Interventions to Reduce Lung Cancer and COPD-Related Stigma: A Systematic Review

Background
Many individuals with lung cancer and chronic obstructive pulmonary disease (COPD) experience high levels of stigma, which is associated with psychological distress and delayed help-seeking.

Purpose
To identify interventions aimed at reducing the stigma of lung cancer or COPD and to synthesize evidence on their efficacy.

Methods
A systematic review was conducted by searching PubMed, Scopus, PsycINFO, and CINAHL for relevant records until March 1, 2024. Studies were eligible if they described an intervention designed to reduce internalized or external stigma associated with COPD or lung cancer and excluded if they did not report empirical findings.

Results
We identified 476 papers, 11 of which were eligible for inclusion. Interventions included educational materials, guided behavior change programs, and psychotherapeutic approaches. Interventions targeted people diagnosed with, or at high risk of developing COPD or lung cancer or clinical staff. No interventions that aimed to reduce stigma associated with lung cancer or COPD in the general community were identified. Most interventions yielded a statistically significant reduction in at least one measure of stigma or a decrease in qualitatively reported stigma.

Conclusions
The emerging literature on interventions to reduce stigma associated with lung cancer and COPD suggests that such interventions can reduce internalized stigma, but larger evaluations using randomized controlled trials are needed. Most studies were in the pilot stage and required further evaluation. Research is needed on campaigns and interventions to reduce stigma at the societal level to reduce exposure to external stigma amongst those with COPD and lung cancer.
