The participants had an average age of 29.18 years. More than two-thirds were currently incarcerated for violent offenses. They completed the Prison Preference Inventory to measure their environmental preferences in areas such as freedom, activity, support, social stimulation, privacy, emotional feedback, structure, and safety. In addition, several current adaptation measures were measured, including depression, anxiety, anger, hopelessness, suicidality, and life quality and satisfaction. Information on disciplinary violations and overall adjustment were collected from records. A global adaptation measure was created from all significantly associated measures, and inmates were divided into good and poor adapters. Results revealed that good and poor adapters had significantly different environmental preference profiles. Good adapters were more likely than poor adapters to prefer activity and social stimulation and less likely to prefer privacy and freedom. Contrary to conventional wisdom, prior psychiatric history did not differentiate the two groups. Tables, notes, and 27 references (Author abstract modified)
