Risk for Complicated Grief After the COVID-19 Death of a Marital Partner in Late Life.

OBJECTIVE: To identify 1) complicated grief symptom clusters among acutely-bereaved older adults who have lost a spouse to COVID-19 and 2) if spousal death due to COVID-19 increased risk of developing probable PGD METHODS: Eighty adults participating in a randomized controlled trial for depression prevention (mean age [± SD] = 70.4 [6.6]) completed the Inventory of Complicated Grief, every 3 months over a maximum of 15 months. Twenty-four percent (n = 19) of participants lost a spouse to COVID-19; 76% (n = 61) lost a spouse to other causes of death. Adjusted linear regression examined the associations between COVID-19 bereavement and six symptom clusters: yearning and preoccupation, anger and bitterness, shock and disbelief, estrangement from others, hallucinations, and behavior change. RESULTS: Compared to the non-COVID-19 group, the COVID-19 bereaved group reported greater shock and disbelief, hallucinations of the deceased, and estrangement from others. COVID-19 death was also associated with higher risk for probable prolonged grief disorder (PGD) at 12 months (odds ratio = 4.38, p = 0.027). CONCLUSIONS: Older adults who have lost a spouse to COVID-19 present with specific symptoms of distress and may eventually require clinical care for PGD.

Poor Sleep is Common in Treatment-Resistant Late-life Depression and Associated With Poorer Antidepressant Response: Findings From the OPTIMUM Clinical Trial.

BACKGROUND: Adults with treatment-resistant late-life depression (TRLLD) have high rates of sleep problems; however, little is known about the occurrence and change in sleep during pharmacotherapy of TRLLD. This analysis examined: (1) the occurrence of insufficient sleep among adults with TRLLD; (2) how sleep changed during pharmacotherapy; and (3) whether treatment outcomes differed among participants with persistent insufficient sleep, worsened sleep, improved sleep, or persistent sufficient sleep. METHODS: Secondary analysis of data from 634 participants age 60+ years in the OPTIMUM clinical trial for TRLLD. Sleep was assessed using the sleep item from the Montgomery-Asberg Depression Rating Scale at the beginning (week-0) and end (week-10) of treatment. The analyses examined whether treatment outcomes differed among participants with persistent insufficient sleep, worsened sleep, improved sleep, or persistent sufficient sleep during depression treatment. RESULTS: About half (51%, n = 323) of participants reported insufficient sleep at baseline. Both persistent insufficient sleep (25%, n = 158) and worsened sleep (10%, n = 62) during treatment were associated with antidepressant nonresponse. Participants who maintained sufficient sleep (26%, n = 164) or who improved their sleep (n = 25%, n = 158) were three times more likely to experience a depression response than those with persistent insufficient sleep or worsened sleep. CONCLUSION: Insufficient sleep is common in TRLLD and it is associated with poorer treatment response to antidepressants.

Rest-Activity Rhythm Characteristics Associated With Depression Symptoms in Stroke Survivors.

OBJECTIVE: To examine which 24-hour rest-activity rhythm (RAR) characteristics are associated with depression symptoms in stroke survivors. DESIGN: Cross-sectional observational study examining associations of RAR characteristics with the presence of depression symptoms adjusting for age, sex, race, and medical comorbidity. SETTING: Community setting. PARTICIPANTS: Stroke survivors: (1) recruited locally (N women=35, N men=28) and (2) a nationally representative probability sample (the National Health and Nutrition Examination Survey [NHANES]; N women=156, N men=124). INTERVENTIONS: None. MEASUREMENTS: Objective RAR characteristics derived from accelerometer recordings including activity onset/offset times and non-parametric measures of RAR strength (relative amplitude), stability (interdaily stability), and fragmentation (intradaily variability). The presence of depression symptoms was categorized using Patient Health Questionnaire scores. RESULTS: In both samples, the only RAR characteristic associated with depression symptoms was intradaily variability (fragmentation): local sample, odds ratio=1.96 [95% confidence interval=1.05-3.63]; NHANES sample, odds ratio=1.34, [95% confidence interval=1.01-1.78]). In the NHANES sample, which included both mild and moderate/severe depression, the association between 24-hour sleep-wake fragmentation and depression symptoms was driven by moderate-to-severe cases. CONCLUSIONS: Stroke survivors with higher levels of RAR fragmentation were more likely to have depression symptoms in both samples. These findings have implications, given prior studies in general samples linking RAR fragmentation with future depression and dementia risk. Research is needed to establish the potential consequences, mechanisms, and modifiability of RAR fragmentation in stroke survivors.

