Negative self-scripts refer to the negative thoughts a person has about himself.  It is one of the factors that can make him create a negative self-image about himself.  It also makes him utter negative statements about himself on a daily basis.

Some of the most common causes of negative self-script include:

1. Negative beliefs and negative statements you have about yourself; 

2. Negative descriptions that you receive from peers or members of your own family when you were young, which you hold on to even as you grow up;

3. Negative comments that you incorporate into your belief system;

4. Negative images you have about your body and looks;

5. Negative assessments that others have about your ability and intelligence that you believe is true of you;

6. Negative visualizations you have of your current status or state in life to your personal detriment.

7. Feelings of anger, resentment, hostility or rage you feel toward others for real or imagined mistreatment. This so immobilizes you that your emotional growth gets stunted and you feel negatively about both yourself and life in general.

Negative self-script and a negative self-image can lead a person to lose self-confidence, and it can blow up into depression, social anxiety, difficulty to concentrate, insomnia and other psychological problems. 

Negativism is not a genetic abnormality, but it can affect or influence the lives of people who surround the sufferer, like the members of his family.
