Background: Marital adjustment is a state among couples in which there is an overall feeling of happiness and satisfaction with their marriage and each other. But how important could the role of two factors of metacognitive beliefs and the mediating effect of marital conflicts in marital adjustment be. Aims: The purpose of this study was to predict marital adjustment based on meta-cognitive beliefs and mediating role of marital conflicts in married students. Method: The research method is a descriptive and correlational design and structural equation modeling method. The statistical population in this study was all married students studying at Azad University of Tehran branches who had criteria for entering the research. The sample size was 400 people, 200 married women and 200 married men who were determined according to sample size estimation in research based on structural equation modeling. The measurement tools consisted of the Spanier modified marital adjustment questionnaire (1976), Wales meta-cognitive beliefs questionnaire (1997), and Barati and Sanyi marital conflicts questionnaires(1999). Results: The results of the measurement model showed that subscales of research all have significant factor loadings. Also, model fitting indicators after covariance between some markers of metacognitive beliefs and marital conflicts were in desirable condition. The results of the hypothesis test showed that metacognitive beliefs on the marital adjustment of married students have indirect effects (due to marital conflicts) (p<0.05). Marital conflicts directly affect marital adjustment(p<0.05).  According to the results of the study, marital conflicts have a mediator role in predicting the marital adjustment of married students(p<0.05).  Conclusions: On one hand, marital conflicts are influenced by metacognitive beliefs and on the other hand they can have significant effects on marital adjustment.

 Background: Although distress tolerance plays a significant role in mental and physical health, developing specific interventions regarding an increase in distress tolerance has rarely been paid attention to. The impacts of the compassion-based intervention on psychological features of individuals with psychosomatic conditions have been rarely examined as well. Aims: The goals of the present study were, first, to introduce the distress tolerance promotion package (DTPP) and, second, to compare its effectiveness with compassion-focused therapy (CFT; Gilbert, 2010) in terms of self-criticism, fear of negative evaluation, and anxiety in women with chronic tension-type headaches. Method: The research was quasi-experimental with the pretest, posttest, and control group design. The statistical population included all women with tension-type headaches referred to headache and neurology clinics in Isfahan in 2019. Forty-eight women with tension-type headaches using purposeful sampling method were selected and randomly assigned to DTPP (n=16), CFT (n=16), and control (n=16) groups. DTPP and CFT groups attended a 90-minute session per week for 8 weeks, whereas the control group received no particular intervention. The participants were assessed using the scales of self-criticism (Gilbert et al., 2004), the fear of negative evaluation (Leary, 1983), and anxiety (Beck et al., 1998) in the pretest and posttest stages. Results: The MANCOVA results revealed that compared to the control group, DTPP and CFT groups lead to significant improvements in each of the scales of self-criticism, the fear of negative evaluation, and anxiety in the women with tension-type headaches. DTPP was also shown to have a greater positive effect on the reduction of self-criticism compared to CFT. Conclusions: Based on the findings, the effectiveness of the newly designed distress tolerance promotion package and compassion-focused therapy were approved on self-criticism, fear of negative evaluation, and anxiety in women with chronic tension-type headaches.
