A 10-week group time course worked no better than one-to-one therapy

No differenceThe short version

A 10-week group course helped people rate their time use no better than one-to-one help with timers and calendars.

The study

  1. 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.

  2. 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.

  3. 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.

  2. Helped

    One-to-one help suited to each person improved how well people said they plan more than the group course did.
