114 biologically related families and 109 adoptive families were administered the Strong-Campbell Interest Inventory. The protocols of 870 parents and their adolescent children were scored on the 6 scales of J. L. Holland's model of interest styles (Realistic, Investigative, Artistic, Social, Enterprising, and Conventional). Biological parent-child correlations ranged from -.13 to +.40, with 15 of the 24 scale correlations achieving significance; only 2 of the adoptive parent-child correlations were significant (range from -.15 to +.25). Biologically-related pairs were also significantly more correlated than adoptive pairs for interest profiles. Same-sex biological siblings were more similar to each other than either opposite-sex sibling pairs or parent-child pairs. Pairs of unrelated children in the adoptive families were not too similar either on Holland's scales or the profile analysis. (28 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
