Abstract
In this article, obsessions and phobic responses are examined in relation to the maintenance and development of a cross-generational coalition organized by a premise about exclusivity, as well as the specific, idiosyncratic "signature premises" characteristic to each case. It is suggested that the obsession develops when a developmental or situational crisis conflicts with the exclusive relationship definition (that is, coalition). Two forms of intervention for disrupting obsessions--the "conversation" and the "counter-obsession"--are discussed and illustrated. Both interventions conceptualize the obsession as an oscillation between remaining in the coalition and not remaining in the coalition, and both interventions challenge the signature premise that defines the coalition.
