Purpose: This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. Methods: A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, chi(2)-test, t-test, and ANCOVA with the SPSS 18.0. Results: The experimental group showed more %26apos;self-efficacy for drug dosage calculation%26apos; than the control group (t=3.82, p%26lt;.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p%26lt;.001), with regard to %26apos;metric conversion%26apos; (t=2.25, p=.027), %26apos;table dosage calculation%26apos; (t=2.20, p=.031) and %26apos;drop rate calculation%26apos; (t=4.60, p%26lt;.001). There was no difference in improvement in %26apos;anxiety for drug dosage calculation%26apos;. Mean satisfaction score for the program was 86.1. Conclusion: These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.
