HSPSC versions

In a second step, pubUcations were reviewed for resrrlts on discriminant construct validity by searching for calculations of inter-correlations among the safety climate dimensiorts. In addition, internal consistency was reviewed by assessing Cronbach s alpha for each of the 12 dimensions. The results on Cronbach s alpha were compared to the original HSPSC version by Soria and Nieva (2004) as well as across Ettropean cormtries. 

The appropriateness of the psychometric properties for evaluating the psychometric properties of the HSPSC versions was assessed by common measures as described in Table 11.5 in the annex to this chapter. 

Internal consistency was reported in all 14 studies, including results from the original HSPSC version (see Table 11.4). In 13 of the studies, the alphas are based on the original HSPSC structure and one study reported Cronbach s alpha, based on scale refinement in EFA. 

Cross-national studies require effective coordination within and between countries. We believe that the first step is a European netwoik of HSPSC users and, to a certain degree, the process of writing this chapter has contributed to such a network by identifying researchers and practitioners with an interest in safety climate assessment. Such a network would also help to connect groups within countries that have developed parallel versions (e.g. Spain and Italy). 

In summary, this chapter highlights that the uptake of the HSPSC in Europe has been rather impressive and that psychometric testing has provided us with the knowledge needed to evaluate the measurement qualities of the various national / language versions. We believe that this is an excellent basis from which we can move forward at both national and cross-national levels.
