Momentary Partner Involvement in Diabetes Self-Care and Continuously Measured Glucose: A Dynamic Analysis.

OBJECTIVE: This study examined the dynamic, real-time associations between partner involvement in diabetes self-care and continuous glucose monitor (CGM) metrics in adults with type 2 diabetes. METHODS: For 1 week, 63 participants wore Dexcom G4 CGMs and provided momentary reports of partner involvement in diabetes self-care five times per day. Dynamic structural equation models were used to estimate the reciprocal lagged effects of partner involvement on next-hour CGM metrics (and vice versa). RESULTS: Partner involvement predicted improved next-hour glucose control for five of six CGM metrics in analyses adjusted for time-varying covariates. The hour after partner involvement, the model predicted a 26.34 mg/dl decrease in glucose level (standardized ß = -0.19), 30% greater odds of meeting target time in target range ( ß = 0.07), 48% higher odds of target time below target range (TBR; ß = 0.04; the only nonsignificant effect), 47% greater odds of target time above target range (ß = 0.11), a 4.20 unit decrease in glucose standard deviation ( ß = -0.19), and a 0.01 unit decrease in glucose coefficient of variation ( ß = -0.08; all p values < .05). There was less consistent support for the reverse pathway, with only two metrics significantly related to next-hour partner involvement: glucose level ( ß = 0.15) and TBR ( ß = 0.21), such that having higher levels and meeting target TBR were significantly predictive of next-hour partner involvement. CONCLUSIONS: This is the first study showing that partner involvement in daily diabetes management predicts short-term glucose control. More research is needed to understand how partners influence glycemic control and evaluate interventions that promote their involvement in diabetes care.

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.

Impact of Relationship and Communication Variables on Ambulatory Blood Pressure in Advanced Cancer Caregivers.

BACKGROUND: Cancer impacts both patients and their family caregivers. Evidence suggests that caregiving stress, including the strain of taking on a new role, can elevate the risk of numerous health conditions, including high blood pressure (BP). However, the caregiver's psychosocial experiences, including their interpersonal relationship with the patient, may buffer some of the negative physiological consequences of caregiving. PURPOSE: To examine the influence of psychosocial contextual variables on caregiver ambulatory BP. METHODS: Participants were 81 spouse-caregivers of patients with advanced gastrointestinal or thoracic cancer. For an entire day at home with the patient, caregivers wore an ambulatory BP monitor that took readings at random intervals. Immediately after each BP reading, caregivers reported on physical circumstances (e.g., posture, activity) and psychosocial experiences since the last BP measurement, including affect, caregiver and patient disclosure, and role perceptions (i.e., feeling more like a spouse vs. caregiver). Multilevel modeling was used to examine concurrent and lagged effects of psychosocial variables on systolic and diastolic BP, controlling for momentary posture, activity, negative affect, and time. RESULTS: Feeling more like a caregiver (vs. spouse) was associated with lower systolic BP at the same time point. Patient disclosure to the caregiver since the previous BP reading was associated with higher diastolic BP. No lagged effects were statistically significant. CONCLUSIONS: Caregivers' psychosocial experiences can have immediate physiological effects. Future research should examine possible cognitive and behavioral mechanisms of these effects, as well as longer-term effects of caregiver role perceptions and patient disclosure on caregiver psychological and physical health.

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.

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.

Feasibility and Acceptability of Ecological Momentary Assessment of Psychosocial Factors and Self-Management Behaviors Among Veterans With Type 2 Diabetes.

Comorbid symptoms such as post-traumatic stress and pain are common barriers to optimal self-management among veterans with type 2 diabetes. Additionally, self-management behaviors occur in the context of veterans' daily routines and social environments. This study evaluated the feasibility and acceptability of ecological momentary assessment (EMA) among veterans with type 2 diabetes. Ten veterans with type 2 diabetes were asked to respond to random EMA surveys during preprogrammed intervals five times per day for 14 days. EMA surveys were delivered via a mobile application and assessed momentary physical location, activities, social interactions, mood, stress, and pain. The last survey of each day included additional items about daily post-traumatic stress symptoms, diabetes distress, social support, physical activity, self-management behaviors, and functioning. Participants completed interviews assessing their experience in the study and barriers to responding and indicated their likelihood of participating in similar studies. The mean survey response rate was 96%, providing 675 observations. The majority of participants completed the five momentary surveys in <1 minute and the daily EMA surveys in <5 minutes. Results revealed substantial individual day-to-day variability across symptoms and self-management behaviors that is not captured by aggregated means across all participants. Participants generally reported enjoying responding to surveys and experiencing few barriers. Nine of 10 participants reported being "extremely likely" to participate in a similar study. These pilot data suggest that intensive EMA designs are feasible and acceptable for veterans with type 2 diabetes and can inform the design of future larger studies.

