This issue includes the structure, instructions for use, and reliability and validity indices of a questionnaire that evaluates: (a) anger as a characteristic, and (b) ways of expressing anger (externalization, suppression, control).

As accompanying the questionnaire, for the evaluation of anger, we designed and weighted two more questionnaires. One of them reflects negative expectations and the degree of despair of children for the future, and the other reflects the disappointment of expectations and the hindrance-frustration of children's goals.

This issue is complemented by two more issues, in which the structure, instructions for use, and reliability and validity indices of questionnaires for the evaluation of aggression, bullying, and exposure to incidents of aggression and violence are presented.
