Early detection and intervention of psychosis in children and adolescents: urgent need for studies
Gender differences in first episode psychotic mania
Background : The aim of this paper was to delineate the impact of gender on premorbid history, onset, and 18 month outcomes of first episode psychotic mania (FEPM) patients. Methods : Medical file audit assessment of 118 (male = 71; female = 47) patients with FEPM aged 15 to 29 years was undertaken on clinical and functional measures. Results : Males with FEPM had increased likelihood of substance use (OR = 13.41, p < .001) and forensic issues (OR = 4.71, p = .008), whereas females were more likely to have history of sexual abuse trauma (OR = 7.12, p = .001). At service entry, males were more likely to be using substances, especially cannabis (OR = 2.15, p = .047), had more severe illness (OR = 1.72, p = .037), and poorer functioning (OR = 0.96, p = .045). During treatment males were more likely to decrease substance use (OR = 5.34, p = .008) and were more likely to be living with family (OR = 4.30, p = .009). There were no gender differences in age of onset, psychopathology or functioning at discharge. Conclusions : Clinically meaningful gender differences in FEPM were driven by risk factors possibly associated with poor outcome. For males, substance use might be associated with poorer clinical presentation and functioning. In females with FEPM, the impact of sexual trauma on illness course warrants further consideration
Incentive motivation in first-episode psychosis: A behavioural study
<p>Abstract</p> <p>Background:</p> <p>It has been proposed that there are abnormalities in incentive motivational processing in psychosis, possibly secondary to subcortical dopamine abnormalities, but few empirical studies have addressed this issue.</p> <p>Methods:</p> <p>We studied incentive motivation in 18 first-episode psychosis patients from the Cambridge early psychosis service CAMEO and 19 control participants using the Cued Reinforcement Reaction Time Task, which measures motivationally driven behaviour. We also gathered information on participants' attentional, executive and spatial working memory function in order to determine whether any incentive motivation deficits were secondary to generalised cognitive impairment.</p> <p>Results:</p> <p>We demonstrated the anticipated "reinforcement-related speeding" effect in controls (17 out of 19 control participants responded faster during an "odd-one-out" task in response to a cue that indicated a high likelihood of a large points reward). Only 4 out of 18 patients showed this effect and there was a significant interaction effect between reinforcement probability and diagnosis on reaction time (F<sub>1,35 </sub>= 14.2, p = 0.001). This deficit was present in spite of preserved executive and attentional function in patients, and persisted even in antipsychotic medication free patients.</p> <p>Conclusion:</p> <p>There are incentive motivation processing abnormalities in first-episode psychosis; these may be secondary to dopamine dysfunction and are not attributable to generalised cognitive impairment.</p

Few studies have considered the geographical accessibility of services in relation to treatment delay in early
psychosis. To address this, we investigated whether treatment delay is co-determined by straight-line distance
to hospital based specialist services in a mainly rural mental health context.
Methods: A naturalistic cross-sectional study was conducted among a sample of recent onset psychosis patients
in northern Norway (n = 62). Data on patient and service related determinants were analysed.
Results: Half of the cohort had a treatment delay longer than 4.5 months. In a binary logistic regression model,
straight-line distance was found to make an independent contribution to delay in which we controlled for other
known risk factors.
Conclusions: The determinants of treatment delay are complex. This study adds to previous studies on treatment
delay by showing that the spatial location of services also makes an independent contribution. In addition, it may
be that insidious onset is a more important factor in treatment delay in remote areas, as the logistical implications of
specialist referral are much greater than for urban dwellers. The threshold for making a diagnosis in a remote location
may therefore be higher. Strategies to reduce the duration of untreated psychosis in rural areas would benefit from
improving appropriate referral by crisis services, and the detection of insidious onset of psychosis in community based
specialist services
Clinical and cost-effectiveness of contingency management for cannabis use in early psychosis: the CIRCLE randomised clinical trial
Background
Cannabis is the most commonly used illicit substance among people with psychosis. Continued cannabis use following the onset of psychosis is associated with poorer functional and clinical outcomes. However, finding effective ways of intervening has been very challenging. We examined the clinical and cost-effectiveness of adjunctive contingency management (CM), which involves incentives for abstinence from cannabis use, in people with a recent diagnosis of psychosis.