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

BACKGROUND: Withholding cancer-related concerns from one's partner (protective buffering) and feeling that one's partner is inaccessible or unresponsive to such disclosure (social constraints) are two interpersonal interaction patterns that separately have been linked to poorer adjustment to cancer. PURPOSE: Guided by the Social-Cognitive Processing Model, we examined the joint effects of social constraints and protective buffering on fear of cancer recurrence (FCR) in survivors and spouses. Social constraints and protective buffering were hypothesized to emerge as independent predictors of higher FCR. METHODS: Early-stage breast cancer survivors and spouses (N = 79 couples; 158 paired individuals) completed up to five repeated measures of FCR, social constraints, protective buffering, and relationship quality during the year postdiagnosis. A second-order growth curve model was estimated and extended to test the time-varying, within-person effects of social constraints and protective buffering on a latent FCR variable, controlling for relationship quality. RESULTS: As hypothesized, greater social constraints and protective buffering significantly (p < .05) predicted higher concurrent FCR at the within-person level, controlling for global relationship quality and change in FCR over time. The fixed effects were found to be similar for both survivors and spouses. CONCLUSIONS: Findings suggest that interaction patterns resulting in inhibited disclosure are associated with greater FCR for both survivors and spouses, consistent with the Social-Cognitive Processing Model. This work adds to the growing body of research highlighting the social context of FCR.

Spousal Influence on Diabetes Self-care: Moderating Effects of Distress and Relationship Quality on Glycemic Control.

BACKGROUND: Spouses often attempt to influence patients' diabetes self-care. Spousal influence has been linked to beneficial health outcomes in some studies, but to negative outcomes in others. PURPOSE: We aimed to clarify the conditions under which spousal influence impedes glycemic control in patients with type 2 diabetes. Spousal influence was hypothesized to associate with poorer glycemic control among patients with high diabetes distress and low relationship quality. METHODS: Patients with type 2 diabetes and their spouses (N = 63 couples) completed self-report measures before patients initiated a 7-day period of continuous glucose monitoring. Mean glucose level and coefficient of variation (CV) were regressed on spousal influence, diabetes distress, relationship quality, and their two- and three-way interactions. RESULTS: The three-way interaction significantly predicted glucose variability, but not mean level. Results revealed a cross-over interaction between spousal influence and diabetes distress at high (but not low) levels of relationship quality, such that spousal influence was associated with less variability among patients with low distress, but more among those with high distress. Among patients with high distress and low relationship quality, a 1 SD increase in spousal influence predicted a difference roughly equivalent to the difference between the sample mean CV and a CV in the unstable glycemia range. CONCLUSIONS: This was the first study to examine moderators of the link between spousal influence and glycemic control in diabetes. A large effect was found for glucose variability, but not mean levels. These novel results highlight the importance of intimate relationships in diabetes management.

Everyday protective buffering predicts intimacy and fear of cancer recurrence in couples coping with early-stage breast cancer.

OBJECTIVE: Patient and spouse/partner mutual self-disclosure is central for maintaining intimacy and cognitive processing when transitioning to life after cancer. Protective buffering inhibits self-disclosure and is defined as efforts to protect one's partner from upset and burden by hiding or denying cancer-related concerns. Intimacy and fear of cancer recurrence (FCR) are important determinants of individual and couple adaptation following cancer. Links between protective buffering and intimacy have not been examined in the context of daily life, and links with FCR have not been studied. We hypothesized that protective buffering is associated with decreased intimacy and increased FCR at a daily, within-person level. METHODS: Sixty-nine early-stage breast cancer (BC) survivors and their spouses completed electronic diaries for 21 consecutive days at the end of adjuvant treatment. Patients and spouses reported on daily protective buffering, intimacy, and FCR. Dyadic multilevel path modeling was used to estimate within-person effects. Patient and spouse protective buffering on one's own as well as one's partner's same-day intimacy and FCR were examined, controlling for previous levels of intimacy and FCR. RESULTS: Protective buffering was associated with decreased intimacy and increased FCR for the individual reporting buffering that same day. Patient and spouse protective buffering was also linked to decreased intimacy for her/his partner that same day. Moreover, patient protective buffering predicted increased spouse FCR that same day. CONCLUSIONS: Findings supported a daily, within-person link between buffering, intimacy, and FCR, suggesting open disclosure of cancer-related concerns may be a relevant target for interventions for adaptation to BC.

