A multivariate independent pathway model was used to examine the shared and unique genetic and environmental influences of Positive Affect (PA), Negative Affect (NA), and effortful control (EC) in a sample of 686 twin pairs ( age = 10.07, = 1.74). There were common genetic influences and nonshared environmental influences shared across all three temperament dimensions and shared environmental influences in common to NA and EC. There were also significant independent genetic influences unique to PA and NA and significant independent shared environmental influences unique to PA. This study demonstrates that there are genetic and environmental influences that affect the covariance among temperament dimensions as well as unique genetic and environmental influences that influence the dimensions independently.
采用多元独立路径模型，在一个由686对双胞胎组成的样本（年龄 = 10.07，标准差 = 1.74）中，检验积极情绪（PA）、消极情绪（NA）和努力控制（EC）的共同和独特的遗传及环境影响。在所有三个气质维度中存在共同的遗传影响和非共享环境影响，以及NA和EC共有的共享环境影响。此外，PA和NA还存在显著的独立遗传影响，PA存在显著的独立共享环境影响。本研究表明，存在影响气质维度间协方差的遗传和环境影响，以及独立影响各维度的独特遗传和环境影响。
