Using a measure of capacity for pleasurable experiences (the Pleasure Scale), the authors compared at admission and 7-month follow-up 74 psychiatric inpatients meeting DSM-III criteria for major depression. Pleasure scores were stable over 7 months despite the fact that two-thirds of the sample recovered from depression. The subgroup of subjects who were most anhedonic at admission were more likely than the remaining subjects to show clinical recovery but persisted in exhibiting a lower pleasure score (even when the comparison was limited to recovered subjects). Pleasure scores were much better predictors of clinical recovery than were neuroticism scores.
作者使用一种衡量愉悦体验能力的量表（愉悦量表），在入院时和7个月随访时对74名符合《精神疾病诊断与统计手册》第三版（DSM-III）重度抑郁症标准的精神科住院患者进行了比较。尽管三分之二的样本从抑郁症中康复，但愉悦得分在7个月内保持稳定。入院时最缺乏快感的受试者亚组比其余受试者更有可能实现临床康复，但仍表现出较低的愉悦得分（即使比较仅限于康复的受试者）。与神经质得分相比，愉悦得分是临床康复更好的预测指标。
