Subclinical Psychiatric Symptomatology and a Proposed Diagnostic Criterion Separating Psychopathological Procrastinators From Trait Procrastinators.

Abstract

Procrastination trait describes irrational delays of scheduled tasks despite clear awareness of the adverse consequences of doing so. Although procrastination is well-known to be linked to psychiatric or pathological processes, the criterion for "psychopathological procrastination" distinguishing from the procrastination trait is understudied. This is a 5-year longitudinal observational study. Participants (N = 464) completed measures of trait procrastination in 2018, with a follow-up conducted in 2023 (N = 267) collecting subclinical symptomatology. A constrained multivariate direct gradient model (cmDGM) was employed to prospectively predict subclinical psychiatric symptomatology formulated by the DSM-5 framework. The two-stage psychopathological connectome model was then constructed to constitute a "diagnostic criterion" reflecting "psychopathological procrastination." Procrastination prospectively predicted subclinical psychopathological symptoms and unhealthy lifestyles. Subclinical bridge hubs of "failure to self-regulate delays," "failure to control adverse consequences," "useless to self-change," "out-of-control irruptions," "poor sleep quality," and "negative emotional reactions" were identified in the two-stage psychopathological network. These hubs constituted the 9-item pathological procrastination diagnostic criterion (3PDC) with good diagnostic performance (AUC = 0.82, p < 0.01). The present study revealed the predictive role of procrastination for subclinical psychiatric symptomatology and further established the subclinical 3PDC to lay the foundation for the "diagnostics of psychopathological procrastinators."
