Introduction: Education can play a major role in improving the quality of nurses' performance. The
present study aimed to determine the effect of hand dressing training through group and video 
training on the knowledge of nurses working in different wards.
Methods: In this quasi-experimental study with two groups, 90 nurses working in different wards
of Hazrat Fatima Hospital in Tehran were selected by census method and randomly divided into
two groups of video and group training. Data collection instrument was a questionnaire to assess
the knowledge and performance checklist to evaluate nurses' and researchers’ performance before
and after the training. Data were analyzed using SPSS software version 19, paired sample T test and
independent t-tests.
Results: The levels of awareness in the training group before and after the training were 17.20 ±
1.75 and 18.16 ± 1.14 and in the video training group it was 17.07 ± 1.48 and 17.93 ± 1.45,
respectively. The performance of the training group before and after the training was 77.89 ± 9.36
and 81.69 ± 8.41 and in the video training group it was 74.47 ± 10.79 and 80.33 ± 9.36, respectively.
The results of both groups was better after the training (P < 0.001).
Conclusions: Although both methods were effective in raising nurses’ awareness and performance,
according to numerous advantages of video training including affordability and ability to watch
videos at any time and place and etc., using this method in the training programs is recommended
