Common mental disorders such as anxiety, depression and stress-related disorders are increasing worldwide, resulting in long-term sick leave and lower quality of life. Traditional treatment is often insufficient to facilitate the recovery process, and the need for holistic interventions that enable successful recovery is evident. Equine-assisted interventions have shown promising results in health promotion among people with mental disorders, and further research is needed to implement them within the range of available care. The aim of the study is therefore to describe experiences of a therapeutic equine-assisted group intervention for people with common mental disorders on sick leave. The study has a descriptive qualitative design with an inductive approach. Ten participants with common mental disorders on sick leave were interviewed after participating in a 12-week equine-assisted intervention and the data were analysed with conventional content analysis. The analysis generated the overall theme "The equine-assisted group intervention facilitates recovery," which summons the four categories "The environment of the horses contributes to relaxation and an ability to be in the present," "The presence of the horses facilitates supportive relationships in the group," "Interplay with the horses entails physical activity and bodily improvements" and "Emotional interactions with the horses strengthen inner power." In conclusion, equine-assisted interventions have the potential to facilitate recovery for people with common mental disorders by providing relaxation, promoting the ability to be in the present, cultivating supportive relationships and providing physical activity and bodily improvements as well as emotional interactions that strengthen the participants' inner power.
