Intervention for minor depression in primary care patients

Depression and suicidal ideation: association of physical, mental, social, and spiritual health status

PURPOSE

The aim of this study was to determine if multidimensional (physical, mental, social, spiritual) health status could predict the presence of depressive symptoms and suicidal ideation in the general population.

METHODS

We administered a population-based, cross-sectional survey to 1200 participants from the general Korean population. The survey included the 5 Health Status Questionnaire (5HSQ) for self-rated health status, Patient Health Questionnaire-9 (PHQ-9) for depression, and a question from the PHQ-9 for suicidal ideation. Multiple logistic regression was performed to estimate the association of significant socio-demographic factors and self-rated health status with depression and suicidal ideation.

RESULTS

Physical health status was associated with depression in both men and women (men: adjusted odds ratio [aOR], 4.69; 95% confidence interval [CI] 2.44-9.00; women: aOR, 2.05; 95% CI 1.13-3.72) while spiritual health status only affected men (aOR, 5.50; 95% CI 2.59-11.65) and mental health status only women (aOR, 3.92; 95% CI 2.03-7.54). Social health status was associated with suicidal ideation in men (aOR, 4.87; 95% CI 2.74-19.99) while mental health status was associated with suicidal ideation in women (aOR, 4.31; 95% CI 1.90-9.76).

CONCLUSION

Physical, mental, social, and spiritual self-rated health statuses were all found to be associated with an individual's predisposition to depression and suicidal ideation with notable differences between men and women.

Implications of Epidemiological Findings for the Management of Mental Disorders Encountered in Primary Care Settings

Recent epidemiological surveys that have attempted to include the need for treatment of mental disorders are reviewed, and it is concluded that the greatest unmet need is for those with non-psychotic disorders. Recent studies on factors that influence the natural history of such disorders reveal that these are largely social and environmental; one study suggests that genetic factors are only important in the group that have longer time courses. Those factors within the medical encounter that produce better outcomes are reviewed, and non-specific factors and supportive therapy are found to be important. Some additional advantages are to be obtained with specific antidepressant treatments (either pharmacological or problem-solving) and with re-attribution skills for psychologically determined somatic symptoms. The implications of these findings are discussed from the standpoint of the primary care team, the community mental health team and self-help materials.

Determine the relationship between perceived social support and depression level of patients with diabetic foot

Background

As a lifelong disease, diabetes impairs the quality of life by limiting the eating and drinking habits and by bringing out the risk of kidney, eye, cardiovascular and diabetic neurological diseases in the long run. Loss of health might result in mourning, grief, rebellion, denial, anxiety, rage and sometimes these feelings might overcome the patient’s coping skills leading to depression [Clinical Psychiatry 11 (Suppl 3) 3-18, 2008]. How individuals suffering from depression perceive and interpret the incidents around them is also important [Rel. Scie. Acad. J. III, 2: 129-152, 2003]. Accordingly, the determination of the correlation of the depression with the perceived social support level by the patients with diabetic foot was programmed and performed in order to take essential precautions, to generate proper solutions and treatment process and to make supportive plans for patients with developing diabetic foot and depression.

Methods

The data was obtained from 128 patients who applied to hospital within the scope of research between July 1st 2011 and January 31st 2012 that were diagnosed with diabetes and had diabetic foot. Pearson chi-square, Fisher Exact and Likelihood ratio, chi-square, Student t test and one way analysis of variance, Levene’ s test, One way ANOVA, Welch and Games Howell tests were used in the analysis and evaluation. The data was collected by meeting face to face the individuals and by making use of the patient files and using the “Personal Information Form” which includes introductory information about individuals with diabetic foot, “Beck Depression Scale” which is applied to determine emotion status of individuals and “Multidimensional Scale of Perceived Social Support” which is applied to determine the level of social support individuals perceive.

Results

In the performed statistical evaluation, mean scores of Beck Depression scale and MSPSS family support, friend support, special person support sub-dimension and scale total scores were found to be in negative statistical correlation (p < 0.01).

Conclusions

In the treatment and care of the patients with diabetic foot; anxiety and depression status of the patients, as well as physical status, should also be evaluated routinely. The individuals provided to take professional care.

Sequential screening for psychosocial and behavioural risk during pregnancy in a population of urban African Americans

OBJECTIVE

Screening for psychosocial and behavioural risks, such as depression, intimate partner violence, and smoking, during pregnancy is considered to be state of the art in prenatal care. This prospective longitudinal analysis examines the added benefit of repeated screening, compared with a single screening, in identifying such risks during pregnancy.

DESIGN

Data were collected as part of a randomised controlled trial to address intimate partner violence, depression, smoking, and environmental tobacco smoke exposure in African American women.

SETTING

Prenatal care sites in the District of Columbia serving mainly women of minority background.

POPULATION

A cohort of 1044 African American pregnant women in the District of Columbia.

METHODS

Mothers were classified by their initial response (acknowledgement of risks), and these data were updated during pregnancy. Risks were considered new if they were not previously reported. Standard hypothesis tests and logistic regression were used to predict the acknowledgment of any new risk(s) during pregnancy.

MAIN OUTCOME MEASURES

New risks: psychosocial variables to understand what factors might help identify the acknowledgement of additional risk(s).

