Equivalent Validity of Identification-Commitment-Inventory (HSA-ICI)

the main purpose of this study was to demonstrate the validity of the identification-commitment-inventory (hsa-ici) in two european samples (from spain and portugal). the ici was proposed by quijano and collaborators as part of the human system audit (hsa), a conceptual model and set of tools designed for evaluation and intervention in human resources systems (hrs). the underlying factor structure of the instrument was tested with samples of spanish (n = 625) and portuguese (n = 520) employees - in combination and separately - working in the health care sector. confirmatory factor analysis with a test of invariance across groups was conducted. the results show that the theoretical model fits the observed data of the general sample (χ2 = 2643.12, p = .046; rmsea = .028; rmr = .041; gfi = .983; agfi =. 977; cfi = .994), replicating the results of a previous study. when the samples were analysed separately, the measurement structure presented a better fit in the spanish sample than in the portuguese sample. the overall difference was not large - due to being influenced at the item level by some contextual aspects - but was just sufficient to obtain statistical significance (χ2tucker-lewis = 48.23; df = 1; p < .001). this work provides evidence supporting the use of the hsa-ici. the implications of these results for future research are discussed.
