Evaluating Measurement Properties of the Adapted Interprofessional Collaboration Scale through Rasch Analysis.

Area of Science:

• Nursing
• Healthcare Management
• Psychometrics

Background:

• Interprofessional collaboration is crucial for effective healthcare delivery.
• Validated instruments are needed to accurately measure collaboration.
• The Interprofessional Collaboration Scale (IPC scale) assesses nurse-physician teamwork.

Purpose of the Study:

• To evaluate the validity and reliability of the German and Italian versions of the IPC scale.
• To confirm the psychometric properties of the IPC scale using Rasch analysis.
• To assess the suitability of the IPC scale for measuring interprofessional collaboration.

Main Methods:

• Cross-sectional study involving 1182 nurses in northern Italy.
• Rasch analysis applied to assess scale validity and reliability.
• Evaluation of item polarity, stability, and overall scale performance.

Main Results:

• The IPC scale demonstrated good reliability (Cronbach's alpha = 0.92).
• All 13 items showed positive polarity, indicating good construct validity.
• Item stability was confirmed across various demographic and professional factors.

Conclusions:

• The IPC scale is a valid and reliable instrument for measuring interprofessional collaboration.
• The German and Italian versions are psychometrically sound.
• Minor revisions could further enhance the scale's validity.
