Interoceptive awareness in a Southeastern US college sample: validation of the multidimensional assessment of interoceptive awareness - version 2.

Objective: The Multidimensional Assessment of Interoceptive Awareness, version 2 (MAIA-2) is a commonly utilized self-report instrument to assess individuals' ability to perceive bodily sensations. The MAIA-2 has displayed variable psychometric properties across samples. Thus, we examine the psychometric properties of the MAIA-2 in a Southeastern United States college sample.

Participants: Our studies consisted of 710 (study 1) and 66 (study 2) college students.

Methods: Study 1 used a cross-sectional research design where we investigated the factor structure, and measurement invariance (e.g., measured similarly across genders). Study 2 examined the test-retest reliability across a three-week period.

Results: The MAIA-2 displayed adequate to good internal consistencies and factor loadings, strict invariance, and questionable temporal stability.

Conclusion: The MAIA-2 demonstrates adequate psychometric properties in this college sample that were similar to the original MAIA sample characteristics. Contextual and cultural factors may influence the subjective experience of interpreting bodily sensations.
