The study used only items with a content validity index (CVI) score of .80 or higher. The author of this study further revised terms so that they were appropriate for the subjects.The scale included 10 items to be rated on a 7-point scale, and the scale scores ranged from 10 (lowest) to 70 (highest).The hypotheses of this study are as follows: Hypothesis 1.Scores of communication efficacy scores will be higher in the experimental group receiving the TBL program than in the control group with the lecture-style instruction. Scores of communication ability will be higher in the experimental group receiving the TBL program than in the control group with the lecture-style instruction. Scores of learning satisfaction will be higher in the experimental group receiving the TBL program than in the control group with the lecture-style instruction. Study Design This was a quasi-experimental study with a nonequivalent control group pre-post test design to identify the effects of a TBL program for communication competence improvement on communication competence of nursing students. Sample and Recruitment The subjects were selected through convenience sampling from an accessible population of sophomore students in the Department of Nursing at two 4-year universities with similar size and levels. This study included nursing students without previous experience of communication education, who were informed about the purpose of the research and gave their informed consent for participation.All instruments were approved for use via email from tool developers.
Unlike PBL or SBL, TBL extensively uses learning strategies that maximize learning effectiveness by increasing student participation .
The minimum number of subjects required was 28 to perform an independent samples t-test using the GPower program, version 3.1.2.
The significance level (a) of p was set at .05, with statistical power at .90 (1-β), and an effect size (d) of .80.
The Korean Accreditation Board of Nursing Education (KABON)  has recently recommended the establishment of a performance-based education system, and the improvement of education programs through nursing education accreditation in order to produce competent nurses.
The KABON has included communication ability as one of 12 core competencies that nurses need to acquire through nursing education programs.
