Weighted Application Blank (WAB) Process. Chose criterion Identify criterion groups (e.g., low and high absenteeism) 3) Select items (the more the better) 4) Determine response categories (e.g., true, false; continuum) 5) Determine the weights for each item (e.g., use of regression)

Weighted Application Blank (WAB) Process • Chose criterion • Identify criterion groups (e.g., low and high absenteeism) • 3) Select items (the more the better) • 4) Determine response categories (e.g., true, false; continuum) • 5) Determine the weights for each item (e.g., use of regression) • 6) Estimate amount of shrinkage (e.g., cross-validation) • 7) Evaluate hold-out group scores • 8) Determine cut-off scores
Some WAB Concerns • No single WAB is useful for all jobs • Comparability of sample (generalization) • Change in criterion • Change in nature of job(s) across time • Legal issues (e.g., use of demographic data) • 6) Changes in the organization
Biographical Data (Bio-Data)Process • Choose a specific job • Use of job analysis to select items (use of FJA to cover broader job domains e.g., responsibility, work conditions) and define life history domain (e.g., criterion to use) • Form hypotheses regarding life history background and experience • Construct bio-data items (cover relevant experience domains) • Screen and pilot-test the items • Score bio-data items (single versus multiple scores)
Sample Biographical Information Blank Items • During high school, how many times did you make the honor roll? • How much freedom or independence did your parents allow you in grade school? • How important did your favorite high school teachers stress discipline in the • classroom? • How many times did you change schools before you were sixteen years old? • Compared to other people in high school, how many friends did you have? • How old were you when you spent your first week (or more) away from your • parents? • How bothered are you if you a job is left undone? • How often do you read craft and mechanics magazines? • How quickly do you normally work? • How well do you feel you can understand the feelings of others? • How well do you tolerate performing routine tasks?
Bio-Data [Why does it work?] • Use of life history items e.g., personal background, life experiences, interests (past behavior is best predictor of future behavior) • Only relevant (empirically significant) items are selected • Correlation between BIB content and criterion • Wide range of information (lots of different questions and types)
Bio-Data (cont) • Reliability: .60 to .80 across several studies [higher for more verifiable items] • Validity: Many validity coefficients above .30 • Accuracy: Some distortions exist. Mainly on unverifiable items (e.g., interests, preferences) and more if desirability of answers is apparent (e.g., faking can occur)
Some Bio-Data Issues • Situational specificity • Need large sample to construct properly • Assumption of a “correct” life history • Pure empirical approach (e.g., versus content approach) • Legal issues (e.g. adverse impact, validity, reliability)
