General Information

The EXPAGG Modified for Children version is a form of the questionnaire devised by Campbell, Muncer, and Coyle (1992) but modified for children. The questionnaire contains items relating to the causes, social value, form, aims, social facilitators, emotions, cognitions, and reputational aspects connected with acts of aggression by the respondent. Each item is an incomplete statement about aggression, followed by two alternatives, one instrumental and the other expressive. The respondent is asked to mark the one which he or she agrees with most.
