本文主要探討潛藏成長模式（Latent growth model, LGM）的檢定力，作為模式修正的參考。潛藏成長模式是近年廣泛被利用於縱貫研究分析的模式之一，潛藏成長模式是從結構化方程式模型（Structural equation models, SEM）的理論架構推導而來。因此本文以Satorra和Saris(1985)所提出的檢定力求算方法，針對潛藏成長模式中平均成長率的因子，進行檢定力研究。了解潛藏變數的變異數、平均成長率、樣本數等影響檢定力的因素對檢定力所造成的影響，並列舉綜合檢定力表供實徵研究參考。

The paper is mainly focus on the discovery of the power of Latent growth model (LGM hereafter) to be used for the reference of model modification .The latent growth models to be studied are much popularized in recent years especially at longitudinal study. Latent growth model was derived from theories of the structural equation models (SEM). This paper is based on the method proposed by Satorra, & Saris in 1985 to make a research for the power of LGM. The power of LGM is varied by three variables, the average growth rate, the variance of latent variables and sample sizes. This paper is to check the impact of these three variables to the power of LGM and tabulate the list of the powers for reference of the further researches.
