Types produce types: An examination of personality development using Holland's theory

This study was designed to test Holland's hypothesis that parents encourage the development of their own personality types in their offspring. Data were collected by personal interviews from three freshmen classes at a large midwestern university. Parent's personality types (occupations) were compared to offsprings' personality types (expressed occupational choices) using the Kolmogorov-Smirnov one-sample test to determine whether or not the comparisons were due to chance. The results indicated that relationships existed between the personality types of fathers-sons, fathers-daughters and mothers-daughters while no relationship was confirmed between mothers-sons.
