The aim of the study is to identify factors that may have influenced students’ mental health during the COVID-19 pandemic. The qualitative approach was used to obtain data from respondents. Specifically, semi-structured interviews were conducted among secondary school students in Kedah, Malaysia. The results showed that Home-Based Teaching and Learning (PdPR), teacher support and use of technology were among the factors revealed by students that influenced their mental health during the pandemic. This study adds to the literature on students’ mental health by describing the interview responses among secondary school students in Malaysia. The findings of the study can be used by stakeholders such as the Ministry of Education (MOE) Malaysia and the National Population and Family Development Board (LPPKN) to formulate several strategies to reduce students’ mental health problems in Malaysia.
