                      aims of many strategies for the promotion of public mental
                      health. Such strategies become increasingly important since
                      many people worldwide suffer from psychological distress and
                      mental disorders, resulting in substantial individual and
                      societal costs. Within the last years, there is a shift from
                      strategies solely focusing on the reduction of mental
                      distress to those also aiming at the promotion of positive
                      mental states. Correlates, that is, psychosocial resources,
                      of positive mental states may represent a starting point for
                      those interventions. To date, a comprehensive systematic
                      review on those correlates is still missing as well as
                      knowledge on culture-related differences.A systematic review
                      and meta-analysis on the longitudinal link between
                      psychosocial resources (eg, income, optimism, social support
                      and community coherence) and hedonic and eudaimonic positive
                      mental states (eg, life satisfaction, happiness and
                      forward-looking attitude) will be conducted. Using
                      Hofstede's dimensions of culture and global metrics of
                      Education, Industrialisation, Richness and Democratic values
                      (EIRDness), we will examine culture-related moderators of
                      these associations. The systematic review will be conducted
                      following standards of the Cochrane Collaboration and will
                      be reported in accordance with the Preferred Reporting Items
                      for Systematic reviews and Meta-Analyse guidelines.
                      Literature searches for primary studies will be carried out
                      across four databases (APA PsycNet, Embase, Scopus and the
                      Web of Science Core Collection), including all publications
                      up to 27 January 2025. Screening at the level of titles and
                      abstracts will be performed with the help of artificial
                      intelligence software (ASReview). Study quality will be
                      assessed using an adapted version of the Newcastle Ottawa
                      Scale. We will employ multilevel meta-analyses of
                      correlation coefficients, with cultural variables being
                      examined as moderators.This systematic review does not
                      require ethics approval, as it solely uses previously
                      published data. Materials and data used for this review will
                      be shared via open repositories (https://osf.io/2xkhs/).
                      Results will be published in an international, peer-reviewed
                      journal and presented at conferences including plain
                      language summaries. OSF REGISTRATION DOI :
