Background and Purpose. Enhancing quality of life of family caregivers of heart failure patients is a transitional care issue for current directions in health care reform. While several quality of life measures exist, they are often too generic to capture the unique experience of this population. The purpose of this study was to psychometrically test the Heart Failure Caregiver Quality of Life Scale (HFCQL) that measures physical, psychological, social, and spiritual quality of life outcomes. Subjects and Methods. Psychometric testing of the HFCQL with a sample of 100 heart failure family caregivers was conducted using item analysis, Cronbach's alpha, intraclass correlation, factor analysis, and hierarchical multiple regression guided by a conceptual model. Caregivers were predominately female (89%), Caucasian (73%), and either spouses (62%) or adult children (26%). Results. Evidence of internal consistency reliability (alpha=.89) was provided for the HFCQL, with item-total correlations of .39 to .74. Two week test-retest reliability was supported by an ICC of .91. Using a one-factor solution and principal axis factoring, loadings ranged from .31 to .78 with 41% of the variance explained by the first factor (Eigen=6.5). With hierarchical multiple regression, 56% of the HFCQL variance was explained by model constructs [F(8,91)=16.56, p<.001]. Criterion-related validity was supported by correlations with SF-36 General (r=.45, p<.001) and Mental (r=.59, p<.001) Health Subscales and Bakas Caregiving Outcomes Scale (r=.73, p<.001). Evidence of internal and test-retest reliability and construct and criterion validity was provided for physical, psychological, and social well-being subscales. Conclusions. The 16-item HFCQL is a brief, easy to administer instrument that has evidence of reliability and validity in heart failure family caregivers. Physical, psychological, and social well-being can be measured with 4-item subscales. The HFCQL could serve as a valuable measure in research, as well as an assessment tool to identify caregivers in need of intervention.
