Non-Suicidal Self-Injury Survey of Korean Undergraduates

Aggregating 188 self-reported questionnaire responses from a web-based survey of Korean undergraduate students conducted in August-September 2020. It examines predictors of non-suicidal self-injury (NSSI), including psychological discomfort and cognitive emotion regulation strategies, with 30.3% of participants reporting NSSI in the past six months.

Use Cases

• Analyze the association between psychological discomfort scores and reported NSSI incidents.
• Examine the moderating effect of positive cognitive emotion regulation strategies on the relationship between psychological discomfort and NSSI.
• Compare NSSI prevalence and associated factors between female and male participants within the 188-person sample.
• Model predictors of NSSI using demographic variables and cognitive emotion regulation strategy scores.

Strengths

• Data from 188 participants provides a specific sample size for analysis.
• Includes a clear temporal context: data collected in August-September 2020 during the COVID-19 pandemic.
• Specific prevalence figure: 30.3% of participants reported NSSI within the past six months.

Limitations

• Small sample size of 188 limits statistical power and generalizability.
• Sample is geographically limited to South Korea and predominantly female (159 of 188 participants), introducing demographic bias.
• Data is cross-sectional from a single time point, preventing causal or longitudinal analysis.