RESULTS

Repeated screening identified more mothers acknowledging risk over time. Reported smoking increased by 11%, environmental tobacco smoke exposure increased by 19%, intimate partner violence increased by 9%, and depression increased by 20%. The psychosocial variables collected at the baseline that were entered into the logistic regression model included relationship status, education, Medicaid, illicit drug use, and alcohol use during pregnancy. Among these, only education less than high school was associated with the acknowledgement of new risk in the bivariate analyses, and significantly predicted the identification of new risks (OR 1.39, 95% CI 1.01-1.90).

CONCLUSIONS

It is difficult to predict early on who will acknowledge new risks over the course of pregnancy, and thus all women should be screened repeatedly to allow for the identification of risks and intervention during prenatal care.

Is the cognitive-behavioral therapy an effective intervention to prevent the postnatal depression? A critical review

OBJECTIVE

The aim of this article is to review and discuss the efficacy of the Cognitive-Behavioral Therapy (CBT), in the prevention of postnatal depression (PD) in pregnant women at risk.

METHOD

PubMed, Medline, PsychInfo, Embase, and the Cochrane Library databases were searched from February 1991 to February 2011.

RESULTS

Eight Randomized Controlled Trials (RCT) on the prevention of PD with the CBT were selected and their data were analyzed. The literature analyzed recommends that depression in pregnancy requires an efficient management to provide mother's symptoms relief as well as to prevent the PD. While several studies demonstrated the efficacy of the CBT in the treatment of PD, the efficacy of the CBT in preventing PD in pregnant women at risk has been investigated only by a few studies, presenting a number of methodological flaws.

CONCLUSIONS

Better designed RCT are needed to support the efficacy of such psychotherapeutic preventive strategy in women at risk for PD.

Are there meaningful differences between major depressive disorder, dysthymic disorder, and their subthreshold variants?

A number of researchers have proposed adding an increasing number of subthreshold variants of major depressive disorder (MDD) as new mood disorder. However, this research has suffered from a number of theoretical and methodological flaws that the current investigation has attempted to address. Individuals with MDD (n = 470) were compared with individuals with subthreshold MDD (n = 57). Individuals with MDD reported consistently more severe symptoms, albeit of small magnitude, as well as differences in comorbidity with only two disorders. Results also indicated that diagnosis did not significantly predict rate of symptom change when MDD was compared with its subthreshold variant. Taken together, the aforementioned evidence suggests that small differences exist between MDD and its subthreshold variant. In addition, the extent to which the latter serves as useful analogs for the former may depend upon the variables under study.

An integrated randomized intervention to reduce behavioral and psychosocial risks: pregnancy and neonatal outcomes

While biomedical risks contribute to poor pregnancy and neonatal outcomes in African American (AA) populations, behavioral and psychosocial risks (BPSR) may also play a part. Among low income AA women with psychosocial risks, this report addresses the impacts on pregnancy and neonatal outcomes of an integrated education and counseling intervention to reduce BPSR, as well as the contributions of other psychosocial and biomedical risks. Subjects were low income AA women ≥18 years living in the Washington, DC, metropolitan area and seeking prenatal care. Subjects (n = 1,044) were screened for active smoking, environmental tobacco smoke exposure (ETSE), depression, or intimate partner violence (IPV) and then randomized to intervention (IG) or usual care (UCG) groups. Data were collected prenatally, at delivery, and postpartum by maternal report and medical record abstraction. Multiple imputation methodology was used to estimate missing variables. Rates of pregnancy outcomes (miscarriage, live birth, perinatal death), preterm labor, Caesarean section, sexually transmitted infection (STI) during pregnancy, preterm birth (<37 weeks), low birth weight (<2,500 g), very low birth weight (<1,500 g), small for gestational age, neonatal intensive care unit (NICU) admission, and >2 days of hospitalization were compared between IG and UCG. Logistic regression models were created to predict outcomes based on biomedical risk factors and the four psychosocial risks (smoking, ETSE, depression, and IPV) targeted by the intervention. Rates of adverse pregnancy and neonatal outcomes were high and did not differ significantly between IG and UCG. In adjusted analysis, STI during the current pregnancy was associated with IPV (OR = 1.41, 95% CI 1.04-1.91). Outcomes such as preterm labor, caesarian section in pregnancy and preterm birth, low birth weight, small for gestational age, NICU admissions and >2 day hospitalization of the infants were associated with biomedical risk factors including preexisting hypertension and diabetes, previous preterm birth (PTB), and late initiation of prenatal care, but they were not significantly associated with active smoking, ETSE, depression, or IPV. Neither the intervention to reduce BPSR nor the psychosocial factors significantly contributed to the pregnancy and neonatal outcomes. This study confirms that biomedical factors significantly contribute to adverse outcomes in low income AA women. Biomedical factors outweighed psychosocial factors in contributing to adverse pregnancy and neonatal outcomes in this high-risk population. Early identification and management of hypertension, diabetes and previous PTB in low income AA women may reduce health disparities in birth outcomes. Level of evidence I.

Counselling for mental health and psychosocial problems in primary care

BACKGROUND

The prevalence of mental health and psychosocial problems in primary care is high. Counselling is a potential treatment for these patients, but there is a lack of consensus over the effectiveness of this treatment in primary care.

OBJECTIVES

To assess the effectiveness and cost effectiveness of counselling for patients with mental health and psychosocial problems in primary care.

SEARCH STRATEGY

To update the review, the following electronic databases were searched: the Cochrane Collaboration Depression, Anxiety and Neurosis (CCDAN) trials registers (to December 2010), MEDLINE, EMBASE, PsycINFO and the Cochrane Central Register of Controlled Trials (to May 2011).

