Dimensions of Anger Reactions-Revised: Validation of a brief anger measure in Australia and Spain.

OBJECTIVE: A validated, brief measure of anger is needed in clinical settings to screen for problematic anger. This study examined the validity of the seven-item Dimensions of Anger Reactions-Revised (DAR-R), including a version for the Spanish population.

METHOD: Multiple psychometric instruments administered to 541 (76.6% female) adults in Australia and 1,115 (56.3% female) in Spain were analyzed.

RESULTS: A two-factor model (anger response and anger impairment) was confirmed. Concurrent, convergent, and discriminant validity were supported. Anger response items strongly correlated with established measures of anger/aggression State-Trait Anger Expression Inventory (Aggression Questionnaire), whereas anger impairment items strongly correlated with anxiety Generalized Anxiety Disorder-7 and depression Patient Health Questionnaire-9 measures. Internal consistency and test-retest reliability (3 months) were good. Cut-off scores for problematic anger were established. There were no gender differences in anger in the Spanish sample, but Australian males had higher anger scores than females.

CONCLUSION: Results substantiate the utility of the DAR-R as a concise, clinically informative measure of anger.
