Limitations
anger, psychiatric, alcohol abuse, impulsivity, irritability
A limitation of this study is it is based on a sample of highly impulsive repeat-violent offenders. Additionally, reliance on self-report to ascertain the impact of some of the variables on attrition (e.g. relationship status, number of dependents, accommodation type, impulsivity, anger, irritability, and alcohol abuse) may be subject to recall or response bias. It is possible that individuals who have a history of committing violent offences may feel the need to manage their public identity and may have modified their responses. Notwithstanding these limitations, this study also possesses considerable strengths. We have identified age, social support, education, time spent incarcerated, and psychiatric history are associated with attrition.
