National cross-sectional survey of US adults to assess the reliability of current and lifetime cannabis smoking.

ABSTRACT:

Objective

The objective is to examine the test-retest reliability and internal reliability of six self-report questions assessing both current (past 30 days) and lifetime cannabis smoking in an internet survey in the adult US population.

Design

Cross-sectional national survey.

Participants

Out of 957 US adults who completed a national 2020 survey administered through Ipsos KnowledgePanel, 557 completed a second survey ('reliability survey') aimed at assessing the test-retest and internal reliability of questions asking about current and lifetime cannabis smoking. The sample size used in the analysis for the six self-report questions varied and was dependent on respondents answering the questions in both the 2020 survey and the reliability survey.
