Community midwives work autonomously in private practices and take care of low-risk births at home or in the hospital. Clinical midwives working in hospitals are supervised by gynaecologists. Their professional association provided the addresses of 525 community midwife practices and 317 clinical midwives. Each received a request to complete the questionnaire, either online or in print. Midwives in private practices were asked to appoint one affiliated midwife to complete the questionnaire. No reminders were needed as enough respondents replied in the given time.
We selected university and general hospitals, evenly distributed among the 91 Dutch hospitals in 2012 (Panteia/EIM 2013) to participate. We asked their managers of paediatric wards and neonatal intensive care units to e-mail invitations with a link to our online questionnaire to all their nurses who work with children aged 0–6 months. Twenty of the 21 hospitals we approached agreed to participate. Approximately 900 nurses were invited. The managers were asked to send reminders after 3 weeks.
We used the predictive analytic computer software SPSS (Statistical Product and Service Solutions, IBM, New York, version 22) to process and analyse the data. No items were missing in the completed online questionnaires since this was required for completion. We excluded unfinished paper questionnaires from the analysis. Incomplete items were entered as “missing”.
Data analysis
First, we descriptively analysed the personal and psychosocial measures (frequencies). We dichotomized determinants (≥ 5.0 was positive; < 5.0 was negative) for descriptive purposes, where relevant. Those measures for which more than 90% of the respondents gave the same answer were excluded from further analysis because of low variability. Since the intention data showed a non-normal distribution for each group, we dichotomized the intention measure (≥ 5.0 for intention, < 5.0 for no intention) for further
