Edwards Personal Preference Schedule (EPPS): A Brief Overview
The Edwards Personal Preference Schedule (EPPS) is a commonly used psychological assessment tool for measuring individual differences in personality and behavior. Developed by psychologist Jack W. Edwards, the EPPS is a self-report questionnaire that helps clinicians and researchers evaluate personality traits and interpersonal preferences. The EPPS has been widely used in clinical, organizational, educational, and research contexts and has been found to be reliable and valid for making inferences about personality and behavior.
The EPPS consists of 90 items that assess 15 different personality traits. The questions are designed to measure individual preferences and choices in a variety of situations. The items are placed into three categories: Social-Interpersonal, Achievement-Competence, and Power-Dominance. Each category contains five subscales. The Social-Interpersonal subscales measure preferences related to interpersonal relationships, such as friendliness and assertiveness. The Achievement-Competence subscales measure preferences related to academic achievement and self-efficacy. Finally, the Power-Dominance subscales measure preferences related to power and authority.
The EPPS is typically administered in a paper-and-pencil or online format. After completing the questionnaire, individuals are provided with an overall score, as well as scores on each of the subscales. The scores are then used to make inferences about the individual’s personality and behavior. The EPPS has been found to be a reliable and valid assessment tool for making these inferences.
The EPPS is a widely used and well-validated assessment tool for measuring individual differences in personality and behavior. It is particularly useful for making inferences about an individual’s interpersonal preferences, academic achievement, and feelings of power and dominance. The EPPS is an important tool for clinicians and researchers who are interested in exploring and understanding individual differences in personality and behavior.
