OBJECTIVE: To describe the predictive relationships of selected sociodemographic, biomedical, and psychosocial variables to reluctance to use insulin among patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS: A total of 178 patients with type 2 diabetes participated in this cross-sectional, observational study. Data were obtained by patient interview using validated measures of diabetes attitude, knowledge, self-efficacy, care communication, and perceived barriers to treatment, as well as sociodemographic and biomedical data.

RESULTS: Women and ethnic minorities with type 2 diabetes have more psychological barriers to insulin treatment (P < 0.05). The final regression model showed that individuals who believed in the value of tight glucose control, had strong self-efficacy, and had better interpersonal processes with their healthcare providers were less reluctant to use insulin treatment (R(2) = 0.403; P < 0.0001).

CONCLUSIONS: Diabetes self-efficacy and better interaction with clinicians were important in decreasing patients' reluctance to use insulin, known as psychological insulin resistance.
