Psychosocial and psychological interventions for treating postpartum depression

Interventions (other than pharmacological, psychosocial or psychological) for treating antenatal depression

BACKGROUND

A meta-analysis of 21 studies suggests the mean prevalence rate for depression across the antenatal period is 10.7%, ranging from 7.4% in the first trimester to a high of 12.8% in the second trimester. Due to maternal treatment preferences and potential concerns about fetal and infant health outcomes, diverse non-pharmacological treatment options are needed.

OBJECTIVES

To assess the effect of interventions other than pharmacological, psychosocial, or psychological interventions compared with usual antepartum care in the treatment of antenatal depression.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2013), scanned secondary references and contacted experts in the field to identify other published or unpublished trials.

SELECTION CRITERIA

All published and unpublished randomised controlled trials of acceptable quality evaluating non-pharmacological/psychosocial/psychological interventions to treat antenatal depression.

DATA COLLECTION AND ANALYSIS

Both review authors participated in the evaluation of methodological quality and data extraction. Results are presented using risk ratio (RR) for categorical data and mean difference (MD) for continuous data.

MAIN RESULTS

Six trials were included involving 402 women from the United States, Switzerland, and Taiwan. For most comparisons a single trial contributed data and there were few statistically significant differences between control and intervention groups.In a trial with 38 women maternal massage compared with non-specific acupuncture (control group) did not significantly decrease the number of women with clinical depression or depressive symptomatology immediately post-treatment (risk ratio (RR) 0.80, 95% confidence interval (CI) 0.25 to 2.53; mean difference (MD) -2.30, 95% CI -6.51 to 1.91 respectively). In another trial with 88 women there was no difference in treatment response or depression remission rates in women receiving maternal massage compared with those receiving non-specific acupuncture (RR 1.33, 95% CI 0.82 to 2.18; RR 1.14, 95% CI 0.59 to 2.19 respectively).In a trial with 35 women acupuncture specifically treating symptoms of depression, compared with non-specific acupuncture, did not significantly decrease the number of women with clinical depression or depressive symptomatology immediately post-treatment (RR 0.47, 95% CI 0.11 to 2.13; MD -3.00, 95% CI -8.10 to 2.10). However, women who received depression-specific acupuncture were more likely to respond to treatment compared with those receiving non-specific acupuncture (RR 1.68, 95% CI 1.06 to 2.66).In a trial with 149 women, maternal massage by a woman's significant other, compared with standard care, significantly decreased the number of women with depressive symptomatology immediately post-treatment (MD -6.70, 95% CI -9.77 to -3.63). Further, women receiving bright light therapy had a significantly greater change in their mean depression scores over the five weeks of treatment than those receiving a dim light placebo (one trial, n = 27; MD -4.80, 95% CI -8.39 to -1.21). However, they were not more likely to have a treatment response or experience a higher remission rate (RR 1.79, 95% CI 0.90 to 3.56; RR 1.89, 95% CI 0.81 to 4.42).Lastly, two trials examined the treatment effect of omega-3 oils. Women receiving omega-3 had a significantly lower mean depression score following eight weeks of treatment than those receiving a placebo (one trial, n = 33; MD -4.70, 95% CI -7.82 to -1.58). Conversely, in a smaller trial (21 women) there was no significant difference in the change in mean depression scores for women receiving omega-3 and those receiving a placebo (MD 0.36, 95% CI -0.17 to 0.89), and women who received omega-3 were no more likely to respond to treatment (RR 2.26, 95% CI 0.78 to 6.49) or have higher remission rates (RR 2.12, 95% CI 0.51 to 8.84). Women in the placebo group were just as likely to report a side effect as those in the omega-3 group (RR 1.12, 95% CI 0.56 to 2.27).

AUTHORS' CONCLUSIONS

The evidence is inconclusive to allow us to make any recommendations for depression-specific acupuncture, maternal massage, bright light therapy, and omega-3 fatty acids for the treatment of antenatal depression. The included trials were too small with non-generalisable samples, to make any recommendations.

Psychosocial and psychological interventions for preventing postpartum depression

BACKGROUND

Epidemiological studies and meta-analyses of predictive studies have consistently demonstrated the importance of psychosocial and psychological variables as postpartum depression risk factors. While interventions based on these variables may be effective treatment strategies, theoretically they may also be used in pregnancy and the early postpartum period to prevent postpartum depression.

OBJECTIVES

Primary: to assess the effect of diverse psychosocial and psychological interventions compared with usual antepartum, intrapartum, or postpartum care to reduce the risk of developing postpartum depression. Secondary: to examine (1) the effectiveness of specific types of psychosocial and psychological interventions, (2) the effectiveness of professionally-based versus lay-based interventions, (3) the effectiveness of individually-based versus group-based interventions, (4) the effects of intervention onset and duration, and (5) whether interventions are more effective in women selected with specific risk factors.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2011), scanned secondary references and contacted experts in the field. We updated the search on 31 December 2012 and added the results to the awaiting classification section of the review for assessment at the next update.

