Supportive Care for Adults with Advanced Cancer and their Family Caregivers
Dr. Catherine Mosher's field of research, Pyscho-Oncology, is the study of the behavioral, psychological, and social aspects of cancer. She is interested in the experiences of both patients and their family caregivers. We know that patients often suffer from a range of debilitating symptoms such as depression, anxiety, pain and fatigue. And family caregivers are often just as distressed, if not more distressed, than the patients themselves.
Dr. Mosher's research aims to address both patients' and family caregivers' concerns by developing and testing new counseling approaches. The approaches are delivered over the telephone and online to have the broadest reach to patients and caregivers throughout the state of Indiana.
Dr. Mosher's goal is to implement and disseminate these counseling interventions into clinical practice for improved outcomes for patients with advanced cancer and their family caregivers is another excellent example of how IUPUI's faculty members are TRANSLATING their RESEARCH INTO PRACTICE.

Item Health-Related Quality of Life: A Comparative Analysis of Caregivers of People With Dementia, Cancer, COPD/Emphysema, and Diabetes and Noncaregivers, 2015–2018 BRFSS(Oxford, 2021-11) Secinti, Ekin; Lewson, Ashley B.; Wu, Wei; Kent, Erin E.; Mosher, Catherine E.; Psychology, School of ScienceBackground Many informal caregivers experience significant caregiving burden and report worsening health-related quality of life (HRQoL). Caregiver HRQoL may vary by disease context, but this has rarely been studied. Purpose Informed by the Model of Carer Stress and Burden, we compared HRQoL outcomes of prevalent groups of caregivers of people with chronic illness (i.e., dementia, cancer, chronic obstructive pulmonary disease [COPD]/emphysema, and diabetes) and noncaregivers and examined whether caregiving intensity (e.g., duration and hours) was associated with caregiver HRQoL. Methods Using 2015–2018 Behavioral Risk Factor Surveillance System data, we identified caregivers of people with dementia (n = 4,513), cancer (n = 3,701), COPD/emphysema (n = 1,718), and diabetes (n = 2,504) and noncaregivers (n = 176,749). Regression analyses were used to compare groups. Results Caregiver groups showed small, nonsignificant differences in HRQoL outcomes. Consistent with theory, all caregiver groups reported more mentally unhealthy days than noncaregivers (RRs = 1.29–1.61, ps < .001). Caregivers of people with cancer and COPD/emphysema reported more physically unhealthy days than noncaregivers (RRs = 1.17–1.24, ps < .01), and caregivers of people with diabetes reported a similar pattern (RR = 1.24, p = .01). However, general health and days of interference of poor health did not differ between caregivers and noncaregivers. Across caregiver groups, most caregiving intensity variables were unrelated to HRQoL outcomes; only greater caregiving hours were associated with more mentally unhealthy days (RR = 1.13, p < .001). Conclusions Results suggest that HRQoL decrements associated with caregiving do not vary substantially across chronic illness contexts and are largely unrelated to the perceived intensity of the caregiving. Findings support the development and implementation of strategies to optimize caregiver health across illness contexts.Item Examining Health Behaviors of Chronic Disease Caregivers in the U.S.(Elsevier, 2022-03) Secinti, Ekin; Wu, Wei; Kent, Erin E.; Demark-Wahnefried, Wendy; Lewson, Ashley B.; Mosher, Catherine E.; Psychology, School of ScienceINTRODUCTION: Many informal caregivers experience a significant caregiving burden, which may interfere with their health behaviors. Caregiver health behaviors may vary by disease context, but this has rarely been studied. This study compares the health behaviors of prevalent groups of chronic illness caregivers (i.e., dementia, cancer, chronic obstructive pulmonary disease/emphysema, diabetes) with those of noncaregivers and examines whether caregiving intensity is associated with these behaviors. METHODS: In 2021, using pooled cross-sectional 2015-2019 Behavioral Risk Factor Surveillance System data, health behaviors (i.e., physical activity, diet, alcohol use, smoking, sleep, and influenza immunization) of caregivers of patients with dementia (n=5,525), cancer (n=4,246), chronic obstructive pulmonary disease/emphysema (n=1,959), and diabetes (n=2,853) and noncaregivers (n=203,848) were compared. Relationships between caregiving intensity (e.g., hours, type of tasks) and caregiver health behaviors were examined. Regression analyses were used to compare groups. RESULTS: Compared with noncaregivers, caregiver groups were more likely to report engaging in both risky (i.e., smoking, shorter sleep duration) and health-promoting (i.e., physical activity, vegetable consumption, abstaining from heavy drinking) behaviors, whereas nonsignificant differences were observed for influenza immunization. Longer caregiving hours and providing help with personal care were associated with poorer health behaviors (e.g., shorter sleep duration). Few differences in health behaviors were observed between caregivers of patients with dementia and other caregiver groups. CONCLUSIONS: Results suggest that caregivers are more likely to engage in both risky and health-promoting behaviors than noncaregivers. Furthermore, findings suggest that greater caregiving responsibilities are associated with certain risky health behaviors. Findings support the development and implementation of strategies to improve caregivers' health behaviors across disease contexts.Item Social correlates of distress following hematopoietic stem cell transplantation: Exploring the