SELECTION CRITERIA

Randomised controlled trials of counselling for mental health and psychosocial problems in primary care.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised data extraction sheet by two reviewers. Trials were rated for quality by two reviewers using Cochrane risk of bias criteria, to assess the extent to which their design and conduct were likely to have prevented systematic error. Continuous measures of outcome were combined using standardised mean differences. An overall effect size was calculated for each outcome with 95% confidence intervals (CI). Continuous data from different measuring instruments were transformed into a standard effect size by dividing mean values by standard deviations. Sensitivity analyses were undertaken to test the robustness of the results. Economic analyses were summarised in narrative form. There was no assessment of adverse events.

MAIN RESULTS

Nine trials were included in the review, involving 1384 randomised participants. Studies varied in risk of bias, although two studies were identified as being at high risk of selection bias because of problems with concealment of allocation. All studies were from primary care in the United Kingdom and thus comparability was high. The analysis found significantly greater clinical effectiveness in the counselling group compared with usual care in terms of mental health outcomes in the short-term (standardised mean difference -0.28, 95% CI -0.43 to -0.13, n = 772, 6 trials) but not in the long-term (standardised mean difference -0.09, 95% CI -0.27 to 0.10, n = 475, 4 trials), nor on measures of social function (standardised mean difference -0.09, 95% CI -0.29 to 0.11, n = 386, 3 trials). Levels of satisfaction with counselling were high. There was some evidence that the overall costs of counselling and usual care were similar. There were limited comparisons between counselling and other psychological therapies, medication, or other psychosocial interventions.

AUTHORS' CONCLUSIONS

Counselling is associated with significantly greater clinical effectiveness in short-term mental health outcomes compared to usual care, but provides no additional advantages in the long-term. Participants were satisfied with counselling. Although some types of health care utilisation may be reduced, counselling does not seem to reduce overall healthcare costs. The generalisability of these findings to settings outside the United Kingdom is unclear.

The Role of Maternal Depression on Treatment Outcome for Children with Externalizing Behavior Problems

Studies have shown that, on average, Parent Management Training combined with cognitive-behavioral therapy decreases children’s externalizing behavior, but some children do not improve through treatment. The current study aimed to examine the role of maternal depression in understanding this variability in treatment outcome. Children with externalizing behavioral problems and their parents were recruited from combined Parent Management Training and Cognitive-Behavioral programs in “real-world” clinical settings. At pre- and post treatment, maternal depression and children’s externalizing behavior were assessed. Results showed that treatment was less effective for children of depressed mothers compared to non-depressed mothers and that improvements in maternal depression were associated with improvements in children’s externalizing behavior. These findings suggest that treatment programs for children with externalizing problems may be able to improve outcomes if maternal depression is a target of intervention.

Very preterm birth is reduced in women receiving an integrated behavioral intervention: a randomized controlled trial

This study examines whether an integrated behavioral intervention with proven efficacy in reducing psycho-behavioral risks (smoking, environmental tobacco smoke exposure (ETSE), depression, and intimate partner violence (IPV)) in African-Americans is associated with improved pregnancy outcomes. A randomized controlled trial targeting risks during pregnancy was conducted in the District of Columbia. African-American women were recruited if reporting at least one of the risks mentioned above. Randomization to intervention or usual care was site and risk specific. Sociodemographic, health risk and pregnancy outcome data were collected. Data on 819 women, and their singleton live born infants were analyzed using an intent-to-treat approach. Bivariate analyses preceded a reduced logistical model approach to elucidate the effect of the intervention on the reduction of prematurity and low birth weight. The incidence of low birthweight (LBW) was 12% and very low birthweight (VLBW) was 1.6%. Multivariate logistic regression results showed that depression was associated with LBW (OR = 1.71, 95% CI = 1.12-2.62). IPV was associated with preterm birth (PTB) and very preterm birth (VPTB) (OR 1.64, 95% CI = 1.07-2.51, OR = 2.94, 95% CI = 1.40-6.16, respectively). The occurrence of VPTB was significantly reduced in the intervention compared to the usual care group (OR = 0.42, 95% CI = 0.19-0.93). Our study confirms the significant associations between multiple psycho-behavioral risks and poor pregnancy outcomes, including LBW and PTB. Our behavioral intervention with demonstrated efficacy in addressing multiple risk factors simultaneously reduced VPTB within an urban minority population.

Influence of caregiver burden on the association between daily fluctuations in pleasant activities and mood: A daily diary analysis

Much research has focused on behavioral activation and its effect on depression, but less is known about the effects of leisure activities on the two distinct affective domains of depression: positive affect (PA) and negative affect (NA). Furthermore, individual factors (i.e., stress level) may moderate the impact of behavioral activation on affect. The present study utilized a daily diary approach to examine the moderating effect of stress on the relationship between leisure satisfaction and both PA and NA. Twenty-five dementia caregivers completed activity and affect measures four times daily for 14 days. Results were analyzed using multilevel modeling, an approach that considers intra-individual differences in activity and affect over time. Results supported the hypothesis that caregivers with higher burden display a stronger association between leisure satisfaction and affect than caregivers with lower burden. Specifically, caregivers with higher burden had a stronger positive relationship between leisure satisfaction and PA and a stronger negative relationship between leisure satisfaction and NA. These findings suggest that screening caregivers for level of burden may help identify those most likely to benefit from behavioral interventions.