Checking Behavior, Fear of Recurrence, and Daily Triggers in Breast Cancer Survivors.

BACKGROUND: Fear of cancer recurrence (FCR) is a top ongoing concern of breast cancer (BC) survivors and thus the focus of recent intervention development. The Self-Regulation Model of FCR (Lee-Jones C, Humphris G, Dixon R, Hatcher MB. Fear of cancer recurrence-a literature review and proposed cognitive formulation to explain exacerbation of recurrence fears. Psychooncology. 1997;6:95-105.) states that everyday cancer-related events trigger FCR, which, in turn, leads to specific behavioral responses, including checking the body for signs or symptoms of cancer. Links between triggering events, FCR, and checking behavior have not yet been studied in the context of daily life or at the within-person level. PURPOSE: The goal of this study was to examine whether FCR has a within-person link with daily checking behavior and whether FCR mediates the link between triggering events and checking behavior. METHODS: Seventy-two early-stage BC survivors completed daily diaries over a 21-day period approximately 5 months after BC surgery. FCR, checking behavior, and triggering events were assessed each evening. RESULTS: Multilevel modeling results indicated that FCR predicted greater odds of same-day, but not next-day, checking behavior. We found that daily FCR significantly mediated the same-day effect of triggering events on checking behavior. These average within-person effects varied substantially between patients and were not explained by momentary negative affect. CONCLUSIONS: Findings support the within-person relationship between triggering events, FCR, and checking behavior posited by guiding theory, and can inform FCR intervention development.

Threat sensitivity and fear of cancer recurrence: a daily diary study of reactivity and recovery as patients and spouses face the first mammogram post-diagnosis.

OBJECTIVES: Fear of cancer recurrence (FCR) is a top concern of breast cancer (BC) survivors and their spouses, yet little is known about responses to FCR triggers in daily life. We examined whether a biologically based individual difference-threat sensitivity-predicted FCR in couples facing the first post-diagnosis mammogram (MMG). We hypothesized that threat sensitivity would predict greater FCR reactivity before the MMG and higher peak FCR on the MMG day, controlling for global anxiety. We also explored the link between threat sensitivity and FCR recovery after MMG. DESIGN AND SAMPLE: Fifty-seven early-stage BC patients and their spouses completed cross-sectional measures of threat sensitivity and global anxiety. Couples then reported daily FCR during a 3-week diary period that began 2 weeks before the patient's MMG appointment. METHODS: Multilevel actor-partner interdependence modeling was used to estimate within-person random slopes of FCR before (reactivity) and after (recovery) the MMG. Random intercepts captured individual differences in peak FCR on the MMG day. Patient and spouse threat sensitivity and anxiety were entered as predictors of reactivity, peak, and recovery. FINDINGS: FCR increased leading to MMG; however, inconsistent with hypotheses, this reactivity was not significantly predicted by threat sensitivity. Actor, but not partner, effects for peak FCR emerged, such that patients and spouses with greater threat sensitivity had greater FCR on the MMG day. FCR decreased after the MMG, and spouse, but not patient, threat sensitivity predicted slower recovery for both partners. CONCLUSIONS: Findings lend preliminary support for the role of threat sensitivity in the experience of FCR as couples confront threatening events in BC survivorship. Implications for psychosocial providers: MMGs can be a triggering event for couples. Threat sensitivity may help identify those who are likely to experience elevations in FCR during this stressful period.

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: 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. RESULTS: 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.

Partner Pronoun Use, Communal Coping, and Abstinence during Couple-Focused Intervention for Problematic Alcohol Use.

