用关系量表问卷（RSQ）对220对成年双胞胎（116对同卵双胞胎）的志愿者样本数据进行了成人依恋类型的遗传性评估。104对异卵)。累加性遗传效应分别占安全型、恐惧型和专注型成人依恋类型差异的37%、43%和25%，但对回避型没有影响。在所有类型的差异中，非共享环境影响占了大部分：63%是安全的，57%是害怕的。75%的人在忙，71%的人在偷懒。除了解雇（29%）之外，所有风格的共同环境影响都可以忽略不计。
The heritability of adult attachment styles as measured by the Relationship Scales Questionnaire (RSQ) was estimated on data from a volunteer general population sample of 220 adult twin pairs (116 monozygotic pairs. 104 dizygotic pairs). Additive genetic effects accounted for 37%, 43%,and 25% of the variance in the secure, fearful, and preoccupied adult attachment styles, respectively, but none of the variance in the dismissing style. Nonshared environmental influences accounted for the majority of the variance in all styles: 63% secure, 57% fearful. 75% preoccupied, and 71% dismissing. Shared environmental effects were negligible far all styles except dismissing (29%).
