Introduction: Menstrual distress caused by primary dysmenorrhea is associated with physical and psychological symptoms-before, after, and during menstruation. Leventhal's self-regulation educational model is based on the cognitive and emotional experiences of threat responses to symptoms and relates to coping responses. This study aims to investigate the effect of the implementation of a psychoeducational intervention, based on the selfregulation model of menstrual distress in adolescents. Methods/design: In this randomized controlled trial, 120 adolescent girls with moderate to severe menstrual pain (based on visual analog scale (VAS) ≥ 4) from twelve randomly selected high schools in Qazvin City will be enrolled in the study and will be randomly assigned to either a 3-session psychoeducational intervention (n = 60) or control (n = 60) groups. The sessions will be between 60 and 90 min apiece, and they will run for three consecutive weeks (one session per week). The data collection tools will include questionnaire eliciting menstrual information and demographics, the VAS, the Moos Menstrual Distress Questionnaire, and the illness perception questionnaire. One month prior to the intervention, both groups will participate in an initial assessment to assess the severity of their pain and level of menstrual distress. Finally, all questionnaires will be completed for three consecutive months after the intervention is completed. Discussion: It is anticipated that findings of this study will provide evidence for the effectiveness of the Leventhal self-regulation model. Implications for improved practice, understanding, and treatment for menstrual distress may also arise.

INTRODUCTION: The present study aimed to investigate the mediating role of Islamic work ethic in the relationship between spiritual intelligence and occupational self-efficacy in the Red Crescent relief workers. METHODS: This applied research was conducted based on a descriptive-survey design. The statistical population consisted of all Red Crescent relief workers in Torbat Heydariyeh, Iran (n=146). In total, 106 relief workers were selected using simple random sampling and the required data were collected through standard questionnaires. Finally, the collected data were analyzed in SPSS (version?) and Smart PLS software (version?). FINDINGS: Based on the results, there is a significant positive relationship between spiritual intelligence and occupational self-efficacy of Red Crescent relief workers and the Islamic work ethic is able to mediate this relationship. CONCLUSION: According to the findings, it can be concluded that it is possible to improve the occupational self-efficiency of relief workers through the development and reinforcement of spiritual intelligence and promotion and institutionalization of Islamic work ethic. Therefore, they will be able to play a more effective role in the achievement of organizational goals.