A Multimethod Examination of Medical Students' Experiences With Bereavement and Complicated Grief.

Few studies have examined grief in medical students. This study used a multimethod approach to describe how bereavement and CG may impact medical students' educational experience and their perspectives on grief support and training. One hundred three medical students completed an online survey with quantitative and qualitative methods. Seventy-three (71%) students reported experiencing bereavement, of which 12 (18%) screened positive for CG. Medical students who screened positive for CG reported significantly more emotional and behavioral challenges (M = 3.58 [SD = 2.64]) compared to medical students without CG (M = 0.93 [SD = 1.58], p < .001). Qualitative analyses revealed that bereaved and nonbereaved students wanted more grief education and bereavement support from medical institutions. Therefore, it is crucial for medical institutions, to acknowledge that grief and bereavement may impact students' performance due to multifactorial causes.

Adaptation and Pilot Study of a Behavioral Intervention Targeting Morning Activation Deficits in Dementia Caregivers: Scheduling Activity and Monitoring Mornings (SAMM).

OBJECTIVES: Morning activation deficits (MADs) correlate with depression symptom persistence in older dementia caregivers. To clarify the potential of MADs as a target for depression interventions, we aimed to: 1) adapt an existing behavioral activation program, Engage therapy, to target mornings; and 2) evaluate effects on self-reported MADs and depression symptoms. METHODS: While trialing the 9-week Engage adaption (targeting mornings) in six older dementia caregivers, we incorporated feedback and finalized an adapted program called Scheduling Activity and Monitoring Mornings (SAMM). We delivered the SAMM protocol to 13 dementia caregivers (all female; mean age = 69, standard deviation = 7). We report modifications made/rationale, as well as changes in subjective MADs (relevant items from the Composite Scale of Morningness) and depression symptoms (Patient Health Questionnaire - 9). RESULTS: Using caregiver and expert input, we adapted the protocol to: include educational materials/content describing the potential relationship between morning inactivity and depression; target activity scheduling within 2 hours of awakening (preferably earlier); and focus only on the main components of morning activity scheduling, planning, and monitoring. This program was associated with decreases in subjective MADs averaging 29% at week 4, 52% at week 6, and 57% by week 9 (all p's <0.005). Initial depression symptoms were significantly reduced, by 62%, at week 9. CONCLUSIONS: These preliminary findings suggest that subjective MADs can be modified pragmatically, and that doing so may have antidepressant effects. A controlled trial with measures of the putative mechanism is needed to clarify whether, and if so how, targeting MAD with SAMM causally perturbs depression's mechanisms.

Predicting Medication Nonadherence in Older Adults With Difficult-to-Treat Depression in the IRL-GRey Randomized Controlled Trial.

OBJECTIVE: Nonadherence to antidepressants interferes with optimal treatment of late-life depression. This analysis examines clinical and treatment factors predicting medication nonadherence in difficult-to-treat late-life depression. METHODS: Secondary analysis of data from a clinical trial of antidepressant pharmacotherapy for Major Depressive Disorder in 468 adults aged 60+ years. All participants received venlafaxine XR for 12 weeks. Nonremitters were randomized to augmentation with either aripiprazole or placebo for 12 additional weeks. Medication adherence was assessed 14 times over 24 weeks. The analyses examined sociodemographic, clinical, and treatment factors that may predict antidepressant nonadherence during early (weeks 1-6), late (weeks 7-12), and augmentation (weeks 13--24) treatment. RESULTS: Poor cognitive function and early response were predictive of early nonadherence. Poor cognitive function and prior nonadherence were predictive of late nonadherence. Living alone was associated with nonadherence both late and during augmentation treatment. CONCLUSION: Future studies should consider the role of early response and cognitive function to improve antidepressant adherence, particularly among older adults who live alone.

Pediatric Sleep Disturbances and Symptoms of Depression in Older Adults.

We investigated the association between retrospectively reported sleep disturbances during childhood and adolescence and current symptoms of depression and anxiety in older adults. Participants included 116 older adults (M age = 68 years [SD = 6.4 years]) who completed a battery of sleep and psychological assessments. We tested two multivariate regression models using age, sex, race, physical illness burden, insomnia status, and pediatric sleep disturbances as correlates of depressive symptoms and anxiety symptoms. Pediatric sleep disturbances were significantly associated with greater depressive symptomatology (ß = 0.247, p = .010), independent of current insomnia status. Medium effect sizes were reported. Our results suggest that pediatric sleep disturbances may be a biobehavioral signal for the development of poor emotional health across the lifespan. Future research should identify critical windows of development when sleep disturbances might be most impactful on emotional health trajectories.

