Bland–Altman plots assessing agreement between the CNBQ and EMA food diaries for selected variables. CNBQ, Chrono-Nutrition Behavior Questionnaire; EMA, ecological momentary assessment; SD, standard deviation. All time-related variables are shown in decimal format, with the unit of clock time; decimal (e.g., 8.50 means 8:30 AM, while 16.75 means 4:45 PM) or hours; decimal (e.g., 2.19 means 2 h 11 min). Eating midpoint 2 was calculated using the start time of first eating occasion and the finish time of last eating occasion. n = 1050 except for eating jetlag based on breakfast timing (n = 753). The number of days of EMA food diary data was 2–9 (median 7) days for (a), (c), and (e); 2–9 (median 4) days for (b), (d), and (f); and 11 days for (g).
