title: Body awareness rating questionnaire: measurement properties.
abstract: The purpose of present study was to investigate important measurement properties of the Body Awareness Rating Questionnaire (BARQ) subscales: Function; Mood; Feelings; and Awareness. Samples of 50 patients with prolonged musculoskeletal pain and psychosomatic disorders, and 50 gender and age-matched healthy persons participated in the study. Relative (ICC 2,1) and absolute reliability (S(w)) were calculated. Construct validity was examined by testing hypothesis using Pearson (r) or Spearman rank (r(s)) correlation. Discriminate ability was examined using a receiver operating characteristic (ROC) curve, the area under the curve (aROC) being the measure of discriminative validity. All patients reported more or less improvement after treatment, using the Patient Global Impression of Change (PGIC) as an external indicator of important change. Responsiveness to important change was therefore examined by one-way repeated measures analysis of variance (ANOVA), relating change scores of BARQ subscales to the PGIC categories. Relative and absolute reliability values were within recommended limits for all four subscales. Construct and discriminate validity was indicated for Function, Feelings and Awareness, but not for Mood. Responsiveness was indicated for the subscales Function and Awareness, but not for Feelings and Mood. Further research is needed to complement the subscales of BARQ, found with appropriate measurement properties.
