Detecting common mental disorders in primary care in India: a comparison of five screening questionnaires

Economic evaluation of a task-shifting intervention for common mental disorders in India

OBJECTIVE

To carry out an economic evaluation of a task-shifting intervention for the treatment of depressive and anxiety disorders in primary-care settings in Goa, India.

METHODS

Cost-utility and cost-effectiveness analyses based on generalized linear models were performed within a trial set in 24 public and private primary-care facilities. Subjects were randomly assigned to an intervention or a control arm. Eligible subjects in the intervention arm were given psycho-education, case management, interpersonal psychotherapy and/or antidepressants by lay health workers. Subjects in the control arm were treated by physicians. The use of health-care resources, the disability of each subject and degree of psychiatric morbidity, as measured by the Revised Clinical Interview Schedule, were determined at 2, 6 and 12 months.

FINDINGS

Complete data, from all three follow-ups, were collected from 1243 (75.4%) and 938 (81.7%) of the subjects enrolled in the study facilities from the public and private sectors, respectively. Within the public facilities, subjects in the intervention arm showed greater improvement in all the health outcomes investigated than those in the control arm. Time costs were also significantly lower in the intervention arm than in the control arm, whereas health system costs in the two arms were similar. Within the private facilities, however, the effectiveness and costs recorded in the two arms were similar.

CONCLUSION

Within public primary-care facilities in Goa, the use of lay health workers in the care of subjects with common mental disorders was not only cost-effective but also cost-saving.

The explanatory models of depression and anxiety in primary care: a qualitative study from India

BACKGROUND

The biggest barrier to treatment of common mental disorders in primary care settings is low recognition among health care providers. This study attempts to explore the explanatory models of common mental disorders (CMD) with the goal of identifying how they could help in improving the recognition, leading to effective treatment in primary care.

RESULTS

The paper describes findings of a cross sectional qualitative study nested within a large randomized controlled trial (the Manas trial). Semi structured interviews were conducted with 117 primary health care attendees (30 males and 87 females) suffering from CMD. Main findings of the study are that somatic phenomena were by far the most frequent presenting problems; however, psychological phenomena were relatively easily elicited on probing. Somatic phenomena were located within a biopsychosocial framework, and a substantial proportion of informants used the psychological construct of 'tension' or 'worry' to label their illness, but did not consider themselves as suffering from a 'mental disorder'. Very few gender differences were observed in the descriptions of symptoms but at the same time the pattern of adverse life events and social difficulties varied across gender.

CONCLUSION

Our study demonstrates how people present their illness through somatic complaints but clearly link their illness to their psychosocial world. However they do not associate their illness to a 'mental disorder' and this is an important phenomenon that needs to be recognized in management of CMD in primary settings. Our study also elicits important gender differences in the experience of CMD.

Reliability of the lay adherence counsellor administered substance abuse and mental illness symptoms screener (SAMISS) and the International HIV Dementia Scale (IHDS) in a primary care HIV clinic in Cape Town, South Africa

HIV infection is associated with an increased prevalence of common mental disorders and with the development of HIV associated neurological disorders (HAND). The aim of this research was to determine the reliability of lay adherence counsellors in the administration of the substance abuse and mental illness symptom screener (SAMISS) for common mental disorders and International HIV Dementia Scale (IHDS) for HAND in a South African sample of 269 people living with HIV/AIDS and on HAART in a primary healthcare setting. We used a cross-sectional design with each patient assessed by a mental health nurse and counsellor, 1 week apart. Reliability was fair for the SAMISS overall (κ = 0.39, CI(95) 0.29-0.49, P < 0.01), but was higher for the substance abuse component compared to the mental illness component. Reliability for the IHDS between counsellors and nurses was slight (κ = 0.11, CI(95) 0.00-0.27, P < 0.02). Counsellors tended not to miss symptoms, and detected symptoms more often than nurses for the both the SAMISS and IHDS. Strategies to improve the ability of primary healthcare providers to screen for neurocognitive disorders as well as avoiding over-detection of mental illness and substance abuse symptoms need to be developed and implemented for the primary healthcare setting.

Performance of the 6-item Kessler scale for measuring serious mental illness in Hong Kong

BACKGROUND

The 6-item Kessler scale (K6) promises to be a valuable epidemiological tool for assessing serious mental illness (SMI) in communities with limited resources for psychiatric research and treatment. Its performance in Chinese community has not been studied with reference to clinically assessed SMI.

METHOD

From a representative telephone-based population survey (n = 3014) that administered the K6, 153 participants were readministered the K6 and, on the same day, interviewed face-to-face by clinicians using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition, Axis I Disorder. Predictive indicators such as McNemar χ(2), area under receiver operating characteristic curve and stratum-specific likelihood ratios were used to investigate the concordance between the K6 and clinical status of SMI, individual-level predicted probabilities of having SMI, and the weighted prevalence of SMI in the community.

RESULT

The K6 exhibited high internal consistency and test-retest reliability. Factor analysis revealed 2 correlating components composed of depression and anxiety. Matching of K6 caseness and SMI status showed that at the cutoff of 12/13, the area under receiver operating characteristic curve was moderate (0.69). The K6 had high specificity and was a stronger screen-out than screen-in tool for SMI. The weighted prevalence estimate of SMI in Hong Kong was 6.5%. A person scoring 13 or above on the K6 has a probability of at least 22.2% of having SMI.

CONCLUSION

The Chinese K6 is reliable and generates the likelihood of SMI with substantial concordance with face-to-face clinical interviews in Hong Kong. It is a valuable tool for screening SMI, behavioral risk factor surveillance, and community epidemiological surveys.

Predictors of maternal psychological distress in rural India: a cross-sectional community-based study

BACKGROUND

Maternal common mental disorders are prevalent in low-resource settings and have far-reaching consequences for maternal and child health. We assessed the prevalence and predictors of psychological distress as a proxy for common mental disorders among mothers in rural Jharkhand and Orissa, eastern India, where over 40% of the population live below the poverty line and access to reproductive and mental health services is low.

METHOD

We screened 5801 mothers around 6 weeks after delivery using the Kessler-10 item scale, and identified predictors of distress using multiple hierarchical logistic regression.

RESULTS

11.5% (95% CI: 10.7-12.3) of mothers had symptoms of distress (K10 score >15). High maternal age, low asset ownership, health problems in the antepartum, delivery or postpartum periods, caesarean section, an unwanted pregnancy for the mother, small perceived infant size and a stillbirth or neonatal death were all independently associated with an increased risk of distress. The loss of an infant or an unwanted pregnancy increased the risk of distress considerably (AORs: 7.06 95% CI: 5.51-9.04 and 1.49, 95% CI: 1.12-1.97, respectively).

LIMITATIONS

We did not collect data on antepartum depression, domestic violence or a mother's past birth history, and were therefore unable to examine the importance of these factors as predictors of psychological distress.

CONCLUSIONS

Mothers living in underserved areas of India who experience infant loss, an unwanted pregnancy, health problems in the perinatal and postpartum periods and socio-economic disadvantage are at increased risk of distress and require access to reproductive healthcare with integrated mental health interventions.

