Exploring the psychometric properties of the Rainbow Model of Integrated Care measurement tool for care providers in Australia

Abstract

ObjectiveTo assess the reliability and validity of a shortened version of the Rainbow Model of Integrated Care (RMIC) measurement tool (MT). The original version of the measurement tool has been modified (shortened) for the Australian context.DesignValidation of the psychometric properties of the RMIC-MT.SettingHealthcare providers providing services to a geographically defined rural area in New South Wales (NSW), Australia.ParticipantsA sample of 56 healthcare providers providing mental and physical healthcare.Main outcome measuresThe psychometric properties of the tool were tested using principal component analysis for validity and Cronbach’s alpha for reliability.ResultsThe tool was shown to have good validity and reliability. The 35 items used in the shortened version of the tool were reduced to 29 items grouped into four dimensions: community-governance orientation, normative integration, functional integration and clinical-professional coordination.ConclusionsThe shortened version of the RMIC-MT is a valid and reliable tool that evaluates integrated care from a healthcare provider’s perspective in NSW, Australia. In order to assess the tool’s appropriateness in an international context, future studies should focus on validating the tool in other healthcare settings.
