Causal attributions and attitudes toward lung cancer

Stigma in Mexican patients with Lung Cancer: Psychometric Properties of the Cataldo Lung Cancer Stigma Scale (CLCSS) - Brief version

INTRODUCTION

Stigma in lung cancer patients may be associated with various negative outcomes such as increased psychosocial symptoms, severity of physical symptoms, and may act as a barrier to medical help-seeking behavior. The Cataldo Lung Cancer Stigma Scale (CLCSS) is one of the most widely used instruments for assessing health-related stigma in lung cancer patients.

OBJECTIVES

To determine the psychometric properties of the CLCSS in a Mexican sample of lung cancer patients.

METHODS

A non-experimental, instrumental design was employed, using non-probabilistic sampling based on availability. The sample included 265 lung cancer patients. Confirmatory Factor Analysis (CFA) was conducted to assess construct validity, and Cronbach's alpha and McDonald's Omega were used for internal consistency and test-retest reliability, respectively, through Pearson correlation coefficient.

RESULTS

The 17-item version yielded a model with 4 factors (stigma and shame, social isolation, discrimination, and smoking) explaining 50.74% of the variance, with adequate values of internal consistency and test-retest reliability.

SIGNIFICANCE OF RESULTS

The Mexican version of the CLCSS is culturally appropriate, brief, psychometrically valid, and reliable for assessing health-related stigma in Mexican lung cancer patients.

Examining evidence of lung cancer stigma among health-care trainees

BACKGROUND

Innovations in lung cancer control and care have started to transform the landscape of lung cancer outcomes, but lung cancer stigma and biases have been implicated as a deterrent to realizing the promise of these innovations. Research has documented lung cancer stigma among the general public and lung cancer survivors (self-blame), as well as clinicians across many disciplines. However, studies have not explored lung cancer stigma in health-care trainees. These data seek to address that gap and inform efforts to prevent the emergence or mitigate the presence of lung cancer stigma among future clinicians.

METHODS

Using clinical vignettes and a 2x2 factorial design, this investigation evaluated the impact of a history of smoking (yes vs no) and cancer diagnosis (lung vs colorectal) on perceptions of the described patient among 2 groups of preclinical health-care trainees (medical = 94 and nursing = 138). A charitable giving paradigm also asked participants to donate provided funds to 1 of 2 cancer advocacy organizations: one serving the lung cancer community and one serving the colorectal cancer community.

RESULTS

In study 1, results revealed a consistent pattern of statistically significant and medium to large effect size differences regarding stigmatized perceptions (eg, higher stigmatizing behavior, increased pity, greater anger, and less helping) for individuals with a history of smoking but no reliable differences regarding cancer diagnosis. Analysis of data from nursing trainees in study 2 showed a similar pattern of statistically significant and medium to large effects pertaining to stigma behavior and perceptions of individuals who had a history of smoking depicted in the vignettes. The charitable giving paradigm did not identify any reliable difference between the groups in either study.

CONCLUSIONS

Findings revealed a consistent pattern of health-care trainee perceptions that varied by smoking status but much less evidence that the cancer diagnosis contributed to different perceptions. This suggests that efforts to integrate consideration of stigma and biases in health-care training needs to adopt an approach that seeks to mitigate or eliminate stigmatizing perceptions and behaviors toward individuals with a history of smoking.

Young adults' stigmatizing perceptions about individuals with skin cancer: the influence of potential cancer cause, cancer metaphors, and gender

Objective: This study examined the influence of three potential predictors of stigmatising cancer perceptions: the controllability of the cancer cause, metaphors used to describe the cancer experience, and the target's gender.Method: 306 undergraduates (Mage = 20) were recruited via subject pool, balancing males and females. Participants read a fictitious post by a patient/blogger with skin cancer that described different potential causes for their cancer varying with respect to its controllability, used varying types of commonly invoked cancer metaphors, and indicated their gender with names.Main outcome measures: Potential stigmatisation of the blogger in the form of negative affective responses, perceptions of flawed character, desired social distance and expectations for post-traumatic growth were assessed using mixed methods. The perceived age of the blogger and expectations for their survival were also explored.Results: More blame, less sympathy, and less favourable perceptions of character were ascribed to the hypothetical blogger when their cancer was described as due to their lifestyle rather than genetics and thus potentially construed as more controllable. Females using a war metaphor resulted in more positive responses compared to a female using no metaphorical language.Conclusion: Stigmatisation of individuals with skin cancer may depend on the potential cause of cancer, and to some extent, metaphors and gender.

