This study investigates the interplay between insecure attachment styles, materialism, and phubbing behaviors. Phubbing, the act of ignoring a partner in favor of smartphone use, is influenced by individual differences and societal norms. We hypothesized that attachment anxiety and avoidance would be positively associated with both enacted and perceived phubbing, and that materialism would mediate these relationships. Data were collected from 213 participants using validated scales for attachment, materialism, and phubbing. Results confirmed that attachment anxiety is positively associated with both enacted and perceived phubbing, while attachment avoidance is positively associated with perceived phubbing but not enacted phubbing. Materialism was found to mediate the relationship between attachment insecurity and phubbing behaviors. Specifically, materialism significantly mediated the positive relationships between attachment anxiety and both enacted and perceived phubbing, as well as between attachment avoidance and perceived phubbing. These findings suggest that materialistic values amplify the effects of insecure attachment on phubbing, highlighting the role of materialism as a compensatory mechanism for attachment-related insecurities. Future research should explore interventions targeting materialism and attachment anxiety to mitigate phubbing behaviors and improve relationship quality.
