Development of a standardized measure to predict employee productivity

The London House Employment Productivity Index (EPI-3) is a broad-based personality-oriented measure designed to predict successful employees. This paper focuses on the development and validation of the EPI-3 Dependability, Drug Avoidance, Interpersonal Cooperation, Safety, Validity, and overall Productivity scales. Three validation studies are reviewed. The first is a predictive study using 1,236 subjects from the retail industry. The second predictive study involved 167 subjects from a large discount retail chain. The final concurrent study involved 247 college students employed in various companies. All studies documented the validity of the EPI-3 as a pre-employment selection instrument. This paper also reviews adverse impact research, utility of the instrument for selection and ethical concerns when implementing this type of selection instrument.
