Effectiveness of interpersonal psychotherapy in comparison to other psychological and pharmacological interventions for reducing depressive symptoms in women diagnosed with postpartum depression in low- and middle-income countries: A systematic review

Background

Postpartum depression (PPD) is a condition that can affect any woman regardless of ethnicity, age, party, marital status, income, and type of delivery. This condition is highly prevalent worldwide. PPD, if not treated timely, can affect the maternal-child bond and can have a detrimental impact on the future cognitive, emotional, and behavioral development of the child. Interpersonal psychotherapy (IPT) has been reported as an effective treatment of PPD in previous studies as this focuses on relationship and social support issues. Previous reviews conducted in developed nations have reported the superior efficacy of IPT in comparison to other treatment options. There is no systematic review conducted in low to middle-income countries on the efficacy of IPT on PPD. Therefore it was necessary to undertake a systematic review to assess the effectiveness of IPT in reducing the depression among postpartum women in low and middle-income countries (LMICs).

Objectives

The main aim of this systematic review was to assess the effectiveness of IPT alone or in conjunction with pharmacological therapy and/or other psychological and psychosocial interventions, in reducing depressive symptoms among women diagnosed with PPD residing in LMICs.

Search Methods

The systematic search encompassed several prominent databases and grey literature. Furthermore, experts specializing in the field of IPT were consulted to identify any relevant studies conducted in LMICs that fulfilled the predetermined eligibility criteria. The most recent search update was performed in July 2022.

Selection Criteria

The PICOS criteria were meticulously defined for this review as described. Participants: Postpartum women diagnosed with PPD in LMICs were included. Intervention: IPT either as a standalone treatment or in conjunction with pharmacological therapy was included. Comparison: any form of psychological therapy or pharmacological therapy, whether administered individually or in combination, was considered for comparison. Study designs: experimental and quasi-experimental, factorial designs, and quantitative components (experimental, quasi-experimental, factorial designs) of mixed methods designs were eligible to be included. Studies with single-group study designs and qualitative studies were excluded from the review.

Data Collection and Analysis

Two reviewers from our team conducted a rigorous screening process to determine the eligibility of articles for inclusion. This involved an initial evaluation of titles and abstracts, followed by a comprehensive assessment of the full text of selected articles. In instances where discrepancies arose between the two reviewers, resolution was achieved through discussion or consultation with a third author to establish a consensus. Following the screening process, two team members independently extracted pertinent information and data from the studies that met the inclusion criteria. The treatment effect of the intervention, in comparison to the control group, was subsequently analyzed utilizing the fixed effects model taking into account the small number of studies.

Main Results

A total of 17,588 studies were identified from various databases, and 6493 duplicate studies were removed. Subsequently, 9380 studies underwent independent title and abstract screening resulting in the exclusion of 9040 studies. 345 full texts were thoroughly assessed leading to the exclusion of 341 studies, finally including 4 studies for review. The four included trials were randomized trials and comprised a total sample size of 188 women diagnosed with PPD residing in LMICs. Among these studies, three compared IPT with usual treatment, while one study compared IPT with antidepressant medications (ADMs). In terms of the providers of IPT, in one study, IPT was administered by nurses, while psychologists delivered IPT in another study. In one study, community health workers were responsible for providing IPT. However, in one study, information regarding the specific providers of IPT was not available or reported. The primary outcome measure reported in all four studies was depression, assessed using the Edinburgh Postnatal Depression Scale (EPDS). The geographical distribution of the studies included; one conducted in Zambia, one in Kenya, one in Pakistan, and one in Iran. Out of the four studies, three were included in the meta-analysis, as missing data from one study could not be obtained. Based on the overall treatment effect, it was found that depression scores decreased significantly more in the IPT group compared to other interventions (usual treatment or ADMs) (standardized mean difference [SMD] -0.62, 95% confidence interval [CI] (-1.01, -0.23), Z = 3.13 (p = 0.002), χ 2 = 49.49; df = 2; p < 0.00001; I 2 = 96%; 3 studies, n = 136). Out of the three studies, two studies compared the effectiveness of IPT in reducing depression scores specifically when compared to the usual treatment, and in both studies, depression scores were reduced significantly in the IPT group as compared to the usual treatment group. Only one study directly compared the effectiveness of IPT with ADM, reporting that IPT was more effective than ADM in reducing depression scores among postpartum women. Regarding adverse outcomes, only one study reported suicidal ideation with one participant in the IPT group and two in the ADM group (RR 0.50, 95% CI (0.05, 5.30), p = 0.56, n = 78). The same study reported seven participants in the ADM group had adverse drug reactions as compared to none in the IPT group (RR 15.0, 95% CI (0.89, 254), p = 0.06, n = 78).

