Using Cueing Interventions to Promote Breastfeeding

Status Completed

Clinical Trial Summary

Background: Interventions focusing on promoting good behavioural intentions were found to only have small-to-moderate effect sizes on changing the actual behaviours. Self-regulation plays an important role to maintain individual attentions to the distant benefits of healthy behaviours and resist to proximal tempting cues from unhealthy behaviours, and thereby facilitate the translation of good intention into actual behaviours. However, self-regulation resources are limited and can be depleted in certain contexts. Providing environmental cues relevant to the desirable behaviours can activate the nonconscious process and lead to behavioural change without conscious awareness, the underlying mechanism of cueing interventions. Aims: To test the effectiveness of using two types of cues, social normative and goal-related cues, to activate the nonconscious process for facilitating the translation of intentions into actual behaviours. We hypothesize that (1) cueing interventions will be more effective than will conventional education-based interventions (providing factual information about health benefits) be for changing behaviours; (2) cueing interventions are more effective for participants who have a tendency to use an intuitive mode in information processing; and (3) goal priming is more effective for participants with stronger motivation to pursue the goal of sustaining breastfeeding. Subject and study design: The hypotheses will be tested in the behavioural context of breastfeeding among first-time mothers because: first, primiparous women may have less self-regulation resources due to high cognitive demand for postpartum adjustment during motherhood transition; and second, while breastfeeding intention and initiation were high, maintaining breastfeeding for the first six months postpartum was generally low in Hong Kong, indicating a substantial intention-behaviour gap. We propose to recruit 600 primiparous women. Baseline assessments will be conducted face-to-face using a standardized questionnaire. Participants will be randomly allocated to the control group (receive education-based messages about the health benefit of breastfeeding) or one of the two intervention groups (receive either social normative cues or goal-related cues related to breastfeeding). All messages will be delivered through smartphone on a daily basis over 16 weeks postpartum.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
