  1. What type of directness of measurement involves concrete things like oxygen saturation, VS, weight?
    direct measures
  2. What type of directness of measurement involves abstract concepts like pain, depression, coping, etc.?
    indirect measures
  3. What is the term for the difference between the true measure and what is actually measured?
    measurement error
  4. What type of measurement error happens when the difference is without pattern?
    (e.g. sometimes scores are high, sometimes low, don't get same answer each time)
    random error
  5. What type of measurement error happens when the variation in measurement is in the same direction? Consistent error occurs when the measurement approach does not represent the true score (e.g. uncalibrated scale)
    systematic error
  6. What is the lowest of the four levels of measurement, includes mutually exclusive, named, and exhaustive categories? Gender, ethnic background, race
    nominal-scale measurement
  7. What level of measurement involves order/ranking imposed on categories, numbers preserve order, and have unequal intervals?
    Army ranks (1-enlisted personnel, 2-noncommissioned officer, etc.)
    ordinal-scale measurement
  8. What level of measurement includes numerical distances between intervals that are equal and the absence of a zero point? Temperature
    interval-scale measurement
  9. What level of measurement is the highest level of measurement and is a continuum of values with an absolute zero point? Weight, age, length, volume
    ratio-scale measurement
  10. What is the term for what is concerned with how consistently the measurement technique measures the concept of interest and is concerned with the amount of random error?
    reliability
  11. What are the three types of reliability?
    • equivalence
    • stability
    • consistency
  12. What type of reliability is the consistency of performance among different raters in assigning scores to the same objects or behaviors in the same measurement situation, using the same tool and/or the same predefined criteria?
    equivalence reliability
  13. What includes two or more raters with the same patient?
    interrater reliability
  14. What includes two or more forms with the same patient?
    parallel forms
  15. What is the term for the consistency of measurements that one instrument or tool elicits from one group of subjects on two separate measurement occasions? Stability of the test
    test-retest
  16. What is the term for the consistency with which one rater assigns scores to a set of behaviors on two occasions? Stability of the rater
    intrarater reliability
  17. What is the term for if the items are related to each other and if they're measuring the same thing?
    homogeneity
  18. What does homogeneity test?
    internal consistency reliability
  19. What determines homogeneity?
    Cronbach's alpha coefficient
  20. What is the term for the extent to which an instrument or measurement approach measures the actual parameter of interest of the true score? Concerned with the amount of systematic error
    validity
  21. What type of validity is the extent to which the content of a scale is representative of the conceptual domain it is intended to measure?
    content
  22. What type of validity is when a new method of analysis is compared to a gold standard?
    criterion
  23. What type of validity is the extent that the measure relates to other measures of similar concepts?
    construct validity
  24. What type of observational measurements involves recording what is seen and is less objective?
    unstructured observations
  25. What type of observational measurements uses category systems, checklists, and rating scales?
    structured observations
  26. What is the term for what is most commonly used to describe opinions or attitudes and describes degree of agreement, evaluation, and frequency?
    Likert Scale
  27. What type of measurement scale consists of questions with two opposing adjectives with 7-point scale and is used to measure attitudes or beliefs?
    semantic differential scales
  28. What type of measurement scale is a 100 mm line and the participant marks rating point on the line?
    visual analog scales
  29. What type of measurement scale involves rating something on a scale from 0-10?
    numeric rating scales
