Self-Efficacy Effects of Maccabi Telcare Center Diabetes Mellitus Intervention: Do Men and Women Benefit Equally?

Background and purpose: A growing body of evidence points to physiological and psychological gender differences in the manifestation and treatment of type 2 diabetes mellitus. This study is part of a large-scale, prospective trial investigating the effects of Maccabi Telecare Center (MTC) interventions on self-efficacy. Here, we focus on the effects of gender on diabetes self-efficacy related to depressive symptom severity and illness representation.

Methods: A prospective open-label study investigating the effect of tele-based intervention on diabetes self-efficacy. Participants completed the following questionnaires: Diabetes Management Self-Efficacy Scale (DMSES) (self-efficacy), Patient Health Questionnaire 9 (PHQ-9) (depression), and Illness Perception Questionnaire-Revised (IPQ-R) (illness representation). Data were collected at three time points: Baseline (T1), 3-4 months (T2), and 8-9 months (T3).

Results: Although men and women exhibited similar baseline self-efficacy levels, men scored significantly higher than women over time, at T2 (p < .05) and T3 (p < .05). Consistent gender differences were observed throughout the study in depression and illness representations: women scored higher than men on PHQ-9 (3.94 vs. 5.57, p < .001), and perceived their diabetes consequences as more severe than men (p < .001). A linear regression analyses indicated that MTC intervention, age, baseline self-efficacy, and depression at T3 explained 39.8% of the variance of selfefficacy at the conclusion of the study for both genders, although more strongly for men.

Implications for practice: This study indicates that the effects of a treatment intervention for individuals with type 2 diabetes mellitus are gender specific. Thus, gender-tailored interventions may be advised to further improve outcomes for women with type 2 diabetes mellitus.
