本研究估计遗传影响的程度，在58个单卵和46个双卵对成年双胞胎谁是分开抚养的样本中的儿童家庭环境的看法。用于评估家庭环境的措施是家庭环境量表（FES）和街区环境问卷（BEQ）。主成分因子分析与VARIMAX旋转的FES和BEQ产生2个主要因素-支持，组织和文化导向。单指标和多指标模型拟合技术被应用于分开饲养的双胞胎数据的2个因素。感知支持在童年的家庭环境中拟合最好的模型，将添加剂的遗传和非共享的环境因素。感知组织最适合的模型，其中只包括非共享的环境因素。最大似然估计的遗传模型拟合分析表明，遗传因素解释44%的方差的看法，在童年的家庭环境中的支持维度。
This study estimates the extent to which heredity influences perceptions of childhood family environment in a sample of 58 monozygotic and 46 dizygotic pairs of adult twins who were reared apart. The measures used to assess family environments were the Family Environment Scale (FES) and Block Environmental Questionnaire (BEQ). A principal component factor analysis with a VARIMAX rotation of the FES and BEQ yielded 2 major factors--Support, and Organization and Cultural Orientation. Single and multiple indicator model-fitting techniques were applied to the reared apart twin data on the 2 factors. Perceived support in childhood family environments was fitted best by a model incorporating additive genetic and unshared environmental factors. Perceived organization was fitted most adequately by a model which includes only unshared environmental factors. Maximum-likelihood estimates of heritability from model-fitting analyses suggest that genetic factors explain 44% of the variance of perceptions of support dimension in childhood family environments.
