## About

# Criterion-related validation

Evidence that **scores on a selection procedure are statistically related to one or more measures
of work-relevant behavior or outcomes**. The strongest form of "does it predict?" evidence — but
also the most demanding on sample size, criterion quality, and analysis.

## Feasibility first

Three things determine whether a criterion-related study is even sensible:
1. **A relevant, reliable, uncontaminated criterion** is available or buildable. **Relevance is the
   most important** property.
2. **A representative research sample** of the workforce/candidate pool exists.
3. **Adequate statistical power** is attainable. Estimate the needed sample size *before* the study
   from the expected effect size, the statistic, and the chosen alpha. Range restriction and
   criterion unreliability inflate the corrected coefficient but **also inflate its standard error**
   — so distinguish observed from corrected coefficients when judging power. Underpowered studies
   are a chronic failure mode; give Type II error equal attention to Type I.

If any of these is badly deficient, a criterion-related strategy may not be feasible — consider
`content-based-validation` or `generalizing-validity-evidence`.

## Design: predictive vs. concurrent

- **Predictive** — predictor collected at/around selection; criterion collected later (after a
  retention interval or once performance stabilizes).
- **Concurrent** — predictor and criterion collected on incumbents at about the same time.

For **stable cognitive abilities**, predictive and concurrent estimates tend to be comparable. For
**noncognitive self-reports** (personality, interests, SJTs) and **experience-based measures**
(biodata), the designs can diverge — e.g., applicant **faking** motivation differs from incumbents';
biodata responses may reflect on-the-job experience. So results don't automatically generalize
across designs or predictor types. Match the design's inference to your use.

Other design choices that matter: the basis on which sample members were selected, the population
sampled (applicants vs. recent hires vs. fully experienced), and whether you're predicting
**higher-level** work (acceptable if a substantial share advance and you use criteria at both the
hire level and the higher level).

## Criterion development

Choose criteria for **relevance, freedom from contamination, and reliability** — *not* availability
or convenience. Criteria should represent important organizational, team, or individual outcomes.

- **Relevance** — reflects standing on an outcome critical to success (job performance, training
  success, turnover, OCBs, advancement). Need not be all-inclusive, but the link to the proposed
  use must be clear and rationale documented.
- **Contamination** — systematic variance *unrelated* to the construct (machinery quality, sales
  territory, rater knowledge of predictor scores, shift, location, rater attitudes). Minimize via
  standardized administration; measure and statistically control contaminants where possible.
- **Deficiency** — excludes relevant variance (a "performance" criterion missing behaviors critical
  to performance). If the criterion can't cover the full domain, **state what is omitted** and the
  implication for the inference.
- **Criterion bias** — systematic error from contamination/deficiency that *differentially* affects
  subgroups. Cannot be detected from criterion scores alone; anticipate and guard against it with
  professional judgment.
- **Reliability** — identify the conditions of measurement (raters, items, occasions) you want to
  generalize across and design to estimate the matching reliability. Internal-consistency estimates
  may be inadequate for ratings (they ignore rater and time variance).

Common criterion types: **supervisory performance ratings** (most common; ratings collected *for
research* are preferable to administrative ratings — Jawahar & Williams, 1997), other performance
indices, **archival/HRIS data** (verify accuracy, alignment, consistency, and data-privacy
compliance before use).

## Choice of predictor

- Predictors need a **theoretical, logical, or empirical** foundation; specify the rationale before
  the study. Verify serendipitous findings (especially from small samples) by independent
  replication.
- Base preliminary choices on the **work analysis** and scientific knowledge, not personal
  familiarity or bias.
- Keep the **construct vs. method** distinction explicit (e.g., "the interview" is a method, not a
  construct) to avoid uninterpretable comparisons.
- Address **predictor contamination** (unstandardized administration, irrelevant content, cheating,
  faking — unstructured interviews and unproctored internet tests are higher risk) and **predictor
  reliability** (estimate it for the conditions of intended use).
- When **algorithms** score structured/unstructured inputs (text, resumes, stimuli responses),
  document the conceptual/methodological basis, provide **cross-validation** evidence, and ensure the
  algorithm does not introduce systematic bias against subgroups.

## Choice of participants

- The validation sample should **represent the situation you'll generalize to** (demographics,
  motivation, ability, experience). Convenience samples are discouraged to the extent they're
  unrepresentative.
- You generally **cannot** validate separately for every subgroup. Only test for bias when there is
  credible evidence of potential bias *and* sufficient data (adequate power and precision) for the
  proper analysis — see `fairness-and-bias-analysis`. A subgroup too small to analyze cannot be
  compared until more data exist.

## Data analysis

- Ensure analyses fit the data (level of measurement, sample size, non-independence/clustering).
  Don't pick a method because the software is handy; if you delegate analysis, you retain
  responsibility for its suitability and accuracy.
- Report **effect sizes, statistical significance, and standard errors / confidence intervals** for
  predictor–criterion relationships; describe distributions (central tendency, variance) and
  interrelationships.

### Adjustments (corrections) to validity estimates
- Aim for an **unbiased estimate of operational validity**. Observed coefficients misestimate the
  population value because of **range restriction** and **criterion unreliability**; apply suitable
  bivariate/multivariate corrections when an appropriate estimate is available.
- **Do not** correct for **predictor** unreliability for operational use (you use the actual,
  unreliable predictor).
- For ratings criteria, internal-consistency reliability may be inadequate — account for rater and
  time variance.
- Corrected coefficients are point estimates: usual significance tests/SEs for *unadjusted*
  coefficients don't apply. **Report both corrected and uncorrected** values, and use procedures
  built for corrected coefficients when testing significance / forming CIs. State explicitly when a
  coefficient is theoretical and not the operational validity.

### Combining predictors and criteria
- Document the **method of combination**: multiple regression, Pareto-optimal weights, unit weights,
  rational weights, etc. Effective weights ≠ nominal weights (they depend on variances/covariances),
  especially when predictors are **differentially range-restricted**.
- **Compensatory vs. noncompensatory** combination (and cutoffs/sequencing) affects rank order,
  expected mean criterion standing, and subgroup differences — see
  `selection-decisions-and-scoring`.
- **Cross-validate** composites built from regression (or any data-driven weighting/keying) to guard
  against capitalization on chance, especially in small samples. Unit/rational weights don't shrink.

## Interpreting results

Interpret against the cumulative research literature. **Unusual findings** (suppressors, moderators,
nonlinearity, configural scoring, differential weighting of highly correlated predictors) are
suspect — require a very large sample or replication before acting on them.

## Pitfalls

- Choosing an available criterion over a relevant one.
- Ignoring power until after data collection.
- Reporting only corrected validities, or applying naive significance tests to them.
- Correcting for predictor unreliability and treating it as operational validity.
- Capitalizing on chance via regression/empirical keying without cross-validation.
- Generalizing concurrent results to a predictive (applicant) use for fakable measures.
