The variable results of positive-negative research with schizophrenics underscore the importance of well-characterized, standardized
measurement techniques. We report on the development and initial standardization of the Positive and Negative Syndrome Scale
(PANSS) for typological and dimensional assessment. Based on two established psychiatric rating systems, the 30-item PANSS
was conceived as an operationalized, drug-sensitive instrument that provides balanced representation of positive and negative
symptoms and gauges their relationship to one another and to global psychopathology. It thus constitutes four scales measuring
positive and negative syndromes, their differential, and general severity of illness. Study of 101 schizophrenics found the
four scales to be normally distributed and supported their reliability and stability. Positive and negative scores were inversely
correlated once their common association with general psychopathology was extracted, suggesting that they represent mutually
exclusive constructs. Review of five studies involving the PANSS provided evidence of its criterion-related validity with
antecedent, genealogical, and concurrent measures, its predictive validity, its drug sensitivity, and its utility for both
typological and dimensional assessment.

    ABSTRACT: Prospective memory (PM) refers to the ability to remember to perform intended actions in the future. Although PM deficits are a prominent impairment in schizophrenia, little is still known about the nature of PM in symptomatically remitted patients with schizophrenia. To address this issue, event-related brain potentials (ERPs) were recorded from 20 symptomatically remitted patients with schizophrenia and 20 healthy controls during an event-based PM paradigm. Behavioral results showed that symptomatically remitted patients with schizophrenia performed poorly on the PM task compared with healthy controls. On the neural level, the N300, a component of the ERPs related to PM cue detection, was reliable across these 2 groups, suggesting a degree of functional recovery of processes supporting cue detection in patients with symptomatically remitted schizophrenia. By contrast, the amplitude of the prospective positivity, a component of the ERPs related to PM intention retrieval, was significantly attenuated in symptomatically remitted schizophrenia patients relative to healthy controls. Furthermore, a significant positive correlation between the amplitude of the prospective positivity and accuracy on the PM task was found in those patients, indicating that patients’ poor performance on this task may result from the failure to recover PM cue-induced intention from memory. These results provide evidence for the existence of altered PM processing in patients with symptomatically remitted schizophrenia, which is characterized by a selective deficit in retrospective component (intention retrieval) of PM. Therefore, these findings shed new light on the neurophysiological processes underlying PM in schizophrenia patients during clinical remission.

    • "Schizophrenia was diagnosed by the same two senior board psychiatrists according to ICD-10 and DSM-IV criteria and confirmed using the Operational Criteria for Psychotic Illness (OPCRIT) checklist (McGuffin et al., 1991). Lifetime psychopathology and course of the disorder were also evaluated using the OPCRIT checklist, while current psychopathological manifestation was assessed using the Positive and Negative Syndrome Scale (PANSS) (Kay et al., 1987), and Scales for Assessment of Positive and Negative Symptoms (SAPS and SANS) (Andreasen, 1982, 1990). All participants were Caucasians and came from the same geographic area – Lower Silesia (Poland). "

    • "36.8% of the group were female. The mean scores on the Positive and Negative Syndrome Scale (PANSS; Kay et al., 1987) were 16.3 (SD = 5.4) for the positive syndrome, 14.7 (SD = 4.6) for the negative syndrome, and 33.3 (SD = 6.8) for the general psychopathology score. The majority was taking antipsychotic medication (n = 15). "

    ABSTRACT: In psychosis, the alleged increased subjective stress-sensitivity is reflected in abnormal physiological arousal such as higher heart rate, elevated skin conductance levels, decreased vagal activity, and unusual cortisol levels. Despite ongoing research, possible mechanisms that explain the interplay between the phenomenological (i.e., subjective stress and symptoms) and psychophysiological processes are not thoroughly understood. Building on the model of neurovisceral integration by Thayer and Lane (2000) that focuses on regulative mechanisms, we postulate that emotion regulation will be associated with vagal activity, and with both subjective and physiological stress. In the present analysis, we used data from a baseline relaxation period including a 5-minute assessment of heart rate variability (HRV), salivary cortisol, and momentary subjective stress ratings from a sample of 19 participants with psychosis (mean age=40.9, SD=11.1; 36.8% female). Emotion regulation modification skills were assessed for specific emotions (i.e., stress and arousal, anxiety, anger, sadness, shame) if these were present during the previous week. Vagal HRV was significantly and moderately associated with emotion regulation. Both stress parameters (i.e., cortisol, subjective stress) were significantly associated with emotion regulation, but not with HRV. We provide preliminary support for the notion that emotion regulatory processes represent a crucial link between phenomenological and psychophysiological phenomena in psychosis. A potential model that ascribes emotion regulation a central role in the restoration of homeostasis is discussed. Future studies are needed to verify its generalizability and predictive value.
