The Child PTSD Symptom Scale (CPSS) is a free checklist designed for children and adolescents to report traumatic events and symptoms that they might feel afterward. [1] The items cover the symptoms of posttraumatic stress disorder , specifically, the symptoms and clusters used in the DSM-IV. Although relatively new, there has been a fair ...
The resulting maps display the individual statements in two-dimensional space with more similar statements located closer to each other, and grouped into clusters that partition the space on the map. The Concept System software also creates other maps that show the statements in each cluster rated on one or more scales, and absolute or relative ...
Clustering high-dimensional data is the cluster analysis of data with anywhere from a few dozen to many thousands of dimensions.Such high-dimensional spaces of data are often encountered in areas such as medicine, where DNA microarray technology can produce many measurements at once, and the clustering of text documents, where, if a word-frequency vector is used, the number of dimensions ...
Insel questioned the validity of the DSM classification scheme because "diagnoses are based on a consensus about clusters of clinical symptoms" as opposed to "collecting the genetic, imaging, physiologic, and cognitive data to see how all the data – not just the symptoms – cluster and how these clusters relate to treatment response." [101 ...
These clusters then could be visualized as a two-dimensional "map" such that observations in proximal clusters have more similar values than observations in distal clusters. This can make high-dimensional data easier to visualize and analyze.
The Multi-dimensional Theory of Anxiety [7] is based on the distinction between somatic and cognitive anxiety. The theory predicts that a negative, linear relationship between somatic and cognitive anxiety, an Inverted-U relationship between somatic anxiety and performance, and that somatic anxiety declines once performance begins although cognitive anxiety may remain high, if confidence is low.
The Dimensional Obsessive-Compulsive Scale (DOCS) is a 20-item self-report instrument that assesses the severity of Obsessive-Compulsive Disorder (OCD) symptoms along four empirically supported theme-based dimensions: (a) contamination, (b) responsibility for harm and mistakes, (c) incompleteness/symmetry, and (d) unacceptable (taboo) thoughts. [1]
A post-traumatic stress spectrum [10] or trauma and loss spectrum [11] – work in this area has sought to go beyond the DSM category and consider in more detail a spectrum of severity of symptoms (rather than just presence or absence for diagnostic purposes), as well as a spectrum in terms of the nature of the stressor (e.g. the traumatic ...
