Study Overview
Brief Summary
Rationale and Hypotheses of the Current Research: the investigators speculate that mothers suffering from PPD exhibit high levels of depression and low levels of OXT, hence experiencing the interaction with their child as less rewarding, which in turn promote further depressive symptoms and interfere with child development. While dyadic psychotherapy has been studied in this context, it is unknown which depressed women will respond to this type of therapy, and whether such a response is mediated by the pro-bonding effect of oxytocin.
The aim of this study is three-fold:
- To study the effect of the administration of a single dose (24IU) of oxytocin on cerebral circuit processing and connectivity of empathy and attachment.
- To examine whether the clinical response of mothers suffering from postpartum depression to short term dyadic psychotherapy (based on improved mother-child interactions) can be predicted by a unique brain response pattern to oxytocin.
- To assess the relationship between levels of oxytocin in mother and baby and the effectiveness of psychological dyadic treatment on mothers suffering from postpartum depression.

Arms & Interventions
postpartum depression
Women suffering from postpartum depression, assessed by fMRI and then treated by dyadic psychotherapy
- All participants will undergo two functional brain scans at the Tel Aviv Medical Center. The two scans will take place one week apart, one scan will include administration of oxytocin (24IU) and the other will include the use of placebo (the order in which the two different treatments is applied will be random).
- All women in this group participate in 8-weeks of dyadic psychotherapy (DP) at the outpatient Psychiatric Department, Tel-Aviv Medical Center.
- A final end-of-study clinical evaluation, will be conducted at the end of 8 weeks. The evaluation will include a psychiatric evaluation, the MADRS, and a physical examination, the mother-infant interaction will be videotaped, and the YIPTA, BDI, EPDS & STAI will be administered. Salivary OXT samples will be collected from the mother and from the infant and infants will undergo a developmental assessment.
Intervention: Oxytocin (Drug)

Outcomes
Primary Outcomes
Interactional measures-CIB
Time Frame: pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year
The Coding Interactive Behavior Manual (CIB) (Feldman 1998), a well-validated system for coding dyadic interactions, by individuals blind to the study group that the participant is a member in. The following behaviors will be compute: Parents behavior; Child behavior; Dyadic behavior; Lead-Lag Relationship
Interactional measures-Noldus
Time Frame: pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year
Micro-analytic coding of synchrony- on a computerized system (Noldus, The Vaggenigen, Netherlands), coded on a computerized system that allows for .01-second exactness. Consistent with previous research on parent-infant synchrony (Feldman and Eidelman, 2004, 2007). Four non-verbal categories of parenting behavior and four non-verbal categories of infant behavior will be coded and each category will include a set of mutually exclusive codes.
Effect of the administration of oxytocin on cerebral circuit processing
Time Frame: Two functional brain scans one week after admission to the study (week2)
1. This paradigm assesses empathic responses to images of individuals experiencing sad, anxious and happy events. Images are preceded by social context (i.e. "this person just won the lottery"). Control condition presents participants with images of people performing everyday actions. 3.we generated 15 short screenplays containing triggers for both types of empathy. Each of the screenplays depicts a situation in which the characters pose a negatively-valenced bodily state (e.g. crying, itching, choking), which we expect to elicit embodied simulation in the viewer. 2. This paradigm examines maternal FMRI responses to infant related video vignettes. Stimuli include movies of mothers' own infant vs strange infant during solitary play and mother-infant interaction.
Secondary Outcomes
- Maternal depression symptoms measures- BDI(mothers will complete the BDI once a week during the 8-week trial, as well as in the pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year)
- Maternal thought and action measures(mothers will complete the YIPTA twice; in the pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year)
- Maternal depression symptoms measures - EPDS(pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year)
- Physiological measures-Salivary OXT(both mothers and infants will give six saliva samples; once a other week during the 8-week trial, as well as in the pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year)
- Maternal anxiety measures-STAI(mothers will complete the STAI once a week during the 8-week trial, as well as in the pre (baseline at week 1) and post (week 11) experimental trial assessments. Data will be presented up to 1 year)
