Your assignment is to develop a self-report measure designed to assess the personality construct of conscientiousness and an accompanying report.
Your measure should be made up of 10 self-report items that measure individuals’ levels of conscientiousness in the context of an Applied Tests and Measures class. Specifically, your items should target how conscientious a person is in the context of this class. Your items should be in a continuous (Likert) scale format. Follow the item writing guidelines presented in the Self-Report Measure Construction lecture (see the link below). Be sure to include appropriate instructions. Include these components in the appendix of your report.
For this assignment, imagine that you were contracted to develop a conscientiousness measure for Tests and Measures Testing Corporation to assess students’ conscientiousness in future Tests and Measures courses. Write a three paragraph report in APA (6th edition) format that addresses the three bullets below:
Define and describe conscientiousness
Discuss what method of estimating reliability you would recommend for this assessment and why. In your response, identify what would be considered an acceptable reliability coefficient.
Discuss at least two types of validity evidence you would seek to obtain. In your response, define each type of validity evidence and explain the process for identifying that evidence.
