Disturbances in positive affect and reductions in social reward/interpersonal pleasure are common across a range of clinical disorders and are often related. We examined the relationship between the Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS-A), and other measures of positive affect in adolescents in a genetically informative research design. The sample consisted of 177 MZ and 136 same sex DZ twins drawn from a study of adolescent twins (M = 16.4 ± .97 years) who were part of the Wisconsin Twin Project. The self-report questionnaires included the Behavioral Activation Scale (BAS), Psychological Well-Being Scale, revised Early Adolescent Temperament Questionnaire (EATQR) and the adolescent version of the ACIPS (ACIPS-A). Structural equation modeling estimated the relative contribution of genetic and environmental factors to the phenotypic variance in each of the measures. Follow-up bivariate analyses parsed the genetic and environmental contributions to the phenotypic covariances between the ACIPS-A and each of the other measures of positive affect. We found evidence of moderate heritability for the ACIPS-A scale scores. Overall, models specifying additive genetic and unique environmental effects (AE models) were the most parsimonious models for each of the measures. Several of the measures showed moderate positive phenotypic intercorrelations, and all but one of these intercorrelations showed significant partial genetic underpinnings. Moreover, the bivariate biometric analyses indicated that the ACIPS-A also captures unique heritable variation. Thus, the ACIPS-A captures unique heritable contributions to social/interpersonal pleasure, as well as shared genetic variance with other measures of positive affectivity.
积极情感障碍以及社交奖励/人际愉悦感降低在一系列临床疾病中很常见，且往往相互关联。我们在一项具有遗传信息的研究设计中，考察了青少年预期性和满足性人际愉悦感量表（ACIPS-A）与其他积极情感测量指标之间的关系。样本包括从威斯康星双胞胎项目中抽取的177对同卵双胞胎和136对同性异卵双胞胎，这些青少年双胞胎的年龄为16.4±0.97岁。自我报告问卷包括行为激活量表（BAS）、心理健康量表、修订后的青少年早期气质问卷（EATQR）以及ACIPS青少年版（ACIPS-A）。结构方程模型估计了遗传和环境因素对各测量指标表型变异的相对贡献。后续的双变量分析剖析了遗传和环境因素对ACIPS-A与其他积极情感测量指标之间表型协方差的贡献。我们发现ACIPS-A量表得分存在中度遗传性的证据。总体而言，指定加性遗传和独特环境效应的模型（AE模型）对每个测量指标来说都是最简约的模型。其中几项测量指标显示出中度正表型相关性，除一项外，所有这些相关性均显示出显著的部分遗传基础。此外，双变量生物统计学分析表明，ACIPS-A还捕捉到了独特的遗传变异。因此，ACIPS-A捕捉到了对社交/人际愉悦感的独特遗传贡献，以及与其他积极情感测量指标共享的遗传方差。