SELECTION CRITERIA

All published and unpublished randomised controlled trials of acceptable quality comparing a psychosocial or psychological intervention with usual antenatal, intrapartum, or postpartum care.

DATA COLLECTION AND ANALYSIS

Review authors and a research co-ordinator with Cochrane review experience participated in the evaluation of methodological quality and data extraction. Additional information was sought from several trial researchers. Results are presented using risk ratio (RR) for categorical data and mean difference (MD) for continuous data.

MAIN RESULTS

Twenty-eight trials, involving almost 17,000 women, contributed data to the review. Overall, women who received a psychosocial or psychological intervention were significantly less likely to develop postpartum depression compared with those receiving standard care (average RR 0.78, 95% confidence interval (CI) 0.66 to 0.93; 20 trials, 14,727 women). Several promising interventions include: (1) the provision of intensive, individualised postpartum home visits provided by public health nurses or midwives (RR 0.56, 95% CI 0.43 to 0.73; two trials, 1262 women); (2) lay (peer)-based telephone support (RR 0.54, 95% CI 0.38 to 0.77; one trial, 612 women); and (3) interpersonal psychotherapy (standardised mean difference -0.27, 95% CI -0.52 to -0.01; five trials, 366 women). Professional- and lay-based interventions were both effective in reducing the risk to develop depressive symptomatology. Individually-based interventions reduced depressive symptomatology at final assessment (RR 0.75, 95% CI 0.61 to 0.92; 14 trials, 12,914 women) as did multiple-contact interventions (RR 0.78, 95% CI 0.66 to 0.93; 16 trials, 11,850 women). Interventions that were initiated in the postpartum period also significantly reduced the risk to develop depressive symptomatology (RR 0.73, 95% CI 0.59 to 0.90; 12 trials, 12,786 women). Identifying mothers 'at-risk' assisted the prevention of postpartum depression (RR 0.66, 95% CI 0.50 to 0.88; eight trials, 1853 women).

AUTHORS' CONCLUSIONS

Overall, psychosocial and psychological interventions significantly reduce the number of women who develop postpartum depression. Promising interventions include the provision of intensive, professionally-based postpartum home visits, telephone-based peer support, and interpersonal psychotherapy.

Psychological therapies for the treatment of post-traumatic stress disorder in children and adolescents

BACKGROUND

Post-traumatic stress disorder (PTSD) is highly prevalent in children and adolescents who have experienced trauma and has high personal and health costs. Although a wide range of psychological therapies have been used in the treatment of PTSD there are no systematic reviews of these therapies in children and adolescents.

OBJECTIVES

To examine the effectiveness of psychological therapies in treating children and adolescents who have been diagnosed with PTSD.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to December 2011. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: CENTRAL (the Cochrane Central Register of Controlled Trials) (all years), EMBASE (1974 -), MEDLINE (1950 -) and PsycINFO (1967 -). We also checked reference lists of relevant studies and reviews. We applied no date or language restrictions.

SELECTION CRITERIA

All randomised controlled trials of psychological therapies compared to a control, pharmacological therapy or other treatments in children or adolescents exposed to a traumatic event or diagnosed with PTSD.

DATA COLLECTION AND ANALYSIS

Two members of the review group independently extracted data. If differences were identified, they were resolved by consensus, or referral to the review team.We calculated the odds ratio (OR) for binary outcomes, the standardised mean difference (SMD) for continuous outcomes, and 95% confidence intervals (CI) for both, using a fixed-effect model. If heterogeneity was found we used a random-effects model.

MAIN RESULTS

Fourteen studies including 758 participants were included in this review. The types of trauma participants had been exposed to included sexual abuse, civil violence, natural disaster, domestic violence and motor vehicle accidents. Most participants were clients of a trauma-related support service.The psychological therapies used in these studies were cognitive behavioural therapy (CBT), exposure-based, psychodynamic, narrative, supportive counselling, and eye movement desensitisation and reprocessing (EMDR). Most compared a psychological therapy to a control group. No study compared psychological therapies to pharmacological therapies alone or as an adjunct to a psychological therapy.Across all psychological therapies, improvement was significantly better (three studies, n = 80, OR 4.21, 95% CI 1.12 to 15.85) and symptoms of PTSD (seven studies, n = 271, SMD -0.90, 95% CI -1.24 to -0.42), anxiety (three studies, n = 91, SMD -0.57, 95% CI -1.00 to -0.13) and depression (five studies, n = 156, SMD -0.74, 95% CI -1.11 to -0.36) were significantly lower within a month of completing psychological therapy compared to a control group.The psychological therapy for which there was the best evidence of effectiveness was CBT. Improvement was significantly better for up to a year following treatment (up to one month: two studies, n = 49, OR 8.64, 95% CI 2.01 to 37.14; up to one year: one study, n = 25, OR 8.00, 95% CI 1.21 to 52.69). PTSD symptom scores were also significantly lower for up to one year (up to one month: three studies, n = 98, SMD -1.34, 95% CI -1.79 to -0.89; up to one year: one study, n = 36, SMD -0.73, 95% CI -1.44 to -0.01), and depression scores were lower for up to a month (three studies, n = 98, SMD -0.80, 95% CI -1.47 to -0.13) in the CBT group compared to a control. No adverse effects were identified.No study was rated as a high risk for selection or detection bias but a minority were rated as a high risk for attrition, reporting and other bias. Most included studies were rated as an unclear risk for selection, detection and attrition bias.

