Protocol - Lethality of Suicide Attempts

Add to My Toolkit
Description:

The Beck Lethality Scales includes eight items that measure the medical lethality of previous suicide attempts (e.g., shooting, jumping, and drug overdose). Each scale is rated from 0 to 10, based on an examination of the patient’s physical condition on admission, review of the medical charts, and consultation with the attending physician.

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:

Protocol:

BECK LETHALITY SCALES

Instructions to interviewer: These scales establish the lethality of patients’ suicide attempt(s). Use all available information to establish the lethality of each previous suicide attempt.

Enter the date (MM/YY) of each suicide attempt, then code the lethality of each suicide attempt, starting with the MOST recent suicide attempt. If the patient used more than one method, code each method, beginning with the MOST lethal. (Example: on 12/1/95, a patient attempted suicide by consuming a liter of grain alcohol and a gunshot to the abdomen. This would be coded as date: 12/95; primary code 0306; secondary code 0104.)

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
Requirement CategoryRequired
Major equipment No
Specialized training No
Specialized requirements for biospecimen collection No
Average time of greater than 15 minutes in an unaffected individual No
Mode of Administration

Interviewer-administered questionnaire

Life Stage:

Participants:

Adolescents and adults, ages 12 and older

Selection Rationale

The Beck Lethality Scales are generally accepted by researchers and have demonstrated interrater reliability and convergent validity.
