The effects of spousal interactions on affect and next-day somatic symptoms

The present study examined daily survey data collected from married couples over the course roughly 14 days. I investigated the relationships of the morning quality ratings of three distinct spousal interactions conversation (physical affection, and sexual activity) reported in mornings on later-day positive and negative affect, as well as next-day intensity of negative somatic symptoms (e.g. headaches, dizziness, aches and pains). Hierarchical linear modeling was used to estimate path models for both husbands and wives. Direct and indirect effects were observed. Results showed that quality of conversation and physical affection increased later-day positive mood for both husbands and wives; however, positive quality activity increased later-day positive affect for wives only. Quality of sexual activity decreased later-day negative affect for wives only. Less later-day negative affect decreased next-day intensity of symptoms for both husbands and wives. Lastly, quality of sexual activity decreased later-day negative affect, which decreased next-day somatic symptoms for wives. This was the only significant indirect effect. Implications are that high marital quality is important for maintaining psychological health for both spouses, and physical health, particularly for wives.
