Effects of a Digital Educational Package Combined with Coaching the GROW Model on Knowledge and Skills in Chronic Obstructive Pulmonary Disease

Abstract

     This study was a quasi-experimental research design aimed at examining the effects of a Digital Educational Package based on the GROW model on knowledge and skills related to chronic obstructive pulmonary disease (COPD). The sample size was calculated using G*Power. The researcher set the level of statistical significance (α) at .05 and the power of the test at .80, with a medium effect size. The calculated sample size was 72 participants. To prevent attrition, the sample size was increased by 10%, resulting in a total of 80 participants. Simple random sampling was used to assign participants into an experimental group and a control group, with 40 participants in each group. The experimental group received standard nursing care along with the Digital Educational Package based on the GROW model, while the control group received only standard nursing care. The research instruments included the Digital Educational Package based on the GROW model and a knowledge and skills assessment questionnaire. The statistical analyses included frequency, percentage, mean, standard deviation, paired t-test, and independent t-test.

     The results showed that in the experimental group, the post-test knowledge and skill scores were significantly higher than the pre-test scores at the .05 level of statistical significance. In the control group, there was no significant difference between pre-test and post-test knowledge and skill scores. Additionally, before the intervention, there were no significant differences in knowledge and skill scores between the experimental and control groups. However, after the intervention, the knowledge and skill scores between the two groups were significantly different at the .05 level.