Communal coping-a process in which romantic partners view a problem as ours rather than yours or mine, and take collaborative action to address it -has emerged as an important predictor of health and treatment outcomes. In a study of partners' pronoun use prior to and during couple-focused alcohol interventions, we examined first-person plural (we-talk) and singular (I-talk) pronouns as linguistic markers of communal coping and behavioral predictors of treatment outcome. Thirty-three couples in which one partner abused alcohol were selected from a randomized control trial (N = 63) of couple-focused Cognitive-Behavioral or Family Systems Therapy if they had unambiguously successful or unsuccessful treatment outcomes (i.e., patient maintained abstinence for 30 days prior to treatment termination or had more than one heavy drinking day in the same period). Pronoun measures for each partner were obtained via computerized text analysis from transcripts of partners' speech, derived from a videotaped pretreatment interaction task and three subsequent therapy sessions. Spouse we-talk during the intervention (accounting for pretreatment we-talk), as an index of communal orientation, uniquely predicted successful treatment outcomes. In contrast, both patient and spouse I-talk during the intervention (accounting for pretreatment I-talk), as a marker of individualistic orientation, uniquely predicted unsuccessful outcomes, especially when distinguishing active and passive (I vs. me/my) pronoun forms. Results strengthen evidence for the prognostic significance of spouse behavior for patient health outcomes and for communal coping (indexed via pronoun use) as a potential mechanism of change in couple-focused interventions for health problems.

A Semantic Corpus Comparison Analysis of Couple-Focused Interventions for Problematic Alcohol Use.

Incorporating spouses into interventions for problematic alcohol use is associated with increased efficacy; yet, little is known about the therapeutic processes that may explain these effects. In a study of partner language use during couple-focused alcohol interventions, we utilized a linguistic corpus comparison tool, Wmatrix, to identify semantic themes that differentiated couples with successful and unsuccessful treatment outcomes and may therefore also reflect potential change processes. Thirty-three couples participated in a randomized control trial of Family Systems Therapy (FST) or Cognitive Behavioural Therapy (CBT). Linguistic comparisons of partners' speech during the therapy sessions suggested that drinks and alcohol was a significant differentiating semantic theme. Specifically, patients and spouses in FST with successful outcomes used more language related to drinks and alcohol than patients and spouses in FST with unsuccessful outcomes. Post-hoc analyses of context suggested that, in FST, successful spouses spoke less about the patient's drinking and more about alcohol in general (without reference to an individual) than unsuccessful spouses. Conversely, spouses in CBT with successful outcomes used less language related to drinks and alcohol than spouses in CBT with unsuccessful outcomes. In CBT, successful spouses spoke more about the patient's and couple's drinking and less about the spouse's and other people's drinking than unsuccessful spouses. Results emphasize the role of spouse behaviour-in this case indexed via language use-in alcohol treatment outcomes. Findings also suggest potentially distinct therapeutic processes in FST and CBT and highlight the utility of linguistic corpus comparison methods in couple-focused intervention research. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Incorporating spouses into interventions for problematic alcohol use is associated with increased efficacy; yet, little is known about the specific therapeutic processes that may explain these effects. Findings from this study suggest that semantic themes such as drinks and alcohol in partner speech during therapy sessions differentiate successful and unsuccessful treatment outcomes among couples participating in two couple-focused interventions for problematic alcohol use. In addition, the context in which partners used alcohol-related language differed by intervention type and treatment outcome, which suggests potential therapeutic processes that are unique to the two interventions (Family Systems versus Cognitive Behavioural Therapy).

The Potential Impact of Continuous Glucose Monitoring Use on Diabetes-Related Attitudes and Behaviors in Adults with Type 2 Diabetes: A Qualitative Investigation of the Patient Experience.

Background: Despite the known glycemic benefits of continuous glucose monitoring (CGM) for adults with type 2 diabetes (T2D), the attitudinal and behavioral changes underlying these glycemic improvements remain understudied. This study aimed to qualitatively explore these changes among a sample of adults with T2D. Methods: In-depth, semistructured interviews were conducted with adults with T2D who had been using CGM for 3-6 months as part of a larger community project in Ohio. Thematic analysis was used to identify themes across participants' experiences. Results: A total of 34 participants provided insights into their experiences with CGM. Six primary themes emerged: (1) Making the Invisible Visible, highlighting the newfound awareness of T2D in daily life. (2) Effective Decision-Making, emphasizing the use of real-time glucose data for immediate and long-term choices. (3) Enhanced Self-Efficacy, describing a renewed sense of control and motivation. (4) Diabetes-Related Diet Modifications. (5) Changes in Physical Activity. (6) Changes in Medication Taking. Conclusions: Participants reported a far-reaching impact of CGM on their daily lives, with many stating that CGM fostered a greater understanding of diabetes and prompted positive behavior changes. The observed attitudinal and behavioral shifts likely contributed synergistically to the significant glycemic benefits observed over the study period. This study highlights the technology's potential to bring about meaningful attitudinal and behavioral changes.

