Objective To evaluate the effects of online group problem-solving therapy (PST) for reducing negative problem orientation (NPO), psychological distress, and increasing quality of life in patients with Cushing's disease (CD). Methods In this randomized trial, we allocated 55 eligible patients to either PST (n = 28) or treatment as usual (TAU) (n = 27) groups. The analyses primarily relied on intent-to-treat (ITT) principle and were repeated with intervention completers (per-protocol analyses). Social problem-solving inventory-revised short form, Beck Depression Inventory (BDI), General Health Questionnaire-12 (GHQ-12), Perceived Stress Scale (PSS), The Satisfaction with Life Scale, and Cushing's Quality of Life scale were used. Pre-test, post-test, and follow-up measures were obtained. Linear mixed models were used to compare PST and treatment as usual (TAU) groups across time. Results Of the total 55 patients with CD, the mean age was 46 +/- 12 years, 49 patients (89%) were female, and 41 patients (74.5%) were in remission. The patients within the PST and TAU groups were similar in terms of age, sex, and disease activity. ITT analyses showed a greater reduction of NPO scores in patients who received PST as compared to patients who received usual care (df = 45.9, p = 0.029, Cohen's d = 0.47). The decrease in NPO was sustained at follow-up (mean difference: - 2.2, p = 0.007). Results of the ITT analyses revealed no superior benefits of the intervention for psychological distress. However, per-protocol analyses demonstrated that PST provided a greater decrease in BDI, PSS, and GHQ-12 scores. Conclusion PST may decrease NPO and improve the psychological well-being of patients with CD.
