The goals of the study were to determine the extent to which the underlying structure of different types of well-being was multidimensional and whether well- and ill-being were influenced by similar or different genetic and environmental factors. Participants were 1226 male twins ages 51-60, from the Vietnam Era Twin Study of Aging. Measures included: psychological well-being, Multidimensional Personality Questionnaire Well-Being scale (MPQWB), life satisfaction, self-esteem, and depressive symptoms. A two-orthogonal-factor common pathway model fit the data well. Psychological well-being and self-esteem loaded most strongly on Factor 1, which was highly heritable (h(2) = .79). Life satisfaction loaded most strongly on Factor 2, which was only moderately heritable (h(2) = .32). Only MPQWB had measure-specific genetic influences. Depressive symptoms loaded on both factors, and only depressive symptoms had measure-specific common environmental influences. All measures had specific unique environmental influences. Results indicate that well-being is genetically and environmentally multidimensional and that ill-being has partial overlap with both latent factors.
这项研究的目的是确定不同类型的幸福感的潜在结构在多大程度上是多维的，以及幸福感和不幸福感是否受到相似或不同的遗传和环境因素的影响。参与者是来自越南时代老化双胞胎研究的 1226 名年龄在 51-60 岁的男性双胞胎。测量包括：心理幸福感、多维人格问卷幸福感量表（MPQWB）、生活满意度、自尊和抑郁症状。一个两正交因子共同途径模型很好地拟合了数据。心理幸福感和自尊主要加载在第一个因子上，该因子具有高度遗传性（h(2) = 0.79）。生活满意度主要加载在第二个因子上，该因子只有中度遗传性（h(2) = 0.32）。只有 MPQWB 具有特定的遗传影响。抑郁症状同时加载在两个因子上，只有抑郁症状具有特定的共同环境影响。所有的措施都有特定的独特的环境影响。研究结果表明，幸福感在遗传和环境上是多维的，而不幸福感与两个潜在因素部分重叠。
