Research Findings: Emotional and social competence are critical to a child's current and future well-being. A. D. Paterson et al. (2012) studied a sample of mothers and proposed that an adult's approach to the socialization of a child's emotions can be summarized in his or her parenting style as measured by the Emotion-Related Parenting Styles (ERPS) scale. These styles are emotion approving, emotion disapproving, active socialization, and uncertain/ineffective socialization of negative emotions. This study aimed to determine whether the ERPS scale is a reliable measure of the emotion socialization styles of parents and non-parents of both genders. Participants were 521 undergraduate students - males (n = 76), females (n = 445), parents (n = 290), non-parents (n = 231) - with a mean age of 32.26 years (SD = 9.92, range = 18-61 years). There were no significant differences between the ERPS subscale scores of parents and non-parents, but males and younger adults showed higher disapproving and uncertain responses. The factor structure of the ERPS was confirmed for females. One factor was found to be unreliable for males. Practice or Policy: The ERPS is a reliable measure of the emotion socialization styles of females. Further research is required to establish the scale's reliability with males.
