A confirmatory factor analytic study of the aspects of identity questionnaire (AIQ-IV)

Abstract

To obtain valid and reliable research findings it is important to follow the process to validate measuring instruments. This entails determining the psychometric properties of a measure to eliminate or decrease the presence of measurement errors. Measurement errors have a negative impact on the validity of research findings. The aim of this study was to perform a confirmatory factor analytic study on the Aspects of Identity Questionnaire (AIQ-IV) to assess the model fit of the data. Confirmatory factor analysis was employed as part of the process to assess construct validity of a questionnaire to discover the misrepresenting influences of these measurement errors and to provide a foundation for further research. The AIQ-IV was administered to a sample of 157 participants in the South African context including different race, gender, age and occupation groups, drawn by means of convenient sampling. The research results and fit indices indicated that the data reflected a reasonable model fit. Copyright 2010, University of Pretoria. All rights reserved.
