Depression in men in the postnatal period and later child psychopathology: a population cohort study

Objective: Postnatal depression in women is associated with adverse effects on both maternal health and children's development. It is unclear whether depression in men at this time poses comparable risks. The present study set out to assess the association between depression in men in the postnatal period and later psychiatric disorders in their children and to investigate predisposing factors for depression in men following childbirth. Method: A population-based cohort of 10,975 fathers and their children from the Avon Longitudinal Study of Parents and Children (ALSPAC) was recruited in the prenatal period and followed for 7 years. Paternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale and later child psychiatric disorder (DSM-IV) with the Development and Well-Being Assessment. Results: Depression in fathers in the postnatal period was significantly associated with psychiatric disorder in their children 7 years later (adjusted OR 1.72, 95% CI 1.07-2.77), most notably oppositional defiant/conduct disorders (adjusted OR 1.94, 95% CI 1.04-3.61), after adjusting for maternal depression and paternal educational level. A history of severe depression and high prenatal symptom scores for depression and anxiety were the strongest predictors of paternal depression in the postnatal period. Conclusions: Depression in fathers in the postnatal period is associated with later psychiatric disorders in their children, independently of maternal postnatal depression. Further research into the risks associated with paternal psychopathology is required because this could represent an important opportunity for public health intervention.

The effects of pre- and postnatal depression in fathers: a natural experiment comparing the effects of exposure to depression on offspring

Background: Depression in fathers in the postnatal period is associated with an increased risk of behavioural problems in their offspring, particularly for boys. The aim of this study was to examine for differential effects of depression in fathers on children's subsequent psychological functioning via a natural experiment comparing prenatal and postnatal exposure. Methods:In a longitudinal population cohort study (the Avon Longitudinal Study of Parents and Children (ALSPAC)) we examined the associations between depression in fathers measured in the prenatal and postnatal period (measured using the Edinburgh Postnatal Depression Scale), and later behavioural/emotional and psychiatric problems in their children, assessed at ages 31/2 and 7 years. Results: Children whose fathers were depressed in both the prenatal and postnatal periods had the highest risks of subsequent psychopathology, measured by total problems at age 31/2 years (Odds Ratio 3.55; 95% confidence interval 2.07, 6.08) and psychiatric diagnosis at age 7 years (OR 2.54; 1.19, 5.41). Few differences emerged when prenatal and postnatal depression exposure were directly compared, but when compared to fathers who were not depressed, boys whose fathers had postnatal depression only had higher rates of conduct problems aged 31/2 years (OR 2.14; 1.22, 3.72) whereas sons of the prenatal group did not (OR 1.41; .75, 2.65). These associations changed little when controlling for maternal depression and other potential confounding factors. Conclusions: The findings of this study suggest that the increased risk of later conduct problems, seen particularly in the sons of depressed fathers, maybe partly mediated through environmental means. In addition, children whose fathers are more chronically depressed appear to be at a higher risk of emotional and behavioural problems. Efforts to identify the precise mechanisms by which transmission of risk may occur should be encouraged to enable the development of focused interventions to mitigate risks for young children.

Controlled trial of the short- and long-term effect of psychological treatment of post-partum depression - 1. Impact on maternal mood!

Background: Psychological interventions for postnatal depression can be beneficial in the short term but their longer-term impact is unknown, Aims To evaluate the long-term effect on maternal mood of three psychological treatments in relation to routine primary care. Method: 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 18 and 60 months post-partum. Results: Compared with the control, ail 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 postpartum, treatment did not reduce subsequent episodes of post-partum depression. Conclusions: 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.

