title: Anhedonia, suicide ideation and dexamethasone nonsuppression in depressed patients.
abstract: In the search for a valid analysis of a number of operationalised symptoms common to depressive behaviour, a study was performed comprising 46 patients showing depressive symptoms, according to operationalised criteria and as part of which all agreed to undergo the following tests: (a) psychiatric: Present State Examination; (b) psychological: Hamilton Rating Scale, Montgomery-Asberg Rating Scale, State-Trait Anxiety Inventory, Beck Suicide Ideation Scale, Chapman Anhedonia Scale, Mood Scale, Sleep Quality Scale, Activities Scale, Social Support Scale, Questionnaire on Recently Experienced Events and the Paykel Life Events Interview; and (c) biochemical: Dexamethasone Suppression (DEX) Test. After gathering different depressive subgroups, based on operationalised symptoms, a dichotomy was made in the distributions of the (an)hedonia, suicide ideation and DEX-(non) suppression scores. This study may indicate that anhedonia, suicide ideation and DEX-nonsuppression are the opening to the identification of a subgroup of depressed patients. This symptom complex could not definitely be identified on the basis of existing DSM-III diagnostic entities, because of the known fact that this method of classification is not appropriate for our purposes in revealing pathophysiological processes. It is suggested, therefore, that these symptoms might prove to be the anchor-point from which to reach a better insight into the aetiology and pathogenesis (i.e. the final common pathway) of depression.
