A randomized controlled trial of a distress screening, consultation, and targeted referral system for family caregivers in oncologic care.

OBJECTIVE: Distress screening is standard practice among oncology patients, yet few routine distress screening programs exist for cancer caregivers. The objective of this study was to demonstrate the feasibility, acceptability, and preliminary efficacy of Cancer Support Source-CaregiverTM (CSS-CG, 33-item), an electronic distress screening and automated referral program with a consultation (S + C) to improve caregiver unmet needs, quality of life, anxiety, depression, and distress relative to Enhanced Usual Care (EUC; access to educational materials). METHOD: 150 caregivers of patients with varying sites/stages of cancer were randomized to S + C or EUC and completed assessments at baseline, 3-months post-baseline, and 6-months post-baseline. A subset of participants (n = 10) completed in-depth qualitative interviews. RESULTS: S + C was feasible: among 75 caregivers randomized to S + C, 66 (88%) completed CSS-CG and consultation. Top concerns reported were: (1) patient's pain and/or physical discomfort; (2) patient's cancer progressing/recurring; and (3) feeling nervous or afraid. Differences between groups in improvements on outcomes by T2 and T3 were modest (ds < 0.53) in favor of S + C. Qualitative data underscored the helpfulness of S + C in connecting caregivers to support and helping them feel cared for and integrated into cancer care. CONCLUSIONS: S + C is feasible, acceptable, and yields more positive impact on emotional well-being than usual care. Future studies will examine programmatic impact among caregivers experiencing higher acuity of needs, and benefits of earlier integration of S + C on caregiver, patient, and healthcare system outcomes.

Sleep and Caregiver Burden Among Caregivers of Persons Living With Dementia: A Scoping Review.

Background and Objectives: Caregivers of persons with dementia report worse sleep when compared to the general population. The objective of this review was to synthesize evidence regarding the link between caregiver burden and dementia caregivers' sleep. Research Design and Methods: We conducted a scoping review using a systematic search for pertinent literature in PubMed, CINAHL, and Web of Science through March 2022. Keywords included content areas of dementia, caregiver burden, and sleep. Inclusion criteria were informal caregivers of persons living with dementia, a measured relationship between informal dementia caregiver sleep and subjective caregiver burden variables, and original research. Non-English studies were excluded. Extracted data were organized in tables, compared, and synthesized. Results: The search yielded 540 nonduplicate articles screened by title and abstract; 118 full-text articles were reviewed; 24 were included. Most studies were cross-sectional, with variable sample sizes. Dementia caregivers had significantly poorer overall perceived sleep than noncaregivers across 4 studies that examined self-reported sleep measures. Eighteen studies investigated the association between caregiver burden and self-reported sleep quality, with 14 reporting a significant positive association between caregiver burden and self-reported sleep quality, and 4 finding null results. Only 2 of the 4 studies reporting the association between caregiver burden and objective sleep parameters (ie, actigraphy and polysomnography) reported a significant positive association for at least one sleep subdomain. Discussion and Implications: Although subjective sleep quality is commonly affected by dementia caregiving burden, there is a lack of corresponding evidence on the relationship between burden and objective sleep metrics. Healthcare providers should consider the dementia caregiver burden's impact on sleep and regularly assess caregivers' sleep difficulties. Future studies should focus on consistently measuring caregiver burden and sleep to promote dementia caregiver health and well-being.

Mobile sensing to advance tumor modeling in cancer patients: A conceptual framework.