AUTHORS' CONCLUSIONS

There is evidence for the effectiveness of psychological therapies, particularly CBT, for treating PTSD in children and adolescents for up to a month following treatment. At this stage, there is no clear evidence for the effectiveness of one psychological therapy compared to others. There is also not enough evidence to conclude that children and adolescents with particular types of trauma are more or less likely to respond to psychological therapies than others.The findings of this review are limited by the potential for methodological biases, and the small number and generally small size of identified studies. In addition, there was evidence of substantial heterogeneity in some analyses which could not be explained by subgroup or sensitivity analyses.More evidence is required for the effectiveness of all psychological therapies more than one month after treatment. Much more evidence is needed to demonstrate the relative effectiveness of different psychological therapies or the effectiveness of psychological therapies compared to other treatments. More details are required in future trials in regards to the types of trauma that preceded the diagnosis of PTSD and whether the traumas are single event or ongoing. Future studies should also aim to identify the most valid and reliable measures of PTSD symptoms and ensure that all scores, total and sub-scores, are consistently reported.

Web-Based Intervention for Postpartum Depression: Formative Research and Design of the MomMoodBooster Program

Background

Postpartum depression is a significant public health problem affecting approximately 13% of women. There is strong evidence supporting Cognitive Behavioral Therapy (CBT) for successful psychosocial treatment. This treatment model combines cognitive and behavioral strategies to address pessimism, attributions for failure, low self-esteem, low engagement in pleasant activities, social withdrawal, anxiety, and low social support. Encouraging results have been reported for using Web-based CBT interventions for mental health domains, including the treatment of panic disorder, post-traumatic stress disorder, and complicated grief and depression. To date, however, Web-based interventions have not been used and evaluated specifically for the treatment of postpartum depression.

Objective

We describe the formative work that contributed to the development of our Web-based intervention for helping to ameliorate symptoms of postpartum depression, and the design and key components of the program.

Methods

A total of 17 focus group participants and 22 usability testers, who shared key characteristics with the participants of our planned feasibility study, took part.

The proposed structure and ingredients of the program and mock-ups of selected webpages were presented to focus group participants. At various points, participants were asked a series of thought questions designed to elicit opinions and set the occasion for group discussion. At the end of the session, participants were asked to describe their overall reaction to the proposed features of the program emphasizing candid opinions about what they did not like and features they thought were missing and should be added.

Usability testers were asked to interact with a series of seven different Web-based interactions planned for the program while receiving minimal direction. Each tester was asked to describe her thoughts using a think-aloud technique. They were then asked to consider all that they had learned about the program and complete the System Usability Scale that we adapted slightly to be appropriate for evaluating the proposed website.

Transcripts from the focus groups and usability tests were reviewed by research team members for overarching themes with particular emphasis on suggested changes. A list emerged, and iterative and incremental adjustments were made as a result.

Results

The qualitative and quantitative data gathered in the focus groups and usability sessions reported here suggest that the new mothers involved had largely positive reactions to the major features of the program and that those program features performed well in terms of usability.

Conclusions

An overview of the eventual design, architecture, and key program ingredients of the MomMoodBooster program is provided including innovative features supplementing 6 core CBT sessions, which include a partner’s website, a library, and individual feedback by a personal coach.

Examination of a telephone-based exercise intervention for the prevention of postpartum depression: design, methodology, and baseline data from The Healthy Mom study

Research indicates that exercise is an efficacious intervention for depression among adults; however, little is known regarding its efficacy for preventing postpartum depression. The Healthy Mom study was a randomized controlled trial examining the efficacy of an exercise intervention for the prevention of postpartum depression. Specifically, postpartum women with a history of depression or a maternal family history of depression (n=130) were randomly assigned to a telephone-based exercise intervention or a wellness/support contact control condition each lasting six months. The exercise intervention was designed to motivate postpartum women to exercise based on Social Cognitive Theory and the Transtheoretical Model. The primary dependent variable was depression based on the Structured Clinical Diagnostic Interview (SCID). Secondary dependent variables included scores on the Edinburgh Postnatal Depression Scale, the PHQ-9, and the Perceived Stress Scale. The purpose of this paper is to describe the study design, methodology, and baseline data for this trial. Upon completion of the trial, the results will yield important information about the efficacy of exercise in preventing postpartum depression.

