ABSTRACT
This chapter lists the main attributes of The Diamond Model and details the stages by which this model has been constructed and validated. The Diamond Model is multi-systemic, integrative, linguistically uniform and rigorous. Its ingredients have been explicated in the theoretical languages of information processing, semiotics and cybernetics. It is an explanatory model, in the sense that the multi-systemic etiology of each case and the mechanisms of spontaneous and therapeutic change are explained by the principle of simplicity, comprising the criteria of comprehensiveness, parsimony, consistency and plausibility. It is a systematically eclectic model, admitting any therapeutic method and techniques, of which the change mechanism fits into the multi-systemic diagnostic evaluation and the derived therapeutic strategy and tactics.
