本研究的目的是调查在一个较老的巴西队列中收集的关于简易精神状态检查(MMSE)结构的纵向数据是否支持因素随时间的不变性。设计分析来自一项基于社区的队列研究的10年数据。研究地点在巴西班布伊。参与者研究样本包括1558名(89.4%)所有符合条件的1742名老年居民。测量使用了MMSE的巴西标准版本。结果在队列基线上开发的五因素解决方案提供了一个合理的适合MMSE的解决方案，无论是没有限制或负荷限制随时间相等。两种模型的比较表明，没有约束的模型更优越。然而，5个绝对拟合度指数表明，完全约束模型也是足够的，与没有任何限制的模型没有实质性差异。结论MMSE的结构在10个测量时间内保持相对不变，从而为该量表的良好结构效度提供了证据。版权所有(C)2014 John Wiley&Sons，Ltd.
ObjectiveThe study aims to investigate whether longitudinal data on the structure of the mini mental state examination (MMSE) collected in an older Brazilian cohort support factorial invariance over time.DesignAnalysis of 10-year data from a community-based cohort study was performed.SettingThe study took place in Bambui, Brazil.ParticipantsThe study sample comprised 1558 (89.4%) of all eligible 1742 elderly residents.MeasurementsA standard Brazilian version of the MMSE was used.ResultsA five-factor solution (developed on the baseline of the cohort) either with no constraints or with loadings constrained to equality across time provided a reasonable fit for the MMSE. A comparison between both models suggested that the model with no constraints was superior. However, the five absolute goodness-of-fit indices suggest that the fully constrained model was also adequate and did not differ substantively from the model without any restriction.ConclusionThe structure of the MMSE remained relatively unchanged across the 10 measurement times, thus providing evidence for the good construct validity of the scale across time.