Bullying behaviour in schools, socioeconomic position and psychiatric morbidity: a cross-sectional study in late adolescents in Greece

BACKGROUND

Bullying is quite prevalent in the school setting and has been associated with the socioeconomic position and psychiatric morbidity of the pupils. The aim of the study was to investigate the association between bullying and socioeconomic status in a sample of Greek adolescents and to examine whether this is confounded by the presence of psychiatric morbidity, including sub-threshold forms of illness.

METHODS

5,614 adolescents aged 16-18 years old and attending 25 senior high schools were screened and a stratified random sample of 2,427 were selected for a detailed interview. Psychiatric morbidity was assessed with a fully structured psychiatric interview, the revised Clinical Interview Schedule (CIS-R), while bullying was assessed with the revised Olweus bully/victim questionnaire. The following socio-economic variables were assessed: parental educational level and employment status, financial difficulties of the family and adolescents' school performance. The associations were investigated using multinomial logit models.

RESULTS

26.4% of the pupils were involved in bullying-related behaviours at least once monthly either as victims, perpetrators or both, while more frequent involvement (at least once weekly) was reported by 4.1%. Psychiatric morbidity was associated with all types of bullying-related behaviours. No socioeconomic associations were reported for victimization. A lower school performance and unemployment of the father were significantly more likely among perpetrators, while economic inactivity of the mother was more likely in pupils who were both victims and perpetrators. These results were largely confirmed when we focused on high frequency behaviours only. In addition, being overweight increased the risk of frequent victimization.

CONCLUSIONS

The prevalence of bullying among Greek pupils is substantial. Perpetration was associated with some dimensions of adolescents' socioeconomic status, while victimization showed no socioeconomic associations. Our findings may add to the understanding of possible risk factors for bullying behaviours in adolescence.

Common mental disorders in mothers vs. infant and obstetric outcomes: a review

INTRODUCTION

Pregnancy has been shown to increase women's vulnerability to mental disorders. Common mental disorders (CMDs) have been studied both in the general population and in pregnant vs. non-pregnant women. During pregnancy, CMDs have been considered a potential predictor of obstetric and infant outcomes.

METHODS

A search was conducted on the PubMed/MEDLINE, LILACS, and SciELO databases to find relevant articles written in English, Spanish, and Portuguese. No limit was established for year of publication, but only studies involving human beings were included.

RESULTS

A total of 25 articles were selected. There was a consensus among studies that the mean prevalence of CMD during pregnancy is 20%. There was also agreement that the occurrence of CMDs during pregnancy is a predictor of postpartum depression and anxiety disorders and that the disorder remains underdiagnosed and undertreated. As for the positive association between CMDs and obstetric and infant complications, results are still conflicting. In lower-income countries, frequently there is an association between CMD and perinatal changes. It is argued that some confounding factors, such as sociodemographic and cultural differences, health and maternal conditions, and type of instruments used, probably contribute to this lack of consensus.

CONCLUSION

We believe that the conflicting results found in the literature are caused by differences in methodology and sociodemographic factors that influence the development of CMDs. Despite these differences, our findings underscore the need for depression and anxiety disorders during pregnancy to be studied and better identified by all professionals who provide antenatal care.

Optimal cut-off score for diagnosing depression with the Patient Health Questionnaire (PHQ-9): a meta-analysis

BACKGROUND

The brief Patient Health Questionnaire (PHQ-9) is commonly used to screen for depression with 10 often recommended as the cut-off score. We summarized the psychometric properties of the PHQ-9 across a range of studies and cut-off scores to select the optimal cut-off for detecting depression.

METHODS

We searched Embase, MEDLINE and PsycINFO from 1999 to August 2010 for studies that reported the diagnostic accuracy of PHQ-9 to diagnose major depressive disorders. We calculated summary sensitivity, specificity, likelihood ratios and diagnostic odds ratios for detecting major depressive disorder at different cut-off scores and in different settings. We used random-effects bivariate meta-analysis at cutoff points between 7 and 15 to produce summary receiver operating characteristic curves.

RESULTS

We identified 18 validation studies (n = 7180) conducted in various clinical settings. Eleven studies provided details about the diagnostic properties of the questionnaire at more than one cut-off score (including 10), four studies reported a cut-off score of 10, and three studies reported cut-off scores other than 10. The pooled specificity results ranged from 0.73 (95% confidence interval [CI] 0.63-0.82) for a cut-off score of 7 to 0.96 (95% CI 0.94-0.97) for a cut-off score of 15. There was major variability in sensitivity for cut-off scores between 7 and 15. There were no substantial differences in the pooled sensitivity and specificity for a range of cut-off scores (8-11).

INTERPRETATION

The PHQ-9 was found to have acceptable diagnostic properties for detecting major depressive disorder for cut-off scores between 8 and 11. Authors of future validation studies should consistently report the outcomes for different cut-off scores.

Lay health worker led intervention for depressive and anxiety disorders in India: impact on clinical and disability outcomes over 12 months

BACKGROUND

Depressive and anxiety disorders (common mental disorders) are the most common psychiatric condition encountered in primary healthcare.

AIMS

To test the effectiveness of an intervention led by lay health counsellors in primary care settings (the MANAS intervention) to improve the outcomes of people with common mental disorders.

METHOD

Twenty-four primary care facilities (12 public, 12 private) in Goa (India) were randomised to provide either collaborative stepped care or enhanced usual care to adults who screened positive for common mental disorders. Participants were assessed at 2, 6 and 12 months for presence of ICD-10 common mental disorders, the severity of symptoms of depression and anxiety, suicidal behaviour and disability levels. All analyses were intention to treat and carried out separately for private and public facilities and adjusted for the design. The trial has been registered with clinical trials.gov (NCT00446407).

RESULTS

A total of 2796 participants were recruited. In public facilities, the intervention was consistently associated with strong beneficial effects over the 12 months on all outcomes. There was a 30% decrease in the prevalence of common mental disorders among those with baseline ICD-10 diagnoses (risk ratio (RR) = 0.70, 95% CI 0.53-0.92); and a similar effect among the subgroup of participants with depression (RR = 0.76, 95% CI 0.59-0.98). Suicide attempts/plans showed a 36% reduction over 12 months (RR=0.64, 95% CI0.42–0.98) among baseline ICD-10 cases. Strong effects were observed on days out of work and psychological morbidity, and modest effects on overall disability [corrected]. In contrast, there was little evidence of impact of the intervention on any outcome among participants attending private facilities.

CONCLUSIONS

Trained lay counsellors working within a collaborative-care model can reduce prevalence of common mental disorders, suicidal behaviour, psychological morbidity and disability days among those attending public primary care facilities.

The psychometric properties of the K10 and K6 scales in screening for mood and anxiety disorders in the South African Stress and Health study

Emerging research has provided support for the use of the Kessler Psychological Distress Scales in developing countries; however, this research has yet to be extended to southern Africa. This study sought to evaluate the performance of the Kessler scales in screening for depression and anxiety disorders in the South African population. The scales along with the Composite International Diagnostic Interview (CIDI) were included in the South African Stress and Health study, a nationally representative household survey. The K10/K6 demonstrated moderate discriminating ability in detecting depression and anxiety disorders in the general population; evidenced by area under the receiver operating curves of 0.73 and 0.72 respectively. However, both scales failed to meet our acceptability criteria of high sensitivity and high positive predictive value. Examinations of differences in responding by race/ethnicity revealed that the K10/K6 [Kessler Psychological Distress Scale 10-item (K10) and the abbreviated six-item (K6)] had significantly lower discriminating ability with respect to depression and anxiety disorders among the Black group (0.71) than among the combined minority race/ethnic groups of White, Colored, and Indian/Asian (0.78; p = 0.016). The difference in time period assessed on the K10/K6 (past 30  days) versus the CIDI (past 12  months) was a notable limitation of this study. Additional validation studies using clinician diagnostic instruments are recommended.

