Laursen, Brett, Boivin, Michel, Brendgen, Mara, Dickson, Daniel J., Bowker, Julie C. et Rubin, Kenneth H. 2021. «Revisiting the Hypothesis that Friends Buffer Against Diminished Self-Esteem Arising from Poor Quality Parent-Adolescent Relationships: A Replication Study ». Developmental Psychology, vol. 57, no 12, p. 2067-2081.
Concerning previous studies that suggest that «support from friends buffers against diminished self-esteem arising from poor quality relationships with mothers during the transition into adolescence, [t]he aim of this replication study was to conduct an independent test of these findings with both concurrent and longitudinal data.» (p. 2067)
The authors revisit a previous hypothesis that suppose that «[s]upport from friends buffers against diminished self-esteem arising from poor quality relationships with parents.» (p. 2068)
Data for this study were dawn from four different projects. About the first sample, «[d]ata were drawn from a population-based sample of 662 twin pairs from the greater Montreal (Canada) area, who were recruited at birth between November 1995 and July 1998 […].» (p. 2070) Data of the second sample «were drawn from a multicohort longitudinal study of 1333 participants from the greater Washington, DC area, who were recruited in 1999 and 2000.» (p. 2071) About the third sample, data «were drawn from a longitudinal study involving 313 adolescents (126 boys, 187 girls) and their mothers from the greater Miami, Florida area, who were recruited in 1998 […].» (p. 2071) Finally, data of the fourth sample «were drawn from a longitudinal study involving 232 adolescents (118 boys, 114 girls) and their mothers from the greater Montreal, Canada area, who were recruited in 2006.» (p. 2072)

«Data from multiple studies, analyzed collectively and separately, were unable to replicate previous findings suggesting that friend social support moderates associations between mother–child relationship quality and concurrent adolescent self-esteem. Not only did the hypothesized moderated associations fail to reach conventional levels of statistical significance, but the magnitude of the effects obtained in the replications were considerably smaller than in the originals. Put simply, we could not substantiate claims that positive relationships with friends buffer against diminished self-esteem arising from poor relationships with parents.» (p. 2077-2078) However, results show «that friend support and mother support were concurrently associated with self-esteem, as reported in the original studies. These main effects are consistent with a cumulative effects model, in which each relationship makes a unique, independent contribution to adolescent well-being.» (p. 2078)
