Causal attributions and their impact on psychosocial functioning in head and neck cancer patient-caregiver dyads: a preliminary, longitudinal study.

Purpose: This longitudinal study explores causal attributions in newly diagnosed head/neck cancer (HNC) patients and their caregivers.
Methods: Perceptions of causal attributions and associated level of responsibility regarding each patient's HNC diagnosis at baseline (n = 72 dyads) were described and then tested as predictors of depressive symptoms, cancer worry, and perceived support 6 months later.
Results: When causes were reported, tobacco and alcohol use topped the list of both patients and caregivers. Three-quarters of dyads agreed about perceptions of the patients' responsibility in causing their HNC. Some dyad-level patterns of causal attribution were associated with patients' and caregivers' cancer worry (p < 0.05) and caregivers' perceived support (p < 0.05) in unadjusted models.
Conclusions: This preliminary study indicates that causal attributions warrant further exploration in HNC patient-caregiver dyads specifically, as well as studies of quality of life in patient-caregiver dyads more broadly considered.