Use of video feedback intervention in an inpatient perinatal psychiatric setting to improve maternal parenting

This study utilizes video feedback to improve maternal parenting behavior in clinically depressed mothers admitted to a perinatal inpatient psychiatric unit. Depressed mothers (n = 74) were randomized to "video" (n = 25), "verbal" (n = 26), or "standard care" (n = 23). "Video" mothers were taped playing with their infant; interaction was reviewed with a mental health specialist. "Verbal" mothers only discussed interaction with their infant. "Standard care" mothers received only routine inpatient care. Mothers were assessed for mental health status, perceptions of baby behavior, and parenting competence. There was significant improvement in mental health status of all participants, regardless of intervention. Neither intervention had an advantage, compared to standard care, in improving parenting confidence or perceptions of infant behavior. Video mothers were more likely to report no change in their parenting confidence the more feedback sessions completed. The number of intervention sessions for each participant was limited by the duration of their inpatient admission. Most participants were on simultaneous pharmacotherapy and psychotherapy, as well as receiving intensive mothercraft assistance; this may have influenced intervention effectiveness. Results suggest that this type of intervention may be beneficial, but in the current format does not add sufficiently to standard care to be detected by the measures used.

The Efficacy of Cognitive Behavioral Therapy: A Review of Meta-analyses

Cognitive behavioral therapy (CBT) refers to a popular therapeutic approach that has been applied to a variety of problems. The goal of this review was to provide a comprehensive survey of meta-analyses examining the efficacy of CBT. We identified 269 meta-analytic studies and reviewed of those a representative sample of 106 meta-analyses examining CBT for the following problems: substance use disorder, schizophrenia and other psychotic disorders, depression and dysthymia, bipolar disorder, anxiety disorders, somatoform disorders, eating disorders, insomnia, personality disorders, anger and aggression, criminal behaviors, general stress, distress due to general medical conditions, chronic pain and fatigue, distress related to pregnancy complications and female hormonal conditions. Additional meta-analytic reviews examined the efficacy of CBT for various problems in children and elderly adults. The strongest support exists for CBT of anxiety disorders, somatoform disorders, bulimia, anger control problems, and general stress. Eleven studies compared response rates between CBT and other treatments or control conditions. CBT showed higher response rates than the comparison conditions in 7 of these reviews and only one review reported that CBT had lower response rates than comparison treatments. In general, the evidence-base of CBT is very strong. However, additional research is needed to examine the efficacy of CBT for randomized-controlled studies. Moreover, except for children and elderly populations, no meta-analytic studies of CBT have been reported on specific subgroups, such as ethnic minorities and low income samples.

Recognizing and treating peripartum depression

BACKGROUND

In this article, we review current data on the prevalence of, risk factors for, and treatment of peripartum depression.

METHOD

Pertinent publications were retrieved by searches in Medline and the Cochrane Library using the key words "peri/pre/post", "partum/partal/natal", "maternal/motherhood/pregnancy", and "depression/affective disorder".

RESULTS

Depression is the most common peripartal disease: The prevalence of depressive disorders is 18.4% during pregnancy and 19.2% in the puerperium. Prepartum depression is associated with preterm birth, low birth weight, and an abnormal fetal heart rate. In the long run, children of depressed mothers have been found to have impaired cognitive and emotional abilities. Risk factors for peripartal depression include prior depression, poor social support, poor quality of intimate relationship, and negative live events. Peripartum depression can be treated effectively with psychotherapy or drug therapy. Current data support the use of antidepressants during pregnancy and breastfeeding. In many places, pregnancy counseling centers offer low-threshold psychosocial assistance. Nonetheless, no more than 20% of the affected women are identified, even though rapid screening would be possible with instruments such as the Edinburgh Postnatal Depression Scale (EPDS) and the two Whooley questions.

CONCLUSION

Peripartum depression is both common and treatable. Screening for depression should become a routine part of both prepartum care by gynecologists and postpartum care by midwives. This will only be possible, however, with expanded availability of ambulatory and inpatient psychotherapy and psychiatric care for the affected women and their children.

Impact of a health promotion intervention on maternal depressive symptoms at 15 months postpartum

Given that diet, physical activity, and social support are associated with depression, we examined whether a health promotion intervention designed to modify these factors in low-income, postpartum women would reduce depressive symptoms. This study used a randomized, controlled design to examine the effect of the Just for You (JFY) Program, an educational intervention promoting healthy lifestyles through home visits by nutrition paraprofessionals and motivational telephone counseling, on postpartum depressive symptoms. A total of 679 women income-eligible for the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) were recruited at 6-20 weeks post delivery and randomized to Usual WIC Care or JFY. Using an intention-to-treat analysis, the authors modeled depressive symptoms on the Center for Epidemiologic Studies Depression Scale (CES-D) among 403 women (59%) completing follow-up at a mean of 15 months infant age, adjusting for baseline CES-D, age, household income and randomization strata (body mass index (BMI), race/region). As a secondary analysis, the authors evaluated potential mediators related to social support and self-efficacy to change one or more health behaviors targeted by the intervention. Women randomized to JFY reported 2.5 units lower CES-D score (P = 0.046) compared with those receiving Usual WIC Care alone. This relationship was attenuated by change in self-efficacy (β = -2.3; P = 0.065), suggesting this construct may partially have mediated the effect of JFY on maternal depressive symptoms. A health promotion intervention delivered through home visits and telephone calls can reduce depressive symptoms at 15 months postpartum among low-income, ethnically diverse women.