As mobile and wearable devices continue to grow in popularity, there is strong yet unrealized potential to harness people's mobile sensing data to improve our understanding of their cellular and biologically-based diseases. Breakthrough technical innovations in tumor modeling, such as the three dimensional tumor microenvironment system (TMES), allow researchers to study the behavior of tumor cells in a controlled environment that closely mimics the human body. Although patients' health behaviors are known to impact their tumor growth through circulating hormones (cortisol, melatonin), capturing this process is a challenge to rendering realistic tumor models in the TMES or similar tumor modeling systems. The goal of this paper is to propose a conceptual framework that unifies researchers from digital health, data science, oncology, and cellular signaling, in a common cause to improve cancer patients' treatment outcomes through mobile sensing. In support of our framework, existing studies indicate that it is feasible to use people's mobile sensing data to approximate their underlying hormone levels. Further, it was found that when cortisol is cycled through the TMES based on actual patients' cortisol levels, there is a significant increase in pancreatic tumor cell growth compared to when cortisol levels are at normal healthy levels. Taken together, findings from these studies indicate that continuous monitoring of people's hormone levels through mobile sensing may improve experimentation in the TMES, by informing how hormones should be introduced. We hope our framework inspires digital health researchers in the psychosocial sciences to consider how their expertise can be applied to advancing outcomes across levels of inquiry, from behavioral to cellular.

Correlates of posttraumatic stress in cancer patients and their family caregivers across two years following diagnosis.

OBJECTIVE: To examine risk-factors of cancer-related PTSS in the 2-years post-diagnosis in adult colorectal cancer patients and caregivers. METHODS: Patients with colorectal cancer and their caregivers (N = 130 dyads) self-reported sociodemographic, psychosocial, and medical factors at diagnosis/treatment initiation (T1), at 1- (T2), and 2-year (T3) post-diagnosis. Cancer-related PTSS were assessed, and path analysis examined associations between proposed correlates and PTSS. RESULTS: Among patients, higher neuroticism and greater physical symptom distress were concurrently associated with higher PTSS (Bs ≥ 0.10, ps ≤ 0.02); greater physical symptom distress at T1 and greater social support at T2 were associated with higher PTSS at T3 (Bs ≥ 0.37, ps ≤ 0.04). Among caregivers, female gender, higher neuroticism (Bs ≥ 0.12, ps < 0.01), and lower social support (Bs  ≤ -0.24, ps ≤ 0.02) were associated with higher concurrent PTSS; lower patient physical symptom distress and social support at T1 (Bs  ≤ -0.27, ps ≤ 0.03) and longer hours spent caregiving at T2 (B = 0.03, p = 0.05) were associated with higher PTSS at T3. CONCLUSIONS: Findings identify cancer-specific risk factors (physical symptoms, hours caregiving), in addition to established risk factors (female, neuroticism, social support) in non-medical populations. The identified subgroups should receive ongoing screening and psychosocial referral for cancer-related PTSS.

Associations between context and affect within the daily lives of cancer caregivers.

PURPOSE: This study used ecological momentary assessment (EMA) to test the association between activity, location, and social company contexts with cancer caregivers' in-the-moment affect to identify precisely when and where to deliver psychological interventions for caregivers. METHODS: Current cancer caregivers (N = 25) received 8 EMA prompts per day for 7 consecutive days. At each prompt, caregivers reported their current positive affect and negative affect, as well as what they were doing, where they were located, and who they were with. Multilevel logistic regressions tested the associations between caregivers' contexts with their own person-mean-centered state (concurrent momentary level) and trait (overall weekly average) positive or negative affect. RESULTS: Caregivers reported lower state negative affect, as well as higher state positive affect, when socializing (ps < .001), when at a public location (ps < .03), and when around their friends, family, spouse/partner, or care recipient (i.e., person with cancer, ps < .02), relative to when not endorsing the context. Caregivers also reported lower state negative affect when eating/drinking or engaging in leisure (ps < .01; but no parallel effects for state positive affect). Caregivers reported higher state negative affect while working, when at their workplace, or when around work colleagues (ps < .001) and lower state positive affect when at home or alone (ps < .03). CONCLUSIONS: Results suggest the pertinence of a behavioral activation framework to mitigate the emotional strain of caregiving. Interventions that facilitate caregivers' ability to socialize with a range of friends and family, including their loved one with cancer, outside of the home may have the strongest positive emotional impact.

Online sleep diaries: considerations for system development and recommendations for data management.

