Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pilot study and randomised controlled trial: Frequency of aggressive acts will be measured using a self-report 5-item version of the Overt Aggression Scale Modified at baseline and at every 3 months during treatment (i.e., months 3, 6, 9, and 12) and every 3 months post-treatment for one year (i.e., months 15, 18, 21, and 24). | — |
Secondary
| Measure | Time frame |
|---|---|
| Pilot study: Unless otherwise stated, the secondary outcome measures are collected at baseline and every 6 months during treatment (i.e., months 6 and 12) and every 6 months post-treatment for one year (i.e., months 18 and 24). 1. Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM). A self-report questionnaire designed to be administered before and after therapy. The client is asked to respond to 34 questions about how they have been feeling over the last week, using a 5-point scale ranging from 'not at all' to 'most or all of the time'. The 34 items of the measure cover four dimensions: Subjective well-being, Problems/symptoms, Life functioning, and Risk/harm. 2. Psychopathic Personality Inventory- Revised (PPI-R 154; Lilienfeld, 2005). The PPI-R is a 154-item self-report measure of both global psychopathy and the component traits of psychopathy. Like the original PPI, the PPI-R is construct valid, time efficient, and can detect response styles potentially relevant to psychopathy (i.e. positive or negative impression management, random or careless responding). Rather than focusing exclusively on antisocial or criminal behaviors, the PPI-R measures the continuum of psychopathic personality traits present in a range of individuals and can be used in both clinical (e.g. forensic) and non-clinical (e.g. student, community) settings. 3. MacArthur Community Violence Screening Instrument (MCVSI; Steadman et al., 1998; 2000): 18-item semi-structured interview to measure the frequency with which individuals have been subject to and/or have engaged in particular violent behaviours. 4. Offending behaviour structured interview for offending behaviour designed to record offending activity. Consists of 17 “yes” or “no” self-report response-type questions. Each question is related to a different type of offence (e.g., theft of motor vehicles, shoplifting, possession of an offensive weapon/firearms, and drug offences).
