About

The investigators intend to evaluate patients aged 18 to 99 years with symptoms of anxiety and/or mild depression. A randomized controlled clinical trial will be carried out to evaluate the impact of the guided practice of forest bathing.

Full description

The practice of Shinrin-Yoku, also known as Forest Bathing, is an outdoor therapeutic modality with growing evidence suggesting positive effects on the psychological well-being and general health of individuals. However, its benefits have been studied mainly in Asian countries, needing further research to assess whether its benefits are also generalizable to other European-Mediterranean regions. To explore this question, the investigators intend to evaluate patients aged 18 to 99 years with symptoms of anxiety and/or mild depression. A randomized controlled clinical trial will be carried out to evaluate the impact of the guided practice of forest bathing. The participants will be randomly distributed in two arms, with a crossover design: arm A intervention + control; arm B control + intervention. Participation in this study consists of the execution of two sessions of guided forest bathing practice, and the completion of online evaluation forms before and after each session of guided forest bathing practice, for 24 hours afterwards, as well as before and after the program as a whole. The study includes clinical assessments, emotional well-being, social support and other complementary indicators. For hypothesis testing, a linear model of univariate analysis of variance intrasubject design will be applied to the dependent variables, with three phase conditions (pre, post and follow-up) and two treatment conditions (intervention vs. control).

50 participants in 2 patient groups

Forest Bath Intervention group A

Experimental group

Description:

The intervention consists of 2 sessions of approximately 2 hours duration and fortnightly frequency. In this context, it is guaranteed that patients will receive the care, visits and treatments usually used in people who have presented their clinical situation. The only difference between participating or not in the intervention is the participation in the practice of forest baths and the performance of some additional assessments, i.e. not routinely performed, which are part of this project. The investigators will be responsible for providing an overview of the study to eligible patients interested in participating. Before proceeding to start the intervention, an informed consent will be given to the patients, in which a description of the characteristics of the sessions will be provided.
