Objective: To investigate associations between markers of social functioning (trouble with social eating and social contact), depression and health-related quality of life (QOL) among head and neck cancer survivors.Methods: This cross-sectional analysis included individuals with oral cavity, oropharynx, larynx, salivary gland and thyroid cancers from Head and Neck 5000 alive at 12 months. Trouble with social eating and social contact were measured using items from EORTC QLQ-H&N35 and QOL using EORTC QLQ-C30; responses were converted into a score of 0-100, with a higher score equalling more trouble or better QOL. A HADS subscale score of ≥8 was considered significant depression.Associations between tertiles of trouble with social eating and social contact and depression and QoL were assessed using multivariable logistic and linear regression (with robust errors), respectively.Results: Of 2561 survivors, 23% reported significant depression. The median QOL score was 75.0 (interquartile range 58.3-83.3).
