Lung cancer stigma is a predictor for psychological distress: A longitudinal study. Lung cancer stigma is a predictor for psychological distress.

Objectives: To examine if baseline stigma predicts psychological distress at 3 and 6 months follow-up among patients newly diagnosed with lung cancer.

Methods: This longitudinal study was nested within a larger randomised controlled trial. Eligible participants were recruited via respiratory and oncology out-patient clinics in Australia (n = 194). Consenting participants were asked to complete surveys at baseline, 3 and 6 months post-recruitment. Measures included lung cancer stigma (Cataldo Lung Cancer Stigma Scale) and psychological distress (General Health Questionnaire-12 [GHQ-12]).

Results: One-hundred and ninety-four participants were included for analysis. Most were male (57.7%) with a mean age of 68 years (SD = 8.8). A significant relationship between baseline lung cancer stigma and psychological distress at 6 months was found, where a one unit increase in lung cancer stigma increases psychological distress by 0.044 when adjusting for age, gender, smoking status, baseline GHQ-12 scores and intervention allocation (as part of the larger trial; p = 0.001; β = 0.044, 95% CI = 0.010, 0.079).

Conclusion: Temporal links between lung cancer stigma and psychological distress was found at 6 months, suggesting stigma-related experiences may have a delayed impact. Development of routine lung cancer stigma assessments is recommended to identify those at risk of psychological distress.
