Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Beyond Violence (BV) is an evidence-based intensive program developed specifically for female violent offenders to target co-morbid substance use disorder, post-traumatic stress disorder and women’s experiences and perpetration of violence. The BV treatment employs trauma theory as a basis for the intervention.
A manualised intervention, BV is a tertiary prevention program which utilises a multi-level approach through a variety of evidence-based therapeutic strategies (i.e. psycho-education, role playing, mindfulness activities, cognitive-behavioural restructuring, and grounding skills for trauma triggers) to address issues of mental health, substance abuse, trauma histories, and anger regulation.
BV is an intensive program run over 20 x 2 hour sessions, delivered face-to-face in prison in groups of 8-10 (INTERVENTION GROUP). The intervention is provided by two co-facilitators (one Aboriginal and one non-Aboriginal woman). Facilitators will record session attendance and make brief clinical notes. To measure satisfaction with treatment, at the end of each session, participants complete a survey to assess the helpfulness of session components and satisfaction levels.
Recruitment to the intervention will occur through identification of potentially eligible participants from administrative databases of offenders, and self-referral (word-of-mouth, posters displayed in prison clinics). Allocation to the treatment group will occur on a first come basis.
The CONTROL GROUP will comprise women who meet the inclusion criteria who may participate in other programs offered in the prison setting (i.e. ‘Treatment as usual’ (TAU)) but do not receive the intervention. To avoid contamination we will initially recruit controls over one year then, over the following year, recruit for and administer the intervention at the same sites.

Outcomes
Primary outcome [1] 308446 0
Re-offending within 15 months post-release defined as a conviction (which could include re-incarceration) for any offence. The primary endpoint (re-offending) will be determined objectively from court record outcomes of convictions obtained from administrative data collections.

Re-offending will be assessed 15 months post-release from prison.

Other design features
The proposed study is a before-and-after trial, conducted over five years designed to measure the effectiveness of the multi-component violence prevention intervention among female offenders with a current and/or historical violent offences.

Contamination: Passage of intervention material to contemporaneous control prisoners within the same prison as the intervention group could, by providing a diluted form of the intervention to ‘controls’, bias the study and lead to a systematic underestimation of the true effect size. To avoid contamination as described by Zlotnick (2009), we will initially recruit controls over one year then, over the following year, recruit for and administer the intervention at the same sites.

Efficacy
Statistical methods / analysis
Primary outcome: The incidence rates of reoffending, the primary endpoint of interest, will be calculated and compared between two arms. For each member of the cohort, person-years at risk will be measured from the start date of release until the date of first offence. Kaplan-Meier methods will be used to assess the cumulative probability of offending after release. We will use Cox proportional hazard models to assess factors associated with offending. We will use an ‘intent-to-continue-treatment’ approach. A similar approach will be adopted for offences resulting in re-incarceration, a secondary outcome.

Secondary outcome: Repeated measure linear mixed models, with unstructured covariance matrix for random effects will be used to assess mental health and substance use responses to intervention during different time periods. By considering individual random slopes and intercepts, this model allows one to examine the influence of covariates over time. We also use an unstructured covariance matrix for random effects, allowing a correlation between the individual baseline level and the slopes for the mental health measures.
