title: The cut-off points of the Depression and Somatic Symptoms Scale and the Hospital Anxiety and Depression Scale in detecting non-full remission and a current major depressive episode.
abstract: OBJECTIVE
  This study aimed to ascertain the cut-off scores of the Depression and Somatic Symptoms Scale (DSSS) for non-full remission (FR) and a current major depressive episode (MDE) and compare the discriminative abilities of the DSSS and the Hospital Anxiety and Depression Scale (HADS).
  
  
  METHODS
  One-hundred and nineteen depressive outpatients who completed a 6-month follow-up were used to ascertain the cut-off scores for non-FR, defined as a Hamilton Depression Rating Scale score ≥ 8; another 214 consecutive outpatients were assessed to identify the cut-off scores for a MDE, as defined by the Structured Clinical Interview for DSM-IV-TR. Receiver operating characteristic (ROC) analysis was used to ascertain the cut-off scores.
  
  
  RESULTS
  The area under the ROC curve was greatest for the DSSS depression subscale (DS), followed by the HADS depression subscale (HADS-D). The cut-off scores for non-FR were a DS score ≥ 9 (sensitivity and specificity: 88.7 and 71.9%, respectively) and a HADS-D score ≥ 8 (77.4 and 84.2%), and the cut-off scores for a MDE were a DS score ≥ 19 (86.3 and 75.6%) and a HADS-D score ≥ 11 (77.9 and 76.5%).
  
  
  CONCLUSIONS
  The DSSS and HADS can be used to distinguish different depressive states. The results demonstrated the discriminative validity of the DSSS and the HADS.
