This study aimed to compare the effectiveness of emotion regulation training and problem-solving skills training on self-care behaviors in patients with diabetic nephropathy.<br> <b>Methods</b>: This quasi-experimental study employed a pretest&ndash;posttest design with a three-month follow-up and a control group. The study population consisted of patients with diabetic nephropathy who referred to the IRIB Health Center in Tehran in 2024. Forty-five eligible participants were randomly assigned to three groups: emotion regulation training (n = 15), problem-solving skills training (n = 15), and a control group (n = 15). Self-care behaviors were assessed using the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire. Data were analyzed using repeated-measures ANOVA with the Greenhouse&ndash;Geisser correction.<br> <b>Results</b>: Both intervention groups showed significant improvements in overall self-care and in dietary adherence, blood glucose monitoring, medication adherence, and foot care at posttest and follow-up (P < 0.001). No significant differences were found between groups or over time for physical activity (P > 0.05). Comparative analyses revealed that problem-solving skills training was more effective and demonstrated greater durability than emotion regulation training in executive self-care components, particularly dietary adherence and foot care (P < 0.001).<br> <b>Conclusions</b>: While emotion regulation training supports psychological adjustment to chronic illness, problem-solving skills training offers more structured and action-oriented strategies for effective disease management. Incorporating problem-solving&ndash;based interventions into diabetes care programs is therefore recommended.</span></span></span></span></p> Diabetic nephropathy, Self-care, Emotion regulation, Problem-solving skills, Disease management 0 0 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-1141-1&slc_lang=en&sid=1 Laleh Rezaei 0523744001@iau.ir 100319475328460012015 100319475328460012015 No Department of Psychology, Central Tehran Branch, Islamic Azad University, Tehran, Iran Susan Emamipour Susan.emameipour@ac.ir 100319475328460012016 100319475328460012016 Yes Department of Psychology, Central Tehran Branch, Islamic Azad University, Tehran, Iran Mojgan Sepah Mansour drsepah-mansour@iau.ir 100319475328460012017 100319475328460012017 No Department of Psychology, Central Tehran Branch, Islamic Azad University, Tehran, Iran
