Potential conceptual framework adapted from McBride et al. [10]. Displays the conceptual framework that will be explored schematically. We hypothesize that pregnancy can increase intentions to change health behavior when it leads to; (1) increased risk perception (2) positive or negative affective response, (3) changed self-concept, based on McBride’s framework [10]. Social support is the fourth factor in this conceptual framework, which was added to the initial framework as this was considered to be a relevant factor in previous TM literature in pregnant women [22, 24, 31]
