METHODS: A total of 370 participants (99 FEP, 116 schizophrenia, and 155 controls) completed the VRFCAT in a multicenter study. Internal consistency (McDonald's omega), discriminative validity (group comparisons and ROC curves), and convergent validity via correlations with cognitive performance and clinical symptoms were examined. Reference percentiles were calculated from the healthy control sample using quantile regression, stratified by age and education.
RESULTS: Item-level VRFCAT completion times showed acceptable to good internal consistency overall and in controls and schizophrenia samples, but poor in FEP. Differences in VRFCAT performance emerged (χ2 = 108.88, p < .001), with controls performing best, schizophrenia worst, and FEP in between. ROC analyses indicated good discriminative accuracy in distinguishing patients from controls (area under the curve [AUC] = 0.779, sensitivity = 80.0%, specificity = 64.2%); but limited discrimination between schizophrenia and FEP. Age and education, but not sex, significantly affected performance. VRFCAT showed small-to-moderate correlations with cognitive performance, and no significant associations with symptom severity.
CONCLUSIONS: The VRFCAT is a reliable and valid tool for assessing functional capacity in Spanish-speaking individuals with psychotic disorders. Its ecological validity, objectivity, psychometric properties, brief administration time, and ease of use support its potential use in clinical and research settings for evaluating functional recovery and treatment outcomes.
