生活目的测试（PIL）是最著名的衡量生活意义的方法，几十年来引起了广泛的关注。本研究旨在确定最优版本的PIL，并探讨其在中文语境下的心理测量特性。本研究以986名中国大学生为研究对象，采用验证性因子分析（CFA）和项目反应理论（IRT）。结果表明，在所有15个PIL版本中，Morgan和Farsides的双因素解决方案（PIL-10）对数据的拟合效果最好。此外，该量表具有良好的信度和效度，在大多数潜在性状范围内具有较高的精度。然而，从类别反应曲线中发现，在某些项目中存在一些有问题的选项。这些发现可作为修订PIL-10的参考。
The Purpose in Life test (PIL) is the best-known measure of meaning in life and has attracted widespread attention for decades. The current study aimed to determine the optimal version of the PIL and to investigate its psychometric properties in the Chinese context. This study was conducted with a Chinese college student sample (N = 986) using confirmatory factor analysis (CFA) and item response theory (IRT). The results indicated that Morgan and Farsides’ two-factor solution (PIL-10) showed the best fit to the data among all fifteen PIL versions. In addition, the PIL-10 was demonstrated to be a cross-culturally sound measure with good reliability and validity and has high precision over most of the latent trait range. However, the findings from category response curves showed some problematic options in some items. These findings may serve as references for revision of the PIL-10.
