Conclusion
SECONDARY
Treatment fidelity questionnaires developed to assess treatment delivery and treatment receipt of MT for premature infants and their parents in the LongSTEP study showed good internal consistency and moderate interrater reliability. Treatment delivery scores indicated that music therapists across a wide range of cultural contexts were able to successfully implement the complex behavioural intervention of our MT approach, adhering to the essential elements of the intervention protocol. This indicates the high clinical applicability of the LongSTEP approach to MT in NICU. Parents’ high treatment receipt scores support this notion and indicate specific areas where the intervention benefitted them above and beyond the LongSTEP trial’s primary and secondary outcomes. Parents experienced their own voices as unique resources in relation to their baby and likely developed skills transferable to their daily lives [
