The endpoint was statistically successful, but the effect was small and complete 4.5-month stress data existed for only 1,123/2,182 participants (51.5%).
ads claimA 'twice the improvement' framing obscures absolute size. Baseline reductions were about 2.42 points with Headspace and 1.03 with Moodzone, but the 4.5-month between-arm difference was 2.00 points on a 42-point scale with g=0.26.

What the research actually shows
ISRCTN15424185 was prospectively registered on February 17, 2017 and designated 125-day DASS-21 Stress as primary. Headspace received 1,095 assignments and Moodzone 1,087. Complete 4.5-month stress data were available for 571 and 552, totaling 1,123, while multiple imputation included all 2,182. The 4.5-month between-arm difference was 2.00 points (SE 0.42), g=0.26. Among complete-data respondents, formal Headspace use averaged 3.56 days per week initially and fell to 2.16 days per week later. ESRC and Headspace jointly funded the work, and Headspace studentship, research, and consultancy relationships were disclosed.

Counterpoint. Burnout and sickness absence did not improve. A small stress-score difference cannot replace organizational workplace changes.
Rejudgment record. Cross-check applied — Credited prospective registration, primary-endpoint success, and an active control while accounting for g 0.26, 48.5% missing complete data, self-report, and Headspace cofunding