Subjective Sleep Quality and Trajectories of Interleukin-6 in Older Adults.

BACKGROUND: We aimed to identify trajectories of inflammation in older adults at elevated risk for syndromal depression and anxiety and to determine whether baseline physical, cognitive, and psychosocial factors could distinguish 15-month longitudinal trajectories. METHODS: Older adults (N = 195, mean age (±SD) = 74.4 years (9.0) participating in three depression and anxiety prevention protocols completed a comprehensive battery of psychosocial assessments and provided blood samples for analysis of interleukin-6 (IL-6) every 3 months over a maximum of 15 months. Group-based trajectory modeling identified trajectories. Adjusted logistic regression examined associations between baseline factors and trajectory groups. RESULTS: Two 15-month trajectories were identified: stable lower IL-6 levels (84%; mean (±SD) = 3.2 (2.1) pg/mL); and consistently higher IL-6 levels (16%; mean = 9.5 (7.4) pg/mL). Poor sleep quality predicted consistently higher levels of IL-6 (OR = 1.9, 95% CI = 1.03-3.55). CONCLUSION: Poor sleep quality may represent a therapeutic target to reduce inflammation.

Cancer Bereavement and Depression Symptoms in Older Spouses: The Possible Modifying Role of the Circadian Rest-Activity Rhythm.

OBJECTIVES: This study examines the associations of cancer death and aspects of the 24-h circadian rest-activity rhythm (RAR) on depression symptoms in older spouses. METHODS: Participants included 46 adults aged 60-94 years (M = 73 years) who experienced the death of a spouse. We tested a multivariate model using cancer death (vs. non-cancer death) and RAR variables as correlates of depression symptoms while controlling for age, sex, physical illness burden, and preparedness for death. We also present a case example to describe the behavioral activity patterns of a participant bereaved by cancer. RESULTS: Cancer death was associated with elevated levels of depression symptoms. However, the timing of the RAR moderated this association. Cancer bereavement was associated with depression symptoms when participants "settled-down" after 11:00 PM. The case example illustrates how intrusive thoughts about death quality impacts a widower's drive to stay busy with daily activities. CONCLUSIONS: Settling down earlier in the evening is important for older spouses bereaved by cancer, in terms of fewer symptoms of depression. CLINICAL IMPLICATIONS: Objectively specifying the activity patterns of older spouses bereaved by cancer is a promising avenue for interventions that aim to reduce depression symptoms.

Cross-Cultural Experiences of Hospice and Palliative Care Services: A Thematic Analysis.

Significant disparity exists among non-Western and minority individuals in hospice and palliative care services. A cross-cultural approach that addresses the needs of these patients would decrease this disparity. This study reviews the literature on the experiences of patients from non-Western and minority cultural backgrounds in hospice and palliative care services to inform clinical practice by Western providers. The PubMed database was searched for qualitative studies on patient and family member experiences of end-of-life services among minority or non-Western cultural groups. Eighteen articles met eligibility criteria. The major themes identified include the following: communication and the flow of information, perceptions of hospice and palliative care, and compatibility with cultural beliefs. This review demonstrates similar themes across many non-Western and minority cultures when interacting with hospice and palliative care services. These findings emphasize the importance of a cross-cultural approach in a palliative care and hospice setting.

Digital Monitoring of Sleep, Meals, and Physical Activity for Reducing Depression in Older Spousally-Bereaved Adults: A Pilot Randomized Controlled Trial.

OBJECTIVES: To evaluate the feasibility and acceptability of a behavioral intervention and explore its impact on depression symptom burden among older spousally-bereaved adults. METHODS: Participants were age ≥60 years, bereaved ≤8 months, and at high risk for depression. Participants were randomized to 12 weeks of digital monitoring of sleep, meals, and physical activity; digital monitoring plus health coaching; or enhanced usual care and followed for 9 months for new-episode depression. RESULTS: We enrolled 57 participants, 85% of eligible adults and 38% of all adults screened. We observed high levels of adherence in both digital monitoring (90%) and health coaching (92%); 88% of participants were retained. In linear mixed-effects models, depression symptoms significantly decreased, but the interaction between time and intervention was not significant. CONCLUSION: A behavioral intervention that uses both digital monitoring and motivational health coaching is feasible and acceptable to older bereaved adults.

White Matter Integrity Underlying Depressive Symptoms in Dementia Caregivers.

