Reciprocal effects of self-concept and academic achievement in sixth and seventh grade

We aimed to (a) assess causal influences of three levels of self-concept on each other, (b) examine the relationship between each level of self-concept and academic achievement, and (c) compare the effect of self-concept on achievement with the effect of achievement on self-concept. In a two-year longitudinal study of 322 sixth and seventh grade students, influences over time between three levels of self-concept were weak. Zero-order correlations between self-concept and grades were positive and substantial, as in past studies. When using structural equation models, we found much weaker paths between self-concept and grades. Influences from self-concept to grades were very weak, but grades had a modest influence on subsequent discipline-specific self-concept. We conclude that past correlational studies have overstated the influence of self-concept on grades and of grades on self-concept.Financial support was supplied by the Life Cycle Institute, Catholic University.Received Ph.D. from Harvard University.

Child sexual abuse and pornography: Is there a relationship?

Sexual abuse is now a major form of child maltreatment; however, the causes of such exploitation are obscure. A review of official reports and other research indicate that the circumstances surrounding sexual abuse are inadequately specified to allow specific causal interpretations. The role of pornography in contributing to such abuse is explored by reviewing laboratory studies and the circumstances of child sexual abuse. An assessment of the research literature suggests that pornography is a minor and indirect influence on child sexual maltreatment.
