Validity and reactivity of a system of self-monitoring suicide ideation

The present study describes the rationale and validation of a self-monitoring approach for suicide ideation. A sample of 49 severely ideating 18- to 24-year-old college students volunteering for a treatment study for chronic ideators served as subjects. A three-item self-monitoring scale designed to assess the strength, duration, and level of control relative to suicide ideation was designed and utilized. Positive correlations with previously validated measures of suicide ideation support the validity of the use of self-monitoring. In addition, positive relationships with measures of depression and hopelessness provide evidence of concurrent validity. There was no evidence that self-monitoring and concomitant increased attention to ideation increased suicidality. In fact, decreases were noted in measures of suicide ideation following a 2-week period of self-monitoring. Together these findings support the addition of self-monitoring to the list of dependent measures for addressing suicidal behavior.
