DECK stands for Decpict Emotional Cycle Kit. It is a kit designed to be used by Emotionally Focused Therapy (EFT) therapists, during a session with a couple. Using DECK helps the therapist and the couple to discover, process, and cope with their "cycle" - the endless loops that drives and maintains their conflicts.
Deck is supplied in a box of approximately 32x24x4 size (1Kg), and contains a board, a set of therapeutic cards, a set of blank papers, and an instructions booklet in English. The instructions can be found also on this page, including other languages versions. You can order the kit here.
