Passive social media use often elicits upward social comparison, but its psychological impact depends on the comparison mode—assimilative versus contrastive. This study identifies individual factors that predict which mode young adults adopt. Data from 462 U.S. users show that trait self-compassion fosters self-improvement (over self-destruction) motivations, which in turn promote assimilative comparisons and positive well-being. Conversely, self-destruction motivations drive contrastive comparisons, yielding negative well-being. These findings clarify that passive exposure is not uniformly harmful; rather, outcomes are contingent on stable traits and motivational orientations. Interventions cultivating self-compassion and redirecting motives toward improvement may help safeguard young adults’ mental health in digital environments.
