Conditions: Schizophrenia; Bipolar Disorder; Major Depression

Summary: severe mental illness such as schizophrenia and mood disorders typically develops at a young age and can cause life-long disability. currently available treatments cannot cure severe mental illness. this makes it important to find ways to prevent severe mental illness in young people before it has a chance to develop. this research study will pilot a new preventive intervention for young people who are at high risk of developing severe mental illness. the investigators will target early preceding factors (the 'antecedents') to severe mental illness which includes anxiety, unusual hearing and visual experiences, the loss of previously acquired abilities, and sudden and unpredictable changes in mood. these antecedents strongly predict an increased risk of developing severe mental illness. they are often impairing and distressing to the individual but can be improved with self-management skills and parent training, and they are present in the individual years before the onset of severe mental illness which makes them an ideal target for early intervention. the goal is to intervene early enough in the young person's life that severe mental illness can be prevented, hopefully leading to a happy, healthy and productive adulthood. the investigators want to test the acceptability and short-term efficacy of this new preventive intervention.

the proposed research will test the acceptability and efficacy of an early preventive intervention for the antecedents to severe mental illness with the following hypotheses: 1. do young people at risk for severe mental illness accept a cognitive-behavioural intervention that targets early antecedents to severe mental illness? 2. does a cognitive-behavioural intervention targeting antecedents to severe mental illness reduce the rate of unusual auditory and visual experiences, the loss of previously acquired abilities, anxiety, and unstable mood? 3. does a cognitive-behavioural intervention focused on antecedents reduce emotional distress in young people at risk for severe mental illness? 4. is social functioning improved in young people at risk for severe mental illness through antecedent-focused cognitive-behavioural intervention? 5. (long-term) does early cognitive-behavioural intervention targeting antecedents reduce the risk of developing severe mental illness? design: the investigators are proposing to test a new preventive intervention for antecedent conditions for which most individuals would currently receive no intervention at all. therefore, the best comparison for the proposed intervention is a group of individuals who do not differ from the intervention group at baseline but who are neither offered a specific intervention nor discouraged from seeking any treatment that they may normally receive. such a non-intervention comparison group is best achieved using the recently-developed cohort-multiple randomized controlled design (cmrct; relton et al., 2010) in a cmrct, eligible participants are identified within a cohort study, which follows up all participants and measures outcomes of interest. a proportion of eligible participants within the cohort is randomly selected and approached to be offered the intervention of interest, while the other eligible participants in the cohort are not so approached (i.e., controls). all participants continue to be followed up as part of the cohort irrespective of whether they accept the offered intervention or not. this enables a more realistic, fair and complete evaluation of the intervention effects. those randomly selected to be offered macbt will be approached, given full information about the planned intervention and asked to provide a separate written consent for the intervention study. intervention: multimodal antecedent-focussed cognitive-behavioural training (macbt). this integrated model focuses on normalisation of the unusual experiences, their re-appraisal, exploring helpfulness of current coping, and developing a repertoire of strategies to decrease the impact of these experiences on the young person's life. the macbt follows a manual describing obligatory and optional therapeutic elements, proposed list of modules, outline of a therapeutic session, and the integrated cognitive model. the model and techniques are adapted to an age range of 9 to 17 years, with more visual material and child friendly language options for the younger part of the age range (9-12) and more teen-relevant and interpersonal content options for the older part of the age range (13-17). the intervention will be delivered in 8 to 16 one-hour sessions in an individual format. sessions will be initially weekly, and then spaced out to once every two weeks in the latter stages of the intervention.