Authors' Conclusions

Our comprehensive search yielded a limited number of four studies conducted in such settings. Despite the scarcity of available evidence, the findings collectively suggest that IPT is indeed an effective treatment for reducing PPD when compared to usual treatment and pharmacological therapy. However given the low certainty of evidence, there is a need for further research in the form of well-designed randomized controlled trials with larger sample sizes and a reduced risk of bias. Such studies would greatly contribute to enhancing the strength and reliability of the evidence base regarding the effectiveness of IPT in the context of PPD in LMICs. The knowledge generated from future research endeavors would be highly valuable in guiding the development of more affordable and cost-effective treatment approaches for PPD in resource-limited settings.

Feasibility and Acceptability of Internet-based Interpersonal Psychotherapy for Stress, Anxiety, and Depression in Prenatal Women: Thematic Analysis Abstract (Preprint)

Background

Prenatal mental health is a global health concern. Despite the far-reaching impact of prenatal mental health issues, many women do not receive the psychological care they require. Women in their childbearing years are frequent users of the internet and smartphone apps. Prenatal women are prime candidates for internet-based support for mental health care.

Objective

This study aimed to examine the feasibility and acceptability of internet-based interpersonal psychotherapy (IPT) for prenatal women.

Methods

Semistructured interviews were conducted with women who had received internet-based IPT modules with guided support as a component of a randomized controlled trial evaluating the scale-up implementation of a digital mental health platform (The Healthy Outcomes of Pregnancy and Postpartum Experiences digital platform) for pregnant women. Qualitative thematic analysis was used to explore and describe women’s experiences. Data were analyzed for emerging themes, which were identified and coded.

Results

A total of 15 prenatal women were interviewed to examine their experiences and views on the feasibility and acceptability of internet-based IPT modules. Participants found the content informative and appreciated the ways in which the digital mental health platform made the IPT modules accessible to users. Participants voiced some differing requirements regarding the depth and the way information was presented and accessed on the digital mental health platform. The important areas for improvement that were identified were acknowledging greater depth and clarity of content, the need for sociability and relationships, and refinement of the digital mental health platform to a smartphone app.

Conclusions

This study provides useful evidence regarding treatment format and content preferences, which may inform future development. It also provides research data on the feasibility and acceptability of web-based applications for prenatal mental health care.

Interpersonal Psychotherapy to Reduce Psychological Distress in Perinatal Women: A Systematic Review

BACKGROUND

Interpersonal psychotherapy (IPT) is a psychological intervention with established efficacy in the prevention and treatment of depressive disorders. Previous systematic reviews have not evaluated the effectiveness of IPT on symptoms of stress, anxiety, depression, quality of life, relationship satisfaction/quality, social supports, and an improved psychological sense of wellbeing. There is limited information regarding moderating and mediating factors that impact the effectiveness of IPT such as the timing of the intervention or the mode of delivery of IPT intervention. The overall objective of this systematic review was to evaluate the effectiveness of IPT interventions to treat perinatal (from pregnancy up to 12 months postpartum) psychological distress.

