The optimum way to improve the recognition and treatment of postnatal depression in developing countries is uncertain. We compared the effectiveness of a multicomponent intervention with usual care to treat postnatal depression in low-income mothers in primary-care clinics in Santiago, Chile.
                230 mothers with major depression attending postnatal clinics were randomly allocated to either a multicomponent intervention (n=114) or usual care (n=116). The multicomponent intervention involved a psychoeducational group, treatment adherence support, and pharmacotherapy if needed. Usual care included all services normally available in the clinics, including antidepressant drugs, brief psychotherapeutic interventions, medical consultations, or external referral for specialty treatment. The primary outcome measure was the Edinburgh postnatal depression scale (EPDS) score at 3 and 6 months after randomisation. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00518830.
                208 (90%) of women randomly assigned to treatment groups completed assessments. The crude mean EPDS score was lower for the multicomponent intervention group than for the usual care group at 3 months (8.5 [95% CI 7.2-9.7] vs 12.8 [11.3-14.1]). Although these differences between groups decreased by 6 months, EPDS score remained better in multicomponent intervention group than in usual care group (10.9 [9.6-12.2] vs 12.5 [11.1-13.8]). The adjusted difference in mean EPDS between the two groups at 3 months was -4.5 (95% CI -6.3 to -2.7; p<0.0001). The decrease in the number of women taking antidepressants after 3 months was greater in the intervention group than in the usual care group (multicomponent intervention from 60/101 [59%; 95% CI 49-69%] to 38/106 [36%; 27-46%]; usual care from 18/108 [17%; 10-25%] to 11/102 [11%; 6-19%]).
                Our findings suggest that low-income mothers with depression and who have newly born children could be effectively helped, even in low-income settings, through multicomponent interventions. Further refinements to this intervention are needed to ensure treatment compliance after the acute phase. Psychological interventions for postnatal depression can be beneficial in the short term but their longer-term impact is unknown.
                To evaluate the long-term effect on maternal mood of three psychological treatments in relation to routine primary care.
                Women with post-partum depression (n=193) were assigned randomly to one of four conditions: routine primary care, non-directive counselling, cognitive-behavioural therapy or psychodynamic therapy. They were assessed immediately after the treatment phase (at 4.5 months) and at 9, 18 and 60 months post-partum.
                Compared with the control, all three treatments had a significant impact at 4.5 months on maternal mood (Edinburgh Postnatal Depression Scale, EPDS). Only psychodynamic therapy produced a rate of reduction in depression (Structured Clinical Interview for DSM-III - R) significantly superior to that of the control. The benefit of treatment was no longer apparent by 9 months post-partum. Treatment did not reduce subsequent episodes of post-partum depression.
                Psychological intervention for post-partum depression improves maternal mood (EPDS) in the short term. However, this benefit is not superior to spontaneous remission in the long term. Antenatal depression is a significant risk factor for postpartum depression, with a 10%-12% prevalence in all pregnancies. Rates of depression are higher for pregnant women with chronic stressors, financial and housing problems, and inadequate social support. Despite the prevalence and associated family and infant morbidity, there are no controlled clinical treatment trials regarding this topic, to the authors' knowledge. APA has identified treatment of depression during pregnancy as a priority for clinical guidelines.
                A 16-week bilingual controlled clinical trial compared a group receiving interpersonal psychotherapy for antepartum depression to a parenting education control program. Fifty outpatient antepartum women who met DSM-IV criteria for major depressive disorder were randomly assigned to interpersonal psychotherapy or a didactic parenting education program. Thirty-eight women remained in the study and were included in the data analysis. Depressed mood was measured with the Edinburgh Postnatal Depression Scale, the Beck Depression Inventory, and the Hamilton Depression Rating Scale. The Clinical Global Impression (CGI) and the Hamilton depression scale measured recovery.
                The interpersonal psychotherapy treatment group showed significant improvement compared to the parenting education control program on all three measures of mood at termination. Recovery criteria were met in 60% of the women treated with interpersonal psychotherapy, according to a CGI score of < or = 2. In addition, there was a significant correlation between maternal mood and mother-infant interaction.
                Interpersonal psychotherapy is an effective method of antidepressant treatment during pregnancy and should be a first-line treatment in the hierarchy of treatment for antepartum depression. Social support theory and observational risk factor studies suggest that increased antenatal psychosocial support could prevent post-natal depression. We used empirical knowledge of risk and protective factors for post-natal depression not employed previously in order to develop and evaluate an antenatal preventive intervention.
