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.

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.

Comparison of Healthcare Utilization Between Informal Caregivers and Non-Caregivers: An Analysis of the Health Information National Trends Survey.

Objective: The demands of providing unpaid care for someone with a disabling health condition (i.e., informal caregiving) can limit attention to one's own health needs. Using a nationally representative survey, this study examines whether caregivers report different healthcare utilization relative to non-caregivers. Method: Participants in the Health Information National Trends Survey 5, Cycle 1 reported whether they provided unpaid care and healthcare utilization outcomes. Logistic regressions and chi-square tests with jackknife variance estimation were used. Results: Caregivers (N = 391) did not differ from non-caregivers (N = 2,894) in time since routine checkup or number of healthcare appointments in the past year (p values > .25). Among caregivers, number of healthcare appointments differed according to caregivers' relationship to the care recipient (p = .04). Discussion: Findings suggest that informal caregivers access routine healthcare at a frequency similar to non-caregivers. Further research should determine whether this utilization is optimal, or whether increased utilization during caregiving might help attenuate caregivers' longer term morbidity.

Effects of caregiving status and changes in depressive symptoms on development of physical morbidity among long-term cancer caregivers.

OBJECTIVE: Cancer caregiving burden is known to vary across the survivorship trajectory and has been linked with caregivers' subsequent health impairment. Little is known, however, regarding how risk factors during long-term survivorship relate to vulnerability to caregivers' health during that period. This study examined effects of caregiving status and depressive symptoms on development of physical morbidity by 5 years postdiagnosis. METHOD: Family caregivers (N = 491; Mage = 55.78) completed surveys at 2 (Time 1 [T1]) and 5 years (T2) after their care recipients' cancer diagnosis. Demographic and caregiving context variables known to affect caregivers' health were assessed at T1. Self-reported depressive symptoms and a list of physical morbid conditions were assessed at T1 and T2. Caregiving status (former, current, or bereaved) was assessed at T2. RESULTS: Hierarchical negative binomial regression revealed that current caregivers at T2 (p = .02), but not those bereaved by T2 (p = .32), developed more physical morbid conditions between T1 and T2 compared with former caregivers, controlling for other variables. Independently, caregivers reporting either newly emerging or chronically elevated depressive symptoms at T2 (ps < .03), but not those whose symptoms remitted at T2 (p = .61), showed greater development of physical morbidity than did those reporting minimal depressive symptoms at both T1 and T2. CONCLUSIONS: Results highlight the roles of long-term caregiving demands and depressive symptoms in cancer caregivers' premature physical health decline. Clinical attention through the long-term survivorship trajectory should be emphasized for caregivers of patients with recurrent or prolonged illness and to address caregivers' elevated depressive symptoms.
