    (Istanbul Univ, Methodology & Sociology Research Center, 2025) Aytac, Sevinc Serpil; Bilir, Kadriye Burcu Ongen; Aydin, Gulden Cetin; Yuzaki, Engin
    The widespread use of digital technologies and the increasing prevalence of internet usage in a globalized world have significantly influenced individuals' personality traits. In particular, the restriction of face-to-face interactions during global pandemics has led individuals to maintain their lives in digital environments. These developments have made it increasingly important to investigate the relationship between internet use and personality characteristics. This study aims to adapt the Online Narcissistic Personality Inventory (ONPI), developed by Chou and Farn (2015) based on the 40-item Narcissistic Personality Inventory by Raskin and Terry (1988), into Turkish and to examine its psychometric properties. The study sample consists of 397 individuals from diverse age groups and socio-demographic backgrounds. Data was analyzed using SPSS 30 and AMOS 30 software. According to the results of the exploratory factor analysis, the item factor loadings ranged from 0.466 to 0.812, and the total variance explained by the scale was found to be 58.36%. Confirmatory factor analysis results (Chi-square/df:2.584; RMSEA:0.063; NFI: 0.84; IFI: 0.90; TLI: 0.87; CFI: 0.90; GFI: 0.90) indicated that the scale exhibits a five-factor structure with 27 items. The internal consistency of the scale was high, with a Cronbach's alpha coefficient of 0.93. Additionally, the item total correlations ranged between 0.326 and 0.700. The findings demonstrate that the Turkish adaptation of the Online Narcissistic Personality Inventory is a valid and reliable measurement tool.

    (Istanbul Univ, Methodology & Sociology Research Center, 2024) Aytac, Serpil; Bayram-Arli, Nuran; Dev, Mine Aydemir
    The aim of the study is to test the mediating role of happiness in the relationship between stress and quality of life. The study uses the Turkish version of the World Health Organization's (WHO) brief Quality of Life (WHOQOL-BREF) Scale to measure quality of life. The WHOQOL-BREF Scale has four main domains: physical, psychological, social relations, and environmental. In addition, the study uses the Turkish version of the Oxford Happiness Questionnaire to measure individuals' happiness levels and the stress sub -scale from the Turkish adaptation of the Depression, Anxiety, and Stress Scale (DASS-42) to measure stress levels. A total of 216 people aged 18 or older participated in the study. Model 4 in Process Macro was used to test the hypotheses related to the research model. The highest relationship between domain values was obtained between the psychological and physical domains. According to the mediation analysis findings, happiness mediates the relationship between stress and all domains of quality of life. These results emphasize the importance of happiness in individuals' lives. The study has concluded stress to have an indirect and large effect size on all domains of quality of life and found the highest indirect effect size of stress to be on the psychological domain. Based on the results, paying special attention to happiness levels is suggested in order to improve quality of life, the ability to cope effectively with stress and tension, and to empower oneself.

    Measurement of Perceived Psychological Safety: Integration, Review and Evidences for the Scale in the Context of Turkiye
    (Istanbul Univ, Methodology & Sociology Research Center, 2022) Bulbul, Secil; Isiacik, Serin; Aytac, Serpil
    Psychological safety can predict many positive individual and organizational outcomes at work, and previous research addressed how psychological safety contributes to positive work attitudes and behaviors. In Turkey, there is quite an amount of research showing the contributing role of psychological safety perception on employees' positive performance behaviors and organizational effectiveness and innovativeness. However, previous research in Turkey does not adequately show the reliability and validity of the psychological safety scale, which was developed by Edmondson (1999). Based on the suggested requirement this study aimed to investigate the psychological safety perceptions of individuals who work in various sectors in Turkey. The adapted version of the psychological safety scale was used to gain evidence for the reliability and validity of the instrument in Turkey. In total, 585 individuals working in various industries and from various occupational groups participated in the research. Both exploratory factor analysis and the confirmatory factor analysis showed that Turkish adapted version of the psychological safety scale was valid and reliable.
