· Validity Types: Does it really capture the concept? Construct validity, face validity, predictive validity, convergent validity, discriminant validity, content validity

· Generalizability: the degree to which the measure is applicable across conditions, situations, or even populations

· Methods for construction: theoretical approach – base measures on theoretical descriptors of the construct, rational approach – based on commonbase understandings of the construct, empirical approach – based entirely on statistical procedures

· Factor Analysis: used to evaluate a measure or construct a measure; it’s a correlational, widely-used statistical procedure in personality research to reduce a large number of variables (items) into clusters of variables (factors); a factor is an underlying common theme responsible for items clustering together – it gives them meaning but involves subjectivity
