N2  - OBJECTIVE: The purpose of this study was to develop an instrument for assessing triggers of suicidal ideation among older outpatients and determine its psychometrics. <br><br>METHOD: Participants were recruited from older outpatients of two hospitals in northern Taiwan. The 34-item Triggers of Suicidal Ideation Inventory (TSII) was developed, and its items were validated by experts in two runs of Delphi technique survey. Pre-testing this TSII in 200 older outpatients resulted in a 12-item TSII, with three items not considered triggers but suggesting the need for further psychiatric assessment. The 9-item TSII was examined by criterion validity, construct validity, internal consistency reliability, and test-retest reliability. <br><br>RESULTS: Factor analysis of the final version of TSII yielded a three-factor solution, accounting for 68.75% of the variance. Participants with depressive tendency tended to have higher TSII scores than participants with no depressive tendency (t = 8.62, p < 0.01), indicating good construct validity. TSII scores were significantly and positively correlated with Beck Scale for Suicide Ideation (r = 0.45, p < 0.01) and UCLA Loneliness (r = 0.55, p < 0.01) scores, indicating satisfactory criterion validity. The TSII had Cronbach's α and intraclass correlation coefficient of 0.70 and 0.99, respectively, indicating acceptable internal consistency reliability and excellent test-retest reliability. Receiver operating characteristic analysis revealed an area under the curve of 0.82, indicating excellent ability to detect triggers of suicidal ideation. With a cutoff point of 2, the sensitivity and specificity were 0.76 and 0.69, respectively. <br><br>CONCLUSIONS: The TSII can be completed in 5 min, is perceived as easy to complete, and yielded highly acceptable parameters of validity and reliability.
