Anhedonia, or the inability to experience pleasure, is a key clinical feature of many mental disorders such as depression and schizophrenia. Although various valid measurements of anhedonia and pleasure experience exist, no scales exist that quantify smell and taste pleasure experiences. The Chemosensory Pleasure Scale (CPS) was therefore designed to assess the hedonic capacity for smell and taste pleasure. We examined the reliability and validity of the CPS in our study. First, we conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to identify and examine the structure of the CPS. Second, the CPS's validity and test-retest stability were investigated. The CPS was correlated with other measurements of anhedonia and pleasure experience. Furthermore, the empirical validity of CPS was also examined in our study. The results indicated that the CPS is a reliable and valid measure for assessing an individual's hedonic capacity for smell and taste pleasure in nonclinical samples. Further application of the CPS for various populations is also discussed herein, especially for patients with mental disorders such as depression, schizophrenia, and autism.
快感缺失，或无法体验愉悦，是许多精神障碍（如抑郁症和精神分裂症）的一个关键临床特征。尽管存在各种有效的快感缺失和愉悦体验测量方法，但不存在量化嗅觉和味觉愉悦体验的量表。因此，设计了化学感觉愉悦量表（CPS）来评估嗅觉和味觉愉悦的愉悦能力。我们在研究中检验了 CPS 的可靠性和有效性。首先，我们进行了探索性因素分析（EFA）和验证性因素分析（CFA），以确定和检验 CPS 的结构。其次，研究了 CPS 的有效性和重测稳定性。CPS 与其他快感缺失和愉悦体验的测量方法相关。此外，我们还在研究中检验了 CPS 的实证有效性。结果表明，CPS 是一种可靠且有效的测量工具，可用于评估非临床样本中个体对嗅觉和味觉愉悦的愉悦能力。本文还讨论了 CPS 在各种人群中的进一步应用，特别是在患有精神障碍（如抑郁症、精神分裂症和自闭症）的患者中。
