Clinical Trial Summary

Detailed Description The doula-led intervention developed during the first phase of this project will be pilot tested for feasibility. Following the recruitment procedures described in the recruitment and retention plan, approximately 75 participants will be enrolled into the study. Twenty-five of the participants will receive regular doula care and 25 of the participants will receive care from a doula trained in the PMAD doula training throughout their pregnancy, childbirth, and postpartum time period, following the intervention procedures developed in Aim 2 of this study. Twenty-five women will not receive care from a doula and will receive perinatal care as usual. Women in all groups will take surveys via REDCap during their enrollment in the intervention, at 1 month postpartum, 3 months, and 6 months postpartum (at the conclusion of the intervention). All participants who receive the PMAD doula intervention will complete checklists after each session with their doula, to assess fidelity to the intervention. Participant communication with their doula via patient notebook will also be assessed for fidelity to the intervention.

Detailed Description The doula-led intervention developed during the first phase of this project will be pilot tested for feasibility. Following the recruitment procedures described in the recruitment and retention plan, approximately 75 participants will be enrolled into the study. Twenty-five of the participants will receive regular doula care and 25 of the participants will receive care from a doula trained in the PMAD doula training throughout their pregnancy, childbirth, and postpartum time period, following the intervention procedures developed in Aim 2 of this study. Twenty-five women will not receive care from a doula and will receive perinatal care as usual. Women in all groups will take surveys via REDCap during their enrollment in the intervention, at 1 month postpartum, 3 months, and 6 months postpartum (at the conclusion of the intervention). All participants who receive the PMAD doula intervention will complete checklists after each session with their doula, to assess fidelity to the intervention. Participant communication with their doula via patient notebook will also be assessed for fidelity to the intervention. A subsection of 20 participants who receive care from doulas in the PMAD training will also be eligible to participate in a qualitative interview at 6 months postpartum. The interview guide will be developed based on prior research with doulas, the PI's current research exploring doula-care in Montana, and feedback from the CAB. Example questions are expected to include: "What were your experiences working with a doula?" "What would have made your experience better?" and "What worked and what didn't work?" Interviewers will all be graduate students who have completed research methods courses and will be trained by the PI, who has extensive experience in conducting qualitative research and in conducting qualitative interviews. The following procedures will be followed: 1. Once participants have indicated that they are interested in participating in the study, the PI will contact them to set up a time to discuss the study with them, and if they are interested and meet eligibility criteria, enroll them in the study. Participants will be randomly assigned to either receive standard care from a doula, the doula PMAD intervention, or perinatal care as usual. 2. Before enrollment in the study, participants will be provided with a copy of the consent form, and the information on the consent form will be read to the participants. 3. Once the participants have provided informed consent, they will be given the pre-test survey via REDCap and will take the survey again at 1 month postpartum and 3 months postpartum. 4. All participants will be connected to a doula and receive either care as usual from a doula or a doula trained in the intervention by the PI and will engage in care with them throughout their pregnancy, during childbirth, and for 3 months postpartum. The exact components of the doula care provided will be developed in aim 2 based on the findings of study 1. 5. Participants will be provided compensation (in the form of a gift card) after the completion of each survey (pre-test, 1 month postpartum, 3 and 6 months postpartum). 6. At the completion of the study, participants will be thanked for their time and participation. For those who agreed to do member checks, participants will be re-contacted after analysis for member checks. Participants who are randomized into the intervention arm of the study will also be randomly selected to participate in cross-sectional, semi-structured interviews. Participant recruitment is described in the recruitment and retention plan. Participants will be interviewed about experience in the intervention. The following steps will be followed: 1. Once participants have indicated that they are interested in participating in the interview portion of the study, the PI will contact them to set up a time for an interview and about their preferred interview site. They will have the option to do a phone interview if they are not available for an in-person interview or if they are not comfortable with an in-person interview for privacy reasons. The first interview will take place before they begin care with their doula. 2. Interview sessions will be scheduled at a pre-determined time at locations desired by the participants. If the interview takes place in person, Covid-19 protocols will be followed and include the completion of a Covid-19 symptom questionnaire by both the participant and the interviewer, the wearing of face masks during the interview, and social distancing. 3. Before beginning the interview, participants will be provided with a copy of the consent form, and the information on the consent form will be read to the participants. This process is further described in the Protection of Human Subjects document. 4. Once the participants have provided informed consent and provided consent to having the interview audio-recorded, the interviewer will begin recording the interview. A semi-structured interview guide will be used to guide the interview. 5. Audio-recorded interviews will follow semi-structured interview guides and last 60-90 minutes. 6. Following the interview, participants will be asked whether they are willing to be contacted to do a follow-up interview at 3 months postpartum. 7. Participants will be provided their compensation. 8. Participants will be thanked for their time and participation. 9. For those who agreed to do a second and third interviews at 3 and 6 months postpartum, the same process will be followed to conduct their second interview.

Primary	The Childbirth Self-Efficacy Inventory (CBSEI)	The Childbirth Self-Efficacy Inventory (CBSEI) is a 60-item self-report instrument that measures self-efficacy expectancies for coping with childbirth. In describing the development of the CBSEI, Lowe (1993) reports that the CBSEI scales have excellent internal consistency reliability (0.86 to 0.96) and factor analysis suggested that each CBSEl scale is unidimensional. Validity of the CBSEI was supported by significant positive correlations with the criterion variables of generalized self-efficacy, self-esteem, and internal health locus of control; and significant negative correlations with external health locus of control and learned helplessness. Validity was also supported by significantly higher self-efficacy scores for multiparous as compared to nulliparous pregnant women.	At study enrollment

Primary	Generalized Anxiety Disorder (GAD)-7	The GAD-7 screens for and is a symptom severity measure for four of the most common anxiety disorders. Spitzer et al.,(2006) describe strong support of the GAD-7: "Studies with the GAD indicate that the internal consistency of the GAD-7 is excellent (Cronbach a = .92). Test-retest reliability is also good (intraclass correlation = 0.83). Comparison of scores derived from the self-report scales with those derived from the MHP-administered versions of the same scales yielded similar results (intraclass correlation = 0.83), indicating good procedural validity. As the cut point increases, sensitivity decreases and specificity increases in a continuous fashion. At a cut point of 10 or greater, sensitivity and specificity exceed 0.80, and sensitivity is nearly maximized. The GAD-7 also has strong construct validity. There is a strong association between increasing GAD-7 severity scores and worsening function on all 6 SF-20 scales."	At study enrollment

Secondary	Drug Abuse Screening Test (DAST)	The Drug Abuse Screening Test (DAST) is a 10- item self-report form used to assess drug use with adults. The following evaluation of the scale is provided by Skinner (1982): The internal consistency reliability estimate was substantial at .92, and a factor analysis of item intercorrelations suggested an unidimensional scale. With respect to response style biases, the DAST was only moderately correlated with social desirability and denial. Concurrent validity was examined by correlating the DAST with background variables, frequency of drug use during the past 12 months, and indices of psychopathology.	At study enrollment

With respect to response style biases, the DAST was only moderately correlated with social desirability and denial. Concurrent validity was examined by correlating the DAST with background variables, frequency of drug use during the past 12 months, and indices of psychopathology.	At 3-months postpartum
