The unidimensional model of acculturation posits that heritage and mainstream culture identifications have a strong inverse relation, whereas the bidimensional model posits that the 2 identifications are independent. The authors compared these models in 3 samples of ethnic Chinese (ns = 164, 150, and 204), 1 sample of non-Chinese East Asians (n = 70), and one diverse group of acculturating individuals (n = 140). Although the unidimensional measure showed a coherent pattern of external correlates, the bidimensional measure revealed independent dimensions corresponding to heritage and mainstream culture identification. These dimensions displayed patterns of noninverse correlations with personality, self-identity, and psychosocial adjustment. The authors conclude that the bidimensional model is a more valid and useful operationalization of acculturation.
文化适应的单维模型假定，传统文化和主流文化认同之间存在强烈的反向关系，而二维模型则假定这两种认同是相互独立的。作者在3个华裔样本（样本量分别为164、150和204）、1个非华裔东亚人样本（样本量为70）以及1个由不同文化适应个体组成的样本（样本量为140）中对这些模型进行了比较。尽管单维测量显示出与外部相关因素的连贯模式，但二维测量揭示了与传统文化和主流文化认同相对应的独立维度。这些维度呈现出与人格、自我认同和心理社会适应的非反向相关模式。作者得出结论，二维模型是对文化适应更有效且有用的一种操作化方式。
