Women recruited from the internet will be put in a hypothetical situation of being in labor at 22 weeks of pregnancy, and presented with information on the likelihood of survival and chance of disability for babies born at this gestational age.
Participants will be randomized to receive this outcome data in one of three formats: as text-only, in a static pictograph, or in an iterative pictograph. Participants will also be randomized to seeing the chance of survival as 30% or 60%.
Participants were then asked to choose between comfort care and intensive care in this situation. Participants' religiosity, value of the sanctity of life, and health literacy were also assessed.
A recent study by Kidszun et al. (2020) concluded that for mothers placed in a hypothetical situation of choosing between comfort care and intensive care at 22 weeks gestation, treatment choice was not influenced by the chance of survival. Specifically, there was no difference in treatment choice between moms who were told the baby would have a 30% chance of survival and moms who were told the baby would have a 60% chance of survival.
The study was conducted using a written vignette that included a paragraph on the chance of survival and the chance of disability among the survivors.
In this study, we will adapt the vignette the Kidszun et al. (2020) team used, and provide it to an internet-based sample of women. In this vignette, participants will be put in a hypothetical situation of being in labor at 22 weeks of pregnancy, provided a description of the treatment choices of intensive care or comfort care, and provided data on outcome information at this gestational age.
After reading the vignette, participants will be randomized to view either: a repeat of the text information on outcome data, a static pictograph, or an iterative pictograph. Participants will also be randomized to seeing the chance of survival as 30% or 60%, making this a 2 (chance of survival) x 3 (data presentation format) between-subjects experiment.
After viewing a repeat of the outcome information, participants will be asked to choose between intensive care or comfort care for their hypothetical child. We will also collect information on values, religiosity, health literacy, subjective numeracy, a subjective probability estimate, and demographics.

| Subjective Sense of Probability | After reporting an objective value of the probability of survival that has been described to them in the vignette and intervention, participants report their subjective sense of probability. Specifically, they will read: "Assume again that your baby was born prematurely at 22 weeks and given intensive care treatment. The doctor gave you the same information you read earlier. At a gut level, what would you believe is your own baby's actual chance of survival? Please click somewhere along the bar below to indicate your response." Participants use a slider scale below the item to respond from "No chance of survival" to "Definitely will survive". Responses will be coded numerically on a 100-point scale, with 0 representing "No chance of survival" to 100 representing "Definitely will survive". | Assessed post-intervention, immediately after treatment choice. |
