Background This study aimed to increase safety knowledge and behaviour of US Hispanic custodial workers in healthcare through a culturally appropriate training and monitoring process.

Method A single-group, repeated-measures, pre-test and post-test design was used to examine training effectiveness across four sets of behaviours with 23 Spanish-speaking workers.

Results Small group, lecture-style training in Spanish with pictures and video resulted in significant improvements in knowledge and behaviour. However, additional analyses show that behavioural feedback was the critical component in improving safety behaviour during transfer of training.

Discussion Findings from reaction, knowledge, behaviour and results measures suggest that group training and graphic feedback is culturally appropriate and effective with Hispanic workers. Further investigation is needed to understand cultural factors that facilitate effective development and delivery of safety training and feedback to US Hispanic workers.
