The current study examined the joint effect of personality and parenting factors on the prediction of bulimia nervosa (BN) and social anxiety disorder (SAD) symptomology in a sample of female college students. The study also tested whether personality and parenting factors might account for the association between BN and SAD symptoms.
One-hundred twenty-eight participants completed self-report measures assessing maternal care (MC), maternal overprotection, sensitivity to punishment (SP), sensitivity to reward (SR), and BN and SAD symptomology.
SP, SR, and MC each uniquely predicted BN symptoms, whereas only SP and MC predicted SAD symptoms. High SP interacted with low MC to predict BN and SAD symptoms over the main effects. In addition, SP, MC, and the interaction term SP x MC mediated the association between SAD and BN symptoms.
High SP and low MC appear to account for the link between BN and SAD symptomology, whereas high SR appears to distinguish the disorders.
本研究考察了人格因素和教养因素对女大学生样本中神经性贪食症（BN）和社交焦虑障碍（SAD）症状预测的联合效应。该研究还测试了人格因素和教养因素是否可能解释BN与SAD症状之间的关联。
128名参与者完成了自我报告测量，评估母亲关怀（MC）、母亲过度保护、惩罚敏感性（SP）、奖励敏感性（SR）以及BN和SAD症状。
SP、SR和MC各自独特地预测了BN症状，而只有SP和MC预测了SAD症状。高SP与低MC相互作用，在主要效应之外预测BN和SAD症状。此外，SP、MC以及交互项SP×MC介导了SAD与BN症状之间的关联。
高SP和低MC似乎解释了BN与SAD症状之间的联系，而高SR似乎区分了这两种障碍。
