ISAAC Phase Three Video Questionnaire

The ISAAC Phase Three protocol includes a video questionnaire on asthma symptoms which is strongly recommended for the 13-14 year age group. The video, developed by the Wellington Asthma Research Group in response to translation problems with written questionnaires, was designed to overcome the problems inherent in the administration of written questionnaires in different languages. The video questionnaire has been validated (1-5) for the purpose of this study.

The Wellington Asthma Research Group has kindly made the video questionnaire available on this website. An abbreviated version of the video (right) allows interested investigators to assess this valuable tool. Please note that this is not the full questionnaire and is unsuitable for any use in research.

The full version of the video is available on this website from the link below. The file 150 is megabytes in size so ensure your internet connection has sufficient capability before using this link.

Answer sheets and instructions for the use of the video can be found in the Phase Three Manual.
