QC-ATTENTION

Attention & Instructed-Response Checks

Data Quality

Items that detect inattentive or careless responding. Insert one or two into a longer battery — not more, and not in every beep of an ESM protocol, where they irritate participants and become their own source of dropout.

SQ-Brief

Brief Sleep Quality Assessment

Sleep

A 4-item momentary sleep quality battery covering quality, duration, latency, and daytime restoration. Suitable for daily diary and EMA protocols.

DEMO-CORE

Core Demographics

Demographics

The minimal demographic set most studies report: age, sex, gender, country and language. Age and date of birth are both included — pick whichever your ethics approval allows, you rarely want both.

DEMO-DEVICE

Device & Technology Use

Device & Technology

Phone platform, wearable ownership, screen time and notification habits. Worth collecting in any smartphone study — notification responsiveness and platform are the two variables most likely to explain compliance differences between participants.

EMA-Core

EMA Core Battery

EMA / Context

A standard momentary assessment battery covering mood valence, arousal, stress, social context, and current activity.

EXIT-DEBRIEF

Exit & Debriefing Survey

Study Methods

Closing battery for the end of a study: overall experience, technical problems, self-reported data quality and willingness to be re-contacted. The technical-problems item is the fastest way to find out that notifications silently failed for a subset of your sample.

CTX-FULL

Extended Momentary Context Battery

EMA / Context

A fuller context battery than EMA-Core: physical location, social company, activity and its pleasantness, plus consumption and phone use since the previous beep. Designed to be subset — most protocols use three or four of these, not all ten.

OECD-FUTGEN

Harmony with the Needs of Future Generations (OECD experimental)

Wellbeing

How often a person feels in harmony with the needs of future generations, 0–10. A sense of connection to ancestors and descendants features in many Indigenous well-being frameworks (for example the Māori notion of being a good ancestor), and several OECD countries have legislation on the well-being of future generations. Few measures exist; the OECD offers this item in an experimental question bank.

DEMO-HEALTH

Health Background

Background & History

Self-reported health history: general health, chronic conditions, medication, anthropometrics and smoking. Health data is special-category under GDPR Art. 9 — every item here is flagged accordingly and needs an explicit lawful basis, not consent-by-default.

DEMO-HH

Household & Relationships

Demographics

Relationship status, household composition and living situation — the background variables most often used to contextualise social ESM data.

OECD-FAMILY

How Your Family Is Doing (OECD experimental)

Social

An evaluation of how well one's family is doing, 0–10, with a follow-up on which groups of people the person counted as family. Developed for Te Kupenga, Statistics New Zealand's survey of Māori well-being (where it asked about whānau), and used in the New Zealand General Social Survey. Highly correlated with life satisfaction but distinct in its drivers. One of the OECD's experimental measures: the OECD asks data producers to field and publish tests of them.

DEMO-MIG-EU

Migration Background (European Union)

DemographicsEuropean Union

The standard European alternative to a race/ethnicity question. Most EU ethics committees discourage collecting racial or ethnic origin directly, and official European statistics instead derive migration background from country of birth of the respondent and their parents. Note that migration background can function as a proxy for ethnic origin — treat the derived variable with Art. 9 caution even though the individual items are not themselves special-category data.

DEMO-MIG-DE

Migrationshintergrund (Germany)

DemographicsGermany

The German official definition of migration background: a person has a Migrationshintergrund if they, or at least one parent, were not born with German citizenship. Items carry German translations — switch the language selector to Deutsch before inserting to get the German wording.

MSIQ

Momentary Social Interaction Quality

Social

A 5-item EMA battery assessing the quality of current or most recent social interactions, covering presence, pleasantness, understanding, conflict, and social connection.

5 items

OECD-CONTEXT

Moment Context: Activity, Place and Company (HETUS-based)

EMA / Context

Where the person is (including how they are travelling), what they are mainly doing, who they are with, and whether they are interacting with anyone. Options map to HETUS 2018 codes, so answers can be compared with official time-use statistics. Pair with the OECD time-use pleasantness item or momentary affect.

