BackgroundRecent community-based research has suggested that psychotic experiences act as markers of severity of psychopathology. There has, however, been a lack of clinic-based research. We wished to investigate, in a clinical sample of adolescents referred to a state-funded mental health service, the prevalence of (attenuated or frank) psychotic experiences and the relationship with (i) affective, anxiety and behavioural disorders, (ii) multimorbid psychopathology, (iii) global functioning, and (iv) suicidal behaviour.MethodThe investigation was a clinical case–clinical control study using semi-structured research diagnostic psychiatric assessments in 108 patients newly referred to state adolescent mental health services.ResultsPsychotic experiences were prevalent in a wide range of (non-psychotic) disorders but were strong markers of risk in particular for multimorbid psychopathology (Z = 3.44, p = 0.001). Young people with psychopathology who reported psychotic experiences demonstrated significantly poorer socio-occupational functioning than young people with psychopathology who did not report psychotic experiences, which was not explained by multimorbidity. Psychotic experiences were strong markers of risk for suicidal behaviour. Stratified analyses showed that there was a greatly increased odds of suicide attempts in patients with a major depressive disorder [odds ratio (OR) 8.89, 95% confidence interval (CI) 1.59–49.83], anxiety disorder (OR 15.4, 95% CI 1.85–127.94) or behavioural disorder (OR 3.13, 95% CI 1.11–8.79) who also had psychotic experiences compared with patients who did not report psychotic experiences.ConclusionsPsychotic experiences (attenuated or frank) are an important but under-recognized marker of risk for severe psychopathology, including multimorbidity, poor functioning and suicidal behaviour in young people who present to mental health services.

BackgroundPsychotic symptoms in the context of psychiatric disorders are associated with poor functional outcomes. Environmental stressors are important in the development of psychosis; however, distress may only be pathogenic when it exceeds an individual’s ability to cope with it. Therefore, one interesting factor regarding poor functional outcomes in patients with psychotic symptoms may be poor coping. This paper aimed to address the question whether 1) psychotic symptoms are associated with poorer functioning and 2) whether poor coping moderated the association.MethodsIn a clinical case-clinical control study of 106 newly-referred adolescent patients with non-psychotic psychiatric disorders, coping was investigated using the Adolescents Coping Scale. Severity of impairment in socio-occupational functioning was assessed with the Children’s Global Assessment Scale.ResultsPatients with non-psychotic psychiatric disorders and additional psychotic symptoms (N = 50) had poorer functioning and were more likely to use avoidance-oriented coping compared to patients with non-psychotic psychiatric disorders without psychotic symptoms (N = 56). No differences were found with respect to approach-oriented coping. When stratifying for poor/good coping, only those adolescent patients with psychotic symptoms who applied poor coping (i.e. less use of approach-oriented coping styles [OR 0.24, p < 0.015] and more use of avoidance-oriented coping [OR 0.23, p < 0.034]) had poorer functioning. However, these interactions were not significant.ConclusionsNon-adaptive coping and poorer functioning were more often present in adolescents with non-psychotic psychiatric disorders and additional psychotic symptoms. Due to small subgroups, our analyses could not give definitive conclusions about the question whether coping moderated the association between psychotic symptoms and functioning. Improvement of coping skills may form an important target for intervention that may contribute to better clinical and functional outcomes in patients with psychotic symptoms.

This study involved a detailed standardized initial research assessment which was carried out with 100 young people aged 12-15 years newly referred to a child and adolescent mental health service. The assessment involved the K-SADS interview with the young person and their parent, the Strengths and Difficulties Questionnaire, the Clinical Global Impression Scale, and the Children's Global Assessment Scale. Diagnoses resulting from these 'research assessments' were compared with clinical diagnoses, which were determined by case note analysis and discussion with the key clinician. Results showed that a clinical diagnosis of depressive disorder was made in only one-third of those who received a 'research assessment' diagnosis of depressive disorder, and suicidality was missed in a significant proportion of cases. Those with a diagnosis of depressive disorder had significantly more problems, more comorbidity, more suicidality and greater functional impairment than those without. It is important to keep depression and suicidality in mind when assessing young people with complex mental health difficulties. Unless specific pointers are sought, it is easy to miss these, which may mean that vulnerable young people do not benefit from potentially effective treatments.

Parents of newly-born twins regardless of the mode of conception should be considered an at risk group for parental distress. Support groups such as the Twins and Multiple Births Association could be important in providing that crucial social interaction and support that seems to be important in the emotional well-being of parents of twins.
