Personality correlates and gender invariance of wording effects in the German version of the Rosenberg Self-Esteem Scale
The Rosenberg Self-Esteem Scale (RSES) is designed to provide an evaluation of one's self-worth. Investigations on the dimensionality of the RSES do not result in simple unifactorial solutions. The direction of the item wording has been suggested as a reason for the contamination of its factorial structure. Latent factor approaches allow for the modeling of method effects, and, particularly in bifactor models, configurations with substantive as well as additional specific factors can be specified. This paper analyzes data from a longitudinal survey in Germany. A bifactor solution with one substantive and two specific factors related to positive and negative wording performs best out of ten …
From Bi-Dimensionality to Uni-Dimensionality in Self-Report Questionnaires
Abstract. The common factor model – by far the most widely used model for factor analysis – assumes equal item intercepts across respondents. Due to idiosyncratic ways of understanding and answering items of a questionnaire, this assumption is often violated, leading to an underestimation of model fit. Maydeu-Olivares and Coffman (2006) suggested the introduction of a random intercept into the model to address this concern. The present study applies this method to six established instruments (measuring depression, procrastination, optimism, self-esteem, core self-evaluations, and self-regulation) with ambiguous factor structures, using data from representative general population samples.
