Belief in a just world and meaning in life among Chinese adolescents: The mediating role of basic psychological need satisfaction

Previous literature has shown that adults with higher belief in a just world (BJW) experience greater meaning in life than those with less pronounced BJW. However, the role of BJW in adolescent meaning in life and the associated psychological mechanisms remain unclear. Thus, two studies were conducted to explore the roles of personal belief in a just world (PBJW) and general belief in a just world (GBJW) in meaning in life as well as the explanatory role of basic psychological need satisfaction among Chinese adolescents. Study 1 offered cross-sectional evidence that individuals higher in PBJW and GBJW displayed greater meaning in life, and basic psychological need satisfaction accounted for these associations. Study 2 provided longitudinal evidence that individuals higher in PBJW and GBJW at Time 1 exhibited greater meaning in life six months later (Time 2), wherein basic psychological need satisfaction at Time 1 served as a mediator. These findings contribute to understanding the adaptive benefits of PBJW and GBJW in meaning in life during adolescence and point to a crucial channel connecting BJW and meaning in life.
