| Our questionnaire was based on detailed questionnaires tested in England and Denmark. |
| Copies of the two questionnaires and answer sheets were included with the letter to staff. |
| Pupils placed completed questionnaires, identified by study number only, in sealed envelopes. |
| They will be asked to fill out questionnaires documenting details of their family history. |
| The detailed content of each section was tailored according to the answers in individual questionnaires. |
| The class then turned its attention to putting together sample questionnaires for the survey. |
