Information Content
The ReACH Postpartum Qualitative Harmonization Protocol was performed using the study questionnaires and data dictionaries encompassing the postpartum assessments from 24 studies. This harmonization protocol includes 263 variables targeting mothers, fathers, and children at up to 8 different timepoints for up to 5 years postpartum.
The ReACH Postpartum Qualitative DataSchema covers information on:
* Mothers' socio-demographic and economic characteristics
* Mothers' depression and anxiety
* Fathers' socio-demographic and economic characteristics
* Fathers' depression and anxiety
* Children's physical measures and assessments (height, weight)
* Children's breastfeeding
* Children's cognitive development
Harmonization
- Complete - study-specific variable is the same as DataSchema variable (status detail = identical) or needs transformation to generate DataSchema variable (status detail = compatible)
- Partial - categorical study-specific variable (status detail = proximate) or other types (status detail = tentative) could generate DataSchema variable but with loss of information
- Impossible - study does not collect DataSchema variable (status detail = unavailable) or cannot be used to generate DataSchema variable (status detail = incompatible)
- Undetermined - harmonization status not determined
- Not Applicable - harmonization status is not relevant