METHODS

MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily (Ovid), EMBASE (Ovid), PsycINFO (Ovid), Cochrane Central Register of Controlled Trials (OVID), CINAHL with Full Text (Ebsco), Social Work Abstracts (Ebsco), SocINDEX with Full Text (Ebsco), Academic Search Complete (Ebsco), Family & Society Studies Worldwide (Ebsco), Family Studies Abstracts (Ebsco), and Scopus databases were searched from inception until 31 January 2019. Two researchers independently screened articles for eligibility. Of the 685 screened articles, 43 met the inclusion criteria. The search was re-run on 11 May 2020. An additional 204 articles were screened and two met the inclusion criteria, resulting in a total of 45 studies included in this review. There were 25 Randomized Controlled Trials, 10 Quasi-experimental studies, eight Open Trials, and two Single Case Studies. All included studies were critically appraised for quality.

RESULTS

In most studies (n = 24, 53%), the IPT intervention was delivered individually; in 17 (38%) studies IPT was delivered in a group setting and two (4%) studies delivered the intervention as a combination of group and individual IPT. Most interventions were initiated during pregnancy (n = 27, 60%), with the remaining 18 (40%) studies initiating interventions during the postpartum period.

LIMITATIONS

This review included only English-language articles and peer-reviewed literature. It excluded government reports, dissertations, conference papers, and reviews. This limited the access to grassroots or community-based recruitment and retention strategies that may have been used to target smaller or marginalized groups of perinatal women.

CONCLUSIONS

IPT is an effective intervention for the prevention and treatment of psychological distress in women during their pregnancy and postpartum period. As a treatment intervention, IPT is effective in significantly reducing symptoms of depression and anxiety as well as improving social support, relationship quality/satisfaction, and adjustment.

Internet-based interpersonal psychotherapy for stress, anxiety, and depression in prenatal women: study protocol for a pilot randomized controlled trial

BACKGROUND

Psychological distress, defined as depression, anxiety and perceived stress, during pregnancy is common, with 15-25% of women experiencing clinically significant levels of such distress. Despite the far-reaching impact of prenatal psychological distress on mothers and their children, and that women are receptive to screening, few providers routinely screen for prenatal psychological distress and less than one in five women will receive the mental health care that they require. There is a lack of certainty regarding the most effective treatments for prenatal psychological distress. No online interpersonal psychotherapy (IPT) trials have been conducted that focus on improving psychological distress in prenatal women. The purpose of this pilot randomized controlled trial is to evaluate the perspectives of pregnant women on the feasibility and acceptability of online IPT (e-IPT) delivered during pregnancy.

METHODS

A pilot randomized controlled trial design with repeated measures will evaluate the feasibility and acceptability of e-IPT for pregnant women compared to routine prenatal care. Qualitative interviews with 15-30 individuals in the intervention group will provide further data on the feasibility and acceptability of the intervention. Assessment of feasibility will include the ease of accessing and completing the intervention. Women will also be asked about what barriers there were to starting and completing the e-IPT. Assessment of acceptability will inquire about the perception of women regarding the intervention and its various features. A sample size of 160 consenting pregnant women aged 18 years and older will be enrolled and randomized into the experimental (e-IPT) or control (routine care) condition. The secondary outcome measures include: depression, anxiety and stress symptoms; self-efficacy; self-mastery; self-esteem; relationship quality (spouse, immediate family members); coping; and resilience. All participants will complete the aforementioned measures at baseline during pregnancy (T1), 3 months postrandomization (T2), at 8 months of pregnancy (T3), and 3 months postpartum (T4).

DISCUSSION

The results of this pilot randomized controlled trial will provide data on the feasibility and acceptability of the intervention and identify necessary adaptations. This study will allow for optimization of full trial processes and inform the evaluation strategy, including sample size calculations for the full randomized controlled trial.

