“…Caplan (1993) found that staff and patient perceptions differed with regard to several scales of the Ward Atmosphere Scale (WAS; Moos, 1968;1989, Moos & Houts, 1974, including order and organization, program clarity and staff control. Possible explanations given in previous research for the divergent perceptions between nursing staff and patients are, the different roles and functions that staff and patients have within a forensic institution (Caplan,1993;Goffman, 1961;Rossberg & Friis, 2004), and the restrictions to the liberty and personal freedom of incarcerated patients (Langdon, Cosgrave & Tranah, 2004). Patients' restricted liberty could also be a potential explanation for the finding that the perception of climate differs as a function of the level of security (Dickens et al, 2014;Long et al, 2011;Milsom et al, 2014).…”
