Vocabulary and Abstract Thinking Test [VAT-75]

Brief Description

The test consists of two parts. Part A includes 50 words, each accompanied by four possible definitions, from which the participant must select the correct one. Part B includes 25 abstract reasoning questions, where the participant must identify logical patterns based on given data and choose the response that best completes the sequence. The test is a direct adaptation of the Shipley Institute of Living Scale and aims to measure both verbal ability and abstract thinking.

Purpose

The purpose of the test is to estimate the premorbid cognitive level of individuals with suspected brain dysfunction and to contribute to the overall assessment of intellectual functioning, by evaluating verbal competence and abstract reasoning ability.

Scoring Method

The number of correct responses is recorded separately for each part. The final assessment is based on the combined scores of Part A and Part B, with an optional comparative analysis to detect discrepancies between verbal and abstract skills.

Validity

The test is based on the widely used Shipley Institute of Living Scale, which is internationally recognized as a tool for assessing cognitive capacity and decline. Its validity is supported by longstanding use in psychological and neuropsychological evaluations.

Reliability

The reliability of the test is considered high due to the structured nature of the questions and the clarity of the scoring system. International studies on the original version of the scale indicate good internal consistency and test-retest reliability.

Data Analysis and Use

The analysis of the data provides a general overview of the participant’s verbal and cognitive level. The tool can be used in clinical settings to detect cognitive deterioration, in neurological cases, or in situations requiring assessment of abstract thinking and verbal adequacy for diagnostic or research purposes.
