Abstract

BACKGROUND:

Inpatient suicide is one of the major issues related with hospital patient safety. Although there are many studies addressing suicide in the psychiatric unit, little is known about suicide in a medical setting. This study included the development and validation of a screening tool for the assessment of suicide risk, specialized for medical inpatients.

METHODS:

The preliminary questionnaire was based on review of previous suicide ideation scales, mood scales, and clinical experiences of psychiatrists and clinical psychologists in Korea. Initially, the questionnaire consisted of 12 questions. One hundred adult medical inpatients were asked to perform the questionnaire. Explorative factor analysis was used to examine construct validity. Concurrent validity was evaluated by comparison with the Korean versions of the Beck Scale for Suicide Ideation (BSI), the Beck Hopelessness Scale (BHS), and the Hospital Anxiety and Depression Scale (HADS).

RESULTS:

Five questions were removed from the preliminary questionnaire by explorative factor analysis and seven questions remained to comprise the Suicide Risk Scale for Medical inpatients (SRSM). Explorative factor analysis showed that the SRSM is composed of a single factor. SRSM was highly reliable in terms of internal consistency (Cronbach's alpha 0.91). Concurrent validity with the BSI, BHS, and HADS was statistically significant. The proposed cut-off score of the SRSM was five.

CONCLUSION:

In conclusion, the SRSM is a valid and reliable measure for screening suicide risks in medical inpatients.
