A video analysis of the non-verbal behaviour of depressed patients before and after treatment.
Using videotaped interviews of depressive in-patients, which were recorded on day 0 and day 21 of antidepressive pharmacotherapy, the behavioural structure of the syndromal main aspects, retardation and agitation, was analysed. This analysis was done on the basis of non-verbal behaviour only. A factor analysis was carried out on the observational data. Three independent factors, constituting together the clinical picture of endogenous depression, could be defined: one factor of retardation and two different factors of agitation. The importance of such non-verbal analyses for a more differentiated diagnostic evaluation, on the one hand, and to provide more insight into the diagnostic process as such, on the other, is pointed out. Additionally it was found that syndromal complexity decreases in a characteristic manner along with clinical improvement.
