Because of the recency of the large numbers of youth diagnosed with type 2 diabetes (T2D), measures of adherence behavior and family response to diabetes have not been developed or tested.


The objective of this study is to identify whether questionnaires on personal and family behaviors regarding the care of diabetes previously used with youth with type 1 diabetes (T1D) are reliable and related to metabolic control among youth with T2D.


During a regularly scheduled visit, youth with T2D and a parent/guardian were invited to participate in the study. Youth and a parent completed questionnaires and one 24-h dietary recall at the visit. During the following 2 wk, each youth completed two telephone dietary recalls and physical activity questionnaires.


Child-reported scales measuring parental reminding, positive family behavior, self-care behaviors, and self-efficacy and maternal report of child self-care behaviors and maternal self-efficacy were found to have adequate internal consistency. Only parental reminding was related to metabolic control. Those youth reporting higher parental reminding were in poorer metabolic control.


These scales appear to be reliable with youth with T2D in south Texas.
