Study summary

This multi-centre research investigates the effects of nature-based treatment group on participants diagnosed with depression. In total, 147 persons participated in the study in various locations in Finland. All participants received treatment as usual (TAU). They were randomised into nature-based group + TAU (n = 70) or TAU-only (n = 77). The participants in the nature-based group + TAU were offered 12 sessions once a week in addition to standard care. The measurement points included pre-treatment measurement at the baseline and post-treatment measurement at the end of the intervention, which was 12 weeks after the pre-treatment measurement. The follow-up measurement was 3 months after the post-treatment measurement. The effects of the intervention were assessed with a clinical measure of depression (BDI-I) and with indicators of psychological distress (CORE-10), subjective well-being (SWEMWBS), work/study ability (WAI) and nature experiences (ROS, KOLU). The participants in the treatment group (nature-based group +TAU) were compared to the participants in the control group who received TAU-only.

Read the detailed description

This research investigates the outcomes of nature-based treatment groups in the treatment of adults with depression. In total, 147 participants were involved. Of them, 70 were randomized into DMT group and 77 into the control group. All participants received treatment as usual during the research. The inclusion criteria of the study were: a diagnoses of depression (ICD -diagnostic system), BDI-I score 10 or above (cut off score for mild depression), treatment contact in a health care service and 18-65 years of age. The exclusion criteria were: 1) active suicidal ideation, 2) psychotic symptoms, and 3) substance misuse that is on a critical level (Audit questionnaire scores above 10). Also, participants who had pain-related problems that restricted daily life or were pregnant were not admitted to the study.

Nature-based treatment group was facilitated by a health care professional and included 12 x 90 mins sessions within 12 weeks. Depressive symptoms (BDI-I), psychological distress (CORE-10), subjective well-being (SWEMWBS), ability to work/study (WAI), and nature experiences (ROS, KOLU) were assessed at three measurement points: pre-measurement at the baseline, post-measurement 12 weeks after the pre-treatment measurement, and a follow-up measurement three months after the post-treatment measurement.

This research includes a larger number of participants (N = 147) than have been involved in previous studies utilising randomised controlled trials in nature-based interventions. The research generates further information about the effectiveness of nature-based therapy groups in the rehabilitation of depression as it was conducted in five cities across Finland. This type of multi-centre research can provide a realistic picture of the typical practice of a range of health care professionals working with participants in various geographic locations.

What researchers measure

Primary outcomes

  1. Change from baseline depressive symptoms (Beck Depression Inventory; BDI-I) at 12-week post-treatment measurement.

    BDI-I (Beck Depression Inventory - I) measures depressive symptoms with 21 items. Each item is scored 0-3 and sum scores are calculated on the basis of participants' responses. The total sum score can range from 0 to 63 and higher score indicates higher depression.

    Time frame: 12 weeks

  2. Change from post-treatment depressive symptoms (Beck Depression Inventory-I; BDI-I) at three-month follow-up measurement.

    The change in depressive symptoms between the post-treatment measurement at the end of the 12-week intervention and the 3-month follow-up. BDI-I (Beck Depression Inventory - I) measures depressive symptoms with 21 items. Each item is scored 0-3 and sum scores are calculated on the basis of participants' responses. The total sum score can range from 0 to 63 and higher score indicates higher depression.

    Time frame: 3 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2019 to primary completion in Mar 2021, 26 months.

Of 3,468 non-industry interventional studies with no phase under Depression, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 41. This study's 26 months is above that.

Counting every sponsor, half of 3,566 studies reached it within 21 months; a quarter within 9 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 1, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
