Trial Outcomes & Findings for Evaluating a Coparenting Breastfeeding Support Intervention (NCT NCT01536119)

NCT ID: NCT01536119

Last Updated: 2014-01-24

Results Overview

Exclusive breastfeeding will be determined by asking the mother what she has fed her baby in the last 24 hrs and what she usually feeds her baby. This is consistent with the World Health Organizations definition of exclusive breastfeeding and full breastfeeding described by Labbok and Krasovec (1990). This is defined as no food or liquid other than breast milk given to the infant; however, undiluted drops or syrups consisting of vitamins, minerals supplements or medicines are included (Breastfeeding Committee for Canada, 2006; WHO, 2010).

Any breastfeeding was measured by asking the mother what she had fed her infant in the last 24 hours and what she usually feeds her baby. Any breastfeeding indicated the mother was breastfeeding or providing her infant with expressed breastmilk and this included combined feeding with formula.

Breastfeeding support is defined as the appraisal, emotional, informational and instrumental support the mother receives from her partner. This component of coparenting will be measured using the Postpartum Partner Support Scale (PPSS), which is a 24-item self-report instrument. The items are rated on a 4 point scale to produce a summative score ranging from 25-100. Two negative items are reversed scored and the higher scores indicate higher levels of postpartum-specific partner support.
