Generalizability of Change Scores on the Body Awareness Scale

Abstract

The Body Awareness Scale (BAS) is an as-yet unpublished measure of somatic arousal that is still in the process of being validated. The purpose of this study was to examine the dependability of changes in BAS scores from baseline to precompetition. Twenty-two male collegiate athletes completed the BAS on 2 separate occasions: baseline and precompetition. Generalizability theory was used to examine the score consistency or dependability of observed baseline scores, observed precompetition scores, and observed baseline to precompetition change scores on the BAS. Results indicated that the BAS had a relatively low generalizability at baseline for these athletes. However, the precompetition scores and the change scores both demonstrated relatively high levels of generalizability. It was concluded that the BAS in its present 14-item form had a high enough generalizability coefficient to support its intended uses.
