Women's experiences of participating in a prospective, longitudinal postpartum depression study: insights for perinatal mental health researchers

Systematic review of ethical issues in perinatal mental health research

BACKGROUND

Maternal mental health during the peripartum period is critically important to the wellbeing of mothers and their infants. Numerous studies and clinical trials have focused on various aspects of interventions and treatments for perinatal mental health from the perspective of researchers and medical health professionals. However, less is known about women's experiences of participating in perinatal mental health research, and the ethical issues that arise.

AIM

To systematically review the literature on the ethical issues that emerge from pregnant and/or postpartum women's experiences of taking part in perinatal mental health-related research.

METHODS

Systematic review of nine bibliographic databases, from inception to July 2021. Qualitative, quantitative and mixed method studies were included if they reported on ethical issues experienced by perinatal women. Research ethical issues encompassed any issue relating to women's experiences of being offered study information, recruitment, consent, retention and respect for autonomy.Titles, abstracts and full text screening, appraisal of the methodological quality of included studies, and data extraction, were conducted independently by two reviewers.

ETHICAL CONSIDERATIONS

Ethical approval was not required for this systematic review.

FINDINGS

A total of 9830 unique citations was retrieved. Six studies met the inclusion criteria. Studies were clinically and methodologically heterogenous, and only one was purposively designed to explore women's experiences. The key finding was the establishment of trust between the researcher and participant in all stages of the research process. Findings are presented according to recruitment and consent processes, participation and retention, and study follow-up and completion.

CONCLUSION

The establishment of trust between the researcher and perinatal women leads to a dynamic with research ethical implications relevant to all stages of perinatal mental health-related research. Further research on the research ethical issues experienced by perinatal women is required because of the limited literature.

Stigma as a Barrier to Participant Recruitment of Minority Populations in Diabetes Research: Development of a Community-Centered Recruitment Approach

BACKGROUND

The development of evidence-based care geared towards Black and Latina women living with uncontrolled type 2 diabetes is contingent upon their active recruitment into clinical interventions. Well-documented impediments to recruitment include a historical mistrust of the research community and socioeconomic factors that limit awareness and access to research studies. Although sociocultural and socioeconomic factors deter minorities from participating in clinical research, it is equally important to consider the role of stigma in chronic disease intervention studies.

OBJECTIVE

We aim to share our discovery of diabetes-related stigma as an underrecognized impediment to recruitment for the Women in Control 2.0 virtual diabetes self-management education study.

METHODS

Our initial recruitment plan used traditional strategies to recruit minority women with uncontrolled type 2 diabetes, which included letters and phone calls to targeted patients, referrals from clinicians, and posted flyers. After engaging a patient advisory group and consulting with experts in community advocacy, diabetes-related stigma emerged as a prominent barrier to recruitment. The study team reviewed and revised recruitment scripts and outreach material in order to better align with the lived experience and needs of potential enrollees.

RESULTS

Using a more nuanced, community-centered recruitment approach, we achieved our target recruitment goal, enrolling 309 participants into the study, exceeding our target of 212.

CONCLUSIONS

There is a need for updated recruitment methods that can increase research participation of patients who experience internalized diabetes stigma. To address disparities in minority health, further research is needed to better understand diabetes-related stigma and devise strategies to avert or address it.

The Food, Feelings, and Family Study: comparison of the efficacy of traditional methods, social media, and broadcast email to recruit pregnant women to an observational, longitudinal nutrition study

Background

It is well known that recruitment is a challenging aspect of any study involving human subjects. This challenge is exacerbated when the population sought is reticent to participate in research as is the case with pregnant women and individuals with depression. This paper compares recruitment methods used for the Food, Feelings, and Family Study, an observational, longitudinal pilot study concerning how diet and bisphenol A exposure affect maternal mood and cognitive function during and after pregnancy.

Methods

Pregnant women were recruited to this study over a period of 15 months using traditional methods, social media including paid and unpaid posts, and emails broadcast to the university community. Contingency analysis using the Pearson’s Chi-square test was used to determine if recruitment method was associated with likelihood of participation. T-tests were used to analyze Facebook advertisement success. ANOVAs and Fisher exact tests were used to determine if recruitment method was related to continuous and categorical demographics, respectively.

Results

Social media resulted in the largest number of recruits, followed by traditional methods and broadcast email. Women recruited through social media were less likely to participate. In contrast, use of broadcast email resulted in a smaller pool of recruits but these recruits were more likely to be eligible for and complete the study. Most women recruited via social media were the result of unpaid posts to the study’s Facebook page. Paid posts lasting at least 4 days were the most successful. Recruitment method was not associated with participant demographics.

