Background: Peripheral neuropathy pain is common among adult diabetic patients worldwide. Lifestyle behavior modification such as proper diet and exercise, quitting smoking, weight control and regular follow up, as well as enhancement of self-efficacy among adult diabetic patients can be helpful in managing peripheral neuropathy pain and, therefore, improving their quality of life and satisfaction.Aims: This study aims to investigate educational self-efficacy enhancement program's impact on pain management, self-efficiency behaviors, quality of life and satisfaction among adult diabetic patients with peripheral neuropathy pain.Materials and Methods: This randomized controlled study was conducted between October and March 2020 at the Jordanian Ministry of Health settings, where 72 adult diabetic patients with peripheral neuropathy pain were randomly assigned into research group (n = 36) or control group (n = 36), after obtaining ethical approval and informed consents. An educational self-efficacy enhancement program was implemented in the research group only. The instrument used for data collection consisted of Demographic Data Form, Diabetes Pain Intensity Scale, Self-Efficacy Scale, Quality of Life Questionnaire (EQ-5D) and Patient Satisfaction Questionnaire.Results: Statistically significant improvements in pain levels (p = 0.020), self-efficacy score (p = 0.000), quality of life scores (p = 0.000) and best imagined health status (p = 0 .000) were found among research group participants. Furthermore, multiple-linear regression models showed that the implementation of educational self-efficacy enhancement program significantly increased the explained variance of self-efficacy scores (R2 = 0.746, p = 0.000) and quality of life scores (R2 = 0.746, p = 0.000). At the end of implementation, research group participants showed a high overall satisfaction levels (4.33 out of 5). Conclusion: The findings suggest that an educational self-efficacy enhancement program is effective in modifying adult diabetic patients’ lifestyle, enhancing self-efficacy behaviors, managing peripheral neuropathy pain, improving quality of life and satisfaction among adult diabetic patients. It is, therefore, recommended to expand the implementation of this program among adult diabetic patients with peripheral neuropathy pain.
