Abstract
Background & Aim: This study aimed at comparing efficacy of cognitive behavioral therapy, Zolpidem 10 mg, and waiting list group on illness perception and sleep efficiency in individuals with chronic insomnia disorder.
Materials & Methods: Participants included 74 (female = 43) individuals with chronic insomnia disorder who were recruited from 2018 December to 2020 February by purposive sampling (inclusive & exclusive criteria). Then, patients randomly allocated to one of the three conditions, including cognitive behavioral therapy (N=25), pharmacotherapy (Zolpidem 10 mg.; N=29), and the waiting list (N=20). All patients were assessed three times at pretreatment, post-treatment, and 3-month follow-up by the Persian version of Brief Illness Perception Questionnaire and Sleep Efficiency Index. The data were analyzed by mixed analysis of variance with Bonferroni post-hoc test and repeated measure analysis of variance.
Ethical Considerations: All stages of the research have been carried after taking supervising and approving of Kharazmi University's ethics in research committee.
Findings: The patients who received cognitive behavioral therapy compared to patients in waiting list group, obtained significantly lower scores in illness perception and sleep efficiency during post-treatment and 3-month follow-up. Efficacy of pharmacotherapy only observed during post-treatment but there were no significant differences between pharmacotherapy and waiting list patients during 3-month follow-up.
Conclusion: Cognitive behavioral therapy for insomnia reduced significantly illness perceptions and sleep efficiency during 3 months. All the treatment gains remain stable even 3 months later treatment ends. In addition, not receiving any treatment in waiting list and gradually discontinued the treatment in pharmacotherapy group leads to decreasing of sleep efficiency and increasing of illness perception.

Abstract
Introduction: Sleep quality is one of the effective variables in other psychological characteristics, especially in multiple sclerosis patients. As a result, the present study was conducted with the aim of determine the role of interpersonal problems and illness perception in predicting sleep quality with mediating distress tolerance in multiple sclerosis patients.
Methods: This was a cross-sectional correlational study. The research population was all patients who were members of the Multiple Sclerosis Association of Urmia township in the first quarter of 2021 year. The sample size was estimated 315 people who were selected by available sampling method. The research data were collected by Barkham et all short version of interpersonal problems inventory (1996), Broadbent et all brief illness perception questionnaire (2006), Buysse et all Pittsburgh sleep quality index (1989) and Simons & Gaher distress tolerance scale (2005) and were analyzed by Pearson correlation coefficients and path analysis methods in SPSS-19 and PLS-3 software. This research with the IR.IAU.URMIA.REC.1400.022 ethics code is approved by the ethics committee in biomedical research of Islamic Azad University of Urmia branch.
Results: The results showed that the increase of interpersonal problems and negative perception of illness led to decrease the distress tolerance and loss of sleep quality and an increase of distress tolerance improved sleep quality. In addition, the decrease of interpersonal problems and negative perception of illness with mediating distress tolerance led to improved sleep quality (P<0.01).
Conclusions: According to the results, to improve the sleep quality of multiple sclerosis patients can be increased the rate of their interpersonal problems and illness perception and decreased their distress tolerance.
