CT intervention
The CT intervention was developed using Tailorbuilder software (OSE, the Netherlands), a program which is specifically designed to develop web-based computer-tailored interventions.
Similar to the HC intervention, the CT intervention consisted of three feedback sessions. Feedback 1 was given after the baseline questionnaire following registration. This feedback was tailored to the determinants of the participant assessed in the baseline questionnaire. First, after the assessment of the participant’s alcohol use, factual information was provided on the consequences of alcohol use during pregnancy. Then, by providing feedback on participant’s responses to the absolute and comparative measures of risk perception, risk perception was used to increase participant’s motivation to stop drinking alcohol. Participant’s attitude on alcohol abstinence during pregnancy was used to confirm the perceived advantages and counter the perceived disadvantages. Social influences were reflected on and participants were encouraged to consider what kind of social support was needed. Subsequently, situations for which the participants had the lowest level of confidence that they would abstain from alcohol were assessed and reflected on. Then, participants were stimulated to make action and coping plans to carry out the behaviour change and cope with difficult situations. Finally, participants set a date for quitting their alcohol use.
Feedback 2 took place six weeks after baseline and was once more based on the assessment of participant’s determinants in the baseline questionnaire. Specifically, the participant could choose one or more characteristics assessed with the baseline questionnaire (for example, risk perception or attitude) and compared to Feedback 1, received more elaborate information on her selection of characteristics. For example with regard to attitude, Feedback 1 consisted of general information on the advantages of alcohol abstinence and disadvantages of prenatal alcohol use. Accordingly, it was stated that a positive attitude towards alcohol abstinence would help the participant to abstain from alcohol. In contrast, in Feedback 2, participants received specific item-based
