无法体验快乐，快感缺乏，被认为是抑郁症的标志性症状。一个工具开发的享乐能力的评估是14个项目，自我报告，Snaith-Hamilton快乐量表，但其心理测量特性尚未得到充分的评价。本研究采用大样本的成人门诊抑郁症（MDD）患者检验SHAPS的信度和效度。本研究的数据来自461例诊断为MDD的成人门诊患者，他们参加了IMPLENT项目。使用Cronbach系数α评估SHAPS的内部一致性。主因子分析被用来定义的SHAPS的维度。通过评估SHAPS总分与IDS-C30、QLES-Q、HRSD 17、IDS-C30、QIDS-C16和MADRS 10的快乐/享受项目之间的Pearson相关性来评估收敛效度和判别效度。SHAPS的内部一致性为0.91。一个单因素的解决方案出现的SHAPS（前两个初始因素的特征值分别为5.95和0.43）。Pearson相关性显示SHAPS总分与HRSD 17（r = .49，p<.0001）、IDS-C30（r = .56，p<.0001）、QIDS-C16（r = .55，p<.0001）和MADRS 10（r = .53，p<.0001）总分之间存在正线性关系。SHAPS总分与QLES-Q呈负相关（r =-0.65，p<.0001）。目前的研究表明，SHAPS是一个可靠的，有效的，和一维的工具，以评估成人门诊MDD患者的享乐能力。
The inability to experience pleasure, anhedonia, is recognized as a hallmark symptom of depression. An instrument developed for the assessment of hedonic capacity is the 14-item, self-report, Snaith–Hamilton Pleasure Scale, but its psychometric properties have not been adequately evaluated. The current study examined the reliability and validity of the SHAPS using a large sample of adult outpatients with major depressive disorder (MDD). Data for the current study were obtained from 461 adult outpatients with a diagnosis of MDD who participated in Project IMPACTS. Internal consistency of the SHAPS was assessed using Cronbach’s coefficient alpha. A Principal Factor Analysis was used to define the dimensionality of the SHAPS. Convergent and discriminant validity was assessed by evaluating the Pearson correlations between the SHAPS total score and the pleasure/enjoyment item of the IDS-C30, QLES-Q, HRSD17, IDS-C30, QIDS-C16, and MADRS10, respectively. The internal consistency of the SHAPS was .91. A one-factor solution emerged for the SHAPS (eigenvalues of the first two initial factors were 5.95 and 0.43, respectively). Pearson correlations revealed a positive linear relationship between the SHAPS total score and the total scores on the HRSD17 (r = .49, p<.0001), IDS-C30 (r = .56, p<.0001), QIDS-C16 (r = .55, p<.0001), and MADRS10 (r = .53, p<.0001). The SHAPS total score was negatively correlated with the QLES-Q (r = -0.65, p<.0001). The current study shows that the SHAPS is a reliable, valid, and unidimensional instrument to assess hedonic capacity in adult outpatients with MDD.
