A two-dimensional model of disrupted body integrity: initial evaluation in head and neck cancer.

PURPOSE: This cross-sectional study presents an initial psychometric evaluation of a two-dimensional (perceptual and evaluative) conceptualization and measure of disrupted body integrity (DBI)-illness-related disruption of the sense of the body as an integrated, smoothly functioning whole. METHODS: Male and female head and neck cancer (HNC) outpatients (N = 98) completed a questionnaire package prior to outpatient visits. MAIN OUTCOME MEASURES: The Disrupted Body Integrity Scale (DBIS) was developed to measure the perceptual and evaluative facets of DBI. Self-report measures of disfigurement, stigma, depressive symptoms, and negative affect were also completed. RESULTS: Almost all DBIS subscales demonstrated good internal consistency. Results largely supported the DBIS's construct validity. The majority of subscales correlated within the predicted range of r's = .40-.70. Almost all DBIS constructs were positively linked with either depressive symptoms or disfigurement. None correlated with positive affect, and only two subscales, abnormal sensations (perceptual) and physical vulnerability (evaluative), correlated with negative affect. DBIS constructs showed little relation with stigma, once disfigurement effects were controlled for. CONCLUSIONS: Findings offer preliminary evidence for the DBIS and the relevance of DBI in HNC. Further evaluation of DBI in disease adaptation and the DBIS's factor structure is warranted.

Do stigma and its psychosocial impact differ between Asian-born Chinese immigrants and Western-born Caucasians with head and neck cancer?

Stigma appears to influence emotional distress and well-being in cancer survivors, but cross-cultural differences have been ignored. Previous studies suggest that stigma may be especially relevant for survivors of Asian origin. However, their study designs (e.g. focused on female cancers, qualitative designs, and an absence of comparison groups) limit the strength of this conclusion. We hypothesized that (1) Asian-born Chinese immigrants (AI) would report more perceived cancer-related stigma than Western-born Caucasians (WBC); and (2) the impact of stigma on emotional distress and well-being would be greater in AI as compared to WBC. Head and neck cancer survivors (n = 118 AI and n = 404 WBC) completed measures of well-being, emotional distress, and a three-item indicator of stigma in structured interviews. The majority of respondents (59%) reported one or more indicators of stigma. Stigma correlated significantly with emotional distress (r = .13, p = .004) and well-being (r = -.09, p = .032). Contrary to our hypotheses, WBCs and AIs did not differ in reported stigma nor did we detect differences in its psychosocial impact. Stigma exerts a deleterious psychosocial impact on head and neck cancer survivors. It did not differ significantly between AI and WBC survivors.

Distancing, self-esteem, and subjective well-being in head and neck cancer.

BACKGROUND: Distancing (i.e. construing oneself as dissimilar to a negatively-stereotyped group) preserves self-esteem and may benefit other domains of subjective well-being. Head and neck cancer (HNC) is stigmatized because major risk factors include avoidable lifestyle variables (smoking, alcohol consumption, and human papilloma virus). Because the benefits of coping efforts, such as distancing, are most evident when people are under stress, we hypothesize that the psychosocial benefits of distancing will be most pronounced when cancer and its treatment interfere substantially with participation in valued activities and interests (i.e. high illness intrusiveness). OBJECTIVE: To test whether distancing preserves self-esteem and other domains of subjective well-being (SWB) in HNC, especially when illness intrusiveness is high. METHODS: Five hundred and twenty-two HNC outpatients completed a semantic-differential measure of perceived similarity to the 'cancer patient' and measures of illness intrusiveness, self-esteem, depressive symptoms, and psychological well-being in structured interviews. Evaluations of the 'cancer patient' reflected cancer stereotypes. RESULTS: A statistically significant interaction supported the central hypothesis: When people held negative stereotypes, those who construed themselves as similar to the 'cancer patient' reported lower self-esteem than those who construed themselves as dissimilar. Distancing did not benefit other SWB variables. Some results were counter-intuitive: e.g. Emotional distress increased with increasing illness intrusiveness when people did not hold negative cancer stereotypes, but when they held highly negative stereotypes, distress decreased with increasing illness intrusiveness. CONCLUSIONS: Overall, distancing preserved self-esteem in people with HNC and was associated with benefits in other SWB domains.

