SocIndex and ProQuest Social Science carry more social science journals than just sociology!
Read abstracts closely to be sure the author is taking a sociological approach to the topic. If you are working in the sub-field of social psychology, you can use social psych sources, but stay away from psychology journals.
How would an abstract read if it is sociology? It can mention a social theory, equality, marginalization, society, social groups....
Sometimes it is very clear from the title of the journal; sometimes it is not.
What are the author's credentials? Is he/she a criminologist, sociologist, ethnologist? Sometimes this info is on the first page of the article. You might have to "Google" the author to find out.
