The present study was conducted to determine the effectiveness of mindfulness-based well-being training on occupational stress, resilience, and academic optimism among female teachers in Zahedan. This study employed a quasi-experimental design with a pretest-posttest control group. The statistical population comprised all female elementary school teachers in Zahedan during the 2024-2025 academic year, from which 40 participants were selected using multistage random sampling and randomly assigned to experimental (n=20) and control (n=20) groups. The experimental group received mindfulness training over eight two-hour sessions. The research instruments included the Occupational Stress Inventory (Osipow, 1998), the Academic Optimism Questionnaire (Beard et al., 2010), and the Connor-Davidson Resilience Scale (2003). Data were analyzed using Multivariate Analysis of Covariance (MANCOVA). The results demonstrated that mindfulness-based well-being training had a significant effect on reducing occupational stress (F=36.37, p=0.001, η²=0.51) and increasing academic optimism (F=24.17, p=0.001, η²=0.41) and resilience (F=6.84, p=0.013, η²=0.16) among teachers. The effect sizes indicated a strong impact of the intervention on improving the studied variables. Therefore, it can be concluded that mindfulness-based well-being training can be utilized as an effective intervention to promote mental health and reduce occupational pressures among teachers.

Cognitive flexibility is critical for psychiatric nurses facing high-stress environments, yet effective interventions to enhance this skill are underexplored. This quasi-experimental study aimed to evaluate the impact of Acceptance and Commitment Therapy (ACT) on cognitive flexibility among psychiatric nurses. Sixty-two nurses from Razi and Saraye Ehsan psychiatric centers in Tehran were randomly assigned to experimental and control groups (n = 31 each). The experimental group participated in eight 90-minute group-based ACT sessions, adapted from Mohagheghi et al. (2015), incorporating interactive exercises, mindfulness practices, and homework to foster psychological flexibility. The control group received no intervention. Cognitive flexibility was assessed using the Cognitive Flexibility Inventory (CFI) at pretest and post test. Paired t-tests and analysis of covariance (ANCOVA) were employed to analyze within-group and between-group differences, controlling for pretest scores. The experimental group showed a significant increase in CFI scores (M_diff = 17.14, SD = 5.27; t(30) = 18.12, p < .001). ANCOVA revealed a significant group effect (F(1, 60) = 19.63, p < .001, η² = 0.71), with 71% of post test score variance attributed to the intervention. No significant demographic differences were found between groups. The findings suggest that ACT is an effective intervention for enhancing cognitive flexibility among psychiatric nurses, potentially improving their ability to cope with workplace stress. However, the small sample size and lack of long-term follow-up limit generalizability. Future research should explore ACT’s sustained effects and applicability across diverse healthcare settings.

Resilience is a psychological characteristic that enables individuals to return to their normal lives after experiencing adversity and stressful situations, thereby preventing feelings of failure and defeat in life. In medical communities, due to high-pressure job demands and environmental stressors, resilience is considered one of the most critical components of psychological well-being, closely linked to one’s professional role and job satisfaction. In this regard, the present study investigates the effect of the Five Major Personality Factors on resilience, with the mediating role of cognitive emotion regulation. The statistical population consisted of physicians working at Imam Reza Hospital in Tabriz during the second half of the 2024-2025 academic year. Following the acquisition of the ethics approval code (IR.IAU.TABRIZ.REC.14040.182) a sample of 384 individuals was selected based on Morgan's table through stratified random sampling with proportional allocation across four strata: internal medicine (male), internal medicine (female), neurology (male), and neurology (female), according to the actual distribution in the population. The participants completed the NEO Five-Factor Inventory (NEO-FFI; 1985), the Connor-Davidson Resilience Scale (CD-RISC; 2003), and the Cognitive Emotion Regulation Questionnaire (CERQ; Garnefski & Kraaij, 2006). Data were analyzed using structural equation modeling (SEM) with partial least squares (PLS) in Smart PLS software. The results indicated that all of the Five Major Personality Factors, except for openness to experience and agreeableness, had a significant effect on resilience. Moreover, all personality traits except agreeableness significantly influenced resilience through the mediating variable of cognitive emotion regulation. Based on these findings, it can be concluded that individuals’ level of resilience is influenced by their personality traits and the factors affecting their emotion regulation.

Objective: Obesity is a complex, multifactorial, chronic, and progressive disease that has become a crucial public health problem worldwide. Therefore, it seems necessary to identify risk and protective factors to prevent obesity and treat obesity. This study aims to identify the risk and protective factors of obesity in women. Method: The study was descriptive-correlational. The research sample consisted of 429 overweight and obese women, selected through voluntary sampling. To collect data, a physical activity questionnaire, core beliefs of eating questionnaire, self-criticism questionnaire, shame and guilt scale, self-esteem scale, body image concern questionnaire, stress-anxiety-depression questionnaire, and weight self-efficacy questionnaire were used. The obtained data were analyzed using stepwise regression using SPSS 24. Results: The findings showed that among obesity risk factors (core beliefs of eating, self-criticism, shame and guilt, concern about body image, stress-anxiety-depression), the core beliefs of eating, stress, and depression can predict obesity. Also, the research results showed that among obesity protective factors (weight self-efficacy, self-esteem, and physical activity), weight self-efficacy can predict obesity improvement more than other variables. Conclusion: Based on the results of the present research, we can say that the variables of core beliefs about eating, stress, and depression as risk factors and the variable of self-efficacy as a protective factor can predict body mass index.
