Conclusion
This study found positive attitudes toward adopting CombinADO study interventions among HIV care providers for AYAHIV in Nampula, Mozambique. According to this study, developing needs-based interventions and understanding the contextual factors before active implementation is key to promoting HIV interventions in healthcare settings. Including service providers in developing interventions addressing their clients' needs and considering factors specific to their work context is likely to improve attitudes towards interventions and, accordingly, the adoption of interventions. Furthermore, our study shows that perceived adequacy of resources―in this study, training and human resources―may be necessary for shaping attitudes towards adopting new interventions in this and similar healthcare settings. Achieving success in the implementation process of novel interventions, especially those with complex components, requires understanding implementers' perspectives, as well as their characteristics and their work contexts.
