Öğe Examining the Relationship Between Social Support and Social Media Addiction: Role of Self-Esteem(Turkish Green Crescent Soc, 2023) Hatun, Osman; Kurtca, Tugba TurkThis study aimed to investigate the associations between social support, self-esteem, and social media addiction. The participants were 383 (55.09% female) adults aged 18-32 years (M = 21.10, standard deviation = 4.14). Data were collected using the self-report questionnaire. Correlation analysis was conducted to examine the associations between the variables. The Process Macro was employed to investigate the role of selfesteem to explain the relationship between social support and social media addiction. Bootstrap analysis was performed to investigate the significance of the direct and indirect relations between the variables. The findings demonstrated that social media addiction was negatively correlated to both social support and self-esteem, whereas social support was positively correlated to self-esteem. Gender had no significant effect on any of the variables. Even when age and daily hours of social media use were checked as covariates, according to the findings, self-esteem significantly explains how social support and social media addiction are related. Therefore, increased social support and self-esteem may prevent social media addiction.Öğe Narcissism in Social Media, Fear of Missing Out, and Social Media Addiction among College Students: A Three-wave Longitudinal Study(Springer, 2025) Hatun, Osman; Kurtca, Tugba TurkThis study explored the longitudinal relationships among narcissism in social media (NiSM), fear of missing out (FoMO), and social media addiction (SMA) among college students and the mediating role of FoMO in these associations using a three-wave longitudinal design. Data were collected using a three-wave design from 276 college students at Time 1 (T1) in October 2023, 271 students at Time 2 (T2) in April 2024, and 265 students at Time 3 (T3) in October 2024. The analyses were conducted using data from the 258 college students (57% female, M age = 21.17, SD = 1.84, range = 18-25) who participated in the study in all three time waves (both T1, T2, and T3). We conducted a three-wave cross-lagged panel modeling (CLPM) to investigate whether FoMO mediates the relationship between NiSM and SMA. This study found that both FoMO and NiSM can be significant predictors of SMA. Furthermore, the findings revealed that FoMO serves as a longitudinal mediator in the relationship between NiSM and SMA. These results highlight the importance of considering FoMO and NiSM when developing prevention and intervention programs to effectively address SMA among college students. The present study provided novel findings that enrich the empirical knowledge on social media addiction and hold significant theoretical and practical relevance.Öğe Perceived Stress, Hope, and Life Satisfaction Among College Students: A Two-Wave, Half-Longitudinal Study from Turkey(Springer, 2024) Hatun, Osman; Kurtca, Tugba TurkResearchers have long been interested in the research of perceived stress, hope, and life satisfaction. While cross-sectional studies have investigated the associations between these variables, the lack of their simultaneous consideration, particularly the mediating role of hope, in longitudinal research has left a gap in the existing literature. However, understanding these patterns throughout over time can be critical for developing successful practices and interventions to enhance well-being. Therefore, the primary objective of this study was to investigate the longitudinal relationships between perceived stress, hope, and satisfaction with life. We conducted a two-wave cross-lagged panel study to examine whether hope acts as a mediator in the association between perceived stress and satisfaction with life. Data were collected using a two-wave design from 293 college students at Time 1 (T1) in March 2023 and 250 students at Time 2 (T2) in June 2023. The analyses were conducted using data from the 250 students (mean age = 21.66, SD = 3.37) who participated in both T1 and T2. The findings revealed that hope mediated the relationship between perceived stress and life satisfaction, indicating that higher levels of perceived stress predicted significantly lower levels of hope, which, in turn, resulted in notably lower life satisfaction. These results highlight the critical role of hope as a protective factor against the detrimental effects of stress on life satisfaction. Understanding these pathways has practical implications for developing interventions to improve life satisfaction and mental health among college students.Öğe Psychopathy, impulsivity, and internet trolling: role of aggressive humour(Taylor & Francis Ltd, 2023) Kurtca, Tugba Turk; Demirci, IbrahimThe aim of this study is first to conduct the reliability and validity analyses of the Turkish adaptation of the online trolling scale. The second aim is to examine online trolling behaviour in the context of psychopathy, which is one of the personality traits of the dark triad. In the first phase, the iTroll Questionnaire was adapted to Turkish. Two hundred thirty-four university students participated in the first part of the study. At this phase, confirmatory factor analyses were conducted. Item Response Theory (IRT) analysis showed that all items of the scale were coherent and fit with the model. The results show that the scale is a reliable and valid measure. The second phase aims to investigate the mediating effect of aggressive humour on the relationship between impulsivity and iTrolling. Two hundred sixty-one adults participated in the second phase of the study. Structural equation modelling was used to examine the mediator role. The results demonstrate that aggressive humour mediates the relationship among psychopathy, impulsivity, and iTrolling. As a result, it appears critical to make trolls aware of the consequences of their actions, as impulsivity and aggressive humour contribute to trolling behaviour.Öğe Relations Among Self-Esteem, Perceived Stress, Positive Affect and College Belongingness: A Two-Wave Longitudinal Mediation Study(Sage Publications Inc, 2025) Hatun, Osman; Kurtca, Tugba TurkThe phenomenon of school belongingness and the psychological constructs that predict this phenomenon have long attracted the attention of researchers. Although cross-sectional studies have investigated the links between these variables, their lack of simultaneous treatment in longitudinal studies has left a gap in the existing literature. Therefore, the present study aimed to investigate the longitudinal relationships between self-esteem, positive affect, perceived stress, and college belongingness. To achieve this, we conducted a two-wave cross-lagged panel study to examine whether positive affect and perceived stress act as mediators in the association between self-esteem and college belongingness. The study participants consisted of 255 college students (Mean age = 20.23, SD = 2.49). The findings of this study indicated that positive affect and perceived stress play significant mediating roles in the longitudinal association between self-esteem and college belongingness. To put it simply, self-esteem indirectly predicts college belongingness through the intermediary factors of positive affect and perceived stress. This longitudinal study highlights the potential impact of self-esteem on students' levels of positive affect and perceived stress, underscoring the substantial mediator roles of positive affect and perceived stress as predictors of college belongingness.
