Everyday emotion word and personal pronoun use reflects dyadic adjustment among couples coping with breast cancer

Dyadic adjustment is integral for couples facing breast cancer; therefore, it is important to identify its everyday indicators. A total of 52 couples coping with breast cancer wore the Electronically Activated Recorder (EAR) for one weekend and completed the Dyadic Adjustment Scale to investigate how dyadic adjustment manifests in noncancer-related word use. Multilevel models revealed that partners', rather than one's own, positive emotion words positively related to dyadic adjustment. Conversely, spouses' negative emotion words and patients' anger words were negatively related to dyadic adjustment. Furthermore, focus on spouses rather than patients (spouses “I” and patients “you”) positively related to dyadic adjustment. Results revealed that dyadic adjustment can be reflected in couples' everyday word use, serving as an objective indicator of marital quality.
