<![CDATA[Theory of Planned Behavior (TPB) is a social psychology theory which explained that someone's tendency to behave is affected by their intention. This theory is often used to predict behavioral intention in health workers by measuring some aspects such as attitude, subjective norm, and self-efficacy. As a prospective health worker who equipped with knowledge and skills about Cardiopulmonary Resuscitation (CPR) during the educa tion phase, we expect that nursing students will have a good intention to become by stander CPR in Out of Hospital Cardiac Arrest (OHCA). The aim of this study was to apply TPB in identifying factors that influence nursing student's intention to perform bystander CPR. This was a quantitative study with a cross-sectional approach. The re search population was an undergraduate nursing student in Malang. As many as 108 respondents were carried out by using the proportional sampling technique. Data were collected once using a questionnaire that included: attitude, subjective norm, self-efficacy, and intention to be a bystander CPR. Chi-square test revealed that the relationship be tween independent variables and intention to be a bystander CPR were: attitude p=0,00, self-efficacy p=0,00 and subjective norm p=0,00. The result of multivariate analysis with logistic regression showed that: attitude p=0,004 (OR=5,279), subjective norm p=0,001 (OR=5,824) and self-efficacy p=0,001 (OR=5,709). This study concluded that there was a significant relationship between attitude, subjective norm, and self-efficacy with inten tion, where the subjective norm was the most dominant factor associated with intention of nursing student to be a bystander CPR.]]>