Interpersonal psychotherapy for perinatal women: a systematic review and meta-analysis protocol

BACKGROUND

Interpersonal psychotherapy (IPT) is an intervention that has established efficacy in the prevention and treatment of depressive disorders. Previous systematic reviews have not evaluated the effectiveness of IPT on symptoms of stress, anxiety, depression, quality of life, relationship satisfaction/quality, social supports, and an improved psychological sense of well-being. There is limited data regarding factors that moderate and mediate the effectiveness of IPT including the timing of the intervention or the mode of delivery of IPT intervention. The objective of this systematic review and meta-analysis is to evaluate the effectiveness, feasibility, and acceptability of IPT interventions to treat perinatal psychological distress and to summarize the evidence on predictors, mediators, and moderators of IPT.

METHODS

We will include peer-reviewed studies that recruited perinatal women. The search strategy will involve the following databases: MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), Cochrane Central Register of Controlled Trials (Ovid), CINAHL with Full Text (EBSCO), Social Work Abstracts (EBSCO), SocINDEX with Full Text (EBSCO), Academic Search Complete (EBSCO), Family & Society Studies Worldwide (EBSCO), Family Studies Abstracts (EBSCO), and Scopus. Study inclusion criteria include (1) randomized controlled trials, quasi-experimental studies, and pre-post studies that evaluated the effectiveness of IPT; (2) qualitative studies that evaluated feasibility and acceptability of IPT; (3) study sample included and analyzed perinatal women; and (4) publication language was English. Using pilot-tested screening and data extraction forms, two reviewers will independently review studies in three steps: (1) abstract/title screening, (2) full-text screening of potentially accepted studies, and (3) data extraction of accepted studies. Disagreements will be resolved by a third reviewer. Studies will be aggregated for meta-synthesis and meta-analysis should the data allow for this. Two independent reviewers will grade methodological quality.

DISCUSSION

Findings from this review will inform future development and implementation of IPT intervention research for perinatal women. Identifying key factors of successful IPT interventions will inform intervention design and adaptation of IPT interventions to increase the likelihood that perinatal women will engage in and benefit from IPT interventions. This review will also identify key considerations for increasing the effectiveness of IPT interventions during the perinatal period.

Parental perception of child vulnerability and parental competence: The role of postnatal depression and parental stress in fathers and mothers

Introduction

Parents' perception that their child may be vulnerable to serious life-threatening illnesses can have negative effects on how they exercise their parenting. No studies have yet been carried out on parent´s perception of their child’s vulnerability, when the child has not suffered a severe illness. This study tries to analyze the relationship between parent´s perception of their children´s vulnerability and parental competence, and analyzes the mediating role of postnatal depression and parental stress.

Method

The study was carried out on mothers and fathers of full-term infants who did not have any serious illnesses. A total of 965 people (385 fathers and 580 mothers) participated in the study.

Results

The results revealed an association between parental perception of their child’s vulnerability and parent’s perception of parental competence through depression and parental stress. However, this association was different for fathers and mothers.

Conclusion

The variable of perception of child’s vulnerability was a relevant factor to understand parental competence.

Using sertraline in postpartum and breastfeeding: balancing risks and benefits

INTRODUCTION

The World Health Organization recommends newborns to be breastfed but this may be challenging if the mother needs to be treated for depression, since strong evidence to inform treatment choice is missing.

AREAS COVERED

We provide a critical review of the literature to guide clinicians who are considering sertraline for the management of depression during postpartum.

EXPERT OPINION

Sertraline is one of the safest antidepressants during breastfeeding. In most cases, women already taking sertraline should be advised to breastfeed and continue the medication. We recommend to begin with low doses and to slowly increase the dose up, with careful monitoring of the newborn for adverse effects (irritability, poor feeding, or uneasy sleep, especially if the child was born premature or had low weight at birth). The target dose should be the lowest effective. When feasible, child exposure to the medication may be reduced by avoiding breastfeeding at the time when the antidepressant milk concentration is at its peak. A decision to switch to sertraline from ongoing and effective treatment should be taken only after a scrupulous evaluation of the potential risks and benefits of switching versus continuing the ongoing medication while monitoring the infant carefully.

