Objective: Multiple Sclerosis (MS) is one of the most common chronic diseases of the central nervous system, and the disability resulting from the disease impacts self-efficacy and various mental health dimensions of these patients. Therefore, the present study aimed to propose a structural model for predicting psychological well-being and emotional regulation based on resilience and self-efficacy among MS patients in Tehran. Methods: Given its objective, this research is of the applied type and descriptive in nature concerning data collection methods, specifically employing structural equation modeling. The statistical population of this study included all individuals with MS attending treatment centers in Tehran in 2021, with a minimum sample size estimated at 150. The variables studied were based on the Ryff's Psychological Well-being Scale, the Gross and John's Emotional Regulation Questionnaire, the Connor-Davidson Resilience Scale, and the Schwarzer and Jerusalem's Self-Efficacy Scale. Ultimately, data were analyzed using structural equation modeling in AMOS software. Findings: According to the study's findings, all standardized coefficient values related to the dimensions of the latent variables were higher than 0.4, indicating that this measurement model has adequate reliability regarding the items of latent variables. Critical ratio values are usually introduced as validity parameters associated with the structural model and, in this study, all values were significant and outside the range of (-1.96, 1.96), with Cronbach's alpha and composite reliability values greater than 0.7 and AVE values greater than 0.5. Conclusion: Thus, the model enjoys appropriate validity and reliability.

Objective: This study aimed to predict self-harming behaviors based on cognitive emotion regulation strategies and emotional distress tolerance, with the mediating role of internalized shame in adolescents visiting harm reduction centers in Tehran. Methods: The research employed a descriptive correlational design. The statistical population included adolescents aged 14 to 18 who attended drop-in harm reduction centers in District 12 of Tehran (Shush-Harandi neighborhood) during the first four months of 2022. A total of 300 participants were selected using purposive sampling. The research tools included the Self-Injury Questionnaire (Sansone et al., 1998), the Cognitive Emotion Regulation Questionnaire (Garnefski et al., 2001), the Distress Tolerance Scale (Simons & Gaher, 2005), and the Internalized Shame Scale (Cook, 1993). Data were analyzed using structural equation modeling and AMOS24 software. Findings: The results indicated a relationship between cognitive emotion regulation strategies (-0.39), emotional distress tolerance (-0.41), internalized shame (0.36), and self-harming behaviors (P < 0.01). Furthermore, internalized shame mediated the relationship between cognitive emotion regulation strategies (B = 0.52) and emotional distress tolerance (B = 0.45) with self-harming behaviors in adolescents (P < 0.01). Conclusion: Based on these findings, it can be concluded that since internalized shame mediates the relationship between cognitive emotion regulation strategies and emotional distress tolerance with self-harming behaviors, focusing on factors influencing these behaviors can help reduce the risks associated with this developmental period.