The effect of telephone-based interpersonal psychotherapy for the treatment of postpartum depression: study protocol for a randomized controlled trial

BACKGROUND

Substantial data indicate potential health consequences of untreated postpartum depression (PPD) on the mother, infant, and family. Studies have evaluated interpersonal psychotherapy (IPT) as treatment for PPD; however, the results are questionable due to methodological limitations. A comprehensive review of maternal treatment preferences suggests that mothers favor 'talking therapy' as a form of PPD treatment. Unfortunately, IPT is not widely available, especially in rural and remote areas. To improve access to care, telepsychiatry has been introduced, including the provision of therapy via the telephone.

METHODS/DESIGN

The purpose of this randomized controlled trial is to evaluate the effect of telephone-based IPT on the treatment of PPD. Stratification is based on self-reported history of depression and province. The target sample is 240 women. Currently, women from across Canada between 2 and 24 weeks postpartum are able to either self-identify as depressed and refer themselves to the trial or they may be referred by a health professional based on a score >12 on the Edinburgh Postnatal Depression Scale (EPDS). Following contact by the trial coordinator, a detailed study explanation is provided. Women who fulfill the eligibility criteria (including a positive diagnostic assessment for major depression) and consent to participate are randomized to either the control group (standard postpartum care) or intervention group (standard postpartum care plus 12 telephone-based IPT sessions within 12 to 16 weeks, provided by trained nurses). Blinded research nurses telephone participants at 12, 24, and 36 weeks post-randomization to assess for PPD and other outcomes including depressive symptomatology, anxiety, couple adjustment, attachment, and health service utilization. Results from this ongoing trial will: (1) develop the body of knowledge concerning the effect of telephone-based IPT as a treatment option for PPD; (2) advance our understanding of training nurses to deliver IPT; (3) provide an economic evaluation of an IPT intervention; (4) investigate the utility of the EPDS in general clinical practice to identify depressed mothers; and (5) present valuable information regarding PPD, along with associated couple adjustment, co-morbid anxiety and self-reported attachment among a mixed rural and urban Canadian population.

Health-related quality of life and post-traumatic stress disorder symptoms in accident and emergency attenders suffering from psychosocial crises: a longitudinal study

Aims

This paper is a report of a study of health-related quality of life and post-traumatic stress disorder symptoms in patients attending an Accident and Emergency department because of psychosocial crises.

Background

Psychosocial crises are commonplace globally, but there is little knowledge about patients attending Accident and Emergency departments because of psychosocial crises.

Methods

Data were collected at an Accident and Emergency department in Norway from September 2008 to June 2009. A total of 99 adults participated in the baseline study and 41 of these participated at 2 months follow-up. The Short Form-36 Health Survey and the Post Traumatic Symptom Scale were used to obtain data.

Findings

Participants reported significantly lower scores in all health-related quality of life domains at baseline compared with the general Norwegian population. The mental health score was two standard deviations below the norm. Health-related quality of life scores were improved and post-traumatic stress disorder symptoms were reduced after 2 months. High levels of post-traumatic stress disorder symptoms were reported by 78% of the participants at baseline and 59% at follow-up. Participants with high levels of post-traumatic stress disorder symptoms at follow-up also reported low health-related quality of life scores.

Conclusion

This study suggests a need for an acute psychosocial intervention and an opportunity to receive follow-up support at Accident and Emergency departments.

Treating postnatal depressive symptoms in primary care: a randomised controlled trial of GP management, with and without adjunctive counselling

BACKGROUND

Postnatal depression (PND) is under-diagnosed and most women do not access effective help. We aimed to evaluate comparative management of (PND) following screening with the Edinburgh Postnatal Depression Scale, using three best-practice care pathways by comparing management by general practitioners (GPs) alone compared to adjunctive counselling, based on cognitive behavioural therapy (CBT), delivered by postnatal nurses or psychologists.

METHODS

This was a parallel, three-group randomised controlled trial conducted in a primary care setting (general practices and maternal & child health centres) and a psychology clinic. A total of 3,531 postnatal women were screened for symptoms of depression; 333 scored above cut-off on the screening tool and 169 were referred to the study. Sixty-eight of these women were randomised between the three treatment groups.