OECD-CORE

OECD Core Well-being Questions: Life Satisfaction and Worthwhile

Wellbeing

The OECD's primary measure of subjective well-being (life satisfaction) and its eudaimonic measure (the things one does in life are worthwhile), each on a 0–10 scale. About 60 seconds. Best asked at baseline and exit, early in the survey and not straight after questions on income, health or other sensitive topics. Asked word for word, the answers are comparable with national statistics: close to 90% of OECD countries collect the life-satisfaction item. The OECD core module has a third item on pain over the past 7 days, which is not included in this entry.

OECD-DOMAIN

OECD Domain Satisfaction: Free Time, Local Environment and Job

Wellbeing

Satisfaction with the amount of time for things one likes doing, with the quality of the local environment, and with one's job, each on a 0–10 scale. These are items 8–10 of the OECD's ten-item domain evaluation module; its items 1–7 come from the Personal Wellbeing Index and are not included in this entry. Ask the job item only of respondents who are employed.

OECD-EUD

OECD Eudaimonia: Worthwhile and Autonomy

Wellbeing

Two of the five constructs in the OECD eudaimonia module: a sense that the things one does are worthwhile, and autonomy (being able to do the things one really wants and values). Both on 0–10 scales. The module's items on accomplishment, self-esteem and personal growth are not included in this entry. The worthwhile item is also an OECD core item; ask it only once.

OECD-LE

OECD Life Evaluation Module: Now, a Year Ago and Hope

Wellbeing

Life satisfaction now and one year ago, and hope for the future, each on a 0–10 scale. About 60 seconds. The first item is the OECD core life-satisfaction item; ask it only once if the survey also uses the core questions. If space is short, keep the one-year-ago item over the hope item.

OECD-TU

OECD Time-Use Pleasantness

EMA / Context

The OECD's recommended affect question for time-use diaries: how pleasant or unpleasant a moment was, from −3 to +3. Designed to be answered for each diary episode, as soon after it as possible; in an experience-sampling study it can be asked about the moment of each prompt, alongside where the person is, what they are doing and who they are with.

BURDEN-EMA

Participant Burden & Reactivity

Study Methods

Measures how heavy the protocol felt and whether taking part changed what was being measured. Reactivity is the standard threat to validity in ESM and is almost never measured — these items make it reportable. Pairs with the Burden Centre's observed-compliance estimates.

PA-1

Physical Activity – Single Item

Physical Health

A brief momentary and retrospective physical activity assessment battery for EMA use, covering recent activity level, type, and perceived exertion.

DEMO-ETH-US

Race & Ethnicity (United States)

DemographicsUnited States

US federal standard for race and ethnicity, following the 2024 revision of OMB Statistical Policy Directive No. 15. The 2024 revision replaced the old two-question format with a single combined question and added 'Middle Eastern or North African' as a distinct category — do not use the superseded 1997 wording.

QC-EFFORT

Response Effort & Data Quality Self-Report

Data Quality

Asks participants directly about the quality of their own answers. Surprisingly effective and much less irritating than attention checks — participants are largely honest when told their answer will not affect payment. Place at the end of a session.

SRMH

Self-rated Mental Health

Wellbeing

A single general self-assessment of mental health, from excellent to poor. Part of the OECD's population mental health module.

DEMO-SES

Socioeconomic Position

Demographics

Education, employment, occupation and income position. Education follows ISCED 2011 and occupation follows ISCO-08 major groups, so results map onto official statistics rather than ad-hoc categories. Income is asked relative to the country average to avoid currency and cost-of-living problems.

DEMO-DISAB

Washington Group Short Set on Functioning

Background & History

The six-item UN standard for identifying disability in surveys. Asks about functional difficulty in six core domains rather than asking respondents to self-identify as disabled, which is why it works cross-culturally.
