The fourteen personality factors questionnaire (CPQ) was compiled by Dr. Porter of Indiana State University and Professor Carter of the Institute of Personality and Testing of Illinois State University. The test content includes fourteen aspects: gregarious, intelligent, stable, excited, bullying, relaxed, persistent, aggressive, sensitive, rich, sophisticated, anxious, self-disciplined and nervous. Fourteen personality factors are independent, and each factor has little correlation with other factors. Therefore, the measurement of each factor can make the subjects have a clear and unique understanding of the personality characteristics of the subjects and a comprehensive understanding of the combination of 14 different factors of the subjects' personality, so as to comprehensively evaluate the children's personality.

The explanation of each factor is generally as follows:

Factor a-gregarious: describe whether you are willing to associate with others and whether you are enthusiastic about others;

Factor b- intelligence: describe the abstract thinking ability and the intelligence of the testee;

Factor c- stability: describe the ability to withstand setbacks and whether it can achieve emotional stability;

Factor D- Excitement: Describe the degree and intensity of emotional excitement.

Factor e- domination: describe whether you are willing to dominate and influence others and whether you are willing to lead others;

F factor-liveliness: describes the positive and happy degree of emotions;

Factor G-Responsibility: Describe the acceptance and conscious implementation of social moral norms and standards;

Factor H- aggressiveness: describe boldness in social situations;

Factor 1-sensitivity: describe the degree of sensitivity, that is, whether judgment and decision are easily influenced by emotions;

Factor J- richness: describes the level of energy and initiative of the subjects.

Factor n- sophistication: describe whether you can handle things skillfully and flexibly;

Factor O-anxiety: describes the degree of anxiety and depression experienced;

Factor Q3- Self-discipline: Describe the degree of self-discipline and self-motivation;

Factor Q4- Tension: Describe the degree of instability in life and heart, and the related tension.

In addition to directly measuring these 14 personality characteristics, Professor Carter and others have also developed a series of formulas. Using the scores of the previous 14 scale and these formulas, we can also calculate some minor personality characteristics, mainly including:

1. Adaptation and anxiety: describe the degree of adaptation to the current environment and whether you feel anxious or dissatisfied;

2. Introversion and extroversion: describe the degree of introversion or extroversion of personality characteristics;

3. Are you nervous? Describe whether it is easy to have a neurotic reaction to external things.

CPQ has been translated into many languages and is a widely used personality test in the world. Researchers in China also modified the test to make it more suitable for the national conditions in China. After testing, the test has good reliability and validity. This test can measure 14 main personality characteristics in about 40 minutes, which is suitable for primary and secondary school students aged 8- 14. It is recognized as a better child personality test scale.