Association among physical, psychiatric and socioeconomic conditions and WHOQOL-Bref scores

The aim of this study is to investigate the impact of psychiatric morbidity, depression, cognitive deficit, number of self-reported illnesses and socio-demographic variables on the WHOQOL-Bref domain scores. WHOQOL-Bref domain scores are substantially affected by psychiatric morbidity and income. Depression, the number of self-reported illnesses and the female gender also explain the variability of other domains to a lesser extent.

Screening for perinatal common mental disorders in women in the north of Vietnam: a comparison of three psychometric instruments

BACKGROUND

There is increasing recognition that Perinatal Common Mental Disorders (CMDs) are a major public health problem for women in resource-constrained countries. There is an urgent need for screening tools suitable for use by community based health workers to assist in the identification of people with compromised mental health. The aim of this study was to establish the validity of three widely used psychometric screening instruments in detecting CMDs in women in northern Viet Nam.

METHODS

Translated and culturally verified versions of the Edinburgh Postnatal Depression Scale (EPDS), General Health Questionnaire 12 items (GHQ-12), Zung's Self-rated Anxiety Scale (Zung SAS) and a gold-standard diagnostic tool, the Structured Clinical Interview for DSM IV, were administered to a community-based representative cohort of 364 Vietnamese women in the perinatal period. Post-hoc analyses, Cronbach's alpha, and Receiver Operating Characteristic (ROC) analyses were performed to identify the optimal cut-off points and to compare the validity of three scales.

RESULTS

The Areas under the ROC Curve were: EPDS 0.77 (95%CI 0.72-0.82); Zung SAS 0.79 (95%CI 0.74-0.84) and GHQ-12 0.72 (95%CI 0.67-0.78). The optimal cut-off point for the EPDS was 3/4 (Se 69.7%; Sp 72.9%). The corresponding value for Zung SAS was 37/38 (Se 67.9%; Sp 75.3%) and for GHQ-12 was 0/1 (Se 77.1%; Sp 56.6%). The internal reliability Cronbach's alpha for EPDS was 0.75, for Zung SAS was 0.76, and for GHQ-12 was 0.64.

CONCLUSIONS

These instruments are suitable for use as screening tools for CMDs in women in northern Viet Nam, but probably because of differences in emotional literacy, familiarity with test-taking and the effects of chronic social adversity require much lower cut off scores to detect clinically significant symptoms than in other settings.

Do they actually work across borders? Evaluation of two measures of psychological distress as screening instruments in a non Anglo-Saxon country

Screening scales can be useful in searching for common mental disorders in primary care and in tracking relevant prevalence and correlates in community surveys. However, it is important to document their validity, before using them. We developed Italian versions of the widely-used K10 and K6 screening scales following the WHO forward-translation and back-translation protocol. To evaluate their effectiveness as screens for DSM-IV 12-month mood or anxiety disorders and "serious mental illness" (SMI), the scales were validated in a two-stage clinical reappraisal survey. In the first-phase, the scales were administered to 605 people. In the second-phase, a sub-sample of 147 first-phase respondents over-sampling screened positives was administered the 12-month version of the Structured Clinical Interview for DSM-IV Axis I Disorders as a clinical gold standard. Performance of the scales in screening for chosen disorders was assessed by calculating area under the receiver operating characteristic curve and stratum-specific likelihood ratios. Both the K10 and K6 performed well in detecting DSM-IV mood disorders, anxiety disorders, and serious mental illness (SMI), with areas under the curve (AUCs) (95% CIs) between 0.82 (0.75-0.89) and 0.91 (0.85-0.96). The Italian versions of the K6 and K10 scales have good psychometric properties, making them attractive inexpensive screens for mood disorders, anxiety disorders, and SMI.

Assessing prenatal depression in the rural developing world: a comparison of two screening measures

Significant levels of prenatal depression are reported from the Indian subcontinent (25–45%). A wide variety of measures have been used to screen for prenatal depression in western research. However, little evidence exists on the use of such measures in the context of the developing world. The objective of this study was to assess the validity of the Edinburgh Postnatal Depression Scale (EPDS) and the Kessler 10 Scale of Psychological Distress (K10) as screening measures for prenatal depression in rural South India. One hundred ninety-four women in their third trimester of pregnancy were assessed at a rural prenatal clinic in Karnataka, South India, using the EPDS, the K10 (scored 0–40) and a structured diagnostic psychiatric interview to establish a DSM-IV diagnosis of depression. Depressed women scored significantly higher on the EPDS and K-10 than controls. A receiver-operating characteristic analyses showed both scales to be good screening instruments for prenatal depression in rural South India at a cut-off of ≥13 on the EPDS (sensitivity = 100%, specificity = 84.90%, and area under the curve = 0.95) and ≥6 on the K10 (sensitivity = 100%, specificity = 81.30%, and area under the curve = 0.95). The EPDS and K10 have thus been shown to have equally good sensitivity and specificity in rural settings in the developing world at a cut-off score of ≥13 and ≥6, respectively. This study demonstrates the validity of the EPDS and K10 in screening pregnant women for depression during their prenatal check-ups.

International comparison of clinicians' ability to identify depression in primary care: meta-analysis and meta-regression of predictors

BACKGROUND

There are international differences in the epidemiology of depression and the performance of primary care physicians but the factors underlying these national differences are uncertain.

AIM

To examine the international variability in diagnostic performance of primary care physicians when diagnosing depression in primary care.

DESIGN OF STUDY

A meta-analysis of unassisted clinical diagnoses against semi-structured interviews.

METHOD

A systematic literature search, critical appraisal, and pooled analysis were conducted and 25 international studies were identified involving 8917 individuals. A minimum of three independent studies per country were required to aid extrapolation.

RESULTS

Clinicians in the Netherlands performed best at case finding (the ability to rule in cases of depression with minimal false positives) (AUC+ 0.735) and this was statistically significantly better than the ability of clinicians in Australia (AUC+ 0.622) and the US (AUC+ 0.653), who were the worst performers. Clinicians from Italy had intermediate case-finding abilities. Regarding screening (the ability to rule out cases of no depression with minimal false negatives) there were no strong differences. Looking at overall accuracy, primary care physicians in Italy and the Netherlands were most successful in their diagnoses and physicians from the US and Australia least successful (83.5%, 81.9%, 74.3%, and 67.0%, respectively). GPs in the UK appeared to have the lowest ability to detect depression, as a proportion of all cases of depression (45.6%; 95% CI = 27.7% to 64.2%). Several factors influenced detection accuracy including: collecting data on clinical outcomes; routinely comparing the clinical performance of staff; working in small practices; and having long waits to see a specialist.

