Responding to the psychosocial health needs of the vulnerable population has been considered as a significant public health issue that must be addressed through access to public health professionals. The study adopted a quasi-experimental design to evaluate the impact of a training program on nurses and teachers' knowledge of psychosocial health needs of vulnerable children and the impact this had on children's resilience and psychosocial health outcomes (self-esteem, social connection, anxiety, and depression). The result showed a significant increase in the knowledge mean scores of both nurses and teachers 6 weeks post intervention. Children's depression scores significantly reduced post intervention. Their resilience, self-esteem, and social connection were also significantly improved, while no significant reduction was found in their anxiety scores. The results of the pilot study suggest that a more rigorous study be conducted to further ascertain the effectiveness of the various interventions used in this study while taking into consideration the challenges raised by the authors.
