Previous research has yielded mixed results about the relationships between intensive parenting attitudes and parental emotions. Further, very few studies have investigated the indirect effects of intensive parenting attitudes on parental anger through parental emotion regulation. In this study, we aim to understand the direct and indirect relationships among these variables, particularly focusing on essentialism and fulfillment and orientation to a child's emotions and emotional lack of control. Results from 654 parents with diverse racial backgrounds indicated that essentialism and fulfillment were significant predictors of parents' use of two dimensions of emotion regulation and that both dimensions were significant predictors of parental anger expression. While emotional lack of control was a significant predictor of parental anger experience, orientation was not. Mediation analyses showed that orientation was a positive mediating emotion regulation between essentialism and anger expression but a negative mediating emotion regulation between fulfillment and anger expression. Emotional lack of control was a positive mediating emotion regulation between essentialism and two anger dimensions but a negative mediating emotion regulation between fulfillment and two anger dimensions. We discussed all these results under the counseling context of helping parents regulate their anger.
