Bakas照顾结果量表评估脑卒中主要居家照顾者负荷的适用性研究

Applicability of Bakes Caregiving Outcom Scale in the study of primary family caregivers＇burden of stroke survivors

目的探讨Bakas照顾结果量表评估脑卒中居家照顾者负荷的适用性。方法用Bakas照顾结果量表对上海市区180名脑卒中主要居家照顾者进行问卷调查，从内部一致性、结构效度和效标关联效度对量表进行适用性评估。结果各条目与Bakas照顾结果量表总分的相关系数0．408-0．725（P〈0．01）；量表总的Cronbach’s α仅值为0．877；用因子分析检验量表的结构效度，提取3个公因子累积贡献率达到60．93％，每个条目的因子负荷0．510-0．875；以负荷可视化标尺作为标准，Bakas照顾结果量表的效标关联系数为-0．461（P〈0．01）。结论Bakas照顾结果量表用于评估脑卒中居家照顾者负荷有较好的适用性。

Objective To investigate the applicability of Bakes Caregiving Outcom Scale（BCOS） in the study of primary family caregivers＇burden of stroke survivors. Methods The BCOS was used to investigate the 180 primary family caregivers of stroke survivors.The applicability of BCOS was evaluated by internal consistency,construct validity and criterion-related validity. Results The correlation coefficient be- tween the items and the total BCOS score was 0.408-0.725 （P 〈 0.01 ）.The total Cronbach＇s α was 0.877. Factor analysis used for examining the construct validity showed that 3 components were extracted and their accumulated contribution rate reached 60.93%.Factor loading of each item ranged from 0.510 to 0.875.The criterion-related validity was -0.461 by using self-rated burden asa criterion（P 〈 0.01 ）. Conclusions BCOS is applicable in the evaluation of the primary family caregivers＇ burden of stroke survivors.
