A structured catalogue of psychological tests and scales
The APA PsycTests database access is the go-to register of measurement instruments in psychology, holding thousands of tests and scales in one searchable place. Crucially it carries the metadata that matters — reliability and validity figures, administration norms and scoring rules — so you choose and use an instrument on evidence, not guesswork.
Inside this resource
Thousands of instruments, indexed
From established clinical inventories to research-only questionnaires, the collection catalogues an enormous range of tests and scales, making it the fastest way to find whether a validated measure already exists for a construct.
Psychometrics that the APA PsycTests database access records
Each entry carries reliability and validity information, so you can judge whether an instrument is sound for your population before you commit a study to it — the detail that separates a serious measure from a convenient one.
Administration and scoring in one place
Norms for administration and rules for scoring sit with each test, which means fewer trips to scattered manuals when you are designing a protocol or interpreting a result.
Who this serves
- Researchers designing studies — locate a validated measure and check its psychometrics before fielding it.
- Clinicians selecting assessments — compare instruments on reliability and validity, not familiarity.
- Graduate students — a single reference for the scales a methods or thesis chapter must justify.
Before you buy
Does it include reliability and validity data?

Huge catalogue of instruments. Administration norms in the same place as the test is a real time saver.

Saved me from reinventing a questionnaire — a validated one already existed and this told me its psychometrics.
Dr. Elena R. –
Checked reliability figures on four scales in one sitting before choosing one for my trial. Exactly the metadata I needed.
Dr. Priyanka M. –
Great for justifying measure choice in a methods section. Some niche scales were reference-only but still findable.

Very useful database. I wished a few more full test PDFs were included, but the psychometric detail is what actually matters and it is all there.
