Organisational commitment (OC) has become a hot behavioural topic among researchers, scholars and consulting firms. However, OC instruments have rarely been studied and developed by academics in small and medium-sized Thai enterprises (SMEs). The purpose of this paper is to develop an instrument to measure the OC of Generation Y employees in Thai SMEs.
A measurement scale for OC was established in three stages. First, 16 questions were developed as a questionnaire based on the concepts and theories of OC, and a survey was conducted for 360 Generation Y employees working in various SMEs. Second, the questions were validated using exploratory factor analysis and, finally, confirmatory factor analysis and convergent validity were tested.
The OC instrument presented excellent reliability at 0.865. Three factors of the 16 questions as normative commitment, affective commitment and continuance commitment were extracted. These all passed the general rule of thumb for minimum acceptability of a measurement system.
This OC instrument has concrete psychometric measurements and can be applied by researchers, scholars, practitioners and organisations in other settings, especially in the Thai context. Importantly, factor analysis results suggested that the OC questionnaire was suitable for utilisation and application as is, or with minimal modifications, to various business fields and/or settings.
