This study examined the relationships among satisfaction with family function and emotional states of a nonprobability sample of sixty-six myocardial infarction (MI) patients and their spouses who were recruited from hospitals in the Delaware Valley. Patients and spouses completed the Family APGAR and the Affects Balance Scale. It was found that both patients and spouses experienced substantial emotional distress when compared with the norms for nonclinical subjects. They were highly correlated on both measures, particularly for positive emotion and satisfaction with family function (p < .0001). Satisfaction with family function was significantly correlated with positive affect for spouses (p < .05). These results suggest the importance of assessment of satisfaction with family function and emotional status of both MI patient and spouse, with spouses with lower satisfaction with family function being at greater risk for emotional distress.
