Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2017 (actual). Primary completion is estimated for Jul 2020, 33 months after the start.

Of 149 non-industry observational studies under Psychological Well-Being, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 155. This study's planned 33 months is close to that.

Counting every sponsor, half of 158 studies reached it within 30 months; a quarter within 13 and three quarters within 155.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 9, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
