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.

Arm && Interventions

Group	Intervention	Description
Experimental: V1: Binary Response Options	Survey questionnaire	As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific wording. Each question in this version of the survey questionnaire has binary (yes/no) response options.
Experimental: V2: Categorical Response Options	Survey questionnaire	As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific wording. Each question in this version of the survey questionnaire has categorical response options: all or almost all; more than half, but fewer than 90%; fewer than half, but more than 10%; very few, or no one
Experimental: V3: Open-Ended Numerical Estimate	Survey questionnaire	As this is a survey experiment, the "intervention" involves random assignment to a survey questionnaire with specific wording. Each question in this version of the survey questionnaire permits the study participant to provide an open-ended numerical estimate.
