Alcohol and Caffeine Motives in Japanese Nonproblem Drinkers

325 nonproblem alcohol drinkers aged 20-39 in Japan completed surveys on drinking motives, caffeine consumption motives, personality traits, and emotion regulation strategies. The dataset supports analysis of correlations between DMQ-R and MCCQ subscale scores, such as conformity and social motives. It also contains results from a person-centered cluster analysis comparing motive profiles with TIPI and CERQ subscale scores.

Use Cases

• Analyze correlations between DMQ-R subscales (e.g., conformity) and MCCQ subscales (e.g., social) across 325 survey respondents.
• Compare Ten Item Personality Inventory (TIPI) scores like neuroticism and openness between motive-profile clusters derived from DMQ-R and MCCQ data.
• Examine associations between Cognitive Emotion Regulation Questionnaire (CERQ) subscales (e.g., self-blame, rumination) and identified alcohol-caffeine motive clusters.
• Conduct exploratory cluster analysis based on DMQ-R and MCCQ subscale scores to identify combined motive patterns among Japanese drinkers.

Strengths

• Data from 325 survey respondents provides a defined sample for analysis.
• Includes multiple validated psychometric scales: DMQ-R, MCCQ, TIPI, and CERQ.
• Explicitly focuses on the understudied population of nonproblem alcohol drinkers.

Limitations

• The 57.6 KB file size indicates a small dataset with limited scope for complex modeling.
• Sample is restricted to Japanese individuals aged 20-39, limiting generalizability.
• Data is cross-sectional from a single internet survey, preventing causal inference.
