Item 4024 Theory and Scale Development for Cancer-Related Self-Efficacy in Partners of Breast Cancer Survivors(2020) Cohee, Andrea; Draucker, Claire; Monahan, Patrick; Champion, VictoriaOBJECTIVES/GOALS: Specific aims are to: (Qualitative aim) Develop a new measure of cancer-related self-efficacy in partners (BCSES-P) and obtain feedback on the items (Quantitative) Evaluate the psychometric properties of the BCSES-P including: dimensionality, factor analysis, and construct validity assessing the relationships posited METHODS/STUDY POPULATION: 2- Phase Approach: 1) Item development and 1) Item testing Phase 1 Stage 1: Literature review to identify additional covariates Stage 2: Focus groups and individual interviews to determine partners’ needs Sample size: 20 partners (18 years of age or older, identifying as being in a committed relationship with a BCS) Design: cross-sectional, qualitative interviews Stage 3: Develop candidate items Stage 4: Cognitive interviews Stage 5: Finalize items with research team Phase 2 Preliminary psychometric testing Dimensionality Internal consistency reliability Construct validity Sample size: 150 partners Design: cross-sectional, online survey RESULTS/ANTICIPATED RESULTS: The BCSES-P will be unidimensional as assessed by exploratory factor analysis. The BCSES-P will demonstrate an internal consistency coefficient of 0.70 or above. Construct validity of the BCSES-P will be demonstrated by support of the following theoretical relationships: Cancer-related self-efficacy will be positively related to marital satisfaction and sexual functioning (social well- being) and the distal outcome, overall QoL. Cancer-related self-efficacy will be negatively related to fatigue (physical well-being), fear of recurrence, depression, and anxiety (psychological well-being). DISCUSSION/SIGNIFICANCE OF IMPACT: Findings will guide intervention development to improve partners’ quality of life The BCSES-P will be the first scale to measure partners’ cancer-related self-efficacy. This study will highlight a holistic approach to studying the long-term effects of breast cancer on partners.Item The association between maternal human papillomavirus (HPV) experiences and HPV vaccination of their children(Taylor & Francis, 2021-04-03) Biederman, Erika; Donahue, Kelly; Sturm, Lynne; Champion, Victoria; Zimet, Gregory; School of NursingHPV vaccination prevents most HPV-related cancers yet vaccination rates remain low. In this cross-sectional study, we examined the association between maternal HPV experiences and HPV vaccination uptake among children and whether this association may be explained by perceived benefits of vaccination. We used logistic regression models to estimate the effect of (1) maternal history of abnormal Pap smear, (2), family/friend history of cervical cancer, and (3) maternal history of cervical cancer on HPV vaccination uptake among children. Separate mediation analyses were conducted to determine if perceived benefits mediated the relationship between each maternal HPV experience and HPV vaccination uptake. History of abnormal Pap smear (OR = 1.50, 95% CI = 1.15, 1.97), family history of cervical cancer (OR = 1.72, CI = 1.26, 2.35), and personal history of cervical cancer (OR = 3.00, CI = 1.82, 4.95) predicted HPV vaccination of children. Perceived benefits mediated the relationship between history of abnormal Pap smear (indirect effect =.146, SE =.069, 95% CI =.014, .289), family history of cervical cancer (indirect effect =.228, SE =.079, CI =.080, .387), and personal history of cervical cancer (indirect effect =.298, SE =.116, CI =.082, .533) on HPV vaccination. Our results suggest that personal experiences with HPV-related disease may influence maternal HPV vaccine decision-making.Item Bridging the Gap in Tobacco Cessation Services: Utilizing Community Pharmacists to Facilitate Transitions of Care in the USA(Springer, 2022) Newlon, Jenny; Ellis Hilts, Katy; Champion, Victoria; Suchanek Hudmon, Karen; School of NursingInterprofessional strategies for promoting tobacco cessation lead to enhanced quit rates among patients; however, current approaches might not effectively support patients with their quit attempts after they are discharged from the hospital. This paper explores opportunities for interprofessional collaboration between health system-based providers and community pharmacists, as one proposed approach to bridging tobacco cessation services during transitions of care. Suggested strategies include (1) increasing other healthcare professionals' awareness of legislative advances that permit pharmacists to prescribe cessation medications in some states, and (2) encouraging bi-directional communication between health system-based and community-based providers, especially via integrated electronic health