This paper describes an evaluation of a group intervention for reducing ina
ppropriately expressed anger (as aggression) in people with intellectual di
sabilities. Group intervention was compared to a treatment as usual group c
onsisting of people referred to the group but who had to wait to participat
e. The intervention used was based on the work of Novaco (1976; 1978) and B
enson (1994). However, further modifications to the group that emphasized t
he contextual perspective of anger, such as the participants being accompan
ied by a support worker and more collaborative recording procedures, were d
evised. A reduction in expressed anger and measured levels of depression oc
curred after group treatment. Reductions in expressed anger were maintained
at 6 and 12 months follow up. However, scores on the depression scale tend
ed to increase on follow up. While caution must be expressed when consideri
ng these results, this type of intervention shows promise for reducing inap
propriately expressed anger in people with intellectual disabilities Sugges
tions are made for future research and clinical practice. (C) 2000 Elsevier
