Abstract

Background

Adhering to clinical prescriptions is known to protect against the effects of uncontrolled hypertension and of acute and chronic cardiovascular diseases, including diabetes. Contextually, positive associations between self-care behaviors and psychological constructs, such as self-efficacy, are widely acknowledged in the literature. However, still little is known about the psychological factors underlying the patient’s self-efficacy. This study aimed to investigate the psychosocial and behavioral correlates of self-efficacy related to treatment adherence in older patients with comorbid hypertension and type 2 diabetes mellitus.

Participants and procedure

Italian and Polish patients (≥ 65 years; N = 180) consecutively responded to self-report questionnaires measuring psychosocial (i.e., beliefs about medicines, perceived physician’s communication effectiveness, medication-specific social support, self-efficacy) and behavioral factors (i.e., pharmacological adherence, medications refill adherence, intentional non-adherence) related to treatment adherence. Betweengroup comparisons and regression analyses were performed.

Results

Fisher’s least significant difference (LSD) test showed significant differences between the Italian and Polish groups in all questionnaires (p < .01) with the Italian patients reporting more satisfactory scores. Younger age (β = .08, p = .045), female gender (β = 1.03, p = .042), higher medication refills adherence (β = –.07, p = .024), lower intentional non-adherence (β = –.03, p = .009), positive beliefs about medications (β = .13, p < .001), better quality of communication with the physician (β = .09, p < .001), and stronger perceived medication-specific social support (β = .06, p = .001) were significantly associated with self-efficacy related to treatment adherence.

Conclusions

Future research and interventions should leverage psychosocial and behavioral factors to address self-efficacy contributing to enhancing adherence to clinical prescriptions.
