The ambulatory assessment offers a wide range of methods enabling researchers to investigate psychological, behavioral, emotional, and biological processes. These methods enable us to gather data on individual differences in language use for psychological research. Two studies were conducted with an aim to evaluate and compare the temporal stability of language measures extracted by LIWC software form data obtained by two frequently used methods for assessment of language use, i.e., Electronically Activated Recorder (EAR) and stream of consciousness (SOC) task. Additionally, we examined the amount of variance in language use (assessed by both methods) that can be attributed to intra-individual variability and stable individual differences. Study 1 was focused on investigating language use obtained from 74 respondents using the EAR for 3 consecutive days. Study 2 was conducted on 250 respondents participating in a SOC task where verbal production was collected at ten time points over a 2-month period. Results show that measures obtained using the SOC task have higher temporal stability and consistency, and to a certain extent enable better detection of individual differences. Taking into account certain situational variations improves the reliability of EAR measures.
移动评估提供了广泛的方法，使研究人员能够研究心理、行为、情感和生物过程。这些方法使我们能够收集关于语言使用个体差异的心理研究数据。进行了两项研究，旨在评估和比较从两种常用语言使用评估方法（即电子激活记录器 (EAR) 和意识流 (SOC) 任务）获得的数据中提取的 LIWC 软件语言测量的时间稳定性。此外，我们还检查了可以归因于个体内变异性和稳定个体差异的语言使用（通过两种方法评估）的差异量。研究 1 专注于调查使用 EAR 连续 3 天获得的 74 名受访者的语言使用情况。研究 2 在 250 名参与 SOC 任务的受访者中进行，在 2 个月的时间内，在 10 个时间点收集言语产生情况。结果表明，使用 SOC 任务获得的测量具有更高的时间稳定性和一致性，在一定程度上能够更好地检测个体差异。考虑到某些情境变化会提高 EAR 测量的可靠性。
