The development and psychometric properties of the Prison Fellowship- Well-being Index (PF WBI).

Purpose: This paper aims to describe the development and validation of the Prison Fellowship Well-being index (PF-WBI), a new quantitative tool for assessing prisoner and staff well-being within prison cultures.

Design/methodology/approach: The PF-WBI was developed through an iterative process of item creation, administration alongside established well-being measures and a series of data analyses. Data was collected from both staff and prisoners ( = 989) across four North Dakota prisons.
