Development Of The Greifswald Questionnaire For The Measurement Of Interprofessional Attitudes

Introduction: The implementation of interprofessional education (IPE) could be a potential approach to dealing with increasing complexity in health care. And thus, encouraging interprofessional collaborations to minimize errors in patient care. However, empirical evidence regarding the effectiveness of IPE is inconclusive. One reason for this is a lack of valid and reliable evaluation instruments. This study aims to illustrate the first steps of the development and validation of a German evaluation instrument for the measurement of interprofessional attitudes.Methods: To achieve high psychometric quality, we first selected relevant attitude dimensions and specified criteria for the wording of the items. The a priori developed factor structure was evaluated via factor analysis and the internal consistencies of the scales were analysed in a sample of medical students and nursing trainees, both participants of an IPE course (n=338). Stability was evaluated in an additional sample of nursing trainees (n=14).Results: The Factor analysis revealed three dimensions. Whereby, the two factors "Relevance of learning interprofessional communicational techniques" (German: Wichtigkeit Techniken interprofessioneller Kommunikation zu lernen) (alpha=.85) and "Doubts, dismissal and perceived barriers" (German: Zweifel, Ableh nung und wahrgenommene Barrieren) (alpha=.73) revealed good to acceptable internal consistency. Third-factor "Attitude towards another profession" (German: Einstel lung zur anderen Berufsgruppe) (alpha=.62) remained below a desired internal consistency of alpha>.70. Factors "Doubts, dismissal and perceived barriers", as well as "Attitude towards another profession" showed sufficient stability for pre-/post-measurements.Discussion: The Greifswald Questionnaire for the Measurement of Interprofessional Attitudes is the first version of a three-dimensional tool to evaluate IPE in German-speaking countries. Results showed insufficient item difficulty in the tested sample, which resulted in an insufficient internal consistency, and retest reliability for some factors. Further studies are required to investigate item difficulty, internal consistency and retest reliability in a postgraduate sample.
