Integrity screening
A structured measurement of reliability and integrity risk in employees or candidates, typically based on a nominal-scale questionnaire complemented by response-time analysis and consistency checks.
Glossary — terms around integrity screening
Eleven common terms around integrity screening, psychometrics, and GDPR. Neutral, science-based definitions.
Social desirability
The tendency of respondents to give socially acceptable rather than truthful answers. Verity measures social desirability in a dedicated domain (ID 5) — a high score is a reliability indicator on the report.
Cross-comparison
Repeating questions in alternative phrasings to detect inconsistent answer patterns. Used in Verity as an independent reliability check alongside response-time analysis and social desirability.
Response-time analysis
Analysis of the time a respondent takes to answer each question. Unusually fast answers may indicate guessing or prior knowledge; unusually slow answers may signal external assistance or overthinking.
Nominal scale
A measurement scale where answers fall into categories without inherent ranking — yes/no, true/false, or multiple choice with equivalent options. Verity uses nominal scales for integrity measurement.
Cronbach's alpha
A statistical measure of the internal consistency of a questionnaire — assesses whether items within one domain measure the same construct. Values ≥ 0.7 are considered acceptable in psychometric research.
K-anonymity
Privacy threshold that prevents individuals from being identifiable in group reports. Verity applies k=5 by default — a group must contain at least 5 respondents before aggregated scores are shown.
GDPR / AVG
EU Regulation 2016/679 for data protection. Relevant for screening platforms: lawful basis for processing (Art. 6), special category data (Art. 9), storage limitation (Art. 5(1)(e)), right to be forgotten (Art. 17), and the required data processing agreement.
Psychometrics
The scientific field concerned with the construction and validation of psychological tests. Key concepts: reliability (test-retest, internal consistency), validity (construct, criterion, content) and norm data.
Norm group
The comparison population against which individual scores are percentile-ranked. A score on an instrument is only meaningful relative to a relevant norm group — for example 'Dutch healthcare workers' versus 'global workforce'.
Manipulation detection
The combined mechanisms for recognising strategic answering behaviour — i.e. respondents trying to influence the report rather than answer truthfully. Combines cross-comparison, response-time analysis, and social-desirability scores into a single reliability judgement per candidate.
