True For an assessment to be considered valid it must be proved to be reliable True Content Relevance, representatives, and technical quality of an assessment instrument Substantive Theoretical rationale Structural Assess whether the internal structure of the assessment instrument is consistent with what is known about the internal structure of the construct domain being assessed. Validity coefficient is a measure of how accurate a measure actually is Reliability and validity are not mutually exclusive concepts rather they are not intimately related. Discriminant validity when scores on a test are found to be uncorrelated to scores on other instruments designed to assess alternate constructs. Ex: Does the SASSI-3 truly detect the presence of a substance abuse disorder? Item analysis homogeneity of a test can be assessed using a number of different procedures Convergent validity scores on a test are compared to scores obtained on other tests believed to measure the same construct. Construct validity test may be said to accurately and thoroughly measure a particular construct or trait. A sound criterion us relevant and useful True A sound criterion should be reliable True A sound criterion is free from bias True A sound criterion measure is immune from contamination True Construct abstraction that cannot be seen directly but is valued because it helps organize the myriad of potential observations in the real world. Predictive validity is the extent to which a score on a scale or test predicts scores on some criterion measure.
