Psychological Interventions for Prenatal Anxiety in Latinas and Black Women: A Scoping Review and Recommendations

Abstract

Anxiety symptoms are common among pregnant women worldwide. In the United States, prenatal anxiety symptoms tend to be elevated among Black and Latin American women as compared to non-Latina White women. Despite the high prevalence of anxiety and associations with adverse maternal and offspring outcomes, interventions have not been developed or tailored sufficiently to Black women or Latinas who need efficacious treatment. This article provides a scoping review of articles published since 2017 that test the effects of randomized and non-randomized psychological interventions designed to reduce prenatal anxiety in samples comprised primarily of ethnic/racial minority women. We also review published protocols of planned psychological interventions to reduce prenatal anxiety in order to highlight novel approaches. In addition to summarizing intervention efficacy and participant acceptability, we highlight gaps in the literature which, if addressed, could improve perinatal mental health equity. Finally, we discuss future directions in prenatal anxiety intervention science beginning preconception including intervention design and prevention models.

Anxiety is the most prevalent psychological disorder and it disproportionately affects women. The lifetime prevalence of anxiety disorders in adult women residing in the United States is 40% (1). During pregnancy, pooled prevalence rates indicate that about 15% of women will meet diagnostic criteria for an anxiety disorder (2). Self-reported prenatal anxiety symptoms differ by race and ethnicity. In particular, approximately one third of Black women and Latinas in the U.S. experience elevated anxiety symptoms (3) due in part to structural oppression, which increases financial, relationship, and discrimination related stress in general and during pregnancy (4, 5).

Functional impairment resulting from prenatal anxiety can manifest in ways that adversely affect a woman and her pregnancy. For example, pregnant women with anxiety are less likely to adhere to prenatal care recommendations such as abstaining from substance use or engaging in positive health behaviors (6, 7). They may also avoid prenatal healthcare because it can trigger health-related worries (8). Additionally, prenatal anxiety has been associated with adverse health outcomes for mothers and their infants—specifically postpartum depression, shorter gestation, low birthweight, impaired infant neurodevelopment, and behavioral problems later in childhood (9–11). Given its high prevalence and associated long-term health risks for mothers and their children, prenatal anxiety screening and interventions are urgently needed.

Treatments for anxiety in adults include psychotherapy and medication. However, the safety of psychotropic medications in pregnancy continues to be debated. While medications such as benzodiazepines and serotonin reuptake inhibitors have been reliably linked to adverse infant outcomes (e.g., low birth weight, pre-term birth), the magnitude of these risks is not yet established (12, 13). Additionally, in cases where anxiety is severely impairing, providers must weigh whether abstaining from medication might result in symptom exacerbation (14) with negative consequences for mothers and offspring. Thus, while the American College of Obstetricians and Gynecologists (15) maintains that the cost-benefit analysis for medication ought to be made on a case-by-case basis, psychotherapy is widely considered as a first line intervention to reduce prenatal anxiety.

Nonetheless, referrals to psychotherapeutic services in obstetric settings are infrequent (16). Among low-income and ethnic and racial minority women, structural barriers including lack of insurance and discrimination in prenatal health care settings (17) reduce regular attendance at prenatal health appointments (18, 19). Less frequent interactions with prenatal health care providers along with stigma surrounding disclosure of mental health concerns (20) also limit the likelihood of coordinated mental health care among pregnant ethnic and racial minority women. Survey data substantiate disparities in service utilization by women of color. In a representative sample of over 2,100 women who gave birth in California in 2016, Black women and Latinas utilized perinatal mental health services at significantly lower rates than their non-Latina counterparts despite having more internalizing symptoms (21). Thus, for a variety of reasons, psychotherapy is underutilized during pregnancy and particularly among Black women and Latinas.

Compounding barriers to obtaining mental health services in pregnancy is the need for more evidence regarding which interventions are most likely to be effective. For example, Cognitive Behavioral Therapy (CBT) is considered a gold-standard intervention for anxiety in the general population (22), but is infrequently tested in pregnant samples. Results from intervention studies with small sample sizes (most n's <15) have shown mixed effects of CBT on prenatal anxiety. That is, some studies show CBT to be beneficial in reducing prenatal anxiety symptoms (23–25), whereas others show no intervention effects (26, 27).