Conclusions

Social media has the potential to recruit a large pool of potential subjects; however, when studies require a large time investment such as the case here, women recruited through social media are less likely to participate and complete the study than women recruited through other means.

Factors Associated With Home Visits in a 5-Year Study of Acute Respiratory Distress Syndrome Survivors

BACKGROUND

Participant retention is vital for longitudinal studies. Home visits may increase retention, but little is known about the subset of patients they benefit.

OBJECTIVE

To evaluate patient-related variables associated with home visits.

METHODS

In a 5-year, longitudinal, multisite, prospective study of 195 survivors of acute respiratory distress syndrome, in-person assessments were conducted at a research clinic. Home visits were offered to participants who could not attend the clinic. Associations between having a home visit, prior follow-up visit status, and baseline and in-hospital patient variables were evaluated with multivariable, random-intercept logistic regression models. The association between home visits and patients' posthospital clinical status was evaluated with a subsequent regression model adjusted for these variables.

RESULTS

Participants had a median age of 49 years and were 56% male and 58% White. The following had independent associations with home visits (adjusted odds ratio [95% CI]): age (per year: 1.03 [1.00-1.05]) and immediately preceding visit incomplete (2.46 [1.44-4.19]) or at home (8.24 [4.57-14.86]). After adjustment for prior-visit status and baseline and hospitalization variables, these posthospital patient outcome variables were associated with a subsequent home visit: instrumental activities of daily living (≥ 2 vs < 2 dependencies: 2.32 [1.29-4.17]), EQ-5D utility score (per 0.1-point decrease: 1.15 [1.02-1.30]), and 6-minute walk test (per 10-percentage-point decrease in percent-predicted distance: 1.50 [1.26-1.79]).

CONCLUSIONS

Home visits were important for retaining older and more physically impaired study participants, helping reduce selection bias caused by excluding them.

The contribution of qualitative research within the PRECISE study in sub-Saharan Africa

The PRECISE Network is a cohort study established to investigate hypertension, fetal growth restriction and stillbirth (described as "placental disorders") in Kenya, Mozambique and The Gambia. Several pregnancy or birth cohorts have been set up in low- and middle-income countries, focussed on maternal and child health. Qualitative research methods are sometimes used alongside quantitative data collection from these cohorts. Researchers affiliated with PRECISE are also planning to use qualitative methods, from the perspective of multiple subject areas. This paper provides an overview of the different ways in which qualitative research methods can contribute to achieving PRECISE's objectives, and discusses the combination of qualitative methods with quantitative cohort studies more generally.We present planned qualitative work in six subject areas (health systems, health geography, mental health, community engagement, the implementation of the TraCer tool, and respectful maternity care). Based on these plans, with reference to other cohort studies on maternal and child health, and in the context of the methodological literature on mixed methods approaches, we find that qualitative work may have several different functions in relation to cohort studies, including informing the quantitative data collection or interpretation. Researchers may also conduct qualitative work in pursuit of a complementary research agenda. The degree to which integration between qualitative and quantitative methods will be sought and achieved within PRECISE remains to be seen. Overall, we conclude that the synergies resulting from the combination of cohort studies with qualitative research are an asset to the field of maternal and child health.

Prevalence and determinants of perinatal depression among labour migrant and refugee women on the Thai-Myanmar border: a cohort study

BACKGROUND

Perinatal depression is a significant contributor to maternal morbidity and mortality globally. Migrant women, particularly those living in low- and middle-income settings, represent a particularly vulnerable group due to stressors experienced before, during and after migration. The vast majority of global migration flows occurring within and between low- and middle-income regions, yet existing evidence focuses predominantly on migrants in high-income destinations. This study aimed to redress this significant gap in the evidence by determining the prevalence and determinants of perinatal depression among migrant women on the Thai-Myanmar border.

METHODS

A cohort of labour migrant and refugee women was followed-up from the first trimester of pregnancy to one month post-partum. Depression status was assessed in the first, second and third trimesters of pregnancy and at one month post-partum using the Structured Clinical Interview for the Diagnosis of DSM-IV Disorders. Women diagnosed with depression had immediate access to care. Data on potential demographic, social and clinical associated factors was collected using a questionnaire. Prevalence and incidence of any depressive disorder and moderate-severe depressive disorder was calculated. Univariable and multivariable logistic regression using complete case analysis was used to estimate odds ratios (OR) of association between exposure variables and depression status.

