“…Despite guidelines emphasising the need to routinely assess adversity exposure in psychiatric serviceusers (National Health Service Confederation, 2008), research suggests such recommendations are often not implemented (Read et al 2007;Fisher et al 2011;Hepworth & McGowan, 2013).While staff should not pre-suppose a history of maltreatment unless confirmed by the client, the current findings support the contention that clinicians should receive support and training for making routine evaluations for possible experiences of maltreatment. This is particularly important given the significant under-detection of posttraumatic stress in patients diagnosed with psychosis (Salyers et al 2004;Lommen & Restifo, 2009;Mauritz et al 2013), and that such individuals are less likely to receive an appropriate clinical response (e.g., trauma-focused interventions) relative to those with non-psychotic diagnoses (Agar & Read, 2002;Salyers et al 2004;Grubaugh et al 2011) especially in instances where healthcare workers have strong convictions about biogenetic aetiology (Read & Fraser, 1998;Young et al 2001;Agar & Read, 2002).…”
