One of 10 tables from the same source; this one measures Big Five Personality Test -Emotional Stability. The others are listed under Related tables.

About this table

Description	The personality test was constructed with the "Big-Five Factor Markers" from the IPIP. https://ipip.ori.org/newBigFive5broadKey.htm IPIP-FFM-data-8Nov2018.zip

Classification

age range	Adult (18+)

construct type	Personality
measurement tool	Survey/questionnaire
item format	Likert Scale/selected response
primary language(s)	eng
construct name	Big Five Personality Test -Emotional Stability

These are classifications the IRW records, not the study’s own words. Some were annotated by hand and some written by an automated tagger whose output is published only where it clears a measured accuracy bar; which values came from which is not recorded per table. Coverage and accuracy per column, and what is held back, are on Tag quality.

This table is in 2 collections. Each membership records how it was decided:

Big Five / FFM big_five — by rule
Response time response_time — by rule

Membership is the IRW’s judgment and is worth checking before you use a collection as a sample. A hand-curated list is a snapshot: it is not re-checked when tables are added, so a table that would qualify may be missing. See Collections.

Item text

This table has item text in the IRW: the wording administered to respondents, not just the response codes.

Codebook

This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, ffm.R. It is our best reading, not the source’s own codebook, and it may contain mistakes. Where the two disagree, the source data are the authority. If you find an error, please tell us.

Column	What it is	Source column
IRW standard columns
`id`	IRW standard Identifier for the focal unit being measured — typically a person, but sometimes another entity (e.g., a word in a lexical task).	made in the build script
`item`	IRW standard Item identifier.	made in the build script
`resp`	IRW standard Response value.	made in the build script
`rt`	IRW standard Response time.	made in the build script

What item codes and covariate values stand for is in the codebook released with the source data.