STUDY OBJECTIVES: To present development considerations for online sleep diary systems that result in robust, interpretable, and reliable data; furthermore, to describe data management procedures to address common data entry errors that occur despite those considerations. METHODS: The online sleep diary capture component of the Sleep Healthy Using the Internet (SHUTi) intervention has been designed to promote data integrity. Features include diary entry restrictions to limit retrospective bias, reminder prompts and data visualizations to support user engagement, and data validation checks to reduce data entry errors. Despite these features, data entry errors still occur. Data management procedures relying largely on programming syntax to minimize researcher effort and maximize reliability and replicability. Presumed data entry errors are identified where users are believed to have incorrectly selected a date or AM versus PM on the 12-hour clock. Following these corrections, diaries are identified that have unresolvable errors, like negative total sleep time. RESULTS: Using the example of one of our fully-powered, U.S. national SHUTi randomized controlled trials, we demonstrate the application of these procedures: of 45,598 total submitted diaries, 487 diaries (0.01%) required modification due to date and/or AM/PM errors and 27 diaries (<0.001%) were eliminated due to unresolvable errors. CONCLUSION: To secure the most complete and valid data from online sleep diary systems, it is critical to consider the design of the data collection system and to develop replicable processes to manage data.

Digital health and telehealth in cancer care: a scoping review of reviews.

The COVID-19 pandemic necessitated remote cancer care delivery via the internet and telephone, rapidly accelerating an already growing care delivery model and associated research. This scoping review of reviews characterised the peer-reviewed literature reviews on digital health and telehealth interventions in cancer published from database inception up to May 1, 2022, from PubMed, Cumulated Index to Nursing and Allied Health Literature, PsycINFO, Cochrane Reviews, and Web of Science. Eligible reviews conducted a systematic literature search. Data were extracted in duplicate via a pre-defined online survey. Following screening, 134 reviews met the eligibility criteria. 77 of those reviews were published since 2020. 128 reviews summarised interventions intended for patients, 18 addressed family caregivers, and five addressed health-care providers. 56 reviews did not target a specific phase of the cancer continuum, whereas 48 reviews tended to address the active treatment phase. 29 reviews included a meta-analysis, with results showing positive effects on quality of life, psychological outcomes, and screening behaviours. 83 reviews did not report intervention implementation outcomes but when reported, 36 reported acceptability, 32 feasibility, and 29 fidelity outcomes. Several notable gaps were identified in these literature reviews on digital health and telehealth in cancer care. No reviews specifically addressed older adults, bereavement, or sustainability of interventions and only two reviews focused on comparing telehealth to in-person interventions. Addressing these gaps with rigorous systematic reviews might help guide continued innovation in remote cancer care, particularly for older adults and bereaved families, and integrate and sustain these interventions within oncology.

Dyadic digital health interventions: Their rationale and implementation.

While most psychosocial and behavioral digital health interventions have been designed to be consumed by an individual, intervening at the level of a dyad - two interdependent individuals - can more comprehensively address the needs of both individuals and their relationship. The clinical utility of the dyadic digital health intervention approach, as well as the practical implementation of this design, will be demonstrated via three examples: eSCCIP, FAMS, and OurRelationship.

Development and feasibility of a communication training to assist caregivers with advanced care planning.

OBJECTIVE: Caregivers are critical in advanced care planning (ACP) discussions, which are difficult but necessary to carry out patients' goals of care. We developed and evaluated the feasibility and acceptability of a communication training to equip caregivers of patients with malignant brain tumors with skills to navigate ACP conversations. METHOD: Caregivers completed a 2-h virtual training addressing ACP Discussions with Your Loved One and ACP Discussions with the Medical Team. A pre-training assessment was completed at baseline and a training evaluation was completed one day post-training. A subset of participants completed semi-structured interviews 2 months post-training. RESULTS: Of 15 caregivers recruited, 9 attended the training and 4 completed qualitative interviews. Post-training, 40% felt confident in discussing ACP with loved ones and 67% felt confident doing so with healthcare professionals; 100% reported feeling confident in using skills learned in the training to facilitate these conversations. Data from qualitative interviews highlighted additional benefits of the training in empathic communication skills and fostering social support. SIGNIFICANCE OF RESULTS: Our communication skills training shows promise in supporting caregivers' skills and confidence in engaging in ACP discussions with patients and healthcare providers. A future randomized controlled trial with a larger and more diverse caregiving sample is needed to determine training efficacy.

