Abstract

Objective: To examine the validity of the Comfort Assessment Breast Cancer Instrument (CABCI) and compare the results of CABCI with that of salivary cortisol examination. Method: For assessing construct validity, second-order confirmatory factor analysis (CFA) was performed with M-Plus, and for assessing criterion validity, salivary cortisol examination was performed. Results: The results of CFA indicated that the model was a good fit (X2 = 283.654, df = 10, p = 0.000, RMSEA = 0.000, p RMSEA ≤0.05 = 0.797, CFI = 1.000), and the 33 items of CABCI were found to be statistically significant (t > 1.96; p <.05). A significant correlation was found between patient discomfort and salivary cortisol level (r = 0.416; p =.016). Conclusion: The study proves the construct and criterion validity of CABCI, and therefore indicates its validity for predicting discomfort in breast cancer patients.
