BAPTISTA, Trino et al. Time-course of the Positive and Negative Affect Schedule (PANAS) during an episode of psychosis: a pilot study. Invest. clín [online]. 2020, vol.61, n.4, pp.316-323.  Epub 21-Feb-2021. ISSN 0535-5133.  https://doi.org/10.22209/ic.v61n4a02.

A central issue in affective science is the assessment of specific feelings in severe mental disorders. The PANAS (Positive [PA] and Negative [NA] Affect Scale) is widely used, and we have described its psychometric properties in Venezuela. Here, the course of the PANAS is described during a psychotic episode requiring hospitalization. Eighteen consecutively admitted patients (56% females) were assisted to answer the PANAS, the Brief Psychiatric Rating Scale (BPRS) and locally designed depression (GE-DEPRE) and anxiety (ANSILET) scales, at admission and at discharge. The PA subscale showed a non-significant increase (p = 0.07), whereas the NA subscale displayed a significant decrease (p = 0.01). In males, at discharge, the NA scale positively correlated with the ANSILET (p = 0.09), whereas the PA inversely correlated with the GE-DEPRE scale (p= 0.007). The PANAS may complement the standard psychological evaluations by monitoring specific affect dimensions, relatively independent from the core psychopathology.
