  1. reliability?
    is the measurement tool reliable?
  2. validity?
    is the tool measuring the right thing?
  3. measurement validity?
    is the measurement tool measuring the right thing?
  4. design: internal validity?
    Internal - are the results actually from the IV - validity - are the findings really from the IV.
  5. design: external validity?
    generalize. can we do it?
  6. constant error?
    the same error over and over again.

    • acquiensence - agree/disagree to everything
    • miscalibrated scale
    • fakas that say "yes" or "no" to every question you ask
    • fakas that say the "right thing" to look good. you drink? naw, just once a week...
  7. fuck is a random error?
    errors that vary from one tool to another. 

    heat/cold can affect the way people answer. authority. whether the tester is walking around monitoring or just at their desk.
  8. how does the wording of a question affect the reliability and validity of a tool?
    no one there clarify. person might interpret it differently.
  9. There are 3 methods of testing reliability of a tool:

    stablity,
    equivalence,
    internal consistency. 

    What is stability?
    Same tool, same subj - same results. Test-retest.
  10. There are 3 methods of testing reliability of a tool:

    stablity,
    equivalence,
    internal consistency. 

    what is Equivalence?
    different test give same results OR different researchers give same results. 

    Two tests are based on the same content, but the questions are different.
  11. There are 3 methods of testing reliability of a tool:

    stablity,
    equivalence,
    internal consistency. 

    What is Internal Consistency?
    Make sure all the questions are asking the same thing. 

    Your test about depression shouldn't be asking math questions.

    Split halves (subj half ans compared to their other half) and Chonbach alpha - tests of consistency.
  12. What r-score is acceptable in nursing research?
    0.7
  13. There are three ways to test validity in a tool: self-evident measures (face and content), pragmatic (criteria), construct validity (theory basis). 

    What are Self-evident measures?
    The tool looks like it can do it's job. 

    Face validity - look over it, "seems like it'll do it"

    Content validity - your lit review shows that they are using the same tool. Seems legit.

    Judge panel can look over it.
  14. There are three ways to test validity in a tool:

    self-evident measures (face and content), pragmatic (criteria),
    construct validity (theory basis).

    What is Pragmatic (criteria)?
    Concurrent validity - urine dipstick vs. urinalysis. you know the dipstick works because when you compare the results to the alysis, it's the same.

    Predictive validity -  measure now, and see it it's true. ATI measures ability to pass nclex. You pass ATI? you pass nclex = ATI works.
  15. There are three ways to test validity in a tool:

    self-evident measures (face and content), pragmatic (criteria),
    construct validity (theory basis). 

    What is construct validity?
    Contrasted groups vs known groups - two groups. one good at math, others suck. good at math should score high on math test. sucky ones should score shit = good math test.
  16. when research is conducted in naturalistic or field settings using qualitative data, is the repeatability and reliability of the outcomes easy or hard to achieve?
    hard. lots of variables. field study. qualitative data.
  17. What validity do level III studie use?
    construct.
  18. What do lvl I studies use?
    self-evident/pragmatic
  19. ______ is only for a given population
    reliability
  20. _______ may or may not need to be re-evaluated for a new pop.
    validity
