The present paper describes a study on the intake interview narratives of psychotherapy patients with computer assisted content analysis methods. 46 psychoanalytic first interviews of patients suffering from depression or anxiety disorders were analysed with the Regressive Imagery Dictionary (RID), a computer assisted content analysis method with 43 subcategories, which were sumed up to three main categories: Primary Process, Secondary Process, and Emotion. Comparisons between different subgroups of this sample were made: Anxiety vs. depressive patients, and East Germans (Magdeburg) vs. West Germans (Düsseldorf). Significant correlations were found between the Primary Process subcategories Passivity and Regressive Cognition, and East German patients, as well as correlations between the Primary Process subcategory Orality, and anxiety patients. The results confirm our hypothesis, that the psychotherapist-patient-interaction sequences, which are the basis of diagnostic categorization, enclose as well elements which are specific for the disorders under study as elements which are specific for sex and culture (east vs. west). The study contributes to the identification of specific text markers, which can be found in the narratives of patients suffering from neurotic depression vs. patients with phobia and panic disorders. The results of the study are compared with a previous qualitative study. Using the ideal-type concept, our qualitative content analysis study showed as characteristic features of depressed patients overidentification with social roles and norms, feeling of being dependent and injured by another person, problems of self-esteem, shyness, and unfulfilled wishes to be loved and accepted. In contrast, phobic patients characterized the own personality as normal and without any problems in a stereotype way, at the same time feeling misunderstood and exploited by other persons, feeling as an outsider and left alone, and being no more able to compete with others.
