This study investigated the relationship between job involvement and three sets of variables: nine personal (age, sex, marital status, education, overall experience, nonteaching experience, present school experience, income, and locus of control), three structural (size of school, location of school, and hierarchical position), and eight job factors (overall job satisfaction, satisfaction with supervision, satisfaction with coworkers, participation in decision-making, job motivation, closeness of supervision, consideration, and initiating structures). Data were obtained from 838 elementary and 975 secondary teachers in Ontario. Although bivariate correlations generally supported the hypothesized predictions, multiple regression analysis indicated that involvement is mainly related to three variables: job motivation, job satisfaction, and marital status. Three other variables--participation in decision-making, educational level, and satisfaction with supervision--were only significantly related to involvement for secondary teachers. The independent variables explained about 22 percent of the variance in job involvement for elementary teachers and 29 percent for secondary teachers. When the results were analyzed by sets of variables, it was found that job factors were the only ones related to involvement for both samples. The results are discussed and compared with earlier findings and implications for future research are suggested. (Author/IRT)
