Supplementary file 1_Effects of acupuncture and exercise on EEG characteristics and cognitive control in college students with high procrastination tendency.docx

Procrastination is more than just a common human foible; it is a ubiquitous behavioral disorder that can negatively impact learning, productivity, and mental health. The psychological and neurological mechanisms underlying chronic procrastination are surprisingly complex, involving impairments in self-control, emotional regulation, and episode anticipation networks, and may lead to emotional distress, reduced self-confidence, and even physical symptoms that in turn can exacerbate procrastination. The aim of this proposed study is to investigate the clinical efficacy of acupuncture for university students with severe procrastination tendencies, to compare the efficacy of acupuncture to other potential interventions (Tai Chi and running exercise), and to examine the effects of acupuncture on cognitive functions related to procrastination. This parallel randomized controlled clinical trial will be conducted at the Third Affiliated Hospital of Henan University of Chinese Medicine, Henan Province, China. A total of ninety full-time college students will be randomly divided into three equal groups (acupuncture group, running group, and Tai Chi group). Each group will receive the assigned intervention for 30 min per session, 3 times per week on alternating weekdays, for a total of 4 weeks. The General Procrastination Scale (GPS) will serve as the primary outcome measure, while the Procrastination Assessment Scale for Students (PASS) and Physical Activity Rating Scale 3 (PARS-3) will be used as secondary outcome measures. Assessments using these outcome measures will be conducted at baseline (0 week) as well as after 2 and 4 weeks of intervention. Scalp electroencephalography (EEG) will be used to measure event-related potentials P300 and N200 during the Go/No-go Emotion Detection task and Task Initiation Delay Paradigm (TIDP) to investigate the impacts of these interventions on cognitive control and error detection abilities.