Addressing emotional distress to improve outcomes in adults with type 1 diabetes: Protocol for ACT1VATE randomized controlled trial.

BACKGROUND: Diabetes distress (DD) is a prevalent concern among people with type 1 diabetes (T1D) and is linked to poor clinical outcomes. Instead of targeting the elimination of DD, we propose a novel approach that empowers individuals with strategies to manage their diabetes effectively in the context of DD: Acceptance and Commitment Therapy (ACT). The purpose of this in-progress trial is to compare an ACT group intervention (ACT1VATE) with usual care in improving HbA1c, DD, quality of life, and cost-effectiveness in adults with T1D. METHODS: This is a two-arm, parallel group, randomized controlled superiority trial enrolling N = 250 adults with T1D, elevated HbA1c, and significant DD in a real-world community-based health system. Participants are randomized to receive ACT1VATE (a five-week ACT group telehealth intervention) or diabetes self-management education and support (usual care as the first-line recommended intervention for DD). The trial will examine comparative effectiveness in improving HbA1c, DD, quality of life, and cost-effectiveness over 12 months. DISCUSSION: We predict that ACT1VATE will be superior given its (1) specific focus on DD, without any expectation that difficult diabetes-related thoughts and emotions must (or can) be completely eliminated; and (2) purposeful linkage of diabetes self-care behaviors to an individual's deeply held values, thus eliciting intrinsic, patient-centric motivation for meaningful and lasting health behavior changes. This trial will provide a valuable test of real-world effectiveness, drive sustainability and scalability, and inform the future of chronic disease care. TRIAL REGISTRATION: NCT04933851 (https://clinicaltrials.gov/ct2/show/NCT04933851). CLINICAL TRIAL: Clinicaltrials.govNCT04933851https://clinicaltrials.gov/study/NCT04933851.

Fear of cancer recurrence and change in hair cortisol concentrations in partners of breast cancer survivors.

PURPOSE: Partners of breast cancer (BC) survivors report high rates of psychological distress including fear of cancer recurrence (FCR). Research suggests that partners may have poorer physical health outcomes than the general population, but little research has examined the physiological biomarkers by which distress may impact partner health outcomes. The current study examined the associations between FCR and changes in hair cortisol among BC partners. METHODS: Male partners (N = 73) of early-stage BC survivors provided hair samples during two visits, one after completion of survivors' adjuvant treatment (T1) and again 6 months later (T2). Two subscales from the Fear of Cancer Recurrence Inventory and one subscale from the Concerns about Recurrence Scale comprised a latent FCR factor at T1. A latent change score model was used to examine change in cortisol as a function of FCR. RESULTS: Partners were on average 59.65 years of age (SD = 10.53) and non-Hispanic White (83%). Latent FCR at T1 was positively associated (b = 0.08, SE = 0.03, p = .004, standardized ß = .45) with change in latent hair cortisol from T1 to T2. CONCLUSIONS: Results indicated that greater FCR was associated with increases in hair cortisol in the months following adjuvant treatment. This is one of the first studies to examine the physiological correlates of FCR that may impact health outcomes in BC partners. IMPLICATIONS FOR CANCER SURVIVORS: Findings highlight the need for further research into the relationship between FCR and its physiological consequences. Interventions to address partner FCR are needed and may aid in improving downstream physical health outcomes.

Romantic relationships and type 2 diabetes: The role of invisible social control.

