Into the dynamics of ICD-11 domains: An investigation of their daily endurance and mutual interplay.

The majority of research on dimensional diagnostic models has been conducted using one-time trait measures, constraining the possibility to investigate how their expressions unfold over time. To address that, we recruited 224 participants who filled the daily measures of International Statistical Classification of Diseases and Related Health Problems, 11th ed., states for 30 days (k = 6,132 observations). We found that, after experiencing a preceding increase in the level of any domain, individuals needed more time to return to their personal equilibrium. Next, every significant fluctuation effect regarded negative affectivity, highlighting its role in the process of day-to-day changes between the domains. Taken together, our results suggest the temporal endurance of International Statistical Classification of Diseases and Related Health Problems, 11th ed., domains across daily life, whereas their contemporaneous and spill-over associations suggest that they form an intertwined, dynamic system.
