The Mini International Neuropsychiatric Interview, version 6, module K (MINI6-Mod-K) is a diagnostic tool to confirm schizophrenia; whereas the Positive and Negative Syndrome Scale in Schizophrenia (PANSS) is a scale to assess psychotic symptoms severity. The objective of this study was to cross-validate the diagnostic questions (categorical) from the Arabic MINI6-Mod-K with the corresponding items’ scores (dimensional) from Arabic PANSS. Arab subjects (N = 101) were recruited from the Psychiatry Hospital in Qatar. MINI6-Mod-K was used to confirm schizophrenia diagnosis, and PANSS was administered to assess psychopathology by an independent rater. The most common symptoms according to MINI6-Mod-K were the delusions and hallucinations but the PANSS items scores ≥2.5 captured more positive responses on all the diagnostic features of schizophrenia. The cut-off PANSS scores that significantly distinguished between the presence or absence of schizophrenia features on MINI6-Mod-K were mostly between 2.5 and 3.5. Multivariate linear regression showed that negative symptoms and disorganized/catatonic behaviors independently contributed to the PANSS score on positive symptoms subscale. However, none of the symptom questions in the MINI6-Mod-K were significant predictors of the PANSS negative score. Our results showed that there is very good cross-validation between the diagnostic questions of Arabic MINI6-Mod-K and the corresponding positive cut-off scores in Arabic PANSS.
