A psychometric assessment was conducted on a slightly revised version of the Purpose in Life Test (PIL-R). Factor analyses revealed a large general factor plus four primary factors comprising lack of purpose in life, positive sense of purpose, motivation for meaning, and existential confusion. Validity models showed that the PIL-R was positively related to a construct of happiness and was negatively related to suicidality and meaninglessness. Reliability estimates ranged from 0.78 to 0.86. The revised version can be presented compactly and may be less confusing to subjects than the original PIL.
对生活目的测试（PIL-R）的一个稍作修订的版本进行了心理测量评估。因素分析揭示了一个大的一般因素以及四个主要因素，包括生活缺乏目的、积极的目的感、意义动机和存在性困惑。效度模型表明，PIL-R与幸福结构呈正相关，与自杀倾向和无意义感呈负相关。信度估计值在0.78至0.86之间。修订版可以简洁呈现，并且可能比原始的PIL对受试者来说不那么令人困惑。