Trajectories of maternal depression and offspring psychopathology at 6 years: 2004 Pelotas cohort study

BACKGROUND: Few studies have addressed the course and severity of maternal depression and its effects on child psychiatric disorders from a longitudinal perspective. This study aimed to identify longitudinal patterns of maternal depression and to evaluate whether distinct depression trajectories predict particular psychiatric disorders in offspring. METHODS: Cohort of 4231 births followed-up in the city of Pelotas, Brazil. Maternal depressive symptoms were assessed with the Edinburgh Postnatal Depression Scale (EPDS) at 3, 12, 24 and 48 months and 6 years after delivery. Psychiatric disorders in 6-year-old children were evaluated through the development and well-being assessment (DAWBA) instrument. Trajectories of maternal depression were calculated using a group-based modelling approach. RESULTS: We identified five trajectories of maternal depressive symptoms: a "low" trajectory (34.8%), a "moderate low" (40.9%), a "increasing" (9.0%), a "decreasing" (9.9%), and a "high-chronic" trajectory (5.4%). The probability of children having any psychiatric disorder, as well as both internalizing and externalizing problems, increased as we moved from the "low" to the "high-chronic" trajectory. These differences were not explained by maternal and child characteristics examined in multivariate analyses. LIMITATIONS: Data on maternal depression at 3-months was available on only a sub-sample. In addition, we had to rely on maternal report of child's behavior alone. CONCLUSIONS: The study revealed an additive effect on child outcome of maternal depression over time. We identified a group of mothers with chronic and severe symptoms of depression throughout the first six years of the child life and for this group child psychiatric outcome was particularly compromised.

Internal consistency and validity of the Stroke Impact Scale 2.0 (SIS 2.0) and SIS - 16 in an Australian sample

Background and Purpose: The impact of stroke is multidimensional however standard stroke measures do not discriminate well when stroke patients are less physically impaired. The Stroke Impact Scale 2.0 (SIS 2.0) is a multidimensional measure of the impact of stroke but its'' psychometric properties require further testing. The SIS-16 is a measure of physical functioning designed to be more sensitive to differences in physical functioning than current stroke outcome measures but there is only preliminary information detailing its'' reliability and validity. The current study examined the internal consistency and validity of the SIS 2.0 and SIS-16 in an Australian sample of stroke patients. Methods: The SIS 2.0, SIS-16, World Health Organization Bref-Scale (WHOQOL-BREF) and Zung''s Self-Rating Depression Scale (SDS) were completed by 74 stroke patients in rural Victoria, Australia.
Results: The item convergent validity index indicated good item convergence of the SIS-16 and SIS 2.0 domains. The item discriminant validity index had only adequate divergence for most SIS 2.0 domains. Internal consistencies of the SIS-16 and SIS 2.0 domains were acceptable (agr = 0.87–0.95). Correlations between the SIS-16 and SIS 2.0 and the WHOQOL-BREF and SDS supported the convergent and discriminant validity of the SIS-16 and all the dimensions of the SIS 2.0 except lsquoParticipationrsquo which lacked discriminant validity. Conclusions: The SIS 2.0 and SIS-16 had good psychometric properties with support for the internal consistency and validity of both measures.

The clinical application of three screening tools for recognizing post-partum depression

Postnatal depression is a major health issue for childbearing women world-wide, as it is not always identified early. This study aimed to evaluate the clinical application of three screening instruments for the early recognition of post-partum depression, the Postpartum Depression Prediction Inventory, the Postpartum Depression Screening Scale and the Edinburgh Postnatal Depression Scale, and to examine nurse interventions following use of the instruments. Data were collected at two points, at 28 weeks prenatal (107 women) and eight weeks postnatal (84 women). Results showed that 17% of the women scored significant symptoms of post-partum depression and 10–15% had a positive screen for major postnatal depression. There was a statistically significant correlation between the total score on the Postpartum Depression Screening Scale and the Edinburgh Postnatal Depression Scale. Of those eight women identified as being at risk, seven had received anticipatory guidance and five had received counselling by the nurses. The Postpartum Depression Prediction Inventory enabled nurses to identify women at risk of post-partum depression and offer interventions.

The early detection of postpartum depression: midwives and nurses trial a checklist

Objective: To evaluate the use of a standard pen-and-paper test versus the use of a checklist for the early identification of women at risk of postpartum depression and to investigate the experiences of nurses in using the checklist.

Design: A prospective cohort design using repeated measures.

Setting: The booking-in prenatal clinic at a regional hospital in Victoria, Australia, and the community-based postpartum maternal and child health service.

Participants: 107 pregnant women over 20 years of age.

