Hostile Bias Modification Training Online Study II

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to see how people respond on a word completion task relates to how they behave and respond to situations in the real world. This is a two part research study. At time-point one, participants will fill out some brief personality surveys. They will also read several short scenarios and imagine how they would react and/or interpret these situations in real life. They will also complete a vocabulary task where they will sort word fragments based on type as quickly as they are able. Participants will be asked to return in 24-96 hours for part two where they will repeat a similar scenario reading activity as during time one and fill out a brief questionnaire about your recent behaviors.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: This is an online study. Volunteer assignment to each of the two experimental conditions is semi-randomized (i.e. random except that computer ensure equal sample sizes across experimental conditions). The randomized assigning of participants is done by the study web-page/program at volunteerscience.com. The computer program randomly assigned volunteers to one of the two conditions when they begin the study.
Masking: Single

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hostile Attribution Bias | Adapted from the Angry Cognitions Scale (Martin and Dahlen 2007). Volunteers read hypothetical scenarios where another person acted aggressively but with unclear intent (e.g., You are driving through a residential area when someone backs their car out of a driveway and nearly hits you.). Volunteers respond to items (from Very Unlikely to Very Likely) to indicate how they would think about the situation (e.g., He/she did that just so I'd have to stop. He/she was trying to scare me.). Volunteers responded to one set (4 scenarios) at time point one and a second set (5 scenarios) at time point two. Reponses were summed within each scenario and averaged across scenarios to indicate level of hostile attribution bias. Individual scores at each time point could range from 0 (no hostile attribution bias) to 24 (high hostile attribution bias). | 24-96 hours post HBMT | 
| Driving Aggression | State Aggression Survey: This survey is adapted from several others in the literature to measure variance along the normal spectrum of aggressive behaviors in daily life that the average person might display (Álvarez-García, et al., 2016; Deffenbacher, et al., 2001; Deffenbacher, J. et al., 2002). The survey specifically asks about driving behaviors (e.g., yelling at other drivers). Scoring is count of aggressive behaviors during reporting period. | 24-96 hours post HBMT | 
| Aggression On Social Media | Seven items adapted from the Cyber-Aggression Questionnaire for Adolescents by Álvarez-García et al. (2016). Volunteers reported at time point two how often (during preceding 24 h) they engaged in various aggressive online behaviors (e.g., posted rude comments about someone on a social network). Response choices ranged from 1 = never to 4 = always. Scores were recorded dichotomously to represent whether a volunteer reported any online aggression during the reporting period (i.e. never was recoded as 0 to indicate no aggression, and all other responses were recoded as 1 to indicate at least some aggression. A higher percentage of volunteers in a study condition reporting usage of aggression on social media indicates a worse outcome for that study condition. | 24-96 hours post treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Anger | Trait Anger Scale: Brief measure of trait anger validated by Wilk et al., (2015). Scale (1-5, strongly disagree to strongly agree); Two questions regarding individual's perspective on their anger. Higher values indicate greater anger. | 24-96 hours post HBMT |
