In this study, we examined whether regular divorces can be distinguished from complex divorces by measuring the intensity of negative emotions that divorced parents report when thinking about their ex-partner. We recruited two groups of parents: n = 136 in a regular divorce, and n = 191 in a complex divorce. Based on the existing literature, we predicted that parents in complex divorces experience more intense negative emotions than parents in regular divorces; especially emotions that motivate emotional distancing (contempt, disgust, anger, hatred, and rage) and emotions that impair self-regulation (fear, shame, guilt, and sadness). We also predicted that these emotions would hamper co-parenting, particularly in complex divorces. The results provided support for our predictions, except for fear and sadness. We found that parents in a complex divorce reported more co-parenting concerns than parents in a regular divorce. In contrast to our expectations, the relation between negative emotions and coparenting concerns was stronger among parents in a regular divorce than in a complex divorce. These findings underline the importance of emotions in the divorce trajectory and suggest that especially the intensity of emotional distancing emotions may serve as a screening tool to identify parents at risk for a complex divorce
