Neurophysiological Indicators of Self-Efficacy in Internet Gaming Disorder

Data Sheet 1 by Hyunho Lee contains neurophysiological and psychological data from a study of 91 participants (46 with Internet Gaming Disorder and 45 healthy controls). The dataset includes late positive potential (LPP) amplitudes from EEG recordings during a cue-reactivity task and questionnaire scores for self-efficacy and interpersonal relationships. The data was last updated on figshare in April 2026.

Use Cases

• Correlate EEG-derived LPP amplitudes with self-efficacy scores based on the Generalized Self-Efficacy Scale mentioned in the description
• Compare neurophysiological responses to game-related cues between IGD and control groups based on the described experimental task
• Investigate the relationship between psychological metrics (self-efficacy, interpersonal relationships) and neurophysiological data in a clinical population
• Analyze topographical patterns of brain activity in centro-parietal and parietal regions in response to specific stimuli

Strengths

• Includes data from 91 participants with detailed group breakdowns (46 IGD, 45 controls)
• Contains multiple data modalities: EEG-derived LPP amplitudes and standardized psychological questionnaire scores
• Data is associated with a peer-reviewed study methodology described in the documentation

Limitations

• Dataset is very small at 37.2 KB, indicating limited scope
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
