A short term dyadic psychotherapy intervention for mothers with Post-Partum depression and their babies in the first year of life was developed. The investigators believe that following dyadic intervention mothers will show improvement in depressive symptoms, the quality of the mother-child relationship will improve, and maternal and infant's oxytocin levels will rise.
Subjects: 60 Mothers will be interviewed and diagnosed as suffering from Post-Partum- depression (PPD) according to the Diagnostic and Statistical Manual of Mental Disorders, IV version (DSM-IV), enrolling within 3-8 months postpartum. Mothers will be recruited through social media networks. Additional 40 mothers, 3-8 months postpartum will be assessed and diagnosed as not suffering from PPD or any other psychiatric psychopathology.
Procedure: The baseline assessment will be conducted at the infant's home. A parent-infant interaction will be videotaped and salivary oxytocin samples will be collected from the infant and from the mother.
The women in the PPD group will participate in 8 weeks of dyadic psychotherapy (DP) combining video feedback, or a psycho-educational treatment regarding child development (randomize selection will be made). During the 8-week treatment, salivary oxytocin samples will be collected from the infants and from the mother at the beginning and the end of each session.
Another assessment will be conducted at the infant's home, at the end of the treatment. As in the baseline condition, this assessment will include videotaped parent-infant interaction, as well as salivary oxytocin samples collection from the mother and from the infant. Parent-infant interaction will be filmed and assessed using the CIB Manual (Feldman, 1998) and the synchrony coding system.
Healthy mothers will undergo the same baseline assessment and a second assessment within 2-3 months, and won't get any treatment.

| Post-partum depression- Dyadic psychotherapy- | Other | Mothers and infants will be treated with dyadic psychotherapy focused on interactions, emphasizing eye contact, body language, empathy, and social reciprocity. Dyadic psychotherapy will be administered one time a week during the 8-week trial period, at the subject's home. Each session, approximately 90 minutes long, will include videotaping mother-infant interaction, watching the last session's interaction as a part of video-feedback technique, and discussing main issues in the mother-infant relationship. In addition, each session will begin and end with a- 5-minute episode of affectionate touch and gaze synchrony between the mother and her infant. During the whole therapy-trial, the therapist will also use cognitive-behavioral approach to address the mother's perception of her infant and of herself as a mother. |
| Measure | Description | Time Frame |
|---|---|---|
| Behavioral Assessment of dialogue | Interactions will be coded with the "Coding Interactive Behavior" (CIB) manual (Feldman, 1998), infant version. This version is composed of 37 codes rated on a scale of 1 to 5, as higher score means a better outcome. | trail 1-baseline |
| Hormonal Assays- Oxytocin | Three saliva samples will be collected using Salivettes® at baseline, following interaction, and 20 minutes after end and averaged. All samples will be then stored at -20°C. Salivette will be treated as following: centrifuged twice, at 4°C at 1500 x g for 30 minutes, aliquoted and lyophilized over few days- to concentrate by 4 times. The dry samples will be reconstructed in the assay buffer immediately before analysis using an oxytocin enzyme immunoassay commercial kit (ENZO, NY). The assay preformed according the kit's instruction. The concentration of oxytocin will be calculated using MatLab-7 | trail 1-baseline |
