title: Correlations of visual analog scales with Edinburgh Postnatal Depression Scale.
abstract: BACKGROUND
  The purpose of this study was to search for correlations of scores on the visual analog scales (VAS) taken during the third week postpartum with scores on the Edinburgh Postnatal Depression Scale (EPDS) taken on approximately day 28 postpartum.
  
  
  METHODS
  Thirty-four women filled out six visual analog scales on postpartum days 15-21 and took the EPDS at their 4-week postpartum visit to the clinic. Results were analyzed by simple linear regression and multiple backward stepwise regression.
  
  
  RESULTS
  Responses to all six statements of the VAS correlated significantly with 4-week EPDS scores. Approximately 54% of the variability of 4-week EPDS scores can be predicted by the variability in VAS question 6.
  
  
  CONCLUSIONS
  Relatively small sample size is a moderately limiting factor of this study.
  
  
  CONCLUSIONS
  Mood in the third week postpartum was predictive of EPDS score on postpartum day 28. Mood lability during the third week postpartum was a better predictor of EPDS score on day 28 than the other five measures, including feelings of sadness or anxiety. The EPDS may have potential use with an acceptable degree of accuracy earlier than the standard 4 weeks postpartum.