role of loneliness and cognitive processing(SAGE, 2012-10-01) Mosher, Catherine E.; Lepore, Stephen J.; Wu, Lisa; Austin, Jane; Valdimarsdottir, Heiddis; Rowley, Scott; Isola, Luis; Redd, William H.; Rini, ChristineThis study investigated whether loneliness and cognitive processing explain the influence of negative (social constraints) and positive (emotional support) relationship qualities on cancer survivors? distress. Participants were 195 cancer survivors who had undergone hematopoietic stem cell transplantation. Path analysis supported the hypothesis that loneliness and cognitive processing would mediate the association between social constraints and distress. Only loneliness mediated the association between emotional support and distress ? an indirect effect significant only when support came from family and friends rather than a partner. Findings suggest that addressing social constraints may enhance cancer survivors? adjustment.Item Living with Metastatic Breast Cancer: A Qualitative Analysis of Physical, Psychological, and Social Sequelae(Wiley, 2013) Mosher, Catherine E.; Johnson, Courtney; Dickler, Maura; Norton, Larry; Massie, Mary Jane; DuHamel, KatherineWomen with metastatic breast cancer face a wide range of medical, practical, and emotional challenges that impact their quality of life. Research to date, however, has not focused on the quality-of-life concerns of metastatic breast cancer patients with significant distress. The present study examined a range of concerns among distressed metastatic breast cancer patients, including physical and emotional distress, social functioning, and existential issues. Forty-four distressed women with metastatic breast cancer wrote their deepest thoughts and feelings regarding their illness. These essays were thematically analyzed for effects of the illness on quality of life. Three themes were identified in patients’ essays. First, metastatic breast cancer and its treatment may result in a number of quality-of-life concerns, including physical symptom burden, emotional distress, body image disturbance, and disrupted daily activities. Second, social constraints on disclosure of cancer-related concerns may exacerbate patients’ distress. Third, many women experience a heightened awareness of life’s brevity and search for meaning in their cancer experience. Results highlight a range of quality-of-life concerns following a metastatic breast cancer diagnosis and suggest that addressing social constraints on cancer-related disclosure and the search for meaning may improve patients’ psychological adjustment.Item Long-term Outcomes of the FRESH START Trial: Exploring the Role of Self-efficacy in Cancer Survivors’ Maintenance of Dietary Practices and Physical Activity(Wiley, 2013-04) Mosher, Catherine E.; Lipkus, Isaac; Sloane, Richard; Snyder, Denise C.; Lobach, David F.; Demark-Wahnefried, WendyBackground: This study examined whether changes in self-efficacy explain the effects of a mailed print intervention on long-term dietary practices of breast and prostate cancer survivors. The relationship between change in self-efficacy and long-term physical activity (PA) also was examined. Methods: Breast and prostate cancer survivors (N = 543) from 39 US states and two Canadian provinces participated in the FRESH START intervention trial. Participants were randomly assigned to receive a 10-month program of mailed print materials on diet and PA available in the public domain or a 10-month program of tailored materials designed to increase fruit and vegetable (F&V) intake, decrease fat intake, and/or increase PA. Changes in self-efficacy for F&V intake and fat restriction were analyzed as potential mediators of the intervention's effects on diet at 2-year follow-up. Because we previously found that change in self-efficacy for PA did not vary by group assignment, the relationship between change in self-efficacy and PA at 2-year follow-up was examined across study conditions. Results: Results suggest that change in self-efficacy for fat restriction partially explained the intervention's effect on fat intake (mean indirect effect = -0.28), and change in self-efficacy for F&V consumption partially explained the intervention's effect on daily F&V intake (mean indirect effect = .11). Change in self-efficacy for fat restriction partially accounted for the intervention's impact on overall diet quality among men only (mean indirect effect = 0.60). Finally, change in self-efficacy for PA predicted PA at 2-year follow-up. Conclusions: Findings suggest that self-efficacy may influence long-term maintenance of healthy lifestyle practices among cancer survivors.Item Distressed family caregivers of lung cancer patients: an examination of psychosocial and practical challenges(Springer, 2013-02) Mosher, Catherine E.; Jaynes, Heather A.; Hanna, Nasser; Ostroff, Jamie S.Purpose: Lung cancer and its treatment impose many demands on family caregivers, which may increase their risk for distress. However, little research has documented aspects of the caregiving experience that are especially challenging for distressed caregivers of lung cancer patients. This study aimed to explore caregivers' key challenges in coping with their family member's lung cancer. Methods: Single, semi-structured qualitative interviews were conducted with 21 distressed family caregivers of lung cancer patients. Results: Caregivers described three key challenges in coping with their family member's lung cancer. The most common challenge, identified by 38 % of caregivers, was a profound sense of uncertainty regarding the future as they attempted to understand the patient's prognosis and potential for functional decline. Another key challenge, identified