Cognitive behaviour therapy-based intervention by community health workers for mothers with depression and their infants in rural Pakistan: a cluster-randomised controlled trial

Summary Background The treatment of perinatal depression is a public-health priority because of its high prevalence and association with disability and poor infant development. We integrated a cognitive behaviour therapy-based intervention into the routine work of community-based primary health workers in rural Pakistan and assessed the effect of this intervention on maternal depression and infant outcomes. Methods We randomly assigned 40 Union Council clusters in rural Rawalpindi, Pakistan, in equal numbers to intervention or control. Married women (aged 16–45 years) in their third trimester of pregnancy with perinatal depression were eligible to participate. In the intervention group, primary health workers were trained to deliver the psychological intervention, whereas in the control group untrained health workers made an equal number of visits to the depressed mothers. The primary outcomes were infant weight and height at 6 months and 12 months, and secondary outcome was maternal depression. The interviewers were unaware of what group the participants were assigned to. Analysis was by intention to treat. The study is registered as ISRCTN65316374. Findings The number of clusters per group was 20, with 463 mothers in the intervention group and 440 in the control group. At 6 months, 97 (23%) of 418 and 211 (53%) of 400 mothers in the intervention and control groups, respectively, met the criteria for major depression (adjusted odds ratio (OR) 0·22, 95% CI 0·14 to 0·36, p<0·0001). These effects were sustained at 12 months (111/412 [27%] vs 226/386 [59%], adjusted OR 0·23, 95% CI 0·15 to 0·36, p<0·0001). The differences in weight-for-age and height-for-age Z scores for infants in the two groups were not significant at 6 months (−0·83 vs −0·86, p=0·7 and −2·03 vs −2·16, p=0·3, respectively) or 12 months (−0·64 vs −0·8, p=0·3 and −1·10 vs −1·36, p=0·07, respectively). Interpretation This psychological intervention delivered by community-based primary health workers has the potential to be integrated into health systems in resource-poor settings.

A systematic review of the epidemiology of somatisation disorder and hypochondriasis

BACKGROUND This paper reviews current knowledge regarding the prevalence and associated features of somatisation disorder and hypochondriasis in population-based and primary care samples. METHOD A systematic review of the literature, which used a standardised definition of somatisation disorder or hypochondriasis and which examined the characteristics and associated features of these disorders in population-based samples or primary care settings. RESULTS In population-based studies the prevalence of somatisation disorder and hypochondriasis was too low to examine associated features reliably. In studies using abridged criteria, a clear female predominance was not found in either disorder; there was a consistent relationship with few years of education. There was a close relationship with anxiety and depressive disorders, with a linear relationship between numbers of somatic and other symptoms of distress in several studies, including longitudinal studies. No studies showed that these symptom clusters fulfil the criteria of characteristic onset, course and prognosis required to merit the status of discrete psychiatric disorders. CONCLUSIONS On existing evidence, somatisation disorder and hypochondriasis cannot be regarded as definite psychiatric disorders. There is some evidence that numerous somatic symptoms or illness worry may be associated with impairment and high health care utilisation in a way that cannot be solely explained by concurrent anxiety and depression, but further research using population-based samples is required.

Psychological disorder and severity of inflammatory bowel disease predict health-related quality of life in ulcerative colitis and Crohn's disease

OBJECTIVE:The determinants of health-related quality of life in inflammatory bowel disease are not completely understood. The present study aimed to assess two factors in patients with inflammatory bowel disease: a) whether health-related quality of life is independently associated with both bowel disease severity and psychological disorder, and b) whether Crohns disease is associated with more marked psychological disorder than ulcerative colitis.METHODS:116/170 (68%) consecutive patients with inflammatory bowel disease attending a GI clinic (37 patients with ulcerative colitis, 75 patients with Crohns disease, and four unspecified) completed the following self-report questionnaires: demographic details, a modified disease activity index, a total severity measure, the Hospital Anxiety and Depression Scale, and the Short Form-36.RESULTS:Thirty patients (25.9%) scored 11 or more on either the depression or anxiety subscales of the Hospital Anxiety and Depression Scale indicating probable psychological disorder; 55% (47.4%) scored over 8 indicating possible psychological disorder. Stepwise multiple regression analyses showed that both psychological symptoms and disease severity or activity contributed independently to impaired health-related quality of life. After severity of disease was taken into account, there were no significant differences between Crohns disease and ulcerative colitis in terms of depression scores and health-related quality of life.CONCLUSIONS:The presence of psychological disorder in inflammatory bowel disease contributes to poor health-related quality of life, regardless of the severity of the condition. Detection and treatment of psychological disorder in inflammatory bowel disease carries the potential to improve health-related quality of life for these patients.