In RCTs that enroll a significant number of ethnic and racial minorities, investigators infrequently report results by race and ethnicity (28), masking whether existing prenatal interventions are equally effective for Black women and Latinas. In general, testing the relative efficacy of evidence-based psychotherapies across racial/ethnic groups is much needed. Research to date suggests that ethnic and racial minorities show better psychological outcomes when treated with culturally adapted intervention protocols as compared to standard protocols (29). Thus, assessing whether prenatal intervention effects are generalizable to Black women and Latinas is critical, and can help identify particular psychotherapy modalities or styles of delivery in need of cultural tailoring (30). For example, intervention protocols that standardize clinical consultation with case managers to address system-level factors like housing insecurity that contribute to women's prenatal anxiety may enhance the efficacy of prenatal interventions among at-risk populations.

A recent systematic review evaluated the treatment outcome literature among Black or Latina pregnant women who received a psychological intervention to reduce symptoms of depression or anxiety (31). For inclusion in the review at least 75% of the treatment sample had to identify as Black or Latina. The authors found that that only two published studies—both testing interpersonal therapy—have sought to reduce anxious symptoms during pregnancy (31). In both studies, women who were randomized to the intervention group did not fare better than women in the control condition with respect to a reduction in anxiety symptoms. Therefore, results of the review found that none of the delivered psychotherapies for prenatal anxiety met the criteria to be considered evidence-based among Black women or Latinas.

Data from Ponting et al. (31) show that the last identified anxiety intervention tested with a majority Black and Latina sample was published in 2017. In the present article, we provide an update to the Ponting et al. (31) review by searching for psychological interventions reporting on prenatal anxiety efficacy in studies enrolling at least 50% Black women and Latinas from 2017 through 2021. We also review published protocols for prenatal anxiety reduction during this same time to describe recent patterns in intervention science for prenatal anxiety.

We take a scoping review approach that is appropriate for identifying themes and discussing gaps within a content area (32). This method may be especially helpful when the content area has a limited evidence base, as is the case for anxiety interventions in pregnancy. Based on our review, we suggest several directions to improve efficacy and equity in psychotherapy research for prenatal anxiety as yet.

Method

Eligibility Criteria

We utilized a scoping review methodology (32) to search for psychological interventions published during the last 5 years (2017–2021) to treat prenatal anxiety in ethnic and racial minorities. The written protocol for this scoping review was adapted from a previously registered protocol of the authors (see: Prospective Register of Ongoing Systematic Reviews ID: CRD42018106228) in three ways. First, only studies treating anxiety were included. Second a smaller proportion of the treatment sample had to identify as Black or Latina (i.e., >50 vs. >75%). Third, published protocols with anxiety outcome measures were included even if they did not yet have efficacy data.

Thus, studies were included if they tested a psychological intervention delivered during pregnancy, and if they reported on a standardized instrument to measure anxiety (e.g., GAD-7; STAI) at pre and post treatment. Samples had to be comprised of at least 50% Black or Latina participants, a standard used in prior perinatal intervention reviews with ethnic and racial minority women (33). Given the dearth of efficacy studies for prenatal anxiety, we also included published intervention protocols for treating anxiety in pregnancy. Intervention protocols describe RCTs currently in progress. Although we cannot yet report on their efficacy, they reflect upcoming advances in prenatal anxiety treatment modality and delivery. Studies on psychopharmacology or complementary and alternative therapies (e.g., massage, yoga) were excluded.

Search Strategy

The research team consulted with an experienced research librarian to develop search terms for the scoping review (all search syntax is available in Supplement). Five databases were searched: PubMed©, CINAHL©, PsycINFO©, ProQuest Dissertation and Theses AI©, and Web of Science Articles published from January 2017 through September 2021. In total, searches produced 240 studies. Duplicates were identified using Rayaan (34), an online tool, and confirmed by a member of the review team, leaving 191 unique articles.

