Hello. Following my previous questions, I wonder if I could also ask a question about the State-Trait Anger Expression Inventory? Is there anything I should keep in mind when I use it?

My pleasure.

That’s so kind of you for the detailed reply.

The State-Trait Anger Expression Inventory is a widely used and well-validated measure of anger. And you could use its child/adolescent version. Youths rate (on 3-point scales) how often or how intensely they experience angry feelings (e.g., “I feel annoyed” 1 = not at all, 2 = somewhat, 3 = very much; “I try to calm down” 1 = hardly ever, 2 = sometimes, 3 = often). Items are averaged (some are reverse-coded) to create subscales for state anger, trait anger, and anger control. State anger reflects the intensity of angry feelings youths are currently experiencing and the extent to which they feel like expressing those feelings. Trait anger indexes how often youths feel angry in general, and the anger-control scale reflects the extent to which youths try to control expressing their anger. Higher scores on state and trait anger reflect greater tendencies toward anger, whereas scores on anger control reflect greater tendencies toward controlling anger.
