Out of 3 self-report measures of PA (ie, EMA, GPAQ, and BAR) were completed according to the following timeline: EMA was completed on 1 weekday and 1 weekend day; GPAQ was completed on the first day before participants were provided with the waist sensor; BAR was completed daily between days 1 and 6 (Figure 1).
Design of a 7-day study. BAR: Bouchard’s physical activity record; EMA: ecological momentary assessment, GPAQ: global physical activity questionnaire.

The relevance and validity of EMA data rely on the comparability with traditional methods of measurement (eg, surveys) and the overall adherence to the EMA protocol among participants. This study provides insight by directly comparing smoking-related measures collected through EMA and surveys. The nonsignificant paired difference found in this study contrasts with other similar studies that found large discrepancies between retrospective and EMA data [25,26].

Data for the proximal effects of the MRT was acquired via ecological momentary assessment (EMA). That is when an eligible moment of NA or smoking was detected from sensor data, that moment was randomized to either deliver a mindfulness or motivational strategy or not. Motivational messages were included due to high desirability in previous m Health cessation studies [34-36].

Newer technology (eg, continuous glucose monitoring [CGM] and ecological momentary assessment [EMA]) provides a unique opportunity to explore the specific glucose patterns that influence dynamic cognition; that is, cognitive functions that fluctuate in the short-term and are easily influenced by environmental factors [12,13]. Using these approaches in adults with T1 D, a few studies have shown an association between short-term glycemic control and cognitive functioning.

Ecological momentary assessment (EMA) is a methodological approach to capture people’s moods [20,21] and behaviors in their natural environments [22-26]. Recently, EMA has expanded beyond self-report data to include smartphone sensor data [27]. This is known as passive EMA, which describes EMA systems where sensor-based data are collected without any user interaction [26-28].

Participants were randomly assigned to either (1) an “EMA as usual” (EMA Group) protocol, in which they participated in a 21-day EMA study with 4 survey prompts per day, or (2) an “EMA + DD” (EMA+DD Group) protocol, in which they participated in the same study design but also received a personalized message with a DD once per day.

Advances in smartphone technology have allowed researchers to couple brief cognitive testing with frequently repeated ecological momentary assessment (EMA), opening the door to studying cognitive performance as it occurs in the natural environment [1].

Both groups participated in a 21-day EMA study that included 4 survey prompts per day (up to 84 prompts total). Participants were randomized to either participate in a traditional EMA study, where standard text prompts with links to a survey were received 4 times per day (EMA group), or an augmented study condition in which the text prompt was accompanied by a DD for 1 randomly selected survey per day throughout the EMA protocol (EMA+DD group).