A pilot randomized controlled trial of a depression and disease management program delivered by phone

BACKGROUND

Depression in medically ill patients occurs at twice the rate found in the general population. Though pharmacologic and psychotherapeutic interventions for depression are effective, response to treatment and access to care are barriers for this population. A multidimensional telehealth intervention was designed to focus on these barriers by delivering a phone based intervention that addressed managing one's illness and coping emotionally.

METHODS

Veterans with diabetes, hypertension, or chronic pain and depressive symptoms were randomized to one of three conditions: Usual Care (n=23), Illness Management Only (n=31), or Combined Psychotherapy and Illness Management (n=29). Those randomized to the Combined or Illness Management Only intervention group received 10 phone visits. Veterans in the Combined group received all aspects of the illness management program plus a manualized depression intervention. Subjects completed assessments at baseline, week 5, and 10 to test the main hypothesis that veterans in the Combined condition would have a greater decline in depressive symptoms.

RESULTS

The Combined intervention yielded a significant decline in depressive symptoms when compared with Usual Care. However, the there was no significant difference between the Combined and Illness Management Only groups.

LIMITATIONS

This is a pilot study with a small sample size relative to a standard randomized controlled trial in psychotherapy.

CONCLUSIONS

This telephone-based intervention succeeded in reducing depressive symptoms in veterans with chronic illness. It adds to the building evidence base for providing phone-delivered mental health services.

Effects of a brief psychoanalytic intervention for perinatal depression

This pilot study explores the effects of a brief individual psychoanalytic therapy on perinatal depressive symptoms. This intervention is based on the Geneva's mother-infant intervention model. A sample of 129 pregnant women was recruited in Geneva (Switzerland) and screened for depressive symptoms with two instruments: the 'Edinburgh postnatal depression scale' (EPDS) and the 'Dépistage anténatal de la dépression postnatale'. A group of 40 women presenting depressive symptoms (treatment group) participated in a four-session intervention called 'Psychotherapy centred on parenthood (PCP)'. It consists in two antenatal and two postnatal sessions and is focussed on changing problematic representations of parenthood. This treatment group was compared to a control group of 88 women without depressive symptoms and following the usual obstetrical care. The main outcome measure was EPDS at 3 and 6 months after delivery. The 'Global assessment functioning scale' was administered at the end of each therapeutic session. The 'Parent-infant relationship global assessment scale' was administered at the two postnatal sessions in order to explore if PCP was also effective in preventing the potential negative effects of depression on mother-infant relationship. Results show that in the treatment group (N = 31), EPDS scores dropped from 12.8 to 4.8; none of these women met the EPDS cut-off score of 12 at 3 and 6 months postpartum. Mother-infant relationship was well adapted for all 31 dyads at the end of the intervention. These results suggest that PCP is a promising intervention for treating perinatal depression and helping mothers engaging in parenting.

Postpartum depression: an essential overview for the practitioner

Postpartum depression (PPD) is a cross-cultural form of major depressive disorder that affects some 13% of women and can have serious health consequences for both the mother and her child. Easy-to-use, reliable, self-administered screening tools are available. PPD may have a variety of etiologies, which include changing plasma levels of estrogen and progesterone, postpartum hypothyroidism, sleep deprivation, or difficult life circumstances. Standard treatments for PPD include psychotherapy and antidepressants. However, treatment of a thyroid condition or insomnia, or even regular exercise or massage may also be beneficial. PPD is underdiagnosed, therefore more screening is needed. Obstetricians and pediatricians have a unique opportunity to test women for PPD, but general practitioners may encounter patients with undiagnosed PPD, too. These physicians could positively impact the lives of depressed mothers and their children by identifying them, then treating or providing referrals for care as appropriate.
