Impact of rurality and substance use on young people at ultra high risk for psychosis.

BACKGROUND: Longitudinal research into early intervention for youth at ultra high risk (UHR) for psychosis demonstrates beneficial outcomes including increased treatment compliance and greater participation in education and the workforce. Despite known barriers for rural youth accessing mental health services, research comparing urban and rural UHR youth is lacking. The study included an examination of the impact of substance use on functioning of UHR youth. METHODS: Youth aged 12 to 25 years were recruited from the urban area of Newcastle or the rural area of Orange, New South Wales, Australia, and identified as UHR by the Comprehensive Assessment of At Risk Mental States. Rural and urban youth were compared on clinical profiles, social and occupational functioning and substance use. RESULTS: The rural youth showed different help-seeking behaviours and had greater functional impairment than urban youth. Substance use was common across the sample of 57 youth (mean age 16.5 years, 56% female) and a history of hazardous substance use was associated with higher levels of depression. Rural youth (n = 32) were more likely than urban youth to be taking antidepressants at baseline (44% compared with 16%). CONCLUSION: Different patterns of help seeking by rural UHR youth suggest a need for greater access to psychosis informed primary care early intervention services. Interventions should target functional decline to prevent adverse outcomes such as reduced community participation and unemployment. In addition, interventions for substance use should be a priority for UHR youth, who should also be screened and monitored for depressive symptoms and treated for depression if indicated.

A randomised controlled trial of cognitive behaviour therapy versus non-directive reflective listening for young people at ultra high risk of developing psychosis: The detection and evaluation of psychological therapy (DEPTh) trial.

BACKGROUND: Intervention trials for young people at ultra high risk (UHR) for psychosis have shown cognitive behaviour therapy (CBT) to have promising effects on treating psychotic symptoms but have not focused on functional outcomes. We hypothesized that compared to an active control, CBT would: (i) reduce the likelihood of, and/or delay, transition to psychosis; (ii) reduce symptom severity while improving social functioning and quality of life, whether or not transition occurred. METHOD: This was a single-blind randomised controlled trial for young people at UHR for psychosis comparing CBT to an active control condition, Non Directive Reflective Listening (NDRL), both in addition to standard care, with a 6month treatment phase and 12months of follow-up. Statistical analysis is based on intention-to-treat and used random effect models to estimate treatment effects common to all time-points. RESULTS: Fifty-seven young people (mean age=16.5years) were randomised to CBT (n=30) or NDRL (n=27). Rate of transition to psychosis was 5%; the 3 transitions occurred in the CBT condition (baseline, 2months, 5months respectively). The NDRL condition resulted in a significantly greater reduction in distress associated with psychotic symptoms compared to CBT (treatment effect=36.71, standard error=16.84, p=0.029). There were no significant treatment effects on frequency and intensity of psychotic symptoms, global, social or role functioning. CONCLUSION: Our sample was higher functioning, younger and experiencing lower levels of psychotic like experiences than other trials. The significantly better treatment effect of NDRL on distress associated with psychotic symptoms supports the recommendations for a stepped-care model of service delivery. This treatment approach would accommodate the younger UHR population and facilitate timely intervention. TRIAL REGISTRATION: ANZCTR 12606000101583.
