Validity

Testing Instruments

Clinicians will inevitably review many psychological reports including data resulting from psychological tests throughout their careers. It is imperative that they are well versed on how to evaluate the reliability and validity of psychological tests in order to evaluate the results effectively.

The Mental Measurements Yearbook reviews a multitude of psychological tests and it is a source with which you should become very familiar. For this Discussion, review the psychological test that you were assigned. Use the Mental Measurements Yearbook database in the Walden Library and consider the reliability and validity of the psychological test and the potential challenges to the use of this psychological test in your professional practice.

 

review the following test:

Cattell, R. B., Cattell, K. S., Cattell, H. E. P., Russell, M., & Karol, D. (1994). Sixteen personality factor questionnaire, fifth edition. Champaign, IL: Institute for Personality and Ability Testing, Inc

With these thoughts in mind:

Post by Day 4 a brief description of the psychological test that you were assigned. Then, explain one challenge to reliability and validity in using, interpreting or incorporating this psychological test in your future professional practice.

Describe in words the general pattern of correlation, if any.

Week 5 Practice Worksheet

 

Chapter 13

 

1.   Your research team has been tasked with finding the correlation of the following scenario:

 

Four research participants take a test of manual dexterity (high scores mean better dexterity) and an anxiety test (high scores mean more anxiety). The scores are as follows:

 

Person                          Dexterity                       Anxiety

 

1                                  1                                  10

2                                  1                                    8

3                                  2                                    4

4                                  4                                  -2

 

Describe the process that your research team would go through by completing the following:

 

  1. Make a scatter diagram of the scores. Should be negative direction
  2. Describe in words the general pattern of correlation, if any.
  3. Figure the correlation coefficient.
  4. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing).
  5. Give three logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation in light of the variables involved (and why).

Animals Used for Experimentation

 

  • What is your opinion about using animals for research?
  • Was your opinion affected by the readings for this assignment?
  • Under what circumstances, or for which types of research projects, would you advocate the use of animals in research?
  • Do you think the use of advanced technology, such as fMRI, will eventually make animal testing obsolete?
  • What safeguards do you think would be needed in order to protect participants in studies using neuroimaging methods?

Your response should be at least 2 pages long and should include at least

two scholarly references.
