First of these is a basic password. This expires every three months (timed to co-incide with doctor visits). The password is supplied by the doctor - no visit, no password. This ensures that the youngster complies with the scheduled number of doctor vists. A prompt is inbuilt into the system reminding the player of when the password is due to expire: "Don't forget to schedule your next doctor visit now, as your password expires in 10 days". The next level of access control features a quiz-type section. Each log-in throws up a question which needs to be successfully answered to enter the game. The answer to this question will be found in the asthma handbook. The third level is the peak flow chart. This must be complete and up to date in order for the player to access the game. This will be differently structured; the parent is required to input the peak flows using a different password. The reason for this is to involve the parent and place a control in the system.

Push - pull motivation

This creates a push-pull motivation. Parents are aware that they need to fill in the chart. They need to log-in with their own password (obviously not to be divulged to the child) and fill in the graph. Their responsibility for doing this ensures thay they check the youngster has measured the peak flow timeously and correctly. There is also a motivation for the child, who will pressure the parent to fill in the graph - if the parent hasn't filled it in, no games! Allied to this, we propose an automatic down-load of the graph to the caseworker. Once the graph is filled in, and the parent hits enter, the system automatically e-mails the chart to the care-worker handling the case. This provides a third level of control - if the care-worker has not received the charts, follow-up action is taken to determine why compliance is not being maintained.
