Personality was assessed at baseline via the NEO Five Factor Inventory (NEO-FFI46). The NEO-FFI is a well-validated 60-item short form of the 240-item NEO-PI-R in which each of the five domains of the FFM is represented by 12 items.(48) Each item is rated on a 5-point Likert scale ranging from “strongly agree” to “strongly disagree.” Psychometric properties of the NEO-FFI domains in this sample have been previously described.(49)