records. Community pharmacists can offer a convenient solution to obtain the post-discharge medication and counseling support that patients need to increase their chances of quitting for good. Additional steps are discussed to improve broadscale capacity of this service being provided in community pharmacies.Item Champion’s Health Belief Model Scale Validity Evidence for Brazil(UNIFESP, 2020) Moreira, Camila Brasil; Carvalho Fernandes, Ana Fátima; Champion, Victoria; Dahinten, Virginia Susan; da Silva Carvalho Vila, Vanessa; Howard, Amanda Fuchsia; Oliveira Batista Oriá, Mônica; Schirmer, Janine; School of NursingObjective Performing translation and cross-cultural adaptation of the Champion’s Health Belief Model Scale (CHBMS) for use in Brazil for mammographic screening, and verify the validity evidence of the Brazilian version of this scale. Methods Methodological study, conducted with 206 women attending a Basic Health Unit, in the city of Fortaleza, state of Ceará, Brazil, from August 2015 to December 2017. The scale went through a process of translation and cross-cultural adaptation, including face and content validation. Afterwards, validity evidence was verified (1.Vality based on internal structure, assessed by exploratory analysis, with varimax orthogonal rotation and retention of factors by parallel analyzes; 2. Reliability from Cronbach’s alpha homogeneity and test-retest stability). Results In face and content validation, the tool showed good acceptance among the judges and the target audience. The final exploratory factor analysis model resulted in a seven-item scale, divided into three domains, with an explained variance of 71.4%, with Cronbach’s alpha ranging from 0.50 to 0.88. For scale reliability, Pearson r and Spearman ρ showed high reliability (0.997 and 0.986). Conclusion The Brazilian version of Champion’s Health Belief Model Scale provides good evidence of validity based on internal structure and is reliable. It may be used in Brazil to assess mammography compliance monitoring.Item Cognitive Dysfunction in Older Breast Cancer Survivors(2020-09) Crouch, Adele Deborah Lenae; Von Ah, Diane; Champion, Victoria; Pressler, Susan J.; Unverzagt, Frederick; Huber, LesaUp to 75% of the more than 3.5 million breast cancer survivors (BCS) living in the United States report cognitive dysfunction. However, little is known about cognitive dysfunction among older BCS, who may be at greater risk. Therefore, the purpose of this dissertation was to characterize cognitive dysfunction in older BCS. Specific aims included: (1) synthesize the literature regarding cognitive dysfunction in older BCS; and (2) examine the relationships between a) objective cognitive function (immediate memory, delayed memory, attention, executive function-working memory, verbal fluency) and subjective cognitive function (attention); b) demographic factors, medical factors, treatment factors, and cancer-related symptoms (depressive symptoms, anxiety, fatigue, sleep disturbance) and cognitive function; and c) comorbidity and cognitive function and physical functioning, and quality of life (QoL) in older BCS. In an integrative review, to address aim 1, 12 studies were identified. Up to 41% of older BCS showed objective cognitive dysfunction on neuropsychological assessment, up to 64% reported subjective cognitive dysfunction concerns pre-treatment, and 50% incurred cognitive decline from pre- to post-treatment. Cognitive dysfunction was associated with older age, multiple comorbidities, chemotherapy, sleep disturbance, neuropsychological symptom cluster, frailty, and poorer QoL. To address aim 2, data were leveraged from a large, nationwide, QoL in younger versus older BCS study (PI: Champion), which included 335 older BCS who were ≥60 years of age, had breast cancer (stage I-IIIa), received chemotherapy, and were 3-8 years post-diagnosis without recurrence. Findings included up to 19% of older BCS had mild-moderate objective cognitive dysfunction on at least one neuropsychological assessment, with 26% reporting poor-moderate subjective attention function. BCS, who were older, had less education and more depressive symptoms had greater cognitive dysfunction. Objective attention and executive function-working memory significantly and positively correlated with subjective attention. In turn, subjective cognitive dysfunction and increased number of comorbidities were related to poorer physical functioning. Subjective cognitive dysfunction was also related to poorer QoL. The findings from this study highlights the prevalence and complexity of cognitive dysfunction in older BCS. Further research is needed to better understand the intersection of aging, cancer, comorbidities and cognitive dysfunction and the negative implications in older BCS.Item Cognitive Dysfunction