Description of intervention(s) / exposure
Interpersonal and Social Rhythm Therapy combined with Cognitive Remediation.
IPSRT (Frank, 2005) is an integrative psychotherapy combining interpersonal psychotherapy (Klerman and Weissman, 1982) which targets interpersonal stressors such as interpersonal conflicts, role transitions and losses; with social rhythms therapy (aimed at establishing regularity in life patters such as sleeping, eating and social contact to stabilise circadian patterns). Both elements aim to stabilise functioning to minimise recurrence of mood episodes. IPSRT will be delivered on an individual basis in the clinic according to a manualised protocol. IPSRT will involve weekly sessions for 10-12 weeks followed by fortnightly for approximately 8 sessions, and then approximately 4 monthly sessions for the rest of the 1 year duration of treatment (total approximately 24 sessions). If there is deterioration in the patient’s mood, they may be seen more regularly and will be coded “crisis”. Care will be taken to minimise variation around the total number of sessions between groups. All sessions will be audio-taped and randomly selected and rated to ensure adherence to therapy protocols. All therapists will participate in regular and ongoing supervision.
Patients in the CR arm will be introduced by their therapists to a computerised cognitive remediation package (provided free of charge by Scientific Brain Training Professional (SBT-pro) - www.scientificbraintrainingpro.com). This will begin between weeks 7-9 (after allowing time for engagement with the therapist) and will continue at the 8 fortnightly sessions (12 CR sessions in total). Cognitive Remediation will be integrated into the IPSRT sessions. Patients will be asked to undertake three CR practice sessions per week between therapy sessions (length depending on clinical state) for the three months of the CR intervention. Therapists will provide on-line feedback once between face-to-face sessions. After 12 sessions, the package will continue to be available to patients for the rest of the intervention (i.e. until 12 months post baseline) should they wish to continue to practice. Therapist tasks completed during the therapy session will include:
a) reviewing performance and progress
b) discussing strategy on individual tasks and formulating a range of problem solving strategies
c) relating strategy to real-life situations (according to the manual of Bowie, Gupta and Holshausen)
d) selecting new tasks from the battery available.
Detailed information on patient adherence to prescribed CR practice sessions is available from the CR website, which gives information on practice sessions (dates, duration, tasks practiced, accuracy and speed).

Outcomes
Primary outcome [1] 298814 0
Change in a composite cognitive score between baseline and 12 months The composite score will be calculated by computing z scores for each variable (change Baseline-Follow-up/standard deviation of the change). Scores will be adjusted so that a positive score reflects better performance for each variable. The z score for each variable will be added and divided by the number of variables to create a composite z score for change. The composite score is comprised of the following variables Groton Maze Learning Task - total errors, Rey Auditory-Verbal Learning Task - total words recalled lists 1-5 Rey Auditory-Verbal Learning Task - words recalled delayed recall Letter Fluency - total words, Category Fluency - total words Category Fluency Switching - total words Digit Span - total forwards plus backwards Timed Chase Test - time.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation sequence is generated ahead of the trial and is held in a secure filing cabinet in sealed envelopes by the independent staff member.
After the participants signs the consent form and complete the baseline assessment, the research assistant contacts the holder of the allocation who issues the next sealed envelope with the randomisation inside..


Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated in permuted blocks, stratified by bipolar/unipolar and site (Christchurch, Nelson, Wellington).
Masking / blinding

Efficacy
Statistical methods / analysis
General linear models will be used to compare efficacy outcome measures between randomised groups. These models will include treatment group and stratum as fixed factors and as appropriate will include baseline measures as co-variates.
We have powered the study based on the cognitive outcomes demonstrated in our preliminary study of metacognitive therapy. This involved a cognitive intervention which produced positive effect size differences compared with a therapy involving no cognitive intervention, of 0.5 to 0.7 on attention and executive functioning. For a similar effect size of 0.5 for neuropsychological outcomes, 64 patients per group would also be necessary for 80% power. We aim to recruit 160 participants to allow up to 20% attrition (treatment drop-out or those who do not agree to take part in the second neuropsychological testing) to ensure a final group size in each arm of 64. All statistical tests will utilise a 2-tailed p-value of <0.05 to indicate statistical significance.

Summary
Brief summary
Aim
To compare a 12-month intervention involving Interpersonal and Social Rhythms Therapy combined with Cognitive Remediation (IPSRT-CR), with IPSRT alone, on cognitive functioning, everyday functioning, and mood morbidity in patients with a recurrent mood disorder.

Primary Hypothesis
IPSRT-CR, compared with IPSRT alone, will result in significantly improved cognitive functioning over the 12-month treatment period.
Secondary Hypotheses
a) IPSRT-CR will be associated with improved cognitive functioning at 18-month follow-up compared with IPSRT alone
b) IPSRT-CR will be superior to IPSRT alone in improving general functioning over the course of treatment and during the 12-month follow-up period
c) Overall mood related morbidity will be less during the treatment and in the 12-month follow-up period in patients randomised to the IPSRT-CR intervention

Sample
One hundred and sixty adults with mood disorder (bipolar disorder I or II, or Bipolar NOS or major depressive disorder (MDD)) will be recruited on discharge from SMHS in Canterbury, Nelson/Marlborough and Wellington.
Interventions
The 12-month IPSRT-CR intervention will involve IPSRT and Cognitive Remediation, the latter delivered by computer and supervised by therapists. The control intervention will be IPSRT alone (i.e., without the Cognitive Remediation component). Time spent with the therapist will be the same for each group.

Interpersonal and Social Rhythm Therapy
IPSRT will be delivered according to a manualised protocol. IPSRT will involve weekly sessions for 10-12 weeks followed by 8 fortnightly, and then 4 monthly sessions (total 24 sessions). If there is deterioration in the patient’s mood, they may be seen more regularly. All sessions will be audio-taped and randomly selected and rated to ensure adherence to therapy protocols. All therapists will participate in regular and ongoing supervision.

Cognitive Remediation
Patients will be introduced by their therapists to a computerised cognitive remediation package (provided free of charge by Scientific Brain Training Professional (SBT-pro) - www.scientificbraintrainingpro.com). This will begin between weeks 7-9 and will continue at the 8 fortnightly sessions (12 CR sessions in total). Patients will be asked to undertake three practice sessions per week between therapy sessions. Therapists will provide on-line feedback once between face-to-face sessions. After 12 sessions, the package will continue to be available to patients should they wish to continue to practice. Tasks completed during the therapy session will include:
a) reviewing performance and progress
b) discussing strategy on individual tasks and formulating a range of problem solving strategies
c) relating strategy to real-life situations
d) selecting new tasks from the battery available
