Trauma associated with abuse in childhood is not only a consolidated risk factor for the onset of psychosis, but also for the immediately preceding states, known as at-risk mental states (ARMS) or ultra-high risk (UHR). These states would be fundamentally characterized by the concurrence of subclinical psychotic symptoms (SPS). While the scientific literature indicates that in people with UHR, abuse experiences are associated with more severe SPS and a higher rate of transition to psychosis, it is not yet clear whether there are specific associations between types of maltreatment (physical, emotional, or sexual abuse and physical or emotional neglect) and kinds of SPS (positive and negative). While some studies argue for the non-specificity of the consequences of trauma, others would link some types of abuse to specific domains of SPS. The inconsistency of the data could be due to the fact that most studies do not consider the presence of post-traumatic symptoms that could arise from abuse situations. Additionally, studies with ARMS populations normally take into account very high-risk populations, usually patients who attend early care services, who have many more risk factors and a higher and more homogeneous levels of both trauma and SPS. Considering these limitations and trying to overcome them, this study intends to explore the relationships between types of abuse, post-traumatic symptomatology and types of SPS with young people who attend a day hospital and who make up a more heterogeneous clinical sample. The deeper knowledge about the relationship between childhood trauma associated with maltreatment and SPS that comes from this study could provide victimization profiles associated with types of SPS that could help improve both early detection and intervention.
