Unfortunately, research on how they deal with this situation is scarce in the behavioral science literature. In this study, we attempt to fill this gap by emphasizing a methodological aspect of combining structural equation modeling (SEM) and person-item map analysis to the extended model of the theory of reasoned action. Novelty and Methods: We offer the notion of combining SEM and Rasch model analysis to explain the extended of theory of reasoned action. The respondents were blue-collar workers from Indonesia who have not yet started a business. Finding/Results: In line with our goal of applying intersubjective certification to the extended theory of reasoned action (TRA) model in the context of blue-collar workers, our results suggest that religiosity affects entrepreneurial intentions, both directly and indirectly, through attitude. The subjective norms have also been shown to influence the intention of blue-collar workers to become entrepreneurs. The extended TRA model has been proven empirically to have good predictive power, with a total effect of 83%. Conclusion: Regarding the sample issue, the person-item map is excellent for explaining our SEM-based findings. The idea of combining the Rasch model property, which is a persons-items map, requires more empirical support to promote its ability to illuminate SEM-based research explanations.
