When self-management is not carried out effectively,symptoms and asthma attacks arise, leading patients to experience a decrease of quality of life,21 increased hospitalizations,22 unscheduled doctor’s and, emergency department’s visits, and the days lost of work/school.17 Due to the importance of asthma self-management, every patient should possess the skills to carry out activities and behaviours that lead him/her to an appropriate self-care. Judgment skills allow individuals to built knowledge collected from past experiences,and from other sources of information (e.g. doctors, internet, etc) and then use it according to the health situation encountered. For instance an asthma patient when experiencing symptoms while exercising could respond to the situation by using his medicine on time and stopping the activity. Such a response is partly a result of the appropriate use of health information built upon past experiences, evaluation of pros and cons of action taken, and communication with doctors, which are in sum judgment skills.
