Finding appropriate materials or measures (see Chapter 5 on qualities of measures) is among the biggest challenges for researchers. The first step is identifying what measures might be appropriate. As was true for identifying seminal articles, keep track of the scales and measures used repeatedly in a given area. For example, if you are interested in the topic of self-esteem, you will repeatedly see citations to Morris Rosenberg’s Self-Esteem Scale (1965). This scale has a high internal consistency (in the neighborhood of .88), which means the items relate to each other (i.e., are measuring the same concept). In addition, there are only 10 items, which is a consideration in terms of the number of items you may ask respondents to complete.
