This repository is for the paper: **Mathur MB, Gould M, & Khazeni N (2016). Direct-to-consumer advertisements can paradoxically increase intentions to adopt lifestyle changes. *Frontiers in Psychology* 7:1533.** All documentation is in the "READ ME" file; here is an excerpt: These materials are designed to guide a naïve user through independent replication of this study. In chronological order, this repository contains: (1) files that import directly into Qualtrics to recover the live questionnaire (including embedded logic and randomization structures) and all other experimental materials; (2) raw, unmodified data files; (3) a thoroughly commented R script to create analysis-ready datasets from raw data (with each modification and subject exclusion made programmatically, rather than manually); (4) the analysis-ready dataset; and (5) scripts that reproduce each statistical analysis and plot in the paper, structured with clear connection to sections of the manuscript.
