背景最近的研究表明，快感缺乏，无法体验快乐，可以作为一个持久的特质，在非临床样本。为了检查特质快感缺失的非临床样本，我们研究了广泛使用的问卷调查捕获快感缺失的范围内的属性。方法对887名大学生进行问卷调查。采用查普曼社会性快感缺乏量表（CRSAS）、查普曼身体性快感缺乏量表（CPAS）、时间性快感体验量表（TEPS）和分裂型人格问卷（SPQ）进行调查。结果男性躯体性快感缺乏（F = 5.09，p<0.001）和社会性快感缺乏（F = 4.38，p<0.005）均显著高于女性。 与预期的一样，具有典型人格特征的个体在躯体性（t = 3.81，p<0.001）和社会性（t = 7.33，p<0.001）特质快感缺失上的得分也显著高于不具有SPD特征的个体，但在自我报告的预期性和完成性快感体验上没有差异。 结论在躯体性和社会性快感缺失各条目的比较中，具有SPD特征的个体在社会性快感缺失的条目数上高于无SPD特征的个体。这些初步研究结果表明，特质性快感缺乏可以被鉴定为非临床样本。探索一般人群中特质快感缺失的人口统计学和临床相关性可能为精神障碍的发病机制提供线索。
Background Recent studies suggest that anhedonia, an inability to experience pleasure, can be measured as an enduring trait in non-clinical samples. In order to examine trait anhedonia in a non-clinical sample, we examined the properties of a range of widely used questionnaires capturing anhedonia. Methods 887 young adults were recruited from colleges. All of them were administered a set of checklists, including Chapman Scale for Social Anhedonia (CRSAS) and the Chapman Scale for Physical Anhedonia Scale (CPAS), The Temporal Experience of Pleasure Scale(TEPS), and The Schizotypal Personality Questionnaire (SPQ). Results Males showed significantly higher level of physical (F = 5.09, p<0.001) and social (F = 4.38, p<0.005) anhedonia than females. As expected, individuals with schizotypal personality features also demonstrated significantly higher scores of physical (t = 3.81, p<0.001) and social (t = 7.33, p<0.001) trait anhedonia than individuals without SPD features, but no difference on self-report anticipatory and consummatory pleasure experience. Conclusions Concerning the comparison on each item of physical and social anhedonia, the results indicated that individuals with SPD feature exhibited higher than individuals without SPD features on more items of social anhedonia than physical anhedonia scale. These preliminary findings suggested that trait anhedonia can be identified a non-clinical sample. Exploring the demographic and clinical correlates of trait anhedonia in the general population may provide clues to the pathogenesis of psychotic disorder.
