The scale measures general intelligence.

DESCRIPTION: The WAIS-R (PL) consists of six verbal tests (Information, Digit Span, Vocabulary, Arithmetic, Block Design, Object Assembly, and Digit Symbol) and five performance tests (Picture Completion, Picture Arrangement, Block Design, Object Assembly and Digit Symbol). Raw scores are transformed into transformed scores (for every age group there is separate table) and then into IQ in Verbal Scale, Performance Scale, Full Scale and three factor scores – Verbal Comprehension, Perceptual Organization and Memory and Freedom from Distractibility.

RELIABILITY: High internal consistency of scales (Verbal, Performance and Full) and eight tests (lower for Object Assembly) and high stability of two tests (Digit Span, Digit Symbols).

VALIDITY: Significant correlations with tests measuring “g” (SPM Plus, RFTT) and abstract reasoning (WCST). Scores improve with level of education. The results of validation study indicate that Verbal Scale measures crystallized intelligence and Performance Scale – fluid intelligence. Polish manual contains correlations between WAIS(R) PL scores and two personality variables – anxiety and coping with stressful situations.

NORMS: For 16-79-year-olds (Polish national sample).

APPLICATIONS: Primarily in psychological practice to assess intellect.
