To use the Arabic version of the PANSS in Lebanese schizophrenic patients, to check its validity and reproducibility compared to other versions of the questionnaire and to assess risk factors affecting the total PANSS score.
This case-control study, performed between April and August 2016, included 400 patients (200 patients, 200 controls).
The PANSS scale items converged over a solution of three factors, explaining a total of 64.81% of the variance. A high Cronbach’s alpha was found for the full scale (0.961), the positive symptoms (0.877), negative symptoms (0.933) and general psychopathology (0.926). A stepwise linear regression, using the total PANSS score as continuous variable, showed that low socioeconomic level and male gender would significantly increase the total PANSS score (Beta = 13.139, CI 7.570-18.708, p < 0.001 and Beta = -8.614, CI -13.884 – -3.345 p = 0.001).
This study shows that the Arabic version of the PANSS has promising psychometric properties, and thus it is a good tool to use for the diagnosis of patients with schizophrenia. Based on this study, health care professionals and researchers can readily use the PANSS questionnaire to estimate the overall severity of schizophrenia among psychiatric patients in Lebanon.
