BACKGROUNDS: The Positive and Negative Suicide Ideation (PANSI) Inventory is a widely used self-report questionnaire which is designed to comprehensively evaluate the protective factors and negative risk factors associated with suicidal behaviors among adolescents. The present study aimed to evaluate the psychometric properties and measurement invariance of the Chinese version of the PANSI in a non-clinical sample of Chinese adolescents.
METHODS: Participants (N = 1198) were Chinese middle school students aged 11-17 years (44.8% boys and 51.9% girls, 3.3% missing values) in Guizhou Province. All participants completed the Chinese version of the Positive and Negative Suicide Ideation Inventory (PANSI-C), the Rosenberg self-esteem scale (RSE), and the suicide probability scale (SPS). Cronbach's alpha coefficients, confirmatory factor analysis, Pearson's correlations, and multigroup confirmatory factor analysis tests were conducted thereafter.
RESULTS: The results showed that the Cronbach's alpha coefficients for the two subscales of the PANSI-positive suicide ideation and the PANSI-negative suicide ideation were.696 and.915, respectively. The confirmatory factor analysis supported the fit of the two-factor model as the best fitting model [Chi-square goodness of fit = 703.859, p < .001, degrees of freedom = 76, comparative fit index = .919, Tucker-Lewis index = .903, standardized root mean square residual = .047, root mean square error of approximation (90% CI) = .083 (.077,.089)]. Positive suicide ideation had negative correlations with the SPS and positive correlations with the RSE, whereas the negative suicide ideation had positive correlations with the SPS and negative correlations with the RSE. All correlations were statistically significant (p < .001), demonstrating the criterion validity of the PANSI-C. Moreover, the strict measurement invariance of the PANSI-C was supported across gender, single-parent and non-single-parent households groups, and the strong measurement invariance was supported across age. LIMITATIONS: The feasibility of this study is limited to Chinese normal adolescents and lack of clinical samples.
CONCLUSION: Empirical support for the reliability and validity of the PANSI-C was found. The PANSI-C instrument is found to be useful in assessing positive and negative suicide ideation in Chinese normal adolescents.
