Document Summary

Observed score = true score + systematic error + random error. Make sure observed closely corresponds with true score. Constructs of disinterest motivation, test-wise, test anxiety, english proficiency. Validity extent to which an instrument represents constructs, without contamination from other systematically varying constructs. Face define construct with a concept. Content measures represent all content areas. Muscle dysmorphia: pharmacological use, supplement use, dietary behaviour, drive for body size, physique protection, exercise dependence. Criterion (can be at same time as validation or in future) Concurrent validity: at the same time as validation, simultaneous measure and criterion. Predictive validity: correlates with prediction in future, measure then criterion. Known group: showing it differentiates between two different groups based on assumption one group should score higher or lower. Convergent: correlation between different measures of same construct.
