NCT05257837

Brief Summary

The investigators' previous research has shown that children exposed to media characters with guns in movies and video games are more likely to use real guns themselves (e.g., touch them, hold them, pull the trigger). This research tests whether exposure to a gun safety video a week before the study can help counteract dangerous behavior around guns.

Outcome Measures

Primary Outcomes (7)

  • Behavioral: Gun Location

    Trained research assistants, blind to video game condition and experimental hypotheses, will independently code the play session videos. Coders will identify whether the participants found the handguns, how long the participants held the handgun, and whether or not they pulled the trigger.

    20 minutes play session

  • Behavioral: Gun Location Response - Told Adult

    If the participants found the handguns, the coders will identify whether the participants told an adult.

    20 minutes play session

  • Behavioral: Gun Location Response - Touched Gun

    If the participants found the handguns, the coders will identify whether the participants touched the handgun.

    20 minute play session

  • Behavioral: Gun Holding Time

    If participants handle the gun, coders will record how long the gun was held.

    20 minutes play session

  • Behavioral: Trigger Pulled

    When the gun was handled, this measures whether or not the participant(s) pulled the trigger.

    20 minute play session

  • Number of Trigger Pulls

    The two guns hidden in the playroom contain sensors that count how often the trigger is pulled with sufficient force to discharge the gun. A counter on the weapon displays the number of pulls, which will be entered into a data file along with the observational data described below. Observational data will also be used to confirm trigger pull counts. Note: This measure includes all 216 participants who found the handguns.

    20 minutes play session

  • Gun Pointing With Trigger Pull

    Trained research assistants, blind to video game condition and experimental hypotheses, will independently code the play session videos. If participants pulled the trigger, were they pointing the gun at themselves or their partners? Calculations done using all participants who found a firearm.

    20 minute play session

Secondary Outcomes (1)

  • Attitudes Toward Guns

Gun safety vid x Movie clip - guns present

EXPERIMENTAL

Participants in this condition will view a gun safety video featuring The Ohio State University Chief of Police about a week before coming into the lab. In the lab, they will watch a \~20 minute clip of either The Rocketeer or National Treasure featuring guns.

Behavioral: Gun handling behaviorOther: Debriefing

ACTIVE COMPARATOR

Participants in this condition will view a gun safety video featuring The Ohio State University Chief of Police about a week before coming into the lab. In the lab, they will watch a \~20 minute clip of either The Rocketeer or National Treasure with the guns edited out.

Behavioral: Gun handling behaviorOther: Debriefing

Seatbelt safety video x Movie clip - guns present

ACTIVE COMPARATOR

Participants in this condition will view a seatbelt safety video about a week before coming into the lab. In the lab, they will watch a \~20 minute clip of either The Rocketeer or National Treasure featuring guns.

Behavioral: Gun handling behaviorOther: Debriefing

ACTIVE COMPARATOR

Participants in this condition will view a seatbelt safety video about a week before coming into the lab. In the lab, they will watch a \~20 minute clip of either The Rocketeer or National Treasure featuring guns.

Behavioral: Gun handling behaviorOther: Debriefing

Interventions

Children will play in an observed room for 20 minutes. Aside from a selection of toys, two real handguns will be placed in a drawer. The handguns have been modified so they cannot fire. Inside the magazine, the handgun contains no bullets. Instead, it contains a sensor that counts the number of times the trigger is pulled with sufficient force to discharge the gun. This allows us to distinguish reliably the children who pull the trigger from those who handle the gun but do not pull the trigger

Children and their parents will be debriefed on the actual purpose of the study, including the role of the safety video and how the movie clips were edited.

Masking Details
Participants did not know which condition they were in. Participants' parents were aware of the deception (hidden gun) and what condition their children were in (gun safety or seatbelt safety; movie with or without guns). Research personnel knew conditions as well. Research assistants who transcribed recorded laboratory sessions did not know what condition they were coding (eg. what type of movie participants watched) Research assistants coding the recorded observational data will be blind to the conditions of the participants they are coding, as well as the experimental hypotheses of the study.

Intervention Model
PARALLEL
Model Details: Participants are randomly assigned to watch a safety video about guns or a safety video about seatbelts. Participants are then randomly assigned to watch a movie containing guns, or a movie not containing guns. Outlier data will be excluded in analysis.
