Brief Summary

The ADAPT Study is a longitudinal observational cohort study examining women's pregnancy preferences, pregnancy decision-making processes, and the effects of less preferred (commonly called "unintended") pregnancy on women's lives. This study will enroll and follow prospectively an Underlying Cohort (UC) of women who are not pregnant at baseline. The study will measure the degree to which participants desire to avoid pregnancy multiple times over the course of the year and capture incident pregnancies as they occur over time. Participants experiencing new pregnancies during the one-year UC will be transferred into a new cohort, the Pregnancy and Match Cohort (PMC); these women will be followed over the course of their pregnancy decision-making and health care-seeking to document these processes. In addition, they will be followed through their pregnancies and giving birth to investigate differences in health, well-being, and socioeconomic outcomes associated with carrying a pregnancy to term based on the participant's pre- and post-pregnancy preference about the pregnancy. Finally, a cohort of non-pregnant women from the UC, matched on desire to avoid pregnancy and time at risk of pregnancy, will be followed as part of the PMC. The study will compare the health, well-being, and socioeconomic outcomes of women with new pregnancies and new births to those in the non-pregnant group to assess the effect of pregnancy itself on women. The ADAPT study has the following aims: Aim 1: Assess the factors associated with women's pregnancy preferences, how preferences change over time, and their associations with contraceptive use, incident pregnancy, and feelings about the pregnancy after discovery (Underlying Cohort) Aim 2: Investigate the options that women consider when they become pregnant and the factors that influence their pregnancy decision-making and ability to access desired reproductive health care and services (prenatal, abortion, adoption) (Study A) Aim 3a: Examine the effects of giving birth from a less preferred (or "unintended") pregnancy, measured prospectively on a continuum, as compared to a more preferred pregnancy, on women's health and well-being (Study B1) Aim 3b: Examine the effects of experiencing pregnancy and birth on women's health and well-being, as compared to not experiencing pregnancy (Study B2) This is a social science, behavioral study and does not use clinical data or biological markers.

Outcome Measures

Primary Outcomes (7)

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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.

    PMC baseline through 12 months

Study Arms (3)

Underlying Cohort

The study will recruit and follow a prospective cohort of women "at risk" of pregnancy for one year.

Interventions

The primary exposure of interest for Aim 1 will be pregnancy preferences, measured with the Desire to Avoid Pregnancy scale.

Underlying Cohort

For Aim 2 will assess the roles of contextual and individual variables on pregnancy decision-making and care-seeking outcomes (including state political environment, stigma, social emotional and instrumental support, feelings about the pregnancy, SES).

Pregnancy Match Cohort, Pregnant Group

The primary exposure of interest for Aim 3a will be pregnancy preferences, measured with the Desire to Avoid Pregnancy scale.

Pregnancy Match Cohort, Pregnant Group
