Objective: This study was conducted for the purpose of developing a scale that enables nursing students to measure their self-efficacy during the course of clinical training in basic nursing education, and assessing the reliability and validity of a scale.
Study method: Mail survey covering those nursing students, who were in the third and the fourth grade at school, was conducted. Divided them into 3 groups. Study Group 1: 99 students, Study Group 2: 1,895 students, and Study Group 3: 1028 students. The survey content consisted of a preliminary scale for measuring self-efficacy during clinical training, a scale for measuring social skills and each student's fitness for their major field.
Results: In Study Group 1, the students were asked to reply those matters which they felt important in clinical training by using a sentence completion format. And a clinical training self-efficacy preliminary scale (73 items) was developed (N=99). In Study Group 2, a survey was conducted by using a preliminary scale (n=1895), and as a result of exploratory factor analysis, 3 were extracted, which were "Feeling of efficacy in understanding and assisting those surveyed", "Feeling of efficacy in maintaining relationship with friends" and "Feeling of efficacy in maintaining relationship with instructors". Selecting those items, which most closely matched each factor, from Stepwise Exploratory Factor Analysis, a scale of 16 items was developed. The correlation coefficients between the subscales and a scale for measuring social skills were .49, .45 and .50 respectively. The coefficients of reliability (α coefficient) ranged from .88 to .78 and the correlation coefficients between retests were .87, .49 and .70 respectively. Moreover, when a confirmatory factor analysis was done in Study Group 3, the results showed GFI = .95, CFI = .96 and RMSEA = .057 (n=1028).
Conclusion: A self-efficacy scale during clinical training, which consists of 16 items and 3 subscales, was developed, and construct validity and reliability were confirmed. By using this scale, it is possible to measure self-efficacy during clinical training easily.
