Average depression, severity scores aggregated each month. Results As participants’ increased severity, similarly. Over half participants reported clinically significant ISI (59.38%). In both random intercept slope models, there (F=20.69; p<0.0001) (F=87.44, p<0.0001). While boundary statistical (F=3.54; p=0.0618), dropping 15.17 (April) 12.58 (December), our longitudinal analyses revealed no difference effect or predicting time. Participants’ monthly averages varied sleep (ISI) 16.07 (SD=3.76 6.34 December September, respectively), 3.47 6.39 (SD=3.36 5.26 June, (PHQ-8) 4.47 6.10 (SD=4.65 4.39 respectively).