CONCLUSION

Assuming these differences are representative, there appear to be international variations in the ability of primary care physicians to diagnose depression, but little differences in screening success. These might be explained by organisational factors.

Validation of brief screening tools for depressive and alcohol use disorders among TB and HIV patients in primary care in Zambia

BACKGROUND

This study was conducted to evaluate the diagnostic accuracy and determine the optimum cut-off scores for clinical use of the Center for Epidemiological Studies Depression scale (CES-D) and Alcohol Use Disorders Identification Test (AUDIT) against a reference psychiatric diagnostic interview, in TB and anti-retroviral therapy (ART) patients in primary care in Zambia.

METHODS

This was a cross-sectional study in 16 primary level care clinics. Consecutive sampling was used to select 649 participants who started TB treatment or ART in the preceding month. Participants were first interviewed using the CES-D and AUDIT, and subsequently with a psychiatric diagnostic interview for current major depressive disorder (MDD) and alcohol use disorders (AUDs) using the Mini-International Neuropsychiatric Interview (MINI). The diagnostic accuracy was calculated using the Area Under the Receiver Operating Characteristic curve (AUROC). The optimum cut-off scores for clinical use were calculated using sensitivity and positive predictive value (PPV).

RESULTS

The CES-D and AUDIT had high internal consistency (Cronbach's alpha = 0.84; 0.98 respectively). Confirmatory factor analysis showed that the four-factor CES-D model was not a good fit for the data (Tucker-Lewis Fit Index (TLI) = 0.86; standardized root-mean square residual (SRMR) = 0.06) while the two-factor AUDIT model fitted the data well (TFI = 0.99; SRMR = 0.04). Both the CES-D and AUDIT demonstrated good discriminatory ability in detecting MINI-defined current MDDs and AUDs (AUROC for CES-D = 0.78; AUDIT = 0.98 for women and 0.75 for men). The optimum CES-D cut-off score in screening for current MDD was 22 (sensitivity 73%, PPV 76%) while that of the AUDIT in screening for AUD was 24 for women (sensitivity 60%, PPV 60%), and 20 for men (sensitivity 55%, PPV 50%).

CONCLUSIONS

The CES-D and AUDIT showed high discriminatory ability in measuring MINI-defined current MDD and AUD respectively. They are suitable mental health screening tools for use among TB and ART patients in primary care in Zambia.

Kessler Psychological Distress Scale: normative data from the 2007 Australian National Survey of Mental Health and Wellbeing

OBJECTIVE

To present Australian normative data on the ten-item Kessler Psychological Distress Scale (K10).

METHOD

Analysis of cross-sectional data from the 2007 Australian National Survey of Mental Health and Wellbeing, a nationally representative household survey of 8841 adults. Mean K10 scores and K10 scores at selected percentiles of the K10 score distribution are presented by sex, age, the presence of mental disorders and the presence of physical conditions. Stratum-specific likelihood ratios were computed to help clinicians and researchers calculate predicted probabilities of mental disorder given scores on the K10.

RESULTS

Scores on the K10 were generally higher in women compared to men, in people with a mental disorder compared to without a mental disorder and in people with affective disorders compared to people with substance use disorders. The SSLRs were informative in ruling in a diagnosis of mental disorder, particularly at the high or very high end of the psychological distress spectrum.

CONCLUSIONS

These data may be helpful for clinicians and researchers alike in understanding the likelihood of mental disorder in a given individual or sample.

Validation of the structural coherency of the General Health Questionnaire

OBJECTIVE: Investigate the structural coherency of the 60-item version of the General Health Questionnaire via exploratory and confirmatory factor analyses. METHOD: The study design is a cross-sectional survey. A random sample of 146 individuals from the city of Divinópolis-MG volunteered to participate in the present study and responded to the 60-item version of the General Health Questionnaire adapted and validated for use in Brazil. Statistics consisted of exploratory and confirmatory factor analysis. Reliability was estimated using Cronbach's alpha method. RESULTS: Alpha coefficients for all five content scales of the General Health Questionnaire were high (α > 0.8). For four of the five scales, a unifactorial model of constituent items provided a good fit to the data. Items comprising the fifth scale, Psychic Stress, exhibited a two-correlated factor structure. A factor analysis of scores for the five scales yielded strong evidence of coherency, with all scales loading substantially on a single common factor. CONCLUSION: The General Health Questionnaire shows good psychometric coherency as evidenced by high internal consistency and unidimensionality of all but one of its constituent scales, and uniformly high loadings of all scales on a single overarching factor. These results are consistent with prior findings from the General Health Questionnaire developmental study and Brazilian adaptation studies.

Transtornos mentais comuns e qualidade de vida em jovens: uma amostra populacional de Pelotas, Rio Grande do Sul, Brasil

O objetivo foi verificar a prevalência de transtornos mentais comuns (TMC) e sua associação com qualidade de vida em jovens da cidade de Pelotas, Rio Grande do Sul, Brasil. Estudo transversal de base populacional com jovens de 18 a 24 anos. A seleção amostral foi realizada por conglomerados. Para a investigação dos transtornos mentais comuns foi aplicado o Self Report Questionnaire (SRQ-20), enquanto os níveis de qualidade de vida foram mensurados por intermédio da Medical Outcomes Survey Short-form General Health Survey (SF-36). A prevalência de TMC na amostra estudada foi de 24,5% (N = 382), apresentando-se mais evidente entre as mulheres, entre aqueles que pertenciam à menor classe socioeconômica (D ou E), não estavam estudando, não estavam trabalhando, consumiram álcool e usaram tabaco pelo menos uma vez na última semana e que fizeram uso de alguma substância ilícita nos últimos três meses. Os jovens com TMC obtiveram uma menor média nos escores da SF-36 em todos os domínios de qualidade de vida avaliados. Deve-se investir em medidas preventivas de TMC no intuito de proporcionar uma melhor qualidade de vida à população.

Effectiveness of an intervention led by lay health counsellors for depressive and anxiety disorders in primary care in Goa, India (MANAS): a cluster randomised controlled trial

BACKGROUND

Depression and anxiety disorders are common mental disorders worldwide. The MANAS trial aimed to test the effectiveness of an intervention led by lay health counsellors in primary care settings to improve outcomes of people with these disorders.

METHODS

In this cluster randomised trial, primary care facilities in Goa, India, were assigned (1:1) by computer-generated randomised sequence to intervention or control (enhanced usual care) groups. All adults who screened positive for common mental disorders were eligible. The collaborative stepped-care intervention offered case management and psychosocial interventions, provided by a trained lay health counsellor, supplemented by antidepressant drugs by the primary care physician and supervision by a mental health specialist. The research assessor was masked. The primary outcome was recovery from common mental disorders as defined by the International Statistical Classification of Diseases and Related Health Problems-10th revision (ICD-10) at 6 months. This study is registered with ClinicalTrials.gov, number NCT00446407.