Multilevel Opportunities to Address Lung Cancer Stigma across the Cancer Control Continuum

The public health imperative to reduce the burden of lung cancer has seen unprecedented progress in recent years. Fully realizing the advances in lung cancer treatment and control requires attention to potential barriers in their momentum and implementation. In this analysis, we present and evaluate the argument that stigma is a highly significant barrier to fulfilling the clinical promise of advanced care and reduced lung cancer burden. This evaluation of the stigma of lung cancer is based on a multilevel perspective that incorporates the individual, persons in the individual's immediate environment, the health care system, and the larger societal structure that shapes perceptions and decisions. We also consider current interventions and interventional needs within and across aspects of the lung cancer continuum, including prevention, screening, diagnosis, treatment, and survivorship. Current evidence suggests that stigma detrimentally affects psychosocial, communication, and behavioral outcomes over the entire lung cancer control continuum and across multiple levels. Interventional efforts to alleviate stigma in the context of lung cancer show promise, yet more work is needed to evaluate their impact. Understanding and addressing the multilevel role of stigma is a crucial area for future study to realize the full benefits offered by lung cancer prevention, control, and treatment. Coordinated, interdisciplinary, and well-conceptualized efforts have the potential to reduce the barrier of stigma in the context of lung cancer and facilitate demonstrable improvements in clinical care and quality of life.

Stigma-related experiences in non-communicable respiratory diseases: A systematic review

The stigma of non-communicable respiratory diseases (NCRDs), whether perceived or otherwise, can be an important element of a patient’s experience of his/her illness and a contributing factor to poor psychosocial, treatment and clinical outcomes. This systematic review examines the evidence regarding the associations between stigma-related experiences and patient outcomes, comparing findings across a range of common NCRDs. Electronic databases and manual searches were conducted to identify original quantitative research published to December 2015. Articles focussing on adult patient samples diagnosed with asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, lung cancer or mesothelioma, and included a measurement of stigma-related experience (i.e. perceived stigma, shame, blame or guilt), were eligible for inclusion. Included articles were described for study characteristics, outcome scores, correlates between stigma-related experiences and patient outcomes and methodological rigor. Twenty-five articles were eligible for this review, with most (n = 20) related to lung cancer. No articles for cystic fibrosis were identified. Twenty unique scales were used, with low to moderate stigma-related experiences reported overall. The stigma-related experiences significantly correlated with all six patient-related domains explored (psychosocial, quality of life, behavioral, physical, treatment and work), which were investigated more widely in COPD and lung cancer samples. No studies adequately met all criteria for methodological rigor. The inter-connectedness of stigma-related experiences to other aspects of patient experiences highlight that an integrated approach is needed to address this important issue. Future studies should adopt more rigorous methodology, including streamlining measures, to provide robust evidence.

Association between patient-provider communication and lung cancer stigma

PURPOSE

The majority (95 %) of lung cancer patients report stigma, with 48 % of lung cancer patients specifically reporting feeling stigmatized by their medical providers. Typically associated with the causal link to smoking and the historically poor prognosis, lung cancer stigma can be seen as a risk factor for poor psychosocial and medical outcomes in the context of lung cancer diagnosis and treatment. Thus, modifiable targets for lung cancer stigma-reducing interventions are needed. The present study sought to test the hypothesis that good patient-provider communication is associated with lower levels of lung cancer stigma.

METHODS

Lung cancer patients (n = 231) across varying stages of disease participated in a cross-sectional, multisite study designed to understand lung cancer stigma. Patients completed several survey measures, including demographic and clinical characteristics, a measure of patient-provider communication (Consumer Assessment of Healthcare Providers and Systems Program or CAHPS), and a measure of lung cancer stigma (Cataldo Lung Cancer Stigma Scale).

RESULTS

As hypothesized, results indicated that good patient-provider communication was associated with lower levels of lung cancer stigma (r = -0.18, p < 0.05). These results remained significant, even when controlling for relevant demographic and clinical characteristics (Stan. β = -0.15, p < 0.05).

CONCLUSIONS

Results indicate that good patient-provider communication is associated with lower levels of lung cancer stigma, suggesting that improving patient-provider communication may be a good intervention target for reducing lung cancer stigma.

Does lung cancer attract greater stigma than other cancer types?

OBJECTIVES

Cancer stigma can have widespread effects, influencing the behaviour and wellbeing of patients as well as the community and even research funding. Patients with lung cancer report feeling particularly stigmatised because of the association with a behaviour (smoking) that is perceived to be personally controllable. However, there are other dimensions of cancer stigma, that might be more severe for other cancers. The present study therefore examined differences in attitudes towards lung cancer and four other cancer types, using a multidimensional measure of cancer stigma, to extend findings beyond personal responsibility attributions.

