Development of a Scale to Examine Responses to Bodily Sensations

Abstract

<b>Objective:</b> Individual differences in the perception of bodily sensations is known to be associated with affective symptomatology. However, the way people <i>psychologically</i> respond to everyday bodily sensations has not been examined in a systematic and balanced way. Thus, we developed the Bodily Sensations Response Scale (BSRS) to evaluate participants' self-reported cognitive, emotional, and behavioral responses to their bodily sensations. We investigated the scale's factor structure and its psycho-metric properties in two studies.<br> <br><b>Method:</b> In <i>Study 1</i>, 297 participants completed the 50-item BSRS and exploratory factor analysis (EFA) was performed on the responses. In <i>Study 2</i> (<i>N</i> = 284), confirmatory factor analysis (CFA) was used to confirm the factor structure of the 32-item BSRS identified in Study 1.<br> <br><b>Results:</b> In <i>Study 1</i>, the EFA identified a 32-item three-factor solution as the best fit for the data. Factor 1 described a defeat response to bodily sensations, Factor 2 described an acceptance response, and Factor 3 described a sensitization response. In <i>Study 2</i>, the three-factor solution was shown not to be parsimonious. Rather, CFA identified that the 27-item BSRS had two interpretable factors (Defeat and Acceptance) that explained participants' psychological responses to bodily sensations. The Defeat subscale was moderately to strongly correlated with awareness of bodily sensations (i.e., Body Perception Questionnaire-Short Form scores) and depression, anxiety, and stress symptom severity (i.e., Depression Anxiety Stress Scales-21 scores), whereas the Acceptance subscale was unrelated or only slightly negatively correlated to awareness of bodily sensations and depression, anxiety, and stress symptoms.<br> <br><b>Conclusion:</b> The 27-item BSRS provides a psychometrically robust assessment of the way in which people psychologically respond to everyday bodily sensations. The measure can assist researchers to better understand how people psychologically process their salient bodily sensations and how this is linked to psychopathology.
