Psychometric assessment of the Correa–Barrick Postpartum Depression Scale

IntroductionEmpirical evidence has suggested an association between mood and color sensitivity. The purpose of this study is to report on the psychometric properties of a new postpartum depression rating scale while at the same time showing a correlation between depression severity and impaired color sensitivity.MethodsUsing a survey design of a sample of 17 postpartum patients, color sensitivity was assessed by the patient's response to a self-report depression scale item, “I notice that everything seems gray/cloudy/drab/lacking color”.ResultsThere was a statistically significant finding between color sensitivity and depression, r = .50, P < .05. Based on classical test theory, findings also supported the validity and reliability of the new scale.LimitationsThe limitation of the study was the small sample size, but it also suggests that the findings seem particularly robust in view of this.ConclusionsThis scale could be used in clinical practice to detect early signs of depression for prompt intervention. Referral should be made to mental health providers for follow-up to insure that the mother is not psychotic or so depressed that she cannot care for the baby. Color sensitivity impairment and depression severity has been replicated several times with different samples. It is worthwhile pursuing the pathophysiological basis for this.