MATERIALS AND METHODS

Participants were a non-patient sample (n=1205) who were randomised to complete a survey online relating to one of five cancer types (lung, colorectal, skin, breast and cervical). Stigma was assessed using the Cancer Stigma Scale (CASS).

RESULTS

There were significant differences across the five cancer types on all CASS subscales: awkwardness (F(4, 1009)=5.16, p<0.001), severity (F(4, 984)=26.24, p<0.001), avoidance (F(4, 1008)=5.38, p<0.001), policy opposition (F(4, 1009)=8.38, p<0.001), personal responsibility (F(4, 995)=31.67, p<0.001) and financial discrimination (F(4, 957)=9.45, p<0.001). Lung cancer attracted higher stigma scores than breast and cervical cancer on all subscales. Lung cancer was similar to skin cancer on personal responsibility, avoidance, and policy opposition, but attracted higher stigma in the domains of awkwardness, severity and financial discrimination. Lung cancer was similar to colorectal cancer for awkwardness, but significantly higher on all other subscales.

CONCLUSION

Lung cancer stigma extends beyond personal responsibility attributions to other dimensions, particularly perceived severity of the disease and tolerance of financial discrimination against patients with the disease. Future work is needed to develop and evaluate interventions designed to limit cancer stigma for patients, health professionals and the community. Health policies should acknowledge the existence of lung cancer stigma and make a commitment to minimising this.

The role of posttraumatic growth and timing of quitting smoking as moderators of the relationship between stigma and psychological distress among lung cancer survivors who are former smokers

OBJECTIVE

Patients diagnosed with lung cancer report high levels of stigma and psychological distress. This study examined posttraumatic growth among lung cancer survivors as a potential buffer against this relationship between stigma and psychological distress and examined how these relationships differed by the timing of quitting smoking (pre versus post-diagnosis).

METHODS

Stages IA and IB non-small-cell lung cancer survivors (N = 141) who were former smokers, 1-6 years post-treatment, and had no evidence of disease completed standardized questionnaires assessing stigma, posttraumatic growth, timing of quitting smoking history, and psychological distress.

RESULTS

Hierarchical linear regression and simple slope analyses indicated that among those who quit smoking prior to diagnosis (pre-diagnosis quitters), stigma had a positive association with psychological distress at high levels of posttraumatic growth (p = 0.003) and had a positive (but non-significant) association with psychological distress among those with low levels of posttraumatic growth (p = 0.167). Among those who quit smoking after diagnosis (post-diagnosis quitters), stigma had a positive association with psychological distress among those with low levels of posttraumatic growth (p = 0.004) but had no relationship among those with high levels of posttraumatic growth (p = 0.880).

CONCLUSIONS

Findings indicate that posttraumatic growth buffers against the negative effects of stigma on psychological distress but only among post-diagnosis quitters. Future interventions could focus on fostering posttraumatic growth as a way to decrease the negative effects of stigma.

Stigma among patients with lung cancer: a patient-reported measurement model

BACKGROUND

Although stigma may have negative psychosocial and behavioral outcomes for patients with lung cancer, its measurement has been limited. A conceptual model of lung cancer stigma and a patient-reported outcome measure are needed to mitigate these sequelae. This study identified key stigma-related themes to provide a blueprint for item development through a thematic analysis of semi-structured interviews and focus groups with lung cancer patients.

METHODS

Participants were recruited from two outpatient oncology clinics and included (i) 42 lung cancer patients who participated in individual interviews and (ii) 5 focus groups (inclusive of 23 new lung cancer patients). Never smokers, long-term quitters, recent quitters, and current smokers participated. Individual interviews facilitated theme development and a conceptual model of lung cancer stigma, whereas subsequent focus groups provided feedback on the conceptual model. Qualitative data analyses included iterative coding and validation with existing theory.

RESULTS

Two main thematic elements emerged from interviews with lung cancer patients: perceived (felt) stigma and internalized (self) stigma. Discussions of perceived stigma were pervasive, whereas those of internalized stigma were more commonly endorsed among current and recently quit smokers. Participants also discussed maladaptive (e.g., decreased disclosure) and adaptive (e.g., increased advocacy) stigma-related consequences.

CONCLUSIONS

Results indicate widespread acknowledgment of perceived stigma among lung cancer patients but varying degrees of internalized stigma and associated consequences. Next steps for patient-reported outcome measure development are item consolidation, item development, expert input, and cognitive interviews before field testing and psychometric analysis. Future work should address stigma-related consequences and interventions for reducing lung cancer stigma.