The methods sections of the 191 articles were examined next. One reviewer screened study abstracts for eligibility based on inclusion/exclusion criteria and consulted with the research team to reach consensus if unsure about inclusion (see Figure 1 for detailed information about exclusion). At this stage, a total of 172 articles were excluded, in most cases because studies did not test a psychological intervention, and instead were observational studies of mental health during pregnancy (n = 130). Rayaan (34) was used to store all article abstracts and catalog the reason for inclusion or exclusion. The remaining 19 articles underwent full-text review, during which 16 articles were excluded. Scanning reference sections (e.g., snowball approach), and searching Google Scholar (35) increased search comprehensiveness and led to the addition of seven articles. Thus, a total of seven studies met all inclusion criteria for this scoping review—two were intervention efficacy studies and five were registered intervention protocols for prenatal anxiety.

Data Extraction

The following were extracted from the two intervention efficacy studies: (1) intervention characteristics (intervention format, treatment modality, provider type, number of sessions, setting); (2) participant demographics (race/ethnicity), (3) U.S. vs. foreign born, and indicators of income); (4) the perinatal period during which the intervention was delivered; (5) type of study design (e.g., RCT, pre-post design); (6) outcomes pertaining to anxiety; (7) the use of cultural adaptations; and (8) intervention acceptability data. The same variables were extracted for studies reporting on intervention protocols (n = 5), except for treatment response data given that efficacy data was not yet available. The first author extracted these data and charted them independently using a table approved and tested by the research team; data validity and accuracy were checked by a research assistant.

Data Quality Assessment

The methodological biases of the empirical treatment studies in this review were assessed using the Cochrane risk of bias assessment. Specifically, six categories of bias are assessed: (a) selection bias, (b) performance bias, (c) detection bias, (d) attrition bias, (e) reporting bias, and (f) baseline imbalance. The protocols for RCTs that are included were not subjected to a data quality assessment for two reasons. First, the randomized nature of the proposed studies indicated low overall biases, and second, outcome data were not yet reported, meaning that bias categories like attrition bias, reporting bias, and baseline imbalances were not able to be assessed. Bias ratings can be found in Table A1.

Results

Prenatal Anxiety Intervention Efficacy

Two studies provided data on initial clinical efficacy for prenatal anxiety among Latinas and Black women. Lenze and Potts (36) tested an RCT (n = 42) with a majority low-income Black (79%) sample enrolled during their first trimester of pregnancy. The authors reported that women randomized to nine sessions of individual interpersonal psychotherapy for depression delivered by mental health professionals, did not show significant reductions in anxiety symptoms (a secondary outcome). This study was considered to have low methodological bias.

The second study authored by Ruiz et al. (37) used a non-randomized pre-post intervention design (n = 15) with a low-income Latina-only sample (31% were foreign born) enrolled during their first trimester of pregnancy. Authors reported that following the receipt of a six-session culturally-adapted combined Acceptance and Commitment Therapy (ACT) and Problem Solving Therapy (PST; delivered by nurse practitioners and midwives), women showed significant reductions in their prenatal anxiety symptoms from baseline to post-intervention. Participants in both studies provided quantitative data about the acceptability of the interventions; scores revealed high levels of satisfaction. This study was considered to have high methodological bias (see Table A1 for bias ratings).

Registered Protocols for Treating Prenatal Anxiety

For full information on protocol characteristics see Table 1. We identified eight intervention protocols for prenatal anxiety published since 2017. Most protocols (n = 6) were RCTs proposing to test the efficacy of CBT. These protocols involved delivery of CBT face-to-face (38, 40, 41, 43), online (42, 45), or in combination with a positive parenting intervention (43). One protocol compared an enhanced Prenatal Positive Parenting Program with Mellow Bumps, an intervention focused on promoting antenatal health and mother-infant attachment (44). Face-to-face interventions planned to use hospital or prenatal clinic dissemination settings (38, 40, 41, 43) and delivery models reliant on prenatal nursing professionals (38, 40, 41, 44). Six studies planned to deliver their interventions individually (38, 41, 42), and the other two planned to deliver them in a group setting (43, 44). Three of the five protocols made explicit reference to techniques under consideration to improve cultural fit of their interventions with historically excluded groups of pregnant women (38–40, 43–45), and five planned to collect acceptability data from enrolled women (38–41, 44).

