Negative Symptom Dimensions of the Positive and Negative Syndrome Scale Across Geographical Regions: Implications for Social, Linguistic, and Cultural Consistency.
Anzalee Khan,Lora Liharska,Philip D. Harvey,Alexandra S. Atkins,Daniel Ulshen,Richard S.E. Keefe +5 more
TL;DR: Recognizing the discrete dimensions that underlie negative symptoms in schizophrenia and how these dimensions are understood across localities might result in better understanding and treatment of these symptoms, and suggest that the Positive and Negative Syndrome Scale negative symptom factor can be better represented by a two-Factor model than by a single-factor model.

The Role of Motivation in Cognitive Remediation for People with Schizophrenia
TL;DR: This chapter describes the theoretical determinants of motivation to learn and illustrates how those determinants have been translated into therapeutic techniques that enhance intrinsic motivation in a clinical context and how those techniques yield treatment-related improvements within cognitive remediation therapy and, more broadly, in other behavioral skills-based interventions for schizophrenia.

TL;DR: Results may suggest that metacognitive deficits are a risk factor for elevated levels of negative symptoms in the future, after controlling for baseline negative symptoms, neurocognition, defeatist beliefs and capacity for affect recognition.

TL;DR: The positive emotions program for schizophrenia (PEPS) is a new method that specifically aims to reduce the syndrome of a diminished capacity to experience and was built considering a recovery-oriented approach to schizophrenia.

The Brief Psychiatric Rating Scale
John E. Overall,Donald R. Gorham +1 more
TL;DR: The Brief Psychiatric Rating Scale (BRS) as mentioned in this paper was developed to provide a rapid assessment technique particularly suited to the evaluation of patient change, and it is recommended for use where efficiency, speed, and economy are important considerations.

Cluster Analysis
TL;DR: This fourth edition of the highly successful Cluster Analysis represents a thorough revision of the third edition and covers new and developing areas such as classification likelihood and neural networks for clustering.

Cluster analysis
TL;DR: Cluster analysis is a multivariate procedure for detecting natural groupings in data that resembles discriminant analysis in one respect—the researcher seeks to classify a set of objects into subgroups although neither the number nor members of the subgroups are known.

Negative Symptoms in Schizophrenia: Definition and Reliability
TL;DR: The developed Scale for the Assessment of Negative Symptoms has excellent interrater reliability and the five symptom complexes defined by the scale have good internal consistency, which indicates that the conceptual organization of the scale is also cohesive.
