Psychometric properties of Spanish version of the Mini-Mental Adjustment to Cancer Scale

Background/Objective: The aim of the study was to examine the factor structure and psychometric properties of the Spanish version of the Mini-Mental Adjustment to Cancer Scale (Mini -MAC) in a large sample of patients with non-metastatic, resected cancer. Methods: Prospective, observational, multicenter study for which 914 patients were recruited from 15 Spanish hospitals. Exploratory and confirmatory factor analyses, validity and reliability analyses were conducted. Results: Factor-analytic results indicated a 4-factor structure of the Spanish version of the Mini MAC. Three subscales have psychometric properties similar to those of Helplessness, Anxious preoccupation, and Cognitive avoidance of the original the Mini -MAC. The Fighting spirit and the Fatalism subscales were combined on the Positive attitude scale. The four factor-derived scale scores exhibited acceptable accuracy for individual measurement purposes, as well as stability over time in test-retest assessments at 6 months. Validity assessments found meaningful relations between the derived scale scores, and Brief Symptom Inventory depression and anxiety scores and Functional Assessment of Chronic Illness Therapy spiritual well-being scores. Conclusions: The Spanish version of the Mini -MAC provides reliable and valid measures for patients with non-metastatic, resected cancer, and results corroborate the instrument's cross-cultural validity.
