Career decision-making profiles vs. styles: Convergent and incremental validity

an article by Itamar Gati, Reuma Gadassi and Rona Mashiah-Cohen (Hebrew University of Jerusalem, Israel) published in Journal of Vocational Behavior Volume 81 Issue 1 (August 2012)

Abstract The present research investigated the convergent and incremental validity of the multidimensional model and questionnaire – the Career Decision-Making Profiles (CDMP, Gati, Landman, Davidovitch, Peretz-Asulin, & Gadassi, 2010) – by comparing it to two prevalent decision-making style models.

Study 1 compared the CDMP to the Vocational Decision Style Indicator (VDSI; Walsh, 1986) using a sample of 423 young adults.

Study 2 compared the CDMP to the General Decision-Making Style inventory (GDMS; Scott & Bruce, 1995; based on Harren, 1979) using a sample of 427 individuals.

The results of Studies 1 and 2 supported the convergent validity of the CDMP. Moreover, the results supported the advantage of the CDMP over the VDSI in predicting individuals' stages in the career decision-making process.

Highlights

► We test the convergent and incremental validity of the CDMP, Gati et al. 2010.
► Study 1 compared the CDMP to the Vocational Decision Style Indicator (N = 423) deliberating individuals.
► Study 2 compared the CDMP to the General Decision-Making Style (N = 427).
► The results of both studies supported the convergent validity of the CDMP.
► The results supported the incremental validity of the CDMP over other the VDSI.

Hazel’s comment:
Since I am not, by training or profession, a guidance practitioner I thought I needed to find further information about the systems mentioned in this article. Here is what I found:
Career Decision-Making Profiles: a large number of cites which added little to my understanding of the tool and the 39-statement questionnaire here
Vocational Decision Style Indicator: alas I failed to retrieve anything which would tell me about this tool despite using four different search engines. If you know differently please leave a comment.
General Decision-Making Style: a lot more information here from the Society for Judgment and Decision Making.
