Stoptober (Netherlands)

Dutch version of England's 28-day collective quit challenge, run each October since 2014 by the health charities KWF, Hartstichting and Longfonds with the Trimbos Institute: mass media before the start, then ambassadors, an app, social-media community and daily support during the month.

Evidence

ObservationalPositive

Troelstra, Harting & Kunst (2019): 2016 participant cohort, 6,856 at baseline and 1,127 (16.4%) at three months; 71.8% of responders reported having quit, which the authors adjust to about 50% for differential dropout; no comparison group. Tieks et al. (2018): interrupted time series of Google searches 2014-2016 found Stoptober weeks raised quit-related search volume by 11-22% in the Netherlands with no rise in Belgium (control). Troelstra et al. (2019) qualitative interviews (n=23): participants valued the social contagion and goal-setting but wanted more support after the 28 days. More than 50,000 participants a year per the evaluation.

Research notes

No agency credit found. Organisers fetched from stoptober.nl 2026-10-22; earlier partner lists in press (VWS ministry, GGD GHOR, Alliantie Nederland Rookvrij) are search-snippet only. The evaluation says pre-launch 'traditional and new mass media' were used; specific TV/radio buys not confirmed, so not tagged. 'celebrity' = the role-model ambassadors named in the evaluation (press says well-known Dutch people; snippet). England's Stoptober (2012-) has no case yet; 'related' should point to it if one is added. Related 113-zelfmoordpreventie is only for Dutch-country browsing; drop if unwanted.
