IS_MEMBER returns the following values.

IS_MEMBER determines Windows group membership by examining an access token that is created by Windows. The access token does not reflect changes in group membership that are made after a user connects to an instance of SQL Server. Windows group membership cannot be queried by a SQL Server login or a SQL Server application role.

The following example checks whether the current user is a member of a database role or a Windows domain group.

-- Test membership in db_owner and print appropriate message.
IF IS_MEMBER ('db_owner') = 1
   PRINT 'Current user is a member of the db_owner role'
ELSE IF IS_MEMBER ('db_owner') = 0
   PRINT 'Current user is NOT a member of the db_owner role'
ELSE IF IS_MEMBER ('db_owner') IS NULL
   PRINT 'ERROR: Invalid group / role specified'
GO

-- Execute SELECT if user is a member of ADVWORKS\Shipping.
IF IS_MEMBER ('ADVWORKS\Shipping') = 1
   SELECT 'User ' + USER + ' is a member of ADVWORKS\Shipping.' 
GO
