Development and testing of a scale to measure caregiving load in caregivers of cancer patients in Taiwan, the care task scale-cancer.
The purpose of this study was to develop and test an instrument to measure care tasks for Taiwanese spouse caregivers of cancer patients. A 37-item Care Task Scale-Cancer (CTS-C) was developed using both quantitative and qualitative approaches. The reliability and validity of the CTS-C was tested on a convenience sample of 150 spouse caregivers caring for patients with breast cancer, head neck cancer, or esophageal cancer. Factor analysis showed that the CTS-C had 4 underlying factors (subscales): (1) accompany patient and monitor care (12 items), (2) substitutive care for social and general affairs (12 items), (3) communication and emotional care (9 items), and (4) mobility maintenance care (4 items). These 4 factors explained 52.3% of the total variance. Cronbach alpha coefficients for these 4 subscales ranged from .83 to .88. Test-retest coefficients (r) ranged from 0.92 to 0.94. The construct validity of this scale was supported by demonstrating a negative correlation between CTS-C scores (demand, difficulty, and caregiving load) and functional performance status, and positive correlations with caregiver burden and symptom distress. These results showed satisfactory validity and reliability for the CTS-C.
