Effect of attachment-based interventions on prenatal attachment: a protocol for systematic review

BACKGROUND: Parental attachment was defined as: series of inner behaviors that would cause the infant to develop an intimate relation with his/her parents. This emotional relationship is formed long before birth during the pregnancy and has been associated with psychosocial outcomes for women and children. This relationship is known as one of the major components of the child’s social and emotional development. Parents’ relationship with their fetus could be strengthened using various strategies, but efforts to augment the maternal-fetal relationship have not always been successful. This study aims to conduct a comprehensive systematic review and a meta-analysis survey of the effects of attachment-based interventions on prenatal attachment. METHODS: A comprehensive search of relevant randomized and quasi-randomized controlled trials will be performed in EMBASE (via Scopus), ProQuest, Pubmed, Scopus, Ovid and Web of Science, The Cochrane Central Register of Controlled Trials, SID, MagIran, Irandoc, Barakat Knowledge Network System and Iranian registry of clinical trials website as Iranian databases using English and Persian keywords such as prenatal attachment, relationship, maternal attachment. Only randomized controlled clinical trials conducted between 2000 and 2016 will be included in this review. The study will be selected if their participants were expectant mothers, their partners or both. Our primary outcome will be the effect size of intervention. The quality of experimental studies will be evaluated using CONSORT checklist and Study Quality Guide by Cochrane Consumers and Communication Review Group. Two authors will independently assess the eligibility of the studies. Any disagreements will be resolved through a third reviewer. The risk of bias will be independently determined using the Cochrane Risk of Bias Tool. The quality of the papers will be assessed based on the CONSORT checklist. If possible quantitative data will be pooled in statistical meta-analyzing with random effect model. DISCUSSION: In this review the current state of knowledge on prenatal attachment is examined. Effectiveness of attachment-based interventions during pregnancy is analyzed. Finally, practice and research implications based on analysis of the current status of maternal-fetal attachment are identified. The expected findings will help healthcare providers to develop pregnant women and infants’ health when offering prenatal care.
