简要总结
This study aims to investigate environmental factors that influence people's responses to the Japanese practice of forest bathing in Vancouver, B.C. parks.
详细描述
The primary research aim is to investigate the relationship between biotic and abiotic factors in a sample of Vancouver, B.C. forested parks and specific health-related outcomes after forest bathing interventions. Forest bathing programs are a promising therapeutic method for enhancing heart rate and blood pressure functions and an effective psychological relaxation strategy. This study will investigate changes in autonomic nervous system activity and mood states after a 60-90 minute forest bathing program in four Vancouver, B.C. parks. Approximately 100 adult participants will be recruited for the study and participate in four sessions over one year. Physiological responses, pulse rate, systolic and diastolic blood pressure, and psychological indices will be measured before and after each session.
The health effects of forest-based interventions will vary due to environmental factors such as weather, temperature, humidity, light, and participants' psychological and physiological states. We are taking measurements pre- and post-treatment to detect any change in response during each session and seasonally.
Primary endpoint is to determine if the guided walk provides greater enhanced heart rate and blood pressure functions and an effective psychological relaxation strategy over the self-guided walk.
Secondary endpoints: 1) to determine if participants living in neighborhoods with below average street trees receive greater benefits than participants that live in neighborhoods with average or above average street trees, 2) assess changes within the same individuals over time 3) if there are different outcomes seasonally 4) if there are different outcomes between study sites.

结局指标
主要结局
Abbreviated Profile of Mood States (POMS) - Change
时间窗: Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.
Abbreviated Profile of Mood States (POMS) are routinely used by forest bathing researchers because psychologists regard it as rendering an accurate measure of mood states. The goal is to determine if spending time in a forest environment affects a psychological response. Abbreviated POMS contains 40 questions. Each answer is scored on a Likert Scale with values of 0, 1, 2, 3, and 4. Lower total scores indicated low mood problems, and conversely, a higher score may indicate a high mood problem. POMS will determine a baseline level of specific moods for a participant at the onset of the research trial and at the beginning and end of each forest bathing session.
Cardiovascular reactivity - Heart Rate - Change
时间窗: Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.
Cardiovascular reactivity will be measured by participants taking heart rate before and after each forest bathing session.. Three measurements will be taken at 30-second intervals. The mean of the final two measurements taken for each interval will be used for statistical analysis.
Cardiovascular reactivity - Blood Pressure (Diastolic) - Change
时间窗: Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.
Cardiovascular reactivity will be measured by participants taking diastolic blood pressure before and after each forest bathing session.. Three measurements will be taken at 30-second intervals. The mean of the final two measurements taken for each interval will be used for statistical analysis.
Cardiovascular reactivity - Blood Pressure (Systolic) - Change
时间窗: Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.
Cardiovascular reactivity will be measured by participants taking systolic blood pressure before and after each forest bathing session. Three measurements will be taken at 30-second intervals. The mean of the final two measurements taken for each interval will be used for statistical analysis.
次要结局
- Connectedness to Nature Scale (CNS) - Change(Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.)
- Satisfaction With Life Scale (SWLS) - Change(Participants are tested before and after each forest bathing session and invited to attend four sessions during the study. Assessments for each session are included until the study ends. Forest bathing sessions will be held in 2022.)