RESULTS

Mean scores on the Beck Depression Inventory (BDI-II) at entry were in the moderate-to-severe range. There was significant variation in the post-study frequency of scores exceeding the threshold indicative of mild-to-severe depressive symptoms, such that more women receiving only GP management remained above the cut-off score after treatment (p = .028). However, all three treatment conditions were accompanied by significant reductions in depressive symptoms and mean post-study BDI-II scores were similar between groups. Compliance was high in all three groups. Women rated the treatments as highly effective. Rates of both referral to the study (51%), and subsequent treatment uptake (40%) were low.

CONCLUSIONS

Data from this small study suggest that GP management of PND when augmented by a CBT-counselling package may be successful in reducing depressive symptoms in more patients compared to GP management alone. The relatively low rates of referral and treatment uptake, suggest that help-seeking remains an issue for many women with PND, consistent with previous research.

New insights into perinatal depression: pathogenesis and treatment during pregnancy and postpartum

Maternal perinatal mental health has enormous consequences for the well-being of the mother, her baby, and the family. Although it is well documented that perinatal depression is both common and morbid, with a prevalence of 10% to 15% in the general population, there remain many critically important unanswered questions about the pathogenesis of perinatal depression and most effective treatment regimens. Current lines of evidence from both human and animal models implicate hormonal dysregulation, abnormalities in hypothalamic-pituitary-adrenal axis activity, and the contributions of genetics and epigenetics as playing key roles in the development of perinatal reproductive mood disorders. Investigations into both human and animal models of perinatal depression offer much promise for the future identification of the underlying pathophysiology and subsequent early identification and/or prevention and appropriate treatment for women at risk for postpartum depression. Lastly, although it is generally accepted that pregnancy is not protective with regard to new onset or relapse of depression, the way to best treat maternal depression during pregnancy and lactation remains hotly debated. Future research in this area will more clearly elucidate the underlying pathogenesis, the potential long-term impact of perinatal depression on the developing fetus, and how best to counsel pregnant women about the risks of untreated major depressive disorder versus the risks of psychopharmacologic treatment during pregnancy and lactation.

Integrating social epidemiology into public health research and practice for maternal depression

The impact of maternal depression on women and their families has been well documented. Given the prevalence and impact of this problem, one important strategy is to strengthen and expand our public health approaches. Although principles of social epidemiology are increasingly used in the field of maternal and child health, few public health efforts to address maternal mental health have incorporated ecosocial frameworks such as community connectedness, quality of social relationships, and social capital. One method to augment current public health approaches to maternal depression is through the incorporation of a perspective focusing on community, cohesion, group membership, and connectedness--a concept often described as social capital. We describe the relevance of this ecosocial perspective for mental health promotion programs for mothers.

A meta-analysis of treatments for perinatal depression

This meta-analysis assessed efficacy of pharmacologic and psychological interventions for treatment of perinatal depression. A systematic review identified 27 studies, including open trials (n=9), quasi-randomized trials (n=2), and randomized controlled trials (n=16) assessing change from pretreatment to posttreatment or comparing these interventions to a control group. Uncontrolled and controlled effect sizes were assessed in separate meta-analyses. There was significant improvement in depressive symptoms from pretreatment to posttreatment, with an uncontrolled overall effect size (Hedges' g) of 1.61 after removal of outliers and correction for publication bias. Symptom levels at posttreatment were below cutoff levels indicative of clinically significant symptoms. At posttreatment, intervention groups demonstrated significantly greater reductions in depressive symptoms compared to control groups, with an overall controlled effect size (Hedges' g) of 0.65 after removal of outliers. Individual psychotherapy was superior to group psychotherapy with regard to changes in symptoms from pretreatment to posttreatment. Interventions including an interpersonal therapy component were found to have greater effect sizes, compared to control conditions, than interventions including a cognitive-behavioral component. Implications of the findings for clinical practice and future research are discussed.

Treatment of postpartum depression: clinical, psychological and pharmacological options

Postpartum depression (PPD) is a common complication of childbearing, and has increasingly been identified as a major public health problem. Untreated maternal depression has multiple potential negative effects on maternal-infant attachment and child development. Screening for depression in the perinatal period is feasible in multiple primary care or obstetric settings, and can help identify depressed mothers earlier. However, there are multiple barriers to appropriate treatment, including concerns about medication effects in breastfeeding infants. This article reviews the literature and recommendations for the treatment of postpartum depression, with a focus on the range of pharmacological, psychotherapeutic, and other nonpharmacologic interventions.

Effectiveness of counseling for anxiety and depression in mothers of children ages 0-30 months by community workers in Karachi, Pakistan: a quasi experimental study

BACKGROUND

The prevalence of anxiety/depression is quite high during the perinatal period but unfortunately its detection and treatment have been less than satisfactory. Moreover, many women are reluctant to take pharmacotherapy for fear of excretion of drugs into their breast milk. This study assesses the effectiveness of counseling from minimally trained community health workers in reducing anxiety/depression, the rate of recurrence and the interval preceding recurrence in women during first two and a half years after childbirth.

