MAROCCO, Armando and TETREAU, Bernard. Psychometric properties of the Professional Preferences Crystallization Inventory. Rev. bras. orientac. prof [online]. 2003, vol.4, n.1-2, pp. 71-86. ISSN 1679-3390.
The Professional Preferences Crystallization Inventory (PPCI) is an important instrument which evaluates two dimensions: choosing a career and thus promoting professional development. This study presents the steps of the elaboration of the PPCI and the measurement of its psychometric properties obtained with a sample of 487 students from a private university in the south of Brazil, of both sexes and age ranging from 17 and 51 ( = 22; 5% = 21,3; Median = 20; Mode = 19). The results are presented systematically according to its theoretically proposed dimensions. Alpha coefficients for the two dimensions studied are found to be highly satisfactory (a > 0,85). The results of both the factor analysis and correlations (item-item, item-dimension, and item-total scale) seem to support a two-factor solution. Further studies are still needed to proceed with the investigation of other important psychometric qualities.
