Scale Construction

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.
Support your presentation with at least five scholarly resources. In addition to these specified resources, other appropriate scholarly resources may be included.
the construct of interest is,the study by Ito et al. (2015) successfully examined marijuana abuse within the framework of the theory of planned behavior. It is a dominant model which explains health behavior and determines whether components of the TPB theory have associated with both the intention to engage in a behavior and behavioral engagements as such. The general area of interest were young college students and their responses to marijuana legalization in the United States. Specifically, the TPB revealed that the predictor variables concerning the psychosocial influence of the constructs of initial attitudes, norms, and efficacy were related to the outcomes reported, resisting use on initial intentions and examined the effects of the original plans on the use of marijuana.
