Timed Activity to Minimize Sleep Disturbance in People With Cognitive Impairment

Background and Objectives

Sleep disturbances occur in >60% of persons living with cognitive impairment, affecting their quality of life (QOL). Regulating the sleep-wake cycle through engaging cognitive, physical, and sensory-based activities delivered at strategic times may reduce sleep disturbances and be a feasible nonpharmacological treatment for sleep problems. The objective of this trial was to test the efficacy of a timed-activity intervention in improving QOL and sleep disturbances in persons living with cognitive impairment.

Research Design and Method

Randomized 2-group parallel design involving 209 dyads of community-residing persons living with cognitive impairment and care partners. Dyads were randomly assigned (1:1) to 1-hr home activity sessions administered weekly in the morning, afternoon, or evening over 4 weeks (the Healthy Patterns Sleep Program), or to an attention-control condition consisting of sleep hygiene training plus education on home safety and health promotion. QOL, objective and subjective sleep quality, and neuropsychiatric symptoms were assessed at baseline and 4 weeks later.

Results

QOL was significantly improved in the intervention group compared to control (p = .0491). There were no significant effects on objective or subjective sleep or neuropsychiatric symptoms. In a subgroup analysis, subjective sleep as measured by the PROMIS (Patient Reported Outcomes Measurement Information System) Sleep-Related Impairment survey was significantly improved in the intervention group compared to the control group for individuals with symptoms of depression (p = .015) or poor observed sleep at baseline (p = .005).

Discussion and Implications

The Healthy Patterns Intervention may benefit QOL for persons living with cognitive impairment and those with poor subjective sleep. A longer dose may be necessary to elicit improvement in actigraphically measured sleep-wake activity.

Adult day services and dementia caregivers' daily affect: the role of distress response to behavioral and psychological symptoms of dementia

Adult day services (ADS) provide respite for dementia caregivers and directly reduce exposure to behavioral and psychological symptoms of dementia (BPSD). This study examines the psycho-behavioral mechanism on how daily ADS use may benefit caregivers' daily affect through its impact on the distress associated with BPSD stressor exposure. The sample consists of dementia caregivers (N = 173) who participated in an ADS intervention across 8 days. Multilevel structural equation modeling was conducted to examine the within- and between-person mediating effects of BPSD distress on the direct associations between daily ADS use and daily negative and positive affect. ADS days were associated with lower daily negative affect and higher daily positive affect; the significant within-person effect of ADS use on daily affect was mediated by daily BPSD distress. Findings highlight the association between daily ADS use and caregiver affective well-being. This understanding is important for designing respite and other interventions to help dementia caregivers manage the daily stress of caregiving.

Financial Strain, Employment, and Role Captivity and Overload Over Time Among Dementia Family Caregivers

BACKGROUND AND OBJECTIVES

This study examined how financial strain and changes in employment status affect subjective stressors over 12 months in 184 family caregivers of individuals with dementia.

RESEARCH DESIGN AND METHODS

Subjective stressors of role overload and role captivity, and employment status were measured at baseline, 6-, and 12-months. Self-reports on financial strain were measured at baseline only. Caregivers were categorized into 3 groups based on changes in their employment status during the study over 12 months: (a) who were never employed, (b) who experienced some sort of employment status change, either going from employment to unemployment or vice versa, and (c) who were always employed. Growth curve analyses were conducted to examine within-person changes in role overload and role captivity, and associations with employment and financial strain.

RESULTS

Caregivers with greater financial strain at baseline had higher levels of role overload and increasing role captivity over time. Caregivers who experienced a caregiving transition and had low financial strain at baseline showed greater decrease in role captivity over 12 months. Although caregivers who were consistently unemployed reported lower levels of role overload, they also showed steeper increase over time than those who were consistently employed.

DISCUSSION AND IMPLICATIONS

Caregivers' perceptions of financial strain add to the long-term stress of the caregiving role. Changes in caregivers' employment status may have complex associations with their feelings of stress over time.