                We conducted a pragmatic randomized controlled trial in antenatal clinics. We screened 1300 primiparous women and 400 screened positive, 69 screen-positive women were untraceable or not eligible. Of 292 women who completed baseline assessment, 209 consented to randomization, of these 190 provided outcome data 3 months post-natally. 'Preparing for Parenthood', a structured antenatal risk factor reducing intervention designed to increase social support and problem-solving skills, was compared with routine antenatal care only. We compared the percentage depressed at 3 months after childbirth using the self-completion General Health Questionnaire Depression scale and Edinburgh Post-natal Depression Scale (EPDS), and the Schedules for Clinical Assessment in Neuropsychiatry a systematic clinical interview.
                Assignment to the intervention group did not significantly impact on post-natal depression (odds ratio for GHQ-Depression 1.22 (95% CI 0.63-2.39), P = 0.55) or on risk factors for depression. Forty-five per cent of the intervention group women attended sufficient sessions to be likely to benefit from intervention if effective. Attenders benefited no more than non-attenders.
                Prevention services targeting post-natal depression should not implement antenatal support programmes on these lines until further research has demonstrated the feasibility and effectiveness of such methods. The development of novel, low cost interventions effective in reducing risk factors should be completed before further trial evaluation.

                Pregnant women with risk factors for postnatal depression.
                Women attending their first prenatal visit at the Royal Women's Hospital, Brisbane, were screened for risk factors for postnatal depression (IDentify). Positively screened women were randomly allocated to the intervention group or the control group. The intervention consisted of a booklet about postnatal depression, which included contact numbers; prenatal screening using the Edinburgh Postnatal Depression Scale; a discussion with the woman about her risk of developing postnatal depression (Educate); and a letter to the woman's referring general practitioner and local Child Health Nurse, alerting them of the woman's risk for postnatal depression (Alert).
                Edinburgh Postnatal Depression Scale Score > 12 at 16 weeks postpartum.
                Of the 509 women who were sent a follow-up questionnaire, 371 (72.9%) responded. The proportion of women who reported an Edinburgh Postnatal Depression Scale score of >12 was 26%. There were no significant differences between intervention (46/192, 24%) and control groups (50/177, 28.2%) on this primary outcome measure (OR 0.80; 95% CI 0.50-1.28).
                Over one-quarter of women with risk factors will develop postnatal depression. It is a treatable disorder but under-diagnosis is common. Efforts to reduce postnatal depression by implementing interventions in the prenatal period have been unsuccessful. A randomized controlled trial was conducted to evaluate the efficacy of a cognitive-behavioral (CBT) intervention to prevent perinatal depression in high-risk Latinas.
                A sample of 217 participants, predominantly low-income Central American immigrants who met demographic and depression risk criteria, were randomized into usual care (UC; n = 105) or an 8-week CBT group intervention during pregnancy and 3 individual booster sessions during postpartum (n = 112). Participants completed measures assessing depressive symptoms (Center for Epidemiological Studies Depression Scale at baseline; Beck Depression Inventory, Second Edition [BDI-II]) and major depressive episodes (Mood Screener) at 5 time points throughout the perinatal period.
                Intent-to-treat analyses indicated that intervention participants had significantly lower depressive symptoms and fewer cases of moderate depression (BDI-II ≥ 20) at Time 2 than UC participants. These effects were stronger for women who fully participated in the intervention (≥ 4 classes). The cumulative incidence of major depressive episodes was not significantly different between the intervention (7.8%) and UC (9.6%) groups.
                A CBT intervention for low-income, high-risk Latinas reduced depressive symptoms during pregnancy but not during the postpartum period. Low levels of depressive symptoms and lower than expected rates of clinical depression in both groups may partially be due to methodological issues. As perinatal depression is a significant public health problem, more work is needed to prevent perinatal depression in low-income, ethnically diverse women.

                Patients aged 60 and older who exceeded the threshold on the Centers for Epidemiologic Studies Depression Scale (CES-D) and the Hamilton Depression Rating Scale (HAM-D) and their primary care physicians.
                Physicians of intervention patients were provided with patient-specific treatment recommendations during 3 special visits scheduled specifically to address the patient's symptoms of depression. In general, physicians were encouraged to establish a diagnosis of depression and educate their patient about the diagnosis, discontinue medications that can cause or exacerbate depressive symptoms, initiate antidepressants when appropriate, and consider referral to psychiatry. Guidelines for prescribing antidepressants were provided. Control physicians received no intervention, and control patients received usual care.
