The study aims to investigate the measurement model of four constructs, namely, spirituality at the workplace (SP), Islamic spirituality (ISP), organizational commitment (OC) and organizational citizenship behaviours (OCB). The study aims to contribute new knowledge to the existing literature whereby performance determinants comprising these constructs, serve to improve employee well-being which ultimately improves organizational performance. Using disproportionate stratified random sampling, the survey data used for this empirical research were drawn from 482 employees working in takaful agencies in Malaysia. After yielding an instrument to measure SP, ISP, OCB and OC, principal component analysis (PCA) using SPSS and confirmatory factor analysis (CFA) using AMOS were carried out.
