Objective: Family dynamics play a significant role in establishing emotional relationships among its members and fostering psychological well-being, which extends to individual and collective members' peace of mind. This study aimed to investigate the impact of parenting styles and sexual education styles of parents, with anxiety as a mediating variable, on the sexual performance of married women. Method: The study population consisted of married women who presented with sexual dysfunction at psychiatric and women's clinics in Tehran. Since the minimum number of samples in structural equation modeling is 200 individuals, 200 individuals were selected through convenience sampling. The research instruments included Baumrind's Parenting Styles Scale (1972), Parental Sexual Education Styles Scale (2010), Beck Anxiety Scale (1990), and Rosen et al.'s Sexual Performance Scale (2000). Structural equation modeling was employed to analyze the data. Results: The findings of the present study showed that anxiety does not have a mediating effect on the effect of parents' strict sexual education style on the sexual performance of married women, but it has a complete mediating effect on the sexual performance of married women in the authoritative sexual education style of parents. Also, anxiety has a partial mediating effect on the impact of parents' authoritarian parenting style on married women's sexual performance, and it does not have a mediating effect on the parents' authoritarian parenting style on married women's sexual performance (p > 0.05). Conclusion: The study concludes that the sexual performance of married women is significantly influenced by the styles of parenting and sexual education they received, with anxiety playing varied mediating roles. An authoritative approach to sexual education, coupled with parenting styles that manage to reduce anxiety, tends to enhance sexual performance in women.

Objective : The present study aimed to present and investigate the structural model of the effectiveness of the cognitive-based intervention on cortisol and lipid profiles, with the mediating effect of cognitive flexibility and behavioral brain systems in overweight people with high stress. Method : The research design was experimental with a control group, pre-test-post-test, and follow-up design. Multivariate analysis of covariance was used to analyze the data. The statistical population of this research was all 190 people referred to the cosmetic surgery clinic in 2023. The research sample consisted of 30 people (15 for the experimental group and 15 for the control group) selected through the purposeful sampling method and according to the research inclusion and exclusion criteria. The respondents answered the Behavioral Activation / Inhibition Systems Scale (Carver & White, 1994) and Connor and Davidson’s Flexibility Questionnaire (2003). A semi-structured interview was used to measure stress. Results : The results of univariate covariance analysis showed a significant difference between the two experimental and control groups in the variables of brain-behavioral systems (F = 3.824, P = 0.035) and cognitive flexibility (F = 4.958, P = 0.032). Also, the effectiveness of the cognitive intervention on cortisol was 0.70. It means that 79% of the changes obtained in the post-test scores of the experimental group were due to the intervention. Conclusion : We can conclude that stress leads to an increase in overweight and a reduction in an individual's flexibility and positive attitude toward body image. Therefore, using Yoga, breathing exercises, cognitive therapy, and treating overweight people to manage their stress correctly is necessary.
