The present study evaluated a computer-mediated parent education program aimed at improving parents' self-concept and dysfunctional parenting practices.Employer-based parent education services were offered as part of a corporation's employee wellness program. Participants (N=247) were asked to complete pre- and post-test surveys including surveys of demographic information, parental self-concept, and dysfunctional parenting behaviors.Participants reported clinically significant levels of dysfunctional parenting practices at baseline. Results from the single-dose intervention indicated a significant decrease in hostile parenting from pre-test to post-test, which was likely predicted by parents' sense of competence at baseline.Computer-mediated parent education workshops were efficacious in improving parents' self-concept and reducing parents' use of hostile parenting tactics. The study provides an important contribution to the extant literature by documenting the effectiveness of computer-mediated parenting programs, particularly those offered through the workplace.
