Evaluation of Lifetime Stressors (ELS)

 

Evaluation of Lifetime Stressors (ELS)

Krinsley, 1996

Description

The Evaluation of Lifetime Stressors (ELS) is a research protocol for adolescents or adults comprised of a self-report questionnaire and semi-structured interview that examines a range of traumatic experiences across the lifespan. The 56-item questionnaire assesses experiences with disasters, illnesses, accidents, violence, combat, and other traumas by offering four response options ("yes, I can remember this," "I'm not sure if this happened," "No, but this happened to someone else in my family", and "No, this did not happen"). The 56-item interview is organized into nine modules (some of which are optional) that examine the non-negative responses on the questionnaire by providing specific probe questions for each item.

The interview provides a way to explore dimensions of each trauma including trauma type, perpetrators/victims, duration, frequency, perceptions of threats and emotional response, and others. A summary of the information can be captured in the Traumatic Events Summary prepared by the interviewer. Finally, an in-depth querying interview is provided to assess the worst two or three events to examine dimensions such as dissociation, disclosure, and treatment. This measure aims for high sensitivity by allowing uncertain responses and inclusion of indirect questions that have low emotional potential.

Sample Item

Have you ever been in a war zone or other very dangerous area? ("Yes, this happened to me," "I'm not sure if this happened," "No, but this happened to someone I knew," "No, this did not happen").
