 Objective: Irritable bowel syndrome is a chronic psychosomatic disease. Stressful events play a critical role in this disease, and lifestyle modification is one of the treatment priorities for these patients. The present study aimed to examine the role of health-enhancing lifestyles among stressful life events and salutogenic health indicators in these patients. Method: Data analysis was done by structural equation modeling. The statistical population included all patients with irritable bowel syndrome referred to Imam Sajjad Hospital in Tehran in 2019 and 2020. The statistical sample was 229 patients selected through Purposive sampling and diagnosed by a psychiatrist based on ROME-IV criteria. Research tools included the Bringsen Salutogenic Health Indicators Scale, Sarason Life Events Inventory, and Walker HealthPromoting Lifestyle Profile-II. Data analysis was done by SPSS-20 and LISREL-8 software. Ethical considerations based on confidentiality, respect for the rights of individuals, human dignity, and avoiding harming the participants and distorting information were observed. Also Participants had full authority to withdraw from the study at any time. Results: The relationship between lifestyle (t=2.723, ß=0.17) and stressful events (t=-2.31, ß=-0.42) with salutogenic health indicators was significant. The mediating role of lifestyle between life events and salutogenic health indicators was meaningful at P<005 and a standard coefficient (0.0-13.11). Conclusion: It seems that lifestyle and control over stressful events affect the health indicators of patients with irritable bowel syndrome. Therefore, it is suggested to provide appropriate training programs to control and manage stressful events and provide strategies to modify lifestyle to improve health. 

Objective: Somatic symptoms consist of a wide range of symptoms and until yet clustering them has been very challenging for researchers and therapists. The present study aims to explore underlying psychological factors of various functional somatic symptoms and determine if there are any similarities or differences in these factors that could help classify these symptoms as one syndrome or discrete ones. Method: This study adopted an association rule mining method based on data mining. 643 participants were recruited using a convenience sampling technique. Data were collected using the checklist of somatic symptoms (Lacourt et al., 2013), Attachment Questionnaire (Hazan & Shaver, 2017), Defense Style Questionnaire (Andrews et al., 1993), and Levels of Emotional Awareness Scale (Lane, 2006). Results: Cognitive, gastrointestinal, and fatigue symptoms are related more to immature defense mechanisms. Musculoskeletal, respiratory, and cardiac symptoms are associated with neurotic defenses. Fatigue symptoms are associated with ambivalent attachment and musculoskeletal symptoms are related more to avoidant attachment. Indeed, it could be said that there are two clusters of somatic symptoms, one of which is attachment and the other is defense mechanisms. This supports the splitters’ view about somatic syndromes. Conclusions: These findings show various types of somatic symptoms have qualitatively different risk factors. Our findings imply that psychotherapists should consider the kind of syndromes a patient has and their underlying psychological predispositions to manage the problem better.  

The aim of this study is to investigate the role of personality traits in prediction of perceived rejection, age feeling, and social exclusion among retirees in Zahedan city. The statistical population of this study includes all retirees in Zahedan city in 2021 – 2022, of which 123 people were selected as samples through the convenience sampling method. To collect data for this study, questionnaires on personality traits, cognitive health, perception of rejection, feeling of aging, and social isolation were used. Pearson correlation coefficient, stepwise multiple regression, and simple linear regression were used to analyze the research data. The results showed that the perception of rejection had a positive and significant correlation with neuroticism (p<.05) and a negative and significant correlation with extraversion, agreeableness, and conscientiousness (p<.01). However, there was no significant correlation between perceived exclusion and openness to experience. According to the results of the study, it can be concluded that personality traits play a significant role in predicting perceived exclusion, feeling of aging, and social isolation in retirees.

The purpose of the research is to analyze the effects of ethical leadership and organizational politics on individual and team creativity, focusing on the mediating role of knowledge hiding. The study is a descriptive-correlational survey and is applied in terms of purpose. The statistical population included employees of selected public organizations in the Eqlid County, totaling 950 individuals. 270 individuals were selected using a non-probability convenience sampling method based on the rule of thumb for SEM as the sample. To collect data, the following measures were used: Brown's et al. (2005) Ethical Leadership scale, the Organizational Politics scale by Kacmar and Carlson (1997), the Knowledge Hiding scale by Serenko and Bontis (2016), the Individual Creativity scale by Zhou and George (2001), and the Hanke's (2006) Team Creativity scale. The validity of scales was confirmed using the content validity, and the reliability was examined using Cronbach's alpha, yielding values of 0.89 for the Ethical Leadership, 0.82 for the Organizational Politics, 0.92 for the Knowledge Hiding, 0.87 for the Individual Creativity, and 0.85 for the Team Creativity. For data analysis, SEM and the AMOS software were used. The results of the study fitted the research model, indicating that ethical leadership and organizational politics have a significant negative impact on knowledge hiding. Additionally, knowledge hiding has a significant negative effect on both individual and team creativity of employees. By reducing knowledge hiding behaviors through ethical leadership and organizational politics, the level of creativity among employees at both individual and team levels increases.