Effects of an internet-delivered insomnia intervention for older adults: A secondary analysis on symptoms of depression and anxiety.

OBJECTIVE: To test whether an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) program for older adults attenuates symptoms of depression and anxiety. METHODS: Adults aged ≥ 55 with insomnia were randomized to SHUTi-OASIS (Sleep Healthy Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness; N = 207) or Patient Education (PE; N = 104). Depression and anxiety were assessed (HADS-D and HADS-A, respectively) at baseline, post-assessment, and 6- and 12-month follow-ups. RESULTS: Multilevel modeling of HADS-D showed a condition by time interaction (F[3,779] = 3.23, p = .02): SHUTi-OASIS participants reported lower symptoms than PE at post-assessment. There was no such interaction effect for HADS-A (F[3,779] = 2.12, p = .10). Generalized linear modeling showed no moderation of effects by baseline symptom severity. CONCLUSIONS: Participants randomized to Internet-delivered CBT-I showed stable depression and anxiety across time, while control participants' depressive symptoms briefly increased. CBT-I may help prevent development or worsening of psychological distress among older adults with insomnia. TRIAL REGISTRATION: [Registered at ClinicalTrials.gov; identifier removed for anonymity].

Including partners in discussions of sexual side effects from breast cancer: a qualitative study of survivors, partners, and providers.

PURPOSE: Ensuring there are clear standards for addressing cancer-related sexual side effects is important. Currently, there are differences in two leading sets of clinical guidelines regarding the inclusion of survivors' romantic partners into clinical discussions between survivors and their providers about this issue. To help refine guidelines, we examine breast cancer survivor, partner, and oncology provider perspectives about including partners in discussions about cancer-related sexual side effects in a secondary analysis of a broader qualitative study. METHODS: Partnered female breast cancer survivors (N = 29) completed online surveys, and intimate partners of breast cancer survivors (N = 12) and breast oncology providers (N = 8) completed semi-structured interviews. Themes were derived from thematic content analysis. RESULTS: Among survivors who reported a discussion with their provider, fewer than half indicated their partner had been present, despite most survivors expressing it was - or would have been - helpful to include their partner. Partners also largely indicated being included was or would have been helpful, when welcomed by the survivor. Providers similarly emphasized the importance of survivors' autonomy in deciding whether to discuss sexual concerns in the presence of a partner. CONCLUSIONS: Partners were infrequently included in conversations about cancer-related sexual side effects, even though survivors, partners, and providers alike expressed value in these discussions occurring with the couple together - when that is the survivor's preference. Findings suggest future clinical guidelines should emphasize that incorporating partners into clinical discussions about sexual concerns is important for many breast cancer patients. Soliciting and enacting patients' preferences is essential for truly patient-centered care.

Single-Group Trial of an Internet-Delivered Insomnia Intervention Among Higher-Intensity Family Caregivers: Rationale and Protocol for a Mixed Methods Study.

