Empirical Research Background: Infection control becomes more important after the 2003 SARS epidemic in Hong Kong. People now pay more concern about the competency of ICNs. The competency scale for local ICNs is necessary to guide the training and assessment systematically. Empirical Research Aims: Identify items for the competency scale for ICNs in Hong Kong. Empirical Research Sample: Includes all hospital ICNs of Hong Kong. Sample size: 117 (i.e., The whole population of HK ICNs) Empirical Research Method: 83-item questionnaire on Hong Kong ICN competency developed for another study was employed. Subjects were asked to rate the 5-point Likert scale on the importance of the items as being necessary knowledge and skills for HK ICNs. Empirical Research RASCH: Rating scale diagnostics, analysis of person and item estimates and investigating the problematic persons and items formed the first phase of scale refinement. DIF analysis is used to illuminate possible endorsement differences by important subsamples. Empirical Research Results: The rating scale is functioning well, satisfying the Rasch principles. The initial analysis shows item estimates that will help in the development of training materials and procedures for HK ICNs. Items with satisfactory fit statistics are retained for scale construction. The scale will guide future competency assessment for ICNs and certification requirements can be demonstrated empirically by reflecting on the item hierarchy. Empirical Research Conclusions: The results help to identify the competency items for hospital ICNs in Hong Kong thus guiding the training and assessment for these healthcare specialists.