Discussion

This scoping review sought to update current knowledge in the last 5 years (2017–2021) on psychological intervention efficacy for prenatal anxiety in samples comprised of at least 50% Latinas or Black women. Only two completed and published studies met criteria for inclusion; of those, a non-randomized trial testing an intervention integrating ACT and problem-solving therapy in a small Latina sample (n = 15) showed beneficial effects for prenatal anxiety. A prior systematic review without any date restrictions and a higher threshold for ethnic/racial minority inclusion (i.e., 75%) also identified only two trials seeking to reduce prenatal anxiety (31). The present review, using a less stringent inclusion criteria for proportion of Latinas or Black women enrolled, found just one new published intervention trial since Ponting et al. (31). Thus, to date there are a total of three published studies (total n = 101)—two in primarily Black samples, one in a Latina only sample—that have sought to treat prenatal anxiety in Latinas or Black women. Meta-analytic data indicate that there are nine additional published RCTs comprised of primarily white women (total n = 443), most testing CBT, that show medium effect sizes of psychotherapy on prenatal anxiety (46). Thus, although there are relatively few prenatal anxiety interventions overall, there is evidence of symptom improvement for non-Latina white women, but not as yet for Latinas or Black women. This gap in the literature requires attention by researchers and clinicians.

We also reviewed published protocols for RCTs testing interventions for prenatal anxiety. Despite the identified disparity in efficacious anxiety interventions for Black women and Latinas, the eight protocols identified are encouraging for at least two reasons. First, four of the eight protocols planned to train nurses and midwives who are perinatal health professionals without a mental health background. This is likely to be a promising approach. The feasibility of this delivery model is supported by nurses and midwives' frequent contact with pregnant women and extensive training in pregnancy-specific health information (47). In conjunction with increased funding for home visiting programs for pregnant women under the Affordable Care Act, this workforce is well-positioned to address common pregnancy-specific worries and concerns. Recent meta-analyses find that midwife-delivered psychological interventions are efficacious for reducing perinatal anxiety and depression (48, 49).

Second, three of the protocols (38, 43, 44) identify theoretical mechanisms of treatment change, which can serve as psychosocial targets across psychotherapeutic modalities. For example, the O'Brien et al. (44) protocol stands out because the proposed mediators of change are situated within the developmental context of pregnancy. The enhanced Triple P for Parenting and Mellow Bumps protocol is teaching pregnant women and their partners about infant and child development and will test whether improvements in knowledge around infant development will lead to maternal anxiety symptoms. Though psychologists have urged for better measurement of potential mechanisms of intervention that are related to symptom change [e.g., (50)], prenatal intervention work has lagged in this domain. Identifying the psychosocial targets most likely to lead to improved anxiety profiles during pregnancy is a worthy avenue for future investigation.

Future Considerations to Improve Equity in Prenatal Anxiety Intervention

The disproportionate impact of socio-political stressors on Black women and Latinas in the United States adversely impacts anxiety symptoms among these groups (51), and we lack evidence-based psychotherapies to intervene at the individual level in pregnancy. In this context of high unmet need, we argue that increased attention to family involvement, pregnancy-specific anxiety, and prevention efforts during preconception (52) are likely to improve engagement and clinical outcomes among ethnic and racial minority pregnant women.

Our recommendation is to include a woman's family members as part of perinatal anxiety interventions to increase her comfort and involvement with treatment. We know that pregnant women have significant interest in receiving family support during their prenatal health care (53), yet no published intervention identified in the present systematic review or in past reviews (31, 54) have involved partner or extended family participation. Public health programs have increasingly sought to involve partners in perinatal care given that couples' anxiety symptoms have bidirectional effects in pregnancy (55) and influence early parenting behaviors (30). There is emerging evidence among samples of primarily white women that brief psychological interventions for pregnant women at risk for anxiety incorporating partners or family can successfully reduce symptoms in both women and their family members (56). The benefits of family engagement may be even greater for pregnant Latinas and Black women whose valuing of close family relationships (e.g., familism) is an important cultural source of resilience during pregnancy (51, 57).

