ItemBroad clinical high-risk mental state (CHARMS): Methodology of a cohort study validating criteria for pluripotent risk(WILEY, 2019-06)AIM: The development of the ultra-high risk (UHR) criteria for psychosis created a new paradigm for the prevention research in psychiatry. Since (1) prevention research faces the challenge of achieving adequate statistical power when focusing on single low-incidence syndromes and (2) early clinical phenotypes are overlapping and non-specific, this study broadens the UHR state beyond psychosis as an outcome. The CHARMS (clinical high at-risk mental state) study aims to prospectively validate a set of trans-diagnostic criteria to identify help-seeking young people at risk of developing a range of serious mental illnesses. METHODS: This paper describes the methodology of the CHARMS study, which involves applying the CHARMS criteria to a cohort of help-seeking young people aged 12 to 25 attending youth mental health services in Melbourne. New referrals meeting the CHARMS criteria are allocated to the CHARMS+ group; referrals not meeting CHARMS threshold are allocated to CHARMS- group (control group); referrals meeting criteria for a full-threshold disorder are excluded. Transition status and clinical and functional outcomes are re-assessed at 6 and 12 months. CONCLUSIONS: This study will be the first to introduce and validate clinical criteria to identify a broader at-risk patient population, which may facilitate young people's access to clinical services and early treatment by reducing the reliance on "caseness" defined according to current diagnostic categories being required for service entry. These criteria may introduce a new, trans-diagnostic approach for understanding risk factors and pathogenic mechanisms that drive the onset of severe mental illness and the next generation of preventive intervention trials.

ItemA systematic review and meta-analysis of prospective transition from major depression to bipolar disorder(WILEY, 2017-04)OBJECTIVE: Some people with major depressive disorder (MDD) may be at a pre-onset stage for bipolar disorder (BD), where early identification or prevention efforts may be feasible. We aimed to identify rates and characteristics predictive of transition to BD in prospective follow-up studies of people with MDD. METHODS: Using a systematic search strategy, we identified studies with a diagnostic ascertainment of MDD and BD of an adequate standard, and where the minimum length of follow-up was 6 months. We examined the incidence and point prevalence of BD and the pooled odds ratios (OR) for baseline predictors. RESULTS: From 5554 unique publications, 56 were included. Nearly a quarter of adults (22.5%) and adolescents with MDD followed up for a mean length of 12-18 years developed BD, with the greatest risk of transition being in the first 5 years. The meta-analysis identified that transition from MDD to BD was predicted by family history of BD (OR = 2.89, 95% CI: 2.01-4.14, N = 7), earlier age of onset of depression (g = -0.33, SE = 0.05, N = 6) and presence of psychotic symptoms (OR = 4.76, 95% CI: 1.79-12.66, N = 5). CONCLUSIONS: Participants with the identified risk factors merit closer observation and may benefit from prevention efforts, especially if outcomes broader than BD are considered.

ItemIntegrating family work into the treatment of young people with severe and complex depression: a developmentally focused model(WILEY, 2018-04)AIM: Although models of family intervention are clearly articulated in the child and early adolescent literature, there is less clarity regarding family intervention approaches in later adolescence and emerging adulthood. METHODS: This study provides the rationale and intervention framework for a developmentally sensitive model of time-limited family work in the outpatient treatment of complex youth depression (15-25 years). RESULTS: Derived from current practice in the Youth Mood Clinic (YMC) at Orygen Youth Health, Melbourne, a stepped model of family intervention is discussed. YMC aims to provide comprehensive orientation, assessment and education to all families. For some, a family-based intervention, delivered either by the treating team or through the integration of a specialist family worker, offers an important adjunct in supporting the recovery of the young person. Developmental phases and challenges experienced by the young person with respect to family/caregiver involvement are discussed in the context of two case studies. CONCLUSIONS: A developmentally sensitive model is presented with particular attention to the developmental needs and preferences of young people. Formal evaluation of this model is required. Evaluation perspectives should include young people, caregivers, the broader family system (i.e. siblings) and the treating team (i.e. case manager, doctor and family worker) incorporating outcome measurement. Such work determines how best to apply a time-limited family-based intervention approach in strengthening family/caregiver relationships as part of the young person's recovery from severe and complex depression.

