To assess relationships between parental socialization of emotion and children's coping following an intensely emotional event, parents' beliefs and behaviours regarding emotion and children's coping strategies were investigated after a set of terrorist attacks. Parents (n = 51) filled out the Parents' Beliefs about Negative Emotions questionnaire and were interviewed within two weeks of the attacks. Their elementary and middle school-aged children were interviewed eight weeks later. First, parents' beliefs were related to two kinds of parental behaviours. Parents' beliefs about both the value of and the danger of children's emotions were positively related to their discussion with their children. Parents' belief about children's emotions as dangerous was also negatively related to parents' expressiveness with their children. Second, parents' beliefs were related to five kinds of coping strategies reported by their children. Parents' belief about children's emotions as valuable predicted children's problem-solving, emotion-oriented, and support-seeking coping following the terrorist attacks. Parents' belief about children's emotions as dangerous predicted children's avoidance and distraction coping following the attacks. Parents' beliefs about the importance of children's emotions may foster a family atmosphere that facilitates children's coping with intensely emotional events. Results support differentiated, multi-faceted analysis of the broader construct of parental beliefs. (Contains 1 figure, 3 tables, and 1 note.)