FINDINGS

24 study clusters, with an equal proportion of public and private facilities, were randomised equally between groups. 1160 of 1360 (85%) patients in the intervention group and 1269 of 1436 (88%) in the control group completed the outcome assessment. Patients with ICD-10-confirmed common mental disorders in the intervention group were more likely to have recovered at 6 months than were those in the control group (n=620 [65·0%] vs 553 [52·9%]; risk ratio 1·22, 95% CI 1·00-1·47; risk difference=12·1%, 95% CI 1·6%-22·5%). The intervention had strong evidence of an effect in public facility attenders (369 [65·9%] vs 267 [42·5%], risk ratio 1·55, 95% CI 1·02-2·35) but no evidence for an effect in private facility attenders (251 [64·1%] vs 286 [65·9%], risk ratio 0·95, 0·74-1·22). There were three deaths and four suicide attempts in the collaborative stepped-care group and six deaths and six suicide attempts in the enhanced usual care group. None of the deaths were from suicide.

INTERPRETATION

A trained lay counsellor-led collaborative care intervention can lead to an improvement in recovery from CMD among patients attending public primary care facilities.

Association of socio-economic, gender and health factors with common mental disorders in women: a population-based study of 5703 married rural women in India

BACKGROUND

There are few population-based studies from low- and middle-income countries that have described the association of socio-economic, gender and health factors with common mental disorders (CMDs) in rural women.

METHODS

Population-based study of currently married rural women in the age group of 15-39 years. The baseline data are from the National Family Health Survey-II conducted in 1998. A follow-up study was conducted 4 years later in 2002-03. The outcome of CMD was assessed using the 12-item General Health Questionnaire (GHQ-12). Due to the hierarchical nature and complex survey design, data were analysed using mixed-effect logistic regression with random intercept model.

RESULTS

A total of 5703 women (representing 83.5% of eligible women) completed follow-up. The outcome of CMD was observed in 609 women (10.7%, 95% confidence interval 9.8-11.6). The following factors were independently associated with the outcome of CMD in the final multivariable model: higher age, low education, low standard of living, recent intimate partner violence (IPV), husband's unsatisfactory reaction to dowry, husband's alcohol use and women's own tobacco use.

CONCLUSIONS

Socio-economic and gender disadvantage factors are independently associated with CMDs in this population of women. Strategies that address structural determinants, for example to promote women's education and reduce their exposure to IPV, may reduce the burden of CMDs in women.

Detection of common mental disorder and alcohol use disorders in HIV infected people: A validation study in Goa, India

This study aims to validate a brief screening instrument to detect common mental disorder and alcohol use disorders in HIV infected people (PLHIV). The instrument consisting of Kessler's psychological distress scale-6 (K-6) and the Rapid Alcohol Problems Screen (RAPS) was administered to 109 PLHIV and compared to a reference standard psychiatrist's diagnosis. A cut-off score of 13 on the K-6 (sensitivity 68.4%, positive predictive value 58.7%, area under the ROC curve 0.78) and 1 on the RAPS (sensitivity 70.0%, positive predictive value 58.3%, area under ROC curve 0.82) were chosen as suitable. The instrument can be used by lay community workers.

Angina in primary care in Goa, India: sex differences and associated risk factors

BACKGROUND

Little is known about the prevalence of angina in people seen in Indian general practices. The authors assessed the prevalence of angina and its associated risk factors in Goan general practices.

METHODS

Cross-sectional study on consecutive attendees in nine private general practices in Goa, India. All participants completed the Rose Angina Questionnaire, to ascertain the presence of angina. Other demographic, clinical and biochemical data were also collected.

RESULTS

1556 (626 men and 930 women) consecutive attendees aged 30 to 75 years. Angina was detected in 37 (5.9%, 95% CI 2.4 to 9.4%) men and 99 (10.6%, 95% CI=7.4 to 11.2%) women. The prevalence of angina increased with age in both sexes but was greater in women between aged 46-60 (OR=4.3 (95% CI 2.0 to 9.2)) when compared with men. When compared with men, the odds of angina in women of all ages was 2.03 (95% CI 1.10 to 3.75) after controlling for confounders. Angina was associated with depressive and/or anxiety symptoms in both sexes (men OR=5.65, 95% CI=2.25 to 14.16; women OR=2.18, 95% CI=1.01 to 4.69) and with hypertension in men (OR=3.82, 95% CI=1.57 to 9.30) and family history of coronary heart disease (OR=1.53, 95% CI 1.05 to 2.24) in women. Borderline/high total cholesterol levels (OR=0.5, 95% CI 0.28 to 0.89) in women were associated with a reduced risk of angina.

CONCLUSION

Women attending general practices in Goa, India are at greater risk of angina than men. Depression/anxiety is strongly associated with angina. Greater awareness of the general practitioners to the disparity in angina between the sexes and its association with psychological distress is required.

The Patient Health Questionnaire Somatic, Anxiety, and Depressive Symptom Scales: a systematic review

BACKGROUND

Depression, anxiety and somatization are the most common mental disorders in primary care as well as medical specialty populations; each is present in at least 5-10% of patients and frequently comorbid with one another. An efficient means for measuring and monitoring all three conditions would be desirable.

METHODS

Evidence regarding the psychometric and pragmatic characteristics of the Patient Health Questionnaire (PHQ)-9 depression, generalized anxiety disorder (GAD)-7 anxiety and PHQ-15 somatic symptom scales are synthesized from two sources: (1) four multisite cross-sectional studies (three conducted in primary care and one in obstetric-gynecology practices) comprising 9740 patients, and (2) key studies from the literature that have studied these scales.

RESULTS

The PHQ-9 and its abbreviated eight-item (PHQ-8) and two-item (PHQ-2) versions have good sensitivity and specificity for detecting depressive disorders. Likewise, the GAD-7 and its abbreviated two-item (GAD-2) version have good operating characteristics for detecting generalized anxiety, panic, social anxiety and post-traumatic stress disorder. The optimal cutpoint is > or = 10 on the parent scales (PHQ-9 and GAD-7) and > or = 3 on the ultra-brief versions (PHQ-2 and GAD-2). The PHQ-15 is equal or superior to other brief measures for assessing somatic symptoms and screening for somatoform disorders. Cutpoints of 5, 10 and 15 represent mild, moderate and severe symptom levels on all three scales. Sensitivity to change is well-established for the PHQ-9 and emerging albeit not yet definitive for the GAD-7 and PHQ-15.

CONCLUSIONS

The PHQ-9, GAD-7 and PHQ-15 are brief well-validated measures for detecting and monitoring depression, anxiety and somatization.

Screening for serious mental illness in the general population with the K6 screening scale: results from the WHO World Mental Health (WMH) survey initiative

Data are reported on the background and performance of the K6 screening scale for serious mental illness (SMI) in the World Health Organization (WHO) World Mental Health (WMH) surveys. The K6 is a six-item scale developed to provide a brief valid screen for Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) SMI based on the criteria in the US ADAMHA Reorganization Act. Although methodological studies have documented good K6 validity in a number of countries, optimal scoring rules have never been proposed. Such rules are presented here based on analysis of K6 data in nationally or regionally representative WMH surveys in 14 countries (combined N = 41,770 respondents). Twelve-month prevalence of DSM-IV SMI was assessed with the fully-structured WHO Composite International Diagnostic Interview. Nested logistic regression analysis was used to generate estimates of the predicted probability of SMI for each respondent from K6 scores, taking into consideration the possibility of variable concordance as a function of respondent age, gender, education, and country. Concordance, assessed by calculating the area under the receiver operating characteristic curve, was generally substantial (median 0.83; range 0.76-0.89; inter-quartile range 0.81-0.85). Based on this result, optimal scaling rules are presented for use by investigators working with the K6 scale in the countries studied.