The effectiveness of loyalty rewards to promote the use of an Internet-based heart health program.

BACKGROUND: Internet-based health programs have been shown to be effective in reducing risk for cardiovascular disease. However, their rates of enrollment and engagement remain low. It is currently unclear whether rewards from established loyalty programs can serve as a conditioned stimulus to improve the use of a freely available Internet-based program. OBJECTIVE: The objectives of the study were to (1) examine enrollment rates and levels of engagement with the My Health eSupport program between a Conditioned Reward group and a Control group, and (2) investigate the influence of loyalty rewards and participant characteristics on levels of enrollment and program engagement. METHODS: The study sample (n=142,726) consisted of individuals who were offered enrollment in an Internet-based health intervention (My Health eSupport) after completing the Heart&Stroke Risk Assessment on the Heart and Stroke Foundation website. My Health eSupport programs provided encouragement and tips for lifestyle change. This is a free, self-guided, fully automated program that proactively delivers tailored email messages at 2-week intervals based on the participant's stage of motivational "readiness" and priority for lifestyle change. Participants in the Conditioned Reward group were offered a single exposure of 20 loyalty reward points from the Air Miles loyalty program for completing the Heart&Stroke Risk Assessment (10 reward points) and enrolling in the Internet-based program (10 reward points). Meanwhile, no rewards were given to the Control group participants. All data were collected between February 1, 2011 and February 10, 2012. RESULTS: In total, 51.38% (73,327/142,726) of individuals in the Conditioned Reward group and 48.62% (69,399/142,726) of individuals in the Control group completed the Heart&Stroke Risk Assessment. Subsequently, significantly more individuals from the Conditioned Reward group (52.96%, 38,835/73,327) enrolled in the My Health eSupport program than Controls (4.07%, 2826/69,399). Regression analyses indicated that individuals were 27.9 times (95% CI 26.4-29.4; P<.001) more likely to join the My Health eSupport program when presented with loyalty rewards controlling for gender, age, education, ethnicity, employment, and number of modifiable risk factors. However, ongoing engagement level was low in both groups and it was not influenced by loyalty rewards. Instead, individuals were more likely to engage with the My Health eSupport program if they were greater than 60 years of age (OR 12.56, 95% CI 5.66-27.8; P<.001), were female (OR 1.27, 95% CI 1.09-1.46; P=.002), or had one or more modifiable risk factors (OR 1.38, 95% CI 1.31-1.45; P<.001). CONCLUSIONS: Our findings suggest that a single exposure of loyalty rewards may be used to encourage individuals to enroll in an Internet-based preventative health program, but additional strategies are required to maintain engagement level. Future studies need to examine the schedules of loyalty reward reinforcement on the long-term engagement level of Internet-based health programs.

E-counseling as an emerging preventive strategy for hypertension.

PURPOSE OF REVIEW: Lifestyle counseling that includes exercise training, diet modification, and medication adherence is critical to hypertension management. This article summarizes the efficacy of lifestyle counseling interventions in face-to-face, telehealth, and e-counseling settings. It also discusses the therapeutic potential of e-counseling as a preventive strategy for hypertension. RECENT FINDINGS: The recent proliferation of telehealth and e-counseling programs increases the reach of preventive counseling for patients with cardiovascular disorders. Blood pressure reduction following these interventions is comparable to face-to-face interventions. However, the effectiveness of e-counseling varies depending on the design features of the core protocol. An evidence-based guideline needs to be established that identifies e-counseling components which are independently associated with blood pressure reduction. As the Internet becomes more sophisticated, e-counseling is demonstrating a therapeutic advantage in comparison with other telehealth interventions. SUMMARY: Current evidence supports further development of preventive e-counseling programs for hypertension. A pressing challenge for investigators is to specify key evidence-based components of e-counseling that are essential to the core protocol. In order to achieve this goal, it will be necessary to ensure that e-counseling programs are also clinically organized, in order to guide patients through the process of initiating and sustaining therapeutic behavior change.

