<![CDATA[Introduction: Traffic accidents occur widely across regencies and cities in Central Java, including Kendal Regency, where data indicates 490 incidents resulting in 485 victims with minor injuries and 129 fatalities. Minimizing these impacts requires prompt and appropriate first aid from trained responders, such as Indonesian Red Cross (PMI) volunteers. The success of first aid interventions is heavily influenced by cognitive factors—specifically knowledge—and psychological factors, namely self-confidence. This study aims to assess the self-confidence and knowledge levels of PMI volunteers regarding first aid for traffic accident victims. Methods: This study employed a quantitative, descriptive survey design. The sample consisted of 43 PMI volunteers selected via accidental sampling. Data were collected using a self-confidence questionnaire (adapted from Lauster) and a knowledge assessment questionnaire. Univariate analysis was performed to determine frequency distributions. Results: The respondent profile was predominantly female (60.5%), with an average age of 21 years and a majority holding a high school education (65%). Findings indicate that the majority of PMI volunteers (97.6%) possessed a "Good" level of knowledge. Most respondents also demonstrated a high level of self-confidence (56%), driven by the alignment between cognitive mastery and field experience. Discussion: Based on the findings, it is concluded that all volunteers should be provided with equal opportunities to learn, practice, and actively participate in handling field cases, particularly those involving victims with severe bleeding.]]>