An integrated intervention to reduce intimate partner violence in pregnancy: a randomized controlled trial

OBJECTIVE

To estimate the efficacy of a psycho-behavioral intervention in reducing intimate partner violence recurrence during pregnancy and postpartum and in improving birth outcomes in African-American women.

METHODS

We conducted a randomized controlled trial for which 1,044 women were recruited. Women were randomly assigned to receive either intervention (n=521) or usual care (n=523). Individually tailored counseling sessions were adapted from evidence-based interventions for intimate partner violence and other risks. Logistic regression was used to model intimate partner violence victimization recurrence and to predict minor, severe, physical, and sexual intimate partner violence.

RESULTS

Women randomly assigned to the intervention group were less likely to have recurrent episodes of intimate partner violence victimization (odds ratio [OR] 0.48, 95% confidence interval [CI] 0.29-0.80). Women with minor intimate partner violence were significantly less likely to experience further episodes during pregnancy (OR 0.48, 95% CI 0.26-0.86, OR 0.53, 95% CI 0.28-0.99) and postpartum (OR 0.56, 95% CI 0.34-0.93). Numbers needed to treat were 17, 12, and 22, respectively, as compared with the usual care group. Women with severe intimate partner violence showed significantly reduced episodes postpartum (OR 0.39, 95% CI 0.18-0.82); the number needed to treat was 27. Women who experienced physical intimate partner violence showed significant reduction at the first follow-up (OR 0.49, 95% CI 0.27-0.91) and postpartum (OR 0.47, 95% CI 0.27-0.82); the numbers needed to treat were 18 and 20, respectively. Women in the intervention group had significantly fewer very preterm neonates (1.5% intervention group, 6.6% usual care group; P=.03) and an increased mean gestational age (38.2+/-3.3 intervention group, 36.9+/-5.9 usual care group; P=.016).

CONCLUSION

A relatively brief intervention during pregnancy had discernible effects on intimate partner violence and pregnancy outcomes. Screening for intimate partner violence as well as other psychosocial and behavioral risks and incorporating similar interventions in prenatal care is strongly recommended.

Disparities in detection and treatment history among mothers with major depression in Los Angeles

OBJECTIVE

We sought to determine disparities in detection and treatment histories among a group of racial and ethnically diverse mothers with major depression.

METHOD

Our sample included 276 racially and ethnically diverse mothers who participated in the Los Angeles Family and Neighborhood Survey and who were classified with major depression based on the Comprehensive International Diagnostic Interview-Short Form. We used logistic regression to assess the association between demographic factors and previous detection with major depression, mental health specialty use, and the use of a primary care physician among these women. The demographic factors examined included race and ethnicity, immigration status, marital status, education, income, body mass index (BMI), maternal age, number of children, children's ages, history of emotional problems, and history of diabetes.

RESULTS

Results indicated that 69% of mothers had not been previously detected with major depression nor had they sought mental health treatment in the 12 months before the interview. The odds of having been previously diagnosed with major depression were significantly higher among White and single mothers, as well as among mothers with higher BMIs and those with a history of emotional problems. Nonimmigrant mothers without emotional problems had a higher odds of having seen a mental health specialist in the 12 months before the interview compared with immigrant mothers without emotional problems; no differences in mental health treatment were found between nonimmigrant and immigrant mothers with emotional problems. Finally, African-American mothers and those with a history of diabetes had significantly higher odds of seeing a primary care physician compared with Hispanic mothers and those with no history of diabetes, respectively.

CONCLUSION

Our analyses of a population of depressed mothers living in Los Angeles highlight the need for identification and treatment of racial minority and immigrant mothers.

Reducing psychosocial and behavioral pregnancy risk factors: results of a randomized clinical trial among high-risk pregnant african american women

OBJECTIVES

We evaluated the efficacy of a primary care intervention targeting pregnant African American women and focusing on psychosocial and behavioral risk factors for poor reproductive outcomes (cigarette smoking, secondhand smoke exposure, depression, and intimate partner violence).

METHODS

Pregnant African American women (N = 1044) were randomized to an intervention or usual care group. Clinic-based, individually tailored counseling sessions were adapted from evidence-based interventions. Follow-up data were obtained for 850 women. Multiple imputation methodology was used to estimate missing data. Outcome measures were number of risks at baseline, first follow-up, and second follow-up and within-person changes in risk from baseline to the second follow-up.

RESULTS

Number of risks did not differ between the intervention and usual care groups at baseline, the second trimester, or the third trimester. Women in the intervention group more frequently resolved some or all of their risks than did women in the usual care group (odds ratio = 1.61; 95% confidence interval = 1.08, 2.39; P = .021).

CONCLUSIONS

In comparison with usual care, a clinic-based behavioral intervention significantly reduced psychosocial and behavioral pregnancy risk factors among high-risk African American women receiving prenatal care.

On-site mental health workers delivering psychological therapy and psychosocial interventions to patients in primary care: effects on the professional practice of primary care providers

BACKGROUND

Mental health problems are common in primary care and mental health workers (MHWs) are increasingly working in this setting delivering psychological therapy and psychosocial interventions to patients. In addition to treating patients directly, the introduction of on-site MHWs represents an organisational change that may lead to changes in the clinical behaviour of primary care providers (PCPs).

OBJECTIVES

To assess the effects of on-site MHWs delivering psychological therapy and psychosocial interventions in primary care on the clinical behaviour of primary care providers (PCPs).

