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.
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.
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.
The feasibility of this study is limited to Chinese normal adolescents and lack of clinical samples.
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.
正负性自杀观念问卷（PANSI）是一种广泛使用的自陈式问卷，旨在全面评估青少年自杀行为相关的保护因素和负面风险因素。本研究旨在评估中文版PANSI在非临床样本的中国青少年中的心理测量学特性和测量不变性。
参与者（N = 1198）为贵州省11至17岁的中国中学生（男生占44.8%，女生占51.9%，缺失值占3.3%）。所有参与者均完成了中文版正负性自杀观念问卷（PANSI-C）、罗森伯格自尊量表（RSE）和自杀概率量表（SPS）。随后进行了克朗巴哈系数分析、验证性因素分析、皮尔逊相关性分析和多组验证性因素分析测试。
结果显示，PANSI的两个子量表——正性自杀观念和负性自杀观念的克朗巴哈系数分别为0.696和0.915。验证性因素分析支持两因素模型为最佳拟合模型[卡方拟合优度 = 703.859，p < 0.001，自由度 = 76，比较拟合指数 = 0.919，塔克-刘易斯指数 = 0.903，标准化均方根残差 = 0.047，近似误差均方根（90%置信区间） = 0.083（0.077，0.089）]。正性自杀观念与SPS呈负相关，与RSE呈正相关，而负性自杀观念与SPS呈正相关，与RSE呈负相关。所有相关性均具有统计学意义（p < 0.001），证明了PANSI-C的效标效度。此外，PANSI-C在性别、单亲家庭与非单亲家庭组间支持严格测量不变性，在年龄组间支持强测量不变性。
本研究的可行性仅限于中国正常青少年，缺乏临床样本。
研究发现了支持PANSI-C信效度的实证依据。发现PANSI-C工具可用于评估中国正常青少年的正负性自杀观念。
