Title : Process and Outcome Evaluations of Interventions to Promote Voluntary Exercise Training Among South Korean Firefighters


The main aim of the present study is to evaluate reach, dose, fidelity, and outcomes of the interventions for promoting voluntary exercise training among South Korean firefighters. Four interventions for promoting voluntary exercise training among firefighters (i.e., virtual reality exercise system intervention, poster intervention, monitor intervention, and wearable health device intervention) were performed in a fire station located in Seoul, South Korea. To evaluate reach and dose received related to each intervention, participants were asked to answer several simple questions. Three process evaluators completed a 20-item survey to share their impressions related to the quality of intervention delivery. Pairedttest was used to examine mean changes in primary (i.e., mean minutes of exercise training per week) and secondary outcomes (i.e., beliefs and intention) between pre- and postinterventions. More than 60% of participants experienced monitor and wearable health device interventions. Process evaluators tend not to agree with a statement saying that the number of the virtual reality exercise equipment was appropriate. Among firefighters who participated in exercise training less than 150 min per week at 1-month follow-up, mean minutes of exercise training per week increased by 67.95 min after interventions. Future studies need to examine whether the monitor and wearable health device interventions effectively increase exercise training participation among firefighters in other fire stations located in Seoul, South Korea.

What will audience learn from your presentation?

  • As intervention complexity can cause poor implementation of interventions, it is essential to examine whether interventions were delivered or received as planned. This research can help researchers and practitioners to evaluate how well each intervention was delivered or received and, therefore, increase the ability to make valid judgment about outcomes.
  • The results of process evaluation, together with outcome evaluation, has the capacity to suggest future directions for interventions in different settings.
