The purpose of the study is to explore factors related to the outcomes of parenting education groups. Participants in the study included 386 parents who attended 30 parenting education groups in the greater Taipei area. A questionnaire was designed for the study to measure the outcomes of the parenting education group. Participants completed the questionnaire at the end of the parenting education programs. Among 11 predictive variables, 5 variables (number of absence, member interaction, leader-member interaction, participation willingness, and group expectation) were significantly related to parenting education outcomes. Multiple regression analysis was conducted using these five variables as predictors and parenting education outcomes as the criterion variable. Results indicated that group expectation, number of absence, leader-member interaction, and participation willingness were all significant predictors of parenting education outcomes. A total of 35% of the variance of the dependent variable was explained by the regression equation.
