Abstract

This study aimed to examine the relationship between self-confidence and public speaking anxiety among students of the Faculty of Law at Universitas Medan Area. The study employed a quantitative approach with a correlational research design. The research population consisted of 354 active students, with a sample of 102 students selected using a purposive sampling technique. The research instruments consisted of a 24-item self-confidence scale and a 20-item public speaking anxiety scale, both using a five-point Likert scale model. The instruments underwent adaptation procedures, content validity assessment, and reliability testing, resulting in Cronbach’s Alpha coefficients of 0.87 for the self-confidence scale and 0.89 for the public speaking anxiety scale. Data analysis was conducted using IBM SPSS through descriptive statistics, normality testing, linearity testing, and Pearson Product Moment correlation analysis. The findings revealed a significant negative relationship between self-confidence and public speaking anxiety, with a correlation coefficient of r = -0.71 and p = 0.000 (p < 0.05). The coefficient of determination of 0.51 indicated that self-confidence contributed 51% to the variance in public speaking anxiety. These findings suggest that students with higher levels of self-confidence tend to experience lower levels of public speaking anxiety. However, because this study employed a correlational design, the findings cannot be interpreted as evidence of a causal relationship.

Abstract

The rapid development of digital technology and e-commerce has increased the ease of online shopping activities, but it has also contributed to the rise of consumptive behavior, particularly among university students with high levels of technology use. This study aimed to examine the relationship between self-control and online shopping consumptive behavior among female students living in the dormitory of Universitas Medan Area. The study employed a quantitative approach with a correlational research design. The population consisted of dormitory students, with a sample of 67 students selected using purposive sampling techniques. Data were collected using psychological scales, namely a self-control scale and an online shopping consumptive behavior scale, both constructed using a Likert scale format. Data analysis was conducted using the Pearson Product Moment correlation technique. The results revealed a significant negative relationship between self-control and online shopping consumptive behavior (r = -0.54; p < 0.05). These findings indicate that higher levels of self-control are associated with lower tendencies toward consumptive online shopping behavior. Conversely, students with lower self-control are more likely to engage in consumptive behavior in the digital era.

Abstract

Teachers’ career development has become increasingly important in contemporary educational systems due to growing professional demands and institutional transformation. Drawing upon Holland’s RIASEC theory and person–environment fit perspectives, this study examined the relationship between vocational interest congruence and teachers’ career development through the mediating role of job satisfaction and the moderating role of organizational support. A quantitative cross-sectional design was employed involving 412 secondary school teachers from public and private educational institutions. Data were collected using standardized self-report instruments and analyzed using structural equation modeling and PROCESS Macro Model 14. The results indicated that vocational interest congruence positively predicted teachers’ career development both directly and indirectly through job satisfaction. Teachers who perceived stronger alignment between their vocational interests and professional roles reported higher levels of job satisfaction, which subsequently enhanced professional career growth. Furthermore, organizational support significantly moderated the relationship between job satisfaction and career development, such that the positive effect became stronger under conditions of high organizational support. The moderated mediation analysis further demonstrated that the indirect effect of vocational interest congruence on career development through job satisfaction was substantially stronger among teachers perceiving greater institutional support. The study extends Holland’s RIASEC theory by demonstrating that teachers’ career development emerges through interactions between vocational alignment, psychological experiences, and organizational conditions. Practically, the findings highlight the importance of aligning teachers’ vocational characteristics with supportive institutional environments to promote sustainable professional development.

Abstract

Increasing demands in the workplace require employees to maintain their psychological well-being and work ability to sustain job performance. This study aims to integrate Islamic Work Ethics (IWE) and organizational psychology by examining the mediating role of psychological well-being in the relationship between IWE and work ability. A quantitative descriptive-correlational design was employed, involving 350 employees from various occupational functions. Data were collected using standardized instruments measuring IWE, psychological well-being, and work ability. The data were analyzed using descriptive statistics, Pearson's correlation, and regression-based mediation analysis. The findings indicate that IWE is positively associated with both psychological well-being and work ability. Psychological well-being also demonstrates a significant positive association with work ability. The mediation analysis further reveals that psychological well-being partially mediates the relationship between IWE and work ability, suggesting that ethical values are associated with work ability through both direct and indirect psychological pathways. These findings indicate that IWE can be conceptualized as a value-based psychological resource. From a practical perspective, the results highlight the importance of integrating ethical values into human resource management practices to enhance employee well-being and sustain work ability over time.
