Conceptualizing PTSD across the time course is necessary to understand the development and maintenance of mental health problems over time. In this Research Topic, Ibrahim and Hassan examine data from Syrian Kurdish refugees living in a refugee camp and exposed to torture and other traumatic events, while Bovin et al. Both these studies have important implications for when treatment is provided and its likely impact.

Ibrahim and Hassan highlight the need for psychological services for Syrian Kurdish refugees that would potentially occur shortly after the traumatic event. This time course from shortly after the trauma to years later indicates the need to conceptualize PTSD as longitudinal, and offer ongoing assessment and targeted treatments at different stages.
The voices of persons with lived experience has been essential in our understanding of psychosis at multiple levels, but has been less widely explored in relation to trauma and psychosis Britz writes eloquently, and with disarming honesty, about her experience of trauma and psychosis, and developing an understanding of the interface between the two while also drawing upon current discourse to highlight the importance of meaningful collaboration with people with lived experience.
Adding to this lived experience perspective is Lu et al. As previously mentioned, although a clear link between trauma and psychosis has been established, the specific mechanisms involved are still unknown. Two papers in this research topic examine potential explanatory models. This paper is the first to propose a theoretical link between early childhood attachment and dissociative processing as mechanisms to explain the origin, and maintenance of distressing voice hearing.
Hardy proposes a comprehensive, theoretically informed model of posttraumatic stress in psychosis that encompasses emotion regulation and autobiographical memory to understand the pathway between victimization and psychosis and provides case vignettes to illustrate how this model informs case formulation and treatment. This approach examines the impact of an intervention on a proposed causal mechanism compared with a control intervention while observing the impact on the symptom of interest.
The authors propose several potential mechanisms, including memory processing, negative posttraumatic beliefs, dissociation, and posttraumatic avoidance with connected interventions. This interventionist-causal paradigm has already been applied in psychosis research 17 and offers a model to better understand proposed mechanisms in trauma and psychosis. Recognizing the debate regarding schizophrenia as a unitary diagnostic category, Stevens et al. The concept of psychosis on a continuum, rather than as a discrete entity, is also of importance to the paper presented by Mayo et al.
This population is important to this topic in that they are a group of individuals who have not yet developed full psychosis, and may indeed not do so, but who are typically experiencing attenuated psychotic symptoms and are distressed and help seeking. Alarmingly, this population reports high levels of childhood trauma and the paper reviews these data while providing clinical recommendations on the assessment, treatment, and future research directions.
As previously discussed, there are concerns in the field about the under-detection of trauma in persons with psychosis or other severe mental illnesses. Under-detection due to professionals failing to screen for trauma and PTSD can be overcome by routine screening of individuals receiving services In line with this theme of the importance of accurate assessment, Rosen et al.

In particular their use of qualitative analysis in the study highlights the importance of careful and sensitive assessment to understanding the time course and impact of trauma on individuals and their mental health. The recovery literature has changed how recovery from mental illness is understood, with a shift from traditional medical definitions that emphasize symptom remission to conceptualizing recovery as a personally meaningful process that involves the development of meaning and a sense of purpose despite symptoms or other challenges 19 In this Research Topic, Mazor et al.
Frueh et al 54 treated 20 patients with PTSD and either schizophrenia or schizoaffective disorder via an week CBT intervention that, consisted of 14 sessions of psychoeducation, anxiety management, and social skills training, as well as 8 sessions of exposure therapy, provided at community mental health centers.
Treatment completers showed significant. PTSD symptom improvement, maintained at 3-month followup. Moreover, significant improvements existed with regard to other targeted domains eg, anger, general mental health.
At 6-month follow-up, CBT clients had improved significantly more in PTSD symptoms, perceived health, negative trauma-related beliefs, and case manager working alliance.
Conclusions The evidence for an association between childhood trauma and psychosis is steadily accumulating, and exploration of potential mechanistic pathways has begun.Childhood Trauma ~ Relationships Advise ~ Healing Strategies
Emerging findings from longitudinal studies and demonstration of a dose-response relationship in others suggest a role of childhood trauma in the development of psychosis. The relative influence of other variables in this relationship, however, warrants further investigation. Independent from the question of causality, childhood trauma and PTSD are frequent in patients with psychosis and severely affect, course and outcome.
More research is therefore needed to further develop and evaluate appropriate treatments for psychotic patients suffering from the consequences of childhood trauma.
Nevertheless, the existing trials suggest that patients with psychotic disorders can benefit from both presentfocused and trauma-focused treatments, despite severe symptoms, suicidal thinking, and vulnerability to hospitalizations.