Main Measures: Postpartum Depression Prediction Inventory (PDPI), Postpartum Depression Screening Scale (PDSS), Edinburgh Postnatal Depression Scale (EPDS), demographic questionnaire, and data on the outcome from the midwives and nurses.

Results: The PDPI identified 45% of the women at risk of depression during pregnancy and 30% postpartum. The PDSS and EPDS both identified the same 8 women (10%), who scored highly for depression at the 8-week postpartum health visit. Nurses provided 80% of the women with anticipatory guidance on postpartum depression in the prenatal period and 46% of women at the 8-week postpartum health visit. Nurse counseling or anticipatory guidance was provided for 60% of the women in the prenatal period.

Conclusion: The PDPI was found to be a valuable checklist by many nurses involved in this research, particularly as a way of initiating open discussion with women about postpartum depression. It correlated strongly with both the PDSS and the EPDS, suggesting that it is useful as an inventory to identify women at risk of postpartum depression.

Prevalence of psychological distress, anxiety and depression in rural communities in Australia

Objective: To describe the prevalence of psychological distress, depression and anxiety in three Australian rural settings and to identify the levels of risk by gender and age.

Design and setting: Three cross-sectional surveys in the Greater Green Triangle area covering the south-east of South Australia (Limestone Coast), and south-west (Corangamite Shire) and north-west (Wimmera) of Victoria.

Participants: A total of 1563 people, aged 25–74 years, randomly selected from the electoral roll.

Main outcome measures: Psychological distress assessed by the Kessler 10, and anxiety and depression assessed by the Hospital Anxiety and Depression Scale.

Results: The prevalence of psychological distress was 31% for both men and women with two-thirds reporting moderate and one-third high levels of psychological distress. The prevalence of depression and anxiety was approximately 10%. The highest rate of psychological distress, anxiety and depression occurred in the 45–54 years age group. There were no consistent gender or area differences in the prevalence of psychological distress, depression or anxiety.

Conclusions: A third of the rural population reported psychological distress, with the highest prevalence observed in middle-aged men and women. Thus, health professionals should attend not only to physical health, but also to mental health status in this age group. It is also important to target prevention strategies at the 20% who reported moderate levels of psychological distress in order to prevent the development of more serious conditions.

Depression : an important comorbidity with metabolic syndrome in a general population

OBJECTIVE—There is a recognized association among depression, diabetes, and cardiovascular disease. The aim of this study was to examine in a sample representative of the general population whether depression, anxiety, and psychological distress are associated with metabolic syndrome and its components.

RESEARCH DESIGN AND METHODS—Three cross-sectional surveys including clinical health measures were completed in rural regions of Australia during 2004–2006. A stratified random sample (n = 1,690, response rate 48%) of men and women aged 25–84 years was selected from the electoral roll. Metabolic syndrome was defined by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults, Adult Treatment Panel III (NCEP ATP III), and International Diabetes Federation (IDF) criteria. Anxiety and depression were assessed by the Hospital Anxiety and Depression Scale and psychological distress by the Kessler 10 measure.

RESULTS—Metabolic syndrome was associated with depression but not psychological distress or anxiety. Participants with the metabolic syndrome had higher scores for depression (n = 409, mean score 3.41, 95% CI 3.12–3.70) than individuals without the metabolic syndrome (n = 936, mean 2.95, 95% CI 2.76–3.13). This association was also present in 338 participants with the metabolic syndrome and without diabetes (mean score 3.37, 95% CI 3.06–3.68). Large waist circumference and low HDL cholesterol showed significant and independent associations with depression.

CONCLUSIONS—Our results show an association between metabolic syndrome and depression in a heterogeneous sample. The presence of depression in individuals with the metabolic syndrome has implications for clinical management.

An examination of the 'gold standard' diagnosis of major depression in aged-care settings

Objectives: Individual clinical interviews are typically viewed as the “gold standard” when diagnosing major depressive disorder (MDD) and when examining the validity of self-rated questionnaires. However, this approach may be problematic with older people, who are known to underreport depressive symptomatology. This study examined the effect of including an informant interview on prevalence estimations of MDD in an aged-care sample.

