Abstract
Objectives The Schedule of Attitudes Toward Hastened Death (SAHD) has emerged as a valid and reliable tool to assess the wish to hasten death (WTHD) among patients diagnosed with advanced cancer; however, the instrument has never been culturally adapted and validated for patients in Mexico. This study sought to validate and abbreviate the SAHD tool for use among patients attending the Palliative Care Service of the Instituto Nacional de Cancerología in Mexico. Methods The SAHD was culturally adapted from a previously published validation in patients from Spain. Eligible patients included Spanish literate subjects treated as outpatients in the Palliative Care Service, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-3. Patients were asked to answer the Mexican version of SAHD (SAHD-Mx) instrument and the Brief Edinburgh Depression Scale (BEDS). Results A total of 225 patients were included in the study. Median positive response in the SAHD-Mx was 2 (range 0-18). Positive correlation was identified between the SAHD-Mx scale and ECOG performance status (r = 0.188, p = 0.005), as well as BEDS (r = 0.567, p < 0.001). SAHD-Mx displayed strong internal consistency (alpha = 0.85) and adequate reliability from test-retest phone interviews (r = 0.567, p < 0.001). Using the confirmatory factor analysis model, a factor was identified and the number of items was reduced to 6, including items 4, 5, 9, 10, 13, and 18. Significance of results The SAHD-Mx emerges as an adequate tool, with appropriate psychometric characteristics, for assessing WTHD among patients diagnosed with cancer undergoing palliative care in Mexico.. © The Author(s), 2023.
