Background: Lung cancer patients and their spouses may engage in blame attributions regarding the cancer cause, which may adversely affect their psychological adjustment.
Purpose: The aim of this study was to examine whether dyadic adjustment and network support moderate the association between blame and distress in couples affected by lung cancer.
Methods: Patients and their spouses completed questionnaires within 1 month of treatment initiation (baseline) and at 6-month follow-up.
Results: Multilevel modeling of data from 158 couples revealed that, at baseline, dyadic adjustment moderated the association between blame and distress for patients but not spouses (p < 0.05). Controlling for baseline distress, baseline blame predicted later distress (p < 0.05) for both patients and spouses regardless of dyadic adjustment. Network support moderated this association at follow-up.
Conclusion: For patients experiencing low dyadic adjustment, blame was associated with increased distress. Not initially but later, network support may protect against low levels but not high levels of blame in patients and spouses.
