Mind wandering is a commonly experienced phenomenon. Although self-report measures are available to assess these attentional lapses, examination of their correspondence with the reported frequency of these episodes in daily life is warranted. Using ecological momentary assessments (EMAs), the present study aimed to validate 3 mind-wandering measures: the Mind-Wandering Questionnaire (MWQ) and the Mind Wandering-Spontaneous (MW-S) and Mind Wandering-Deliberate (MW-D) measures in university students (N = 100). Participants completed a series of questionnaires in an in-lab session. Using time-based EMA sampling, participants received 6 prompts via text message daily for 7 days. Each prompt asked students to report if their current thoughts were about something other than what they were doing using a scale ranging from completely on-task to completely on unrelated concerns. Self-report data collected via EMA indicated that reporting more mind-wandering episodes was associated with higher MWQ and MW-S scores but was not significantly correlated with the MW-D score. Results highlight the utility of EMA in validating measures designed to capture mind-wandering episodes. (PsycINFO Database Record (c) 2019 APA, all rights reserved)
