The primary aim of this study was to examine the pattern of associations among PD patient and caregiver sleep problems, caregiver burden, and caregiver life satisfaction. A secondary aim was to assess whether the pattern of associations differed between Mexican and U.S. caregivers. Analyses were performed on data obtained from 253 caregivers (M age = 59.92). A composite score was produced for caregiver and patient sleep problems. The Zarit Burden Interview and Satisfaction with Life Scale measured caregiver burden and life satisfaction, respectively. A structural equation model with an invariance design was developed to examine and compare the pattern of associations. The model was generally invariant across U.S. and Mexican caregivers. Three significant indirect effects were found: caregiver sleep problems were negatively associated with life satisfaction via caregiver burden (p = 0.003); PD patient sleep problems were positively related to caregiver burden via caregiver sleep problems (p = 0.005) and life satisfaction via caregiver burden and caregiver sleep problems (p = 0.002). PD patient sleep problems were associated with caregiver sleep problems, leading to increased burden in caregivers and poorer life satisfaction. The findings highlight a potential opportunity for empirically supported sleep interventions. Parkinson's disease is a progressive neurological condition that impacts patient and caregiver quality of life. Patient sleep problems contribute to greater caregiver burden, sleep problems, and reduced life satisfaction. The findings suggest patient and caregiver sleep may be a worthwhile target for intervention in order to reduce risk of caregiver burden and improve life satisfaction. [ABSTRACT FROM AUTHOR]

Objective: The population of individuals with Parkinson's disease (PD) is growing in Mexico and the United States, and there is an increasing need for family members to provide caregiving. This study examined the connections between family dynamics and coping, or sense of coherence, among PD caregivers in Mexico (n = 148) and the United States (n = 105). Methods: Caregivers completed measures of family dynamics and sense of coherence across indices of comprehensibility, manageability, and meaningfulness. Results: Although caregivers in Mexico and the United States had similar levels of sense of coherence and family dynamics reflecting strengths/adaptability and being overwhelmed with difficulties, caregivers in Mexico had worse disrupted communication. Family dynamics explained: 24.2% of the variance in caregiver comprehensibility in the United States and 17.5% in Mexico; 34.1% in manageability in the United States and 23.5% in Mexico; and 22.6% in meaningfulness in the United States and 22.7% in Mexico (all Ps < 0.001). In both Mexico and the United States, family strengths/adaptability uniquely predicted caregiver comprehensibility, manageability, and meaningfulness. Being overwhelmed with difficulties uniquely predicted comprehensibility in Mexico and manageability and meaningfulness in the United States. Conclusion: The development of family‐systems interventions for PD caregivers to improve family strengths/adaptability and help families deal with difficulties may increase caregiver coping.

BACKGROUND/OBJECTIVE: Given the growing population of individuals with Parkinson's disease (PD) worldwide and the growing need for family members to take on a caregiving role, it is critical that cross-cultural differences be examined in order to better meet the needs of PD caregivers. The purpose of this study was to examine the connections between the unmet needs and mental health of PD caregivers differentially in Mexico and the United States. METHODS: In Parkinson's clinics at public, academic medical centers, PD caregivers from Mexico (n = 148) and the United States (n = 105) completed measures of unmet family needs and mental health. RESULTS: Caregivers in the United States had higher unmet needs for emotional support and for a community support network than caregivers in Mexico, although caregivers at the two sites had comparable levels of anxiety and depression. Unmet family needs explained 29.5% of the variance in caregiver anxiety in the United States (p < 0.001) but only 5.7% in Mexico (p = 0.209). Unmet family needs explained 30.4% of the variance in caregiver depression in the United States (p < 0.001) and 14.0% in Mexico (p = 0.001). In the United States, unmet needs for emotional support and for instrumental support uniquely predicted caregiver anxiety and depression, and in Mexico only the unmet need for instrumental support was a unique predictor. CONCLUSIONS: PD caregivers in the United States are at increased risk for poor emotional and community support, and these unmet needs channel directly into caregiver anxiety and depression. In Mexico, where caregivers have stronger emotional and community support, caregivers' unmet need for instrumental support generates anxiety and depression. Important targets for PD caregiver interventions may differ between Mexico and the United States. [ABSTRACT FROM AUTHOR]
