The Berkman-Syme Social Network Index (SNI) is a self-reported questionnaire for use in adults aged 18–64 years old that is a composite measure of four types of social connections: marital status (married vs. not); sociability (number and frequency of contacts with children, close relatives, and close friends); church group membership (yes vs. no); and membership in other community organizations (yes vs. no). This measure is a questionnaire to assess the type, size, closeness, and frequency of contacts in a respondent’s current social network. This measure allows researchers to categorize individuals based on social connectedness and can highlight those at risk for social isolation.
