Primary Outcomes

Change in Anger State from baseline to end of the experiment

The STAXI-2 includes a measure of anger state (15 items) with responses ranging from 1="Absolutely not" to 3="A lot"

Time frame: The STAXI-2 will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study)

Trait Injustice

The Trait Injustice Experiences Questionnaire is a measure of perceived trait injustice beliefs that has 12 items, with responses ranging from 0="never" to 4="always". This measure will be used as moderator of the effects of the experiment on anger

Time frame: This measure will be administered at Baseline

Frustration Discomfort Scale

This is a measure of frustration intolerance. The scale has 28 items that are gouped in 4 subscales. Items have a 1-to-5 response scale ranging from "nothing" to "a lot". In addition to trait injustice, this measure will also be used in secondary analyses as a moderator of the effects of the experiment on anger

Time frame: This measure will be administered at Baseline

Change in State Injustice from baseline to end of the experiment

The State Injustice Experiences Questionnaire is a measure of perceived state injustice beliefs that has 12 items, with responses ranging from 0="never" to 4="always". This measure will be used as an experimental check (whether exclusion in the experiment effectively increased the sense of injustice in the short term)
