Self-complexity and reactivity to social support receipt

While several studies have shown that support receipt in self-relevant domains may bring about increases in distress by delivering inefficacy cues to the recipient (e.g., Bolger & Amarel, 2007; Burke & Goren, under revision), results also indicate that some individuals are still able to experience benefits of support receipt in self-relevant domains (Burke & Perndorfer, in prep.). The purpose of the present research was to examine whether self-complexity, which has been shown to moderate the relationship between stress and health and well-being, moderates reactivity to support receipt in self-relevant domains. Study 1 (N = 77) attempted to expand past research on self-complexity by introducing measures of the purported cognitive mechanisms by which self-complexity results in affective consequences. Study 2 (N = 77) examined whether self-complexity moderates reactivity to support receipt in self-relevant domains. The results of the analyses did not support the hypothesis that participants low or high in self-complexity react differently to either failure feedback or support receipt in self-relevant domains. While the studies were unable to replicate past studies of self-complexity or provide support for self-complexity moderating reactivity to support receipt, we believe that the novel measures and modified procedures described in this research are contributions to both the self-complexity and social support literature

Multi-modal Predictive Models of Diabetes Progression

With the increasing availability of wearable devices, continuous monitoring of individuals' physiological and behavioral patterns has become significantly more accessible. Access to these continuous patterns about individuals' statuses offers an unprecedented opportunity for studying complex diseases and health conditions such as type 2 diabetes (T2D). T2D is a widely common chronic disease that its roots and progression patterns are not fully understood. Predicting the progression of T2D can inform timely and more effective interventions to prevent or manage the disease. In this study, we have used a dataset related to 63 patients with T2D that includes the data from two different types of wearable devices worn by the patients: continuous glucose monitoring (CGM) devices and activity trackers (ActiGraphs). Using this dataset, we created a model for predicting the levels of four major biomarkers related to T2D after a one-year period. We developed a wide and deep neural network and used the data from the demographic information, lab tests, and wearable sensors to create the model. The deep part of our method was developed based on the long short-term memory (LSTM) structure to process the time-series dataset collected by the wearables. In predicting the patterns of the four biomarkers, we have obtained a root mean square error of 1.67% for HBA1c, 6.22 mg/dl for HDL cholesterol, 10.46 mg/dl for LDL cholesterol, and 18.38 mg/dl for Triglyceride. Compared to existing models for studying T2D, our model offers a more comprehensive tool for combining a large variety of factors that contribute to the disease

Does sharing good news buffer fear of bad news? A daily diary study of fear of cancer recurrence in couples approaching the first mammogram post-diagnosis

Objective The core of fear of cancer recurrence (FCR)-a top concern of couples after successful breast cancer (BC) treatment-is fear of death. Daily relationship processes may be instrumental in regulating FCR as triggers of existential distress are encountered. We tested the hypothesis that daily capitalization, the process of sharing good news (capitalization attempts) to a partner perceived as responsive (responsiveness), buffers patient and spouse FCR as they confront the first mammogram post-diagnosis. Methods Results Fifty-seven early-stage BC survivors and their spouses reported daily FCR, capitalization, and positivity of the disclosed event during a 3-week diary period beginning 2 weeks before the first annual mammogram post-diagnosis. Dyadic multilevel path models estimated within-person effects of patient and spouse capitalization on same-day FCR, controlling for event positivity. Before the mammogram, capitalization attempts were unrelated to FCR, but for patients, responsiveness was predictive of greater same-day FCR. After the mammogram, for both partners, attempts were predictive of greater same-day FCR, yet responsiveness was predictive of lower FCR. Conclusions Findings were largely inconsistent with the hypothesis that capitalization buffers existential distress. However, results revealed novel insights about daily dyadic processes that may characterize within-person adaptation to existential threat. Potential explanations for the differential links between capitalization and FCR based on timing (before versus after threat) and capitalization component (attempts versus responsiveness) are discussed

