Twenty-seven (50%) of the 54 delivered questionnaires were returned.
We delivered questionnaires to all participating mothers under examination conditions overseen by trained LHA program research staff.
At baseline, research assistants delivered questionnaires (demographic, depression, sleep quality, sleep cognitions, and fatigue measures), actigraphs, and study-designed sleep diaries to families.
The project nurse obtained consent, delivered questionnaires and the education and training modules (3 visits), assisted with equipment and process inventories (Table 2), extracted data (3 visits) and offered advice.
The lack of anonymity with verbally delivered questionnaires might encourage socially desirable responding, but use of neutral market researchers may reduce this effect, compared to, for example, a member of the study research team.
A web-site delivered questionnaire is e-mailed to the participants at baseline, week 12, and at 6, 12 and 24 months.
A surface mail delivered questionnaire was expected to reduce such bias, provide anonymity, and not be tainted with direct connection to the care provider.
All of the respondents received two copies due to the fact that researchers could not identify the sample population after delivering the questionnaires for follow-up.
However, as a consequence of our sampling strategy, which entailed delivering the questionnaires to the participants via the workplace in specific municipalities, only participants who remained employed in the municipalities received the follow-up questionnaire.
