Objective:
The present study examined the concurrent validity of the Hamburg Wechsler Intelligenztest für Kinder - IV (HAWIK-IV; Petermann & Petermann, 2010) and the Intelligence and Development Scales (IDS; Grob, Meyer & Hagmann-von Arx, 2009).
Methods:
HAWIK-IV and IDS were administered in counterbalanced order to N = 172 children aged 6 to 11 years. The study presents the descriptive statistics, correlations, and an exploratory factor analysis of the data.
Results:
There is a high correlation between HAWIK-IV Full Scale IQ and IDS intelligence score (r = .83). HAWIK-IV indices showed moderate to high correlations with the cognitive scales of the IDS (Cognition, Language, Mathematics). Low to absent correlations were found between HAWIK-IV indices and the noncognitive scales of the IDS (Social-Emotional Competence, Psychomotor, Achievement Motivation). The factor structure can be interpreted meaningfully and allows integration of the IDS cognitive, language, and mathematical subtests into the four HAWIK-IV indices.
Conclusions:
The results show that HAWIK-IV and IDS test results can be related to each other.

Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...