METHODS

In a quasi-experimental study, community women from two under-privileged communities were trained in data gathering, teaching healthy child-rearing practices, basic counseling skills, and screening for anxiety/depression by using an indigenously developed questionnaire, the Aga Khan University Anxiety and Depression Scale (AKUADS). The diagnosis was further confirmed by a clinical psychologist using DSM IV criteria. After obtaining consent, 420 women were screened and 102 were identified as having anxiety/depression. Screening was carried out after 1, 2, 6, 12, 18, 24 and 30 months of a live birth. Only 62 out of 102 agreed to be counseled and received eight weekly sessions. AKUADS was re-administered at 4 weeks and 8 weeks after the beginning of counseling; this was followed by the clinical psychologist's interview for confirmation of response. After recovery, screening was continued every 3 months for detection of recurrence throughout the study period. Out of the women who had declined counseling 12 agreed to retake AKUADS after 4 and 8 weeks of diagnosis. Independent samples t-test, chi-square test, Repeated Measures ANOVA and Kaplan Meier technique were used for the analysis.

RESULTS

A significant decline in level of anxiety/depression was found in both the counseled and the non-counseled groups at 4 and 8 weeks (p-value < 0.001) but the counseled group fared better than the non-counseled for recovery, reduction in the rate of recurrence and increase in the duration before relapse.

CONCLUSIONS

As our results cannot be generalized; further studies need to be carried out, to assess the benefit of incorporating minimal counseling skills in the training of community health workers.

The relationship between infant-feeding outcomes and postpartum depression: a qualitative systematic review

CONTEXT

The negative health consequences of postpartum depression are well documented, as are the benefits of breastfeeding. Despite the detailed research related to these maternal and infant health outcomes, the relationship between maternal mood and breastfeeding remains equivocal.

OBJECTIVE

A qualitative systematic review was conducted to examine the relationship between postpartum depressive symptomatology and infant-feeding outcomes.

METHODS

We performed electronic searchers in Medline (1966-2007), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982-2007), and Embase (1980-2007) by using specific key words. A hand search of selected specialist journals and reference lists of articles obtained was then conducted. Seventy-five articles were reviewed, of which 49 specifically provided data to be extracted related to postpartum depressive symptomatology and infant-feeding outcomes. Both authors independently extracted data including study design, participants (number and characteristics), and results.

RESULTS

The results from this review suggest that women with depressive symptomatology in the early postpartum period may be at increased risk for negative infant-feeding outcomes including decreased breastfeeding duration, increased breastfeeding difficulties, and decreased levels of breastfeeding self-efficacy. There is also beginning evidence to suggest that depressed women may be less likely to initiate breastfeeding and do so exclusively.

CONCLUSIONS

Depressive symptomatology in the postpartum period negatively influences infant-feeding outcomes. These findings have important clinical implications and support the need for early identification and treatment of women with depressive symptomatology. However, strategies to address help-seeking barriers are needed if women are to receive appropriate and timely treatment. Research to determine effective interventions to support depressed breastfeeding women is warranted.

Postpartum depression

Postpartum depression (PPD) affects up to 15% of mothers. Recent research has identified several psychosocial and biologic risk factors for PPD. The negative short-term and long-term effects on child development are well-established. PPD is under recognized and under treated. The obstetrician and pediatrician can serve important roles in screening for and treating PPD. Treatment options include psychotherapy and antidepressant medication. Obstacles to compliance with treatment recommendations include access to psychotherapists and concerns of breastfeeding mothers about exposure of the infant to antidepressant medication. Further research is needed to examine systematically the short-term and long-term effect of medication exposure through breastmilk on infant and child development.

A systematic review of home-based interventions to prevent and treat postpartum depression

This systematic review evaluated randomized controlled trials assessing home-based psychological interventions to prevent and treat postpartum depression (PPD). Six studies meeting inclusion criteria were identified, five assessing treatments for PPD and one assessing a preventive intervention for PPD. Interventions used cognitive behavioral, psychodynamic, and non-directive counseling approaches. Of the six studies reviewed, four reported statistically significant treatment effects on PPD following the intervention. Each of the three types of psychological interventions were shown to reduce levels of maternal depression. Recommendations for future development and evaluation of home-based psychological interventions for PPD are discussed. These include identification of mediators and moderators of intervention efficacy, exploring strategies for prevention of PPD, and targeting high-risk groups.

Functional interpretations of sadness, stress and demoralization among an urban population of low-income mothers

OBJECTIVES

We sought to understand how low-income urban mothers explain feelings of sadness, stress or demoralization in the context of their life experiences.

METHODS

28 in-depth qualitative interviews, constituting part of a community-based participatory research (CBPR) project aimed at developing a culturally relevant, community-based intervention for maternal depression. Qualitative data validity was ensured through investigator and expert triangulation, and through member checking.

