The effect of a single visit to a health coach on perceived health in 50-year old residents in a high-income country - a randomised controlled trial.

OBJECTIVE

To evaluate the one-year-effect of a single visit to a health coach on perceived health and exercise level in 50-year-old citizens.

DESIGN

One factor design randomised controlled trial.

SETTING

Participants were randomly selected from the Swedish Population Register.

SUBJECTS

50-year-old residents of the town of Alingsås, Sweden ( = 105).

INTERVENTION

The intervention group ( = 52) received a single one-hour visit to a health coach. The control group ( = 53) received no intervention.

MAIN OUTCOME MEASURES

Change over 12 months in the SF-36 dimensions physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, physical component summary and mental component summary. Reported health transition at follow-up. Change in exercise level.

RESULTS

The control group changed their perceived health more favourable than the intervention group in the following dimensions of the SF-36; general health ( = 0.0055-0.025), role-emotional ( = 0.034-0.040) and mental component summary ( = 0.033-0.073).

CONCLUSION

A single visit to a health coach does not improve perceived health or exercise-level in 50-year-old citizens. On the contrary it may make perceived health worse.Key pointsResearch on health coaching has emerged in the last 20 years, but is diverse and the characteristics of a successful health coaching intervention are still unknown.There is a lack of randomised controlled trials evaluating long-term effectiveness of health coaching.This randomised controlled trial concludes that a single visit to a health coach does not improve, but rather impairs, perceived health in 50-year olds.
