Protocol - Non-suicidal Self Injury

Add to My Toolkit
Description

The Self-Injurious Thoughts and Behaviors Interview (SITBI) is a structured interview that includes five modules assessing the presence, frequency, and characteristics of five types of self-injurious thoughts and behaviors: suicidal ideation, suicidal plans, suicidal gestures, suicidal attempts (including aborted and interrupted), and nonsuicidal self-injury. Each module begins with a screening question about lifetime presence of a self-injurious thought or behavior followed by items that measure age of onset, recent thoughts and behaviors, severity of thoughts and behaviors, probability of future behavior, and self-reported precipitants and functions of the behavior.

In addition to the adult and adolescent sort form presented below, other versions of the SITBI are available: adult and adolescent long form, follow-up short form (prospective studies), and self-report.

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:

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

Adolescents and adults, ages 12 and older

Selection Rationale

The Self-Injurious Thoughts and Behaviors Interview (SITBI) is a brief, low-burden questionnaire that is widely used in epidemiology studies of adults and adolescents. The SITBI has demonstrated interrater reliability and test-retest reliability, convergent validity (ideation), and corresponds to definitions for suicidal ideation and suicidal behavior endorsed by the Centers for Disease Control and Prevention (Crosby et al., 2011) and the U.S. Food and Drug Administration (FDA -Guidance for Industry Suicidal Ideation and Behavior: Prospective Assessment of Occurrence in Clinical Trials Office of Communications, Division of Drug Information Center for Drug Evaluation and Research Food and Drug Administration, 2012).
