Adolescents’ body image trajectories: A further test of the self-equilibrium hypothesis.

= 12.6, including 541 males and 465 females) across a 4-year period. The results supported the self-equilibrium hypothesis among 3 profiles of adolescents, all characterized by matching BI levels and stability: (a) High (48.0%); (b) Increasing (34.1%); and (c) Decreasing (17.9%). Boys presented higher levels of BI, and the quality of relationships with peers and parents predicted initially more desirable trajectories across gender. By the end of the study, more positive academic outcomes were associated with the Decreasing profile, lower internalizing problems with the High profile, and lower externalizing problems with the High and the Increasing profiles.
