Abstract

Objective

To provide normative values for the Italian population for the Brief Assessment of Cognition in Schizophrenia (BACS), a recent brief neuropsychological instrument for the assessment of cognition in patients with schizophrenia.

Participants

Data were collected from 204 healthy adult Italian subjects, stratified by gender, education and age.

Measurements and results

Tests included in the BACS are the following: list learning, digit sequencing, verbal fluency, token motor task, symbol-coding and Tower of London. Normative values were established using the Equivalent Scores method in order to enable comparison with other neuropsychological tasks commonly used in the assessment of the Italian population. Performance on the BACS was influenced by the commonest demographic variables such as age and education.

Conclusions

The availability of normative data for the Italian population will increase the usefulness of this test for both clinical and experimental purposes.

Sommario

Non esistono ad oggi batterie specifiche brevi e facilmente fruibili in lingua italiana per la valutazione del deficit cognitivo dei pazienti con schizofrenia. Lo scopo di questo studio è di tradurre e tarare sulla popolazione italiana la batteria BACS (Brief Assessement of Cognition in Schizophrenia), un breve strumento di screening creato per indagare in modo specifico gli ambiti cognitivi riconosciuti come quelli con le maggiori disfunzioni e correlati ai sintomi della schizofrenia (memoria verbale, velocità e coordinazione psico-motoria, attenzione, funzioni esecutive e fluenza verbale) e che ha mostrato nella validazione in lingua americana una buona correlazione con batterie neuropsicologiche standard e una buona affidabilità testretest. Il campione è costituito da 204 soggetti italiani stratificati per sesso, età e scolarità. I test inclusi nella BACS sono i seguenti: memoria di lista di parole, riordinamento di cifre, fluenza verbale, compito motorio dei gettoni, associazione simboli-numeri e Torre di Londra. I dati normativi sono stati calcolati con il metodo statistico dei Punteggi Equivalenti, con l’obiettivo di rendere possibile il confronto con altri test neuropsicologici usati comunemente in lingua italiana. Le prestazioni alla BACS sono risultate influenzate da variabili demografiche come età e scolarità, confermando i dati presenti in letteratura. La disponibilità di dati normativi per la popolazione italiana ha la potenzialità di aumentare l’utilità di questo test per scopi sia clinici che di ricerca.
