Online gaming has become an essential form of entertainment with the advent of technology and a large sway of research has been undertaken to understand its various permutations. Previous reviews have identified associations between the Big Five personality traits and online gaming, but a systematic review and meta-analysis on the association between these constructs has yet to be undertaken. In the current study we aimed to fill this gap in the literature through a systematic review and meta-analysis comprising of 17 studies and 25,634 individuals (Age_Mean = 26.55, males = 75%). The findings showed that agreeableness, extraversion, openness to experience, and neuroticism were not ubiquitously associated with online gaming. The findings showed that only conscientiousness, across samples, had a protective role in online gaming. Furthermore, there were non-significant variations in the Big Five personality traits associations with online gaming when comparing gamers to the general population, younger versus older participants, casual versus ‘hardcore’ gamers, and high versus low traits (with the exception of neuroticism). As a result of our observations, the underlying mechanisms of individual differences in online gaming remain unclear. Limitations and future directions for research are discussed.

The present study explored the relationships between perfectionism and academic procrastination. 200 students (92 males, 108 females) were selected from universities in the city of Tehran through multistage cluster-random sampling. All subjects were asked to complete the following questionnaires: Multidimensional Perfectionism Scale (MPS-F; Frost et al., 1990) and Procrastination Assessment Scale-Students (PASS; Solomon & Rothblum,1984). Three dimensions and total scores of perfectionism (concern over mistakes, parental criticism, and doubts about actions) were found to be positively and significantly correlated with academic procrastination and organization dimension negatively and significantly correlated with it. In other words, individuals with higher scores in perfectionism scale revealed more academic procrastination in comparison with individuals with lower scores. The findings provide preliminary support for the role of perfectionism in the maintenance of academic procrastination

This study was designed to investigate the effectiveness of life skills training on happiness, quality of life and emotion regulation in Tarbiat Moallem students. This study is a quasi-experimental with pre-test post test and control group design.26 students of Tarbiat Moallem University were randomly selected and assigned to two experimental and control group. The experimental group attended in sessions of life skills training (coping with negative mood, effective relationship, assertiveness, anger management and stress management) which altogether lasted for three hours. Oxford Happiness Questionnaire, World Health Organization Quality of Life Questionnaire and Shute Emotion Regulation Questionnaire were administered for both groups. Data were analyzed using ANCOVA and MANCOVA method. Life skills training showed to have made a significant difference in the scales of happiness and emotion regulation and quality of life in psychological health, social relationship and physical situation subscales. But there were no significant difference in the physical health subscale. Life skills’ training is an effective intervention for increasing happiness, quality of life and emotion regulation

Objective: This study aimed to explore the structural relation of emotional schemas with psychological distress and evaluate the mediating role of resilience and cognitive flexibility in this relationship. Method: Participants were 300 students that voluntarily completed a questionnaire package that included the Leahy Emotional Schema Scale (LESS-P), Connor-Davidson Resilience Scale (CD-RISC), Cognitive Flexibility Inventory (CFI), and Depression Anxiety Stress Scale (DASS-21). Then, we utilized the LISREL software for structural equation modeling. Results: Structural equation modeling and path analysis revealed the direct effects of adaptive and maladaptive emotional schemas on psychological distress. The results indicated that maladaptive emotional schemas indirectly affected psychological distress via resilience and cognitive flexibility (P < 0.01). In contrast, adaptive emotional schemas indirectly affected psychological distress via cognitive flexibility rather than resilience (P < 0.05). Evaluation of the proposed structural model revealed an acceptable fit. Conclusion: The present research findings show the effect of emotional schemas on psychological distress via resilience and cognitive flexibility. Furthermore, the results suggest that resilience partially mediates the relationship between emotional schemas and psychological distress. At the same time, cognitive flexibility mediated this relationship.