RESULTS

The following themes emerged: (1) Informants spoke of wanting reprieves from chaos, and discussed this desire relative to wanting to be alone. By contrast, informants expressed loneliness not only in interpersonal terms, but also related to having problems that precluded future relationships, or feeling unique in experiencing an adversity. (2) Informants spoke of demoralization associated with feeling that their problems were externally imposed and therefore beyond their control, but spoke of empowerment associated with owning one's problems. (3) Informants discussed degrees of sadness in relation to their own abilities to adjust or modify their mood, or their ability to contain their feelings.

CONCLUSIONS

Our data suggest that helping a mother find reprieves from chaos, increasing her perception of her own locus of control around externally imposed adversities, and empowering her to recognize and self-manage her own feelings may constitute important elements of a culturally relevant, community-based intervention for depression.

Clinical effectiveness of health visitor training in psychologically informed approaches for depression in postnatal women: pragmatic cluster randomised trial in primary care

OBJECTIVE

To evaluate benefits for postnatal women of two psychologically informed interventions by health visitors.

DESIGN

Prospective cluster trial randomised by general practice, with 18 month follow-up.

SETTING

101 general practices in Trent, England.

PARTICIPANTS

2749 women allocated to intervention, 1335 to control.

INTERVENTION

Health visitors (n=89 63 clusters) were trained to identify depressive symptoms at six to eight weeks postnatally using the Edinburgh postnatal depression scale (EPDS) and clinical assessment and also trained in providing psychologically informed sessions based on cognitive behavioural or person centred principles for an hour a week for eight weeks. Health visitors in the control group (n=49 38 clusters) provided usual care.

MAIN OUTCOME MEASURES

Score >or=12 on the Edinburgh postnatal depression scale at six months. Secondary outcomes were mean Edinburgh postnatal depression scale, clinical outcomes in routine evaluation-outcome measure (CORE-OM), state-trait anxiety inventory (STAI), SF-12, and parenting stress index short form (PSI-SF) scores at six, 12, 18 months.

RESULTS

4084 eligible women consented and 595 women had a six week EPDS score >or=12. Of these, 418 had EPDS scores available at six weeks and six months. At six months, 34% women (93/271) in the intervention group and 46% (67/147) in the control group had an EPDS score >or=12. The odds ratio for score >or=12 at six months was 0.62 (95% confidence interval 0.40 to 0.97, P=0.036) for women in the intervention group compared with women in the control group. After adjustment for covariates, the odds ratio was 0.60 (0.38 to 0.95, P=0.028). At six months, 12.4% (234/1880) of all women in the intervention group and 16.7% (166/995) of all women in the control group had scores >or=12 (0.67, 0.51 to 0.87, P=0.003). Benefit for women in the intervention group with a six week EPDS score >or=12 and for all women was maintained at 12 months postnatally. There was no differential benefit for either psychological approach over the other.

CONCLUSION

Training health visitors to assess women, identify symptoms of postnatal depression, and deliver psychologically informed sessions was clinically effective at six and 12 months postnatally compared with usual care.

Effect of peer support on prevention of postnatal depression among high risk women: multisite randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of telephone based peer support in the prevention of postnatal depression.

DESIGN

Multisite randomised controlled trial.

SETTING

Seven health regions across Ontario, Canada.

PARTICIPANTS

701 women in the first two weeks postpartum identified as high risk for postnatal depression with the Edinburgh postnatal depression scale and randomised with an internet based randomisation service.

INTERVENTION

Proactive individualised telephone based peer (mother to mother) support, initiated within 48-72 hours of randomisation, provided by a volunteer recruited from the community who had previously experienced and recovered from self reported postnatal depression and attended a four hour training session.

MAIN OUTCOME MEASURES

Edinburgh postnatal depression scale, structured clinical interview-depression, state-trait anxiety inventory, UCLA loneliness scale, and use of health services.

RESULTS

After web based screening of 21 470 women, 701 (72%) eligible mothers were recruited. A blinded research nurse followed up more than 85% by telephone, including 613 at 12 weeks and 600 at 24 weeks postpartum. At 12 weeks, 14% (40/297) of women in the intervention group and 25% (78/315) in the control group had an Edinburgh postnatal depression scale score >12 (chi(2)=12.5, P<0.001; number need to treat 8.8, 95% confidence interval 5.9 to 19.6; relative risk reduction 0.46, 95% confidence interval 0.24 to 0.62). There was a positive trend in favour of the intervention group for maternal anxiety but not loneliness or use of health services. For ethical reasons, participants identified with clinical depression at 12 weeks were referred for treatment, resulting in no differences between groups at 24 weeks. Of the 221 women in the intervention group who received and evaluated their experience of peer support, over 80% were satisfied and would recommend this support to a friend.

CONCLUSION

Telephone based peer support can be effective in preventing postnatal depression among women at high risk.