BACKGROUND: Family caregivers are more likely to experience insomnia relative to noncaregivers but have significant barriers to accessing gold standard cognitive behavioral therapy for insomnia treatment. Delivering interventions to caregivers through the internet may help increase access to care, particularly among higher-intensity caregivers who provide assistance with multiple care tasks over many hours per week. Although there are existing internet interventions that have been thoroughly studied and demonstrated as effective in the general population, the extent to which these interventions may be effective for caregivers without tailoring to address this population's unique psychosocial needs has not been studied. OBJECTIVE: The goal of this trial is to determine what tailoring may be necessary for which caregivers to ensure they receive optimal benefit from an existing evidence-based, internet-delivered cognitive behavioral therapy for insomnia program named Sleep Healthy Using the Internet (SHUTi). Specifically, we will test the association between caregivers' engagement with SHUTi and their caregiving context characteristics (ie, caregiving strain, self-efficacy, and guilt) and environment (ie, proximity to care recipient; functional status, cognitive status, and problem behavior of care recipient; and type of care provided). Among caregivers using the program, we will also test the associations between change in known treatment mechanisms (sleep beliefs and sleep locus of control) and caregiving context factors. METHODS: A total of 100 higher-intensity caregivers with significant insomnia symptoms will be recruited from across the United States to receive access to SHUTi in an open-label trial with mixed methods preassessments and postassessments. At postassessment (9 weeks following preassessment completion), participants will be categorized according to their engagement with the program (nonusers, incomplete users, or complete users). Study analyses will address 3 specific aims: to examine the association between caregivers' engagement with SHUTi and their caregiving context (aim 1a); to describe caregivers' barriers to and motivations for SHUTi engagement from open-ended survey responses (aim 1b); and among caregivers using SHUTi, to determine whether cognitive mechanisms of change targeted by SHUTi are associated with differences in caregiving context (aim 2). RESULTS: Institutional review board approvals have been received. Data collection is anticipated to begin in December 2021 and is expected to be completed in 2023. CONCLUSIONS: Findings will inform the next research steps for tailoring and testing SHUTi for optimal impact and reach among caregivers. Beyond implication to the SHUTi program, the findings will be translatable across intervention programs and will hold significant promise to reduce inefficiencies in developing digital health interventions for caregivers while also increasing their impact and reach for this underserved population.

Addressing sexual concerns of female breast cancer survivors and partners: a qualitative study of survivors, partners, and oncology providers about Internet intervention preferences.

PURPOSE: Sexual side effects after breast cancer treatment are common and distressing to both survivors and their intimate partners, yet few receive interventions to address cancer-related sexual concerns. To direct intervention development, this qualitative study assessed the perceptions of female breast cancer survivors, intimate partners of breast cancer survivors, and breast cancer oncology providers about how an Internet intervention for couples may address breast cancer-related sexual concerns. METHODS: Survivors (N = 20) responded to online open-ended surveys. Partners (N = 12) and providers (N = 8) completed individual semi-structured interviews. Data were inductively coded using thematic content analysis. RESULTS: Three primary intervention content areas were identified by the key stakeholder groups: (1) information about and strategies to manage physical and psychological effects of cancer treatment on sexual health, (2) relationship and communication support, and (3) addressing bodily changes and self-image after treatment. Survivors and partners tended to express interest in some individualized intervention private from their partner, although they also emphasized the importance of opening communication about sexual concerns within the couple. Survivors and partners expressed interest in an intervention that addresses changing needs across the cancer trajectory, available from the time of diagnosis and through survivorship. CONCLUSION: Internet intervention for couples to address cancer-related sexual concerns, particularly one that provides basic education about treatment side effects and that evolves with couples' changing needs across the cancer trajectory, was perceived as a valuable addition to breast cancer care by survivors, partners, and providers.

Feasibility of ecological momentary assessment to study depressive symptoms among cancer caregivers.

OBJECTIVE: Ecological momentary assessment (EMA) may help with the development of more targeted interventions for caregivers' depression, yet the use of this method has been limited among cancer caregivers. This study aimed to demonstrate the feasibility of EMA among cancer caregivers and the use of EMA data to understand affective correlates of caregiver depressive symptoms. METHODS: Caregivers (N = 25) completed a depressive symptom assessment (Patient Health Questionnaire-8) and then received eight EMA survey prompts per day for 7 days. EMA surveys assessed affect on the orthogonal dimensions of valence and arousal. Participants completed feedback surveys regarding the EMA protocol at the conclusion of the week-long study. RESULTS: Of 32 caregivers approached, 25 enrolled and participated (78%), which exceeded the a priori feasibility cutoff of 55%. The prompt completion rate (59%, or 762 of 1,286 issued) did not exceed the a priori cutoff of 65%, although completion was not related to caregivers' age, employment status, physical health quality of life, caregiving stress, or depressive symptoms or the patients' care needs (ps > 0.22). Caregivers' feedback about their study experience was generally positive. Mixed-effects location scale modeling showed caregivers' higher depressive symptoms were related to overall higher reported negative affect and lower positive affect, but not to affective variability. CONCLUSIONS: Findings from this feasibility study refute potential concerns that an EMA design is too burdensome for distressed caregivers. Clinically, findings suggest the potential importance of not only strategies to reduce overall levels of negative affect, but also to increase opportunities for positive affect.

