Group and individual cognitive behavioural interventions for anger

There is growing evidence for the efficacy of anger treatment programmes, which aim to reduce inappropriate aggression in people with learning disabilities. To date they have been provided in both group and individual formats, but the differential efficacy of these approaches is yet to be assessed. Individuals with a learning disability and inappropriately expressed anger were assigned to either group or individual treatment or a waiting list control, depending on the availability of treatment options. In this way, 23 participants completed group treatment, 18 individual treatment and 21 were included in a waiting list control. Participants were assessed both before and after treatment using an anger provocation inventory. Improvements were found in the scores obtained on the anger inventory for both the group and individual treatments compared to the control using a 2 by 3 split plot ANOVA. There was no difference between group and individual treatments. These results replicate previous findings that suggest that both group and individual cognitive behavioural interventions are effective treatment options for people with learning disabilities, but do not support either method of delivery as the preferred option. Limitations of the data are discussed.
