Abstract
The bandwidth-fidelity dilemma is a controversially discussed problem in personality measurement. In this study, we contrasted the utility of broad versus narrow personality traits in an admission exam for teacher students. We compared the Big Five and narrow personality constructs (social-communicative behavior, achievement behavior, health and recreation behavior), which were part of an assessment battery for teacher student selection (N = 1120), regarding overlap and predictive validity. As criterion variables, academic satisfaction (N = 184) and GPA (N = 680) were assessed later. Reasonableness of including both questionnaires in one assessment may be questioned in terms of overlap of the personality inventories. Results show that health and recreation behavior cannot be covered by the Big Five in a selection procedure. Empirically, both broad and narrow traits show predictive validity for academic success and satisfaction.
Highlights
The bandwidth-fidelity dilemma is a controversially discussed problem in personality measurement
The bandwidth-fidelity dilemma states that the bandwidth of a predictor has influence on the criterion validity
In other words, when selecting candidates applying for teacher education, it seems important to predict whether they will be successful in their studies and whether they have the potential to be good teachers
Summary
The bandwidth-fidelity dilemma is a controversially discussed problem in personality measurement. We compared the Big Five and narrow personality constructs (social-communicative behavior, achievement behavior, health and recreation behavior), which were part of an assessment battery for teacher student selection (N = 1120), regarding overlap and predictive validity. Results show that health and recreation behavior cannot be covered by the Big Five in a selection procedure Both broad and narrow traits show predictive validity for academic success and satisfaction. Broad criteria, such as overall work success, are of interest and narrow criteria, such as burnout This is the case in a newly developed teacher student assessment in which two bandwidthwise different personality measures were used. The selection tool involves three steps; here, we only examine the second part, namely a psychometric test battery
