Further, a relationship has been documented between broader psychological adjustment, not just that within the school arena, and adolescents' educational aspirations and expectations. For instance, Trusty and Harris (1999) examined a national sample of 8th graders, all of whom expected to attend college at the start of the study. They found that girls in their sample who held a more external locus of control (i.e., felt that more things in their lives were outside their own control) were more likely to have decreased educational expectations between 8th grade and 2 years out of high school than girls with a more internal locus of control.
