SIGMA's reputation for publishing quality assessments and providing innovative testing solutions is well established. One of our oldest instruments, the Personality Research Form (PRF), is among the most cited measures in personality research. Two new instruments, the Nonverbal Personality Questionnaire (NPQ) and the Five-Factor Nonverbal Personality Questionnaire (FFNPQ), provide psychologists with unique cross-cultural tools.
Efficient and accurate image-based assessment of the 'Big 5' factors of personality.
The JPI-R provides valid and reliable insight into respondents' abilities to function in a wide range of settings including work, organizational, leadership, and social situations.
The LDR is an expert system designed for individuals wishing to improve managerial and executive performance.
The MEIA is a 20-minute measure of EI that captures each of the 10 facets of Salovey and Mayer's (1990) influential EI model.
The NEO-FFI is a shortened version of the NEO PI-R, designed to give quick, reliable and valid measures of the five domains of adult personality.
Based on the Five-Factor model, the NEO PI-R measures the interpersonal, motivational, emotional, and attitudinal styles of adults and adolescents.
The item illustrations in the NPQ make it ideal for cross-cultural applications, and other areas where language may be an issue.
The OSI-R is a concise measure of three (3) domains of occupational adjustment: occupational stress, psychological strain, and coping resources.
