Objective. To examine the relationship between the extraversion/introversion personality dimension and mildly injurious (fingernail biting, skin picking, etc.) and more injurious (cutting, burning, etc.) self-harming behaviors.
Method. An undergraduate sample of 146 students volunteered to complete several measures including the Eysenck Personality Questionnaire-Revised and Self-Harm Information Form.
Results. Participants with no history of self-harm endorsed similar levels of extraversion in comparison to participants with a history of mildly or moderately injurious self-harm. Comparison between the groups using a One-Factor Between Subjects Analysis of Variance was not significant.
Conclusion. A proposition is made to expand future research examining self-harm and extraversion/introversion by exploring what function the self-harming behavior serves and focusing on a clinical population in order to further explore any possible relationship between these variables.
