v Social Desirability Ratings – A repository for item ratings from Psychological inventories via Allen Edwards’ item rating method.



v Item Response Theory (IRT) is often referred to as the “modern” psychometric (measurement of psychological constructs) theory, being contrasted most commonly with Classical Test Theory (CTT) [aka. True Score Theory] and Generalizability Theory approaches and procedures. Applied to testing situations, IRT models provide interpretive frameworks for assessing the relationships between item endorsement and underlying ability.


v The Society for Industrial and Organizational Psychology (SIOP) is an Organizational Affiliate of the American Psychological Society, and Division 14 of the American Psychological Association. SIOP is the professional membership organization for I/O Psychologists, and a good resource for individuals interested in the field of I/O Psychology. At their website, you will be able to access more information about the kinds of functions that someone with formal training in I/O Psychology might typically perform. In addition to SIOP, there are several regional organizations that deal with issues of psychology and work. Some of these regional interest groups include:

Ø  Chicago Industrial/Organizational Psychologists (CIOP)
