We hypothesized that the rate would be higher among persons with affective symptoms.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n We included in the study consecutive patients admitted to a first-episode psychosis intervention program. We recorded sociodemographic data from interviews with patients and caregivers and from medical records. We used the Simpson\u2013Angus Rating Scale at baseline to assess parkinsonism and a diagnosis of SP was established if the Simpson\u2013Angus score was \u2265 0.3.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n A total of 174 patients were examined; of these, only 4 (2.3%; 2 Chinese women, 1 Chinese man, and 1 Malay man) had SP. There was a significant difference in the rates of SP in patients with affective psychosis and schizoaffective disorder, compared with those with nonaffective psychoses (15.4% vs 1.2%; \u03c7\n 2<\/jats:sup>\n = 10.7, P = 0.001).
