以往关于患者健康问卷（PHQ-9）的析因结构的研究得出了不同的结果，并且对于哪种析因结构提供更充分的拟合并没有达成共识。在哥伦比亚，没有使用精确的方法来估计PHQ-9的析因结构。本研究的目的是通过先前研究的两个因素模型来评估PHQ-9作为哥伦比亚大学生抑郁症筛查工具的析因结构。采用PHQ-9量表对550名卫生科学专业大学生进行了问卷调查。使用结构方程模型和不变性分析进行了析因验证分析。一个体细胞因子和一个非体细胞因子的模型在性别不变性方面取得了较好的拟合效果。PHQ-9在卡塔赫纳市大学生中作为抑郁筛查工具，揭示了躯体和非躯体两个因素，且测量结果在性别上具有不变性。
Previous studies on the factorial structure of the Patient Health Questionnaire (PHQ-9) have yielded divergent results, and there is no consensus on which factorial structure provides a more adequate fit. In Colombia, no precise method to estimate the factorial structure of the PHQ-9 has been used. The purpose of this study is to evaluate the factorial structure of the PHQ-9 as a depression screening tool in university students of Colombia from a model of two factors previously studied. The PHQ-9 was applied to 550 health science university students. A factorial confirmatory analysis was carried out using a structural equations model and invariance analysis. The model with one somatic factor and one non-somatic factor, achieved a better fit with invariance by gender. The PHQ-9 used as a depression screening tool used in university students in Cartagena revealed two factors, one somatic and one non-somatic with measurement invariance by gender.
