N2  - PURPOSE: To evaluate the psychometric properties of a 9-item Concise Health Risk Tracking Self-Report (or CHRT-SR(9)) to assess suicidal risk in adult primary care outpatients. <br><br>METHODS: Overall, 369 adults completed the original 14-item version of CHRT-SR at baseline and within 4 months thereafter, from which the CHRT-SR(9) was extracted using multigroup confirmatory factor analysis. Measurement invariance (across age and sex) and classical test theory characteristics of the CHRT-SR(9) were evaluated. Concurrent validity was assessed by comparing CHRT-SR(9) responses to those of the suicide item in the Patient Health Questionnaire (PHQ-9), both cross-sectionally and as a change measure over time. <br><br>RESULTS: Confirmatory factor analysis identified the CHRT-SR(9) as the optimal solution. Factors included pessimism, helplessness, despair (2 items each) and suicidal thoughts (3 items). Measurement invariance held across sex and age groups, indicating that mean differences among sub-groups were real and not attributable to measurement bias. Classical test theory revealed acceptable item-total correlations overall (0.57-0.79) and internal consistency (Spearman-Brown from 0.76 to 0.90). Concurrent validity analyses revealed that the CHRT-SR(9) can measure both improvement and worsening of suicidality over time. A PHQ-9 response of 0, 1, 2, and 3 on the suicide item corresponded to 7.82 (5.53), 16.80 (4.99), 20.71 (5.36), and 25.95 (7.30) (mean and SD) on CHRT-SR(9) total score, respectively. <br><br>CONCLUSION: The CHRT-SR(9) is a brief self-report evaluating suicidality with excellent psychometric properties that is sensitive to change over time.<p />  <p>Language: en</p>
