About Measures
A guide to understanding what a psychological measure observes and which interpretations its scores can support.
Start with the question
Browse 22 selected questionnaires, performance tasks, informant reports, test batteries and structured observations. Search by name, construct or developer; filter by topic and format. A profile separates procedure, scoring logic, development, reliability, validity, use, limitations and access.
The reading guide explains how to evaluate a measure. Score examples work through synthetic data without collecting anyone’s health answers. The textbook map connects exact sections of OpenStax Psychology 2e.
Scope and evidence
This is a selected introduction, not a complete test catalog or a ranking. Common use is not proof of universal validity. Each profile identifies whether evidence comes from primary research, developer guidance, a publisher or textbook context, including abstract-only access.
The site does not administer clinical instruments, diagnose visitors, reproduce protected tests or supply a professional scoring service. Reading about a measure is different from being trained or authorized to use it.
