Factors associated with psychological distress for couples facing head and neck cancer: A systematic literature review.

OBJECTIVES: Cancer patients in supportive relationships display improved health and survival outcomes. Identifying factors that might respond to intervention for Head and Neck Cancer (HNC) dyads is important as HNC patients and their partners experience heightened distress. This article systematically reviewed and evaluated the research findings and methodological quality of studies which identified factors influencing psychological distress for couples facing HNC. METHODS: PsycINFO, Medline, and CINAHL were searched. Studies were included if they used validated psychological distress measures and quantitative data collection methods. Eleven studies satisfied inclusion criteria. RESULTS: Studies identified factors associated with the psychological distress experienced by couples facing HNC, with substantial effect size variation. These factors included clinical, sociodemographic, relational, and psychological variables. Factors associated with increased psychological distress included disease burden, reduced social contact, perception of reduced relationship quality, and less adaptive/assimilative coping although the effect sizes displayed considerable heterogeneity. Overall, studies possessed good methodological quality but generally could have been improved by minimising the risk of non-response bias and fully reporting relational characteristics. CONCLUSIONS: The implications of these results for clinical practice and future research are discussed. Further research is recommended to report effect sizes more consistently for both dyad members to gain greater insight into couple-level distress and to perform moderator analyses to identify which variables influence the magnitude of psychological distress.
