Another limitation of anger management is that its success depends on the offender.
Howells found that participation in the therapy had little impact when compared to a control group who received no treatment.
However, this was not true for all offenders as some made significant progress when they'd had intense levels of anger prior.
Also offender who were open to change and were highly motivated experienced similar progress.
Therefore anger management may only benefit offenders who fit a certain profile and therefore it's limited in its effectiveness.
