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

Abstract

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 inves-tigate the 180 primary family caregivers of stroke survivors.The applicability of BCOS was evaluated by in-ternal 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 as a criterion(P ＜ 0.01 ). Conclusions BCOS is applicable in the evaluation of the primary family caregivers' burden of stroke survivors. Key words: Scale; Stroke; Caregiver; , Burden; Applicability
