Abstract

We describe a practical approach to tackling observed heterogeneity using partial least squares structural equation modelling (PLS-SEM) when the number of categorical variables is high and the context of the research is exploratory. The approach is based on combining classical multigroup PLS-SEM approach and pathmox analysis. We provide practical guidance on using our hybrid multigroup PLS-SEM and illustrate its application using real data for bank employees. In investigating work climate, specifically the relationship between satisfaction and loyalty considering specific drivers (empowerment, company reputation, leadership, pay, and work conditions) and different sources of heterogeneity (gender, age, marital status, education, job level, and antiquity), the hybrid multigroup PLS-SEM identified three partitions defined by juniors, seniors, and managers, and identified significant differences between those groups, specifically in indicating that leadership and pay were more important for juniors, empowerment for seniors, and company reputation and work conditions for managers.

Availability of data and material

The data that support the findings of this study are not available due to legal policy restrictions.

Code availability

The SmartPLS 3.2 software and the genpathmox package in R software version 0.4 provided the model estimates (global and multigroup analysis) and the pathmox analysis, respectively.

Notes

  1. The data were obtained from an organizational study of a Spanish bank collaborating with a Spanish university statistics department. The data had been collected through a survey (run by the bank’s human resource department), consisting of a questionnaire emailed to employees, whose anonymity was guaranteed. The response rate was 94%. The collected data were processed and analyzed by the university statistics department.

  2. We fixed to one (i.e., r = 1) the number of repetitions. According to Shmueli et al. (2019), this is adequate when the prediction is based on a single model. We maintained to 10 the number subsample (i.e., k = 10) as this value respects the minimum required training sample size.
