Ethnic Validity: Definition and Model Ethnic vah'dity is the degree to which problem identification and problem solving are acceptable to the client in respect to the client's belief and value systems, as these are associated with the client's ethnic~cultural group.1985) and Tyler, Brome, and Williams (1991). While both of these models are instructive and have similarities to the model of ethnic validity proposed earlier, there are important differences in these models and the problem-solving framework of school psychology practice. Savage and Adair.
Internal validity dictates how an experimental design is structured and encompasses all of the steps of the scientific research method. Even if your results are great, sloppy and inconsistent design will compromise your integrity in the eyes of the scientific community. Internal validity and reliability are at the core of any experimental design. External validity is the process of examining the results and questioning whether there are any other possible causal relationships. Control groups and randomization will lessen external validity problems but no method can be completely successful. This is why the statistical proofs of a hypothesis called significant, not absolute truth. Any scientific research design only puts forward a possible cause for the studied effect.