in Older Breast Cancer Survivors: An Integrative Review(Wolters Kluwer, 2022) Crouch, Adele; Champion, Victoria; Von Ah, Diane; School of NursingBackground: Approximately 60% of the more than 3.8 million breast cancer survivors (BCSs) living in the United States are 60 years or older. Breast cancer survivors experience many symptoms including cognitive dysfunction; however, little is known regarding how age affects these symptoms. Objective: This integrative review was conducted to synthesize the literature on cognitive dysfunction in older BCSs. The purpose was to (1) describe the prevalence of objective and subjective cognitive dysfunctions and (2) examine factors associated with cognitive dysfunction in older BCSs. Methods: Whittemore and Knafl's integrative review methodology was used to examine cognitive dysfunction in BCSs 60 years or older. Results: Twelve quantitative studies were included. Up to 41% of older BCSs experienced cognitive dysfunction on neuropsychological examination, and up to 64% reported cognitive dysfunction on subjective measures pretreatment. Approximately half of older BCSs experienced cognitive decline from pretreatment to posttreatment regardless of cognitive measure. The domains most impacted were memory, executive functioning, and processing speed. Objective and subjective cognitive dysfunctions were associated with age, comorbidities, chemotherapy receipt, sleep, neuropsychological symptom cluster, frailty, and quality of life. Conclusions: Cognitive dysfunction among older BCSs was common both prior to and following treatment. Cognitive dysfunction was associated with multiple factors that are compounded in the aging population and could be detrimental to quality of life and independent living. Implications to practice: Early assessment and intervention by healthcare providers, including nurses, for cognitive dysfunction in older BCSs are essential. Future research should focus on evidence-based interventions for cognitive dysfunction incorporating the unique needs of older BCSs.Item A cohort study of quality of life in partners of young breast cancer survivors compared to partners of healthy controls(Springer, 2020-03-06) Cohee, Andrea A.; Storey, Susan; Winger, Joseph; Cella, David; Stump, Timothy; Monahan, Patrick; Champion, VictoriaBackground Partners of young breast cancer survivors (BCS) are at increased risk for deficits in quality of life (QoL). To intervene effectively, it is important to understand how the breast cancer experience impacts partners. The purpose of this study was to compare QoL between partners of young BCS and partners of healthy acquaintance controls. Methods Partners of young BCS (3–8 years post treatment and ≤ 45 years old at diagnosis) and partners of age-matched healthy acquaintance controls completed questionnaires on overall, physical (physical function, sexual difficulty), social (personal resources, sexual enjoyment, marital satisfaction, partner social support, social constraints, parenting satisfaction), psychological (depressive symptoms), and spiritual (behaviors, beliefs, and activities) QoL. Analyses included descriptive statistics and one-way ANOVA to compare partner groups on all study variables. Results Although partners of young BCS (n = 227) reported fewer social constraints (p < .001), they reported lower overall QoL (p < .001), fewer personal resources (p < .001), more sexual difficulty (p = .019), less sexual enjoyment (p = .002), less marital satisfaction (p = .019), more depressive symptoms (p = .024), and fewer spiritual behaviors (p < .001), beliefs (p = .001) and activities (p = .003) compared to partners of healthy acquaintance controls (n = 170). Additional analysis showed that perceptions that the relationship changed for the better since cancer, social constraints, partner social support, and depression predicted marital satisfaction among partners of young BCS. Conclusions Partners of young BCS are at risk for poorer overall, physical, social, psychological, and spiritual QoL compared to partners of healthy women. Interventions targeting QoL domains may enable partners to effectively support their partner and improve their QoL.Item A conjoint analysis study on self-sampling for human papillomavirus (HPV) testing characteristics among black women in Indiana(BMC, 2020) Biederman, Erika; Champion, Victoria; Zimet, Gregory; Pediatrics, School of MedicineBackground Self-sampling for HPV testing may be a method to increase overall cervical cancer screening rates among Black women, who are underscreened for cervical cancer in parts of the US. The purpose of this study was to assess preferred characteristics for delivery of HPV self-sampling kits, return of HPV self-sampling kits, and communication of HPV test results and explore sociodemographic