abstract="OBJECTIVE: We provide a brief description of the development of the Trauma and Suicide Potential Index-5 (TSPI-5) and report on the psychometric properties of scores from the new instrument. The TSPI-5 is designed to assess an individual's desire to attempt suicide due to experiencing a trauma. <br><br>METHOD: We examined the structure of the instrument in two independent undergraduate samples. Study 1 (<i>N</i> = 415) examined the structure of the TSPI-5 using exploratory structural equation modeling (ESEM). Study 2 (<i>N</i> = 538) re-examined the instrument structure using the same modeling strategy and also examined other validity estimates. <br><br>RESULTS: Study 1 demonstrated an adequate fit to the sample data (χ2 [1, <i>N</i> = 415] = 215.99, <i>p</i> <.001, CFI = .969, TLI = .939, RMSEA = .319 [90% CI = .283,.356], <i>p</i> <.001) and suggested evidence for unidimensionality. Study 2 confirmed the unidimensionality of the TSPI-5 as shown by acceptable fit estimates to the sample data, <i>χ<sup>2</sup></i> (5, <i>N</i> = 538) = 80.45, <i>p</i> <.001, CFI <i>=</i>.996, TLI = .99, RMSEA = .17 (90% CI = .140,.200), <i>p</i> <.001. Scale reliability estimates for the TSPI-5 were good in Study 1 (omega = .94) and Study 2 (omega = .96). <br><br>CONCLUSION: The TSPI-5 is a brief unidimensional instrument and its scores demonstrated good reliability and validity for assessing suicide-related behaviors due to experiencing a trauma in undergraduate samples.<p /> <p>Language: en</p>",
