Morningness-Eveningness Stability Scale improved (MESSi) is a newly constructed measure to assess circadian types and amplitude. In this study, we applied this measure to participants from three different countries: Germany, Spain and Iran. Confirmatory factorial analysis (CFA) of MESSi displayed mediocre fit in the three countries. Comparing increasingly stringent models using multigroup confirmatory factor analyses indicated at least partial measurement invariance (metric invariance) by country for Morning Affect and Distinctness subscales. Age was positively related to Morning Affect (MA), and negatively related to Eveningness (EV) and Distinctness (DI). Men reported higher MA than women, whereas women reported higher DI than men. Regarding country effect, Iranian participants reported highest MA compared to Spaniards and Germans, whereas Germans reported higher DI compared to Iranians and Spaniards. As a conclusion, our study corroborated the validity and reliability of MESSi across three different countries with different geographical and cultural characteristics.
晨型-夜型稳定性量表改进版（MESSi）是一种新构建的用于评估昼夜节律类型和幅度的测量工具。在本研究中，我们将该测量工具应用于来自三个不同国家的参与者：德国、西班牙和伊朗。MESSi的验证性因子分析（CFA）在这三个国家显示出中等拟合度。使用多组验证性因子分析比较越来越严格的模型表明，晨型情感和清晰度子量表在不同国家至少具有部分测量不变性（度量不变性）。年龄与晨型情感（MA）呈正相关，与夜型（EV）和清晰度（DI）呈负相关。男性报告的MA高于女性，而女性报告的DI高于男性。关于国家效应，与西班牙人和德国人相比，伊朗参与者报告的MA最高，而与伊朗人和西班牙人相比，德国人报告的DI更高。总之，我们的研究证实了MESSi在具有不同地理和文化特征的三个不同国家的有效性和可靠性。
