Objective: The present study aimed to develop a predictive model of treatment adherence based on psychological flexibility with the mediating role of positive and negative meta-emotions in patients with multiple sclerosis (MS) attending MS centers in Isfahan. Methods and Materials: The research employed a correlational design using structural equation modeling (SEM) and was applied in terms of its objective. The statistical population included MS patients who visited MS centers in Isfahan. Based on the research objectives, variables, and using convenience sampling, a sample of 285 participants was selected. The study utilized the Medication Adherence Questionnaire by Madanlou (2013), the Psychological Flexibility Questionnaire by Dennis and Vander Wal (2010), the Self-Compassion Scale by Reiss et al. (2011), and the Positive and Negative Meta-Emotions Questionnaire by Mitmansgruber et al. (2009) for data collection. To assess the research model, the two-step method proposed by Anderson and Gerbing (1988) was used, and the model was constructed accordingly. It is worth noting that all analyses were conducted using version 24 of the AMOS structural equation modeling software. Descriptive statistics (mean, standard deviation, frequency) and inferential statistics (correlation matrix, regression, and fit indices) were applied. Findings: The findings indicated that psychological flexibility and positive meta-emotions positively predicted treatment adherence, while negative meta-emotions negatively predicted it. Furthermore, according to the bootstrap test results, psychological flexibility exerted an indirect positive effect on treatment adherence through the mediating role of positive and negative meta-emotions with a coefficient of 0.22, which was statistically significant at the 0.01 level. This effect highlights the mediating role of both positive and negative meta-emotions. Conclusion: The findings indicate that psychological flexibility, through positive and negative meta-emotions, plays a significant role in enhancing treatment adherence in MS patients and can serve as a foundation for targeted psychological interventions.