SEARCH STRATEGY

The following sources were searched in 1998: the Cochrane Effective Practice and Organisation of Care Group Specialised Register, the Cochrane Controlled Trials Register, MEDLINE, EMBASE, PsycINFO, CounselLit, NPCRDC skill-mix in primary care bibliography, and reference lists of articles. Additional searches were conducted in February 2007 using the following sources: MEDLINE, EMBASE, PsycINFO, CINAHL, and Cochrane Central Register of Clinical Trials (CENTRAL) (The Cochrane Library).

SELECTION CRITERIA

Randomised trials, controlled before and after studies, and interrupted time series analyses of MHWs working alongside PCPs in primary care settings. The outcomes included objective measures of PCP behaviours such as consultation rates, prescribing, and referral.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed study quality.

MAIN RESULTS

Forty-two studies were included in the review. There was evidence that MHWs caused significant reductions in PCP consultations (standardised mean difference -0.17, 95% CI -0.30 to -0.05), psychotropic prescribing (relative risk 0.67, 95% CI 0.56 to 0.79), prescribing costs (standardised mean difference -0.22, 95% CI -0.38 to -0.07), and rates of mental health referral (relative risk 0.13, 95% CI 0.09 to 0.20) for the patients they were seeing. In controlled before and after studies, the addition of MHWs to a practice did not affect prescribing behaviour towards the wider practice population and there was no consistent pattern to the impact on referrals in the wider patient population.

AUTHORS' CONCLUSIONS

This review provides some evidence that MHWs working in primary care to deliver psychological therapy and psychosocial interventions cause a significant reduction in PCP behaviours such as consultations, prescribing, and referrals to specialist care. However, the changes are modest in magnitude, inconsistent, do not generalise to the wider patient population, and their clinical or economic significance is unclear.

An intervention to improve postpartum outcomes in African-American mothers: a randomized controlled trial

OBJECTIVE

To evaluate the efficacy of an integrated multiple risk intervention, delivered mainly during pregnancy, in reducing such risks (cigarette smoking, environmental tobacco smoke exposure, depression, and intimate partner violence) postpartum.

METHODS

Data from this randomized controlled trial were collected prenatally and on average 10 weeks postpartum in six prenatal care sites in the District of Columbia. African Americans were screened, recruited, and randomly assigned to the behavioral intervention or usual care. Clinic-based, individually tailored counseling was delivered to intervention women. The outcome measures were number of risks reported postpartum and reduction of these risks between baseline and postpartum.

RESULTS

The intervention was effective in significantly reducing the number of risks reported in the postpartum period. In bivariate analyses, the intervention group was more successful in resolving all risks (47% compared with 35%, P=.007, number needed to treat=9, 95% confidence interval [CI] 5-31) and in resolving some risks (63% compared with 54%, P=.009, number needed to treat=11, 95% CI 7-43) as compared with the usual care group. In logistic regression analyses, women in the intervention group were more likely to resolve all risks (odds ratio 1.86, 95% CI 1.25-2.75, number needed to treat=7, 95% CI 4-19) and resolve at least one risk (odds ratio 1.60, 95% CI 1.15-2.22, number needed to treat=9, 95% CI 6-29).

CONCLUSION

An integrated multiple risk factor intervention addressing psychosocial and behavioral risks delivered mainly during pregnancy can have beneficial effects in risk reduction postpartum.

The design, implementation and acceptability of an integrated intervention to address multiple behavioral and psychosocial risk factors among pregnant African American women

BACKGROUND

African American women are at increased risk for poor pregnancy outcomes compared to other racial-ethnic groups. Single or multiple psychosocial and behavioral factors may contribute to this risk. Most interventions focus on singular risks. This paper describes the design, implementation, challenges faced, and acceptability of a behavioral counseling intervention for low income, pregnant African American women which integrated multiple targeted risks into a multi-component format.

METHODS

Six academic institutions in Washington, DC collaborated in the development of a community-wide, primary care research study, DC-HOPE, to improve pregnancy outcomes. Cigarette smoking, environmental tobacco smoke exposure, depression and intimate partner violence were the four risks targeted because of their adverse impact on pregnancy. Evidence-based models for addressing each risk were adapted and integrated into a multiple risk behavior intervention format. Pregnant women attending six urban prenatal clinics were screened for eligibility and risks and randomized to intervention or usual care. The 10-session intervention was delivered in conjunction with prenatal and postpartum care visits. Descriptive statistics on risk factor distributions, intervention attendance and length (i.e., with < 4 sessions considered minimal adherence) for all enrolled women (n = 1,044), and perceptions of study participation from a sub-sample of those enrolled (n = 152) are reported.

RESULTS

Forty-eight percent of women screened were eligible based on presence of targeted risks, 76% of those eligible were enrolled, and 79% of those enrolled were retained postpartum. Most women reported a single risk factor (61%); 39% had multiple risks. Eighty-four percent of intervention women attended at least one session (60% attended > or = 4 sessions) without disruption of clinic scheduling. Specific risk factor content was delivered as prescribed in 80% or more of the sessions; 78% of sessions were fully completed (where all required risk content was covered). Ninety-three percent of the subsample of intervention women had a positive view of their relationship with their counselor. Most intervention women found the session content helpful. Implementation challenges of addressing multiple risk behaviors are discussed.

CONCLUSION

While implementation adjustments and flexibility are necessary, multiple risk behavioral interventions can be implemented in a prenatal care setting without significant disruption of services, and with a majority of referred African American women participating in and expressing satisfaction with treatment sessions.

