Study Arms (3)

Experimental: V1: Binary Response Options

EXPERIMENTAL

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.

Other: Survey questionnaire

Experimental: V2: Categorical Response Options

EXPERIMENTAL

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

Other: Survey questionnaire

Experimental: V3: Open-Ended Numerical Estimate

EXPERIMENTAL

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.

Other: Survey questionnaire

Interventions

Survey questionnaire 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.
