Plain English Summary

Background and study aims
Major depressive disorder, commonly referred to as depression, is a widespread and burdensome condition. It is associated with the second greatest number of life years lost due to premature death or disability and will most likely be the leading cause in 2030. Physical activity has proven to be an effective treatment as a complement to drugs and psychotherapy. However, people suffering from major depressive disorders are particularly vulnerable to physical inactivity and lack of physical activity maintenance because of other disorders and problems with motivation. Therefore, physical activity counselling may have the potential to increase lifestyle physical activity and cardiorespiratory fitness in this population, thus not only tackling mental but also physical health problems. The aim of the present study is to compare two types of physical activity interventions to increase physical activity in people with major depressive disorder.

Who can participate?
People aged 18-65 who have depression, can speak and read German and do not currently participate in physical activity may participate in this study. Additionally, inactive, German-speaking women and men, aged 18-65, without a current or previous diagnosis of major depression may take part as a group to be compared with the group of patients

What does the study involve?
Hospitalised participants will be randomly assigned to one of two groups - the intervention group or the control group. The intervention group will receive individually tailored physical activity counseling, which includes three face-to-face meetings, and continuous remote counseling upon leaving the clinic. The control group, the group which is to be compared to the intervention group, will receive written information regarding a healthy lifestyle along with one face-to-face meeting in which the written information will be discussed and further emphasised with a short animated film. All hospitalised patients will continue receiving the standard medical and psychiatric care. Additionally, the initial measurements taken from the hospitalised patients will be compared to healthy peers, who will not be receiving any treatment. Measurements of physical activity will be taken upon hospitalisation, six weeks after hospitalisation, and 12 months after the end of hospitalisation. Measurements from the healthy counterparts will be taken once.

What are the possible benefits and risks of participating?
The possible benefit of taking part is that participants will receive their personal health profile including insight into their cardiovascular risk factors, fitness and activity levels as well as sleep quality. Ultimately, participating in the study may lead to increases in physical activity, which in turn may effect long-term response and remission rates in patients with major depression. This does not only secure a personal benefit but it also benefits people suffering from the same disorder. There are no known specific risks of participating.

Where is the study run from?
Department of Sport, Exercise and Health of the University of Basel, Switzerland and four Swiss clinics specialised in psychiatric care

When is the study starting and how long is it expected to run for?

Scientific title

Lifestyle Physical Activity Counselling for IN-PATients with major depressive disorder: Randomized controlled trial on physical activity, cardiorespiratory fitness, depression, and cardiovascular health risk markers



Study hypothesis

Compared to treatment as usual, individually-tailored physical activity counselling in patients with major depressive disorders will lead to clinically relevant increases in physical activity and cardiorespiratory fitness, and these outcomes will persist beyond clinical discharge.

Patients will be randomly assigned (stratified by age, gender, and depression severity) to an extended personalised physical activity and exercise counselling program (intervention group) or to general instructions about health-enhancing physical activity (placebo control group). To ensure allocation concealment, allocation to groups will be done by a computer-generated code after the baseline assessment has taken place. To minimise subjective biases, patients do not know whether they have been allocated to the intervention or placebo control group. Before providing informed consent, patients will be informed that the goal of the study is to test different methods to promote a more physically active lifestyle among patients with major depressive disorders who do not meet levels of physical activity recommended by the American College of Sports Medicine. Clinicians, researchers, and physical activity facilitators will not be blinded to treatment allocation because of the nature of the study. However, outcomes will be assessed by researchers who do not know whether a patient belongs to the intervention or placebo control group.
Patients assigned to the intervention group will receive 12 months of individually tailored physical activity counselling to provide support and encouragement to increase physical activity during and after clinical treatment. This intervention is based on a standardised, theory-based, short, low cost lifestyle physical activity counselling program, which was specifically designed for an in-patient rehabilitation setting. It consists of three face-to-face meetings in which tailored exercise prescriptions and behavioural change techniques will be delivered. The exercise prescriptions follow the standards of the American College of Sports Medicine and behavioural change techniques include motivational and volitional strategies to promote and foster long-term behavioural change. Additionally, after hospitalisation, remote meetings will continue until 12 months after discharge, whereby three methods of administration will feature bi-weekly telephone counselling, SMS prompts, and smartphone app notifications.
Patients assigned to the placebo control group will receive written information about health-enhancing physical activity based on the “Core document for Switzerland” published by the Federal Office of Sport in collaboration with other institutions. Additionally, the patients will receive written and oral standard recommendations regarding exercise and physical activity in the treatment of depression. Before the end of the in-patient treatment patients will have a face-to-face meeting in which the key contents of the “core document” will be discussed supported by a short animation film.

Intervention type



Drug names

Primary outcome measure

1. Objective physical activity, assessed using an Actigraph accelerometer for a seven day period with a sampling epoch of 10 seconds. Time spent in moderate physical activity and vigorous physical activity will be determined based on the accelerometer counts and the ActiLife® computer software. Only days with at least 13 hours of wear time will be considered as a valid measure of daily activity. Participants will need at least five valid days, ≥ 4 weekdays and ≥ 1 a weekend day, for the data to be included in the data analyses. This will be assessed at the baseline (1-2 weeks after hospitalisation), 6 weeks after hospitalisation and at the follow-up (12 months after hospitalisation)
2. Physical activities during which the accelerometer cannot be worn (i.e. swimming), assessed using a non-wear time sheet

Secondary outcome measures

The following will be assessed at the baseline (1-2 weeks after hospitalisation), 6 weeks after hospitalisation and at the follow-up (12 months after hospitalisation):
