Abstract:
This study investigated whether conscious and preconscious memory features contribute to discrimination between depressive and somatoform disorders. Thirty-one participants fulfilling the diagnostic criteria for a somatoform disorder and 28 participants fulfilling the criteria for depression were examined within the framework of the process-dissociation paradigm using neutral, health-threatening, and general threatening words in a lexical decision task. Parameters of conscious memory, preconscious memory, and chance were used to compare memory features of both the groups. There was an inverse relationship between conscious and preconscious memory effects for health-threatening stimuli in the group of patients with somatoform disorders but not in the group of depressive patients. Patients with somatoform disorders showed a significantly lower level of conscious memory for health-threatening stimuli than depressive participants. Compared to depressive patients, a more dynamic relationship between decreased conscious and increased preconscious memory for health-related stimuli seems to be characteristic for patients with somatoform disorders.Keywords: cognitive characteristics; depression; process dissociation procedure; somatoform disorder