Design: The results of an individual clinical interview for MDD were compared with those obtained when an informant interview was incorporated into the assessment. Results from each diagnostic approach were compared with scores on a self-rated depression instrument.

Setting: Low-level aged-care residential facilities in Melbourne (equivalent to “residential homes,” “homes for the elderly,” or “assisted living facilities” in other countries).

Participants: One hundred and sixty-eight aged-care residents (mean age: 84.68 years; SD: 6.16 years) with normal cognitive functioning.

Measurements: Individual clinical interviews were conducted using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders. This interview was modified for use with staff informants. Self-reported depression was measured using the Geriatric Depression Scale-15 (GDS-15).

Results: The estimated point prevalence of MDD rose from 16% to 22% by including an informant clinical interview in the diagnostic procedure. Overall, 27% of depressed residents failed to disclose symptoms in the clinical interview. The concordance of the GDS-15 with a diagnosis of MDD was substantially lower when an informant source was included in the diagnostic procedure.

Conclusion: Individual interviews and self-report questionnaires may be insufficient to detect depression among older adults. This study supports the use of an informant interview as an adjunct when diagnosing MDD among cognitively intact aged-care residents.

Raising the profile of depression in the workplace

The prevalence of depression in the Australian workforce is unknown. Epidemiological surveys (e.g., the National Health Survey and National Survey of Mental Health and Wellbeing) do not routinely include a depression scale and within the mental health field, few studies focus on depression and employment groups specifically. Although the inclusion of a direct measure of depression in  national surveys is preferable, the prevalence of depression may be inferred from short screening scales of general mental health. In this paper, scores on the  General Health Questionnaire (GHQ-12) and the Kessler psychological distress scale (K10) for a sample of employed persons were mapped onto the CES-D (Iowa) measure of depression. The results of this study indicate that the  recommended GHQ-12 cut-off point is appropriate for estimating work-related depression prevalence. However, the cut-off point on the K10 (the short-scale  currently used in Australian national surveys) may need to be substantially  reduced if scores on the K10 are to be used to identify workers at risk of  depression. The routine inclusion of a direct depression measure in national  surveys is recommended, particularly considering the number of employed persons in Australia and large proportion of the sample classified as depressed in this study.

Quality of life and depression among older patients waiting for joint replacement surgery

Purpose: Older patients waiting for joint replacement surgery in many western countries experience lengthy waits for their surgery. Although these patients suffer with mobility problems the nature of the disability associated with waiting for surgery is unclear. The purpose of this study was to determine health-related quality of life and symptoms of depression in persons waiting for their initial orthopaedic consultation following referral for total knee or total hip replacement surgery.

Methods: All patients who were waiting for an initial orthopaedic consultation for lower-limb joint replacement as at 25 August 2005 were surveyed. Participants were mailed questionnaires concerning demographic information, medical history, health-related quality of life (the Assessment of Quality of Life (AQoL) instrument), and symptoms of depression (Center for Epidemiologic Studies – Depression (CES-D) Scale).

Results: The 84 respondents (response rate 64%) had a mean age of 68.3 (SD 11.5 years), and 60% or respondents were women. Respondents reported an average of 1.6 (SD 0.9) medical conditions, and 85% reported osteoarthritis.} The average health-related quality of life was low (mean AQoL 0.38; SD 0.27), and near death-equivalent or worse than death-equivalent health-related quality of life (AQoL<0.1 of a maximum possible 1.0) was reported by 23% of the participants.The mean depression scale score was 16.5 (SD 11.1), and symptoms of depression (CES-D>16 of a maximum possible 60) were reported by 35% of the sample. There was a strong correlation between health-related quality of life and depression (r=–0.6).

Conclusions: Almost a third of patients waiting to see an orthopaedic surgeon about joint replacement surgery for their hip or knee had symptoms of depression. Geriatric rehabilitation services often provide interventions to these patients. The very poor quality of life reported suggests that more than exercise and strengthening will be needed to reduce disability.

