Instrument Reviews

Assessing the Instruments Reliability and Validity

You should assess an instrument's validity and reliability before you try to obtain its full text.

Where you find that data depends on whether the instrument is "published" or "unpublished." 


Published Instruments
Published means commercially published, and that the instrument is typically available for sale. You can find reviews of many published instruments, including validity and reliability data, in Mental Measurements Yearbook with Tests in Print Database.
Example:
The MMPI-2 (Minnesota Multiphasic Personality Inventory) is a published instrument.
 
Unpublished Instruments
Unpublished means that the instrument has not been commercially published. You can find reviews of unpublished instruments in many of the Resources for Identifying Instruments. If you are not sure where to start, try APA PsycTests or HaPI.
Example:
The LANSS (Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale) is an unpublished instrument.
