Use it as a subquery and join to it:

select * from 
(
    SELECT  ParticipantId 
    FROM Contact
    WHERE (IsCurrent = 0 AND IsActive = 1 AND ContactTypeId = 1)
    Group by ParticipantId
    Having COUNT(ParticipantId) > 1
) base
inner join Contact c on c.ParticipantId = base.ParticipantID
WHERE (IsCurrent = 0 AND IsActive = 1 AND ContactTypeId = 1)