Fear of Cancer Recurrence and Inhibited Disclosure: Testing the Social-Cognitive Processing Model in Couples Coping With Breast Cancer

Over the first year of breast cancer survivorship, when patients or their intimate partners felt unable to share cancer-related concerns with one another, they reported higher levels of fear of cancer recurrence

Fear of Cancer Recurrence and Sleep in Couples Coping With Early-Stage Breast Cancer

Background Fear of cancer recurrence (FCR) and sleep disturbance are common in cancer survivors. Yet, little research has examined their relationship, and even less is known about what links may exist between these variables among the intimate partners of cancer survivors. Purpose This study examines the relationship between FCR and sleep disturbance in breast cancer survivors and their partners. Using daily sleep data collected at two distinct periods early in survivorship-the completion of adjuvant treatment and the first post-treatment mammogram-higher survivor and partner FCR was hypothesized to predict greater sleep disturbance. Methods Breast cancer survivors and intimate partners (N = 76 couples; 152 individuals) each reported sleep duration, sleep quality, sleep onset latency, and wake after sleep onset each morning of two 21-day sleep diary bursts during the first year post-diagnosis. Three validated measures formed latent FCR factors for survivors and partners, which were used to predict average daily sleep. Results Across both sleep diary bursts, survivor FCR was associated with their own reduced sleep duration, reduced sleep quality, and greater sleep onset latency. Survivor FCR was also associated with their partners' reduced sleep quality and greater sleep onset latency. Partner FCR was associated with their own reduced sleep duration, reduced sleep quality, and greater sleep onset latency. Partner FCR was also associated with survivors' reduced sleep quality. Conclusions Findings revealed intrapersonal and interpersonal associations between FCR and sleep disturbance, addressing gaps in knowledge on FCR and an outcome with known short- and long-term implications for health and mortality

Social constraints and fear of recurrence in couples coping with early stage breast cancer

Fear of cancer recurrence (FCR) is a top concern of breast cancer (BC) survivors and their spouses. FCR often occurs within an interpersonal context, yet there has been little research on relationship processes that may influence FCR in patients and spouses. It was hypothesized that the inhibition of disclosure of cancer-related concerns, thoughts, and feelings because of perceived partner disinterest or avoidance (termed social constraints) would predict greater FCR in BC patients and their spouses both globally and in the context of everyday life. Two studies, 1 cross-sectional (N = 46 couples) and 1 daily diary (21 days; N = 72 couples), were conducted to examine the between-person and within-person associations between social constraints and FCR in early stage BC patients and their spouses. Assessments were conducted about 6 months after BC surgery. Global social constraints predicted greater global FCR in patients and spouses at the cross-sectional level, controlling for anxiety symptoms, relationship quality, and patient age, physical impairment, and BC stage. At the within-person level, results indicated that on days when more social constraints were reported, both partners were more likely to report greater FCR, controlling for momentary negative affect and relationship quality. This study is the first to examine the within-person association between social constraints and FCR. These findings suggest relationship processes, particularly inhibition of disclosure, can uniquely influence the experience of FCR for both BC patients and their spouses, pointing to an important consideration for future research and possible intervention development.

The longitudinal course of emotional and cognitive factors of fear of cancer recurrence in breast cancer patients and their partners

Objective Although fear of cancer recurrence (FCR) has been conceptualized as a multidimensional construct with emotional and cognitive components, little work has distinguished or assessed both components. Further, most existing research has not included intimate partners of cancer patients, although they also experience FCR. This study aimed to (1) determine whether FCR is better conceptualized as a singular or multidimensional construct at the within-person level over time and (2) model the corresponding trajectories in patients and their partners. Methods Female early stage breast cancer patients and their partners (N = 78 couples) completed up to five assessments over the first year post-diagnosis tapping both emotional and cognitive elements of FCR. Multilevel confirmatory factor analysis was used to evaluate FCR's factor structure, and multivariate latent growth curve modeling was used to estimate trajectories of emotional and cognitive FCR. Results FCR was best conceptualized as two distinct but related emotional and cognitive factors. In patients and partners, emotional FCR decreased over the first year post-diagnosis on average, while cognitive FCR did not change over time. Conclusions Findings support the conceptualization of FCR as a multidimensional construct and underscore the potential importance of distinguishing emotional and cognitive components of FCR in future research

