Integration of marital therapy traditions and evangelical theology is foundational to IMIT. The therapy draws on family, experiential, and cognitive therapy traditions in psychotherapy with groups, individuals, and families.
There are important differences between EFT and IMIT. EFT is rarely applied in an intensive format as is IMIT.
Because of Robert Paul's exposure to working with groups of individuals over several days at a time, and the influence of group marathons in experiential therapy, the group marathon format was a logical choice for developing IMIT. The therapeutic factors of group therapy identified by Yalom (1995) are certainly evident in Couples Intensives conducted at National Institute of Marriage (NIM).
Greendorfer (2004) reports using marathon groups in his work with couples with powerful and "surprisingly long-lasting results." Thus, working with couples in a multi-hour marathon type format is neither new nor unique to IMIT.
IMIT makes some assumptions about self that guide many of the interventions and cognitive restructuring that occurs in IMIT. These assumptions are informed by evangelical Protestant Christian theology as well as psychological research and theory.
This then leads to the second assumption underlying IMIT.
The notion of reactive emotional cycles, or "Fear Cycle," is not unique to IMIT. This dynamic is referenced by EFT proponents as well as other family therapy approaches.
There are a number of therapeutic interventions at the disposal of IMIT. The therapy is less defined by a circumscribed set of interventions than it is by a therapeutic rationale.
It is these therapeutic experiences that are seen as the most critical element of IMIT. Information and articulation of relationship principles is secondary to facilitating therapeutic experiences.
Davis and Piercy (2007a, 2007b) have examined common factors in three different approaches to couples therapy that share similarities with IMIT. It is not surprising that their research on "model dependent" and "model independent" factors in couples therapy confirms many of the theoretical conceptualizations and interventions used in IMIT.
To take the last first: in 35 there occurs the term [Greek Words Omitted]; it seems to denote the notion of accessible, but is not normally used in contexts relating to style.(45) Our compiler, however, in offering his highly condensed remarks about Thucydides, admiration of Homer and Pindar, seems to have incorporated terminology of his own, in this instance he may have been glossing Dionysius' [Greek Words Omitted] in De Imit.
