The Separation of Adult ADHD Inattention and Hyperactivity-Impulsivity Symptoms and Their Association with...

This study investigates the relationship between attention-deficit/hyperactivity disorder (ADHD) symptoms and problematic short-video use (PSVU) in adults, particularly focusing on the affective and cognitive processes that mediate this relationship. The research aims to clarify how different ADHD symptom domains, specifically inattention (IA) and hyperactivity-impulsivity (HI), contribute to PSVU.

The study recruited 563 Chinese college students (age: mean±SD = 19.85±1.56) through an online survey platform. Participants were assessed for ADHD symptoms, PSVU, cognitive reappraisal, emotional distress (including anxiety and depression), and boredom proneness. Structural equation modeling (SEM) was employed to analyze the mediation effects of these variables on the relationship between adult ADHD symptoms and PSVU. Additionally, the shared and distinct pathway from IA and HI to PSVU in adults were also explored.

The results revealed a serial mediating effect of cognitive reappraisal, emotional distress, and boredom proneness for the association between ADHD and PSVU (Estimate = 0.005, 95% CI = [0.001, 0.014]). Both IA and HI symptoms were found to influence PSVU with increased emotional distress and boredom proneness (IA, Estimate = 0.055, 95% CI = [0.021, 0.099]; HI, Estimate = 0.088, 95% CI = [0.043, 0.150]). However, divergent pathways were found by which IA increased the PSVU indirectly by heightening susceptibility to boredom proneness (Estimate = 0.044, 95% CI = [0.016, 0.086]), whereas HI primarily influenced PSVU through cognitive reappraisal, emotional distress, and boredom proneness (Estimate = 0.009, 95% CI = [0.003, 0.020]).

These findings shed light on how PSVU develops in adults with different ADHD symptoms, which provide valuable insights for developing more targeted prevention and treatment strategies for short-video addiction in ADHD adults.
