    Cognitive Dysfunction in Older Breast Cancer Survivors
    (2020-09) Crouch, Adele Deborah Lenae; Von Ah, Diane; Champion, Victoria; Pressler, Susan J.; Unverzagt, Frederick; Huber, Lesa
    Up 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.

    Factors associated with depressive symptoms in young long-term breast cancer survivors
    (Springer, 2016-08) Cohee, Andrea A.; Stump, Timothy; Adams, Rebecca N.; Johns, Shelley A.; Von Ah, Diane; Zoppi, Kathleen; Fife, Betsy; Monahan, Patrick O.; Cella, David; Champion, Victoria L.; Department of Nursing, IU School of Nursing
    Purpose Long-term breast cancer survivors frequently report distress (i.e., depressive symptoms) that impacts their quality of life. Previous studies have found that negative social interactions (“social constraints”) from partners contribute to long-term, unresolved cycling of intrusive thoughts and cognitive avoidance, resulting in psychological distress. However, these relationships have not been tested in long-term breast cancer survivors. Furthermore, the effect of partners’ depressive symptoms on the survivors’ depressive symptoms has not been tested within the context of these relationships. Therefore, the purpose of this study was to test relationships between breast cancer survivors’ depressive symptoms and (1) social constraints, cognitive avoidance, and intrusive thoughts, and (2) partners’ depressive symptoms. Methods Data were from a cross-sectional descriptive study of breast cancer survivors (N = 222) 3–8 years post-diagnosis and their partners, who completed surveys assessing demographic characteristics, social constraints, intrusive thoughts, cognitive avoidance, and depressive symptoms. Structural equation modeling confirmatory path analyses were conducted to determine significant relationships between survivors’ depressive symptoms and all other variables. Results Our model fits the data well. Breast cancer survivors’ depressive symptoms were predicted by social constraints and intrusive thoughts. The relationship between survivors’ depressive symptoms and partners’ depressive symptoms was close but not significant. Conclusions As hypothesized, depressive symptoms were predicted by social constraints and intrusive thoughts. Further research is needed to understand the possible relationship between survivors’ long-term depressive symptoms and cognitive avoidance and partners’ depressive symptoms. Our findings highlight the negative impact of social constraints from partners on psychological outcomes in long-term breast cancer survivors.

    Long-Term Fear of Recurrence in Young Breast Cancer Survivors and Partners
    (Wiley, 2017-01) Cohee, Andrea A.; Adams, Rebecca N.; Johns, Shelley A.; Von Ah, Diane; Zoppi, Kathleen; Fife, Betsy; Monahan, Patrick O.; Stump, Timothy; Cella, David; Champion, Victoria L.; Department of Nursing, IU School of Nursing
    Background Fear of a breast cancer recurrence is the most prevalent and disruptive source of distress for long-term survivors and their partners. However, few studies have focused on predictors of fear of recurrence. The aim of this study is to test the efficacy of the Social Cognitive Processing Theory (SCPT) in predicting fear of recurrence in long-term breast cancer survivors diagnosed at age 45 years or younger and their partners. Methods In a large cross-sectional study, breast cancer survivors (n = 222) 3–8 years from diagnosis and their partners completed a survey assessing demographic characteristics, fear of recurrence, social constraints, and cognitive processing (intrusive thoughts and cognitive avoidance). Mediation analyses were conducted for survivors and partners separately to determine if cognitive processing would mediate the relationship between social constraints and fear of recurrence. Results Cognitive processing mediated the relationship between social constraints and fear of recurrence both for survivors [F(3,213) = 47.541, R2 = 0.401, p < 0.001] and partners [F(3,215) = 27.917, R2 = 0.280, p < 0.001). Demographic variables were not significant predictors of fear of recurrence. Conclusions As predicted, cognitive processing mediated the relationship between social constraints and fear of recurrence. Results expand the utility of the SCPT in long-term survivors and their partners by supporting its use in intervention design.

    Relationship of Self-reported Attentional Fatigue to Perceived Work Ability in Breast Cancer Survivors
    (Lippincott, Williams, and Wilkins, 2017) Von Ah, Diane; Storey, Susan; Crouch, Adele; Johns, Shelley A.; Dodson, Jill; Dutkevitch, Sarah; IU School of Nursing
    Background: Breast cancer survivors (BCSs) have identified attentional fatigue, a decrease in the ability to focus, as a persistent daily challenge; however, little is known regarding its impact on work ability. Objective: The purpose of this study was to examine the relationship between attentional fatigue and perceived work ability in BCSs controlling for the known covariates of age, education, household income, and time posttreatment. Methods: A cross-sectional, descriptive design was used. Breast cancer survivors who were currently employed and at least 1 year post-adjuvant treatment participated. Breast cancer survivors completed the Attentional Function Index and Work Ability Index questionnaires. Descriptive statistics, linear regression, and Fisher exact test were used for analysis. Results: Sixty-eight female BCSs, ranging from 29 to 68 years of age (mean, 52.1 [SD, 8.6]) and on average 4.97 (SD, 3.36) years posttreatment, participated. More than one-fourth of BCSs (26.5%) reported poor to moderate perceived work ability, indicating substantial concerns regarding work performance. Attentional fatigue was found to significantly predict perceived work ability (P < .001), explaining 40% of the variance of perceived work ability. Conclusions: Attentional fatigue is a prevalent symptom posttreatment that is negatively related to perceived work ability in BCSs. Implications for Practice: Nurses are in a prime position to assess and intervene to alleviate attentional fatigue to improve work ability. Findings suggest a need for individual, comprehensive survivorship care plans to effectively address symptoms that impact work ability and, ultimately, the quality of life of cancer survivors.

    The Experience of Peripheral Neuropathy Symptoms in Breast Cancer Survivors With Diabetes
    (Wolters Kluwer, 2024-07) Storey, Susan; Draucker, Claire; Haunert, Laura; Von Ah, Diane; School of Nursing
    Background Diabetes (type 2) is a risk factor for developing peripheral neuropathy (PN) symptoms in breast cancer survivors (BCS). Because PN symptoms are associated with deficits in physical functioning and quality of life, more information is needed about the effects of PN symptoms on the lives of BCS with diabetes. Objective The aim of this study was to describe the experiences of PN among BCS with diabetes from their own perspectives. Interventions/Methods This substudy is part of a larger investigation examining factors associated with cancer-related cognitive impairment in cancer survivors. Female early-stage (stage I–III) BCS with diabetes and PN symptoms were eligible to participate. A qualitative descriptive approach using purposive sampling and semistructured interviews was used. Participant narratives were summarized using standard content analytic techniques. Results Eleven BCS with diabetes and PN symptoms were interviewed. Participants described PN symptoms that were varied, were often persistent, and had troublesome effects on their physical functioning and quality of life. Participants used a variety of self-management strategies and prescription and over-the-counter medications to manage their PN symptoms. Some said that having both cancer and diabetes exacerbated the PN symptoms and complicated symptom management. Conclusion Peripheral neuropathy symptoms can have a profound effect on the lives of BCS with diabetes and should be addressed by healthcare providers.