RESULTS

Five hundred sixty-eight women participated. Period prevalence (from first trimester of pregnancy to one month post-partum) of moderate-severe perinatal depression was 18.5% (95% CI 15.4-21.9%). Overall, 15.4% (95% CI 11.8-19.6%) of women developed new-onset moderate-severe depression during the study period. Forty-two participants received treatment for depression. Risk factors were interpersonal violence (OR 4.5; 95% CI 1.9-11.1); history of trauma (OR 2.4; 95% CI 1.4-4.3); self-reported history of depression (OR 2.3; 95% CI 1.2-4.2); labour migrant status (OR 2.1; 95% CI 1.1-4.0); low social support (OR 2.1; 95% CI 1.1-3.7); and maternal age (OR 1.1 per year; 95% CI 1.0-1.1). Limitations of the study include that culturally specific manifestations of depression may have been missed.

CONCLUSIONS

Perinatal depression represents a significant burden among migrant women on the Thai-Myanmar border. Programmes to address the determinants along with early case identification and effective treatment and referral systems are key to addressing perinatal depression in this low-resource setting.

Participation, retention, and associated factors of women in a prospective multicenter study on Chlamydia trachomatis infections (FemCure)

Prospective studies are key study designs when attempting to unravel health mechanisms that are widely applicable. Understanding the internal validity of a prospective study is essential to judge a study's quality. Moreover, insights in possible sampling bias and the external validity of a prospective study are useful to judge the applicability of a study's findings. We evaluated participation, retention, and associated factors of women in a multicenter prospective cohort (FemCure) to understand the study's validity.Chlamydia trachomatis (CT) infected adult women, negative for HIV, syphilis, and Neisseria gonorrhoeae were eligible to be preselected and included at three sexually transmitted infection (STI) clinics in the Netherlands (2016-2017). The planned follow-up for participants was 3 months, with two weekly rectal and vaginal CT self-sampling and online questionnaires administered at home and at the clinic. We calculated the proportions of preselected, included, and retained (completed follow-up) women. Associations with non-preselection, noninclusion, and non-retention (called attrition) were assessed (logistic and Cox regression).Among the 4,916 women, 1,763 (35.9%) were preselected, of whom 560 (31.8%) were included. The study population had diverse baseline characteristics: study site, migration background, high education, and no STI history were associated with non-preselection and noninclusion. Retention was 76.3% (n = 427). Attrition was 10.71/100 person/month (95% confidence interval 9.97, 12.69) and was associated with young age and low education. In an outpatient clinical setting, it proved feasible to include and retain women in an intensive prospective cohort. External validity was limited as the study population was not representative (sampling bias), but this did not affect the internal validity. Selective attrition, however (potential selection bias), should be accounted for when interpreting the study results.

Associations of body dissatisfaction with anxiety and depression in the pregnancy and postpartum periods: A longitudinal study

BACKGROUND

Pregnancy is a time of increasing vulnerability to the development of body dissatisfaction, anxiety, and depression. The present study aims to examine associations of body dissatisfaction with anxiety and depression at the following points: 6 months before pregnancy (retrospective report); in the first, second, and third trimesters of pregnancy; and up to 6 weeks postpartum.

METHODS

A prospective longitudinal design with a quantitative approach was adopted. A consecutive sample of 1,371 Chinese pregnant women in Hong Kong was assessed using standardized instruments at four time points.

RESULTS

A mixed-effects model with repeated measures revealed that body dissatisfaction and depression symptoms changed across different stages of pregnancy. Hierarchical multiple regressions showed that, after adjusting for the identified risk factors, body dissatisfaction before and during pregnancy were positively associated with antenatal anxiety and depression symptoms. Concurrent body dissatisfaction was positively associated with postpartum depression symptoms.

LIMITATIONS

There was a high attrition rate in the follow-up assessments. Antenatal anxiety symptoms were assessed using the scale for general anxiety, which may not adequately capture the experience of anxiety among pregnant women.

CONCLUSIONS

Primary healthcare practitioners should be made aware of body dissatisfaction among pregnant women in order to facilitate early intervention for anxiety and depression, because untreated psychological disturbance during pregnancy may persist into the postpartum period.

Factors impacting attrition of vulnerable women from a longitudinal mental health intervention study

OBJECTIVE

This study explored factors associated with attrition of vulnerable women from a community-based, longitudinal mental health intervention study.

