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.

化学感官愉悦量表：一种用于测量享乐感和味觉能力的新评估。

快感缺乏症或无法享受愉悦感是许多精神障碍（例如抑郁症和精神分裂症）的关键临床特征。尽管存在各种关于快感不足和愉悦体验的有效测量方法，但尚无用于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）来评估享乐对于嗅觉和味觉愉悦的能力。我们在研究中检查了CPS的可靠性和有效性。首先，我们进行了探索性因素分析（EFA）和确认性因素分析（CFA），以识别和检查CPS的结构。其次，研究了CPS的有效性和重测稳定性。CPS与对快感不足和愉悦体验的其他测量结果相关。此外，在我们的研究中还检验了CPS的经验有效性。结果表明，CPS是评估个人在非临床样本中享乐享乐能力的可靠且有效的量度。本文还讨论了CPS在各种人群中的进一步应用，尤其是对于患有精神疾病（例如抑郁症，精神分裂症和自闭症）的患者。