ItemModerated online social therapy for depression relapse prevention in young people: pilot study of a "next generation' online intervention(WILEY, 2018-08)AIM: Implementation of targeted e-mental health interventions offers a promising solution to reducing the burden of disease associated with youth depression. A single-group pilot study was conducted to evaluate the acceptability, feasibility, usability and safety of a novel, moderated online social therapy intervention (entitled Rebound) for depression relapse prevention in young people. METHODS: Participants were 42 young people (15-25 years) (50% men; mean age = 18.5 years) in partial or full remission. Participants had access to the Rebound platform for at least 12 weeks, including the social networking, peer and clinical moderator and therapy components. RESULTS: Follow-up data were available for 39 (92.9%) participants. There was high system usage, with 3034 user logins (mean = 72.2 per user) and 2146 posts (mean = 51.1). Almost 70% of users had ≥10 logins over the 12 weeks, with 78.5% logging in over at least 2 months of the pilot. A total of 32 (84%) participants rated the intervention as helpful. There was significant improvement between the number of participants in full remission at baseline (n = 5; none of whom relapsed) relative to n = 19 at 12-week follow-up (P < 0.001). Six (14.3%) participants relapsed to full threshold symptoms at 12 weeks. There was a significant improvement to interviewer-rated depression scores (Montgomery-Asberg Depression Rating Scale (MADRS); P = 0.014, d = 0.45) and a trend for improved strength use (P = 0.088, d = 0.29). The single-group design and 12-week treatment phase preclude a full understanding of the clinical benefits of the Rebound intervention. CONCLUSIONS: The Rebound intervention was shown to be acceptable, feasible, highly usable and safe in young people with major depression.

ItemEthical considerations in preventive interventions for bipolar disorder(WILEY, 2017-04)AIM: Early intervention and prevention of serious mental disorders such as bipolar disorder has the promise of decreasing the burden associated with these disorders. With increasing early and preventive intervention efforts among cohorts such as those with a familial risk for bipolar disorder, there is a need to examine the associated ethical concerns. The aim of this review was to examine the ethical issues underpinning the clinical research on pre-onset identification and preventive interventions for bipolar disorder. METHODS: We undertook a PubMed search updated to November 2014 incorporating search terms such as bipolar, mania, hypomania, ethic*(truncated), early intervention, prevention, genetic and family. RESULTS: Fifty-six articles that were identified by this method as well as other relevant articles were examined within a framework of ethical principles including beneficence, non-maleficence, respect for autonomy and justice. The primary risks associated with research and clinical interventions include stigma and labelling, especially among familial high-risk youth. Side effects from interventions are another concern. The benefits of preventive or early interventions were in the amelioration of symptoms as well as the possibility of minimizing disability, cognitive impairment and progression of the illness. Supporting the autonomy of individuals and improving access to stigma-free care may help moderate the potential challenges associated with the risks of interventions. CONCLUSIONS: Concerns about the risks of early identification and pre-onset interventions should be balanced against the potential benefits, the individuals' right to choice and by improving availability of services that balance such dilemmas.

ItemImproving functional outcomes in early-stage bipolar disorder: The protocol for the REsearch into COgnitive and behavioural VERsatility trial(WILEY, 2019-12)AIM: Young people with bipolar disorder (BD) commonly experience reduced quality of life, persistent symptoms and impaired functional recovery despite often superior school performance. Compromised long-term functioning can ensue. There is evidence that psychological therapies alongside pharmacology may be more efficacious earlier in the course of the disorder. Intervention in the early stages may thus reduce the burden and risk associated with BD and mitigate the impact of the disorder on normal developmental trajectories. To date, however, the availability of evidence-based psychological therapies for young people with early BD is limited. Furthermore, there are no large-scale randomized controlled trials (RCTs) of such interventions. METHODS: The study is a prospective, single-blind, RCT examining the effectiveness of an adjunctive individualized and manualized psychological intervention, compared with treatment as usual within youth-specific early intervention services. The REsearch into COgnitive and behavioural VERsatility (RECOVER) intervention is delivered over a 6-month period. About 122 young people in the early stages of BD-I (at least one manic episode in the previous 2 years, with no more than five lifetime treated/untreated manic or hypomanic episodes) will be recruited. The assessments will occur at baseline, 3, 6 (primary endpoint, end of treatment), 9, 12, 15 and 18 months. RESULTS: Recruitment will commence in January 2019 and is anticipated to occur over a 3.5-year period. CONCLUSIONS: To date, there are no evidence-based psychological therapies tailored to young people with early BD. We will test whether early psychological intervention in the course of BD can reduce the symptomatic, psychological, vocational and social impacts that are seen in entrenched disorder.

