Schwartz’s Portrait Values Questionnaire (PVQ-RR) [114] is a widely used and
translated measure of human values. We only use PVQ-RR subscales related to
conscientiousness: Achievement (ACHV), Conformity (CONF), and Security (SCRT).
Criterion Validity Metrics: We consider relatively stronger correlations between
IPIP-NEO domain subscales with their respective related external measures, compared
to correlations with unrelated measures, as evidence of criterion validity. For example,
we would expect IPIP-NEO Extraversion to be more strongly correlated with a known
external criterion, such as PANAS Positive Affect, relative to an unrelated external
phenomenon, such social conformity values (e.g., measured by the PVQ-RR’s Confor-
mity subscale). Since external criteria are known to relate to personality at varying
strength levels, we interpret criterion validity on a trait-by-trait basis and refrain from
setting hard cutoffs.
