Although it is widely used in clinical trials in Brazil, it is not fully validated. The aim of this study is to assess the factor structure of the Brazilian PANSS and generate validation data for its current version. A total of patients diagnosed with schizophrenia were enrolled. Principal component analysis suggested a forced five-factor final model that accounted for Schizophrenia is a heterogeneous disorder with a wide range of symptoms.

Positive and Negative Syndrome Scale

This extensive clinical variability poses a challenge for establishing accurate diagnosis and assessing treatment response. It is composed of 30 items divided into three subscales – Positive Symptoms, Negative Symptoms, and General Psychopathology – developed to assess the severity pansz symptoms and measure general psychopathology and drug-related changes.

It is one of the instruments most frequently used to assess efficacy of antipsychotic drugs, based on variation of its total score over time. For use in Brazil, PANSS was translated into Brazilian Portuguese by means of a standard cross-cultural adaptation process, and its inter-rater reliability was evaluated. The sample comprised individuals with a diagnosis of schizophrenia recruited from three different centers: The inclusion criteria were a diagnosis of schizophrenia, as defined by sscala DSM-IV; age between 12 and 65 years; and absence of severe intellectual disability assessed by family report.

Overall, participants The mean age at illness onset was All patients were receiving antipsychotics. The mean Global Assessment of Functioning score was Eight experienced psychiatrists were trained in both instruments through regular meetings and clinical supervision. The factor structure of the PANSS was fitted in a six-factor model by principal component analysis PCAwith eigenvalues higher than one being retained for factor extraction.

Positive and Negative Syndrome Scale – Wikipedia

esfala The internal consistency of each factor was determined by Cronbach’s alpha. The PCA suggested six factors by the eigenvalue-one criterion. The motor factor presented a Cronbach’s alpha of 0. Results of the rotated principal component matrix with five and panws factor loadings accounted for Regarding sampling adequacy, the Kaiser-Meyer-Olkin test value of 0.

We evaluated the factor structure of the Brazilian version of the PANSS and found a five-factor model similar to those previously described in the literature: Some previous studies found different number of factors.

Most recent studies found five to seven factors. Regarding the composition of individual factors, the negative factor accounted for the greatest individual contribution to variance in the final model The Excitement factor was composed of the same items noted in the study performed by Wallwork et al.

Regarding the sixth factor found and not included in the final model, Emsley et al. Either way, first-episode patients could be escalaa vulnerable to motor symptoms, which may have biased previous studies. Finally, these results should be interpreted in light of some limitations. Our sample was composed of individuals recruited from three different centers, from all stages of the disorder, under various antipsychotic treatment regimens, pansa assessed by different psychiatrists, which resembles pwnss clinical reality of schizophrenic patients and reinforces the strength and validity of the current Brazilian version.

The final eacala model of the Brazilian version of the PANSS presented a performance very similar to the original English version and to those in several other languages, suggesting convergent validity. PANSS is one of the most important primary outcome measures used to evaluate treatment efficacy in psychiatry, and this study shows, for the first time, that its Brazilian version is valid.
