Decreased Specific Pavlovian-to-Instrumental Transfer Effect in Internet Gaming Disorder following Short-Term...

Area of Science:

• Neuroscience
• Psychology
• Behavioral Science

Background:

• Internet Gaming Disorder (IGD) is associated with enhanced game-related specific Pavlovian-to-instrumental transfer (SPIT).
• The malleability of this SPIT effect in IGD remains largely unexplored.

Purpose of the Study:

• To investigate whether short-term gaming abstinence influences the game-related SPIT effect in young adults with IGD.
• To assess the potential reversibility of incentive sensitization in IGD.

Main Methods:

• Sixty young adults with IGD were divided into an abstinence group (7-day cessation) and a control group (maintained gaming).
• Game-related SPIT and social-reward general PIT (GPIT) were measured before and after the intervention period.
• Statistical analyses, including linear mixed models, were used to evaluate changes in SPIT and GPIT effects.

Main Results:

• The abstinence group showed a significant decrease in game-related SPIT from baseline to follow-up, unlike the control group.
• A significant reduction in IGD severity scores was observed in the abstinence group compared to controls.
• The reduction in SPIT magnitude positively correlated with decreased IGD symptom severity within the abstinence group.

Conclusions:

• Brief gaming abstinence can attenuate game-related SPIT in individuals with IGD.
• Findings suggest a reversible incentive sensitization mechanism in IGD, highlighting the clinical potential of abstinence-based interventions.
