ABSTRACT
This study presents a meta-analysis assessing the antecedents that are associated with the influence that advertising and friends' behaviours have on the formation of materialistic behaviours in youth. We carried out a systematic review in which we identified an initial 217 studies. Of these, 32 were ultimately included in the analysis. Our results revealed significant relationships for the constructs associated directly with susceptibility to advertising (advertising viewing attitudes, attention to advertising, celebrity endorsements in advertising, advertising exposure and TV viewing frequency) and for perceived friends' norms (friends' attitudes, social comparisons with friends and communication with friends) with materialism in youth.
