Effect of Presenting Survival Information as Text or Pictograph During Periviable Birth Counseling
Effect of Presenting Survival Information as Text or Pictograph During Periviable Birth
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.

Detailed Description
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hypothetical treatment choice
Time Frame: Assessed immediately post-intervention
|
Participant's hypothetical treatment choice of either palliative care or intensive care.
Participants are told: "If the child was actually born shortly after the conversation described above, which treatment would you prefer if you were in this situation?"
and given the options of "Palliative care treatment" or "Intensive care treatment".
This variable is assessed for the frequency of each option chosen.
|
Assessed immediately post-intervention
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Religiosity
Time Frame: Assessed post-intervention, immediately after treatment choice.
|
Participants' religiosity was assessed using the Duke University Religion Index (5-item).
Potential scores range from 5-27, with 27 being the most religious.
|
Assessed post-intervention, immediately after treatment choice.
|
Health literacy
Time Frame: Assessed post-intervention, immediately after treatment choice.
|
Participants' health literacy was assessed using the single-item Brief Health Literacy screening, which asks, "How confident are you filling out medical forms by yourself?
Extremely / Quite a bit / Somewhat / A little bit / Not at all." Participants who answered somewhat, a little bit, or not at all were considered to have low health literacy.
|
Assessed post-intervention, immediately after treatment choice.
|
Values: Quality of life or Sanctity of life
Time Frame: Assessed post-intervention, immediately after treatment choice.
|
Participants answered the following: "In making end-of-life decisions: 1) Quality of life is much more important than preserving life, 2) Quality of life is somewhat more important than preserving life, 3) Preserving life is somewhat more important than quality of life, or 4) Preserving life is much more important than quality of life."
In the range of 1-4, a score of 4 indicated the greatest participant value of sanctity of life.
|
Assessed post-intervention, immediately after treatment choice.
|
Preference for medical autonomy
Time Frame: Assessed post-intervention, immediately after treatment choice
|
Participants were asked on a 4-point scale their medical autonomy preferences, in the form of: "In making medical decisions... 1) I always prefer to have the doctor make medical decisions for me.
2) I would prefer to have the doctor make medical decisions for me most of the time.
3) I would prefer to make my own medical decisions most of the time.
4) I always prefer to make my own decisions."
|
Assessed post-intervention, immediately after treatment choice
|
Subjective numeracy
Time Frame: Assessed post-intervention, immediately after treatment choice.
|
Participants' subjective sense of their own numeracy skills will be assessed using a 3-item version of the Subjective Numeracy Scale (SNS-3).
On a 6-point scale, from "Not good at all" to "Extremely good", participants respond to: 1) "How good are you at working with fractions?",
2) "How good are you at figuring out how much a shirt will cost if it is 25% off?", and 3) "How often do you find numerical information to be useful?"
|
Assessed post-intervention, immediately after treatment choice.
|
Subjective sense of probability
Time Frame: Assessed post-intervention, immediately after treatment choice.
|
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. Responses will be coded numerically on a 100-point scale. |
