The Relation of Self-Reported Abilities to Aptitude Test Scores: A Replication and Extension

Scales from the Self-Directed Search (SDS) were correlated with those of the Ball Aptitude Battery (BAB) for a sample of 198 high school students. The present study found larger canonical correlations between the SDS and aptitude measures than those reported by Kelso, Holland, and Gottfredson (1977). However, the variance across the data sets associated with these canonical correlations was minimal, and much of the shared variance associated with the BAB canonical variates was due tog, with specific abilities contributing only minor portions of the observed shared variance.