Using Graph Representation Learning to Predict Salivary Cortisol Levels in Pancreatic Cancer Patients.

Cortisol is a glucocorticoid hormone that is critical to immune system functioning. Studies show that prolonged exposure to high levels of cortisol can lead to a range of physical health ailments including the progression of tumor growth. The ability to monitor cortisol levels over time can therefore be used to facilitate decision-making during cancer treatment. However, collecting serum or saliva samples to monitor cortisol in situ is inconvenient, costly, and impractical. In this paper, we propose a general predictive modeling process that uses passively sensed actigraphy data to predict underlying salivary cortisol levels using graph representation learning. We compare machine learning models with handcrafted feature engineering and with graph representation learning, which includes Graph2Vec, FeatherGraph, GeoScattering and NetLSD. Our preliminary results generated from data from 10 newly diagnosed pancreatic cancer patients demonstrate that machine learning models with graph representation learning can outperform the handcrafted feature engineering to predict salivary cortisol levels.

Effects of an Internet-Based Cognitive Behavioral Therapy for Insomnia Program on Work Productivity: A Secondary Analysis.

BACKGROUND: Cognitive-behavioral therapy for insomnia (CBT-I) may improve productivity along with insomnia symptoms, but the long-term duration of productivity gains is unknown. PURPOSE: In this secondary analysis, effects of Internet-delivered CBT-I on work-related and daily activity productivity were examined through 1 year post-treatment. METHODS: Adults with chronic insomnia (N = 303) were randomized to Internet-delivered CBT-I (Sleep Healthy Using the Internet [SHUTi]) or to patient education (PE). Participants reported interference with attendance (absenteeism) and productivity (presenteeism) at paid employment and in daily activities outside work on the Work Productivity Activity Impairment scale at baseline, 9 weeks later for postintervention assessment (post-assessment), and 6- and 12-month follow-ups. RESULTS: Participants randomized to SHUTi were about 50% less likely than those in the PE condition to report any absenteeism (logistic regression odds ratio [OR] = 0.48 [95% confidence intervals {CI} = 0.24,0.96]), total impairment (OR = 0.52 [95% CI = 0.29,0.93]), or activity impairment (OR = 0.50 [95% CI = 0.30,0.85]) at post-assessment; however, differences were not detected at 6- or 12-month follow-ups. SHUTi participants also reported lower overall levels of presenteeism (constrained longitudinal data analysis MDiff = -6.84 [95% CI = -11.53, -2.15]), total impairment (MDiff = -7.62 [95% CI = -12.50, -2.73]), and activity impairment (MDiff = -7.47 [95% CI = -12.68, -2.26]) at post-assessment relative to PE participants. Differences were sustained at 6-month follow-up for presenteeism (MDiff = -5.02 [95% CI = -9.94, -0.10]) and total impairment (MDiff = -5.78 [95% CI = -10.91, -0.65]). No differences were detected by 12-month follow-up. CONCLUSIONS: Findings suggest that Internet-based CBT-I may help accelerate improvement in work-related and daily activity impairment corroborating prior research, but did not find that CBT-I has persistent, long-term benefits in productivity relative to basic insomnia education.

Intraindividual variability in sleep schedule: effects of an internet-based cognitive-behavioral therapy for insomnia program and its relation with symptom remission.

