The aim of the present study was to investigate the mediating role of personal values ​​in the relationship between neuroticism and problematic internet use (PIU) in the student population. The statistical population of this study included all university students of Tehran city. 358 undergraduate students of Tehran, Kharazmi and Shahid Beheshti universities were selected by convenience sampling method. Participants responded to the Internet Abusive Use questionnaire, the Valued Living Questionnaire, and the Neuroticism-NEO-Five Factor Inventory. Data were analyzed by structural equation modeling as implemented in SPSS-20 and LISREL-8.53 software. The results of structural equation modeling showed that the conceptual model of the research fitted well with the experimental data and the personal values played a full mediating role in the relationship between neuroticism and PIU. The results of path analysis also showed that neuroticism has the most indirect effect on PIU through family relations value, intimate relation value, spirituality-religion value, physical well-being value, social relations value and learning. It can be concluded from the results of the study that personal values ​​play as a full mediating role in the relationship between neuroticism and PIU and in the presence of personal values, ​​direct path neuroticism and PIU was no longer meaningful.

The human mental organization has a behavioral regulative principle that operates based on certain conscious and unconscious needs. Experience of stress disrupts human mental structure and results in symptoms of psychological and physical disorders. One source of stress is having ailing children. Accordingly, this study investigates self-regulation mediational processes in the context of perceived stress in mothers of children diagnosed with cancer. The convenience sample of this study consisted of 245 mothers, who volunteered to participate and were administered the following questionnaires: Integrative self-knowledge; Self-control Scale; Self-compassion Scale; perceived stress and Chronic Self-destructiveness Scale, body-symptoms checklist. Analysis of the survey data was carried out using structural equation modeling (SEM). The analysis suggests that perceived stress is mediated through self-regulation for self-destructiveness, physical symptoms, and unpleasant self-relevant through. Therefore, exposure to stress has destructive effects both in terms of physical symptoms and on an emotional and behavioral level. The authors concluded that self-regulation was a supportive variable, helping individuals cope better with unpleasant events, retrieve their ideal mental balance and maintain their mental organization. It is implied that based on a self-regulation model, effective management of one’s mental organization can improve an individual’s capacity to effectively cope with inevitable sources of stress.

This study has aimed to investigate the mediating role of the object relations and defense mechanisms in relation between family function and  percived mental health. relations. General health questioner, family assessment device, Bell's object relation inventory and defense style questionnaire were administrated on a sample of 300 students (195 girls and 105 boys). Participants were selected, using multi-stage cluster sampling, from Khayyam University. Data were studied through path analysis method. Results indicated that object relations and mature defense mechanisms of ego played a mediating role in relation between family function and mental health. However, the immature and neurotic mechanisms of ego did not have a mediating role. Being compatible with object relation theory, this research revealed that family functions enhance mental health through affecting object relation and defense mechanisms.

The purpose of this study was to investigate the mediating role of experiential avoidance in relationship of early maladaptive schemas with illness anxiety.  The research was carried out using correlation method on 308 students of Qazvin University who were selected with convenience sampling method. Data were collected using Early maladaptive Scheme (Young), hypochondrias (Evans) and Acceptance and Action Questionnaires (Hayes). Results showed a significant role of schemas of impaired autonomy - performance and impaired limits domains in illness anxiety. Also, the role of vulnerability to harm or illness and entitlement/undeveloped schemas was significant predictor of illness anxiety. The results of hierarchical regression showed that the mediating role of experiential avoidance in the relationship between vulnerability to harm or illness and entitlement/ undeveloped schemas with illness anxiety severity was significant. It could be concluded the experiential avoidance and early maladaptive schemas were contributed in the maintenance of illness anxiety.

Psychological research in Iran had a unidimensional development and the research programs was influenced by naïve realism and blind positivism. More Recent epistemological tradition like social constructionism and discursive methodologies were ignored in psychological theories and research. The aims of this study were (1) Describing methodological issues in discursive research methods; (2) applying discursive research methods in health psychology. Discourse as a concept is derived from an ontological criticism toward the definition of science based on the objective reality and empiricism. Relying only on the objectivism and empiricism for studying human phenomena is inconsistent with some of the human mind features like intentionality and desire for cognitive consistency. Discursive approaches in health psychology is appropriate for investigating phenomena like noncompliance, representation of illness in patients’ mind and factors affecting in holding responsibility in health-related behaviors. Furthermore, discursive methods could reveal how social discourse and social power could determine the definition of health and responsivity for health related issues. Some of the main analytic methods in discursive methodologies are conversation analysis, identification the discursive performance, finding discursive strategies, and discovering interpretative repertoires. Discursive methodologies could investigate health from the ways of applying language in social context and produce knowledge related to ways people position themselves toward health discourses. So, applying discursive methodologies in health psychology could help health psychologists to find better ways to promote health care and produce novel insights about how clients construct health and illness.

This study was designed in order to evaluate the reliability and validity of Persian version of Self- concept clarity (SCC).The present study is a descriptive- correlation study. 577 students  who were selected via available sampling method. After forward and backward translations of the Self- concept clarity, the original version was compared with the Persian version .Similarities and differences were reviewed and corrected. After the scale was prepared, the Cronbach's alpha test was used to determine the validity of the test. To determine the validity of construct validity methods, convergent and divergent validity was used. Data were analyzed using Factor analysis and Pearson’s correlation method. The findings of factor analysis indicated that this scale is uni-factor in the Iranian sample. Confirmatory factor analysis confirmed the factor structure resulted from exploratory factor analysis which was not different from the proposed factors in original questionnaire. Test-retest reliability was 0.85 and internal consistency of the scale was 0.83 by using Cronbach's alpha, Correlation between the two half-tests was 0.67. Also, the correlation with Rogers self- concept scale was -0.62 and correlation with physiological symptoms sub-scale was -0.13.The results show that the persian version of the of self-concept clarity is a reliable and valid scale.
