The effect of parental divorce on discomfort and cardiac activity in response to public displays of affection in college females

Two studies examined the effect of parental divorce on feelings of discomfort and cardiac activity in response to public displays of affection (PDAs). In the first study, females from divorced homes reported marginally significant higher discomfort in response to PDAs than females from intact homes. In the second study, 32 female participants (16from divorced homes and 16from intact homes) viewed a PDA video and a control video and subsequently were asked to complete the same measure of discomfort as in Study 1. Interbeat intervals (IBIs) were recorded, and mean IBI and respiratory sinus arrhythmia (RSA) were derived. IBI and RSA increased in both groups in response to the videos over baseline. No differences were found between the divorce and intact groups for responses to the PDA video. However, the divorce group had higher heart rates and lower RSA overall, which suggests a potential mechanism for the association between divorce and negative physical health outcomes in women. Future studies should examine mediators of the relationship between divorce and reactions to PDA, such as marital conflict and parenting quality.
