The study aimed to determine the dimensionality of the Spanish version of the PQ-16 among Colombian adolescent school students.
A validation study was designed with the participation of 334 Colombian adolescent students aged between 13 and 17 (M = 15.2, SD = 1.1); 171 (52.1%) were girls, and 163 (47.9%) were boys, 229 (68.6%) were ninth-grade students and 105 (31.4%) were tenth-grade students. Confirmatory factor analysis was performed, internal consistency was calculated with the Kuder-Richardson and McDonald's omega tests, and correlation with suicide ideation was computed with the Kendall correlation (r).
The confirmatory factor analysis showed that the PQ-16 adequately fit a unidimensional structure: RMSEA = 0.05 (90%CI 0.04-0.06), CFI = 0.91, TLI = 0.90, SRMR = 0.05, chi-squared = 193.18 (df = 102, p < 0.001) and normalized chi-squared = 1.89. This factor presented high internal consistency: Kuder-Richardson test and McDonald's omega of 0.83. The correlation between the PQ-16 and suicide ideation was r = 0.45 (p < 0.001).
The PQ-16 is a one-dimensional tool with high internal consistency and correlation with suicide ideation among schooled adolescents. Further research should explore the PQ-16 performance against a structured clinical interview.
本研究旨在确定哥伦比亚青少年学生中西班牙语版PQ - 16的维度。
设计了一项验证性研究，有334名年龄在13至17岁之间的哥伦比亚青少年学生参与（M = 15.2，标准差 = 1.1）；其中171名（52.1%）为女生，163名（47.9%）为男生，229名（68.6%）为九年级学生，105名（31.4%）为十年级学生。进行了验证性因素分析，使用库德 - 理查森和麦克唐纳ω检验计算内部一致性，并使用肯德尔相关性（r）计算与自杀意念的相关性。
验证性因素分析表明，PQ - 16充分拟合单维结构：均方根误差近似值（RMSEA） = 0.05（90%置信区间0.04 - 0.06），比较拟合指数（CFI） = 0.91，塔克 - 刘易斯指数（TLI） = 0.90，标准化残差均方根（SRMR） = 0.05，卡方值 = 193.18（自由度 = 102，p < 0.001），标准化卡方值 = 1.89。该因素具有较高的内部一致性：库德 - 理查森检验和麦克唐纳ω值为0.83。PQ - 16与自杀意念之间的相关性为r = 0.45（p < 0.001）。
PQ - 16是一种具有高内部一致性且与在校青少年自杀意念相关的单维工具。进一步的研究应探索PQ - 16在结构化临床访谈中的表现。
