Die deutsche Version der Bath Body Perception Disturbance Scale (BBPDS-D)

Abstract

This German translation and cross-cultural adaptation of the original English version of the BBPDS is a valid instrument to assess body perception disturbances in German speaking CRPS patients. Future research should further assess the impact of body perception disturbance on treatment outcome and prognosis.

Validation of the Bath CRPS Body Perception Disturbance Scale

“…This subtle difference in phrasing might be the reason why the internal consistency of the German version (including the item on attention) is much higher (Cronbach's alpha = 0.92) than seen in previous studies. 57 We propose a revised B-CRPS-BPDS (r-B-CRPS-BPDS) excluding the item on attention (see supplementary material for a downloadable version with scoring instructions). Alternative approaches would be to investigate whether rewording this item in the English B-CRPS-BPDS improves its validity, or to create two separate items that independently capture hypervigilance towards, and inattention for the CRPS-affected limb(s).…”

“…51 A prospective study found that body perception disturbance decreased in the first 12 months following the onset of CRPS, along with a decrease of pain, CRPS severity, and disability. 1 However, crosssectional studies found either no effect of disease duration 51,57 or greater body perception disturbance in people with longer disease durations. 32 It is important to note that the latter findings do not mean these symptoms progress and worsen over time, as cases that have been resolved are not captured by these studies.…”

“…The two most used questionnaires to measure body perception disturbance in CRPS are the neurobehavioral questionnaire, 14,15 assessing inattention to and disengagement from the affected limb, and the Bath CRPS Body Perception Disturbance Scale ("B-CRPS-BPDS"), 31 covering a broader range of body perception disturbances. 29,31 Although the B-CRPS-BPDS is widely used in different languages, 1,4,32,36,51,57 its psychometric properties have not been fully explored. In two studies (N=22 and 59), the internal consistency of the English B-CRPS-BPDS ranged from poor to good at different time points.…”

“…Positive relationships between body perception disturbance and pain intensity have been found in some studies, 32,51 but not others. 57 One study found positive relationships between body perception disturbances and depression, anxiety, stress, and quality of life. 51 A prospective study found that body perception disturbance decreased in the first 12 months following the onset of CRPS, along with a decrease of pain, CRPS severity, and disability.…”

Complex Regional Pain Syndrome (CRPS)

“…Eine Möglichkeit der Diagnostik besteht daher neben der aktiven Abfrage dieser Wahrnehmungsstörung auch durch den Einsatz verschiedener Fragebögen wie z. B. die auch deutschsprachig validierte "Bath Body Perception Disturbance Scale" [2].…”
