1. Objectifs

Intentions :
The aim of the study «was to first identify the most appropriate theory-based BCTs [behaviour change techniques] for an intervention to promote the use of a PtDA [Patient decision aids] for DS [Down syndrome] prenatal screening, and then to explore pregnant women’s perceptions about the acceptability and relevance of these BCTs.» (p. 3)

Questions/Hypothèses :
The authors propose «that the resulting intervention may improve pregnant women’s intention to adopt these tools for DS screening, and, potentially, their decisional and health outcomes.» (p. 3)

2. Méthode

Échantillon/Matériau :
L’échantillon est composé de 15 femmes enceintes de plus de 16 semaines, ou ayant récemment accouché, qui ont participé à des «focus groups». Les participantes ont été recrutées auprès de trois établissements situés dans la ville de Québec, soit auprès d’un département hospitalier d’obstétrique et de gynécologie, d’une clinique de médecine familiale ou d’une maison des naissances.

Instruments :
- Guide d’entretien semi-directif
- Grille d’observation

3. Résumé

«First, [the study shows that] the BCTs derived directly from the TDF [Theoretical Domains Framework] process were replicated through the BCW [Behaviour Change Wheel] process. This implies that the BCW may be comprehensive enough to be able to dispense with the TDF option […].» (p. 12) «Second, participating women found that 10 theory-derived BCTs were acceptable and relevant for use in an intervention to promote the use of a PtDA by women facing prenatal screening decisions. […] Third, participants proposed that a motivating factor for all pregnant women would be planned follow-up, which fits with the BCT “action planning”. […] Women in [this] study did not see the need for tailored strategies, except for demonstrating the PtDA for women with special needs. [Fourth, the analysis confirms that] “problem solving” (which includes “coping planning”) and “action planning”, are strategies usually used to support implementation, i.e. to move from intention to behaviour. [Lastly, the final] list only included 10 out of the 25 original BCTs, reducing the complexity of a potential intervention. [In this] study, many of the BCTs retained by the women necessarily involved the healthcare professional, for example, an action plan, and practical social support. This suggests that the most appropriate intervention would be an intervention plan in the clinical pathway of pregnant women that is implemented by the healthcare professional.» (p. 12-13)
