Assessing Multisensory Sensitivity Across Scales: Using the Resulting Core Factors to Create the Multisensory Amplification Scale

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

A comparison of pain, fatigue, and function between post–COVID-19 condition, fibromyalgia, and chronic fatigue syndrome: a survey study

“…The Multisensory Amplification Scale (MSAS) was used to assess heightened sensitivity to vision, hearing, tactile, smell, and internal bodily perceptions. 7,129 The MSAS analyzes multisensory systems where each statement is rated from 1 “not at all” to 5 “extremely true.” Higher scores indicate a higher level of generalized nonnoxious somatosensory amplification. A 7-tem short form of the MSAS was used, with normative values adapted from prior research in a general population: median score of 19.0, lower quartile of 15.0, and upper quartile of 23.0 out of a range of 7 to 35.…”

Multisensory sensitivity differentiates between multiple chronic pain conditions and pain-free individuals

“…Multisensory sensitivity was assessed using the multisensory amplification scale (MSAS), a validated measure of MSS 58 modified from the Somatosensory Amplification Scale 10 to incorporate additional sensory domains. The MSAS consists of 12 items that assess sensory sensitivity (high and low) to normal everyday occurrences involving visual, auditory, tactile or food texture, olfactory, and internal somatic sensations.…”

“…The MSAS has demonstrated good construct validity, internal consistency (Cronbach alpha = 0.82), and excellent test–retest reliability (ICC 3,1 = 0.90). 58…”

“…The MSAS has demonstrated good construct validity, internal consistency (Cronbach alpha 5 0.82), and excellent test-retest reliability (ICC 3,1 5 0.90). 58 In addition to the continuous MSAS score, each individual was assigned to a categorical MSS level: high, high average, low average, and low based on previously reported sex-specific quartile cut-offs (Table 2). 58 Respondents (n 5 647) in the previous study included both pain-free individuals and those reporting a range of pain intensities, recruited regardless of health conditions.…”