Embarking upon a medical career: psychological morbidity in first year medical students

This study was undertaken to measure the prevalence of psychological morbidity, and the nature and source of stress, in first year medical students. Two hundred and four first year medical students at a university in the north of England were sent a postal, self‐report questionnaire. They were asked to complete the General Health Questionnaire (GHQ), the Stress Incident Record and to give details of their alcohol consumption. A total of 172 students (84·3%) replied. Thirty‐six per cent of the students scored above the threshold of the GHQ, indicating probable psychological disturbance. There was no difference between men and women. Approximately half of the students described a stressful incident, the majority of which were related to medical training rather than to personal problems. Male students reported drinking significantly more alcohol than female students, but there was no relationship between levels of alcohol consumption and either psychological disturbance or reporting of stress.

Depression and social stress in Pakistan

BACKGROUND The high prevalence of depression in developing countries is not well understood. This study aimed to replicate the previous finding of a high prevalence of depression in Pakistan and assess in detail the associated social difficulties. METHOD A two-phase survey of a general population sample in a Pakistani village was performed. The first-phase screen used the Personal Health Questionnaire (PHQ) and the self-rating questionnaire (SRQ). A one in two sample of high scorers and a one in three sample of the low scorers were interviewed using the Psychiatric Assessment Schedule (PAS) and Life Events and Difficulties Schedule (LEDS). RESULTS A total of 259 people were screened (96% response rate). The second stage yielded 55 cases, of whom 54 had depressive disorder, and 48 non-cases. The adjusted prevalence of depressive disorders was 44-4% (95% CI 35.3 to 53.6): 25.5% in males and 57.5% in females. Nearly all cases had lasted longer than 1 year. Comparison of the cases and non-cases indicated that cases were less well educated, had more children and experienced more marked, independent chronic difficulties. Multivariate analysis indicated that severe financial and housing difficulties, large number of children and low educational level were particularly closely associated with depression. CONCLUSION This study confirms the high prevalence of depressive disorders in Pakistan and suggests that this may be higher than other developing countries because of the high proportion of the population who experience social adversity.

A randomised controlled trial of cognitive behaviour therapy and motivational interviewing for people with Type 1 diabetes mellitus with persistent sub-optimal glycaemic control: a Diabetes and Psychological Therapies (ADaPT) study.

OBJECTIVES To determine whether (i) motivational enhancement therapy (MET) + cognitive behaviour therapy (CBT) compared with usual care, (ii) MET compared with usual care, (iii) or MET + CBT compared with MET was more effective in improving glycaemic control when delivered by general nurses with additional training in these techniques. DESIGN A three-arm parallel randomised controlled trial as the gold standard design to test the effectiveness of psychological treatments. SETTING The recruiting centres were diabetes clinics in seven acute trusts in south-east London and Greater Manchester. PARTICIPANTS Adults (18-65 years) with a confirmed diagnosis of type 1 diabetes for a minimum duration of 2 years and a current glycated (or glycosylated) haemoglobin (HbA1c) value between 8.2% and 15.0%. INTERVENTIONS The control arm consisted of usual diabetes care which varied between the hospitals, but constituted at least three monthly appointments to diabetes clinic. The two treatments arms consisted of usual care with MET and usual care with MET + CBT. MAIN OUTCOME MEASURES The primary outcome was HbA1c at 12 months from randomisation. Secondary outcome measures were 1-year costs measured by the Client Service Receipt Inventory at baseline, 6 months and 12 months; quality of life-years [quality-adjusted life-years (QALYs)] measured by the SF-36 (Short Form-36 Health Survey Questionnaire) and EQ-5D (European Quality of Life-5 Dimensions) at baseline and 12 months. RESULTS One thousand six hundred and fifty-nine people with type 1 diabetes were screened and 344 were randomised to MET + CBT (n = 106), MET (n = 117) and to usual care (n = 121). The 12-month follow-up rate for HbA1c was 88% (n = 305). The adjusted mean 12-month HbA1c was 0.45% lower in those treated with MET + CBT [95% confidence interval (CI) 0.16% to 0.79%, p = 0.008] than for usual care; 0.16% lower in those treated with MET (95% CI 0.20% to 0.51%, p = 0.38) than for usual care; and 0.30% lower with MET + CBT than with MET (95% CI -0.07% to 0.66%, p = 0.11). The higher the HbA1c, and the younger the participant at baseline, the greater was the reduction in HbA1c. The interventions had no effect on secondary outcomes such as depression and quality of life. The economic evaluation was inconclusive. Both interventions were associated with increased health care costs than for usual care alone. There was no significant difference in social costs. Cost effectiveness ratios, up to one year, varied considerably according to whether QALY estimates were based on EQ-5D or SF-36 and whether imputed or complete data were used in the analyses. CONCLUSIONS A combination of MET and CBT may be useful for patients with persistent sub-optimal diabetic control. MET alone appears less effective than usual care. Economic evaluation was inconclusive. TRIAL REGISTRATION Current Controlled Trials ISRCTN77044517.

