Using CV and NL in searches

In the Medline Database, I was looking to find sources for the following prompt:

How are people using the Internet for self-help or support group work on psychological problems (like depression) or social problems with psychological components (like domestic violence or gambling addiction)? I need scholarly articles based on solid research, not descriptions of bulletin boards or forums.

I began by thinking of controlled vocabulary and natural language terms that fit the reference question. I started by using words in my natural language to begin to look for appropriate sources. I made a list of terms including the phrases "online therapy" and "e-therapy." When searching for this terms, I discovered some suggestions for controlled vocabulary as well, including the terms "Internet," "remote consultation," "mental disorders" and "psychology."

From there, I used various combinations of terms, and found that the most productive searches were ones that included the "AND" Boolean expression, and connected a CV and NL term. I got the most successful hits when searching for "online therapy" (one of my natural language terms) and "remote consultation" (one of the controlled vocabulary terms I discovered). This use of both CV and NL is a logical way to best search for information because it covers both bases.