Methods
CIRCLE was a pragmatic multi-centre randomised controlled trial. Participants were recruited via Early Intervention in Psychosis (EIP) services across the Midlands and South East of England. They had had at last one episode of clinically diagnosed psychosis (affective or non-affective); were aged 18 to 36; reported cannabis use in at least 12 out of the previous 24 weeks; and were not currently receiving treatment for cannabis misuse, or subject to a legal requirement for cannabis testing. Participants were randomised via a secure web-based service 1:1 to either an experimental arm, involving 12 weeks of CM plus a six-session psychoeducation package, or a control arm receiving the psychoeducation package only. The total potential voucher reward in the CM intervention was £240. The primary outcome was time to acute psychiatric care, operationalised as admission to an acute mental health service (including community alternatives to admission). Primary outcome data were collected from patient records at 18 months post-consent by assessors masked to allocation. The trial was registered with the ISRCTN registry, number ISRCTN33576045.
Results:
551 participants were recruited between June 2012 and April 2016. Primary outcome data were obtained for 272 (98%) in the CM (experimental) group and 259 (95%) in the control group. There was no statistically significant difference in time to acute psychiatric care (the primary outcome) (HR 1.03, 95% CI 0.76, 1.40) between groups. By 18 months, 90 (33%) of participants in the CM group, and 85 (30%) of the control groups had been admitted at least once to an acute psychiatric service. Amongst those who had experienced an acute psychiatric admission, the median time to admission was 196 days (IQR 82, 364) in the CM group and 245 days (IQR 99,382) in the control group. Cost-effectiveness analyses suggest that there is an 81% likelihood that the intervention was cost-effective, mainly resulting from higher mean inpatient costs for the control group compared with the CM group, however the cost difference between groups was not statistically significant. There were 58 adverse events, 27 in the CM group and 31 in the control group.
Conclusions
Overall, these results suggest that CM is not an effective intervention for improving the time to acute psychiatric admission or reducing cannabis use in psychosis, at least at the level of voucher reward offered
Diagnóstico diferencial de primeiro episódio psicótico: importância da abordagem otimizada nas emergências psiquiátricas
From Psychopharmacological Evidence to Clinical Practice: Unmet Needs in Child & Adolescent Psychiatry – Reflections on Kölch & Plener (2016)
Modulare Psychotherapie im Kindes- und Jugendalter
Zusammenfassung. Die Implementierung evidenzbasierter Psychotherapieprogramme für Kinder und Jugendliche in die klinische Praxis ist bislang nur unzureichend gelungen. Ein wesentlicher Grund dafür ist, dass Patienten im klinischen Versorgungskontext deutlich mehr komorbide Störungen und häufiger wechselnde Therapieziele aufweisen als Patienten im Forschungskontext. Folglich erscheinen modulare Psychotherapieprogramme vielversprechend, da sie eine flexible Anpassung der vorhandenen evidenzbasierten Behandlungsprogramme an die individuellen Therapiebedürfnisse des jeweiligen Patienten erlauben. Da bislang noch keine Übersichtsarbeit zu modularen Therapieansätzen für die Behandlung von Kindern und Jugendlichen vorliegt, wurde eine systematische Literaturrecherche durchgeführt. Die Ergebnisse der 15 eingeschlossenen randomisierten klinischen Studien sprechen dafür, dass Kinder und Jugendliche, die modulare Psychotherapie erhielten, im Vergleich zu Kontrollbedingungen nach Therapieende signifikant weniger Symptomatik zeigten und seltener die Diagnosekriterien für das jeweilige Störungsbild erfüllten. Aufgrund der unzureichenden Forschungslage müssen künftige Studien die inkrementelle Wirksamkeit dieser modularen Ansätze sowie die Gültigkeit der ihnen zugrunde liegenden theoretischen Modelle und Entscheidungsalgorithmen untersuchen. Modulare Therapieprogramme könnten einen wesentlichen Beitrag zur Entwicklung und Implementierung einer personalisierten und therapieschulenübergreifenden, evidenzbasierten Psychotherapie für Kinder und Jugendliche leisten.
