Evaluating a serious game to improve childhood cancer patients' treatment adherence.

Objective: Childhood cancer patients need to have good treatment adherence. Unfortunately, treatment non-adherence often occurs due to high side-effect burdens of treatment and the lack of knowledge of one's illness and treatment. Therefore, a serious game intervention based on the Protection Motivation Theory (PMT) was designed and developed to motivate childhood cancer patients to undergo treatment and to motivate them to undergo treatment, perform daily self-care and educate them about their illness.
