This questionnaire intends to find out more about your behavior within online health and social support communities. Health communities include those that have been specifically set up to provide support (health and social support and information) around specific health concerns, conditions and illnesses (including physical and mental health conditions and other types of disability). This also includes people who are providing support and care and online communities specifically for those groups. Communication within these groups can take place through forums, message boards and chat facilities. In particular, we are interested to find out the reasons why people do and do not contribute to such communities. Focussing on the health condition that you most regularly seek support/ information for, please read through the following questions and answer them as quickly and as honestly as you can.
