An online psycho-therapeutic approach that teaches people to change how they think about and respond to situations so that they feel and act better, even if the situations haven't changed. It works by helping people make sense of overwhelming problems through breaking the issues down into smaller pieces, which in turn makes it easier to see how the pieces are connected and how they affect people's emotions. Instead of giving the care in person, online cognitive behavioural therapy renders the service over the internet.

A recent study found that teens with chronic fatigue syndrome who received six months of online behavioural therapy were far more likely to recover than those given care in person.
