Trait Injustice, Social Exclusion, and Anger

June 17, 2020 updated by: Universitat Jaume I

Trait Injustice and Its Effects on Anger Induced by Social Exclusion

Participants will be randomly allocated to one of two experimental conditions: social exclusion or social inclusion. Participants, but not experimenters will be blind to the assignment. Pre- and post-tests will be administered. Participants will be offered 7 euros in compensation for participating.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
131

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 30 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Social exclusion
Cyberball is a ball-passing task in which the participant plays with two virtual players. In this condition, the user receives fewer passes than the other two participants (i.e., 10 out of 60).
Other: Cyberball experimental task
Cyberball is an experimental task in which participants have to pass a ball to two virtual players during 60 passes in total
Active Comparator: Social inclusion
Cyberball is a ball-passing task in which the participant plays with two virtual players. In this condition, the user receives a comparable number of passes than the other two participants (i.e., 20 out of 60).
Other: Cyberball experimental task
Cyberball is an experimental task in which participants have to pass a ball to two virtual players during 60 passes in total

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Anger State from baseline to end of the experiment
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)
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)
Trait Injustice
Time Frame: This measure will be administered at Baseline
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frustration Discomfort Scale
Time Frame: This measure will be administered at Baseline
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
Change in State Injustice from baseline to end of the experiment
Time Frame: This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study)
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)
Change in State Anxiety from baseline to end of the experiment
Time Frame: This measure will be administered twice: at Baseline and at the same day of Baseline assessment just after the experimental task (end of study)
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)
Cyberball Experiences post-experimental check Questionnaire
Time Frame: This measure will be administered at the same day of Baseline assessment just after the experimental task (end of study)
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)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
