Corrigendum to ‘Is there a discrete negative symptom dimension in people who use methamphetamine?’Comprehensive Psychiatry 93 (2019) 27–32

Abstract

The authors regret to inform the journal audience that three errors were published in the original version of this article. First, the total sample size of participants included in this study was 153. The sample was incorrectly listed as 154 in the Abstract (Method paragraph) and Results (Section 3.1). Second, there were two instances where the reported percentage of participants within “low-symptoms class” (Class 3) was incorrect (38%). This error occurred in the Abstract (results paragraph) and the Results (Section 3.4). In actuality, 25% of the sample (38 participants) were represented in the “low-symptoms class”. The authors would like to apologise for any inconvenience caused. Finally, when describing the exploratory factor analysis (Section 3.2), the second sentence “The three-factor model reported the lowest BIC value and the two-factor solution reported the lowest AIC value” should have read “The three-factor model reported the lowest BIC value and lowest AIC value”.
