Methodological choices for an economic evaluation of a combined psychosocial and nutrition treatment intervention for children with severe acute malnutrition: The FUSAM trial in Nepal.

As a public health burden, severe acute malnutrition (SAM) among children has been increasingly studied to determine the optimal combination of treatment approaches. Among the new approaches is the addition of early childhood development sessions to standard nutrition-based treatment for SAM which can enhance both nutrition and development outcomes among young children. However, few studies demonstrate the relationship between the costs of such combined programs and the benefits accrued to the children and their caregivers. This article describes our experience of designing and conducting an economic evaluation alongside a cluster randomized controlled trial assessing a combined nutrition and psychosocial intervention for the treatment of SAM in children aged 6-24 months in Nepal. We present key lessons learned regarding methodological choices, the challenges of field data collection, as well as study adjustment when data analysis did not unfold as anticipated. With the view to transparency, this manuscript provides some clarifications on the evaluation processes for funders and policy makers on what economic evaluations entail and what information they convey for the purpose of supporting policy decision-making around limited resource allocation.

The Transgenerational Transmission of Trauma: The Effects of Maternal PTSD in Mother-Infant Interactions.

The objective of the study was to examine the process of mother to infant trauma transmission among traumatized mothers in humanitarian contexts. We investigated the impact of mothers' post-traumatic stress disorder symptoms on the quality of the dyadic interaction by conducting a microanalysis of mother-infant interactions at specific moments when trauma was recalled, compared to more neutral moments. Twenty-four mother-infant dyadic interactions of traumatized mothers and children aged from 1.5 to 30 months Central Africa, Chad, and Cameroon were videotaped during three sequences: a neutral initial session (baseline) exploring mothers' representations of the infant and of their bonding; a second sequence, "the traumatic narration," in which mothers were asked to talk about the difficult events they had experienced; and a third sequence focusing on a neutral subject. Three minutes of each sequence were coded through a specific grid for microanalysis [based on the scales developed at Bobigny Faculty of Medicine and the work of (1)], according to different communication modalities (touch, visual, and vocal), for both the mother and the child. Impact of traumatic event (IES-R), the level of depression and anxiety (HAD) were investigated in order to have a holistic understanding of the trauma transmission mechanism. The data analysis highlighted significant differences in mothers, children and their interaction during the "traumatic narration": mothers touched and looked at the infant less, looked more absent and smiled less, and looked less at the interviewer; infants looked less at the interviewer, and sucked the breast more. The mother-child interaction "infant self-stimulation-mother looks absent" and "Infant sucks the breast-mother looks absent" occurred more often during the mothers' traumatic narrations. The "absence" of the mother during trauma recall seems to have repercussions on infants' behavior and interaction; infants show coping strategies that are discussed. We found no significant associations between interaction and infant gender and age, the severity of traumatic experience, mothers' depression and anxiety symptoms, and the country of residence. The results of the microanalysis of interaction can shed light on the fundamental role of intermodal exchanges between mother and infant in trauma transmission during mothers' trauma reactivation.
