\begin{abstract}
Flow and optimism are found to be both independently associated with
psychological well-being. However, there hasn't been a thorough analysis
of optimism's mediating function in this relationship. To conduct a
thorough analysis of peer-reviewed research on optimism's role as a
mediator between flow and psychological health in adults between the
ages of 18 and 65. PRISMA 2020 guidelines were adhered to in this
systematic review. To find studies published between 2015 and 2025, six
databases were searched: PsycINFO, Scopus, PubMed, Google Scholar,
ScienceDirect, and ERIC. The following criteria must be met for
inclusion: statistical mediation analysis of optimism between flow and
well-being, adult samples, empirical research, and English language
proficiency. To evaluate quality, the Mixed Methods Appraisal Tool
(MMAT) was employed. Nine studies satisfied the requirements for
inclusion. Research indicates that optimism mediates the relationship to
some extent, particularly when it comes to stress, academic motivation,
and job satisfaction. However, generalizability is constrained by
measurement and design heterogeneity. Flow and psychological health are
significantly mediated by optimism. Implications for interventions, both
theoretical and practical, are examined. It is advised to conduct more
longitudinal and cross-cultural research.%
