COVID-19 pandemic has caused havoc all over the world. India is going through a challenging situation as the number of infected/positive cases are increasing day by day. With strict preventive measures and restrictions by the Indian Government in the form of nationwide lockdown, the citizens are going through a range of psychological and emotional reactions, fear and uncertainty being one of them. This study was conducted with the aim of exploring the reactions of COVID-19 and lockdown on the mental health and emotional well-being of students. In this study data were collected in respect of reaction towards mental health and emotional well-being of students during lock-down. Reactions of college going students were assessed with the help of reaction towards mental health and emotional well-being scale prepared by the investigator. The sample comprised of 67 randomly selected graduate and post graduate students of Haryana state. The data was collected from both boys and girls living in both urban and rural areas. Data were analyzed by computing percentages. Results revealed that more than 60% students responded positively in 19 items which shows that students were keeping themselves busy in different tasks at home. On the other hand, more than 60% students responded in four items had negative feeling that they are tired of staying at home during lock-down; they feel nervous when they see news of covid-19 on TV; they feel that social isolation increases anxiety in the person being isolated; they are unable to manage their feelings/emotions during Covid-19; and uncertainty of today makes life intolerable. Additionally, the majority of the students received increased support from friends and family members, increased shared feeling and caring with family members and others. In conclusion, the COVID-19 pandemic was associated with mild stressful impact in the sample, even though the COVID-19 pandemic is still ongoing. These findings would need to be verified in larger population studies.
