Proportion drinking any alcohol in the last month during pregnancy (Aims 3a/3b) |
Participants will report at each survey how often they had a drink with alcohol in the last month. The outcome will be the predicted probability of drinking alcohol over PMC survey observations during which participants are pregnant, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 9 months, during pregnancy |
|
Other |
Proportion drinking more than four drinks at a time in the last month (Aims 3a/3b) |
Participants will report at each survey how often they drank four or more alcoholic drinks at a time (heavy episodic drinking) in the last month. The outcome will be the predicted probability of heavy episodic drinking over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |

Other |
Proportion reporting physical and/or emotional intimate partner violence (IPV) from the man involved in the pregnancy in the last three months (Aim 3a) |
Participants will report at each survey whether the man involved in their pregnancy physically hurt them (physical IPV) or swore at or controlled their behavior (emotional IPV) in the last three months (minors excluded). The outcome will be the predicted probability of experiencing either type of IPV over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |

Other |
Proportion reporting their current physical health to be fair or poor, based on an adapted version of the SF-36 self-rated health item (Aims 3a/3b) |
Participants will respond at each survey to the question about how they rate their current physical health (excellent, very good, good, fair, poor). This self-rated health question is an adaptation of the item on the RAND Medical Outcomes Survey (SF-36) and the item used in the World Health Organization's World Health Survey. The outcome will be the predicted probability of fair/poor physical health over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |

Other |
Proportion of babies born prior to 37 weeks gestation (Aim 3a) |
In the PMC follow-up survey at which participants report having given birth, they will report the date that doctors expected the baby would be born and the actual birth date. Premature birth will be considered a birth occurring prior to three weeks before the due date. |
PMC follow-up survey (6 weeks through 24 months) at which birth is first reported |
|
Other |
Proportion at risk of poor bonding on the Postpartum Bonding Questionnaire (Aims 3a) |
Participants will respond at each survey after the birth of the index child to the Brockington Postpartum Bonding Questionnaire, a 12-item scale, with responses on a 5-point scale from all of the time to never, total range 0-48. A score of =12 is considered to indicate risk of poor bonding. The outcome will be the predicted probability of being at risk of poor bonding over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC follow-up surveys (6 weeks through 24 months), starting at the survey at which birth is first reported |
|
Primary |
Mean score on Cohen's Perceived Stress Scale over 24 months (Aims 3a/3b) |
The Perceived Stress Scale (PSS) measures stress; scores are summed across 4 scale items (brief version), each with responses never to very often, on a 5-point scale, for a score ranging 0-16. The outcome will be the predicted mean PSS score over the 8 PMC survey observations (a single measure of effect), based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |
|
Primary |
Proportion experiencing moderate to severe depressive symptoms on the PHQ-8 over 24 months (Aims 3a/3b) |
Patient Health Questionnaire (PHQ-8) measures depression symptoms; scores are summed across the 8 items, each with responses not at all to nearly every day, on a 4-point scale, for a score ranging 0-24. Those scoring = 10 are considered to have moderate to severe depression. The outcome will be the predicted probability of a PHQ-8 score = 10 over the 8 PMC survey observations (a single measure of effect), based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |
|
Primary |
Proportion experiencing moderate to severe anxiety symptoms on the GAD-7 over 24 months (Aims 3a/3b) |
Generalized Anxiety Disorder (GAD-7) measures anxiety symptoms; scores are summed across the 7 items, each with responses not at all to nearly every day, on a 4-point scale, for a score ranging 0-21. Those scoring = 10 are considered to have moderate to severe anxiety. The outcome will be the predicted probability of a GAD-7 score = 10 over the 8 PMC survey observations (a single measure of effect), based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |
|
Primary |
Proportion of pregnancies ending in childbirth and childraising, among those who reported ever considering the option (Aim 2) |
Participants will report at each survey whether they considered each pregnancy option, as well as the status and outcome of their pregnancy. The outcome will be the proportion of participants whose pregnancies ended in childbirth and childraising, among those who ever reported considering giving birth and raising the child on a follow-up survey. |
PMC baseline through 12 months |
|
Primary |
Proportion of pregnancies ending in abortion, among those who reported ever considering the option (Aim 2) |
Participants will report at each survey whether they considered each pregnancy option, as well as the status and outcome of their pregnancy. The outcome will be the proportion of participants whose pregnancies ended in abortion, among those who ever reported considering abortion on a follow-up survey. |
PMC baseline through 12 months |
|
Primary |
Proportion of participants obtaining prenatal care, among those who ever reported seeking prenatal care (Aim 2) |
Participants will report at each survey whether they sought prenatal care, abortion care and/or adoption services and whether they obtained each type of care. The outcome will be the proportion of participants who obtained prenatal care, among those who ever reported seeking prenatal care. |
PMC baseline through 12 months |
|
Primary |
Proportion of participants obtaining abortion care, among those who ever reported seeking abortion care (Aim 2) |
Participants will report at each survey whether they sought prenatal care, abortion care and/or adoption services and whether they obtained each type of care. The outcome will be the proportion of participants who obtained abortion care, among those who ever reported seeking abortion care. |

Secondary |
Proportion living below 100% of the Federal Poverty Level (FPL) (Aims 3a/3b) |
Participants will report on all surveys their household income and size. We will calculate the FPL cut-point based on the specific year's US Census Bureau FPL. The outcome will be the predicted probability of living below 100% FPL over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |

Secondary |
Mean MacArthur Scale of Subjective Social Status score over 24 months (Aims 3a/3b) |
Participants will rank themselves on the MacArthur Scale of Subjective Social Status (SSS) ladder (1-10) at all surveys. The outcome will be the predicted mean score over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |
PMC baseline through 24 months |

Secondary |
Proportion employed full or part time (Aims 3a/3b) |
Participants will report on all surveys their current employment status. The outcome will be the predicted probability of being employed (full or part time) over the 8 PMC survey observations, based on the marginal effect from a longitudinal multivariable mixed effects model. |

Secondary |
Time until dropping out of or leaving school (Aims 3a/3b) |
Participants will respond to questions at each survey about their current enrollment in school, type of school attended, degree sought, changes in enrollment since prior survey, degree completion/incompletion, and educational aspirations. Dropping out will be examined as, among those in a degree or other educational program at PMC baseline, time until stopping the degree for a reason other than completion. |