Daily partner responsiveness and everyday sleep outcomes in breast cancer survivors and their partners

Purpose Breast cancer (BC) survivors and their intimate partners face several adverse consequences from the cancer experience, including sleep disturbance, which is a common side effect of BC and its treatment. Sleep has been conceptualized and examined as an individual phenomenon despite most adults sharing a bed/room with a partner. Limited research has examined the associations between daily relationship processes and sleep in couples coping with cancer. Using an intensive longitudinal design, the present study examined the daily, within-person links between attempted and perceived partner responsiveness and subjective sleep. Methods Immediately following adjuvant treatment, 72 early-stage BC survivors and their intimate partners (144 paired individuals) reported on daily attempted and perceived partner responsiveness each evening and subjective sleep each morning for 21 consecutive days. Results Survivor and partner reports of partner responsiveness were associated with their own subjective sleep, such that greater attempted and perceived partner responsiveness were associated with improvements in one's own subjective sleep. Effects of one participant's partner responsiveness on their partner's sleep were not observed. Conclusions Findings suggest that among couples coping with early-stage BC, increased partner responsiveness is associated with subsequent improvements in subjective sleep. Implications for cancer survivors Sleep disturbance is a serious concern for BC survivors and their intimate partners. Future research should assess intimacy processes as a potential method to improve BC survivor and partner sleep

Psychosocial Impact of Cancer Care Disruptions in Women With Breast Cancer During the COVID-19 Pandemic

Background: The COVID-19 pandemic caused significant disruptions in cancer care, and preliminary research suggests that these disruptions are associated with increased levels of psychosocial distress among cancer survivors. The purpose of this study was to offer a descriptive report of the psychosocial functioning, perceived risk and fear of cancer progression, and COVID-19 pandemic impact and experiences in a unique, high-risk patient cohort: breast cancer survivors whose cancer treatment was delayed and/or changed due to the COVID-19 pandemic. Methods: This cross-sectional study included 50 women with dual carcinoma in situ, lobular carcinoma in situ, or invasive breast cancer whose cancer surgery was postponed due to the pandemic. As they awaited delayed surgery or shortly after they received delayed surgery, participants completed questionnaires on psychosocial functioning (depression, anxiety, sleep, and quality of life), their perceived risk and fear of cancer progression, patient-provider communication about disruptions in their care, personal impact of the pandemic, worry/threat about COVID-19, and COVID-19 symptoms/diagnoses. Descriptive statistics and bivariate correlations were computed among continuous study variables. Independent samples t-tests explored group differences in psychosocial functioning between survivors who were still awaiting delayed surgery and those who had recently received it. Results: Overall, the sample denied that the pandemic seriously negatively impacted their finances or resource access and reported low-to-moderate levels of psychosocial distress and fear about COVID-19. Twenty-six percent had clinically significant levels of fear of cancer progression, with levels comparable to other recent work. About a third were still awaiting delayed cancer surgery and this group reported lower satisfaction with communication from oncology providers but overall did not seem to report more psychosocial difficulties than those who already had surgery. Conclusion: Shortly before or after primary breast cancer surgery that was delayed due to the COVID-19 pandemic, this sample of survivors appears to be generally managing well psychosocially. However, many psychosocial difficulties (e.g., fear of cancer recurrence/progression) typically have an onset after the completion of treatment, therefore, research should continue to follow this cohort of cancer survivors as the pandemic's direct impact on their care likely increases their risk for these difficulties later in survivorship
