Objective The nonsuicidal self‐injury (NSSI) disorder diagnostic criteria have been the focus of empirical study. However, Criterion A (i.e., required frequency and timeframe) has received relatively limited attention. The current study aimed to examine the relationship between past 12‐month NSSI frequency and eight NSSI behavior features among individuals with past 12‐month and 1‐month NSSI. Method Participants were 723 undergraduate students reporting at least 1 past 12‐month NSSI act and completed online questionnaires. Decision trees and structural equation model trees were utilized to examine the relationship between NSSI frequency and behavior features. Results Results highlight several potential subgroups: high (i.e., greater than 49 acts), moderate‐to‐high (i.e., 19–48 acts), low‐to‐moderate (i.e., 7–18 acts), and low (i.e., fewer than 6 acts) frequency subgroups. Conclusions Findings suggest that increasing the NSSI disorder criterion A frequency cutoff or requiring at least one past month NSSI act may better demarcate individuals with more severe NSSI behavior.
