Methods The STS-2 was administered to 141 adult psychiatric patients with suicidal ideation. Multiple statistical methods were used to explore construct validity and structure. Results Cronbach s alpha demonstrated excellent internal consistency. Factor analyses yielded two-component solutions with good agreement. The first component described near-psychotic somatization and ruminative flooding while the second described frantic hopelessness. ROC analysis determined an optimal cut score for a history of suicide attempt with significance of p . Logistic regression analysis found items sensitive to history of suicide attempt described ruminative flooding doom hopelessness entrapment and dread. Conclusions The STS-2 appears to measure a distinct and novel clinical entity which we speculatively term the suicide trigger state. High scores on the STS-2 associate with reported history of past suicide attempt. Background Though many chronic factors placing an individual at increased risk for suicide are well established the acute factors that lead a person to make a suicide attempt SA are not known. Chronic risk factors include suicidal ideation SI history of suicide attempts severe psychopathology history of psychiatric hospitalization substance abuse and poor social supports 1 2 . Among these SI and history of previous SA are most prominent and most relied upon in general clinical practice 3-7 . At present however no instruments are well established for the
