Brief summary: Survey experiment to elicit perceived norms about substance use

Detailed description: Health behaviors and health risk behaviors are known to be associated with the extent to which one perceives these behaviors as normative. The canonical example of this phenomenon is taken from the U.S. literature, which has robustly shown that undergraduate students on college campuses tend to drink more heavily and frequently if they believe their classmates drink heavily and frequently, irrespective of their classmates' actual levels and frequency of use. However, there remains little systematic understanding about the best ways to elicit these perceived norms through survey-based research studies. This randomized survey experiment compares different ways of eliciting perceived norms.

Eligibility criteria: Inclusion Criteria:

* All adults who consider Nyakabare their primary place of residence and who are capable of providing consent

Exclusion Criteria:

* Minors younger than 18 years of age, with the exception of emancipated minors
* Persons who do not consider Nyakabare Parish their primary place of residence, e.g., persons who happen to be visiting Nyakabare at the time of the survey or who own a home in Nyakabare but spend most of their time outside the parish
* Persons with psychosis, neurological damage, acute intoxication, or other cognitive impairment (all of which are determined informally in the field by non-clinical research staff in consultation with a supervisor)
