The study
Who took part
75 adults in Sweden, aged 19 to 61 and about 32 on average, who said they struggled to manage their time. Most had ADHD or autism; others had a mood disorder or were waiting for a diagnosis.
What they did
One group was offered 10 weekly group sessions of up to 2 hours each. They learned about calendars, energy, sleep and wake rhythm, and how long tasks take. People went to about 6. The other group got their usual one-to-one sessions with a therapist, about 6 on average. Most got timers and calendars, help to use them, and facts about their diagnosis.
What happened
Both groups rated their time management better at the end and three months later, with no clear difference between them. The one-to-one group rated their planning and their handling of feelings better than the course group did. Many people dropped out, mostly from the group course.
