The Temporal Experience of Pleasure Scale (TEPS) is a self-report measure designed to assess anticipatory and consummatory pleasure, two facets of anhedonic predispositions. Despite its widespread use, the factor structure of the TEPS has yet to be tested in adolescents, who are at increased risk for psychopathology and undergoing rapid changes in reward-related processes. In response, the present study aimed to test the factor structure and measurement invariance of the TEPS across time, gender, and race/ethnicity in a diverse adolescent sample. Adolescents (N = 441; M_age = 14.98; 223 female) who identified as either Black (37%), Hispanic (37%), or White (26%), completed the TEPS at Baseline, 6-month, and 12-month follow-ups. Factor analyses were conducted to examine the factor structure of the TEPS, while configural, metric, scalar, and strict invariance were tested across time and demographics. Findings supported the two-factor structure of the TEPS, above and beyond other conceptualizations (e.g., 4-factor, bifactor), full longitudinal invariance, and partial invariance across gender and race/ethnicity. Examination of mean differences suggested no temporal, gender nor race/ethnic differences for anticipatory pleasure. For consummatory pleasure, no differences were found for gender, but results suggested higher levels over time and lower levels in Black adolescents. Our findings provide preliminary support for reliable cross-group interpretations of anticipatory and consummatory anhedonic predispositions as measured through the TEPS. Together, results provide support for the clinical utility of the TEPS for anhedonic-related psychopathology risk assessment in adolescence.

跨时间、性别和种族/民族测试青少年快乐量表时间体验的因子结构和测量不变性。

快乐的时间体验量表 (TEPS) 是一种自我报告的测量方法，旨在评估预期和完成的快乐，这是快感倾向的两个方面。尽管 TEPS 被广泛使用，但其因子结构尚未在青少年中进行测试，他们患精神病理学的风险增加，并且正在经历与奖励相关的过程的快速变化。作为回应，本研究旨在测试不同青少年样本中 TEPS 跨时间、性别和种族/民族的因素结构和测量不变性。青少年 ( N = 441; M_年龄= 14.98; 223 名女性）确定为黑人（37%）、西班牙裔（37%）或白人（26%），在基线、6 个月和 12 个月的随访中完成了 TEPS。进行因子分析以检查 TEPS 的因子结构，同时跨时间和人口统计测试配置、度量、标量和严格不变性。研究结果支持 TEPS 的双因素结构，超越其他概念化（例如，4 因素、双因素）、完全纵向不变性和跨性别和种族/民族的部分不变性。对平均差异的检查表明没有时间、性别或种族/民族差异来获得预期的快乐。对于圆满的乐趣，没有发现性别差异，但结果表明随着时间的推移更高水平，而黑人青少年的水平更低。我们的研究结果为通过 TEPS 测量的预期和完成的快感缺失倾向的可靠跨组解释提供了初步支持。总之，结果为 TEPS 在青春期快感缺失相关精神病理学风险评估中的临床效用提供了支持。
