The Identity Dynamics Questionnaire (IDQ): Operationalization and Verification of the Identity Dynamics Model

Abstract

The article presents the Identity Dynamics Questionnaire (IDQ) as a method for measuring identity processes and modes included in the identity dynamics model by Oleś. The model refers to general processes of personality development that underlie identity functioning located on two dimensions: the internal experience and the external activity. The new tool was created to validly and reliably operationalize the theoretical proposition and to verify its assumptions and relations between components of the model. Four studies were conducted as successive stages of constructing the IDQ. Studies 1 and 2 aimed to exploratory setting the content of subscales designed to measure four identity processes (integration, reconstruction, adaptation, expansion – part A of the IDQ) and four identity modes (stabilization, fluidity, amplification, pliability – part B of the IDQ). Studies 3 and 4 served to confirmatory analyses concerning the structure of the IDQ and show its validity. The studies showed satisfactory psychometric properties of current version of the new method.
