Results of an Australian study of the Biggs Study Process Questionnaire (SPQ) are presented. The purposes of the research were to: (1) re-examine the SPQ's internal consistency; (2) explore dimensionality of the SPQ scales; and (3) investigate validity of Bigg's model of the study process complex through factor analysis.

Developed a multifaceted, hierarchical self-concept scale and used the Rasch model to analyze data from 400 Australian college students. Results support a multifaceted, hierarchical model of self-concept, with ideal and real aspects making an unequal contribution as an ordered unidimensional latent trait. (SLD)
