Pain Disability Index: Construct and discriminant validity

Archives of Physical Medicine and Rehabilitation, 1991
The Pain Disability Index (PDI) was developed as a self-report measure of general and domain-specific, pain-related disability. This study's purpose was twofold: (1) to assess construct validity of the scale relative to other measures of pain-related disability and psychologic distress and (2) to assess the strength of the PDI, independent of pain ...

A Density Discriminant Index for Cluster Validation

2019 11th International Conference on Information Technology and Electrical Engineering (ICITEE), 2019
Clustering analysis is widely applied in several domains of study. Using a suitable number of clusters is one of the most important factors to influence the performance of clustering. Several algorithms of cluster validation have been developed to find such a number.

Discrimination learning differences and similarities as a function of brain index

Physiology & Behavior, 1974
Abstract Seven tree shrews ( Tupaia glis ), 10 squirrel monkeys ( Saimiri sciurea ), and 12 college students ( Homo sapiens ) were tested on a series of extradimensional shifts involving the position and brightness dimensions. While the number of errors each species made per problem differed and conformed to an index of central nervous system ...