The care of patients with subthreshold depression in primary care: is it all that bad? A qualitative study on the views of general practitioners and patients

BACKGROUND

Studies show that subthreshold depression is highly prevalent in primary care, has impact on the quality of life and causes immense health care costs. Although this points to the clinical relevance of subthreshold depression, contradictory results exist regarding the often self-remitting course of this state. However, first steps towards quality improvement in the care of subthreshold depressive patients are being undertaken. This makes it important to gather information from both a GPs' and a patients' point of view concerning the clinical relevance as well as the status quo of diagnosis and treatment in order to appraise the need for quality improvement research.

METHOD

We conducted qualitative, semi-structured interviews for the questioning of 20 GPs and 20 patients with subthreshold depression on aspects of clinical relevance and on the status quo of diagnosis and treatment. Interviews were transcribed and analyzed on a content analytical theoretical background using Atlas.ti software.

RESULTS

Most of the GPs found subthreshold depression to be clinically significant. Although some problems in diagnosis and treatment were mentioned, the GPs had sensible diagnostic and treatment strategies at hand which resulted from the long and trustful relationship with the patients and which corresponded to the patients' expectations. The patients rather expected their GP to listen to them than to take specific actions towards symptom relief and, in the main, were satisfied with the GPs' care.

CONCLUSION

The study shows that subthreshold depression is a clinically relevant issue for GPs but raises the possibility that quality improvement might not be as necessary as past studies showed. Further quantitative research using larger random samples is needed to determine the effectiveness of the strategies used by the GPs, patients' satisfaction with these strategies and the course of these patients' symptoms in primary care.

Effectiveness of a time-limited cognitive behavior therapy type intervention among primary care patients with medically unexplained symptoms

PURPOSE

Patients seeking care for medically unexplained physical symptoms pose a major challenge at primary care sites, and there are very few well-accepted and properly evaluated interventions to manage such patients.

METHODS

We tested the effectiveness of a cognitive behavior therapy (CBT)-type intervention delivered in primary care for patients with medically unexplained physical symptoms. Patients were randomly assigned to receive either the intervention plus a consultation letter or usual clinical care plus a consultation letter. Physical and psychiatric symptoms were assessed at baseline, at the end of treatment, and at a 6-month follow-up. All treatments and assessments took place at the same primary care clinic where patients sought care.

RESULTS

A significantly greater proportion of patients in the intervention group had physical symptoms rated by clinicians as "very much improved" or "much improved" compared with those in the usual care group (60% vs 25.8%; odds ratio = 4.1; 95% confidence interval, 1.9-8.8; P<.001). The intervention's effect on unexplained physical symptoms was greatest at treatment completion, led to relief of symptoms in more than one-half of the patients, and persisted months after the intervention, although its effectiveness gradually diminished. The intervention also led to significant improvements in patient-reported levels of physical symptoms, patient-rated severity of physical symptoms, and clinician-rated depression, but these effects were no longer noticeable at follow-up.

CONCLUSIONS

This time-limited, CBT-type intervention significantly ameliorated unexplained physical complaints of patients seen in primary care and offers an alternative for managing these common and problematic complaints in primary care settings.

Group therapy as treatment for depressed Latino women: a review of the literature

Group therapy has been recommended as a treatment for depression among Latino women. Thus, the literature published between 1980 and 2004 was systematically reviewed to explore cultural and therapeutic factors relevant to group therapy for depressed Latino women. The specific aims were to: (1) determine the type of studies on this topic, (2) identify successful forms of group therapy for this population, (3) identify therapeutic factors to consider while dealing with this population in group therapy, and (4) explore guidelines for conducting culturally sensitive groups for this population. Cognitive behavioral group therapy is recommended, yet few experimental studies have explored culturally relevant variations of this treatment. Culturally relevant therapeutic factors were mentioned in all studies.

Psychosocial and pharmacological interventions for depressed adults in primary care: a critical review

Primary care settings are the principal context for treating clinical depression, with researchers beginning to explore the efficacy of psychosocial and pharmacological treatments for depression within this infrastructure. Feasibility and process variables also are being assessed, including issues of cost-effectiveness, viability of collaborative care models, predictors of treatment outcome, and effectiveness of treatment providers without specialized mental health training. The Agency for Health Care Policy and Research and American Psychiatric Association initially released guidelines for the treatment of depression in primary care [American Psychiatric Association, 1993. Practice Guidelines for major depressive disorder in adults. American Journal of Psychiatry, 150, 1-26., American Psychiatric Association, 2000. Practice Guideline for the treatment of patients with major depressive disorder (revision). American Journal of Psychiatry, 157, 1-45], however, a vast literature has accumulated over the past several years, calling for a systematic re-evaluation of the status of depression treatment in primary care. The present study provides a contemporary review of outcome data for psychosocial and pharmacological interventions in primary care and extends beyond AHCPR guidelines insofar as focusing on feasibility and process variables, including the training and proficiency of primary care treatment providers, cost-effectiveness of primary care interventions, and predictors of treatment response and relapse. Based on current guidelines, problem-solving therapy (PST-PC), interpersonal psychotherapy, and pharmacotherapy would be considered efficacious interventions for major depression, with cognitive-behavioral and cognitive therapy considered possibly efficacious. Psychotherapy and pharmacotherapy generally are of comparable efficacy, and both modalities are superior to usual care in treating depression. Methodological limitations and directions for future research are discussed.

