NSSI can be considered a result of risky decision making in response to negative emotions, where individuals choose self-harm over other less harmful alternatives, suggesting a potential decision-making deficit in those engaging in NSSI.

Using computational modeling, we dissected the nuanced cognitive dimensions influencing decision behaviors.
