The study examined the differential validity of 20 male and 14 female biographical subgroups in terms of 12 factor analyzed dimensions of postcollege experience. Owens' Developmental‐Integrative Model hypothesizes that different subgroups of individuals with similar within‐group early life experiences should exhibit significant differences (between‐group) in a wide variety of life experiences. A sample of 1428 first‐year college students were statistically grouped into 23 male and 15 female biodata subgroups after completing a standardized 118‐item biodata form (Owens, 1968). Seven years later, a 97‐item post‐college experience inventory obtained scores for 484 of the original subjects on 12 factors of post‐college behavior including job satisfaction, transition from college, personal and marital adjustment, and others. Significant univariate and multivariate differences were found between the biodata subgroups across the 7‐year period. Implications for the validity of the D‐I model are offered.
