Time Since Menarche and Sport Participation as Predictors of Self-Objectification: A Longitudinal Study of Adolescent Girls

This study aimed to prospectively examine the role of time since menarche and sport participation in the development of self-objectification
in adolescent girls. Participants were 141 female adolescents (M = 14.45 years at Time 1) from Adelaide, South Australia, who completed questionnaires at two time points, approximately 1 year
apart. Self-report measures of menarcheal status and onset of menarche, time spent on organised sports, self-objectification,
body shame and disordered eating were completed at both time points. Time since menarche was not shown to relate to self-objectification.
However, correlations and structural equation modelling revealed that amount of sport was negatively related to later self-objectification.
That is, time spent playing sport was predictive of lower self-objectification 1 year later. In addition, the model of objectification
was confirmed at two time points providing important evidence for the stability of the model during adolescence. The results
provide the first empirical evidence for sport as a potential protective factor to the development of self-objectification
in adolescence and provide an important practical suggestion for one way in which girls can attempt to alleviate the development
of self-objectification and its harmful consequences.
