Self-control is the ability to regulate one’s emotions, thoughts, and behavior in the face of temptations and impulses. Common goals such as exercising regularly, eating a balanced diet, being more productive, giving up bad habits, and saving money are just a few worthwhile ambitions that usually require self-control to achieve. Self-control is important for maintaining healthy behaviors. The Self-Control Scale measures an individual's ability to control their impulses, alter their thoughts and emotions and prevent undesired behavioural tendencies to prevent acting upon them.