Assessment of mood: guides for clinicians

OBJECTIVE

This article is one of the series of review articles aiming to present a convenient guideline for practicing clinicians in their selection of scales for clinical and research purposes. This article focuses on assessment scales for mood (depression, mania).

METHODS

After reviewing the basic principles of clinical psychometrics, we present a selective review of representative scales measuring depressed or manic mood.

RESULTS

We reviewed and reported on reliability, validity, interpretability, and feasibility of the following rating scales: Patient Health Questionnaire-9 (PHQ-9), K6, Beck Depression Inventory II (BDI-II), and Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) as self-report scales for depressed mood; Hamilton Rating Scale for Depression (HAM-D) and Montgomery-Asberg Depression Rating Scale (MADRS) as clinician-administered measure for depression; and Young Mania Rating Scale (YMRS) as a clinician-administered instrument for mania.

CONCLUSION

Although the rating scales for mood represent a well-trodden terrain, this brief review of the most frequently used scales in the literature revealed there is still some room for improvement and for further research, especially with regard to their clinical interpretability.

Common mental disorder and associated factors amongst women with young infants in rural Malawi

BACKGROUND

Common mental disorder (CMD) affecting women during the childbearing years is an important health problem in low and middle income countries. This study investigates CMD and associated factors amongst women with young infants in rural Malawi.

METHODS

In this cross-sectional study, mothers of infants due for measles vaccination were recruited from a district hospital child health clinic. Maternal CMD was measured using a Chichewa version of the Self-Reporting Questionnaire (SRQ). DSM-IV diagnoses of major and minor depressive disorder were made using the structured clinical interview for DSM-IV (SCID). Socio-demographic, maternal and infant variables were measured and associations with CMD were determined.

RESULTS

Of 519 eligible women, 501 were included in the analysis. Mean age was 24.4 years and median infant age was 9.9 months. The weighted prevalence of any current depressive episode (minor or major) was 30.4% (95% CI 22.8-38.1%). The weighted prevalence of current major depressive episode was 13.9% (95% CI 8.2-19.5%). Mean SRQ score for the total sample was 5.71 (SD 4.42). On multivariate analysis, SRQ score was significantly associated with lower socioeconomic status, lack of a confiding relationship with partner or relative, and recent infant illness. Amongst the women who knew their HIV status (n = 314), SRQ score was also associated with HIV infection.

CONCLUSIONS

This study demonstrates that CMD is a significant health burden among women with infants in rural Malawi, and is associated with poverty, relationship difficulties, HIV infection and infant health problems.

Effect of a participatory intervention with women's groups on birth outcomes and maternal depression in Jharkhand and Orissa, India: a cluster-randomised controlled trial

BACKGROUND

Community mobilisation through participatory women's groups might improve birth outcomes in poor rural communities. We therefore assessed this approach in a largely tribal and rural population in three districts in eastern India.

METHODS

From 36 clusters in Jharkhand and Orissa, with an estimated population of 228 186, we assigned 18 clusters to intervention or control using stratified randomisation. Women were eligible to participate if they were aged 15-49 years, residing in the project area, and had given birth during the study. In intervention clusters, a facilitator convened 13 groups every month to support participatory action and learning for women, and facilitated the development and implementation of strategies to address maternal and newborn health problems. The primary outcomes were reductions in neonatal mortality rate (NMR) and maternal depression scores. Analysis was by intention to treat. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN21817853.

FINDINGS

After baseline surveillance of 4692 births, we monitored outcomes for 19 030 births during 3 years (2005-08). NMRs per 1000 were 55.6, 37.1, and 36.3 during the first, second, and third years, respectively, in intervention clusters, and 53.4, 59.6, and 64.3, respectively, in control clusters. NMR was 32% lower in intervention clusters adjusted for clustering, stratification, and baseline differences (odds ratio 0.68, 95% CI 0.59-0.78) during the 3 years, and 45% lower in years 2 and 3 (0.55, 0.46-0.66). Although we did not note a significant effect on maternal depression overall, reduction in moderate depression was 57% in year 3 (0.43, 0.23-0.80).

INTERPRETATION

This intervention could be used with or as a potential alternative to health-worker-led interventions, and presents new opportunities for policy makers to improve maternal and newborn health outcomes in poor populations.

Partner alcohol use, violence and women's mental health: population-based survey in India

BACKGROUND

The relationship between partner alcohol use and violence as risk factors for poor mental health in women is unclear.

AIMS

To describe partner-related and other psychosocial risk factors for common mental disorders in women and examine interrelationships between these factors.

METHOD

Data are reported on 821 women aged 18-49 years from a larger population study in north Goa, India. Logistic regression models evaluated the risks for women's common mental disorders and tested for mediation effects in the relationship between partner alcohol use and these disorders.

RESULTS

Excessive partner alcohol use increased the risk for common mental disorders two- to threefold. Partner violence and alcohol-related problems each partially mediated the association between partner excessive alcohol use and these mental disorders. Women's own violence-related attitudes were also independently associated with them.

CONCLUSIONS

Partner alcohol use, partner violence and women's violence-related attitudes must be addressed to prevent and treat common mental disorders in women.

The Everyday Feeling Questionnaire: the structure and validation of a measure of general psychological well-being and distress

BACKGROUND

Psychological distress and well-being underlie the continuum of susceptibility to common mental disorders. Our objective was to provide a simple and acceptable measure of psychological distress and well-being to collect information from subjects and informants in non-clinical samples, to explore its internal structure, concurrent and external validity.

METHOD

Self and partner versions of the ten-item Everyday Feeling Questionnaire (EFQ) were administered to 5,279 adults. The 12-item General Health Questionnaire (GHQ) was used to establish concurrent validity. Socioeconomic status, child psychopathology, and family functioning served as external validators.

RESULTS

The EFQ was internally consistent with all items loading strongly on a single common factor. Item response analysis showed excellent sensitivity of the ten items, balanced contribution of well-being and distress items and good information content across a broad range. The internal structure of partner version did not differ from self-report. The constructs measured by the EFQ and GHQ were distinct, but highly correlated. The EFQ's correlations with external validators were stronger than GHQ's ones.

CONCLUSION

Psychological well-being and distress are measurable as a single construct, using the EFQ. The partner-report version will facilitate the collection of data on multiple household members or on the same individual from two or more sources.

Packages of care for depression in low- and middle-income countries

In the first in a series of six articles on packages of care for mental disorders in low- and middle-income countries, Neerja Chowdary and colleagues discuss the treatment of depression.