                Frequency of recording a depression diagnosis, stopping medications associated with depression, initiating antidepressant medication, and psychiatry referral; mean changes in HAM-D and Sickness Impact Profile (SIP) scores.
                One hundred three physicians and 175 patients were involved in the clinical trial. Physicians of intervention patients were more likely to diagnose depression and prescribe antidepressants (P < 0.01). There were no differences between the groups in the frequency of stopping medications associated with depression or referrals to psychiatry. Medications with the strongest cause and effect relationship to depression were infrequently used in this cohort of patients. Although both groups showed improvement in HAM-D and SIP scores, we were unable to demonstrate significant differences in HAM-D or SIP scores between the 2 groups.
                Intensive screening and feedback of patient-specific treatment recommendations increased the recognition and treatment of late life depression by primary care physicians. However, we were unable to demonstrate significant improvement in depression or disability severity among intervention patients despite the informational support provided to their physicians. Efforts to improve the functional status of these patients may require more integrated interventions and more aggressive attempts to target psychosocial stressors traditionally outside the purview of primary care. The majority of randomised controlled trials examining the effectiveness of antenatal group interventions at preventing postnatal depression in "at risk" women have used a "psychoeducational" intervention. The aim of the present study is to evaluate the effectiveness of an antenatal cognitive behavioural group intervention in a primary care setting for pregnant women identified with mild to moderate symptoms in pregnancy and/or at risk of developing depression or anxiety in the perinatal period.
                Subjects were randomised to a CBT group intervention or control condition (information booklet) and administered the EPDS and STAI at pre (Time 1) and post intervention (Time 2), and at 2 months (Time 3) and 4 months postpartum (Time 4). MINIs were administered at Times 1, 3 and 4.
                Of the 774 women approached, 277 accepted and were suitable; thus 191 were randomised to the CBT intervention and 86 to the control condition. The subsequent 52% drop-out left 89 women "completing" the CBT groups and 43 in the control group; these two groups were well matched on demographic variables. Intention to treat analyses revealed relatively low mean baseline EPDS scores (means 6.88 -8.16) with no reduction in EPDS scores in either group from Time 1 to Time 4. MINI depression criteria were fulfilled by 19% of all participants at Time 1 but there was no reduction in depression in either group; in contrast those with MINI anxiety diagnoses reduced from 28% in late pregnancy to 16% at four months postpartum in the CBT group with similar reductions in the control group. Analyses on the 132 "completers" showed significant symptomatic improvement over time for both the CBT group and control condition. Depression scores in the most symptomatic women (EPDS>12; N=19) decreased steadily by over 50% over the total time course but there were no differences in improvement between the CBT and control groups.
                A number of methodological factors may have obscured our results including a tendency to natural remission in mildly symptomatic subjects and the possibility that our control condition was therapeutic in itself.
                While a modest reduction in depression scores was noted in study "completers", both the CBT group intervention control condition were equally beneficial. The reasons for this finding include the low symptom level at baseline; the potential effectiveness of the control condition; and the brevity of the intervention. This randomized, controlled trial tested the hypothesis that women identified as more vulnerable to developing postnatal depression who attended two specific antenatal groups and one postnatal group have a reduced frequency of postnatal depression from 37 to 15 percent at 6 weeks, 12 weeks, and 6 months postpartum. A modified antenatal screening questionnaire was completed, and women identified as more vulnerable to postnatal depression were stratified by parity and randomly allocated to receive extra support groups or to a control group. The Edinburgh Postnatal Depression Scale (EPDS) was used to detect postnatal depression. Attendance at the support groups was low, 31 percent overall. At six weeks, in the intervention group, 8 (13%) of 64 women scored high (> 12) on the EPDS, compared with 11 (17%) controls. Similarly, at 12 weeks 7 (11%) of 63 versus 10 (15%) of 65 women scored higher than 12, and at 6 months, 9 (15%) of 60 versus 6 (10%) of 64 women scored higher than 12, indicating that the intervention did not reduce postnatal depression. It is possible that the method of applying the intervention, using groups separate from the standard antenatal classes, may have affected attendance. More research is required into ways of reaching and supporting women who may become depressed.
It is not possible to make any recommendations for antidepressant treatment in postnatal depression from this single small trial. More trials are needed, with larger sample sizes and longer follow-up periods, to compare different antidepressants in the treatment of postnatal depression, to compare antidepressant treatment with psychosocial interventions and to assess adverse effects of antidepressants. Treatment of postnatal depression is an area that has been neglected despite the large public health impact described above.
