Intention to Engage in Alcohol Use during Pregnancy: The Role of Attitudes and Prototypes.

Background: There is no known risk-free level of alcohol use in pregnancy. Despite this, many still believe that occasional drinking is safe. To-date, there is limited evidence of the influences on women's decisions about low to moderate alcohol use in pregnancy. The aim of this study was to explore alcohol use intentions during pregnancy, using variables from the theory of planned behavior, the prototype/willingness model and personality variables. The study also investigated whether priming participants with exposure to prototypes describing different alcohol use behaviors had an impact on intentions.Methods: Participants, 746 women aged 20 to 45 years, were randomized to be prompted to think of one of two different "types" of behaviors, i.e., small level of alcohol use in pregnancy and ambiguous level of alcohol use in pregnancy. They then completed measures of theoretical variables, impulsivity, venturesomeness, and self-efficacy. Participants then answered whether they intended to use alcohol during a future pregnancy.Results: Over half of the variance in intentions to consume alcohol while pregnant were predicted by the final model (R2= .527, F (1, 438) = 13.201, p < .001). Positive attitudes toward alcohol use in pregnancy, from the theory of planned behavior, were the most significant predictor of intentions and intentions did not differ between groups according to prototype exposure.Conclusions: Future research should aim to explore the efficacy of interventions to reduce low to moderate alcohol use in pregnancy that utilize both the theory of planned behavior and prototype/willingness model to target determinants of intentions.

Is 'a little' too much?: An exploration of women's beliefs about alcohol use during pregnancy.

Objective: Interventions to address alcohol use during pregnancy need to target underlying determinants of the behaviour. Using the theory of planned behaviour as a theoretical framework, the aim of this study was to identify behavioural, normative and control beliefs regarding alcohol use during pregnancy among a sample of women. Design: 435 women completed a 15-minute online questionnaire designed to identify beliefs about alcohol use during pregnancy. Data were categorised according to type of belief and then summarised and described. Results: The majority of respondents saw few advantages of consuming alcohol during pregnancy and believed that most people would disapprove of alcohol use during pregnancy. Although most women endorsed alcohol abstinence during pregnancy, views on the perceived risk of different levels of alcohol use and perceptions of the 'typical' person who drinks while pregnant varied between participants. Conclusion: This work contributes to the understanding of women's beliefs about alcohol use during pregnancy. Future research should explore how women's beliefs inform their decision making about different levels of alcohol use in pregnancy. Additionally, further research or messaging about alcohol use in pregnancy must also consider the potential for contributing to stigmatising beliefs.