OBJECTIVE: We sought to determine whether the aspects of white matter connectivity implicated in major depression also relate to mild depressive symptoms in family dementia caregivers (dCGs). METHODS: Forty-one dCGs (average age=69 years, standard deviation=6.4) underwent a 7 Tesla 64-direction (12-minute) diffusion-weighted imaging sequence. We compared the fractional anisotropy (FA) of 11 white matter features between dCGs with (n=20) and without (n=21) depressive symptoms (Patient Health Questionnaire-9 scores ≥5). RESULTS: Caregivers reporting depression symptoms had lower FA in tracts connecting to the posterior cingulate cortex (Cohen's d = -0.9) and connecting dorsolateral prefrontal with rostral cingulate regions (Cohen's d = -1.2). CONCLUSIONS: Posterior cingulate and dorsolateral prefrontal-to-rostral cingulate white matter, implicated in prior studies of major depression, appear relevant to mild depression in dCGs.

Opioid Exposure Negatively Affects Antidepressant Response to Venlafaxine in Older Adults with Chronic Low Back Pain and Depression.

OBJECTIVE: Serotonin norepinephrine reuptake inhibitors (SNRIs) are commonly co-prescribed with opioids for chronic pain. The purpose of this study was to describe pain and mood response to venlafaxine among older adults with chronic low back pain (CLBP) and depression relative to opioid exposure. DESIGN: Secondary analyses were collected from a randomized clinical trial testing a stepped-care approach to comorbid pain and depression in older patients: the Addressing Depression and Pain Together study (ADAPT: 2010-2016). SETTING: University-based late-life mental health research clinic. SUBJECTS: Two hundred twenty-seven adults aged 65+ years with CLBP and depression. METHODS: Participants received six weeks of lower-dose venlafaxine (≤150 mg/d). Pain and depression were measured each week. Response for both pain and depression at the end of six weeks was defined by a ≥30% improvement on a 0-20 numeric rating scale for low back pain and a Patient Health Questionnaire-9 score ≤5. Opioid exposure was analyzed as prescribed (yes or no) and by morphine equivalent dosing (MED). RESULTS: Patients co-prescribed an opioid were less likely to report a pain response to venlafaxine. MED was negatively correlated with pain response. Depression response was not impacted. CONCLUSIONS: Opioids are negatively associated with older adults' early analgesic response to lower-dose venlafaxine. These findings suggest that clinicians may wish to consider either nonopioid or alternative antidepressant approaches to pain management in these complex patients. It is reassuring that opioids do not prevent depression response. Future research should examine both longer duration of treatment and a wider range of doses.

Safety Planning to Manage Suicide Risk with Older Adults: Case Examples and Recommendations.

Adults age 65 and older have high rates of suicide, despite recent efforts to reduce the suicide rate in this population. One suicide prevention strategy with burgeoning empirical support is safety planning; however, there is a lack of information and resources on safety planning for older adults to support uptake of this evidence-based practice in clinical settings where older adults are commonly seen. Safety plans can address risk factors for suicide in older adults, including social isolation, physical illness, functional limitations, and use of highly lethal means. Safety plans also promote relevant protective factors, including increasing use of coping strategies, social support, and help-seeking. Clinicians may encounter challenges and barriers to safety planning with older adults. This paper describes a collaborative, creative approach to safety planning that is relevant and useful for this vulnerable population. Using two case examples, we illustrate how to engage older adults in safety planning, including ways to minimize barriers associated with the aging process.

Feeling Relieved After the Death of a Family Member With Dementia: Associations With Postbereavement Adjustment.

OBJECTIVE: After an extended period of caregiving, the death of a family member with dementia can provide a sense of relief to individuals because caregiving has ended and their loved one is no longer suffering. Little is known about predeath factors associated with feeling relieved after the death of a family member with dementia. This study examined 1) predeath factors associated with caregiver (CG) relief; and 2) whether CG relief is associated with postbereavement adjustment, namely complicated grief and depression symptoms. METHODS: Participants were bereaved CGs aged 28-90 years old drawn from the Resources for Enhancing Alzheimer's Caregiver Health (REACH) (N = 223) and Family Caregiver Transition Support (FaCTS) (N = 89) studies. In each sample, demographics were assessed at baseline, and CG relief was assessed at the first follow-up assessment after death. Each study administered a similar bereavement battery to CGs following the death of their care recipients (CRs). RESULTS: CGs of late-stage dementia patients (FaCTS) reported more relief compared with CGs of early- to midstage dementia patients (REACH). CGs were more likely to experience relief if they were prepared for their CR's death and if they perceived their CR's death to be a relief to the CR. A multivariate regression model showed that greater CG relief was associated with less complicated grief postbereavement. CG relief was not significantly associated with depression symptoms. CONCLUSION: We show prospectively that the caregiving experience impacts feelings of relief, and that feeling relieved facilitates postbereavement adjustment by lessening symptoms of complicated grief.