ItemAripiprazole compared with placebo for auditory verbal hallucinations in youth with borderline personality disorder: Protocol for the VERBATIM randomized controlled trial(WILEY, 2019-12)AIM: Up to half of patients with borderline personality disorder report auditory verbal hallucinations that are phenomenologically indistinguishable from those in schizophrenia, occur early in the course of the disorder, and are enduring, distressing and disabling. In clinical practice, this symptom is widely assumed to be unresponsive to treatment with antipsychotic medication and early intervention is rarely offered. The Verbal Experiences Response in Borderline personality disorder to Aripiprazole TrIal Medication (VERBATIM) study aims to be the first controlled trial to investigate the effectiveness of conventional pharmacotherapy for this symptom in this patient group. METHOD: VERBATIM is a 12-week, triple-blind, single-centre, parallel groups randomised controlled trial, with a 27-week follow-up period. Participants between the ages of 15 and 25 years receive either aripiprazole or placebo daily, commencing at 2 mg and increasing to 10 mg by day 15. Further dose escalations (up to 30 mg) may occur, as clinically indicated. This trial was prospectively registered with the Australian and New Zealand Clinical Trials Registry ACTRN12616001192471 on 30/08/2016. RESULTS: The primary outcome is severity of auditory verbal hallucinations assessed using the Psychotic Symptom Rating Scale. Secondary outcomes include the severity of general psychopathology, borderline personality pathology, social and occupational functioning and change in brain resting state connectivity. The primary endpoint is week 12 and secondary endpoint is week 39. CONCLUSION: The results will inform treatment decisions for individuals with borderline personality disorder who present with auditory verbal hallucinations.

ItemFactors associated with vocational disengagement among young people entering mental health treatment(WILEY, 2019-08)AIM: Most mental disorders have their onset by age 25, disrupting normative vocational engagement. Factors associated with vocational disengagement at first contact with specialist treatment are important for service planning. The aim of this paper was to investigate the association between theoretically important factors and vocational disengagement for youth entering mental health treatment. METHODS: A file audit was used to extract vocational data of 145 young people aged 15 to 25 years entering treatment in 2011 at a public youth mental health service in Melbourne, Australia. Comparisons were made across three specialist programs for: psychosis (n = 50), mood disorders (n = 52) and borderline personality pathology (n = 43). Individual characteristics were entered into univariate and multivariate logistic regressions to investigate their associations with vocational disengagement. RESULTS: Educational disengagement was associated with being older (OR = 4.38, P = 0.004) and not living with parents (OR = 2.87, P = 0.038). Unemployment and being NEET (Not in Education, Employment or Training) were both associated with not having commenced tertiary education (OR = 0.23, P = 0.022; OR = 0.05, P = 0.002; respectively). Being NEET was also associated with being older (OR = 6.18, P = 0.004). Primary diagnostic grouping was not associated with vocational disengagement, once accounting for other factors. CONCLUSIONS: The likelihood of vocational disengagement did not differ across disorder groups, implying that intervention should be "transdiagnostic" and might best target education first, specifically post-secondary qualifications. Other domains or variables not measured in this study are also likely to be important, and this might include young people's support systems and symptom severity. Qualitative studies may be useful for exploring further factors relevant to vocational engagement.

ItemVocational engagement among young people entering mental health treatment compared with their general population peers(WILEY, 2019-06)AIM: To compare rates of vocational engagement for youth entering specialist mental health treatment with the general population. METHODS: A file audit retrieved vocational data for 145 youth aged 15 to 25 entering treatment. Clinical and population data were stratified by age and sex and compared between cohorts. RESULTS: Compared to the population, young people entering mental health treatment were less likely to have completed at least Year 11 in school (77% vs 42%, P < 0.001); and demonstrated higher rates of "Not in Education, Employment or Training" (9% vs 33%, P < 0.001). Individuals aged 15 to 18 years entering treatment experienced greater rates of educational disengagement than the population (30% vs 11%, P < 0.001), whereas people aged 19 to 25 years showed higher unemployment rates (52% vs 35%, P = 0.003). CONCLUSIONS: Youth entering specialist mental health treatment have marked levels of vocational disengagement compared to demographically-matched peers. Early vocational intervention for these young people is essential.

ItemA Comparison of Vocational Engagement Among Young People with Psychosis, Depression and Borderline Personality Pathology(SPRINGER, 2018-08)Poor vocational engagement is well documented among young people experiencing first-episode psychosis (FEP). The aim of the present study was to establish and compare rates of vocational engagement across young people with first-episode psychosis, depression, and borderline personality pathology. A file audit was used to collect vocational data of young people aged 15-25 entering tertiary mental health treatment in 2011. Rates of vocational engagement were similar across groups, indicating that like those with FEP, young people with depression and borderline personality pathology experience impaired vocational engagement and are in need of targeted vocational interventions. Post hoc analysis indicated that that the depression group had significantly more people who were partially vocationally engaged compared with the psychosis group, suggesting that vocational interventions might need to be targeted differently across different diagnostic groups. Future research should explore risk factors for vocational disengagement across diagnostic groups in order to inform intervention development.