by 33 % of caregivers, involved time-consuming efforts to manage the patient's emotional reactions to the illness. Other caregivers (14 %) characterized practical tasks, such as coordinating the patient's medical care, as their greatest challenge. Conclusions: Results suggest that clinical efforts are needed to assist distressed caregivers in providing practical and emotional support to the patient and attending to their own emotional needs.Item Support Service Use and Interest in Support Services among Distressed Family Caregivers of Lung Cancer Patients(Wiley, 2013-07) Mosher, Catherine E.; Champion, Victoria L.; Hanna, Nasser; Jalal, Shadia I.; Fakiris, Achilles J.; Birdas, Thomas J.; Okereke, Ikenna C.; Kesler, Kenneth A.; Einhorn, Lawrence H.; Given, Barbara A.; Monahan, Patrick O.; Ostroff, Jamie S.Objective: This study examined support service use and interest in support services among distressed family caregivers of patients recently entering comprehensive cancer care facilities. Methods: Primary family caregivers of lung cancer patients (N=83) were recruited from three medical centers within 12 weeks of the patient's new visit to the oncology clinic. All family caregivers were screened for psychological distress, and those reporting significant anxiety or depressive symptoms were eligible for this study. Caregivers completed a baseline assessment of support service use (i.e., use of mental health services and complementary and alternative medicine [CAM]) and interest in support services. Support service use was also assessed 3 months later. Results: Although all caregivers reported clinically meaningful distress, only 26% used mental health and 39% used CAM services during the 3-month study period. Patients' receipt of chemotherapy was positively associated with caregivers' mental health service use, whereas greater education and receiving assistance with caregiving tasks were associated with CAM use. Forty percent of caregivers who did not use CAM at baseline were interested in CAM. In addition, 29% of caregivers who did not receive mental health services at baseline were interested in professional psychosocial support, and 29% of caregivers who did not receive staff assistance with practical needs at baseline were interested in this service. Conclusions: Findings suggest that distressed family caregivers of lung cancer patients underuse mental health services and that a sizable minority are interested in professional help with psychosocial and practical needs.Item Support Service Use and Interest in Support Services among Lung Cancer Patients(Wiley, 2013-10) Mosher, Catherine E.; Champion, Victoria L.; Hanna, Nasser; Jalal, Shadia I.; Fakiris, Achilles J.; Birdas, Thomas J.; Okereke, Ikenna C.; Kesler, Kenneth A.; Einhorn, Lawrence H.; Given, Barbara A.; Monahan, Patrick O.; Ostroff, Jamie S.Objective: This study examined support service use and interest in support services among distressed family caregivers of patients recently entering comprehensive cancer care facilities.

In addition, research has not focused on caregivers with greater need for support services. This study examined various economic and social changes among distressed family caregivers of lung cancer patients during the initial months of cancer care in the USA. Methods: Lung cancer patients' primary family caregivers with significant anxiety or depressive symptoms were recruited from three medical centers within 12 weeks of the patient's new oncology visit. Caregivers (N = 83) reported demographic and medical information and caregiving burden at baseline. Seventy-four caregivers reported anxiety and depressive symptoms and economic and social changes 3 months later. Results: Seventy-four percent of distressed caregivers experienced one or more adverse economic or social changes since the patient's illness. Common changes included caregivers' disengagement from most social and leisure activities (56%) and, among employed caregivers (n = 49), reduced hours of work (45%). In 18% of cases, a family member quit work or made another major lifestyle change due to caregiving. Additionally, 28% of caregivers reported losing the main source of family income, and 18% reported losing most or all of the family savings. Loss of the main source of family income and disengagement from most social and leisure activities predicted greater caregiver distress. Conclusions: Findings suggest that distressed caregivers of lung cancer patients experience high rates of adverse economic and social changes that warrant clinical and research attention.Item Randomised trial of expressive writing for distressed metastatic breast cancer patients(Elsevier, 2012-01-01) Mosher, Catherine E.; DuHamel, Katherine N.; Lam, Joanne; Dickler, Maura; Li, Yuelin; Massie, Mary Jane; Norton, LarryWomen with metastatic breast cancer and significant psychological distress (N = 87) were assigned randomly to engage in four home-based sessions of expressive writing or neutral writing. Women in the expressive writing group wrote about their deepest thoughts and feelings regarding their cancer, whereas women in the neutral writing group wrote about their daily activities in a factual manner. No statistically significant group differences in existential and psychological well-being, fatigue and sleep quality were found at 8-weeks post-writing. However, the expressive writing group reported significantly greater use of mental health services during the study than the neutral writing group (55% vs. 26%, respectively; p < 0.05). Findings suggest that expressive writing may improve the uptake of mental health services among distressed cancer patients, but is not broadly effective as a psychotherapeutic intervention.
