Firearm Secure Storage Device Distribution RCT
A study testing Cable locks, Lock box and Lock box and cable locks in people with Firearm Safety and Firearm Safety Storage, run by University of Pennsylvania.
Trial summary
This study aims to learn how to best promote safe firearm storage in the community. Firearm injuries are a major public health concern, and securely storing firearms can help prevent accidental injuries, suicide, and unauthorized access. Read more about this study

About this study
Official title: Comparative Effectiveness of Firearm Secure Storage Device Distribution Strategies: A Hybrid Type 1 Effectiveness-Implementation Randomized Clinical Trial
This study aims to learn how to best promote safe firearm storage in the community. Firearm injuries are a major public health concern, and securely storing firearms can help prevent accidental injuries, suicide, and unauthorized access. This research will test whether providing people with a choice of firearm storage devices improves safe storage practices compared to providing standard cable locks alone. Adults who are patients, visitors, or employees at participating Penn Medicine community health centers may choose to enroll by scanning a QR code displayed at the site. After reviewing study information and providing consent, participants will complete a short online survey about firearm ownership and storage practices. Participants will then be randomly assigned to receive either cable locks or a choice of storage devices such as a lock box and/or cable locks, which will be mailed to their home at no cost. Participants will receive firearm safety educational materials and will be asked to complete brief follow-up surveys by text message about one month and three months later. Some participants and health center staff may also be invited to participate in interviews about their experiences with the program. The goal of this research is to identify practical and acceptable ways for health systems to support safe firearm storage and reduce firearm-related injuries in diverse communities.

Lock boxDevice
Participants assigned to this intervention will receive one firearm lock box at no cost. The lock box will be mailed to the participant's home along with firearm safety educational materials.
Lock box and cable locksDevice
Participants assigned to this intervention will receive one firearm lock box and up to four firearm cable locks at no cost. The storage devices will be mailed to the participant's home along with firearm safety educational materials.
| Study group | Role | What they receive |
|---|---|---|
| Up to 5 cable locks | Active comparator | Choice of preferred device Receives: Device: Cable locks |
| Lock box only | Active comparator | Choice of preferred device Receives: Device: Lock box |
| Lock box and cable locks | Active comparator | Choice of preferred device Receives: Device: Lock box and cable locks |
What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Participants Reporting All Firearms Stored Securely at 30 Days
Proportion of participants reporting that all firearms in or around their home are stored securely at the 30-day follow-up assessment. Secure storage will be assessed through participant self-report using the following response options: Yes, all of them (1); Yes, some of them (2); None of them (3); Not sure (4); No guns in or around home (5); and Prefer not to answer (6).
Measured: 30 days after enrollment
Secondary outcomes (5)
Number of firearm storage devices requested
Among patients randomized to the preferred device arm, the number of firearm storage devices requested by participants will be assessed.
Measured: Baseline (enrollment)
Proportion of participants with all firearms stored securely at 3 months
Proportion of participants reporting that all firearms in the household are stored securely at the 3-month follow-up assessment
Measured: 3 months after enrollment
Proportion of participants changing from no firearms stored securely to some or all firearms stored securely at 1 month
Among participants reporting at enrollment that no firearms were stored securely, the proportion who report that some or all firearms are stored securely at the 1-month follow-up assessment
Measured: Baseline and 1 month
Proportion of participants changing from no firearms stored securely to some or all firearms stored securely at 3 months
Among participants reporting at enrollment that no firearms were stored securely, the proportion who report that some or all firearms are stored securely at the 3-month follow-up assessment
Measured: Baseline and 3 months
Incremental intervention cost per participant
Incremental cost of delivering the intervention, including the cost of firearm storage devices and associated shipping costs. Costs will be calculated in US dollar per participant
Measured: Up to 3 months after enrollment
