence to diabetes care.


METHODS
Two hundred sixty-seven caregivers of 12-18-year-old adolescents with type 1 diabetes completed the PMDC-R. Measures of parental knowledge of youth illness management, illness management behavior, and metabolic control were also obtained.


RESULTS
The PMDC-R demonstrated good internal consistency (alpha coefficient = .91) and test-retest reliability (r = .79, p < .001). Supporting the instrument's construct validity, a bifactor model with one primary factor and three secondary factors had an acceptable fit to the data (comparative fit index = .92, root mean square error of approximation = .06). Concurrent validity was also supported. In structural equation models, parental monitoring, as assessed by the PMDC-R, had a significant direct effect on parental knowledge of adolescent diabetes management and, through knowledge, an indirect effect on adolescent diabetes management and metabolic control.


CONCLUSIONS
The PMDC-R displayed strong psychometric properties and represents an important next step in refining the measurement of parental monitoring for youth with chronic illnesses.
