Abstract
Annett's handedness questionnaire is one of the most frequently used diagnostics tool in laterality research. The aim of this study was to evaluate the latent factor structure of this diagnostic tool.
Using the structural equation modeling we conclude that the Annett's handedness questionnaire is a unidimensional instrument. We identified four items in the questionnaire (), which do not contribute adequately to measuring intended theoretical concept.
Thus we recommend exclusion of these items when using AHQ in Czech environment. After their removal it is possible to create reliable composite score (McDonald's ω = 0,97) by summing up results in remaining items (weighing of the items is not necessary).
