Suicidal thoughts and behavior can begin early in childhood and are a leading cause of death in youth. Although specific mechanisms of risk remain largely unknown, theorists and researchers highlight the importance of the parent–child relationship. The current study focused on one aspect of this relationship: the dynamic exchange of facial affect during interactions. Specifically, we examined the relation between children's history of suicidal ideation (SI) and synchrony of facial expressions during positive and negative mother–child interactions.
