Abstract
ABSTRACT
This application is being submitted in response to the Notice of Special Interest (NOSI) identified as
NOT-CA-21-026. Cancer stigma presents a key barrier to cancer control and prevention efforts globally, but
especially in low- and middle-income countries (LMICs) and among populations who are at high risk for cancer
such as people living with HIV/AIDS (PLWH) and those who smoke. Cancer and cancer stigma’s
disproportionate impact on people in LMICs and PLWH warrants intervention to reduce cancer stigma and
increase engagement in cancer prevention and care for PLWH living in LMICs; however, little to no research
has investigated the unique aspects of cancer stigma among PLWH in an LMIC. In this supplemental study,
which is integrated into a three-arm tobacco cessation implementation-effectiveness randomized control trial
among PLWH in Viet Nam, we propose to develop a multi-component cancer stigma scale for use among
PLWH in an LMIC context. First, a qualitative investigation will be conducted to understand how cancer
stigma—and specifically lung cancer stigma—manifests among two groups of PLWH at differentially
augmented risks of cancer: PLWH who smoke and PLWH who do not smoke. In this investigation, three
theorized components of cancer stigma (i.e., public, internalized, and enacted stigma) and related concepts
such as cancer awareness, intersecting stigmas such as HIV stigma and smoking stigma, and salient cultural
considerations will be explored. Findings from this qualitative work and cognitive interviewing will inform the
selection of items to create a multi-component cancer stigma scale that can be used among PLWH in Viet
Nam. The draft scale will be piloted among a sample of Vietnamese PLWH (N=100; n=50 PLWH who smoke
and n=50 PLWH who do not smoke). Pilot data will be used to conduct psychometric evaluation of the multi-
component cancer stigma scale and explore correlations and associations between cancer stigma, cancer
awareness, HIV and smoking stigma, and various related psychosocial and behavioral factors such as harmful
psychological symptoms (e.g., depression, anxiety), timing of health-seeking, HIV treatment adherence,
smoking cessation, cancer knowledge, and self-efficacy. Developing and validating a multi-component cancer
stigma scale in the context of Viet Nam in a way that accounts for culturally salient expressions of stigma is a
crucial step towards better understanding and addressing cancer stigma to promote cancer control and
prevention across diverse LMIC and low-resource settings.
