However, a study by Rice (1997) found that psychopaths given anger management or social skills training showed increased rates of reoffending, possibly because the skills and confidence they gained from the programme made them more effective at manipulating others. This suggests that anger management may not be effective, as it could increase criminal behaviour instead of modifying it. As such, anger management will need to be used with caution to avoid reoffending.
One methodological issue with anger management is that practising the skills in role-play situations is argued to be too different from real life. The level of intensity of emotion is greater in a real-life situation, so the offender could find the ability to apply the skills is hindered and they revert to their former behaviour. Therefore, the studies that show high levels of efficacy need to be considered with caution, as the efficacy of anger management programmes is difficult to track in real life settings.
Ultimately it is aggression (and crime) that we are trying to reduce
This suggests that anger management programmes may not be effective in modifying criminal behaviour because it assumes that the cause of criminality is anger, whereas there may be other important factors
There are also financial implications to be considered. For example, the cost to the economy of reoffending or recidivism is at least £9.5 billion per year. Any method that may reduce even a small amount of offending or reoffending must offer benefits to society. If offenders learn to control their anger better, once they are released from prison this may prevent them committing further crimes.
