For this Integration Assignment, you will develop a structured measure of personality, collect data on the measure, and examine its psychometric properties. You will use one of the deductive approaches to structured test construction (either the logical-content or theoretical strategies) described in Chapter 13 of your text. Before you begin this assignment, be sure to review information on writing and evaluating items in Chapter 6.

These examples may or may not have all the necessary components, as such they are simply provided to give you an idea of how to approach this project. When completing your own project, be sure to review the grading rubric and the directions below. You are responsible for ensuring that you have met all the relevant guidelines.
Conceptualizing the Personality Scale
- Select a personality construct, trait, or characteristic your scale will attempt to measure.
- Carefully review all material (e.g., book chapters, journal articles, etc.) on the personality construct, trait, or characteristic of interest. Your task will be to write a set of items that reflects the construct domain, so try to identify as many aspects or dimensions of the construct as you can. (Note: This is a fundamental step in the scale construction process and is necessary to provide evidence of the validity of your scale.)
- Consider how you will test the reliability and validity of your scale after you have constructed it. For example, you might want to provide construct-related evidence for the validity of your scale. How might you do this?
- Identify the item format you will use (e.g., dichotomous, Likert scale, checklist, etc.). You must use the same format for all items on the scale.
Developing the Personality Scale and Associated Materials
- Write 10 items you believe measure the construct of interest. Be sure to review the guidelines for writing items presented in Chapter 6 of your text. Also, review the Grading Rubric that will be used to evaluate the items you have written. (Note: The majority of your items should be face valid, but you might want to consider incorporating some filler items and/or items that assess response styles.)
- Write a set of demographic items (e.g., gender, age) to accompany your scale.
- Write a set of directions for examinees. These directions will appear at the top of the scale you developed.
- Write a set of instructions for scoring your scale. Be sure to identify items that are reverse-scored. Also, specify what a high or low score on the scale indicates (e.g., greater or lesser degrees of the trait).
Evaluating the Personality Scale
- Administer your scale and additional measures to 5 examinees. Make sure your examinees do not write their names or any other identifying information on the scale.
- Analyze the scale data, including:
The median, mean and standard deviation of scores
Additional analyses using demographic variables
- Write an APA-style report describing the development and evaluation of your personality scale. The report should contain the following sections:
Introduction (including a description of the construct and the purpose of the study)
Method (including descriptions of participants, an appendix of measures, and procedure used to construct and test the scale)
Results (including a description of specific analyses performed and results)
Discussion (including an evaluation of the properties of the scale you created, how you would revise or improve your scale, and recommendations for further study of the scale)
References (include a minimum of three references)
