Population Children and adolescents aged 8 to 16 years with a DSM-5 diagnosis of PTSD and without psychosis, divided into groups with and without auditory-verbal hallucinations
Duration Two years, with interim reassessments at six months and one year

Keywords Humans Hallucinations Case-control studies Longitudinal studies Prospective studies Emotions Stress disorders, post-traumatic Psychotic disorders Adolescent Child Female Social cognition
Registration NCT03356028
Key findings The protocol proposes that social cognition and emotional markers may serve as prodromal indicators of progression from PTSD to psychotic disorders, and that PTSD and AVH may be connected through sensory, emotional, and cognitive biases along a continuum model. It aims to test correlations between these markers and the presence and persistence of AVH over two years; no results are reported.

Abstract

Introduction: Auditory-verbal hallucinatory experiences (AVH) have a 12% prevalence in the general pediatric population. Literature reports a higher risk of developing AVH in post-traumatic stress disorder (PTSD). The persistence of AVHs during adolescence represents a risk of evolution into psychotic disorders. Social cognition and emotional markers could be considered prodromes markers of this evolution. The objectives of this prospective observational study are to observe social cognition and emotional markers correlation with the presence and persistence of AVH over two years and with the evolution of PTSD and psychotic diagnosis. Methods and analysis: This prospective case-control study, longitudinal over two years (with an interim reassessment at six months and one year), will include 40 participants aged 8 to 16 years old with a diagnosis of PTSD and without a diagnosis of psychosis according to the criteria of DSM-5 (K-SADS-PL). Subjects included are divided into two groups with AVH and without AVH matched by gender, age and diagnosis. The primary outcome measure will be the correlation between social cognition and emotional makers and the presence of AVH in the PTSD pediatric population without psychotic disorders. The social cognition marker is assessed with the NEPSY II test. The emotional marker is assessed with the Differential Emotion Scale IV and the Revised Beliefs About Voices Questionnaire. The secondary outcome measures are the correlation of these markers with the persistence of AVH and the evolution of the patient's initial diagnosis two years later.

Discussion: The originality of our protocol is to explore the potential progression to psychosis from PTSD by cognitive biases. This study supports the hypothesis of connections between PTSD and AVH through sensory, emotional and cognitive biases. It proposes a continuum model from PTSD to psychotic disorder due to impaired perception like AVH.
