Adverse childhood experiences, symptoms of anxiety and depression in adulthood: Mediation role of life history strategy.

Life history theory has considered the effects of childhood experiences. The present study aimed to investigate the mediating role of life history strategy and the moderating role of gender in the relationship between childhood experiences and symptoms of anxiety and depression in adulthood. In this study, 248 Iranians (including 162 females and 86 males) between 18 and 53 voluntarily participated and responded to all online questionnaires regarding the COVID-19 pandemic. The data were analyzed with SPSS and macro PROCESS. The mediation analysis results demonstrated that the life history strategy mediates the relationship between childhood experiences and symptoms of anxiety and depression. The moderated mediation analysis revealed that there were no gender differences in the moderated mediation. The results have highlighted the importance of life history strategies in the association between childhood experiences and depression and anxiety symptoms and can be considered in the design of interventions based on the prevention of people's vulnerability to mental disorders.

The relationship between perfectionism and interpersonal sensitivity with self-compassion in university students: the mediation of repetitive negative thinking.

Self-compassion is a construct of positive psychology related to personality and cognitive factors. Perfectionism and interpersonal sensitivity are prevalent personality traits among university students and are associated with low self-compassion. Further research is required to comprehend how these mechanisms work in creating self-compassion. Consequently, the current study investigated the direct and indirect relationship between perfectionism and interpersonal sensitivity with self-compassion via repetitive negative thinking. To this end, a sample of 450 students studying in Tehran during the 2022 academic year was selected as the study sample. The results indicated that perfectionism and interpersonal sensitivity demonstrate a negative direct relationship with self-compassion, while perfectionism and interpersonal sensitivity exhibit an indirect relationship with self-compassion via repetitive negative thinking. Based on the findings, it can be concluded that the relationship between perfectionism and interpersonal sensitivity with self-compassion is not straightforward and that repetitive negative thinking can mediate this relationship. The results can be used to improve methods for increasing self-compassion and paying attention to personality, and cognitive factors can be an important step toward more effective self-compassion interventions.

Psychometric properties of the Big Three Perfectionism Scale-Short Form (BTPS-SF) among Iranian University students.

INTRODUCTION: Perfectionism is a common personality trait, particularly among university students. As awareness of this trait increases, research seeks to update tools for measuring it. The psychometric properties of the three-dimensional perfectionism scale-short form (BTPS-SF) have not been studied in the Iranian population. Therefore, this study aims to investigate the psychometric properties of this 16-item scale among Iranian university students. METHODS: The statistical population for this research included all students in Tehran. From this population, 528 students were selected, and data analysis was performed using SPSS 26 and AMOS 24 software. RESULTS: The findings showed that the BTPS-SF has acceptable validity and reliability. Furthermore, a positive and significant correlation was found between perfectionism and interpersonal sensitivity, whereas a negative and significant correlation was found between perfectionism and self-compassion. CONCLUSION: Given the desirable psychometric properties of the Persian version of the BTPS-SF, its use can be recommended to psychology experts in research and clinical evaluation situations.

Sensitivity to punishment and emotional eating: The mediating role of shame and rumination.

OBJECTIVES: The relationship between sensitivity to punishment (SP) and emotional eating has been previously examined. However, effective variables in this relationship have yet to be recognized. This study aimed to investigate the relationship between SP and emotional eating via facets of shame and rumination. DESIGN: Serial Mediation model was proposed. METHOD: Female university students in Iran (n = 174) completed Sensitivity to Punishment and Sensitivity to Reward Questionnaire-Revised and Clarified (SPSRQ-RC), Dutch Eating Behaviour Questionnaire (DEBQ), Experience of Shame Scale (ESS) and Ruminative Responses Scale (RRS). RESULTS: SP showed a significant effect on emotional eating. Moreover, we observed that the relationship between SP and emotional eating was separately mediated by shame (general, characterological and bodily shame) and rumination. We further noticed the sequentially mediating role of shame (general, characterological and behavioural shame) and rumination in the relationship between SP and emotional eating. CONCLUSION: Findings suggest that high SP can increase the risk of emotional eating through negative emotions (e.g. shame) and disturbed cognitions (e.g. rumination). Therefore, for a better understanding, it seems necessary to consider emotional eating a maladaptive behaviour adopted as a possible result of the impairment of temperamental, emotional and cognitive systems.

Evaluation of psychometric characteristics of light triad personality questionnaire in nurses.

INTRODUCTION: Personality is one of the important etiological factors of psychological factors. In this regard, one of the important factors in the success of people's social and psychological life is the light triad personality. They are a combination of sympathy, compassion, and humanity. On the basis of results of the research, it is not possible to trust the psychometrics characteristics of tools; it is necessary to evaluate the psychometric characteristics of these tools. Meanwhile, the aim of the present study is the evaluation of psychometrics characteristics of light triad personality in nurses. METHODS: The statistical population includes all nurses who were employed in the summer and autumn of 2020 in private centers and hospitals affiliated with Mashhad University of Medical Sciences. The sample of this study was 245 nurses who were selected by convenience sampling. To analyze the data, exploratory and confirmatory factor analysis, Pearson correlation, total question-score correlation, and reliability analysis were used by using SPSSV22 and LISRELV8.80 software. RESULTS: The results of exploratory and confirmatory factor analysis confirmed the three-factor structure of the light triad personality questionnaire. The findings of the convergent validity of the light triad personality questionnaire were evaluated and confirmed via its simultaneous implementation by the Social Health and Emotional Sympathy Questionnaires and its divergent reliability was confirmed by the Machiavellian Questionnaire. The reliability coefficient of the questionnaire was obtained for the factors of sympathy, compassion, philanthropy, and totality by using Cronbach's alpha coefficient, 0.83, 0.75, 0.70, and 0.92, respectively. CONCLUSION: Finally, with regard to the desired validity and reliability coefficients, ease of implementation, scoring, interpretation, and explanation, as well as a short time to answer, it can be said that light triad personality questionnaires were qualified for use in psychological research to measure the rate of light triad personality.
