The Development and Validation of the Interprofessional Attitudes Scale : Assessing the Interprofessional Attitudes of Students in the Health Professions

Although shared learning activities are gradually being introduced to health care undergraduates, it has not been possible to measure the effects of educational interventions on students' attitudes. The main objective of this study was to develop a rating scale using items based on the desired outcomes of shared learning, to assess the 'readiness' of health care students for shared learning activities. A questionnaire study of 120 undergraduate students in 8 health care professions. Principal components analysis resulted a 3-factor scale with 19 items and having an internal consistency of 0.9. The factors have been initially named 'team-working and collaboration', 'professional-identity' and 'professional roles'. The new scale may be used to explore differences in students' perception and attitudes towards multi-professional learning. Further work is necessary to validate the scale amongst a larger population.

The original version of the Readiness for Interprofessional Learning Scale (RIPLS) was published by Parsell and Bligh (1999). Three sub-scales with acceptable or high internal consistencies were suggested, however two publications suggested different sub-scales. An investigation into how to improve the reliability for use of the RIPLS instrument with undergraduate health-care students commenced. Content analysis on the original 19 items involving experienced health-care staff resulted in four sub-scales. These sub-scales were then used to formulate a possible model within a structural equation model. The goodness of fit was assessed using a sample (n = 308) of new first year undergraduate students from 8 different health and social care programmes. The same data was fitted to each of the two original sub-scale models suggested by Parsell and Bligh (1999) and the results compared. The fit of the new four sub-scale model appears superior to either of the original models. The new four factor model was then tested on subsequent data (n = 247) obtained from the same students at the end of their first year. The fit was seen to be even better at the end of the academic year.

Healthcare and social services professionals are being called to engage in interprofessional education (IPE) and interprofessional collaboration (IPC) in order to provide efficient and effective care to clients and patients. As such, it is important to conduct research that contributes to evaluation of collaborative practice. A necessary component to any strong quantitative research methodology is the type of instruments used for data collection. However, identifying valid and reliable instruments to use in this area of research can be a daunting task. The purpose of this paper is to review the quantitative measures (i.e., surveys and questionnaires) described in the interprofessional literature. Twenty-three instruments were identified and analyzed for validity and reliability statistics, sample size, ease of access to items on measure, and applicability of measure to diverse professional populations. The two primary measures reviewed are the Readiness for Interprofessional Learning Scale (Parsell & Bligh, 1998 ) and the Interdisciplinary Education Perception Scale (Luecht, Madsen, Taugher, & Petterson, 1990 ). Limited information existed for the remaining measures. Despite the number of measures available for assessing and evaluating IPE and IPC, most lack sufficient theoretical and psychometric development. Several issues that impact the development of sound measures are discussed and implications for future IPC are proposed.
