生态瞬时评估是一种现在主要用于研究自然发生环境下的行为和情绪的方法。它最大限度地提高了生态有效性并避免了回顾性自我报告的局限性。缺乏对通过手机生态瞬时评估进行量表的心理测量特性的研究。所以。我们收集了衡量健康状况的 4 项情绪量表的数据，每天对 7 种粘土进行 6 次油（N = 307），并检查了不同时间、一天内和一周内的依从率。使用特定的潜在状态-特质结构方程模型，我们分析了所有测量场合中个体间情绪差异由于（a）测量误差而产生的程度。 (b) 情绪水平的稳定差异，以及 (c) 特定场合的差异。结果显示良好的合规性（平均合规性：74.9% 的电话得到应答）。此外，该量表显示出良好的信度（M = .82）。情绪大多稳定，尤其是一周的前三天。它对先前的评估（自回归系数）有微弱但显着的依赖。总之，计算机化手机评估是一种合适、易于使用且有前途的情绪测量方法。
Ecological momentary assessment is a method that is now largely used to study behavior and mood ill the settings in which they naturally occur. It maximizes ecological validity and avoids the limitations of retrospective self-reports. Studies on the psychometric properties of scales administered via mobile phone ecological momentary assessment are lacking. Therefore. we collected data oil a 4-item mood scale measuring well being, oil six occasions per day for 7 clays (N = 307) and examined compliance rate across time, within day, and within week. Using specific latent state-trait structural equation Models, We analyzed the degree to which interindividual mood differences Oil all occasion Of measurement Were because Of (a) measurement error. (b,) stable differences in mood level, and (c) occasion-specific differences. Results show good compliance (mean compliance: 74.9% of calls answered). Moreover, the scale showed good reliability (M = .82). Mood was mostly stable, especially the first 3 days of the week. It depended weakly albeit significantly on the previous assessment (autoregressive coefficient), In conclusion, computerized mobile phone assessment is an appropriate, easy-to-use, and promising method to measure mood.
