Description of methods used for collection/generation of data: RedCap (community-dwelling adults; adults with musculoskeletal pain; adults with spinal cord injury) 2. Methods for processing the data: Descriptive statistics are reported for demographic, lifestyle, and general health information. The Rasch model is a probabilistic model, which states that a person with a higher ability on a certain construct (i.e., body awareness ability) would have a higher probability of obtaining a better score on the scale (i.e., in this case a lower score) measuring that construct. For adults with musculoskeletal pain and the group of community-dwelling adults with and without pain, we based our sample size on the Rasch Reporting Guideline for Rehabilitation Research (RULER) guideline’s recommendation that useful information can be obtained from sample sizes of n≥100 if the mean error variance can be narrowed to ≤0.25. For pilot data in our group of SCI, we based our sample size on RULER guidelines recommendation that sample size ≥30 is sufficient for pilot data. We assessed the BARQ-R with Rasch Measurement Theory using a Polytomous Partial Credit Model and analyzed the data through the Rasch Unidimensional Measurement Model (RUMM2030) software. Output was reported following the RULER guidelines. We evaluated: (1) the presence of reversed thresholds; (2) item and person fit, with item and person misfit reflected by fit residuals above 2.50 with significant Bonferroni corrected p-values, when the significance level is set at α=0.05; (3) targeting of the population, with good targeting reflected by the average person location being within 0.5 logits above or below the average item location (set by default at 0 logits±1 standard deviation) and less than 15% floor and ceiling effects; and (4) PSR, which reflects how well we can distinguish groups of persons high versus low levels of body awareness ability, with PSR≥0.70 sufficient for group decisions and PSR≥ 0.90 sufficient for individual decisions. We also evaluated (5) Local item dependence (LID), measured through residual correlations, with those at least r=0.20 above the average correlation, indicating pairs of items that are more correlated with each other, and thus sharing more content with this paired item than with other items in the scale; and (6) unidimensionality tested through Principal Component Analysis of Residuals (PCAR) showing unidimensionality if the eigenvalue is <2.00, and the percent variance on the first residual factor is <10%.[33, 36] Furthermore, if less than 5% of person logit locations are significantly different in a paired sample t-test, created by two subtests of the BARQ-R items, then unidimensionality can be confirmed. The two subtests are created by items having negative (r <-0.3) vs. positive (r >0.3) loadings with the first principal component. The Rasch analysis results in a hierarchical order of items ranging from the easiest to the hardest item. For analyses revealing good structural validity, we provide a score-to-measure table relating the ordinal total score to the Rasch-based logit score and transformed logit score to 0-100%, for easier use in the clinic or research, as well as a scoring sheet with the new Rasch based items. Of note, these score-to-measure tables can only be used for full datasets. (7) Lastly, we reported whether DIF is present for demographic or lifestyle outcomes whose samples are greater than 200 participants in each subgroup. In our case, DIF could only be calculated in the group of community-dwelling adults with and without pain for type of group (adults with pain;adults without pain), age (less than 65 years of age;65 years or above), sex (men;women), past body awareness practice (yes;no) and current body awareness practice (yes;no). 3.

Number of variables: 20 2. Number of cases/rows: 701 3. Missing data codes: There are missing rows/cases when: - people did not pass the consent form quiz - people misunderstood and gave the iPad back after completing the consent quiz (but did not fill in any of the demographic data or questionnaires) - people started filling in the questionnaires and then stopped midway before completing the BARQ-R 4.