Reliability and validity of the Japanese version of the World Health Organization-Five Well-Being Index in the context of detecting depression in diabetic patients

The present study had two aims. The first was to evaluate the reliability and the validity of the Japanese version of the World Health Organization (WHO)-Five Well-Being Index (WHO-5-J) as a brief well-being scale. The second was to examine the discriminatory validity of this test as a screening tool for current depressive episodes in diabetic patients. A sample of 129 diabetic patients completed the WHO-5-J. Of these, 65 were also interviewed by psychiatrists to assess whether they had any current depressive episodes according to DSM-IV. The internal consistency was evaluated using Cronbach's alpha, the Loevinger coefficient of homogeneity, and factor analysis. The external concurrent validity was evaluated by correlations with the external scales potentially related to subjective well-being. Discriminatory validity was evaluated using receiver operating characteristic (ROC) analysis. Cronbach's alpha and the Loevinger coefficient were estimated to be 0.89 and 0.65, respectively. A factor analysis identified only one factor. The WHO-5-J was significantly correlated with a number of major diabetic complications, depression, anxiety, and subjective quality of life. ROC analysis showed that the WHO-5-J can be used to detect a current depressive episode (area under curve: 0.92; 95% confidence interval: 0.85-0.98). A cut-off of <13 yielded the best sensitivity/specificity trade-off: sensitivity, 100%; specificity, 78%. The WHO-5-J was thus found to have a sufficient reliability and validity, indicating that it is a useful instrument for detecting current depressive episodes in diabetic patients.

Effectiveness and cost effectiveness of counselling in primary care

BACKGROUND

The prevalence of mental health and psychosocial problems in primary care is high. This review examines the clinical and cost-effectiveness of psychological therapies provided in primary care by counsellors.

OBJECTIVES

To assess the effectiveness and cost effectiveness of counselling in primary care by reviewing cost and outcome data in randomised controlled trials for patients with psychological and psychosocial problems considered suitable for counselling.

SEARCH STRATEGY

To update the review, the following electronic databases were searched on 25-10-2005: MEDLINE, EMBASE, PsycLIT, CINAHL, the Cochrane Controlled Trials register and the Cochrane Collaboration Depression, Anxiety and Neurosis (CCDAN) trials registers.

SELECTION CRITERIA

All controlled trials comparing counselling in primary care with other treatments for patients with psychological and psychosocial problems considered suitable for counselling. Trials completed before the end of June 2005 were included in the review.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised data extraction sheet. Trials were rated for quality using CCDAN criteria, to assess the extent to which their design and conduct were likely to have prevented systematic error. Continuous measures of outcome were combined using standardised mean differences. An overall effect size was calculated for each outcome with 95% confidence intervals (CI). Continuous data from different measuring instruments were transformed into a standard effect size by dividing mean values by standard deviations. Sensitivity analyses were undertaken to test the robustness of the results. Economic analyses were summarised in narrative form.

MAIN RESULTS

Eight trials were included in the review. The analysis found significantly greater clinical effectiveness in the counselling group compared with usual care in the short-term (standardised mean difference -0.28, 95% CI -0.43 to -0.13, n = 772, 6 trials) but not the long-term (standardised mean difference -0.09, 95% CI -0.27 to 0.10, n = 475, 4 trials). Levels of satisfaction with counselling were high. There was some evidence that the overall costs of counselling and usual care were similar.

AUTHORS' CONCLUSIONS

Counselling is associated with modest improvement in short-term outcome compared to usual care, but provides no additional advantages in the long-term. Patients are satisfied with counselling. Although some types of health care utilisation may be reduced, counselling does not seem to reduce overall healthcare costs.

What drives referral from primary care physicians to mental health specialists? A randomized trial using actors portraying depressive symptoms

BACKGROUND

Referral from primary care to the mental health specialty sector is important but poorly understood.

OBJECTIVE

Identify physician characteristics influencing mental health referral.

DESIGN

Randomized controlled trial using Standardized Patients (SPs).

SETTING

Offices of primary care physicians in 3 cities.

PARTICIPANTS

One hundred fifty-two family physicians and general internists recruited from 4 broad practice settings; 18 middle aged Caucasian female actors.

INTERVENTION

Two hundred and ninety-eight unannounced SP visits, with assignments constrained so physicians saw 1 SP with major depression and 1 with adjustment disorder.

MEASUREMENTS

Mental health referrals via SP written reports; physician and system characteristics through a self-administered physician questionnaire.

RESULTS

Among 298 SP visits, 107 (36%) resulted in mental health referral. Referrals were less likely among physicians with greater self-confidence in their ability to manage antidepressant therapy (adjusted odds ratio [AOR] 0.39, 95% confidence interval [CI] 0.17 to 0.86) and were more likely if physicians typically spent > or =10% of professional time on nonclinical activities (AOR 3.42, 95% CI 1.45 to 8.07), had personal life experience with psychotherapy for depression (AOR 2.74, 95% CI 1.15 to 6.52), or usually had access to mental health consultation within 2 weeks (AOR 2.94, 95% CI 1.26 to 6.92).

LIMITATION

The roles portrayed by SPs may not reflect the experience of a typical panel of primary care patients.

CONCLUSIONS

Controlling for patient and health system factors, physicians' therapeutic confidence and personal experience were important influences on mental health referral. Research is needed to determine if addressing these factors can facilitate more appropriate care.

Watchful waiting for minor depression in primary care: remission rates and predictors of improvement

OBJECTIVES

The objectives of this study were to determine remission rates and predictors of improvement for minor depression following a 1-month watchful waiting period in primary care and to describe the watchful waiting processes.

