Mexican validation of the QLQ-INFO25 instrument to measure satisfaction
with the received information in patients with gastrointestinal
carcinoma
Abstract
Background: The information received by patients with cancer and the
consequent satisfaction are main components of the evaluation of quality
of care. We aim to validate the Mexican-Spanish version of the
QLQ-INFO25 in patients with gastrointestinal cancer. Methods: Patients
included responded the QLQ-INFO25 instrument at a cancer center. The
usual psychometric tests were performed. Results: 70 female and 66 males
were included (mean age 56.2); 111 were colorectal and 25
gastroesophageal cancer. Questionnaire compliance rates were high and
the instrument was well accepted. No missing values were found.
Convergent item correlation was 0.008 to 0.768 and divergent item
correlation was from 0.014 to 0.662. Cronbach’s α coefficients of
multi-item scales were >0.7 (range, 0.655–0.905). Four
scales distinguished among esophagogastric or colorectal cancer, and
four scales were associated with overall survival. Conclusion: The
Mexican-Spanish version of the questionnaire is reliable and valid to be
used in clinical trials.
