The single parent who has to assume the role and the responsibilities of both mother and father provides a different sex-role model for the child than that provided in the two-parent family. Research has indicated that single parents are more androgynous than parents in intact families. To investigate the sex roles of 332 college students (213 females; 119 males) who were raised in single parent (N=48) and intact nuclear families (N=284), the BEM Sex-Role Inventory, the Spence-Helmreich Personal Attributes Questionnaire, the Family Environment Scale--Short Form, and the Marital History Survey were administered. An analysis of the results showed that children reared in a single-parent environment did not differ substantially from those reared in a nuclear parent home on scales measuring androgyny. However, single-parent family environments did produce a significant change in the distribution of sex-role types, i.e., androgynous males appeared more frequently in single-parent families, while androgynous females appeared less frequently; undifferentiated males appeared less frequently and undifferentiated females appeared more frequently. Neither age nor maternal employment were found to be significant factors determining androgyny. (BL)
