Variability in suicidal ideation: a better predictor of suicide attempts than intensity or duration of ideation?

Abstract

Background Much of the suicidology literature focuses on establishing contextual risk factors for suicidal behavior. However, the study of the parameters of suicidal behavior (e.g., intensity, duration, and variability) has been somewhat neglected . Having previously established a relationship between variability in suicidal ideation and a previous history of suicide attempts [Witte, T.K, Fitzpatrick, K.K., Warren, K.L., Schatschneider, C., Schmidt, N.B., submitted for publication. Naturalistic Evaluation of Suicidal Ideation: Variability and Relation to Attempt Status], we felt it important to assess the liability conferred by a variable pattern of ideation compared to the intensity and duration of suicidal thoughts. We also examined if there was an interaction between gender and the parameters of intensity, duration, and variability.Method One hundred eight participants (54 non-attempters, 35 single attempters, and 19 multiple attempters) completed the Suicide Probability Scale every day for 4 weeks, allowing us to measure the parameters of interest. These variables were entered into a regression model as predictors of previous suicide attempts.Results Consistent with prediction, high variability of ideation was the only significant predictor of previous attempt status. In addition, an interaction between gender and variability in suicidal ideation suggested that variability appeared more critical in predicting previous attempts for males.Limitations The limited number of multiple attempters in our sample and the use of college students limit the current study.Conclusions Variability appears to be the most potent predictor of attempt status among the parameters of suicidal ideation examined in the current study. This relationship appears to be particularly important in males, suggesting that fluctuating levels of suicidal ideation may confer future risk for suicide.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
