Development and Validation Instrument for Assessment of Competence in Electrocardiogram Rhythm

OBJECTIVE: This study aimed to develop and assess three instruments to evaluate student competence in interpreting electrocardiograms (ECGs). METHODOLOGY: The study was conducted within a nursing education program in Indonesia in 2022, involving a sample size of 73 participants. This research employs a research and development framework utilizing the Tessmer Method. Three assessment instruments were developed to evaluate students' ECG interpretation knowledge, skills, and self-confidence. These instruments underwent psychometric analysis, which included Evaluation of face validity, content validity, structural validity, and reliability assessments focusing on internal consistency and stability. RESULTS: The findings indicated that the interpretation competency instruments denoted as 3 ECG were valid, as they effectively measured the intended constructs, achieving an average validity value of 0.87. The instruments assessing knowledge, skills, and self-confidence exhibited a Content Validity Index (CVI) value of 1 or greater. Furthermore, these instruments demonstrated reliability, with Cronbach's alpha coefficients recorded as follows: Knowledge: 0.913, Skills: 0.855, and Attitude: 0.904. CONCLUSION: The three instruments for evaluating nursing student's knowledge, skills, and self-confidence effectively assess their competency in interpreting ECGs. Knowledge evaluates theoretical understanding; Skills measure practical ability to analyze ECGs; Self-Confidence assesses students' belief in their skills, influencing performance in clinical settings. Together, these tools offer a comprehensive framework to gauge nursing students' proficiency in this critical healthcare area.