Common mental disorders during pregnancy: prevalence and associated factors among low-income women in São Paulo, Brazil: depression and anxiety during pregnancy

To estimate the prevalence of common mental disorders (CMD) and factors associated with these disorders among pregnant women of low socio-economic status (SES) in São Paulo. We performed a cross-sectional study with 831 women in their 20th to 30th weeks of pregnancy, who were attending antenatal clinics in primary care in São Paulo, Brazil. CMD were assessed with the Clinical Interview Schedule-Revised. Crude and adjusted prevalence ratios and 95%CI were calculated to examine the association between CMD and exposure variables. The prevalence of CMD was 20.2% (95%CI 17.5 to 23.0). Age at current pregnancy and at first delivery, current obstetric complications, not having friends in the community, living in a crowded household, lower occupational status and history of previous psychiatric treatment were all independently associated with increased prevalence of CMD. CMD is highly prevalent among pregnant women of low SES seen in primary care settings in São Paulo. A combination of distal and proximal psychosocial factors increase the risk for CMD. Primary health care professionals need to be aware of how common CMD in such settings and properly trained to deal with CMD during pregnancy.

Detecting alcohol-related problems in developing countries: a comparison of 2 screening measures in India

BACKGROUND

There is inadequate recognition of alcohol misuse as a public health issue in India. Information on screening measures is critical for prevention and early intervention efforts. This study critically evaluated the full and shorter versions of the AUDIT and RAPS4-QF as screening measures for alcohol use disorders (AUDs) in a community sample of male drinkers in Goa, India.

METHODS

Data from male drinking respondents in a population study on alcohol use patterns and sexual risk behaviors in randomly selected rural and urban areas of North Goa are reported. Overall, 39% (n = 743) of the 1899 screened men, age 18 to 49, reported consuming alcohol in the last 12 months. These current drinkers were administered the screening measures as part of detailed interviews on drinking patterns and AUD symptoms. Receiver Operating Characteristic (ROC) analysis was conducted for each combination of screening measure and criterion (alcohol dependence or any AUD). Reliability and correlations among the 4 measures were also examined.

RESULTS

All 4 measures performed well with area under the curves of at least 0.79. The full screeners that included both drinking patterns and problem items (the AUDIT and the RAP4-QF) performed better than their shorter versions (the AUDIT-C and the RAPS4) in detecting AUDs. Performance of the AUDIT and RAPS4-QF improved with lowered and raised thresholds, respectively, and alternate cut-off scores are suggested. Scores on the full measures were significantly correlated (0.80). Reliability estimates for the AUDIT measures were higher than those for the RAPS4 measures.

CONCLUSIONS

All measures were efficient at detecting AUDs. When screening for alcohol-related problems among males in the general population in India, cut-off scores for screeners may need to be adjusted. Selecting an appropriate screening measure and cut-off score necessitates careful consideration of the screening context and resources available to confirm alcohol-related diagnoses.

Suicidal behavior among female sex workers in Goa, India: the silent epidemic

OBJECTIVES

We sought to study suicidal behavior prevalence and its association with social and gender disadvantage, sex work, and health factors among female sex workers in Goa, India.

METHODS

Using respondent-driven sampling, we recruited 326 sex workers in Goa for an interviewer-administered questionnaire regarding self-harming behaviors, sociodemographics, sex work, gender disadvantage, and health. Participants were tested for sexually transmitted infections. We used multivariate analysis to define suicide attempt determinants.

RESULTS

Nineteen percent of sex workers in the sample reported attempted suicide in the past 3 months. Attempts were independently associated with intimate partner violence (adjusted odds ratio [AOR] = 2.70; 95% confidence interval [CI] = 1.38, 5.28), violence from others (AOR = 2.26; 95% CI = 1.15, 4.45), entrapment (AOR = 2.76; 95% CI = 1.11, 6.83), regular customers (AOR = 3.20; 95% CI = 1.61, 6.35), and worsening mental health (AOR = 1.05; 95% CI = 1.01, 1.11). Lower suicide attempt likelihood was associated with Kannad ethnicity, HIV prevention services, and having a child.

CONCLUSIONS

Suicidal behaviors among sex workers were common and associated with gender disadvantage and poor mental health. India's widespread HIV-prevention programs for sex workers provide an opportunity for community-based interventions against gender-based violence and for mental health services delivery.

Associations of C-reactive protein and interleukin-6 with cognitive symptoms of depression: 12-year follow-up of the Whitehall II study

BACKGROUND

A lack of longitudinal studies has made it difficult to establish the direction of associations between circulating concentrations of low-grade chronic inflammatory markers, such as C-reactive protein and interleukin-6, and cognitive symptoms of depression. The present study sought to assess whether C-reactive protein and interleukin-6 predict cognitive symptoms of depression or whether these symptoms predict inflammatory markers.

METHOD

In a prospective occupational cohort study of British white-collar civil servants (the Whitehall II study), serum C-reactive protein, interleukin-6 and cognitive symptoms of depression were measured at baseline in 1991-1993 and at follow-up in 2002-2004, an average follow-up of 11.8 years. Symptoms of depression were measured with four items describing cognitive symptoms of depression from the General Health Questionnaire. The number of participants varied between 3339 and 3070 (mean age 50 years, 30% women) depending on the analysis.

RESULTS

Baseline C-reactive protein (beta=0.046, p=0.004) and interleukin-6 (beta=0.046, p=0.005) predicted cognitive symptoms of depression at follow-up, while baseline symptoms of depression did not predict inflammatory markers at follow-up. After full adjustment for sociodemographic, behavioural and biological risk factors, health conditions, medication use and baseline cognitive systems of depression, baseline C-reactive protein (beta=0.038, p=0.036) and interleukin-6 (beta=0.041, p=0.018) remained predictive of cognitive symptoms of depression at follow-up.

CONCLUSIONS

These findings suggest that inflammation precedes depression at least with regard to the cognitive symptoms of depression.

Validation of a Chichewa version of the self-reporting questionnaire (SRQ) as a brief screening measure for maternal depressive disorder in Malawi, Africa

BACKGROUND

Depressive disorder affecting women during the perinatal period is common in low-income countries. The detection and study of maternal depression in a resource-poor setting requires a brief screening tool that is both accurate and practical to administer.

METHOD

A Chichewa version of the Self Reporting Questionnaire (SRQ) was developed through a rigorous process of forward and back translation, focus-group discussion and piloting. Criterion validation was conducted as part of a larger study in a sample of women who had brought their infants to a child health clinic in rural Malawi, using DSM-IV major and minor depressive episode as the gold standard diagnoses.

RESULTS

The criterion validation was conducted on 114 subjects who did not differ on health and sociodemographic characteristics from the total study sample (n=501). Test characteristics for each possible SRQ cut-off were calculated and Receiver Operator Characteristic (ROC) curves derived. Area under the ROC curve (AUROC) for detection of current major depressive disorder was 0.856 (95% CI 0.813 to 0.900), and for current major or minor depressive disorder was 0.826 (95% CI 0.783 to 0.869). Internal consistency of the SRQ was high (Cronbach's alpha 0.85).

LIMITATION

Inter-rater reliability testing was not conducted.

CONCLUSION

This Chichewa version of the SRQ shows utility as a brief screening measure for detection of probable maternal depression in rural Malawi.

Conflict in the Indian Kashmir Valley II: psychosocial impact

Background

India and Pakistan have disputed ownership of the Kashmir Valley region for many years, resulting in high levels of exposure to violence among the civilian population of Kashmir (India). A survey was done as part of routine programme evaluation to assess confrontation with violence and its consequences on mental health, health service usage, and socio-economic functioning.

Methods

We undertook a two-stage cluster household survey in two districts of Kashmir (India) using questionnaires adapted from other conflict areas. Analysis was stratified for gender.

