Abstract:
One of the main concerns for cancer patients is the progression of the disease and their health. This study sought to examine the psychometric properties, validity evidence based on relations with other variables, and factorial invariance (by sex, age, and tumor site) of the Spanish version of the Assessment of Survival Concerns (ASC). The instrument was translated into Spanish following a back-to-back translation procedure to ensure linguistic and conceptual equivalence. Participants completed the questionnaire in a paper-and-pencil format as part of a prospective, multicenter study including 1,052 patients who also completed other related psychosocial measures. The findings support the reliability and validity of the ASC scores in assessing cancer-related concerns. The ASC is a brief, unidimensional measure with acceptable fit (RMSEA = 0.038, CFI = 0.998, TLI = 0.995, SRMR = 0.026). A strong invariance solution demonstrated acceptable fit across sex, age, and tumor site. The omega reliability estimate was omega = 0.83. Higher ASC scores were positively associated with greater symptoms of depression, anxiety, and psychological distress, as well as with higher physical symptom burden, indicating that patients experiencing more concern also reported worse psychological and functional outcomes. The Spanish version of the ASC provides reliable and valid scores for assessing cancer-related concerns in patients with metastatic cancer.
