The purpose of the study was to determine the attitudes of early adolescents toward single-parent and stepparent families. Objectives were to develop a valid and reliable instrument for determining early adolescents' attitudes toward single-parent and stepparent families; assess the attitudes of early adolescents toward single-parent and stepparent families; determine the relationship of the attitudes of early adolescents toward single-parent and stepparent families to sex, grade, place of residence, family structure, fathers' and mothers' occupation, and fathers' and mothers' education; and make recommendations for middle/junior high school curriculum;The questionnaire, "What I Think about Single-Parent and Stepparent Families," was a 39-item instrument developed by the researcher. The instrument was administered by school officials to 344 sixth, seventh, and eighth grade students randomly selected from 23 schools in Area Education Agency (AEA) 11 in Iowa. Usable data were obtained from 333 respondents;Data were analyzed using descriptive statistics, factor analysis, one way analysis of variance (ANOVA), and t-test. In general, respondents had neutral attitudes toward single-parent and stepparent families. Two factors emerged as a result of the factor analysis--Factor A: Feelings about Family Members and Factor B: Adjustment to Restructured Family. Except for father's occupation, no significant differences were found in attitude scores for the sociodemographic variables for Factors A and B. Significant differences in attitude scores by father's occupation were found for Factor B, with respondents from blue collar families having higher scores than those from white collar families. Recommendations were made for future research and for middle/junior high school curriculum.
