What is a construct, What is a measure, Discuss different levels

What is a construct? What is a measure? Discuss different levels of measures and give examples in your description. Pick a construct and describe that construct in detail. Next, find  two research articles from peer reviewed journals studying that construct. You are to find actual research studies talking about the construct, not review articles for measures.

For example, here is an article ABOUT a measure:  https://link.springer.com/article/10.1007/BF00917219 (This is not the full text of the article)

This is an article that USES measures in a study:  https://jamanetwork.com/journals/jamapsychiatry/article-abstract/494134 (This is not the full text of the article.)

(You want to look for articles that USE measures in a study. Please ask if you don't understand the difference.)

Include the references for those articles and a link to the articles. What specific measures were used in each study? If you were conducting your own study, which one (if either) would you use and why?