DEPRESSION, COGNITIVE IMPAIRMENT AND SOCIAL STRESS IN MULTIPLE SCLEROSIS

Twenty-four out-patients with established multiple sclerosis (MS) who had been neurologically assessed underwent detailed psychiatric, cognitive and social assessments. Depression was associated with significant cognitive impairment and with social stress but not with degree of neurological impairment, specific neurological symptoms, disability or handicap. It is suggested that depression in relapsing-remitting MS may arise when cognitive deficits cause problems in occupational performance and impinge on close personal relationships.

Maternal depression increases infant risk of diarrhoeal illness: –a cohort study

Aims: To examine the associations between postnatal depression in mothers and diarrhoeal illness in their infants in the first year of life in a low-income country. Methods: Using a prospective cohort design, 265 infants (n = 130 of mothers having a depressive episode according to the International Classification of Diseases, 10th revision, at 3 months postnatal and n = 135 of psychologically well mothers) living in rural Rawalpindi, Pakistan, were followed up for 1 year. Frequency of diarrhoeal episodes was measured fortnightly by health workers using a standard questionnaire. Results: Infants of depressed mothers had significantly more diarrhoeal episodes per year than those of controls (mean 5.5 v 4.0; 95% confidence interval (CI) 0.9 to 2.0). The relative risk of having ⩾5 diarrhoeal episodes per year in infants of depressed mothers was 2.3 (95% CI 1.6 to 3.1). The association remained significant after adjustment for other risk factors by multivariate analysis. Conclusions: Maternal depression is associated with infant diarrhoeal morbidity in a low-income community setting. It is independent of the effects of known factors such as undernutrition, socioeconomic status and parental education. Preventive child health programmes targeting mothers must consider their mental health.

Psychosocial predictors of health-related quality of life and health service utilisation in people with chronic low back pain

&NA; Psychological and social factors have been shown, separately, to predict outcome in individuals with chronic low back pain. Few previous studies, however, have integrated both psychological and social factors, using prospective study of clinic populations of low back pain patients, to identify which are the most important targets for treatment. One hundred and eight patients with chronic low back pain, newly referred to an orthopaedic outpatient clinic, completed assessments of demographic characteristics, details of back pain, measures of anxiety and depression (Hospital Anxiety and Depression Scale, HADS), fearful beliefs about pain (Fear Avoidance Beliefs Questionnaire), social stresses (Life Events and Difficulties Schedule) and physical aspects of health‐related quality of life [SF‐36 Physical Component summary Score scale (PCS)]. Six months later subjects completed the SF‐36 PCS and the number of healthcare contacts during follow‐up was recorded. Independent predictors of SF‐36 PCS at 6‐month follow‐up were duration of pain [(standardised regression coefficient (β) = −0.18, p = 0.04), HADS score (β) = −0.27, p = 0.003] and back pain related social difficulties (β = −0.42, p < 0.0005). Number of healthcare contacts over the 6 months ranged from 1 to 29, and was independently predicted by perceived cause of pain [Incident Rate Ratio (IRR) = 1.46, p = 0.03], Fear Avoidance Beliefs about work (IRR = 1.02, p = 0.009) and back pain related social difficulties (IRR = 1.16, p = 0.03). To conclude, anxiety, depression, fear avoidance beliefs relating to work and back pain related stresses predict impairment in subsequent physical health‐related quality of life and number of healthcare contacts. Interventions targeting these psychosocial variables in clinic patients may lead to improved quality of life and healthcare costs.
