Is the Magnetic Resonance Imaging-Anxiety Questionnaire (MRI-AQ) a valid and reliable tool for measuring patient anxiety during MRI examinations?
The MRI-AQ is a newly developed, valid, and reliable 15-item tool specifically designed to measure patient anxiety during MRI examinations.
New MRI-specific anxiety tool available for research; leaves open superiority to generic measures and impact on clinical outcomes or interventions.
AIM: To develop and validate a new instrument measuring patient anxiety during Magnetic Resonance Imaging examinations, Magnetic Resonance Imaging- Anxiety Questionnaire. BACKGROUND: Questionnaires measuring patients' anxiety during Magnetic Resonance Imaging examinations have been the same as used in a wide range of conditions. To learn about patients' experience during examination and to evaluate interventions, a specific questionnaire measuring patient anxiety during Magnetic Resonance Imaging is needed. DESIGN: Psychometric cross-sectional study with test-retest design. METHODS: A new questionnaire, Magnetic Resonance Imaging-Anxiety Questionnaire, was designed from patient expressions of anxiety in Magnetic Resonance Imaging-scanners. The sample was recruited between October 2012-October 2014. Factor structure was evaluated with exploratory factor analysis and internal consistency with Cronbach's alpha. Criterion-related validity, known-group validity and test-retest was calculated. RESULTS: Patients referred for Magnetic Resonance Imaging of either the spine or the heart, were invited to participate. The development and validation of Magnetic Resonance Imaging-Anxiety Questionnaire resulted in 15 items consisting of two factors. Cronbach's alpha was found to be high. Magnetic Resonance Imaging-Anxiety Questionnaire correlated higher with instruments measuring anxiety than with depression scales. Known-group validity demonstrated a higher level of anxiety for patients undergoing Magnetic Resonance Imaging scan of the heart than for those examining the spine. Test-retest reliability demonstrated acceptable level for the scale. CONCLUSION: Magnetic Resonance Imaging-Anxiety Questionnaire bridges a gap among existing questionnaires, making it a simple and useful tool for measuring patient anxiety during Magnetic Resonance Imaging examinations.

Ahlander et al. (2016) conducted a cross-sectional in Anxiety during Magnetic Resonance Imaging. Magnetic Resonance Imaging-Anxiety Questionnaire (MRI-AQ) was evaluated on Psychometric properties including factor structure, internal consistency, validity, and reliability. The 15-item Magnetic Resonance Imaging-Anxiety Questionnaire demonstrated high internal consistency, acceptable test-retest reliability, and known-group validity for measuring patient anxiety.
