Introduction: Optimal antenatal nutrition, physical activity and gestational weight gain (GWG) confer positive outcomes for mother and child. txt4two is a multi-modality intervention that aims to promote healthy nutrition, physical activity and GWG in pregnant women. Delivery modalities include health professional introduction, tailored, bi-directional text messages, information website, videos, and chat room (Facebook®). Program components were developed and mapped to behaviour change techniques and included goal setting and self-monitoring. A txt4twofeasibility RCT (n=91) demonstrated a significantly lower GWG (7.8kg + 4.7 versus 9.7 kg + 3.9; p= 0.041) and smaller reductions in physical activity (p=0.001).
Following the feasibility trial, another antenatal service wished to comparatively evaluate a pragmatic implementation of an adapted version of txt4two. Modifications included a comparison of three modes of initial engagement for health professional introduction (F2F, group, telehealth) and embedded other txt4two modalities into the antenatal platform.
Transferring a research program to embed in another context brought up numerous implementation bridges (facilitators) and areas for negotiation.

Areas for negotiation
Conclusion: As we move beyond pilots and embed research programs within health services, we need to understand the facilitators and barriers to implementation to strengthen the evidence for the refinement of implementation plans. Further dialogue is also required to understand the implementation transformation of programs and the impact on program fidelity and quality and subsequent health outcomes.
