Scales to measure dimensions of hallucinations and delusions: the psychotic symptom rating scales (PSYRATS).
TLDR
It is concluded that the PSYRATS are useful assessment instruments and can complement existing measures and have excellent inter-rater reliability.Abstract:
BACKGROUND: Scales to measure the severity of different dimensions of auditory hallucinations and delusions are few. Biochemical and psychological treatments target dimensions of symptoms and valid and reliable measures are necessary to measure these. METHOD: The inter-rater reliability and validity of the Psychotic Symptom Rating Scales (PSYRATS: auditory hallucination subscale and delusions subscale), which measure several dimensions of auditory hallucinations and delusions were examined in this study. RESULTS: The two scales were found to have excellent inter-rater reliability. Their validity as compared with the KGV scale (Krawiecka et al. 1977) was explored. CONCLUSIONS: It is concluded that the PSYRATS are useful assessment instruments and can complement existing measures.read more

The influence of semantic top-down processing in auditory verbal hallucinations.
TL;DR: Findings confirm that non-psychotic individuals with AVH are stronger influenced by top-down processing (i.e., perceptual expectations) than healthy controls and suggest that in psychotic patients semantic expectations do not play a role in the etiology of AVH.

TL;DR: Delusion dimensions improved over the two weeks of antipsychotic treatment and admission to hospital, with distress and disruption being more responsive than conviction and preoccupation on both PSYRATS and ESM ratings.

TL;DR: Investigating PPI deficit in relation to the dimensions of auditory hallucinations in patients with schizophrenia or schizoaffective disorder found the inability to consciously ignore auditory hallucinations appears to be associated with a gating deficit.

TL;DR: A first-time observation on the clinical utility of antipsychotic drug type in predicting tDCS effects in schizophrenia is reported, and sex-specific differences suggest potential estrogen-mediated effects.

The Positive and Negative Syndrome Scale (PANSS): rationale and standardisation.
TL;DR: It is proposed that two distinct syndromes can be discerned from the phenomenological profiles, and the positive syndrome represents productive features superadded to the mental status and the negative syndrome represents absence of normal functions.

TL;DR: It is shown that highly disparate relationships with voices-fear, reassurance, engagement and resistance-reflect vital differences in beliefs about the voices, and how these core beliefs about voices may become a new target for treatment.
