Background: Log book is one of the useful methods for evaluation. Researches have shown that the evaluation of clinical process in nursing students is often accompanied with dissatisfaction. Due to deficiencies in the methods of clinical skills evaluation, the researchers decided to use log book as an appropriate method for evaluating of this group.

Materials and methods: Current quasi-experimental study was done in a military psychiatric hospital in 2014-2015. In this study, 20 nursing students were selected by available sampling method. After completing an internship course of the mental health-1, students’ view was evaluated about the use of checklist. Then, in the internship course on the mental health-2, log book method was performed and a questionnaire was completed by participates. Data were analyzed using paired t-test by SPSS software.

Results: The mean and standard deviation of log book method (32.2±3.27) and traditional (25.35±8.78) method showed a significant difference between them (t=3.489, p=0.002).

Conclusion: Based on our findings, although students’ scores in log book method were higher than the traditional method, the satisfaction from traditional method was more than the log book method. Therefore, a need for further studies and revisions is necessary in other training centers.