Negative cancer stereotypes and disease-specific self-concept in head and neck cancer.

BACKGROUND: Life-threatening diseases, such as head and neck cancer (HNCa), can stimulate the emergence of a new disease-specific self-concept. We hypothesized that (i) negative cancer-stereotypes invoke distancing, which inhibits the adoption of a disease-specific self-concept and (ii) patient characteristics, disease and treatment factors, and cancer-related stressors moderate the phenomenon. METHODS: Head and neck cancer outpatients (N = 522) completed a semantic-differential measure of disease-specific self-concept (perceived similarity to the 'cancer patient') and other self-report measures in structured interviews. Negative cancer-stereotypes were represented by the number of semantic-differential dimensions (0-3) along which respondents evaluated the stereotypic 'cancer patient' negatively (i.e., negative valence). We tested the two-way interactions between negative valence and hypothesized moderator variables. RESULTS: We observed significant negative valence × moderator interactions for the following: (i) patient characteristics (education, employment, social networks); (ii) disease and treatment factors (cancer-symptom burden); and (iii) cancer-related stressors (uncertainty, lack of information, and existential threats). Negative cancer stereotypes were consistently associated with distancing of self from the stereotypic 'cancer patient,' but the effect varied across moderator variables. All significant moderators (except employment and social networks) were associated with increasing perceived similarity to the 'cancer patient' when respondents maintained negative stereotypes; perceived similarity decreased when people were employed or had extensive social networks. Moderator effects were less pronounced when respondents did not endorse negative cancer stereotypes. DISCUSSION: When they hold negative stereotypes, people with HNCa distance themselves from a 'cancer patient' identity to preserve self-esteem or social status, but exposure to cancer-related stressors and adaptive demands may attenuate these effects.

The burden of stress in head and neck cancer.

BACKGROUND: Head and neck cancer (HNCa) introduces numerous stressors. We developed the Cancer-Related Stressors Checklist (CRSC), which documents exposure to seven categories of common stressors and emotional distress. We surveyed HNCa survivors and examined associations among exposure to cancer-related stressors, illness intrusiveness (i.e., cancer-induced interference with lifestyles, activities, and interests), and distress. We also investigated whether reported exposure rates differ between self-administered and interviewer-administered measures. METHODS: Respondents included HNCa survivors, stratified by sex, who participated in one of two clinical studies (N1 = 162; N2 = 408) examining the psychosocial impact of illness intrusiveness. All completed the CRSC, the Center for Epidemiologic Studies Depression Scale, and the Illness Intrusiveness Ratings Scale. Study 1 respondents self-administered the instruments; an interviewer administered them in Study 2. We gathered clinical data by self-report and from medical records. RESULTS: High inter-rater reliability corroborated the 8-subscale structure of the CRSC (Krippendorff alpha = .92). Cancer-related stressor exposures differed significantly across categories (interpersonal stressors were most common). Controlling for empirically identified covariates and distress, exposure to each cancer-related stressor correlated significantly and uniquely with illness intrusiveness. All stressor categories correlated significantly with distress, but coefficients were low to moderate, substantiating incremental validity. Respondents reported fewer exposures when materials were self-administered as compared with interviewer-administered, but reported distress levels did not differ by mode of administration. CONCLUSIONS: Cancer-related stressors are common and burdensome in HNCa and, therefore, merit clinical attention. Identifying specific stressors will allow more targeted and effective interventions to alleviate and prevent distress.
