Plain English Summary

Background and study aims
Depression affects a large number of people in the United Kingdom and in other countries. Many experience it more than once and some suffer from long-standing depression. Established therapies offered within primary care include especially psychological and psychotherapeutic treatment, and antidepressant drugs. These treatments may help many patients, but the effect is sometimes insufficient. Also, some patients do not want to use existing treatment such as antidepressant drugs. There may be many reasons for this, such as previously experienced side-effects. Some patients choose to consult with a homeopath. There is however insufficient research evidence to draw any final conclusions for such treatment for depressed patients.

Who can participate?
Participants will be selected among those who have already agreed to participate in the South Yorkshire Cohort (SYC). They have been recruited through their general practitioners. Participants will be aged 18 to 85, and of both genders. Those included will have self-reported significant depression symptoms.

What does the study involve?
Participants are randomly allocated to Individualised treatment provided by homeopaths in addition to usual care, or usual care alone. All participants are sent a questionnaire at 6 and 12 months. Results for these two groups are compared. Some participants are also invited for an interview with a researcher in order to learn from their experience with treatment.

What are the possible benefits and risks of participating?
Those randomly selected for free treatment provided by a homeopath are offered a first consultation which includes the prescription of a homeopathic remedy, and follow-up treatment for up to 9 months. Previous researchers have found that mild or moderate temporary side-effects may be experienced by some after taking homeopathic remedies, but no serious side-effects are expected. Treatment is individualised to suit each patient. This includes the length and frequency of consultations, and the type of homeopathic remedy prescribed for each patient. Homeopaths may also offer other advice, such as to consult with a counsellor or a healthcare practitioner, or to use other supportive treatment. All included participants, whether offered treatment by a homeopath or not, may continue with other treatment as usual. All those who are taking conventional drugs must continue treatment as prescribed by their doctor.

Where is the study run from?
University of Sheffield (UK)
