Prospective Assessment of Daily Patterns of Mood-Related Symptoms

Figure 1. Frequency of days reported as having a peak by weekday for each Mood Rhythm Instrument diary (MRI-d) item. The black portion of the bars represents days where a peak was reported, whereas the gray portion represents days where a peak was not reported. For each MRI-d item, y-axis, sum of days from all participants; x-axis, weekday. No difference was detected between weekdays vs. weekends (Chi-square).

Figure 2. Rayleigh plots for each Mood Rhythm Instrument diary (MRI-d) item time variable. Circles represent the 24 h day. Circles along the outermost circumference represent individuals timing: full gray circles represent the median timing of reported peaks on weekdays, whereas open circles represent the median timing of reported peaks on weekends. Fiducial limits are represented.

Figure 3. Agreement rates between the Mood Rhythm Instrument (MRI) and the cumulative mode of the last 3, 5, 7, 11, 13, and 15 days from the Mood Rhythm Instrument diary (MRI-d). Dots show group means. Dichotomous data on each item derived from MRI and MRI-d.

Figure 4. Time differences between the Mood Rhythm Instrument (MRI) and the cumulative median of the last 3, 5, 7, 11, 13, and 15 days from the Mood Rhythm Instrument diary (MRI-d). Dots show group means and whiskers represent 95% confidence intervals. Time data on each item derived from MRI and MRI-d.

Figure 5. Correlation between the number of mood symptoms with a circadian peak (MRI) and current depressive symptoms (BDI scores), (A) and psychological well-being (WHO-5), (B) BDI: Spearman r = 0.44, p < 0.05; WHO-5: Pearson r = −0.55, p < 0.01.
