Recent research has distinguished between anticipatory and consummatory pleasure. In the current study, we examined the psychometric properties of the Temporal Experience of Pleasure Scale (TEPS) to determine whether reliability and validity findings reported in previous research replicate in an additional sample of schizophrenia patients. Participants included 86 individuals with schizophrenia and 59 demographically matched healthy controls. Inconsistent with previous research, patients differed from controls in their reports of consummatory (TEPS-CON), but not anticipatory (TEPS-ANT) pleasure. We also failed to replicate some important correlational findings reported in previous research indicating relationships between the TEPS-ANT subscale and external validators. Analyses of the stability of the TEPS subscales were conducted in a sub-group of patients (n=19), and indicated excellent stability for the TEPS-CON (ICC (intraclass correlation coefficient)=0.93), but somewhat lower stability for the TEPS-ANT subscale (ICC=0.74). These findings suggest that additional studies are needed using the TEPS, as well as other measures, to determine the nature of anhedonia in individuals with schizophrenia.
最近的研究区分了预期和享受的快乐。在当前的研究中,我们检验了时间体验快乐量表(TEPS)的心理测量学特性,以确定在另外一组精神分裂症患者样本中,先前研究报告的可靠性和有效性发现是否可以复制。参与者包括 86 名精神分裂症患者和 59 名人口统计学匹配的健康对照者。与先前的研究不一致的是,患者在报告享受(TEPS-CON)方面与对照组不同,但在预期(TEPS-ANT)方面没有不同。我们也未能复制先前研究报告的一些重要相关发现,这些发现表明 TEPS-ANT 分量表与外部效标之间的关系。在一组患者(n=19)中进行了 TEPS 分量表稳定性的分析,结果表明 TEPS-CON 的稳定性非常好(ICC(组内相关系数)=0.93),但 TEPS-ANT 分量表的稳定性稍差(ICC=0.74)。这些发现表明,需要使用 TEPS 以及其他措施进行更多的研究,以确定精神分裂症个体快感缺失的性质。