Depression Agency-Based Collaborative: Effect of Problem-Solving Therapy on Risk of Common Mental Disorders in Older Adults With Home Care Needs.

BACKGROUND: Interventions to prevent depression in older adults have mainly focused on young-old ambulatory adults, not on the old-old with disabilities who receive supportive services in their homes. OBJECTIVE: The Depression Agency-Based Collaborative (Dep-ABC) is a single-blind pilot randomized controlled trial assessing the effect of an intervention-development strategy using problem-solving therapy (PST) on the risk of common mental health disorders in this vulnerable population. METHODS: The intervention involved six to eight sessions of PST over 12 weeks. Participants were followed up to 12 months postintervention. RESULTS: Dep-ABC randomized 104 participants-68.4% of eligible and 17.5% of all older adults screened. The proportion of participants with incident major depressive disorder or generalized anxiety disorder was 11.4% in PST and 14.3% in the enhanced usual care control arm. A test of the interaction between time and intervention for anxiety symptoms favored the PST arm (p = 0.04). CONCLUSION: PST did not lower the risk of incident common mental illness but did lower anxiety symptom burden. Apart from low power, the effects of PST may have been blunted by referral for medical and aging services in the enhanced usual care group.

Restorative activities among bereaved caregivers of nursing home patients.

This prospective study examined predictors and correlates of restorative activities in recently bereaved caregivers and their relation to post-bereavement adjustment, namely complicated grief. Participants included 89 caregivers (CGs) age 32-87 (M age - 63 years) whose care recipients recently died in a long-term care facility (M time since loss = 107 days). Our findings show that being prepared prior to death enables CGs the opportunity to engage in restorative activities post death. Restorative activities partially mediated the relationship between preparedness prior to death and complicated grief, but this association was attenuated in multivariable models. It is possible that being prepared prior to death allows CGs to engage in restorative activities post-death, which in turn decreases complicated grief. More research is needed in diverse populations of CGs to determine how restorative activities may impact post-bereavement adjustment.

Treatment Considerations for Depression Research in Older Married Couples: A Dyadic Case Study.

OBJECTIVE: Critical gaps remain in understanding optimal approaches to intervening with older couples. The focus of this report is to describe the pros and cons of incorporating spousal dyads into depression-prevention research. METHODS: In an intervention development study, the authors administered problem-solving therapy (PST) dyadically to participants with mild cognitive impairment (MCI) and their caregivers. Dyads worked with the same interventionist in the same therapy session. The dyadic PST (highlighted in a case example of a husband with MCI and his wife/support person) and the potential feasibility of the program are described. RESULTS: The authors found that the wife of the individual with MCI could be trained as a PST coach to help her husband learn and use problem-solving skills. A decrease in depressive symptom severity was observed for the individual with MCI, which was sustained over 12 months of follow-up. Neither the husband nor wife experienced an incident episode of major depression over the course of the study. CONCLUSION: Dyadic interventions need to be further developed in geriatric psychiatry; proven methods such as PST can be modified to include patients' support persons. Recommendations are offered for developing randomized controlled trials that aim to recruit dyads and prevent depression in at-risk older married couples.

Measuring Participant Effort in a Depression Prevention Trial: Who Engages in Problem-Solving Therapy?

OBJECTIVE: To determine the acceptability of clinical interventions for depression prevention, identification of clinical characteristics associated with intervention engagement is needed. The purpose of this study is to describe levels and correlates of participant engagement in Problem Solving Therapy (PST) in adults 60 and older with subthreshold depression. METHODS: As part of a clinical trial to prevent depression among older adults with subthreshold depression, participants who were randomized to receive PST completed 6-8 sessions in which they learned skills to solve self-selected problems that were contributing to stress and reduced quality of life. To measure participants' engagement with PST, interventionists completed 3 scales that rated participants' level of participation in problem solving activities, understanding of the multistep process of PST, and between-session homework effort. Using logistic regression, we examined whether physical health, level of cognitive function, gait speed, and disability served as correlates of engagement in the PST intervention. RESULTS: Gait speed, a measure of physical and cognitive health, was significantly associated with engagement in PST. Participants who walked faster were more likely to engage with PST compared to participants who walked more slowly. No other baseline variables were significant correlates. CONCLUSIONS: Older adults who walk more slowly may need alternative delivery methods to fully engage in PST. Gait speed reflects physical and cognitive health, and predicts frailty, disability, and psychomotor speed slowing. For these reasons, gait speed may be a marker for factors that will serve to predict poorer engagement in psychosocial interventions like PST.
