A Short-Term Longitudinal Study of Pubertal Change,Gender, and Psychological Well-Being of Mexican Early Adolescents

This study examined the role of pubertal development on depression, externalizing behavior problems, self-esteem, and body-image of 951 Mexican early adolescents. The 5th through 7th grade students were assessed at the beginning and end of the school year. The main finding of this study is that the acute experience of menarche adversely affected Mexican adolescent girls psychological well-being, most specifically in terms of depressive symptomatology. On the other hand, pubertal change in Mexican boys, as measured by voice-change, did not appear to adversely affect psychological well-being above and beyond a nonsignificant minimal and temporal readjustment and in fact had a positive effect on body-image. Results suggest that perceived maternal control, prior social–emotional adjustment, and menstrual attitudes may moderate the effects of pubertal change.