factors (income, education, and marital status) associated with acceptability of self-sampling for HPV testing. Methods Survey data were gathered at an Indiana minority health fair. Participants evaluated 9 scenarios that varied along 3 dimensions: HPV self-sampling kit delivery (mail, pharmacy pick-up, or clinic pick-up), HPV self-sampling kit return (mail, pharmacy drop-off, or clinic drop-off), and HPV test results (mail, phone call, or text message). The 9 scenarios were produced from a fractional factorial design and rated on a 0 to 100 scale. Ratings-based conjoint analysis (RBCA) determined how each dimension influenced ratings. A measure for acceptability of self-sampling was obtained from the ratings of all 9 scenarios. The acceptability measure was regressed on sociodemographics. Results The 98 participants ranged in age from 21 to 65 (M = 45). Across the 9 scenarios, overall acceptability to self-sample had a mean of 60.9 (SD = 31.3). RBCA indicated that HPV self-sampling kit return had the most influence on ratings, followed by HPV self-sampling kit delivery, and finally, HPV test result communication. Thirty-six percent of participants rated all self-sampling scenarios the same. Sociodemographic characteristics were not associated with acceptability of self-sampling. Conclusions Self-sampling for HPV testing was found to be generally acceptable to Black women in this pilot survey study. This information could be used by researchers developing self-sampling interventions and the implementation of self-sampling among providers.Item A conjoint analysis study on self-sampling for human papillomavirus (HPV) testing characteristics among black women in Indiana(BioMed Central, 2020-03-19) Biederman, Erika; Champion, Victoria; Zimet, Gregory; School of NursingSelf-sampling for HPV testing may be a method to increase overall cervical cancer screening rates among Black women, who are underscreened for cervical cancer in parts of the US. The purpose of this study was to assess preferred characteristics for delivery of HPV self-sampling kits, return of HPV self-sampling kits, and communication of HPV test results and explore sociodemographic factors (income, education, and marital status) associated with acceptability of self-sampling for HPV testing.Item Development and Testing of the Colonoscopy Embarrassment Scale(2010-01-26T20:06:42Z) Mitchell, Kimberly Ann; Rawl, Susan M.; Champion, Victoria; Jeffries, Pamela R.; Welch, Janet L.Colorectal cancer (CRC), the third leading cause of cancer-related death in the U.S., could largely be prevented if more people had polyps removed via colonoscopies. Embarrassment has been identified as one important barrier to colonoscopy, but little is known about embarrassment in this context. Further, there is no instrument available to measure this construct. Therefore, the purpose of this study was to develop a reliable and valid instrument to measure colonoscopy-related embarrassment. The study aims were to: 1) estimate reliability and validity of a new instrument, the Colonoscopy Embarrassment Scale (CES); 2) examine relationships among demographic/personal characteristics, health beliefs, and CES scores; 3) examine relationships among demographic/personal characteristics, physician recommendation, health beliefs, and colonoscopy compliance; and 4) evaluate participants’ perceptions of aspects of having a colonoscopy that are most embarrassing and their suggestions for reducing embarrassment. The Health Belief Model and Transtheoretical Model of Change provided theoretical support for this study. Participants were HMO members aged 50-65 years (n=234). Using a cross-sectional, descriptive research design, data were collected using a mailed survey. The response rate was 56%. Data were analyzed using independent samples t-tests, correlations, Chi Square, and regression. Results showed that the six-item CES had internal consistency (Cronbach’s alpha of .89) and construct validity. Lower income, higher BMI, lower CRC knowledge, higher barriers, and lower self-efficacy were related to higher CES scores (or more embarrassment). Higher CRC knowledge, lower barriers, higher self-efficacy, and a physician recommendation for the test were related to higher compliance with colonoscopy. Lower barriers, higher self-efficacy, and a physician recommendation were predictive of compliance with colonoscopy. In conclusion, embarrassment is a significant barrier to colonoscopy, yet there are steps that can be taken to reduce embarrassment such as increasing privacy and limiting bodily exposure. The CES is a tool that can be used to measure colonoscopy-related embarrassment and the results could be used in developing further interventions to reduce embarrassment, leading to increased colonoscopies and lower mortality.
