Development of the Hogan Personality Content Single-Items Inventory

Area of Science:

• Psychological assessment
• Organizational psychology
• Personality research

Background:

• Hogan Personality Inventory (HPI) and Hogan Developmental Survey (HDS) are validated for organizational use but underutilized in basic research.
• A need exists for efficient personality assessment tools in research settings.

Purpose of the Study:

• Introduce the Hogan Personality Content Single-Items (HPCS) inventory.
• Evaluate the reliability and validity of HPCS for measuring HPI and HDS content subscales.
• Explore the utility of single-item scales in personality assessment.

Main Methods:

• Developed HPCS with one item per HPI/HDS content subscale (74 items total).
• Assessed reliability (retest, self-other, other-other agreement).
• Examined convergent validity with full HPI/HDS scales and criterion-related validity.

Main Results:

• HPCS demonstrated adequate item-level retest reliability.
• Both self-other and other-other agreement were satisfactory.
• HPCS showed convergent correlations with corresponding full HPI/HDS scales.
• HPCS and full HPI/HDS related similarly to other variables.

Conclusions:

• HPCS is a reliable and valid instrument for measuring HPI and HDS content subscales.
• HPCS offers a time-efficient alternative to full inventories in certain research contexts.
• Findings inform best practices for developing and using single-item scales.
