The instrument evaluates weight-related impacts across two primary domains:

Physical Domain (7 items): Includes a 5-item Physical Function composite focusing on mobility and stamina.

Psychosocial Domain (13 items): Assesses the psychological and social impacts of weight.

For clinical trial use, researchers often refer to Meaningful Within-Patient Change (MWPC) thresholds, which are typically estimated between 13.5 and 16.6 points across the various composite scores.
