The paper presents an investigation of the dimensionality of the need for structure construct in two scales - PNS (Thompson et al., 2001) and NFCS (Bar-Tal, 1994) on three Slovak samples (N = 1093). In Study 1 we tested four models by means of confirmatory factor analysis. Results indicate that need for structure is a multi-dimensional construct. In Study 2 the convergent and discriminant aspects of validity were examined. Results indicate good convergent and discriminant aspects of validity of these two scales and also support the two-factor structure of the need for structure construct. The integrative potential of examining the need for structure construct in relation to social perception, personality and motivation is discussed.
