“…In individuals with depression, those with a suicide attempt history had higher hypervigilance scores than those who did not have a suicide history (Ahmadpanah et al, ). In our study using the proposed SCS criteria, hypervigilance contributed to the predictive validity of the diagnosis (Yaseen et al, ).…”

“…Depressive turmoil is a form of emotion dysregulation, characterized by intense and deep negative feelings developed over a short period of time (Galynker, ). In our study assessing the proposed SCS criteria, depressive turmoil contributed to the predictive validity in relation to suicidal ideation and attempts (Yaseen et al, ). Depressive turmoil has been previously found to differentiate between those who died by suicide and those who did not within a four‐year prospective study (Fawcett et al, ).…”

“…Previous studies using the Suicide Crisis Inventory (SCI; previously termed the Suicide Trigger Scale (STS)), a self‐report measure of most of the SCS components, have found strong associations with suicidal behavior. A recent study by our group is the first to assess the proposed DSM criteria and its relation to suicidal behaviors among an inpatient population (Yaseen et al, ). Results of the study revealed that those who met criteria for the SCS, as compared with those who did not meet criteria, had significantly more severe suicidal ideation in the previous week.…”

“…When entered together in a model, only anhedonia and entrapment had independent predictive validity for suicidal ideation over the six months following the assessment. Finally, social withdrawal was found to be an independent predictor of suicidal thoughts and behaviors in the four weeks following the index assessment (Galynker et al, ; Yaseen, Hawes, Barzilay, & Galynker, ).…”

Suicide is a major public health problem, and suicide rates are still on the rise. Current strategies for identifying individuals at risk for suicide, such as the use of a patient's self‐reported suicidal ideation or evidence of past suicide attempts, have not been sufficient in reducing suicide rates. Recently, research groups have been focused on determining the acute mental state preceding a suicide attempt. The development of an acute suicidal diagnosis, the Suicide Crisis Syndrome (SCS), is aimed at capturing this state to better treat individuals. The SCS has five main evidence‐based components—entrapment, affective disturbance, loss of cognitive control, hyperarousal, and social withdrawal. The SCS may provide clinicians with the ability to identify individuals who are experiencing an acute pre‐suicidal mental state, regardless of their self‐reported suicidal ideation. Future research leading to the incorporation of this diagnosis into clinical practice could improve the quality of care and reduce the personal, societal, and legal burden of suicide.

Objective: This study explores the prediction of near-term suicidal behavior using machine learning (ML) analyses of the Suicide Crisis Inventory (SCI), which measures the Suicide Crisis Syndrome, a presuicidal mental state. Methods: SCI data were collected from high-risk psychiatric inpatients (N = 591) grouped based on their short-term suicidal behavior, that is, those who attempted suicide between intake and 1-month follow-up dates (N = 20) and those who did not (N = 571). Data were analyzed using three predictive algorithms (logistic regression, random forest, and gradient boosting) and three sampling approaches (split sample, Synthetic minority oversampling technique, and enhanced bootstrap). Results: The enhanced bootstrap approach considerably outperformed the other sampling approaches, with random forest (98.0% precision; 33.9% recall; 71.0% Area under the precision-recall curve [AUPRC]; and 87.8% Area under the receiver operating characteristic [AUROC]) and gradient boosting (94.0% precision; 48.9% recall; 70.5% AUPRC; and 89.4% AUROC) algorithms performing best in predicting positive cases of near-term suicidal behavior using this dataset. Conclusions: ML can be useful in analyzing data from psychometric scales, such as the SCI, and for predicting near-term suicidal behavior. However, in cases such as the current analysis where the data are highly imbalanced, the optimal method of measuring performance must be carefully considered and selected.