STUDY OBJECTIVES: Sleep schedule consistency is fundamental to cognitive-behavioral therapy for insomnia (CBT-I), although there is limited evidence suggesting whether it predicts treatment response. This analysis tested whether: (1) an Internet-based CBT-I program affects intraindividual variability (IIV) in sleep schedule and (2) sleep schedule IIV predicts insomnia symptom remission. METHODS: This secondary analysis compares participants (N = 303) randomized to an Internet-based CBT-I program (SHUTi-Sleep Healthy Using the Internet) or Internet-based patient education (PE). Participants reported daily bedtimes and rising times on 10 online sleep diaries collected over 2 weeks at baseline and 9-week post-intervention assessment. Participants completed the Insomnia Severity Index (ISI) at post-assessment and 6-month follow-up; symptom remission was defined by ISI < 8. Mixed effects location scale modeling was used to examine the effect of SHUTi on bedtime and rising time IIV; a novel two-staged analysis examined the effect of bedtime and rising time IIV on insomnia symptom remission. RESULTS: At post-assessment, SHUTi participants reported about 30% less bedtime and 32% less rising time variability compared to PE (ps < 0.03). Bedtime and rising time IIV was not independently associated with likelihood of insomnia symptom remission at the subsequent time point (ps > 0.18), nor did sleep schedule IIV moderate treatment response (ps > 0.12). CONCLUSIONS: Findings demonstrate that an Internet-delivered CBT-I program can effectively increase users' sleep schedule consistency relative to an educational control. This consistency, however, was not related to treatment outcome when defined by insomnia symptom remission, suggesting that enforcing rigid sleep schedules for patients may not be necessary for treatment success.

Dyadic Psychosocial eHealth Interventions: Systematic Scoping Review.

BACKGROUND: Dyadic psychosocial interventions have been found beneficial both for people coping with mental or physical health conditions as well as their family members and friends who provide them with support. Delivering these interventions via electronic health (eHealth) may help increase their scalability. OBJECTIVE: This scoping review aimed to provide the first comprehensive overview of dyadic eHealth interventions for individuals of all ages affected by mental or physical illness and their family members or friends who support them. The goal was to understand how dyadic eHealth interventions have been used and to highlight areas of research needed to advance dyadic eHealth intervention development and dissemination. METHODS: A comprehensive electronic literature search of PubMed, EMBASE, Cochrane, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO was conducted for articles published in the English language through March 2019. Eligible records described a psychosocial eHealth intervention that intervened with both care recipients and their support person. RESULTS: A total of 7113 records were reviewed of which 101 met eligibility criteria. There were 52 unique dyadic eHealth interventions identified, which were tested across 73 different trials. Of the unique interventions, 33 were conducted among dyads of children and their supporting parent, 1 was conducted with an adolescent-young adult care recipient population, and the remaining 18 were conducted among adult dyads. Interventions targeting pediatric dyads most commonly addressed a mental health condition (n=10); interventions targeting adult dyads most commonly addressed cancer (n=9). More than three-fourths of interventions (n=40) required some human support from research staff or clinicians. Most studies (n=64) specified one or more primary outcomes for care recipients, whereas less than one-fourth (n=22) specified primary outcomes for support persons. Where specified, primary outcomes were most commonly self-reported psychosocial or health factors for both care recipients (n=43) and support persons (n=18). Results of the dyadic eHealth intervention tended to be positive for care recipients, but evidence of effects for support persons was limited because of few studies specifying primary outcomes for supporters. Trials of dyadic eHealth interventions were most commonly randomized controlled trials (RCTs; n=44), and RCTs most commonly compared the dyadic eHealth intervention to usual care alone (n=22). CONCLUSIONS: This first comprehensive review of dyadic eHealth interventions demonstrates that there is substantial, diverse, and growing literature supporting this interventional approach. However, several significant gaps were identified. Few studies were designed to evaluate the unique effects of dyadic interventions relative to individual interventions. There was also limited assessment and reporting of outcomes for support persons, and there were no interventions meeting our eligibility criteria specifically targeting the needs of older adult dyads. Findings highlight areas of research opportunities for developing dyadic eHealth interventions for novel populations and for increasing access to dyadic care.

