Abstract: INTRODUCTION: Cancer patients may suffer negative consequences; however, they also report positive aspects of psychological adjustment, such as posttraumatic growth. One of the most widely used instruments for measuring this is the Posttraumatic Growth Inventory (PTGI). OBJECTIVES: Cross-cultural adaptation and Mexican validation of the PTGI-X in the palliative oncology population. METHODS: A prospective cross-sectional study was conducted in 2 phases: the first involved translation and cross-cultural adaptation (expert judgment/piloting), and the second involved validation of the scale. In the latter, the sample comprised 236 advanced-stage oncology patients, and the following analyses were performed: 1) items under the classical test theory, 2) discrimination and internal consistency indices, 3) confirmatory factor analysis, and 4) convergent and divergent validity. RESULTS: /df = 2.83), CFI = 0.93, TLI = 0.93, RMSEA = 0.088, and SRMR = 0.065. Bivariate correlations were employed, showing moderate positive associations between the scale factors (r = 0.60 and 0.79) and low-magnitude positive correlations between the factors of posttraumatic growth and perception of quality of life (r = 0.14 and 0.18). SIGNIFICANCE OF RESULTS: The PTGI-X-Mx showed satisfactory psychometric properties in patients with advanced oncological disease receiving palliative care.
