University students often encounter various academic and personal challenges that may affect their
psychological functioning. Subjective well-being is a crucial psychological resource that helps
individuals cope with these challenges. Among the key factors influencing subjective well-being are
social support and positivity. This study examines the moderating role of positivity in the
relationship between social support and subjective well-being. Using a quantitative correlational
design, data were collected from 416 university students through three validated instruments: the
Social Support Scale, the Positivity Scale, and the Subjective Well-being Scale. The data were
analyzed using moderated regression analysis. Results revealed that social support and positivity
were positively and significantly associated with subjective well-being. Moreover, positivity
significantly moderated the relationship between social support and subjective well-being. The
simple slope analysis shows that at a high positivity level (+1 SD), the estimated effect of social
support on subjective well-being was 0.296 (SE = 0.0344, Z = 8.62, p < 0.001). This shows that
positivity strengthens the relationship between social support and subjective well-being
