Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Participants Outcome Assessors

Study participants are randomly assigned to be read survey questions with slight changes in the wording of the response options. Neither study participants nor outcomes assessors are provided with information about "treatment" assignment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental: V1: Binary Response Options

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.

Group Type EXPERIMENTAL

Survey questionnaire

Intervention Type OTHER

Each version of the questionnaire has the same questions about perceived norms about substance use in the community but differs in how the response options are offered.

Experimental: V2: Categorical Response Options

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

Group Type EXPERIMENTAL

Survey questionnaire

Intervention Type OTHER

Each version of the questionnaire has the same questions about perceived norms about substance use in the community but differs in how the response options are offered.

Experimental: V3: Open-Ended Numerical Estimate

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.

Group Type EXPERIMENTAL

Intervention Type OTHER

Each version of the questionnaire has the same questions about perceived norms about substance use in the community but differs in how the response options are offered.
