independent studies, confirming the importance of assessing suicidal affect, behaviors, and cognition as a single suicidal construct. The SABCS was the first suicide risk measure to be developed through both classical test theory (CTT) and item response theory (IRT) psychometric approaches and to show significant improvements over a highly endorsed comparison measure. The SABCS was shown to have higher internal reliability, and to be a better predictor of both future suicidal behaviors and total suicidality over an existing standard. Suicide Behaviors Questionnaire The Suicide Behaviors Questionnaire (SBQ) is a self-report measure developed by Linehan in 1981. In 1988 it was transformed from a long questionnaire to a short four questions that can be completed in about 5 minutes. Answers are on a Likert scale that ranges in size for each question, based on data from the original questionnaire. It is designed for adults and results tend to correlate with other measures, such as the SSI. It is popular because it is easy to use as a screening tool, but at only four questions, fails to provide detailed information. Life Orientation Inventory The Life Orientation Inventory (LOI) is a self-report measure that comes in both a 30 question and 110 question form. Both forms use a 4-point Likert scale to answer items, which are divided into six sub-scales on the longer form: self-esteem vulnerability, over-investment, overdetermined misery, affective domination, alienation, and suicide tenability. This scale has strong reliability and validity, and has been shown to be able to differentiate between control, depressed, possibly suicidal, and highly suicidal individuals. It also contains 3 validity indices, similar to the MMPI. However, while useful, this inventory is now out of print. Reasons For Living Inventory The Reasons For Living Inventory (RFL) is theoretically based, and measures the probability of suicide based on the theory that some factors may mitigate suicidal thoughts. It was developed in 1983 by Linehan et al. and contains 48 items answered on a Likert scale from 1 to 6. The measure is divided into six subscales: survival and coping beliefs, responsibility to family, child concerns, fear of suicide, fear of social disproval, and moral objections. Scores are reported as an average for the total and each sub-scale. The scale is shown to be fairly reliable and valid, but is still mostly seen in research as compared to clinical use. Other variations of the scale include the College Students Reasons for
