Psychological Testing

  A Practical Approach to Design and Evaluation   For this task, imagine that you were asked to give a scale construction proposal to a group of hypothetical PhD students. The PowerPoint presentation should include the definition of the construct that you intend to make a scale on, the existing tools measuring it, and other related studies. Also include your justification and rationale for your construction. More importantly, discuss how you will construct the items and the item response scales, how you will analyze the items’ reliabilities, and establish the scale’s validity. Incorporate appropriate animations, transitions, and graphics as well as speaker notes for each slide. The speaker notes may be comprised of brief paragraphs or bulleted lists.
