Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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"	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)
Primary	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	This measure will be administered at Baseline
Secondary	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	This measure will be administered at Baseline
Secondary	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)	This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study)
Secondary	Change in State Anxiety from baseline to end of the experiment	The STAI-S is a measure of perceived state anxiety that has 20 items, with responses ranging from 0="not at all" to 3="a lot". This measure will be used as an experimental check (whether exclusion in the experiment effectively increased anxiety in the short term)	This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study)
Secondary	Cyberball Experiences post-experimental check Questionnaire	In addition to exploring the effects of the experimental task on anxiety and anger, the Cyberball includes a measure of impact of the task on perceived inclusion and related concepts (isolation, belonging, perceived number of passes received, etc.). This will also be used as an experimental check	This measure will be administered at the same day of Baseline assessment just after the experimental task (end of study)
