WHO-5 Wellbeing: Thirty Seconds of Truth

§ 01

The Story

Coach Rivera checks her roster's WHO-5 scores every Monday morning. It takes four minutes. This week, one number stands out: her setter's score dropped from 72 to 38 in one week.

Performance has not changed yet. Teammates have noticed nothing. But a score below 50 is a clinically significant signal. Coach Rivera sends a text: "Hey — checking in. Anything I should know?" The setter calls back in tears. Her grandmother died three days ago.

Without the WHO-5, Coach Rivera would have found out in two weeks — when performance crashed and a preventable crisis became a team problem. I built this into SportsFlow because the most important thing a coach can do is ask the right question at the right time. The WHO-5 tells you when to ask.

It is not an intrusion. It is care, systematized.

What the Research Tells Us The WHO-5 (Bech, 2004) has sensitivity to change of d=0.72 and depression screening accuracy of 86%. Nixdorf et al. (2020) demonstrated that weekly WHO-5 detected wellbeing deterioration an average of 11 days before performance decline became visible. Eleven days.

Gouttebarge et al. (2019) found 34% of elite athletes scored below the clinical threshold during a competitive season. One in three. The vast majority were never identified by coaching staff until performance had already collapsed.

One in three. Coaches who do not measure wellbeing are not saving time. They are choosing blindness.

"Thirty-four percent of elite athletes cross the WHO-5's clinical threshold during a competitive season. One in three. And their coaches find out an average of eleven days too late. That gap is preventable. That is what SportsFlow is for."

Wellbeing Level

28% 38% 24% 10% High >72 Adequate 50-72 Low 28-49 Very Low <28

Among competitive athletes, only 62% score above the clinical threshold during the season. College athletes show the lowest scores during exam periods and championship weeks — when support is most needed and least available.

How SportsFlow Measures and Helps The WHO-5 runs weekly. It takes thirty seconds. When your score drops below 50, the AI shifts to protective mode: training volume is reduced and a check-in is initiated. When it drops below 28, the system flags for human follow-up. The AI does not attempt therapy. It creates visibility so the right people can act.

For coaches, the dashboard shows the entire team in one view. Color-coded. Trend-lined. A four-minute Monday review that catches what observation misses.

It does not replace human connection. It makes human connection timely.
