Interpersonal Rejection Anxiety Questionnaire (IRAQ): Psychometric Properties of the Greek Version

Abstract

The purpose of this work was to evaluate the psychometric properties of the Interpersonal Relationship Anxiety Questionnaire (IRAQ) in Greek adults of the general population. The single factor structure of IRAQ was verified for the Greek context. We used CFA with covariates (MIMIC modeling) for the evaluation of invariance in multiple groups, regressing the latent variables and indicators onto three covariates: 1) age, 2) gender, 3) relationship status. The direct effects of the covariates on interpersonal anxiety were not statistically significant. That is the mean of interpersonal anxiety is not different at different levels of the covariates. Thus, population heterogeneity was absent in IRAQ. The direct effects of the three covariates on all indicators of interpersonal anxiety were not statistically significant. Thus, measurement invariance was supported. Additionally, reliability was adequate. Finally, correlation analysis revealed expected relations with fear of interpersonal relationships and parental rejection. IRAQ is a reliable and valid measure to use in the Greek context.
