Procedure
Each questionnaire sent to the participants was accompanied by a letter explaining the
purpose of the study, the way to answer the items, and a statement of assurance that
the responses of the participants would remain confidential should they agree to
participate. Each respondent was requested to complete the questionnaire without
identifying him/herself and return it in a closed envelope. Due to the difficulties in
communication and transportation, the process required nearly six weeks to complete.
Some questionnaires had to be returned by fax, but the majority was collected
personally.
