Development and Evaluation of a Home-visit Simulation Scenario for Elderly People with Diabetes Mellitus Who Live Alone.

: Developing and evaluating a simulation scenario for community nursing practicum students.: One group, pretest posttest design with 87 nursing students.: Data were collected through questionnaires. The simulation was based on Jeffries' simulation model and used a standardized patient.: Self-efficacy and critical thinking increased with the developed simulation. Positive correlations were identified among critical thinking, learning effectiveness, and self-efficacy.: The home-visit simulation scenario was effective in providing students with a problem-solving experience in conditions similar to reality.: Further research is needed to develop various types of community simulation scenarios to enhance competency for community health practice.
