Until recently, most parent-child research has focused on the mother-child dyad or the father-infant or young child relationship. The present study investigated strengths of the father-young adult relationship with respect to the following variables: individuation, intimacy, intimidation, age, marital status, gender and birth order. College students at a large mid-Atlantic university and their fathers completed instruments regarding the above aspects of their relationship. The instruments administered were the Personal Authority in the Family System Questionnaire (PAFS-Q) and the Family Assessment Measure (FAM-III). Correlation, analysis of variance, and step-wise multiple regression were used for statistical analysis. Results indicated that fathers and young-adult children had significantly different perceptions of the dyadic relationship strength. There was a strong relationship between intergenerational individuation and intimacy with relationship strength. Birth order proved to be a significant factor in the assessment of intimacy, intimidation and relationship strength. Individuation and intimacy were the only variables that explained a Significant percentage of variance in dyadic relationship strength. Explanations for the findings, therapeutic implications, and suggestions for future research were explored. / Ph. D.
