Abstract


This study was conducted to validate the measurement model of the awareness of e-waste management among secondary school students. The study’s respondents consisted of 1,000 students from Malaysian secondary schools, who were selected using a simple random sampling technique based on their school level. The constructs studied were knowledge, attitude, and the practice of e-waste management. The data were analysed descriptively to determine the reliability value of Cronbach’s alpha, whilst confirmatory factor analysis (CFA) was used to obtain a three-factor solution using SPSS 22 and AMOS 20. The analysis revealed that the Cronbach’s alpha value was above 0.70, indicating a high classification level. The CFA analysis of the measurement model showed that the three-factor solution was compatible and acceptable based on the recommended indicators. Thus, the 29-item measurement model developed was appropriate to measure the awareness of e-waste management among secondary school students.
