The Validity and Reliability of Social Responsibility Among Senior High School Students

This study aims to test the validity and reliability of social responsibility measurement instruments in secondary school students. A quantitative approach was used involving 248 students from various grade levels selected through purposive sampling techniques in several urban high schools. Data were collected using a structured Google Form-based questionnaire that was developed based on theoretical indicators of social responsibility. Content validity was evaluated by experts in educational psychology and social science, while construct validity was analyzed through Exploratory Factor Analysis (EFA). The analysis results showed a factor structure consistent with the dimensions of empathy, social involvement, accountability, and ethical behavior. Reliability tests using Cronbach's alpha coefficient showed high internal consistency across dimensions (α > 0.80). These findings indicate that the instrument has good validity and reliability and can be used for diagnostic and evaluative purposes in the context of character education. This study makes a significant contribution to the development of a measurement tool for adolescent social responsibility and supports efforts to build responsible young citizens. Further research is recommended to test the instrument in different cultural contexts and educational institutions to strengthen its external validity.
