The psychoanalysis proceeds inductively, and the behaviour therapy – deductiveli.Consequently, the psychoanalysis resorts to a historical – longitudinal investigation, starting from the individual`s unmemorable beginnings, unlike the behaviour therapy, which cuts a transversal section, by performing an actual simptomtic inventory. Contraindications of psychoanalysis involve severe psychiatric conditions such as psychoses, which require psychopharmacological treatment. Also, patients with a weak Ego force are contraindicated, to whom the effort required by psychoanalysis itself can psychologically disorganize them, with the danger of suicidal pulses or regressive states or psychotic development.
