The detection of individuals at clinical ultra-high risk for psychosis (CHR-P) may be a key limiting step for early interventions, and there is some uncertainty regarding the true clinical reliability of the CHR-P states. The aim of this study was to explore how practitioners who were in the direct treatment of children with psychiatric disorders [child psychiatry specialists/trainees (n = 227, n = 131), adult psychiatrists (n = 27), and child neurologists (n = 2)] perceive the DSM-5-Attenuated Psychosis Syndrome (DSM-5-APS), and their clinical routine practice in the treatment of it. Three vignettes describing fictional cases presented with symptoms of either DSM-5-Schizophrenia, DSM-5-APS, and no psychotic symptoms were created. We asked these practitioners to apply a DSM-5 diagnosis and to choose appropriate treatment(s) for these vignettes. Of the responders, 43% correctly diagnosed the APS vignette, whereas 37.4% mentioned that it had a full-blown psychotic episode. Regarding the therapeutic approach for the APS vignette, 72.1% of all practitioners chose a psychopharmacological intervention and 32% individual psychotherapy. This study showed that the diagnostic inter-rater reliability of the DSM-5-APS among child/adolescent mental health practitioners was consistent with the results from the DSM-5 field trials (Kappa = 0.46). Moreover, almost three in four practitioners endorsed psychopharmacological intervention as a treatment option for the DSM-5-APS case. The lack of evidence of psychopharmacological interventions in CHR-P situations emphasizes that the least harmful interventions should be recommended. Thus, our findings indicated a need for raising awareness regarding the CHR-P paradigm and its treatment as well as the development of solid guidelines that can be implemented in clinical practice.

In both clinical practice and research, focus has gradually shifted in the past decade from clinical psychosis to recognition of attenuated psychosis syndromes and the development of interventions which can prevent or mitigate transition from prodromal states to the clinical end of the spectrum. The attenuated psychosis syndromes (APS) is an entity in DSM-5 characterized by the presence of delusions, hallucinations, or disorganized speech in an attenuated form not better explained by another DSM-5 diagnosis. There is a dearth of literature on the APS in African populations, with a search of existing literature revealing no definitive prevalence study. However, in a Nigerian sample, as much as one in five adolescent students screened positive for APS. Nevertheless, a shortage of specialized services, pervasive stigma, and a preference for alternative pathways to care have militated against adequate care of adolescents with APS. Very few assessment tools have been validated for use in African populations, and intervention strategies are hampered by a shortage of trained personnel. An illustrative case is presented of an adolescent whose initial presentation was in keeping with APS but thereafter progressed to clinical psychosis. The case highlights aspects of presentation in a specialized service in Nigeria, as well as some of the problems and prospects in management of such cases.

Objective: This study aimed to investigate the relationship between prodromal psychotic symptoms and psychological distress among Nigerian adolescents.Method: Students (n = 508) were randomly selected from secondary schools in Abeokuta, Nigeria. A socio-demographic questionnaire, the Prodromal Questionnaire-Brief Version (PQ-B) and the Strengths and Difficulties Questionnaire (SDQ) were administered to each student.Results: The mean age of the students was 15.4 years (SD 1.3), with most (63%) being female. More than half (55.3%) reported having had a lifetime experience of major life event (20.9% in the preceding 6 months) while 13.9% had experienced bullying or abuse (5.1% in the preceding 6 months). The prevalence of prodromal symptoms was 20.9% (95% CI 0.174–0.244). Abnormal scores in emotional and conduct problems were seen in 11.8% and 6% respectively, while 7.3% had abnormal scores in each of the hyperactivity and peer problems subscales of the SDQ. Abnormality in prosocial behaviour was found in 1.8% of students, with overall abnormality in 4.9%. Regression analysis showed that prodromal symptoms were predicted by female sex, lifetime and 6 month history of major life event, and lifetime and 6 month history of bullying or abuse. Prodromal symptoms were also predicted by higher total SDQ scores and higher scores in all domains of psychological distress except the prosocial domain.Conclusion: The study showed a relationship between reported prodromal symptoms and the occurrence of psychological distress. It also showed that early childhood trauma may be a predisposing factor to the early stages of development of psychosis, with female children being especially prone in the years of adolescence.
