A preliminary report on the development of a validated tool for measuring psychosocial outcomes for massive weight loss patients

The PBOT was shown to be reliable both in terms of its internal consistency and test-retest reliability. Comparison to the DAS24 demonstrated the PBOT to be valid. However, the cohorts were small and responsiveness was not tested. This needs to be tested in further larger validation studies, ideally, with comparison to functional scales such as the SF-36 or other validated massive weight loss body contouring PROMs; such as the Body Q.
