Tool Description:

The Sense of Well-Being Inventory (SWBI) was originally developed to assess quality of life for vocational rehabilitation clients. It was later validated and refined by Chapin et al. 2004 in a population with SCI, and again by Catalano et al. 2010. The latest version has 20 items and four subscales. Older versions contain 36 or 26 items, with an additional subscale regarding medical care.
