Problem 2 - Selection Flashcards
Personnel selection procedure
- process: job analysis - competency model - person specification
Job analysis: job-oriented procedure
- focus on the work itself (the task)
- description in terms of the equipment used, the end product, resources and materials
Job analysis: worker-oriented procedures
- description of the psychological and behavioral requirements of the job
- communication, decision making and reasoning, knowledge, skills, and abilities
Task performance vs contextual performance
- task performance - specific responsbilities
- contextual performance - organizational citizenship behaviors
Content validity
- extent to which the test is representative of the actual construct
- face validity: the extent to which a test is perceived as measuring what it is supposed to measure.
- user acceptability: how fair and relevant users find it for the job.
Construct validity: convergent/discriminant
- the relation between a test score and the construct you intend to measure.
- convergent validity: degree to which the measure is related to other measures of similar constructs.
- discriminant validity: degree to which the measure is unrelated to measures of distinct constructs.
Criterions validity: concurrent/predictive
- extent to whcih a measure is related to an outcome.
- concurrent validity: predictor and criterion are measured at the same point in time.
- predictive validity: predictor measured at time 1, criterion measured at time 2.
- incremental validity: how much accuracy is added by adding more predictors
- data collection - predictive follow-up design or concurrent design (existing employees)
Reliability and validity
- reliability is the boundary condition for validity
- reliability is an unsystematic measurement errors
- validity is a systematic measurement errors
Reliability
- the consistency or repeatability of the measures.
- the extent to which a measurement tool gives consistent results over time.
Test-retest reliability
- correlation between two scores on the same test at two measurement points (Repeatability)
Internal reliability
- the consistency of results across different items in a time (internal consistency or Cronbach’s alpha)
Inter-rater reliability
- the degree of agreement between two or more raters (ICCs, Cohen’s kappa)
Validity
- the extent to which the observed test score is a good indicator of the construct you intended to measure/predict.
Selection methods: interviews
- Panel = more than one
- structure/unstructured or semi structured
- high validity = interviewers are trained
structured:
- best - consistent across every interviewer
- questions are based on the job
- criterions related validity
behavioral interviewing - description of previous behaviors related to the job.
- predicts job performance, validity etc.
Situational interviews - goal-seeting theory, hypothetical job-related situations with questions
- not very reliable, is validity to some extent, predicts to some extent.
Selection methods: psychometric/personality tests
- tests of cognitive abilities/personality
- can indicate either maximal (cognitive abilities) or typical performance (personality)
- extraversion + consciousness = biggest predictors
- cognitive abilities predict job performance for complex job