OBJECTIVE: This study aimed to determine whether invisible social control provided by a romantic partner is associated with improved objective glucose outcomes for patients with Type 2 diabetes. Social control reflects a partner's attempt to modify or influence a patient's health behaviors. We hypothesized that the best outcome for all continuous glucose monitoring measures would be captured by an interaction condition reflecting invisible social control. METHOD: Patients with Type 2 diabetes and their partners (N = 63 couples) completed an 8-day daily diary period between 2016 and 2017. Self-report measures of social control receipt and provision were obtained each evening from patients and partners and patients wore a continuous glucose monitor throughout the diary period. Outcomes of daily glucose mean, standard deviation, time in range, and coefficient of variation were computed and two-way interactions between social control receipt and social control provision were probed and plotted. RESULTS: The two-way interaction significantly predicted daily glucose mean, standard deviation, and time in range, such that when patients reported no social control receipt, but partners reported social control provision, patients showed improvements in objective glucose measures. We found no significant effect for coefficient of variation. CONCLUSIONS: This study was the first to use an invisible social control framework to examine the daily dyadic associations between partner social control provision, patient social control receipt, and four objectively measured continuous glucose monitoring outcomes. Findings suggest that the visibility of social control provided by a romantic partner may be predictive of glycemic control in patients with Type 2 diabetes.

Outcomes of the Dulce Digital-COVID Aware (DD-CA) discharge texting platform for US/Mexico border Hispanic individuals with diabetes.

BACKGROUND: Hispanic individuals have higher type 2 diabetes (T2D) prevalence, poorer outcomes, and are disproportionately affected by COVID-19. Culturally-tailored, diabetes educational text messaging has previously improved HbA1c in this population. METHODS: During the pandemic, hospitalized Hispanic adults with T2D (N = 172) were randomized to receive Dulce Digital-COVID Aware ("DD-CA") texting platform upon discharge plus diabetes transition service (DTS) or DTS alone. DD-CA includes diabetes educational messaging with additional COVID-safe messaging (e.g., promoting masking; social distancing; vaccination). FINDINGS: Among adults with poorly-controlled diabetes (Mean HbA1c = 9.6 ± 2.2 %), DD-CA did not reduce 30- or 90-day readmissions compared to standard care (28 % vs 15 %, p = .06; 37 % vs 35 %, p = .9, respectively). However, the improvement in HbA1c was larger among those in the DD-CA compared to DTS at 3 months (n = 56; -2.69 % vs. -1.45 %, p = .0496) with reduced effect at 6 months (n = 64; -2.03 % vs -0.91 %, p = .07). Low follow-up completion rates and the addition of covariates (to control for baseline group differences that existed despite randomization) impacted statistical power. INTERPRETATION: During the pandemic, DD-CA offered an alternative digital approach to diabetes and COVID education and support for a high-risk Hispanic population and achieved trends toward improvement in glycemic control despite relatively low engagement and not reducing hospital readmissions.

Medical Assistant Health Coaching for Type 2 Diabetes in Primary Care: Results From a Pragmatic Cluster Randomized Controlled Trial.

OBJECTIVE: This cluster (clinic-level) randomized controlled trial (RCT) compared medical assistant (MA) health coaching (MAC) with usual care (UC) among at-risk adults with type 2 diabetes in two diverse real-world primary care environments: a federally qualified health center (FQHC; Neighborhood Healthcare) and a large nonprofit private insurance-based health system (Scripps Health). RESEARCH DESIGN AND METHODS: A total of 600 adults with type 2 diabetes who met one or more of the following criteria in the last 90 days were enrolled: HbA1c ≥8% and/or LDL cholesterol ≥100 mg/dL and/or systolic blood pressure (SBP) ≥140 mmHg. Participants at MAC clinics received in-person and telephone self-management support from a specially trained MA health coach for 12 months. Electronic medical records were used to examine clinical outcomes in the overall sample. Behavioral and psychosocial outcomes were evaluated in a subsample (n = 300). RESULTS: All clinical outcomes improved significantly over 1 year in the overall sample (P < 0.001). The reduction in HbA1c was significantly greater in the MAC versus UC group (unstandardized Binteraction = -0.06; P = 0.002). A significant time by group by site interaction also showed that MAC resulted in greater improvements in LDL cholesterol than UC at Neighborhood Healthcare relative to Scripps Health (Binteraction = -1.78 vs. 1.49; P < 0.05). No other statistically significant effects were observed. CONCLUSIONS: This was the first large-scale pragmatic RCT supporting the real-world effectiveness of MAC for type 2 diabetes in U.S. primary care settings. Findings suggest that this team-based approach may be particularly effective in improving diabetes outcomes in FQHC settings.
