The studies since the second half of the 20th century have revealed the effect of stress on the heart and vessels with mediating neurological indicators and techniques of dysfunctional coping techniques. They also have shown that stress management and the improvement of coping techniques improve the indicators. The present study examined the appraisal of the effect of coping-therapy on cortisol, Interleukin 6 (IL-6) and Interleukin 1β (IL-1β) in comparison with the control group. The study was a quasi-experimental research with pre-test and post-test design conducted on 44 patients (randomly assigned into two experimental and control groups) suffering from coronary heart disease who were hospitalized in Shahid Rajaei Heart Hospital in Tehran in 2011. The experimental group was treated with coping-therapy, and the immunological indicators of both groups were measured using ELISA at the beginning, the fourth, the eighth, (immediately after the end of treatment), the tenth, and the fourteenth weeks. The collected data were analyzed using repeated measures ANOVA by SPSS version 17. The gender and education of the sample was controlled statistically. The results revealed that coping-therapy could significantly decrease cortisol, IL-6, IL-1β from the eighth to the end of the fourteenth week (follow-up). Considering the cognitive limitations of the present study, one can conclude that coping-therapy may decrease the negative effects of stress on immunological indicators through improving dysfunctional techniques to effective ones, and in this way, reveal the positive effects on health.

Background: This study aimed to compare quality of working life and memory self-efficacy beliefs in people with different circadian rhythms and physical activity levels. Materials and methods: The study took a causal-comparative method. Subjects consisted of 149 fixed and rotating shift employees, working in health enters and hospitals that were participated based on inclusion criteria. The subjects completed demographic, international physical activity, quality of working life and memory self-efficacy questionnaires. All data were analyzed using two-way ANOVA and Bonferroni post hoc test. Result:The results show that the quality of working life and memory self-efficacy are different in fixed and rotating shift employees at three levels of high, medium and low physical activity. Employees with fixed shift and high and medium physical activity level have higher quality of working life and memory self-efficacy than other employees. Moreover, quality of work life of fixed shift employees with medium and low physical activity is better than quality of working life of rotating shift employees with medium and low physical activity, and quality of working life of rotating shift employees with high physical activity levels were significantly better than quality of working life of rotating shift employees with medium and low levels of physical activity (PConclusion: Choosing active lifestyle is recommended to fixed and rotating hospital employees in order to avoid reduction of quality of working life and memory self-efficacy.

Background: The aim of the present study was to predict cognitive failures in the elderly based on personality dimensions and lifestyle and examine the mediating role of negative emotions as a model. Materials and Methods: This research is of correlation type and its statistical population included all the elderly in Tehran. In the present study, 150 elderly persons participated by convenience sampling method. Research instruments were cognitive failures, Eysenck Personality Inventory, lifestyle scale and Negative emotions. In order to analyze the data, the path analysis and stepwise regression analysis were used. Results: The results showed that personality dimensions and lifestyle can significantly and negatively predict emotions and cognitive failures and finally with respect to the proposed model, it was found that lifestyle and personality dimensions could significantly predict cognitive failures through the mediation negative emotions. Conclusions: The result obtained from this study can be used to identify the groups vulnerable to cognitive failures and make necessary recommendations to the experts to understand the causes and etiology, consultation and prevention of cognitive failures.

Objective: Due to unpleasant consequences of depression in patients suffering from cardiac diseases, such as increase in mortality rate during the first year, especially after undergoing a surgery; this study addresses structural relationships between cognitive and behavioral variables including illness perception and coping strategies in predicting depression after undergoing Coronary Artery Bypass Grafting (CABG) and Percutaneous Coronary Intervention (PCI). Besides, one of the cognitive models for assessing psychological adaptation with chronic medical diseases was outlined for the first time. Method: The sample comprised 245 coronary patients confronted with the diagnosis for the first time, who had undergone PCI and CABG interventions. They were chosen and interviewed through convenience sampling following one month of initiating treatment process. For this purpose, Beck Depression Inventory for Primary Care (BDI-PC), Coping Inventory for Stressful Situations (CISS-21) and the short format of Disease Perception Questionnaire were administered. Data was analyzed using structural equations modeling (LISREL software). Results: findings indicated that applying emotion-focused coping strategies determined 40% of depression variance in these patients, whereas problem-focused strategies determined 4.5% of it and avoidant coping strategy didn’t have a significant role in depression. On the other hand, illness perception as a cognitive variable, could directly determine 26% of depression and 4.5% of it through emotion-focused strategies and 0.25% by means of problem-focused strategies. Also illness perception, could meaningfully determine 50% of emotion-focused coping variance, 7% of problem-focused variance and 8% of avoidance variance. Conclusion: Overall results of this study supported Leventhal’s theoretical model of self-regulation and verified the role of cognitive variables (illness perception) and behavioral ones (coping strategy) in emerging depression. Therefore it is recommended that much attention be drawn to the process of developing patient’s illness perception through personal or group trainings and if necessary, offering effective cognitive and behavioral treatments by practitioners.
