Week 4 Summative Assessment: Test Development: Psychological…

Assignment Instructions Psychometrics is a broad term used to define the theory behind the use and practice of psychological assessments. Psychological assessments comprise the measurement of psychological constructs and how that information is used in a clinical setting to help formulate the clinical case and make treatment decisions. Psychometrics is also used in a forensic setting to answer questions about a person involved in the legal system, such as criminal prosecution or for a civil matter (e.g., custody dispute). Data from psychological assessments is also used to improve efficiency and overall functioning in an organizational setting. Construct Development and Test Creation Paper Throughout Weeks 3 and 4, we explored the properties of psychometric assessments. For this assignment, you will apply those principles to develop your own test to measure a psychological construct. Imagine you are working as a research assistant and have been asked to develop a measurement construct to solve a problem or collect data. Choose a construct you would like to measure (depression, anxiety, etc.). Create an operational definition of your construct using at least 3 peer-reviewed journal articles as references (you can use the DSM as a scholarly source to define your construct, but please do not use websites). Create a 10-question test to measure the construct. Write a 1,250- to 1,400-word analysis in which you: Justify whether this is an interview or self-report instrument and the method of scaling you used to create the test items. Describe the methods you used for item selection and how item selection was evaluated. Describe how you would norm this instrument. For your description, you should: Discuss how many people you would give it to. Describe the characteristics that your respondents would have (gender, age, SES, etc.). Explain to whom the instrument would be generalized. Describe how you would establish reliability. Describe how you would establish validity. Submit your assignment.
