Q. I need psychology articles that include the research, methodology, analysis, data and so on.

It sounds like you need a peer-reviewed (AKA scholarly) article.  These articles are usually research articles that report methodolgy, data, conclusions and more.

For psychology, check out the psychology databases page.  The best databases to start with are:

• PsycInfo
• PsycArticles
• ScienceDirect

When doing your search check to see if there is a check box for Peer-Reviewed articles and check it.
