Abstract

Individuation Test for Emerging Adults–Short (ITEA-S) is a self-report instrument for measuring five aspects of individuation in emerging adulthood. The test consists of two equivalent forms for assessing individuation in relation to mother and father separately. In this study, we adapted the ITEA-S for use in Austrian and German emerging adult populations. In both samples, the two ITEA-S forms demonstrated satisfactory factorial validity and internal consistency. The scores on the five scales were meaningfully related to the Emotional, Functional, and Conflictual Dependence Scales of the Psychological Separation Inventory and also to life satisfaction as measured by the Satisfaction With Life Scale. The results of the multiple-group factor analyses supported the hypotheses of full metric and scalar invariance for both ITEA-S forms across the Austrian and German samples of emerging adults.
