German:
Wann sollte welche Validierungsmethode (Augenscheinvalidität, Kriteriumsvalidität, Konstruktvalidität,...) eingesetzt werden?"
English:
"Using bad measuring instruments can have disastrous consequences. Therefore newly developed tests, questionaires, etc. have to meet the highest standards. Along with reliability and objectivity validity is one of the most important quality criteria. An instrument is regarded as valid, if it measures, what it is supposed to measure. For example: A (supposed) intelligence test which measures creativity or sustained attention may be reliable, but it is not valid.In this episode we will discuss the different methods to validate a measuring instrument:
- face validtiy
- criterion validity
- predictive
- postdictive
- construct validity
- discriminant construct validity
- concurrent construct validity"
