Protocol - Access to Lethal Means

Add to My Toolkit
Description:

This protocol includes three questions from the Centers for Disease Control and Prevention (CDC) 2004 Behavioral Risk Factor Surveillance System State (BRFSS) Questionnaire. These questions capture whether firearms are present in the home and, if so, how they are stored (e.g., loaded and unlocked).

Protocol:

The next questions are about firearms. We are asking these in a health survey because of our interest in firearm-related injuries. Please include weapons such as pistols, shotguns, and rifles but not BB guns, starter pistols, or guns that cannot fire. Include those kept in a garage, outdoor storage area, or motor vehicle.

1. Are any firearms kept in or around your home?

[ ] 1 Yes

[ ] 2 No [Go to closing statement]

[ ] 7 Don’t know/Not sure [Go to closing statement]

[ ] 9 Refused [Go to closing statement]

2. Are any of these firearms now loaded?

[ ] 1 Yes

[ ] 2 No [Go to closing statement]

[ ] 7 Don’t know/Not sure [Go to closing statement]

[ ] 9 Refused [Go to closing statement]

3. Are any of these loaded firearms also unlocked? By unlocked, we mean you do not need a key or combination to get the gun or to fire it. We don’t count a safety as a lock.

That’s my last question. Everyone’s answers will be combined to give us information about the health practices of people in this state. Thank you very much for your time and cooperation.

Availability:

Publicly available

Personnel and Training Required

The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs

The PhenX Working Group acknowledges these questions can be administered in a computerized or noncomputerized format (i.e., paper-and-pencil instrument). Computer software is necessary to develop computer-assisted instruments. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Requirements

Interviewer-administered questionnaire

Life Stage:

Adult

Participants:

Adults, ages 18 and older.

Specific Instructions:

This protocol includes questions that can potentially identify respondents who are at risk of suicide. Investigators implementing this protocol should consider developing a risk management plan specific to their study to ensure the safety of participants. The following links provide additional information and guidelines for suicide-related research:

Selection Rationale

These three questions from the Centers for Disease Control and Prevention (CDC) 2004 Behavioral Risk Factor Surveillance System State (BRFSS) Questionnaire were selected as the best standardized methodology for determining access to firearms. These questions were administered in the BRFSS in 1995-98, 2001, 2002, and 2004.

Release Date:

Definition

A questionnaire to determine availability of firearms in the home.

Purpose

The presence of firearms in the home is a strong predictor of suicide risk. Half of all suicides involve use of guns, and suicide rates are higher in areas where gun ownership is common.
