Early identification of individuals at risk is critical for suicide prevention. The present study revised the 5-item Brief Symptom Rating Scale (BSRS-5) to a checklist format (BSRS-5R) and validated the BSRS-5R into a screening tool for psychiatric morbidity and suicide ideation in the general public. Methods: The study participants consisted of two subsets of sample from community residents and psychiatric patients. The community subjects were recruited from stratified proportional randomization sampling in a nationwide community survey, while the psychiatric patients were from psychiatric outpatient service and psychiatric daycare unit in a teaching hospital in northern Taiwan. All participants responded to the questionnaire investigating the BSRS-5, personal experience with suicide, and demographic information. Results: In total, 2147 community respondents and 700 respondents from psychiatric settings completed the survey questions. The BSRS-5R was highly correlated to BSRS-5 with good internal consistency in our study sample. For the community subjects, receiver operating characteristic curve analysis revealed an optimal cutoff of 2/3 for BSRS-5R to discriminate psychiatric morbidity or suicide ideation. The BSRS-5R could also identify psychiatric morbidity in psychiatric outpatients and daycare patients. In addition, the cutoff of 4/5 for BSRS-5R to determine suicide ideation yielded moderately good predictive validity in psychiatric outpatients and in daycare patients. Conclusion: The BSRS-5R was validated as an efficient checklist to screen for psychiatric morbidity and suicide ideation in the general public. The result is valuable in translating into general medical and community settings for early detection of suicide ideation. ? 2015.[SDGs]SDG3[SDGs]SDG10[SDGs]SDG16adolescent; adult; aged; anxiety disorder; Article; Brief Symptom Rating Scale; checklist; community; correlation analysis; cross-sectional study; demography; depression; diagnostic accuracy; diagnostic test accuracy study; disease association; false negative result; false positive result; female; hostility; human; insomnia; internal consistency; major clinical study; male; mental disease; mental patient; middle aged; outpatient; population; predictive validity; questionnaire; receiver operating characteristic; reliability; risk assessment; screening; sensitivity and specificity; statistical analysis; suicidal ideation; Taiwan; teaching hospital; checklist; mass screening; Mental Disorders; morbidity; procedures; psychological rating scale; risk factor; self report; standards; statistical model; suicidal ideation; validation study; young adult; Adolescent; Adult; Aged; Checklist; Female; Humans; Logistic Models; Male; Mass Screening; Mental Disorders; Middle Aged; Morbidity; Outpatients; Psychiatric Status Rating Scales; Risk Factors; ROC Curve; Self Report; Suicidal Ideation; Taiwan; Young Adultjournal article10.1016/j.jfma.2015.05.004261417062-s2.0-84933565500
