Copley Library subscribes to the Journal of Nursing Measurement, a peer-reviewed journal publishing "information on instruments, tools, approaches, and procedures developed or utilized for measuring variables in nursing research, practice, and education." (JNM 2024, "About")
Nursing Databases for Measurements, Tests, Scales, Tools, Questionnaires
Searching PubMed for measurements:
MeSH terms - "Surveys and Questionnaires," "Psychological Tests" "Psychometrics" "Evaluation Studies As Topic" "Reproducibility of Results"
MeSH subheading - "Instrumentation" (ex. Nursing/instrumentation, Pain management/instrumentation, psychiatry/instrumentation)
Other terms - scale, survey, measurement, questionnaire, tool, assessment, test
It is always worth a try to email a librarian at the National Library of Medicine to ask for suggestions on accessing a tool or measurement.
