Abstract

PURPOSE:

This cross-sectional, correlational study examined the relationships of diabetes-specific treatment barriers and self-efficacy with self-care behaviors.

METHODS:

A total of 309 people with type 2 diabetes participated in this study. All of the factors were assessed by self-report questionnaires. Self-care behaviors included exercise, diet, skipping medication, testing blood for glucose, adjusting insulin to avoid or correct hyperglycemia, and adjusting diet to avoid or correct hypoglycemia.

RESULTS:

Perceived barriers to carrying out self-care behaviors were associated with worse diet and exercise behavior. Greater self-efficacy predicted more frequent blood glucose testing, less frequent skipping of medication and binge eating, and closer adherence to an ideal diet. Nontraditional dimensions of self-efficacy were associated with worse self-care. Self-efficacy explained 4% to 10% of the variance in diabetes self-care behaviors beyond that accounted for by patient characteristics and health beliefs about barriers.

CONCLUSIONS:

The findings of this study provided support for Rosenstock's proposal that a person's self-perceived capability to carry out a behavior should be incorporated into an expanded health belief model.
