Psychometric Evaluation of the Mock Code Self-Efficacy Scale.

AIM: This study's purpose is to psychometrically evaluate the Mock Code Self-Efficacy Scale. This tool was developed to measure senior baccalaureate nursing students' level of self-efficacy as it pertains to mock codes.

BACKGROUND: Cardiopulmonary resuscitation is an essential component of nursing education.

METHOD: The Mock Code Self-Efficacy Scale was analyzed for item characteristics, face validity, content validity, reliability, and dimensionality in a sample of senior-level nursing students (n = 153) enrolled in a critical care nursing course.

RESULTS: The scale was found to be multidimensional with reliabilities ranging from .75 to .87. Items evidenced a ceiling effect, perhaps due to the instruction given prior to completing the instrument. The instrument evidenced both content and face validity.

CONCLUSION: The instrument now can be used to assess if increased self-efficacy is a mediating variable for students to correctly transfer skills learned in a mock code to the clinical setting.
