API Adult Personality Inventory

API (Adult Personality Inventory) was developed by Samuel E. Krug (1984). It assesses major dimensions of adult personality, career preferences, personality differences, and interpersonal styles.

The assessment also includes three measures of cognitive ability. API results are reported in terms of three sets of scales: Personal Characteristics, Interpersonal Style, and Career Factors.

The third set of scales, Career Factors (Practical, Scientific, Aesthetic, Social, Competitive, Structured), relate to career choice, job satisfaction, and life-style preferences.

The following personality dimensions are measured:

• Extroversion
• Discipline
• Adjustment
• Creativity
• Toughness
• Entrepreneurship.

The scales were developed empirically by studying response patterns that differentiated people in a broad sampling of occupations.
