: For this project, you will be critiquing the following original empirical research article that reports the results of testing validity and reliability of a research instrument in a special population.
Iacono, T., West, D., Bloomberg, K., & Johnson, H. (2009).
Reliability and validity of the revised Triple C: Checklist of Communicative Competencies
for adults with severe and multiple disabilities. Journal of Intellectual Disability Research, 53(1), 44-53.
In addition to explaining the study design and results, use the information from the textbook as well as the article to explain each type of validity and reliability that was evaluated in the study. Be sure to answer the following questions in your critique:
a. Do you have confidence in the research design (e.g., the number of participants, the inclusion criteria, the methods)? Why or why not?
b. Do you have confidence in the researchers analyses of the validity and reliability of the instrument? Why or why not?
c. Would you have confidence in the instrument based on the validity and reliability of the instrument as demonstrated in the study? Why or why not?
d. Would you have any reservations using the instrument in future research? Why or why not?
e. What additional types of validity and reliability, if any, would you want to determine in future research that were not tested in this study?
f. Discuss the purpose of demonstrating validity and reliability in the population sampled in the study. Can these results generalize to other populations (ages, gender, abilities) or cultures?
