Abstract

INTRODUCTION: Clinician- or self-administered scales are frequently used to assist in detecting risk of death by suicide and to determine the effectiveness of interventions. No recent review studies have examined whether these scales are sensitive to change. We conducted a scoping review to identify suicide risk scales that are sensitive to change. MATERIAL AND METHODS: We searched Medline and Excerpta Medica Database from inception through March 17, 2022, to identify randomized trials, pooled analysis, quasi-experimental studies, and cohort studies reporting on sensitivity to change of suicide risk scales. We assessed sensitivity to change by examining internal and external responsiveness. Internal responsiveness evaluates whether the scale measures changes in suicide-related symptoms in response to an intervention while external responsiveness assess whether changes in the scale correspond to changes in risk of suicide. We summarized findings across studies using descriptive analysis.

RESULTS: Among 38 eligible scales, we identified 27 scales that included items that were modifiable to change. However, only 7 scales had been studied to determine their sensitivity to change based on internal or external responsiveness. While the results of studies suggested that 6 scales have internal responsiveness, none of the included studies confirmed that scales have external responsiveness.

DISCUSSION: A few suicide risk scales are internally responsive and may be useful in a clinical or research setting. It is unclear, however, whether changes in scores correspond to an actual change in suicide risk. Future research should confirm the external responsiveness of scales using robust metrics including suicide mortality.
