Lisrel Analyses Of The Riasec Model: Confirmatory And Congeneric Factor Analyses Of Holland's Self-Directed Search, Gregory J. Boyle, Sergio Fabris

A sample of 401 apprentice plumbers was administered the Australian version of Holland's [(1977) Self-Directed Search: A guide to educational and vocational planning.

Both exploratory (iterative principal factoring with oblique simple structure rotation), as well as LISREL confirmatory factor analyses (CFA), provided only partial support for the six-factor RIASEC typological model on which the SDS instrument was structured. Indeed, only one RIASEC factor (Artistic) was supported unequivocally from the exploratory factor analysis while the CFA statistics indicated a poor …

The Menstrual Distress Questionnaire (MDQ) is the most frequently used self-report instrument for measuring menstrual cycle symptomatology. However, its internal structure has been criticized.

In order to clarify the structural dimensionality of the MDQ, exploratory, congeneric and confirmatory factor analyses of the MDQ item intercorrelations were …
