Background　and　Objectives:　During　large-scale　stressful　events　such　as　pandemics,　situational　uncertainty　and　daily　routine　disruptions　increase　anxiety　prevalence,　underscoring　the　need　for　research　on　approaches　to　promote　effective　coping.　This　study　focused　on　the　psychological　function　of　benefit　finding　in　the　context　of　the　COVID-19　pandemic.　Design　and　Methods:　Both　Study　1a　(a　cross-sectional　survey　of　567　Chinese　adults)　and　Study　1b　(a　two-wave　longitudinal　survey　of　406　Chinese　adults)　examined　the　relationship　between　benefit　finding　and　anxiety,　with　hope　as　the　mediator.　Study　2　used　an　interventional　design　to　examine　the　efficacy　of　daily　benefit-finding　writing　among　129　Chinese　college　students.　Results:　In　Studies　1a　and　1b,　benefit　finding　was　positively　associated　with　anxiety,　which　was　mediated　by　hope.　Study　2　showed　that　daily　writing　tasks　significantly　promoted　benefit　finding.　Hope　mediated　the　relationship　between　benefit　finding　and　anxiety　at　both　the　within-　and　between-person　levels.　Conclusions:　Benefit　finding　can　foster　hope　and　relieve　anxiety.　Daily　benefit-finding　activities,　which　can　be　conducted　online,　can　help　improve　mental　health　during　pandemics.　©　2024　Informa　UK　Limited,　trading　as　Taylor　&　Francis　Group.
