Domains Of Pleasure Scale (DOPS): assessing pleasure across domains

Anhedonia, or loss of pleasure, is a multifaceted construct that has been shown challenging to measure. The Domains Of Pleasure Scale (DOPS) is a newly developed questionnaire designed to measure the multifaceted aspects of pleasure. It assesses levels of pleasure across different domains (e.g., social, physical). The psychometric properties of the DOPS were tested in two studies (Study 1: N = 2937, Mage = 21.4 years, SD = 1.9; Study 2: N = 1187, Mage = 22.84, SD = 2.23). In line with the multifaceted view of pleasure experiences, comparisons with a one factor solution showed that pleasure may be best investigated domain specific rather than aggregated over all items. Across studies, exploratory and confirmatory factor analysis showed that pleasure was reliably measured in the domains of social pleasure, sexual pleasure, perceptual pleasure, and pleasure in personal achievements. Measurement invariance was established across sex and educational level in Study 1, but not in Study 2. The DOPS is a promising instrument to measure pleasure across different domains and may help researchers and clinicians to pinpoint interventions.

厌恶性，或称愉悦感的丧失，是一个具有多维度特征的复杂结构，其测量一直被视为一项挑战。愉悦领域量表（DOPS）是一项新近开发的问卷，旨在测量愉悦感的多维度特征。该量表评估了愉悦感在不同领域（例如，社交、身体）的水平。DOPS的心理测量学特性在两项研究中得到了检验（研究1：N = 2937，平均年龄 = 21.4岁，标准差 = 1.9；研究2：N = 1187，平均年龄 = 22.84岁，标准差 = 2.23）。与单一因素解决方案的比较表明，愉悦感的研究或许更适宜于特定领域而非将所有项目汇总。在跨研究分析中，探索性因素分析和验证性因素分析均表明，愉悦感在社会愉悦、性愉悦、感知愉悦和个人成就愉悦等领域得到了可靠的测量。在研究1中，测量不变性在性别和教育水平上得到了证实，但在研究2中并未得到证实。DOPS是一种有潜力的测量不同领域愉悦感的工具，可能有助于研究人员和临床医生精准定位干预措施。
