BackgroundProstate cancer is the most frequent neoplasm in Mexican men, the research literature contains few studies that address prostate cancer patients and quality of life in Mexico.ObjectiveTo validate the Functional Assessment Cancer therapy (FACT-P) scale.Method201 males 49 to 90 years of age, at any clinical stage of prostate cancer, under treatment or follow-up participated. It's a non-experimental cross-sectional study. Patients were evaluated through the FACT-P jointly with the European Organization for Research and Treatment of Cancer Quality of Life and Hospital Anxiety and Depression Scale. Exploratory analysis examined the factorial structure, and confirmatory analysis to evaluate the adjustment of the exploratory model to the data.ResultsA four-factor model that explained 64.65% of the variance, Cronbach's alpha 0.79, and correlations were statistically significant, Pearson's r of 0.146-0.716, p < 0.01 and p < 0.05. Analyses also distinguished metastatic patients from non-metastatic ones. The main indices of the confirmatory model were satisfactory for the adjustment of data and showed an estimate error close to zero.ConclusionsThis Mexican version of FACT-P showed reliability and validity comparable to the original one.Copyright: © 2020 Permanyer.
