Diversity Awareness TrainingSanchez & Medkik • Hypothesis • Nature of quasi-experimental design • Measures used & their validity • Tests of Hypotheses • Alternative explanations for results • Learning Points
Hypothesis Diversity Awareness Training Cultural Awareness Differential Treatment of Culturally Different Individuals
Method • Participants • 125 supervisors/mgrs in a county government • 125 Raters of supervisors/mg above • Are no raters evaluating two supervisors?
Method • Design • No random assignment to conditions • Participants in experimental group were chosen bec.. • they were one of 4 employees with the longest tenure in each of their departments & • had not received diversity awareness training • Participants in control group were matched on tenure with those in the experimental group • Control group Ps would have been eligible for training • Did Ps in control group receive training before?
Measures • Pre-training performance ratings • Relevant to training dimensions (e.g., Coworker contact, communication skills) • Extracted for the year immediately before training • 5-point rating scales (# of items not specified) • Anchors used poor to excellent • Issues • Reliability not given
Method • Matched control and experimental groups on tenure • Control variables • Pre-training performance rating • Demographics • Gender, ethnicity, tenure, educational level • Demographics of coworkers who rated Ps in control & experimental groups • Gender & ethnicity
Establishing equivalence • Tested for mean differences between experimental and control group on • Matching and Control variables • Do not present appropriate statistical test results for means but present sds • Present means for categorical variables(!) • Present correlational information

Means on Continuous Control Variables Diversity training is not significantly correlated with any of these variables
Training Outcome Measures • Trainee reactions • 6-items • 5-point Likert rating scales • Reliability=.98 • Completed immediately after training • Only completed by experimental group • Usefulness of mean data
Training Outcome Measures • Cultural Awareness • Correctly pair nine-terms with their meanings • Completed 1 year after training • Previously developed scale called CAI • Reliability=.75
Training Outcome Measures • Differential Treatment Ratings • Coworkers’ ratings of how Ps treated those who were culturally different from Ps • 1 year after training • Previously developed discrimination scale • 10 items rated on 5 point scale • Reliability=.98
Means on Outcome Variables Diversity training is not significantly correlated with any of these variables
Validity of Rater Sample • No differences between participant and rater sample on • Proportions of men & women • Proportions of Whites & VMs • Correlation b/w post-training measures and performance ratings, between supervisor and peer performance ratings • Did raters know whether target was in the experimental vs. control group? • Higher expectations
Preliminary Analyses • Significant correlations between (control) demographic variables • Tenure & Educational level= -.26 • Ethnicity and Educational Level= -.26 • Gender & Ethnicity= -.39 • Coding issues? • 1=male, 0=female • 1=White, 0=VM • 1=less than 5 years, 5=21 years or more tenure • Educational level coding not provided
Preliminary Analyses • Significant correlations between pre-training performance & demographic variables • Coworker Contact & Communication=.50 • Coworker contact & gender=-.24 • Communication & gender=-.22 • Communication & education=.25 • Coding: 1=male, 0=female
Validity of Outcome Variable • Trainee reactions not related to any variable • Usefulness of trainee reactions • Statistical Power issues
Validity of Outcome Variable • Significant correlations with b/w Cultural awareness & control variable • Coworker contact performance =.27 • Criterion validity of outcome variable • Ethnicity=.30 1=White, 0=VM • Education level=.50
Validity of Outcome Variable • Significant correlations between Differential treatment & control variables • Gender=.20 (1=male, 0=female) • Rater ethnicity=.30 (1=White, 0=VM OR 1=VM 0=White) • But no correlation b/w DT & pre-training performance rating • Implications for • Using type of raters • Criterion validity of differential treatment ratings • Do supervisors have opportunity to notice differential treatment?
Hypothesis Testing • Regression analyses to test for mediation effects requires • Independent and dependent variable to be related • Mediator variable to be related to both independent & dependent variables • Criteria not met for… • IV=Training • Mediator=Cultural Awareness • DV=Differential treatment • BUT….forging ahead!
Discussion • Lack of support for hypotheses • Diversity training did not have any effect on social perception biases • Educational level & participant ethnicity predicted cultural awareness • Trainee reactions were positive(!) • Uselessness of these types of measures
Alternative Explanations • Diffusion of treatment among controls • Not supported by higher differential treatment ratings given to trained participants • Selection bias • Lack of differences on control variables including pre-training performance ratings • Trainees held to higher standard by non-white raters
Alternative Explanations • Qualitative analyses of interviews with non-white raters of trainees • Possible backlash due to • Lack of information re: purpose of training • Timing of post-test= need for post-training support • Pre-training beliefs & feelings • Usefulness of non-white raters who interact w/diversity trainee
Learning Points from Article • Writing up unexpected results • Presentation of statistical results • Means vs. frequencies depends on type of variable • Double check statistical results • Discrepancy between correlational and regression tables • Analyses should also be guided by hypotheses
