Validity of the Persian version of the Munich ChronoType Questionnaire (MCTQIR).

PURPOSE: Currently, the most useful questionnaire for determining the chronotype is the Munich ChronoType Questionnaire (MCTQ). It determines chronotype based on sleep-wake behavior on workdays and work-free days and uses the mid-sleep time on free days (MSF), corrected for accumulated sleep debt over the work week to classify chronotype (MSFsc). Our study aimed at validating Persian version of the MCTQ. METHODS: Participants completed the Persian version of the MCTQ, reduced Morningness-Eveningness Questionnaire (rMEQ), Epworth sleepiness scale (ESS), and demographic characteristics. RESULTS: The study sample was comprised of 250 Iranian men and women (mean age 34 years, age range 30 to 58 years, 113 men). Results showed that there is a significant negative relationship between the components of MCTQ and rMEQ, and the strongest relationship related to the MSF index. The results also showed that MCTQ parameters were not significantly related to the ESS scale. Cut-off values of MSFsc for chronotype categories were determined by inter-quartile range (Q25% = 3.44, Q50% = 4.68, and Q75% = 5.75). CONCLUSIONS: Like the MCTQ in other languages, the Persian version of the MCTQ is a reliable tool for assessing chronotype.

Investigating the role of attachment styles, dysfunctional attitudes, and spirituality in predicting membership in addicted and non-addicted groups.

Drug addiction as a biological, psychological, and social issue affects all dimensions of one's life. The purpose of this study was to determine the role of attachment styles, dysfunctional attitudes, and spirituality in predicting membership in addicted and non-addicted groups. This was a cross-sectional study conducted on 60 addicted people and 60 non-addicted people. The Adult Attachment Scale of Hazan and Shaver, Allport Religious Orientation Scale, and the 26-item Dysfunctional Attitude Scale (DAS-26) were used to measure the variables. Based on the results, which were analyzed by logistic regression analysis, the variables of attachment style and dysfunctional attitude can significantly predict drug addiction (p < .001). However, avoidant attachment style and spirituality cannot predict readiness for addiction. The results of this study indicate the importance of safe and ambivalent attachment styles and dysfunctional attitudes. Thus, attending to these factors in studies and interventions related to the treatment of substance abuse disorders is essential.

Treatment of premenstrual syndrome: Appraising the effectiveness of cognitive behavioral therapy in addition to calcium supplement plus vitamin D.

Premenstrual syndrome (PMS) consists of repetitious physical and psychological symptoms. The symptoms occur during the luteal phase of the menstrual period and cease when the menstrual period starts. This study included pre-test and post-test experiments between a control group and a test group. The statistical population involved 40 females, chosen based on multistage cluster sampling. The participants were then divided into four groups to undergo treatment with calcium supplement plus vitamin D together with cognitive behavioral therapy (CBT), and were screened with the Premenstrual Syndrome Screening Test (PSST). The pre-test and post-test scores in the PSST, the General Health Questionnaire (GHQ-28), and Bell's Adjustment Inventory (BAI) were used as assessment tools (p < .05). According to the parameters of PMS symptoms, when evaluating the pre-test and post-test scores, the overall score of each individual in the experimental group was improved and a significant effect for the combination of calcium supplement plus vitamin D together with CBT was observed in comparison to the post-test control group. A comparison of multivariate analysis of covariance (MANCOVA) results collected from the pre-test and post-test scores revealed that the method of treatment was beneficial for PMS, adjustment, and general health.
