Households in Ottawa, Canada, were mailed postcards with a checklist that framed testing for radon as a routine action to check air quality and keep a healthy home. The postcards also included a vendor website link where people could buy a test kit online. A control group did not receive a postcard.<\/p>\n\n\n\n<p>More test kits were purchased by the households who received a postcard, but take-up was low &ndash; only seven tests were purchased in the treated groups and one test in the control group. These results suggest that this form of &lsquo;nudge&rsquo; was not necessarily a cost-effective strategy to elicit a purchase.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Key points for decision-makers<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Radon is present in all homes. It is an invisible, odourless, and tasteless gas so the only way to know exposure levels is to test for it.<\/li><li>Public demand for tests is deemed too low &ndash; Statistics Canada found that 7% of Canadian homes were tested for radon in 2017 and 3% in 2009.<\/li><li>The authors used a cluster randomised control trial with 15,043 households across 22 postal route groups in Ottawa, using postcards as a method to nudge recipients to purchase a radon test.<\/li><li>The study was conducted in partnership with Health Canada&rsquo;s National Radon Program.<\/li><li>The authors used two variations of the postcard. The postcard in treatment A directed people to a vendor website where a test could be directly purchased with one click. In treatment B, people were directed to a product aggregator website, currently recommended by Health Canada, which offers more product choice, health risk information and at least four clicks to purchase a test. So a secondary aim was to explore if testing could be increased by making the online purchasing experience easier.<\/li><li>The authors found that the nudge increased test purchases, but the low-take up &ndash; seven tests in the combined treated groups versus one in the control &ndash; suggests this nudge is not a cost-effective strategy in isolation.<\/li><li>Directing people to a website with more information, more product choice and more clicks to purchase (treatment B) was not less effective, suggesting that more &lsquo;friction&rsquo; on the purchase website did not deter purchases in this context.<\/li><li>Based on the results of this trial, the average cost (from printing and mailing) to Health Canada for encouraging a household to purchase a radon test kit was CA$416.41. The cost of a radon testing kit purchased online typically ranges from CA$30 to $60.<\/li><li>That said, there may have been additional benefits from this study, like increased awareness and radon risk perception, which the authors cannot measure.<\/li><\/ul>\n\n","protected":false},"excerpt":{"rendered":"<!DOCTYPE html PUBLIC \"-\/\/W3C\/\/DTD HTML 4.0 Transitional\/\/EN\" \"http:\/\/www.w3.org\/TR\/REC-html40\/loose.dtd\">\n<?xml encoding=\"UTF-8\"><p>The authors of this paper examined if a &lsquo;healthy home checklist&rsquo; would nudge households to purchase a test for radon &ndash; the leading cause of lung cancer after smoking &ndash; online, and found the strategy to increase take-up but to a low extent. <\/p>\n\n","protected":false},"author":23,"featured_media":52506,"template":"","tags":[2004,970,713,1881,2003],"publication-type":[435],"topic_area":[4698],"class_list":["post-52422","publication","type-publication","status-publish","has-post-thumbnail","hentry","tag-air-quality","tag-canada","tag-consumer-behaviour","tag-nudge","tag-radon","publication-type-working-papers","topic_area-behavioural-responses"],"acf":{"exclude_from_sync":{"ref_value":"field_560538b0e7350","value":"1","type":false,"post_type":""},"downloads":{"ref_value":"field_52f16cc1a80f2","value":["https:\/\/www.lse.ac.uk\/granthaminstitute\/wp-content\/uploads\/2020\/09\/working-paper-347-Howe-Shreedhar.pdf"],"type":"download","post_type":""},"rss_newsletter":{"ref_value":"field_54f5c2c1544d8","value":"","type":false,"post_type":""},"profile_link":{"ref_value":"field_52f164b5189e9","value":["jane-howe","ganga-shreedhar"],"type":"relationship","post_type":"profile"},"spotlight":{"ref_value":"field_52f80896506d3","value":"","type":false,"post_type":""}},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Do healthy home checklists nudge people to test their home for radon?
