The Daily Cognitive Communicative and Sleep Profile (DCCASP) is a seven-item instrument that captures daily subjective sleep quality, perceived mood, cognitive, and communication functions. The objective of this study was to evaluate the reliability and validity of the DCCASP. The DCCASP was self-administered daily to a convenience sample of young adults (n = 54) for two two-week blocks, interspersed with a two-week rest period. Afterwards, participants completed the Pittsburgh Sleep Quality Index (PSQI). Internal consistency and criterion validity were calculated by Cronbach's α coefficient, Concordance Correlation Coefficient (CCC), and Spearman rank (rs) correlation coefficient, respectively. Results indicated high internal consistency (Cronbach-s α = 0.864-0.938) among mean ratings of sleep quality on the DCCASP. There were significant correlations between mean ratings of sleep quality and all domains (rs=0.38-0.55, p<0.0001). Criterion validity was established between mean sleep quality ratings on the DCCASP and PSQI (rs=0.40, p<0.001). The DCCASP is a reliable and valid self-report instrument to monitor daily sleep quality and perceived mood, cognitive, and communication functions over time, amongst a normative sample of young adults. Further studies on its psychometric properties are necessary to clarify its utility in a clinical population.
每日认知、交流与睡眠概况量表（DCCASP）是一种包含七个条目的工具，用于获取每日主观睡眠质量、感知情绪、认知及交流功能。本研究的目的是评估DCCASP的信效度。在两个为期两周的时间段内，对一个由年轻成年人组成的便利样本（n = 54）每日进行DCCASP的自我施测，中间穿插一个为期两周的休息期。之后，参与者完成匹兹堡睡眠质量指数（PSQI）。分别通过克朗巴哈α系数、一致性相关系数（CCC）和斯皮尔曼等级相关系数（rs）计算内部一致性和效标效度。结果表明，DCCASP上睡眠质量平均评分之间具有较高的内部一致性（克朗巴哈α = 0.864 - 0.938）。睡眠质量平均评分与所有领域之间均存在显著相关性（rs = 0.38 - 0.55，p < 0.0001）。DCCASP上的睡眠质量平均评分与PSQI之间建立了效标效度（rs = 0.40，p < 0.001）。DCCASP是一种可靠且有效的自我报告工具，可用于在一段时间内监测年轻成年人标准样本的每日睡眠质量以及感知情绪、认知和交流功能。有必要对其心理测量特性进行进一步研究，以阐明其在临床人群中的效用。
