Construct validity of the structure of general interests questionnaire

The construct validity of the Slovak version of the structure of general in terests questionnaire (Bergmann and Eder, 1992) was tested in the sample of 108 pupils. The Holland's theoretical postulate (1973) concerning the hexa gonal asserting of interests that represents the theoretical starting point of the tested questionnaire was confirmed by means of correlation analysis . The exception is discussed when the positive correlation between the near -by interests postulated by the model was not confirmed. The correlation of questionnaire scales with the instrument measuring the different construct is low according the expectancy, and the tested differences between gender s were in accord with the findings of authors of the original instrument. T he six factors structure of the instrument couldn't be convincingly confirm ed by the factor analysis and first the repeated rotations with elimination of a number of items enabled author to find the acceptable solution. Where as the results of factor analysis suppose the elimination or modification o f a number of items, the correlations of items with scales are satisfactory convincing and support the opinion that the structure of general interests questionnaire can be considered as the valid instrument.
