Description of intervention(s) / exposure
A pilot Randomised Control Trial (RCT) of group Cognitive Behavioural Therapy (CBT)to assist  prisoners to manage mood and persistent symptoms following TBI.
A manualised programme will be delivered to cohorts of 12 sentenced male prisoners who have a criminal history of violence, burglary or sexual offences. The manualised programme has been adapted from a programme developed for anger management. The programme will be administered by a Registered Psychologist and Intern Psychologist within the health space inside the prison. The programme is manualised and will be delivered in 10 x 1 hour sessions, across 5 weeks. The study will involve 72 men in total. The sessions are summarised as below:
1 Introduction of facilitator and session structure

3 Psychoeducation on relationship between thoughts, emotions and behaviour using 5 part CBT model
4 Introduction of the concept of mindfulness.

Outcomes
Primary outcome [1] 302014 0
Scores on negative affect repair questionnaire.
Timepoint [1] 302014 0
The negative affect repair questionnaire will be administered at the commencement of the intervention, at completion of the 5 weeks of the intervention and again 12 post-completion of the intervention.
Primary outcome [2] 302015 0
TBI symptoms assessed using the Rivermead post concussion screen.
Timepoint [2] 302015 0
The Rivermead post concussion screen will be administered at the commencement of the intervention, at completion of the intervention and then 12 weeks after the intervention has been completed.
Secondary outcome [1] 334519 0
Number of violent episodes assessed by review of offender file notes and prison misconducts.
Timepoint [1] 334519 0
The file notes will be measured at the commencement of the intervention, immediately following completion of the intervention and 12 weeks after the intervention has been completed.

Eligibility
Key inclusion criteria
Any man who has reported at least one TBI in their lifetime (based on the screening offered to all prisoners on arrival to the prison) who has been imprisoned for a violent, burglary or sexual offence (groups found to experience particularly high rates of TBI in screening data) will be included.
Minimum age
18 Years
Maximum age
No limit
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
Men who are unable to speak English and those with active psychosis are excluded as these would both prevent engagement in the intervention and completion of the pre and post intervention measures.
Men who following assessment from a psychologist have barriers to participating in a group format or non-associations with other group members will also be excluded.

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)
Once all consenting participants were assessed for suitability for inclusion they were assigned a sealed opaque envelope which allocated them to the intervention or wait list control. The administrator of the intervention was not involved in this process
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using paper based allocation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Statistical methods / analysis
The sample size was calculated using G power 3.1.0 to identify the number of group participants required to provide for meaningful analysis. The required sample size was calculated as 62 with a medium effect size of 0.3 (a=0.05, power = 80%, Number of groups = 2, number of measurements = 3). The effect size was estimated from other studies which report an appropriate effect size for a positive psychological intervention as being between 0.23-0.34. It is acknowledged that prison populations are relatively mobile, both from criminal rehabilitation (certain programmes happen in other parts of NZ) and release (both scheduled end dates and paroled releases, which is an unavoidable part of prison life). The sample was consequently increased to 72 to allow for this potential source of attrition.
A combination of repeated measures ANOVA and multi-level modelling will be used to determine the effectiveness of the intervention whilst controlling for demographic factors.

Summary
Brief summary
International literature has indicated that the lifetime prevalence of TBI in prison populations is higher than in the general population. Given that TBI can lead to difficulties with impulse control, irritability and decision making, there is likely to be a link between TBI history and subsequent behaviour. This pilot RCT study aims to trial a targeted psychological intervention utilising cognitive behavioural therapy with consenting prisoners who are experiencing persistent symptoms from TBI, to determine if the intervention is effective in symptom management, preventing re-injury and subsequent offending behaviour.
