Study information

Scientific title


Study hypothesis

To develop a brief Enhanced Relapse Prevention (ERP) for people with Bipolar Disorder which can be offered by Care Co-ordinators (CCs) in the NHS and to gather specific information required to inform the design of a large multi-site trial to test its effectiveness in comparison to treatment as usual.
1. To devise a manual for brief Enhanced Relapse Prevention (ERP)
2. To refine a methodology to train (CCs) in ERP
3. To assess the effectiveness of the training package by assessing CC skills
4. To gain feedback form CCs receiving training in order to identify barriers and solutions in offering such training in a large trial
5. To calculate an estimate of the relationship of between to within cluster variance needed to design a cluster RCT for ERP
6. To compare outcome of patients receiving ERP and those receiving treatment as usual to estimate the effect size of the intervention
7. To estimate rates of recruitment and dropout for a large trial of this intervention
8. To gain feedback from people receiving the intervention in order to identify barriers and solutions to offering this intervention in a large trial

Bipolar Disorder (Type I and II)


ERP versus TAU

1. A training package for ERP delivered to CCs who are part of Community Mental Health Teams (CMHTs) and who have current active caseloads of people with BD. The training will include theoretical background and rationale for the approach, detailed analysis of the content of each session in the manual and videoed role play using trained actors. Written materials will accompany all aspects of training, and will take place over six 2-h sessions.
2. Following training, CCs will offer ERP to patients who have a diagnosis of BD. This involves patients and CCs working together to identify prodromal signs of manic and depressive relapse separately and developing and rehearsing an action plan for responding to such signs.

As of 14/02/2007: Please note that the anticipated end date of this trial has been extended to 20/01/2007.

Primary outcome measures

1. The effectiveness of the training intervention with CCs assessed by training and CC ratings
2. An estimate of the effect size of the ERP intervention by CCs will be made by comparing patients receiving ERP with those receiving treatment as usual on:
a. Time to recurrence to an episode of illness of sufficient severity to reach Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for major depressive, manic, or mixed episode, based on the Structured Clinical Interview for Depression (SCID) interview
b. Assessment of coping using the Coping with Manic and Depressive Prodromes checklist
c. The Client Service Receipt Schedule (CSRI) to estimate the use of primary, inpatient, outpatient, day patient, community and emergency services

The feasibility will be assessed using quantitative and qualitative data.

Quantitative data:
1. Recruitment rates of CMHTs: proportion of teams approached who agreed to take part
2. Attendance rates: the number of training and supervision sessions attended by each care coordinator
3. Care coordinator feedback ratings of training and supervision
4. Service user recruitment rates: number of service users recruited within each group - ERP and TAU
5. Service user retention rates: number of service users that completed follow-up at each point
6. Number of relatives taking part (ERP only)

Qualitative data:
1. Interview feedback from care coordinators (ERP and TAU)
2. Feedback from service users and relatives (ERP only) identifying barriers to the intervention.

An estimate of the effect size of the intervention will be made using time from baseline to recurrence of an episode of major depression , hypomania, mania, or mixed, satisfying DSM-IV criteria, as the main outcome. All outcomes will be reported allowing for design effect.

Secondary outcome measures

1. Longitudinal analysis of symptom severity using the Longitudinal Interval Follow-up Evaluation (LIFE-II) modified to DSM criteria
2. An estimate of recruitment and drop-out rates
3. Qualitative interviews to gather detailed information from CCs of their experience of training and offering ERP, and from patients with BD and their friends/relatives of their experience of therapy
