Baseline life satisfaction: day-365 completers 5.92 (n=368) vs. non-completers 5.90 (n=272). Dropout is not random (decliners leave more often in this dataset), so later-wave means may be biased upward.

Reading these results

  • This is an observational cohort without a comparison group. Changes over time may reflect regression to the mean, life events, seasonal effects, expectation, or who stays in the study — not programme effects.
  • Respondents self-select into both the programme and the study.
  • Wave means are unadjusted. Planned analyses use mixed-effects models with sensitivity analyses for missing data.
  • Journey exploratory items have not been validated.