Age-specific norms and determinants of anxiety and depression in 731 women with breast cancer recruited through a population-based cancer registry

The aim of this study was to determine population norms and determinants of anxiety and depression in a population-based sample of 731 women with breast cancer (aged 23–60 years) with the Hospital Anxiety and Depression scale (HADS). The prevalence of ‘probable’ psychological morbidity due to anxiety was 23% and due to depression was 3%. When the women identified as ‘possible’ cases were included, the respective proportions were 45 and 12%. Higher anxiety was present in younger, less educated women not born in Australia. There was no clear pattern of risk factors for depression. These population-based findings highlight the need for clinicians to be aware that age, education and country of birth may identify a particularly vulnerable subgroup. While brief scales such as the HADS are limited in their ability to accurately predict a clinical diagnosis, high scores identify those who may warrant referral for clinical evaluation.

Identification of depression in diabetes the efficacy of PHQ-9 and HADS-D

Background
Clinical guidelines advise screening for depression in patients with diabetes. The Patient Health Questionnaire (PHQ-9) and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D) are commonly used in primary care.

Aim
To compare the efficacy of HADS-D and PHQ-9 in identifying moderate to severe depression among primary care patients with type 2 diabetes.

Design of study
Self-report postal survey, clinical records assessed by GPs.

Setting
Seven metropolitan and rural general practices in Victoria, Australia.

Method
Postal questionnaires were sent to all patients with diabetes on the registers of seven practices in Victoria. A total of 561 completed postal questionnaires were returned, giving a response rate 47%. Surveys included demographic information, and history of diabetes and depression. Participants completed both the PHQ-9 and HADS-D. Clinical data from patient records included glycosylated hemoglobin (HbA1c) levels and medications.

Results
The proportion of the total sample completing HADS-D was 96.8% compared with 82.4% for PHQ-9. Level of education was unrelated to responses on the HADS-D but was related to completion of the PHQ-9. Using complete data (n = 456) from both measures, 40 responders showed HADS-D scores in the moderate to severe range, compared with 103 cases identified by PHQ-9. Only 35 cases were classified in the moderate to severe category by both the PHQ-9 and HADS-D. Items with the highest proportions of positive responses on the PHQ-9 were related to tiredness and sleeping problems and, on the HADS-D, feeling slowed down.

Conclusion
It may be that the items contributing to the higher prevalence of moderate to severe depression using the PHQ-9 are due to diabetes-related symptoms or sleep disorders.

A nurse-assisted screening and referral program for depression among survivors of colorectal cancer : feasibility study

Objective: To test the feasibility and acceptability of a telephone-based program to screen survivors of colorectal cancer (CRC) for distress, and to refer distressed patients to their treating health service.

Design, setting and participants: A prospective, multicentre study involving 59 patients with CRC recruited from six public and private health services in Melbourne, Victoria, from 15 June 2008 to 22 September 2009. Patients who had completed adjuvant chemotherapy for CRC were contacted (7–10 days after recruitment [outcall one] and again 4 weeks later [outcall two]) by the Cancer Council Victoria’s helpline nurse, and screened for distress with the Distress and Impact Thermometer (DIT); participants were given tailored information and support and those with distress scores of ≥5, and impact scores of ≥4, were referred for follow-up. Telephone interviews were conducted 4 weeks after outcall two. Participating helpline and health service staff were surveyed on the feasibility and acceptability of the service. Main outcome measure: Anxiety and depression, measured by the Hospital Anxiety and Depression Scale (HADS).

Results: Of the 59 patients (87%) who agreed to participate, 63% were men; their mean age was 59 years (SD, 9.5 years). HADS depression decreased significantly from baseline (mean score, 4.93; SD, 4.22) to follow-up (mean score, 3.84; SD, 4.10; Z = −2.375; P= 0.02). However, there was no significant difference in HADS anxiety between baseline (mean score, 5.29; SD, 4.11) and follow-up (mean score, 4.78; SD, 3.65). Outcall one generated two referrals (4% of participants) and outcall two generated four referrals
(8%); five of these six participants took up the referrals. Satisfaction with the program among participants was high; 82% found outcall one “quite or very helpful” and 79% found outcall two “quite or very helpful”. Helpline and health service staff reported a straightforward process that did not adversely affect workloads.

Conclusion: This model of care carries the potential to meet ongoing psychosocial needs of survivors of CRC.
