Identity status classifications for the EIPQ are assigned based on a median split procedure.
Questionnaire packets containing the EIPQ and the EOM-EIS-II were distributed to participants in class.
Psychometric analyses are reported as internal reliability coefficients (Cronbach's alpha) computed on the ideological, interpersonal, and overall scales from the EIPQ and the EOM-EIS-II.
The hypothesis that identity status assignments would be consistent between the EIPQ and the EQM-EIS-II was tested in three steps.
Cronbach's alpha values were computed for the shortened (three-domain) ideological, interpersonal, and overall scales from the EIPQ and the EOM-EIS-II.
Correlations Between the EIPQ and EOM-EIS-II Scales
The EIPQ is an objective instrument that generates scores for exploration and commitment, sums those scores across eight domains, and uses median splits to categorize individuals into identity statuses.
The EIPQ contains 32 items, 16 assessing exploration and 16 targeting commitment.
The EIPQ was presented first, followed by the Identity Style Inventory.
Exploration and commitment scores from the EIPQ were transformed into identity status scores using the formulae introduced in this article.
Explained variance obtained using the EOM-EIS was subtracted from that obtained using the EIPQ.
All participants completed the EIPQ and Identity Style Inventory in a research laboratory on the university campus.
