The major purpose of this summative evaluation study was to determine the effectiveness of an instructional intervention on adolescents' knowledge and perspectives using the curriculum Balancing Work and Family Life. The second purpose of the study was to determine the relationship of selected demographic and self-concept characteristics on adolescents' knowledge and perceptions of work and family roles. A nonequivalent control group research design was used;The sample for the study consisted of 166 adolescents in six vocational home economics programs in Iowa during the spring of 1989. Four instruments, including Work And Family Knowledge Test (WFKT), Future Likelihood Inventory (FLI), Self-description Questionnaire (SDQIII), and demographic questionnaire, were used for the study;Analysis of covariance (ANCOVA) procedures with WFKT pretest as covariate were used to determine the effects of the curriculum on adolescents' knowledge in the treatment and control groups. The results showed a statistically significant difference (p ≤.01) between the two groups, with treatment group scoring higher on WFKT posttest;Factor analysis procedures were used to identify dimensions of the FLI posttest. The results showed that six factors emerged: marital status, parental status, cohabitation, workplace characteristics, benefits of work, and flexible work schedule. These factors had coefficient reliability estimates of.69,.80,.57,.79,.68, and.44, respectively. The results of univariate analyses of variance showed a statistically significant difference (p ≤.05) between groups for the marital status factor;The results of multiple regression analyses procedures for selected demographic variables, self-concept factors, and Future Likelihood Inventory factors on adolescents' knowledge and perceptions of work and family roles, found that parental influence, self-aspirations, gender, current work status, socio-economic status and others' aspirations were demographic variables that were significantly related to adolescents' knowledge and perceptions of work and family roles. Flexible work schedule (a FLI factor), general self-concept, relationship with the opposite sex, and honesty (self-concept factors) were significantly related to adolescents' knowledge and perceptions of future work and family roles.
