To investigate in non-depressed perinatal women, whichBeck Depression Inventory-II (BDI-II) and Postpartum Postpartum DepressionScreening Scale (PDSS) scores and proportions of symptomatic items significantlydiffer through the perinatal period.

273 women were assessed with the Diagnostic Interviewfor Genetic Studies, BDI-II and the PDSS at the third trimester of pregnancy/T0(mean age =29.42±7.159 years; mean weeks gestation=32.6±3.61),three/T1, six/T2 and twelve/T3 months postpartum.

Significantlyhigher scores in T0 than in T1/T2/T3 and in T1 than in T2/T3 were found for: Total PDSS, Sleeping-Eating Disturbances, Emotional Liability, Total BDI-II andits dimension Somatic-Anxiety. Only T0 and T1/T2 didnot significantly differ in Anxiety/Insecurity, Mental Confusion, and Loss of Self. In Guilty/Shame only T1 was significantly higher than T3. Suicidalthoughts were significantly higher in T0 than T1 and lower in T1 than T2/T3.

Theproportions of symptomatic items systematically and significantly decreased fromT0 to T3 in changes of sleep, loss of interest in sex, feeling overwhelmed. Significantlyhigher symptomatic proportions in T0 than in all post-partum moments were foundfor: loss of energy, irritability, fatigue, changes in appetite, crying, indecisiveness and worthlessness (these last three also higher in T1 than inT3). Agitation was significantly higherin T1 than in T0. All the cognitive-affective symptoms from BDI-II and PDSSdid not differ.

From pregnancy to the twelfth month postpartum the depressivesymptomatology, particularly somatic-affective symptoms, significantlydecreased. However even for the women who are not clinically depressed, theperinatal period requires considerable psychological adjustment.
