The purpose of the study was explained during these sessions and the nurses present were invited to join in the study. The questionnaire was handed to them directly and they answered it during the time allocated for this purpose. However, at setting B the author made two visits a week over 3 months to distribute and collect the questionnaires. Questionnaires were given directly to the nurses present on those same days. During these visits, the nurses were able to answer the questionnaire right away and return it to the researcher or, if they wished to respond later on, an envelope was left on site so they could drop off the questionnaires. In addition, posters promoting the study were put up in the in-home support unit offices.
