A summary of a new instrument that has been developed by the author(s) of the journal article listed in the Source field.

The citation (listed in the Source field) is the publication by the original authors, where the instrument was first described and introduced in the literature.

Use this Source Code (or Source Note) as a filter when you need the foundational paper detailing how the test was created, along with its initial psychometric testing and validity data.

A summary of an existing instrument that has been re-administered to participants in a later study.

In some cases, the author(s) of the Source article developed the instrument, but reported its development in an earlier publication. In other cases, the authors are merely using an instrument developed by earlier researchers.

Use this Source Code if you’re looking for additional reliability or validity data, as well as applicability of the instrument to other ages or other settings.