Results

Over one-third of respondents (n = 510) were found to have symptoms of psychological distress (33.3%, CI: 28.3–38.4); women scoring significantly higher (OR 2.5; CI: 1.7–3.6). A third of respondents had contemplated suicide (33.3%, CI: 28.3–38.4). Feelings of insecurity were associated with higher levels of psychological distress for both genders (males: OR 2.4, CI: 1.3–4.4; females: OR 1.9, CI: 1.1–3.3). Among males, violation of modesty, (OR 3.3, CI: 1.6–6.8), forced displacement, (OR 3.5, CI: 1.7–7.1), and physical disability resulting from violence (OR 2.7, CI: 1.2–5.9) were associated with greater levels of psychological distress; for women, risk factors for psychological distress included dependency on others for daily living (OR 2.4, CI: 1.3–4.8), the witnessing of killing (OR 1.9, CI: 1.1–3.4), and torture (OR 2.1, CI: 1.2–3.7). Self-rated poor health (male: OR 4.4, CI: 2.4–8.1; female: OR 3.4, CI: 2.0–5.8) and being unable to work (male: OR 6.7, CI: 3.5–13.0; female: OR 2.6, CI: 1.5–4.4) were associated with mental distress.

Conclusion

The ongoing conflict exacts a huge toll on the communities' mental well-being. We found high levels of psychological distress that impacts on daily life and places a burden on the health system. Ongoing feelings of personal vulnerability (not feeling safe) was associated with high levels of psychological distress. Community mental health programmes should be considered as a way reduce the pressure on the health system and improve socio-economic functioning of those suffering from mental health problems.

Improving the prevention and management of chronic disease in low-income and middle-income countries: a priority for primary health care

The burden of chronic diseases, such as heart disease, cancer, diabetes, and mental disorders is high in low-income and middle-income countries and is predicted to increase with the ageing of populations, urbanisation, and globalisation of risk factors. Furthermore, HIV/AIDS is increasingly becoming a chronic disorder. An integrated approach to the management of chronic diseases, irrespective of cause, is needed in primary health care. Management of chronic diseases is fundamentally different from acute care, relying on several features: opportunistic case finding for assessment of risk factors, detection of early disease, and identification of high risk status; a combination of pharmacological and psychosocial interventions, often in a stepped-care fashion; and long-term follow-up with regular monitoring and promotion of adherence to treatment. To meet the challenge of chronic diseases, primary health care will have to be strengthened substantially. In the many countries with shortages of primary-care doctors, non-physician clinicians will have a leading role in preventing and managing chronic diseases, and these personnel need appropriate training and continuous quality assurance mechanisms. More evidence is needed about the cost-effectiveness of prevention and treatment strategies in primary health care. Research on scaling-up should be embedded in large-scale delivery programmes for chronic diseases with a strong emphasis on assessment.

Violence, psychological distress and the risk of suicidal behaviour in young people in India

BACKGROUND

Suicide among young people has emerged as a major public health issue in many low- and middle-income (LAMI) countries. Suicidal behaviour including ideation and attempt are the most important predictors of completed suicide and offer critical points for intervention. The aim of this study is to estimate the prevalence and risk factors for suicidal behaviour in young people in India.

METHOD AND FINDINGS

Cross-sectional study of 3662 youth (16-24 years) from rural and urban communities in Goa, India. Suicidal behaviour during the recent 3 months and associated factors were assessed using a structured interview. Overall 144; 3.9% [95% confidence interval (CI) 3.3-4.6] youth reported any suicidal behaviour in the previous 3 months. Suicidal behaviour was found to be associated with female gender Odds ratio (OR) 6.5 (95% CI 3.9-10.8), not attending school or college OR 1.6 (95% CI, 1.01-2.6), independent decision making OR 2.5 (95% CI 1.5-4.3), premarital sex OR 3.2 (95% CI 1.6-6.3), physical abuse at home OR 3.3 (95% CI 1.8-6.1), life time experience of sexual abuse OR 3.3 (95% CI 1.8-6.0) and probable common mental disorders (CMD) OR 9.5 (95% CI 6.3-14.5). Gender segregated analysis found independent decision making (P=0.68 for interaction), rural residence (P=0.01 for interaction) and premarital sex (P=0.41 for interaction) retained association with suicidal behaviour only among females (P<0.05). The population attributable fraction estimates were largest for CMD (42.8% for females; 35.9% for males); physical abuse in one's home (12.5% for females; 12.4% for males); sexual abuse (12.1% in females; 22.3% in males); and making independent decisions (22.9% for females). Analyses of the risk factors for the relatively less common outcome of suicide attempts found a similar set of factors as for suicidal behaviour; in addition, alcohol use was also an independent risk factor.

CONCLUSION

Violence and psychological distress are independently associated with suicidal behaviour; factors associated with gender disadvantage-in particular for rural women, may increase their vulnerabilities. Prevention programs for youth suicide in India need to address both the structural determinants of gender disadvantage, and the individual experiences of violence and poor mental health.

Improving the outcomes of primary care attenders with common mental disorders in developing countries: a cluster randomized controlled trial of a collaborative stepped care intervention in Goa, India

BACKGROUND AND OBJECTIVE

Common mental disorders (CMD) are a leading global burden of disease. Up to 30% of primary care attenders suffer from these disorders but most do not receive evidence-based drug or psychological treatments. There are no trials of interventions which attempt to integrate these treatments into routine primary care in developing countries. The aims of this trial (the MANAS Project) are to evaluate the clinical and cost-effectiveness of a collaborative stepped-care intervention for the treatment of CMD in India.

STUDY DESIGN

A cluster randomized controlled trial will be implemented in the state of Goa, on the west coast of India. Twenty-four primary care facilities, 12 from the government sector and 12 from the private sector, will be enrolled in two consecutive phases. For each sector, facilities will be randomly allocated within strata defined by urban/rural location, population size and presence of a visiting psychiatrist. Facilities will be randomly allocated to receive the collaborative stepped care intervention or the enhanced usual care control intervention. Both arms share two components of the intervention, viz., routine screening, and in the government clinics provision of antidepressants. In addition, the collaborative stepped care arm also provides a range of psychosocial treatments delivered by a specially trained Health Counselor, and supervision by a visiting Psychiatrist. A total of 3600 primary care attenders who are detected to suffer from a CMD based on a validated screening questionnaire will be recruited. The primary outcome is the proportion of subjects who recover from an ICD10 defined CMD at baseline by 6 months. Additional endpoints at 2 and 12 months will assess the speed and sustainability of achieving the primary outcomes. Other outcomes will include recovery from ICD10 defined depression and incidence of ICD-10 among individuals who were sub-threshold cases at baseline. Economic and disability outcomes will be assessed to estimate incremental cost-effectiveness ratios.

IMPLICATIONS

This will be the first trial of the effectiveness of a complex intervention aiming to integrate efficacious treatments for CMD into routine primary care in a developing country. If effective, its findings will have relevance to policy makers who wish to scale up treatments for CMD in primary care across the world, but mostly in those countries where specialist mental health services are few.

STUDY REGISTRATION

The MANAS project is registered through the National Institutes of Health sponsored clinical trials registry and has been assigned the identifier: NCT00446407.
