A community sample of 88 putative schizotypes (48 social anhedonics, 40 controls), aged 18 to 19 years, and their biological parents (42 mothers of social anhedonics, 37 mothers of controls; 24 fathers of social anhedonics, 20 fathers of controls) receive videotaped diagnostic evaluations that serve as the basis for ratings of behavioral signs of schizoidia and schizotypy. Proband social anhedonics exhibit more atypical interpersonal behaviors characteristic of schizoid and schizotypal personality disorders than controls. Mothers of social anhedonics display more atypical interpersonal behaviors characteristic of schizotypal personality disorder than mothers of controls. In contrast, clinical symptom ratings of schizotypy do not differentiate mothers of social anhedonics from mothers of controls. Meaningful, though not statistically significant, effects are observed for behavioral sign ratings in the smaller sample of fathers of social anhedonics. Results provide preliminary support for the familiality of atypical interpersonal behavior in social anhedonics.
选取了一个由88名假定的分裂型人格障碍患者（48名社交快感缺乏者，40名对照者）组成的社区样本，年龄在18至19岁之间，以及他们的亲生父母（42名社交快感缺乏者的母亲，37名对照者的母亲；24名社交快感缺乏者的父亲，20名对照者的父亲），对他们进行录像诊断评估，这些评估作为评定精神分裂症样和分裂型人格障碍行为体征的依据。先证者社交快感缺乏者比对照者表现出更多精神分裂症样和分裂型人格障碍特有的非典型人际行为。社交快感缺乏者的母亲比对照者的母亲表现出更多分裂型人格障碍特有的非典型人际行为。相比之下，分裂型人格障碍的临床症状评分并不能区分社交快感缺乏者的母亲和对照者的母亲。在社交快感缺乏者父亲的较小样本中，行为体征评分观察到了有意义但无统计学显著性的效应。结果为社交快感缺乏者中非典型人际行为的家族性提供了初步支持。
