<prompt> The parameters of sensitivity and specificity are used for assessing -Criterion validityConstruct validityDiscriminant validityContent validity  <response>: Validity: Refers to what extent the test measures which it purports to measure adequacy of measurementValidity has 2 components: Sensitivity SpecificityTypes of Validity: Conclusion validity: Defines if there is a relationship between 2 variables Internal validity: Assuming relationship between 2 variables, defines if it is causal1. Is free of bias2. Valid conclusions can be drawn for individuals in a sample Construct validity: Assuming causal relationship between 2 variables, defines if our theory is best to our constructs External validity: Assuming causal relationship between 2 variables, defines if our theory can be generalized to the broader population Concurrent validity: Refers to the degree of correlation with other measures of the same construct measured at the same time Face Logical validity: Relevance of a measurement appear obvious Content validity: Measurement of all variable components Consensual validity: If no. of experts agree to a parameterCriterion validity: If compared with a reference or gold standard.1. Is best measure of validity2. Usually expressed as sensitivity specificity Discriminant validity: If not showing strong correlation between 2 variables.