DESIGN

The study employed a quasi-experimental, nonequivalent comparison group pretest-posttest design. The intervention consisted of six, 90-min meetings featuring education and support.

SAMPLE

One hundred and eighteen women aged 18-88 years enrolled from four urban neighborhoods.

MEASUREMENTS

The team used the Generalized Anxiety Disorder-7, the Primary Health Questionnaire-9, a self-care knowledge for anxiety and depression instrument, and demographics to measure variables.

INTERVENTION

Sessions occurred at trusted neighborhood sites. The team provided transportation, child care, and reminder calls or texts. Community health workers actively encouraged participants to continue in the study. The researchers did not offer financial incentives. Completion of the intervention involved attending four of six sessions.

RESULTS

The study had a 39% attrition rate. Results, using a Chi-square test for independence, indicated significant associations between attrition, neighborhood/homelessness, and family income. Additionally, there were significant associations between attrition, a past diagnosis of anxiety, and a lack of concurrent therapy for anxiety/depression.

CONCLUSIONS

This study identified social determinants and mental health factors linked to the attrition of urban, ethnically diverse, and impoverished women from longitudinal intervention studies.

Pregnant women's experiences and perceptions of participating in the EVERREST prospective study; a qualitative study

Background

The EVERREST Prospective Study is a multicentre observational cohort study of pregnancies affected by severe early-onset fetal growth restriction. The study recruits women with singleton pregnancies where the estimated fetal weight is less than the 3rd centile and below 600 g, between 20 + 0 and 26 + 6 weeks of pregnancy, in the absence of a known chromosomal, structural or infective cause.

Method

The reported study was retrospective descriptive qualitative interview study of women who had participated in the EVERREST Prospective Study. The aim of this study was to explore the experiences and perceptions of pregnant women taking part in research during a pregnancy affected by severe early-onset fetal growth restriction. Audio-recorded semi-structured telephone interviews were conducted with a purposive sample of 12 women, at least 1 year after delivery of their baby. Two of these pregnancies had ended in stillbirth and one in neonatal death, reflecting the outcomes seen in the EVERREST Prospective Study. Participants gave informed consent, were 16 years or older and were interviewed in English. A topic guide was used to ensure a consistent approach. Questions focused on pregnancy experiences, involvement with the EVERREST study and potential involvement in future research. Recordings were transcribed verbatim for thematic analysis using NVivo10.

Results

Four broad themes were identified; ‘before joining the EVERREST Prospective Study’, ‘participating in research’, ‘information and support’ and ‘looking back and looking forwards’. Each broad theme incorporated several subthemes. All participants recalled their reaction to being told their baby was smaller than expected. The way this news was given had a lasting impact. A range of benefits of participation in the EVERREST Prospective Study were described and the participants were positive about the way it was conducted. As a consequence, they were receptive to participating in future research. However, the findings suggest that research teams should be sensitive when approaching families at a difficult time or when they are already participating in other research.

Conclusions

This study highlights the willingness of pregnant women to participate in research and identifies strategies for researchers to engage participants.

A key for perinatal depression early diagnosis: The body dissatisfaction

OBJECTIVE

To test if the evaluation of body dissatisfaction by images could be an interesting tool to detect perinatal depression early in pregnancy, questioning patients about their body image instead of their depressive symptoms.

METHODS

A sample of 457 women was recruited in a longitudinal study. Three evaluations were performed at the 4th and 8th months of pregnancy and during post-partum. During these evaluations, sociodemographic data were collected and psychiatric scales were completed, including Edinburgh Postnatal Depression Scale (EPDS), Eating Disorder Examination-Questionnaire (EDE-Q), Pictorial Body Image Scale (PBIS) and Body Shape Questionnaire (BSQ).

RESULTS

33% of the women who were unsatisfied with their body image suffered from perinatal depression vs. 11.3% of the women who were not (p < 0.0001). The risk of perinatal depression was 4 times higher in women dissatisfied with their body image (p < 0.001) if unintended pregnancy and age are taken into account and is 3 times significantly higher in women with higher levels of eating disorders symptoms (p < 0.001) if unintended pregnancy and age are taken into account. Our sample was a privileged population, as often in the literature.

CONCLUSION

The administration of a simple scale (PBIS) during an early visit during pregnancy allows detecting perinatal depression. This should prevent the stigmatization of women during pregnancy and reduce the risk of not diagnosing depression during pregnancy and post-partum.
