6. PsycINFO – Subject search
Hands-on buttons training (2)
Why consider employing thesaurus terms?
• Capture
acronyms, homonyms, hyponyms and synonyms
Mind you: NOT hypernyms! (why?)
• Retrieve records containing
- relevant terms you didn’t search for
- topic(s) not otherwise covered in the record

7. PsycINFO – Subject search
Maximizing relevance (‘precision’)
Assignment 2.1
Search for one answer to the following background question :
How does the Child PTSD Symptom Scale perform regarding
diagnostic accuracy (in- and exclusion of PTSD in children of
max. 18 y. old)?
Maximize relevance by applying any (combination of) options below:
• Rephrasing your question
• Adding (additional) limits
• Adding PICO elements to your search
• Using narrower terms
• Restricting to specific search fields

8. PsycINFO – Subject search
Maximizing the number of relevant records (‘sensitivity’)
Maximize the number of retrieved relevant records:
• Extracting synonyms from relevant full records by screening
abstract (.ab) and title (.ti)
• Searching all fields (.mp)
• Omitting elements from your PICO
• Using broader terms
• Avoiding the use of limits

9. PsycINFO – Subject search
Maximizing the number of relevant records (‘sensitivity’)
[Optional expert level]
• Analyse “Related Terms” and “Used For” in the APA thesaurus
• Extract key concepts (.id) and classification codes (.cc) from
relevant records by screening
• If applicable: search .tm field

10. PsycINFO – Subject search
Finding evidence
Clinical queries:

(study filters)
- http://www.apa.org/pubs/databases/training/method-values.aspx
(methodology field values)

11. PsycINFO – Translate search to other database(s) (2)
Failures trying to re-execute your search without adjustment,
due to:
• Other fieldcodes for the same field
i.e.: journal word = .jx (Embase), .jw (PsycINFO)
• Unique fieldcodes per database
i.e.: .id in PsycINFO
• Multifieldcodes search different fields
i.e.: .mp, .tw
• Differences in thesauri

12. PsycINFO – Translate search other database(s) (3)
More on differences between thesauri
Example: functional resonance imaging / fmri
Medline
magnetic resonance imaging [MeSH]
Embase [Emtree]
BT: nuclear magnetic resonance imaging
functional magnetic resonance imaging
PsycINFO [APA thesaurus]
BT: magnetic resonance imaging
functional magnetic resonance imaging
Be aware of dismbiguation between terminology systems
Example: neuropsychology
