Welcome to LASI-DAD
Description: Real Time Insights (RTI) COVID-India is a longitudinal study of people aged 18 and older, living in private households in India. Its sample was drawn from a nationally representative cohort, the Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD). Its main goal is to provide insight on the COVID-19-related changes in the social, economic, institutional, and policy environments in India. The survey elicits information about demographics, COVID-19 awareness, COVID-19 avoidance behavior, COVID-19 testing and symptoms, COVID-19 vaccination, economic effects of COVID-19, health, access to healthcare, food security, informal caregiving, cognition, depression, depression and anxiety, isolation and social contact, and discrimination.
|Age Eligibility||Age 18 and older|
|People Interviewed per Household||One randomly selected adult male and one randomly selected adult female per round|
The RTI COVID-India interviews were carried out every two months using computer-assisted telephone interviewing (CATI) between May 2020 and January 2022. To ensure high-quality data collection, the consent form and questionnaire were translated into 12 languages: Hindi, Kannada, Malayalam, Gujarati, Tamil, Punjabi, Urdu, Bengali, Assamese, Odiya, Marathi, and Telugu.
The RTI COVID-India Wave 1 sample included 1,521 households containing 2,836 individuals. At Waves 2 through 8, additional households were added to the sample if they participated in Wave 1 of LASI-DAD and had a valid phone number. In addition, if a respondent was unavailable at a subsequent wave, an additional randomly selected household member was selected for an interview instead. As a result, it is possible to have more than two respondents interviewed per household. Also, at Wave 3, all primary LASI-DAD respondents with valid phone numbers were invited to participate.
