Impulsivity: A Multifaceted Construct

• Impulsivity is a multifaceted construct with varying definitions.
• It can manifest as acting without considering consequences, reacting quickly without conscious judgment, or acting without sufficient thought.
• The International Society for Research on Impulsivity defines it as a behavior without adequate thought, a tendency to act with less forethought, or a predisposition toward rapid, unplanned reactions without regard for negative consequences.
• Impulsivity reflects the tendency to give in to urges, act before thinking, and seek excitement while struggling to control behavior.