The Impact of Resilience Factors and Anxiety During Hospital Admission on Longitudinal Anxiety Among Dyads of Neurocritical Care Patients Without Major Cognitive Impairment and Their Family Caregivers.

BACKGROUND/OBJECTIVE: Anxiety is common in patients experiencing neurocritical illness and their family caregivers. Resilience factors like mindfulness and coping skills may be protective against symptoms of emotional distress, including anxiety. Less is known about the interplay of anxiety symptoms and resilience factors between patients and caregivers. The purpose of this study is to examine the trajectory of anxiety symptoms among dyads of neurocritical care patients without major cognitive impairment and their family caregivers and to elucidate the relationship between resiliency (e.g., mindfulness and coping) and anxiety in these dyads. METHODS: Prospective, longitudinal study of adults admitted to the neurological intensive care unit (Neuro-ICU) and their caregivers. Dyads of patients (N = 102) and family caregivers (N = 103) completed self-report measures of mindfulness (Cognitive Affective Mindfulness Scale-Revised) and coping (Measure of Current Status-Part A) during Neuro-ICU hospitalization and anxiety symptoms (anxiety subscale of the Hospital Anxiety and Depression Scale) during hospitalization and at 3- and 6-month follow-up. We used actor-partner interdependence modeling to predict the effect of one's own baseline characteristics on one's own and one's partner's future anxiety symptoms. RESULTS: Rates of clinically significant anxiety symptoms were 40% for patients and 42% for caregivers at baseline. Of these, 20% of patients and 23% of caregivers showed moderate and severe symptoms. Approximately, one-third of patients and caregivers reported clinically significant anxiety symptoms at 3- and 6-month follow-ups, with more than 20% endorsing moderate or severe symptoms. Patients' own baseline mindfulness, coping, and anxiety symptoms were associated with lower anxiety symptoms at all time points (ps < 0.001)-this was also true for caregivers. For both patients and caregivers, one's own baseline mindfulness predicted their partner's anxiety symptoms 3 months later (p = 0.008), but not at 6-month follow-up. CONCLUSIONS: Anxiety symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months following admission. Mindfulness is interdependent and protective against anxiety in dyads at 3-month but not 6-month follow-up. Early, dyad-based interventions may prevent the development of chronic anxiety in patients without major cognitive impairment and caregivers.

Baseline Resilience and Posttraumatic Symptoms in Dyads of Neurocritical Patients and Their Informal Caregivers: A Prospective Dyadic Analysis.

BACKGROUND: Admission to a neuroscience intensive care unit (Neuro-ICU) is sudden and often traumatic for both patients and their informal caregivers. No prior studies have assessed prospectively risk and resiliency factors for chronic posttraumatic symptoms, as well as the potential interdependence between patients' and caregivers' symptoms over time. OBJECTIVE: To analyze the impact of baseline resiliency factors on symptoms of posttraumatic stress (PTS) longitudinally in dyads of patients admitted to the Neuro-ICU and their primary family caregivers. METHODS: We recruited dyads (M = 108) of patients admitted to the Neuro-ICU (total N = 102) and their family caregivers (total N = 103). Dyads completed self-report assessments of PTS and resiliency factors (mindfulness and coping) at baseline in the Neuro-ICU. PTS was measured again at 3- and 6-month follow-up. RESULTS: Clinically significant PTS symptoms were high at baseline in both patients (20%) and caregivers (16%) and remained high through 6 months (25% in patients; 14% in caregivers). Actor-partner interdependence modeling demonstrated that severity of PTS symptoms was predictive of PTS symptoms at subsequent time points (P < 0.001). High baseline mindfulness and coping predicted less severe PTS symptoms in patients and caregivers (P < 0.001) at all time points. Own degree of PTS symptoms at 3 months predicted worse PTS symptoms in one's partner at 6 months, for both patients and caregivers (P = 0.02). CONCLUSIONS: Findings highlight the need to prioritize assessment and treatment of PTS in Neuro-ICU patients and their informal caregivers through a dyadic approach.
