The vast majority of research on social media use (SMU) is focused on its negative effects while often disregarding that it can also help adolescents form and maintain a network of social relations and support. This study explores the possibility of predicting SMU intensity based on peer attachment dimensions (Trust, Communication, Alienation) and FoMO on a sample of adolescents (N = 557; M_age = 18.09; SD_age = _.275). The results show that Trust and Communication (merged in one dimension of Peer support) are positive predictors of SMU and that this effect is partly mediated by FoMO which was also found to be a positive predictor. Alienation was not a significant predictor in the first step of regression analysis, but it became significant upon the addition of FoMO. The indirect effects analysis showed that FoMO suppresses the effect of Alienation on SMU intensity - the stronger FoMO the smaller the effect of Alienation. To sum up, when there is trust and good communication in relationships with friends, but also Fear of missing out, there will be more intensive use of SM. In addition, although being alienated from friends can restrict the use of SM, this effect is diminished if there is Fear of missing out. Taken together, these results point to the role of peer attachment and FoMO in predicting the intensity of SMU which can be viewed not as a negative phenomenon but as a way of acquiring social capital and a means of preserving and maintaining already acquired social capital.

The basic aim of this research was to evaluate the psychometric properties of the Index of Problematic Online Experiences (I-POE) on a sample of adolescents from Serbia. Construct validity, which had previously been tested by the authors of the test themselves (Mitchell, Jones, Wells, 2013), was retested here. The possibility of predicting I-POE scores based on selected personality traits and parental mediation was also evaluated. A total of 339 students from two cities in Serbia, aged 18 and 19, participated in the study. The results indicated that very similar behavior determined problematic Internet use (PIU) both in this research and that of the authors of the test. Construct validity testing indicated that the scores on the I-POE predicted online perpetration, sexual behavior and victimization, as expected. Negative valence was correlated with the I-POE scores with mediation effect of Parental involvement. The results indicate that I-POE encompasses significant characteristics of PIU as a global phenomenon and it can be of significant importance in assessing this problem among the adolescent population.

This article elaborates the characteristics of knowledge management in the context of occupational safety and presents the results of research based on the assumption that there is a link between knowledge management and occupational safety performance, and that knowledge management can help in improving occupational safety performance. The research involved 645 occupational safety experts from three Balkan countries (Slovenia, Croatia and Serbia). The results showed that the knowledge management in the organization is related to all of the observed aspects of occupational safety performance: number of work-related injuries within the organization; number of lost working days due to injuries; costs caused by work-related injuries and occupational diseases; financial investments in occupational safety; assessment of the state of occupational safety. The practical implications of the article can be seen in the context of meeting the educational needs for continuous learning and improvement of knowledge/lifelong learning in the field of occupational safety.

The Conspiracy Mentality Questionnaire (CMQ) is a generic conspiracy mentality questionnaire whose content is suitable for different linguistic and cultural contexts. However, it needs to demonstrate strong measurement properties across these contexts to be effective. This study aimed to explore the psychometric properties of the CMQ across four different languages: Serbian, Bulgarian, Greek, and English. Despite its widespread use, the CMQ lacks sufficient research on its psychometric properties, especially in terms of measurement invariance across different linguistic versions (apart from the parent study). Moreover, to the best of our knowledge, no study has investigated the equivalence of the CMQ across genders, even though it is used for gender comparisons. To address this gap, we analyzed data from 2,897 participants (76.1% female) aged 18-89. Confirmatory factor analysis supported the modified one-factor structure, with a correlated residual that was replicated/previously reported, across languages. Measurement invariance analysis confirmed metric invariance across languages and scalar invariance across genders. Scalar invariance was established across education for Serbian, Bulgarian, and, with some caution, Greek, while it was not a property of the English sample. The nomological network of the CMQ aligns with previous findings regarding the correlates of conspiracy mentality.
