This study investigated how parental beliefs about children's emotions and parental stress relate to children's feelings of security in the parent-child relationship. Models predicting direct effects of parental beliefs and parental stress, and moderating effects of parental stress on the relationship between parental beliefs and children's feelings of security were tested. Participants were 85 African American, European American, and Lumbee American Indian 4th and 5th grade children and one of their parents. Children reported their feelings of security in the parent-child relationship; parents independently reported on their beliefs and their stress. Parental stress moderated relationships between three of the four parental beliefs about the value of children's emotions and children's attachment security. When parent stress was low, parental beliefs accepting and valuing children's emotions were not related to children's feelings of security; when parent stress was high, however, parental beliefs accepting and valuing children's emotions were related to children's feelings of security. These findings highlight the importance of examining parental beliefs and stress together for children's attachment security. (Contains 3 figures, 2 tables, and 5 notes.)
