Predictors of psychological distress and sleep deprivation in caregivers of stroke survivors.

BACKGROUND

Caregivers for stroke survivors (CSS) suffer from long hours of care, limited support, and financial difficulties, which often affect their mental health.

OBJECTIVES

This study sought to determine the factors affecting psychological distress and sleep duration among CSS.

METHODS

We analyzed cross-sectional data from the 2013 Comprehensive Survey of the Living Conditions for Stroke Survivors and CSS. Linked data from 841 pairs of stroke survivors and CSS were extracted. Kessler's Psychological Distress scale (K6) was used to evaluate psychological distress. CSS who slept less than 5 hours per day were classified as having short sleep duration. Factors predictive of psychological distress and short sleep duration were evaluated using multivariable logistic regression analysis with the forward selection method.

RESULTS

The mean (SD) age of the CSS was 65.4 (12.5) years. A total of 5.6% of these caregivers presented with serious psychological distress, and 12.0% were sleep deprived. Serious psychological distress was associated with not having someone to consult with, having subjective symptoms within a few days, and having short sleep duration, while having their own houses reduced the risk of serious psychological distress. Furthermore, short sleep duration was associated with stroke survivors in long-term care levels 4 or 5, not having someone to consult with, participation in sponge baths as part of nursing care activities, and having serious psychological distress.

CONCLUSIONS

This nationwide survey identified several risk factors for psychological stress and sleep deprivation among CSS and suggests the need for multidimensional approaches to reduce their distress.
