Recent years have seen an increasing number of studies using smartphones to sample participants' mood states. Moods are usually collected by asking participants for their current mood or for a recollection of their mood states over a specific period of time. The current study investigates the reasons to favour collecting mood through current or daily mood surveys and outlines design recommendations for mood sampling using smartphones based on these findings. These recommendations are also relevant to more general smartphone sampling procedures.
N=64 participants completed a series of surveys at the beginning and end of the study providing information such as gender, personality, or smartphone addiction score. Through a smartphone application, they reported their current mood 3 times and daily mood once per day for 8 weeks. We found that none of the examined intrinsic individual qualities had an effect on matches of current and daily mood reports. However timing played a significant role: the last followed by the first reported current mood of the day were more likely to match the daily mood. Current mood surveys should be preferred for a higher sampling accuracy, while daily mood surveys are more suitable if compliance is more important.
近年来，越来越多的研究使用智能手机对参与者的情绪状态进行采样。情绪通常是通过询问参与者当前的情绪或回忆他们在特定时间段内的情绪状态来收集的。本研究调查了倾向于通过当前或每日情绪调查收集情绪的原因，并根据这些发现概述了使用智能手机进行情绪采样的设计建议。这些建议也适用于更一般的智能手机采样程序。
64名参与者在研究开始和结束时完成了一系列调查，提供了诸如性别、性格或智能手机成瘾得分等信息。他们通过智能手机应用程序，在8周内每天报告一次日常情绪，每天报告三次当前情绪。我们发现，所考察的内在个体特质均未对当前情绪报告与日常情绪报告的匹配产生影响。然而，时间起着重要作用：当天最后报告的当前情绪紧接着第一个报告的当前情绪，更有可能与日常情绪相匹配。如果需要更高的采样准确性，应优先选择当前情绪调查；如果依从性更重要，则每日情绪调查更合适。
