Résumé (Abstract) Background: Psychotic symptoms (PS) are associated with increased multimorbidity and higher rates of suicidal thoughts and behaviors (STBs). However, research examining the relationship between PS and STBs among adolescent inpatients is scarce. This study aims to address this gap by investigating PS and STBs prevalence in an adolescent psychiatric unit, and their evolution during hospitalization, across three diagnostic groups: Group 1 for schizophrenia spectrum disorders; Group 2 for affective disorders presenting psychotic symptoms; and Group 3 for patients without psychotic features. Additionally, it aims to explore the link between PS and STBs in non-psychotic inpatients.

Methods: Data from 948 adolescents admitted to a psychiatric unit between 2014 and 2022 were analyzed. PS, STBs, and other psychopathological variables were assessed by clinicians at intake and discharge using the Health of The Nation Outcome Scale for Children and Adolescents (HoNOSCA). Patients were classified into the three groups based on their ICD-10 diagnosis at discharge.

Results: Groups 1 and 2 displayed high rates of PS, while Groups 2 and 3 showed elevated rates of STBs. Within the non-psychotic group, a significant positive association between PS and STBs was observed at intake, even when considering confounding variables (i.e., socio-demographics and comorbid problems). Additionally, heightened STBs upon admission predicted greater reduction in PS over the course of hospitalization.

Conclusions: These findings highlight the interplay between PS and STBs among non-psychotic adolescent inpatients, suggesting the importance of assessing these dimensions in this population, which could potentially enhance care strategies.
