背景资料。中风幸存者的家庭照顾者由于提供护理而经历了各种负面的社会、情感和健康相关的结果。目的：对修订的15个条目的巴卡斯护理结果量表(BCOS)进行心理测量学测试，该量表专门测量由于提供护理而导致的生活变化。方法：对修订后的15项BCOS进行心理测量，对147名卒中幸存者的家庭照顾者在卒中后约4个月进行心理测量，以确定条目的质量、内部一致性信度、重测信度、结构效度和效标相关效度。大多数照顾者是女性(78.9%)、白人(68.0%)或非裔美国人(29.9%)，配偶(60.1%)或成年子女(31.3%)。结果：提供了令人满意的内部一致性证据(阿尔法=90)和两周重测可靠性(组内系数[ICC]=66；95%可信区间[CI]=0.42-0.81)，条目与总条目的相关范围为0.41至0.74。各指标的验证性因子分析支持单维度，具有较好的匹配性。通过分层多元回归，概念模型中的结构可以解释36%的BCOs方差[F(11,132)=6.72，p<；.001]。标准相关效度得到了36项简表(SF-36)一般健康子量表(r=.32，p&t；.001)和衡量照顾者生活总体变化的标准变量(r=.67，p<；.001)的相关性的支持。讨论：修订的15项BCOS在中风幸存者的家庭照顾者中具有令人满意的信度和效度。BCOS在研究中是一项有价值的衡量标准，可用于确定护理干预的优先领域，旨在改善照顾者的结果。
Background. Family caregivers of stroke survivors experience a variety of negative social, emotional, and health-related outcomes as a result of providing care.Objectives: To psychometrically test the revised 15 item Bakas Caregiving Outcomes Scale (BCOS) measuring life changes specifically resulting from providing care. The original 10-item BCOS was improved by adding five items addressing financial well-being, level of energy, role functioning, physical functioning, and general health.Methods: Psychometric testing of the revised 15-item BCOS using a sample of 147 family caregivers of stroke survivors approximately 4 months after stroke was conducted to determine the quality of the items, internal consistency reliability, test-retest reliability, construct validity, and criterion-related validity. Most caregivers were women (78.9%), White (68.0%) or African American (29.9%), and either spouses (60.1%) or adult children (31.3%).Results: Satisfactory evidence of internal consistency (alpha = 90) and 2-week test-retest reliability (intraclass coefficient [ICC] = 66; 95% confidence interval [Cl] = 0.42-0.81) was provided, with item-to-total correlations ranging from .41 to .74. Unidimensionality was supported by confirmatory factor analysis with indices, indicating a good fit. Using hierarchical multiple regression, 36% of the BCOS variance was explained by constructs in the conceptual model [F(11, 132) = 6.72, p < .001]. Criterion-related validity was supported by correlations with the 36-item Short Form (SF-36) General Health Subscale (r = .32, p < .001) and a criterion variable measuring how caregivers lives had changed overall (r = .67, p < .001).Discussion: The revised 15-item BCOS has evidence of satisfactory reliability and validity in family caregivers of stroke survivors. The BCOS is a valuable measure in research and can be used to identify priority areas for nursing interventions designed to improve caregivers' outcomes.
