The Active Permanent Workshop of Imputologists (APWI) was created in 1981. Its concern is to facilitate better understanding among all those interested in developing better assessment of causality. An international secretariat was organized, a newsletter is now published, and a comparative study of different methods of assessment is planned. A questionnaire to get an insight into member needs, etc., revealed that 60 respondents (out of 87 answers received) use one or another method to assess causality.
