“…The third sample was drawn from a RCT for treatment of PTSD among 132 participants recruited from 12 vocational rehabilitation programs at community mental health centres in three Northeastern states in the USA (Study 3; n =125; Lu et al ., 2022). Inclusion criteria for Study 3 were: (1) >18 years old; (2) received supported employment services within the past 24 months; (3) in treatment for SMI, with diagnosis based on self-report; (4) current diagnosis of PTSD, determined by the CAPS-5 (Weathers et al ., 2018); (5) no current chart diagnosis of alcohol or drug dependence; and (6) no hospitalizations or suicide attempts in the past two months.…”

Background: People with post-traumatic stress disorder (PTSD) exhibit negative cognitions, predictive of PTSD severity. The Post-Traumatic Cognitions Inventory (PTCI) is a widely used instrument measuring trauma-related cognitions and beliefs with three subscales: negative thoughts of self (SELF), negative cognitions about the world (WORLD), and self-blame (BLAME). Aims: The current study attempted to validate the use of the PTCI in people with serious mental illness (SMI), who have greater exposure to trauma and elevated rates of PTSD, using confirmatory factor analysis (CFA) and examining convergent and divergent correlations with relevant constructs. Method: Participants were 432 individuals with SMI and co-occurring PTSD diagnosis based on the Clinician Administered PTSD Scale, who completed PTCI and other clinical ratings. Results: CFAs provided adequate support for Foa’s three-factor model (SELF, WORLD, BLAME), and adequate support for Sexton’s four-factor model that also included a COPE subscale. Both models achieved measurement invariance at configural, metric and scalar levels for three diagnostic groups: schizophrenia, bipolar and major depression, as well as for ethnicity (White vs Black), and gender (male vs female). Validity of both models was supported by significant correlations between PTCI subscales, and self-reported and clinician assessed PTSD symptoms and associated symptoms. Conclusions: Findings provide support for the psychometric properties of the PTCI and the conceptualization of Sexton’s four-factor and Foa’s three-factor models of PTCI among individuals diagnosed with SMI (Foa et al., 1999).

“…The PCL‐5 assessed 20 PTSD symptoms on a 5‐point scale; total scores ranged from zero to 80, with higher scores indicating higher presence and impact of PTSD symptoms that week (Weathers et al, 2013). Excellent internal consistency and convergent validity have been determined with a serious mental illness cohort (Lu et al, 2022).…”

“…For example, psychotic-like symptoms which occur primarily in response to trauma cues (e.g., situational triggers, anniversary of the trauma) may be more indicative of PTSD, whereas psychotic-like symptoms which occur without a particular cue or in response to stressors more broadly may be more indicative of a psychotic disorder. Importantly, studies have demonstrated that common assessment tools for PTSD (e.g., CAPS-5, PCL) are valid for use among individuals with psychotic disorders, 131 , 132 and researchers have also developed modified versions of these tools to assess for co-occurring PTSD among individuals with schizophrenia. 131 …”

Early detection of psychotic-spectrum disorders among adolescents and young adults is crucial, as the initial years after psychotic symptom onset encompass a critical period in which psychosocial and pharmacological interventions are most effective. Moreover, clinicians and researchers in recent decades have thoroughly characterized psychosis-risk syndromes, in which youth are experiencing early warning signs indicative of heightened risk for developing a psychotic disorder. These insights have created opportunities for intervention even earlier in the illness course, ideally culminating in the prevention or mitigation of psychosis onset. However, identification and diagnosis of early signs of psychosis can be complex, as clinical presentations are heterogeneous, and psychotic symptoms exist on a continuum. When a young person presents to a clinic, it may be unclear whether they are experiencing common, mild psychotic-like symptoms, early warning signs of psychosis, overt psychotic symptoms, or symptoms better accounted for by a non-psychotic disorder. Therefore, the purpose of this review is to provide a framework for clinicians, including those who treat non-psychotic disorders and those in primary care settings, for guiding identification and diagnosis of early psychosis within the presenting clinic or via referral to a specialty clinic. We first provide descriptions and examples of first-episode psychosis (FEP) and psychosis-risk syndromes, as well as assessment tools used to diagnose these conditions. Next, we provide guidance as to the differential diagnosis of conditions which have phenotypic overlap with psychotic disorders, while considering the possibility of co-occurring symptoms in which case transdiagnostic treatments are encouraged. Finally, we conclude with an overview of early detection screening and outreach campaigns, which should be further optimized to reduce the duration of untreated psychosis among youth.
