    • 14.1: Introduction to questionnaires
    • 14.2: The questions
      Quantitative data may be collected in field trials by a series of questions asked of the respondents that are compiled into a questionnaire. Additional quantitative data may be obtained by direct observation (for example, of what the house’s roof is made of or of whether a male has been circumcised), measurement (for example, weight), or after taking a tissue sample (for example, haemoglobin level). This section will cover issues related to data that are collected through questions.
    • 14.3: The questionnaire
      Adequate time must be allowed for the interviewer to solicit the correct responses to all the questions included in a questionnaire.
    • 14.4: The interviewers
      Interviewers should be selected with careful attention to the tasks they will be expected to perform. They must be seen by the respondents as individuals who can be trusted to keep sensitive and confidential information to themselves. They must be of pleasant disposition, and be well-mannered, well-dressed, reliable, and punctual. They must not make promises to respondents that they do not honour (for example, if they say they will return on a given day they must do so or, at least, send a messa
    • 14.5: Data capture
      Traditionally, data, whether from interviewer-administered or self-completion questionnaires, have been entered initially (captured) on to paper, but there is increasing use of electronic data capture. The latter has many advantages and has become more generally feasible, as the sizes, prices, and robustness of suitable electronic devices have improved.
    • 14.6: The interview
      As much as possible, a face-to-face interview should approximate to a conversation between the interviewer and respondent and must not be an interrogation. Good rapport between the two is vital, and the onus is entirely on the project team to ensure this.
