Spousal Caregivers of Coronary Artery Bypass Surgery Patients: Differences between Caregivers with Low vs. High Caregiving Demands.

The sample was small, so the findings need cautious interpretation. The study was cross-sectional, so it cannot show how caregiving demands, difficulty, communication, or mood change over time. Caregivers at different sites completed questionnaires at different times after discharge, which may have affected comparisons. The sample was mostly Caucasian women employed outside the home, so results may not apply to other caregiver groups. Some caregivers had missing item data, and missing data were not imputed. Caregivers who were depressed may have been less likely to consent or disclose symptoms, which could have limited detection of depression.

Do not conclude that higher caregiving demands cause greater difficulty or better communication. The study compared groups at a single time point, so it showed associations rather than effects, and depressive symptoms were minimal and did not differ.
