Fragebogen zu psychologischen Einflussfaktoren der Nutzung von Pkw, ÖPNV und Fahrrad (PsyVKN): Faktorenstruktur, psychometrische Eigenschaften und Validierung

Abstract

Subjective evaluations of different transport modes are often included in standardized transport surveys to analyze the reasons for interindividual variability in the use of travel mode. This paper presents a theoretically based and empirically validated questionnaire on the psychological determinants of choosing car, public transport, and bicycle transportation (PsyVKN), which includes items on control beliefs as well as norms and attitudes related to the respective transport mode. On the empirical basis of six studies with 10,850 participants from more than nine years of psychological mobility research, we developed an economic, reliable, and valid measurement instrument for the psychological characteristics of transport use, based on structural equation models and measurement invariance analyses. This results in eight psychological constructs, operationalized by 21 items, that are now available for future application in interdisciplinary mobility research. These psychological constructs can be employed in transport surveys to evaluate the interindividual variability in the use of travel mode and, subsequently, to plan interventions for reducing car use.
