Behavioural Surveillance Surveys - The Wisdom of Whores

A “take-all” approach is to be utilized
whereby all FSWs present at the “time-location”
will be interviewed. Interviewers are to spend
the same amount of time at each time location
cluster. The precise times and hours to spend
at each time location will be established via
the mapping exercise and will be submitted to
each Supervisor prior to the start of fieldwork.
Long Distance Truck Drivers
The sample sizes for this target group are
as follows:
Livingstone - 300
Chirundu - 300
Chipata - 300
These individuals will be contacted at their
respective points of trade. These will be
identified through the mapping exercise and
a “time-location” schedule similar to the one
designed for the FSWs will be developed.
Interviews will be done at the same times on
each occasion and for the same period of time.
These individuals will be contacted and
interviewed at various points according to
where they congregate such as truck stops,
bars, et cetera. A mapping exercise to identify
these different points will be carried out and
a “time-location” sampling frame similar to that
which will be developed for the FSWs, will be
established for the purpose.
A schedule of time-locations, number of
interviews to be completed and the times at
which interviews with each target group are to
be completed will be submitted to you prior
to the start of fieldwork. This will serve as
your primary control tool for the execution
of fieldwork. This will be finalized after a
thorough mapping exercise of the various
locations at which the target groups congregate
has been completed.
Editing Checks
Supervisors are required to check and have
interviewers edit the questionnaire once the
interview has been completed. Instructions
for editing the questionnaire appear below :
Questionnaire editing will be done by the
interviewer or supervisor. Some interviews
may have to be done in the absence of the
supervisor (in particular for the FSWs).
In these instances, the supervisor must arrange
to meet the interviewer within 12 -24 hours
after the interview has been completed in
order for him/her to carry out another level
of checking and editing. Interviewers will be
required to edit their questionnaires before
considering an interview complete.
