Research paper thumbnail of General Mental Health and Subjective Well-Being Among University Students: The Moderating Role of Personal Cultural Orientations

It additionally explored the moderating role of personal cultural orientations in the link between general mental health and subjective well-being. The findings indicated that general mental health was positively correlated with subjective well-being, independence, interdependence, tradition, and prudence, and negatively with power, risk aversion, and ambiguity intolerance. Similarly, subjective well-being showed positive associations with independence, interdependence, tradition, and prudence, while it was negatively linked to risk aversion and ambiguity intolerance. Moderation analyses revealed that independence, interdependence, and prudence enhanced the positive association between general mental health and subjective well-being among university students. The current findings add to the shortage of information available on the interaction between personal cultural orientations and general mental health in explaining subjective well-being in university students. Practical implications are also discussed.

Therefore, it is important to develop instruments to detect these incidents and understand the problem so as to design effective intervention strategies. Objective.-This study aims to construct a new self-report questionnaire, the Relational aggression scale (RAS), consisting of four subscales, namely direct, indirect, proactive and reactive RA, and to examine the factorial, convergent and criterion validity, the reliability (internal consistency and test-retest), and the measurement invariance of the instrument among Greek adolescents. Method.-The study uses a cross-sectional design. The RAS was administered to 1231 youth aged between 10 to 16 years old along with three self-reports of RA and antisocial personality traits. Results.-The findings confirmed the validity and reliability of two correlated two-factor models (i.e., direct and indirect RA, proactive and reactive RA) and a correlated four-factor model (i.e., proactive direct, proactive indirect, reactive direct, reactive indirect). Regarding convergent validity, the RAS scores were positively correlated with other RA measures, while concerning criterion validity, significantly positive associations emerged between RA and antisocial personality traits. The measurement invariance of the scale across both gender and grade level was also supported. Conclusion.-The RAS is a valid and reliable assessment instrument of RA during adolescence. Implications for the use of the RAS to assess direct, indirect, proactive, reactive forms of RA and inform intervention decisions in samples of youth are discussed.

Three aggression profiles emerged (i.e., low, combined, reactive) with the combined aggression group scoring higher on CU traits and MD than the high reactive and low aggression groups. Callous-unemotional traits and MD were positively associated with proactive and reactive aggression, while cognitive empathy was negatively associated with proactive aggression and MD. MD and cognitive empathy moderated the association between CU traits and proactive aggression, while affective empathy moderated the CU traits and reactive aggression link. The results highlight that MD and empathy are key factors in the association between aggression and CU traits in early adolescents. Practical implications are also discussed.
