Predictors of (non-) response in depressed outpatients treated with a three-phase sequential medication strategy

The predictive value of eight domains or sets of variables including sociodemographic aspects, premorbid history, symptomatology, personality, social and diagnostic data are evaluated in depressed outpatients with a Hamilton Rating Scale for Depression (HRSD) score of at least 14. Patients were treated using a three-phase sequential treatment strategy. Of the 119 patients, 88 completed the trial. The HRSD-score at the end of phases I, II or III was used as an outcome measure. Patients with an initially high HRSD-score and an obsessive-compulsive personality had a greater chance of recovery, while patients with somatization and a passive-aggressive personality had less of a chance of recovery. Variables involving psychiatric history, premorbid history or symptomatology of the depression, were not significantly related to outcome. The endogenous/non-endogenous distinction was not a predictor of response.
