A brief rating scale to assess repetition risk of self-harm is important for high-risk identification and early interventions in suicide prevention. The study aimed to examine the validity of the Chinese SAD PERSONS Scale (CSPS) and to evaluate its feasibility in clinical settings.Methods: One hundred and forty-seven patients with self-harm were recruited from the Emergency Department and assessed at baseline and the sixth month. The controls, 284 people without self-harm from the Family Medicine Department in the same hospital were recruited and assessed concurrently. The psychometric properties of the CSPS were examined using baseline and follow-up measurements that assessed a variety of suicide risk factors. Clinical feasibility and applicability of the CSPS were further evaluated by a group of general nurses who used case vignette approach in CSPS risk assessment in clinical settings. An open-ended question inquiring their opinions of scale adaptation to hospital inpatient assessment for suicide risks were also analyzed using content analysis.Results: The CSPS was significantly correlated with other scales measuring depression, hopelessness and suicide ideation. A cut-off point of the scale was at 4/5 in predicting 6-month self-harm repetition with the sensitivity and specificity being 65.4% and 58.1%, respectively. Based on the areas under the Receiver Operating Characteristic curves, the predictive validity of the scale showed a better performance than the other scales. Fifty-four nurses, evaluating the scale using case vignette found it a useful tool to raise the awareness of suicide risk and a considerable tool to be adopted into nursing care.Conclusions: The Chinese SAD PERSONS Scale is a brief instrument with acceptable psychometric properties for self-harm prediction. However, cautions should be paid to level of therapeutic relationships during assessment, staff workload and adequate training for wider clinical applications. ? 2014 Wu et al.; licensee BioMed Central Ltd.Psychometric properties; Repetition; Self-harm; Suicide risk assessment; Taiwan[SDGs]SDG3adult; article; automutilation; Beck Hopelessness Scale; Chinese SAD PERSONS Scale; controlled study; depression; diagnostic test accuracy study; emergency patient; feasibility study; female; follow up; Hamilton scale; hopelessness; human; major clinical study; male; nursing care; predictive validity; psychometry; rating scale; reliability; risk assessment; satisfaction; sensitivity and specificity; suicidal ideation; Taiwan; validation study; adolescent; emergency health service; receiver operating characteristic; risk factor; Self-Injurious Behavior; suicidal ideation; suicide; Adolescent; Adult; Depression; Emergency Service, Hospital; Female; Humans; Male; Personal Satisfaction; Psychometrics; Risk Assessment; Risk Factors; ROC Curve; Self-Injurious Behavior; Sensitivity and Specificity; Suicidal Ideation; Suicide; Taiwanjournal article10.1186/1471-244X-14-44245335372-s2.0-84896713427
