Q. I need information on the relationship between personality and parental confidence as well as the relationship between marital status and personality
I recommend you start with our library Psychology Research guide. The first database listed on this page is PsychArticles. First, I tried the search terms:
"Marital Status" AND Personality
When you are on the results page, look under the SUBJECT heading on the left hand side of the page. You can browse some of the subject headings to get ideas for additional searching.
For the topic Parental Confidence and Personality, you might try searching
Parenting AND Personality
When I did this search, there was a SUBJECT heading for Parental Characteristics. I think would be helpful for narrowing your search to parental confidence.
The Psychology Research guide also has a tab for Book/eBooks, and Reference Sources. We have several electronic books that may have information for you on this topic.