Further, it is possible that familial participation may reduce concerns as reported by the pregnant women in several qualitative studies—that seeking help for anxiety might be negatively perceived as prioritizing themselves over their families (53). However, interventions that consider including partners or family members should take into account history of family violence and prioritize safety as well as ensure that women feel comfortable including their family in such interventions.

Recent research draws attention to a range of pregnancy-specific worries that should be addressed in prenatal anxiety interventions (9). Pregnancy-specific anxiety—or concerns specific to a woman's pregnancy, labor and delivery, and future parenting—is estimated to occur in 29% of women in high income countries (58). Yet, intervention protocols for prenatal anxiety often leave out content about labor and delivery, or about common prenatal medical conditions in pregnancy (e.g., gestational diabetes, preeclampsia). In fact, fear of childbirth and pregnancy-specific anxiety have largely been treated separately from other anxiety symptoms or disorders, and are frequently addressed using only standard prenatal health education (59). Integrating prenatal health education and psychotherapy may increase intervention relevance and improve birth and child outcomes, improving care for pregnant women with anxiety.

MUMentum (25) is an internet delivered CBT protocol for perinatal depression and anxiety and a good example of integrating psychotherapy and prenatal education. MUMentum supplies prenatal education resources for women, including topics like attachment during pregnancy and intrusive thoughts about childbirth. Efficacy data among Australian women show that randomization to the MUMentum intervention resulted in medium to large reductions in anxiety (25). Examining how MUMentum and other interventions might impact pregnancy-specific anxiety is a worthy next step, as pregnancy-specific anxiety has been linked to length of gestation, low-birthweight, and adverse physical and mental health outcomes for offspring (60). Psychological intervention trials that can better tailor their content to fit specific and prevalent pregnancy-related worries stand to have particular impact on ethnic and racial minority women who are disproportionately likely to report high pregnancy-specific anxiety (6, 61, 62) and encounter adverse birth outcomes (63).

Finally, the preconception period—before a person is pregnant— is increasingly a window of interest for psychological interventions seeking to improve the overall health of women during pregnancy. Addressing preconception anxiety merits consideration, as symptoms have been associated with postpartum anxiety and later mother-infant bonding problems (64). Thus, providing health promotion information and screening for anxiety symptoms during preventive visits might be worthwhile, especially if women are of reproductive age and are seeking to be pregnant. This same strategy can be applied to interconception periods and appears to be an indicated and low burden form of prevention for women with a prior adverse pregnancy outcome [e.g., traumatic delivery, fetal loss; (65)]. Though referral and treatment may improve women's health broadly and set the stage for a healthier pregnancy in the future, equitable outcomes will require that screening and education is culturally responsive, treatment is disseminated outside of health care settings, and that providers acknowledge historical and current reproductive oppression (66).

In conclusion, this scoping review provides a strong basis for empirically testing and culturally tailoring prenatal anxiety interventions to optimize the health of racial and ethnic minority mothers and their infants. Given longstanding disparities between Black and Latina and non-Latina white women in pre- and postnatal health outcomes and in access to preventive interventions, policy changes are a pre-requisite for prenatal mental health equity. Still, at the individual level, community-based psychological intervention studies for Black women and Latinas can help to identify particular skills, knowledge, and connections to community support best suited for regulating prenatal anxiety. The success of these endeavors will depend on researchers' ability to engage with community stakeholders to appropriately address mistrust of intervention research given historical abuses and current inequities in care in minority communities (67). Researchers can assess intervention acceptability among Latinas and Black women and address pregnancy-specific worries or basic needs to increase the relevance of available treatments for prenatal anxiety. Health promotion programs that can build on the strengths of Latinx and Black communities in the preconception period are also warranted to improve intergenerational outcomes.
