Background and Intervention
: Health professionals are key in supporting breastfeeding women but studies report gaps in health professionals’ breastfeeding support competencies. In an intervention study, we aimed to strengthen the breastfeeding support of families to improve breastfeeding rates. Health visitors received an interactive training programme to enhance their breastfeeding support self-efficacy, action competence and knowledge, including e-learning and a two-day course of lectures, role plays, and discussions.
Objectives
To assess the effect of the training programme on three constructs of health visitors’ breastfeeding support: self-efficacy, action competence and knowledge. Furthermore, we aimed to confirm the factor structure of these three constructs.
Design and Methods
: Pre- and post-test study in a cluster randomised trial with Danish municipal health visiting programmes as cluster units, randomised by stratifying for region and annual births per cluster. Health visitors from 21 clusters (11 intervention, 10 control) participated. The self-efficacy, action competence and knowledge were assessed in self-reported questionnaires before and after training (n = 368; intervention n = 176, control n = 196). To analyse the effects, the intention-to-treat principle and linear mixed models were applied. Confirmatory Factor Analysis was used to confirm the factor structures of the hypothesised self-efficacy, action competence and knowledge constructs.
Results
158 health visitors in the control arm and 157 in the intervention arm completed the baseline questionnaire and were analysed in intention-to-treat analyses. 125 and 116, respectively, completed the follow-up questionnaire and were analysed in sensitivity analyses. Health visitors in both trial arms had high levels of self-efficacy and action competence at baseline. Mean treatment effect of the training programme was 2.4 points (CI95% 1.6–3.3) for self-efficacy, 1.4 points (CI95% 0.7-2.0) for action competence, and 0.5 points (CI95% 0.1–0.8) for knowledge. The factor structure of the items used to measure self-efficacy, action competence and knowledge were confirmed.
Conclusions
The training programme improved the self-reported breastfeeding support self-efficacy, action competence and knowledge of health visitors. The factor structures of the instruments used to measure effects were confirmed by confirmatory factor analysis.
