A number of non-medical professionals can provide help for depression. These include psychologists, mental health social workers, counsellors and mental health nurses. They typically provide talk therapy such as cognitive behaviour therapy or interpersonal therapy.
Look for therapists who are registered by government or professional bodies. This means that they are qualified practitioners. They must also work within strict codes of conduct. Most registration bodies also require the therapist to keep their knowledge and skills up to date.
Each professional group has its own standards for registration. These vary from country to country.
In Australia, rebates may be available through Medicare or private health funds and you can find out more from your General Practitioner or by visiting the Australian Department of Health website.
