How to determine personality type

Personality types can be comprehensively judged through professional psychological assessment tools, behavioral observation, self-report, and clinical interviews. The commonly used methods include MBTI personality test, Big Five personality scale, Type 9 personality theory, Rorschach inkblot test, Cattell 16PF personality test, etc.

1. MBTI personality test

MBTI is based on Jung's theory of psychological types and evaluates personality tendencies through four opposing dimensions. The tester needs to answer 93 multiple-choice questions and ultimately determine one of the 16 personality types. This tool is suitable for career planning and team collaboration scenarios, but it should be noted that the type results may vary with the situation. It is recommended to repeat testing every six months to verify stability.

2. The Big Five Personality Inventory

quantifies personality traits from five dimensions: openness, conscientiousness, extroversion, agreeableness, and neuroticism. The Likert five point rating system has high reliability and validity, and can reflect the continuous lineage characteristics of personality. Commonly used in clinical practice to predict job performance and mental health risks, the score distribution needs to be interpreted by trained personnel.

3. The Nine Personality Theory

identifies individuals' core fears and desires through 108 questions, and divides them into nine basic personality types. This system emphasizes defense mechanisms and growth paths, making it suitable for personal development consulting. However, there is a lack of empirical research support, and type determination is easily influenced by the subjective state of testers. It is recommended to combine other tools for cross validation.

4. Rorschach Inkblot Test

Projection Test induces subconscious reactions through 10 symmetrical inkblot images, which are encoded and interpreted by professional analysts. It can capture deep features such as defense styles and emotional organization, but the results depend on the experience of the tester and need to be used in conjunction with standardized scales such as MMPI. Mainly applied in the field of clinical psychology.

5. The Cattell 16PF personality test

measures 16 root traits and 5 secondary factors, including 185 multiple-choice questions. Having cross-cultural norms, it can generate personality profiles for marriage counseling or educational guidance. Attention should be paid to social approval bias during implementation, and if necessary, validity scales should be used to correct the results. When judging personality types, labeling should be avoided, and all assessment results should be dynamically understood in conjunction with individual life history. It is recommended to conduct a series of assessments under the guidance of a professional psychological counselor. Daily observations can focus on individuals' typical response patterns, value rankings, and interpersonal relationship characteristics in stressful situations. Regularly recording behavioral samples and verifying them with evaluation results is necessary to form a relatively accurate personality profile. For clinical diagnostic related needs, standardized validated tools must be used and evaluated with the participation of psychiatrists.
