This longitudinal study explored changes in perceived burden among Taiwanese family caregivers (n=77) from nursing home placement of an elder to four months postadmission. Higher burden at placement was related to the level of dependence of the care recipients (p=0.004), or caregiver's poor health (p<0.01). After nursing home placement for four months, global burden decreased (p<0.01) contributed primarily by lessened burden in three sub-scales: lack of family support, impact of schedule and impact of health. Burden scores on caregiver esteem and impact of finances were not decreased after placement. Duration of caregiving was the only demographic factor predicting change in global burden (p<0.001). Changes in impact on finances, and impact on health were, respectively, predicted by the perceived health (p=0.005), and religious preference (p=0.01). These results provide valuable information to healthcare providers for an understanding of the changes of caregiving burden after nursing home placement and the correlates of these changes, which may help devise an appropriate policy for alleviating the caregiver's burden.
