How long Psychological Well-Being studies take

Of 1,304 interventional studies with no phase under Psychological Well-Being, half reached primary completion within 16 months of starting, counting those still running.

Start to primary completionEvery sponsorIndustryNon-industry
Interventional, no phase16 mo7–34 · 1,304 studies8 mo5–19 · 43 studies17 mo7–34 · 1,261 studies
Observational30 mo13–155 · 158 studies—35 mo14–155 · 149 studies

Each figure is the month by which half the studies had reached primary completion, with the range in which the middle half did. Studies still running count until their last registry update; studies that stopped early are left out. Phase 1 includes early phase 1; observational means prospective or not stated, as retrospective and cross-sectional studies date a window of data rather than a study.
