Marital communication in eating disorder patients: a controlled observational study.

In order to investigate the communication between 21 eating disorder (ED) patients and their husbands, an observational study was carried out using two matched control groups of 21 maritally distressed (MD) and 21 nondistressed (ND) couples. During some discussion tasks the interaction was videotaped and the (verbal and nonverbal) communication skills were rated afterwards according to the Kategoriensystem für Partnerschaftliche Interaktion (KPI) coding system. Unexpectedly, compared with the control groups ED couples do not show a greater disequilibrium (between patient and husband) in the emission rate of positive and negative messages. Also striking is the generally higher degree of self-disclosure in ED couples than in ND couples, but this may reflect their experience of distress. Overall and most importantly, ED couples appear to lack some of the ND couples' skills of constructive communication, but manage to avoid the destructive communication style of MD couples.
