Scale Categories

All of the scales reviewed in the database are placed into at least one of these major categories. As an alternative to doing a keyword search, you can click on these category names and see what scales are related to them. Keep in mind that some of the categories have dozens of scale reviews while other categories contain hundreds.

Search the Scales Library

If you are looking for psychological measures to use in a questionnaire, this is where you can search the world's largest repository of multi-item scales that top social scientists have used in their surveys and experiments.  You can use the same measures as the experts!  Each of the full reviews has information about a scale's psychometric quality, who has used it, and the questions/statements that compose the measure.  For an idea of what a full review looks like, see this sample.

How to Find & Purchase Scale Reviews

Option #1: Day Pass 

The best way to find measures that fit your research needs is to enter the Scales Library where you can see the full reviews of all scales in the database.  It is also the best deal for most researchers because it allows you to do all of the searching, reading, comparing, and downloading of scales you want in a 24-hour period for only $39.  (Read more about the Day Pass.)

Option #2: A la Carte

If you just want a scale or two and you are sure which of the thousands of scales is best based on the limited descriptions provided for free then this option may make the most sense.  In that case, scale reviews are $9 a piece.  To begin, start your search by using any of the methods described below. 

  • One way to search is by typing 1-3 words in the search box above. The search terms may be the name of a construct (e.g., loyalty), a key part of a scale’s description (e.g., Internet), or an author’s name (e.g., Smith). 
  • An alternative way to find a scale of interest is to click on a category (to the left) and skim through the scales associated with it.  Each scale in the database is associated with at least one of these major categories.
  • The third way to search for scales is to look through the dozens of key words that have been used to code the scales.  The list is shown at the bottom part of the site map.  Each scale has been coded with between four and six key words.  When you click on a key word you will be shown a list of the scales that have been associated with it.

When you find a scale for which you want to download the full review document, click the Add to cart button under its brief description.  After selecting all the reviews you want, click the Shopping Cart at the top right corner of the page to continue the purchase process.  After paying for your order, click on the Purchased Reviews tab on My Account page and from there you can download the document(s) you ordered.
