- Abstract
Background and Purpose: The purpose of this secondary analysis was to examine the reliability and validity of the Patient Assessment of Own Functioning Inventory (PAOFI) in postmenopausal women with early-stage breast cancer before adjuvant therapy. Methods: Data from 259 postmenopausal women with early-stage breast cancer before adjuvant therapy were analyzed. Exploratory factor analysis was used to uncover the PAOFTs underlying factor structure and reliability coefficients were computed for each subscale. Results: 5 factors measuring perceived cognitive functioning had eigenvalues >1 and accounted for 54% of the extracted variance. Subscale reliability coefficients ranged from .572 to .883. Conclusions: Psychometric evaluation of the PAOFI provided evidence of reliability and construct validity in this population. Additional studies are needed to confirm the 5-factor structure.
