Perhaps you should try some spelling variations:
"symbolic interactionism" » "symbolic interactionist", "symbolic interactions", "symbolic interventionism"
"symbolischer interaktionismus" » "symbolische interaktionismus", "symbolischen interaktionismus", "symbolischer interaktions"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("symbolic interactionism") OR ("symbolischer interaktionismus"))) OR ("symbolic integration")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"symbolic interactionism\") OR (\"symbolischer interaktionismus\"))) or (\"symbolic integration\"))".
• Removing quotes may allow a broader search: (((( symbolic interactionism ) OR ( symbolischer interaktionismus ))) or ( symbolic integration )).
• Adding a wildcard symbol may retrieve word variants: (((("symbolic interactionism") OR ("symbolischer interaktionismus"))) or ("symbolic integration"))*.
