METHODS: A total of 402 participants (117 with first-episode psychosis [FEP], 125 with schizophrenia, and 160 controls) completed the BAC app along with clinical and functional assessments. We evaluated internal consistency, group differences, convergent and discriminant validity, and the effects of sex, age, and education. Normative percentiles were derived from controls.
RESULTS: The BAC app showed good internal consistency across groups (α = 0.76-0.87) and effectively differentiated individuals with psychosis from controls (area under the curve [AUC] = 0.862), with performance declining from controls to FEP to schizophrenia. Discrimination between FEP and schizophrenia was limited (AUC = 0.649). BAC App correlated positively with estimated intelligence quotient and functional capacity, and negatively with symptom severity, particularly in FEP. Performance varied by age, sex, and education, supporting the need for stratified normative data.
CONCLUSIONS: The BAC app showed strong reliability and validity for cognitive assessment in Spanish-speaking individuals with psychosis. Its brevity, automated scoring, and normative data support its clinical and research applications for cognitive screening, monitoring, and treatment evaluation.