METHODS

Prior to randomization into a clinical trial for minor depression, 111 participants were entered into a 1-month watchful waiting period. Depression severity and predictors of improvement were measured at the start of watchful waiting. At the end of watchful waiting, remission rates were calculated and predictor variables were analyzed for their contribution toward predicting improvement.

RESULTS

Remission rates were low, ranging from 9% to 13%, depending on the measure. Avoidant coping style and frequency of engaging in active pleasant events at baseline accounted for the majority of change in depression. During watchful waiting, about one fifth of the sample (21%) had at least one contact with their physician and 27% reported using self-initiated treatments.

CONCLUSIONS

There is a low likelihood of spontaneous remission for treatment-seeking samples with minor depression in primary care. An avoidant coping style seriously interferes with remission, and engaging in regular active pleasant events confers an advantage. Feasible interventions for primary care that promote activity and decrease avoidant coping styles may improve outcomes. These findings may not generalize to community and non-treatment-seeking samples.

Idiopathic physical symptoms: a common manifestation of psychiatric disorders in primary care

Worldwide, patients with common mental disorders, such as depression and anxiety, have a tendency to present first to primary care exhibiting idiopathic physical symptoms. Typically, these symptoms consist of pain and other physical complaints that remain medically unexplained. While in the past, traditional psychopathology emphasized the relevance of somatic presentations for disorders, such as depression, in the last few decades, the "somatic component" has been neglected in the assessment and treatment of psychiatric patients. Medical specialties have come up with a variety of "fashionable" labels to characterize these patients and the new psychiatric nomenclatures, such as the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, attempt to classify these patients into a separate "somatoform disorders" category. These efforts fall short, and revisionists are asking altogether for the elimination of "somatoform disorders" from future nomenclatures. This review emphasizes the importance of idiopathic physical symptoms to the clinical phenomenology of many psychiatric disorders, offers suggestions to the diagnostic conundrum, and provides some hints for the proper assessment and management of patients with these common syndromes.

Mother-Infant Interaction, Life Events and Prenatal and Postpartum Depressive Symptoms Among Urban Minority Women in Primary Care

OBJECTIVES

Prenatal and postpartum depression are significant mental health problems that can have negative effects on mother-infant interactions. We examined the relationships among mother-infant interactions, depressive symptoms, life events, and breastfeeding of low-income urban African American and Hispanic women in primary care settings.

METHODS

Participants were 89 African American and Hispanic women who were part of a larger mental health intervention study conducted in community health centers. Questionnaire data on depression, as well as negative and positive life events, were collected during pregnancy and at three-months postpartum, while mother-infant interaction observations and breastfeeding practice were only collected at three-months postpartum.

RESULTS

The ratings of maternal behavior for 'depressed' mothers did not differ from 'nondepressed' mothers. Except for gaze aversion behavior, infants' behavior while interacting with their mothers did not differ by maternal depression level. Hierarchical regression analyses revealed that maternal positive life events positively predicted infant interactional summary ratings, while maternal negative life events were inversely associated with maternal interactional summary ratings.

CONCLUSIONS

To improve services in primary care, perinatal screenings for depression can help identify those women most at risk. When follow-up use of structured diagnostic instruments is not possible or cost-effective, clinician assessment of severity of depression will determine women with clinical levels of depression. Reducing negative life events is beyond the control of women or clinicians but cognitive interventions to help women focus on positive life events can reduce the deleterious effects of depression on mothers and their infants.

The relationship of depression treatment quality indicators to employee absenteeism

Although employers commonly review administrative database indicators to assess depression treatment quality, they do not know whether these indicators predict relevant outcomes like absenteeism. In 230 employed patients in five health plans, we tested how administrative database-derived indicators for antidepressant medication and psychotherapy provided during the first 6 months of a new depression treatment episode predicted patient-reported absenteeism change over 12 months. The medication indicator was not significantly associated with absenteeism change over 12 months (p = .64); however, the psychotherapy indicator was significantly associated with an average 26.1% improvement in absenteeism over 12 months (p < .05). If subsequent studies confirm the results we report, quality monitoring initiatives interested in employer-relevant indicators of depression treatment quality should examine administrative database indicators of psychotherapy.

Hispanic ethnicity, language, and depression: physician-patient communication and patient use of alternative treatments

OBJECTIVE

To examine the relationship between Hispanic ethnicity and language spoken with physician communication about depression and patient use of alternative treatments for depression.

METHOD

This is a secondary data analysis from a trial of depression screening conducted in four primary care clinics. Patients with Hispanic or non-Hispanic White ethnic backgrounds and those meeting DSM-III-R criteria for current major depression, minor depression, dysthymia as well as those that screened positive on a depression screening instrument (n = 141) are included in this analysis. We labeled those who screened positive for depression but did not meet DSM-IIIR criteria for a current depressive disorder as "distressed." Clinicians' use of counseling and patient use of alternative treatments were based on patient self-report.

RESULTS

Forty-two percent (n = 59) of the sample stated that their physician had either told them that they had depression, treated them for depression, or recommended that they seek help for depression. Over 40% of patients spent time talking with their physicians at their current visit about what was making them depressed and 34% received counseling about depression. Hispanic ethnicity and language were not significantly related to physician communication with patients about how to overcome depression. Thirty-six percent of patients reported talking with a minister or other religious person about feelings of depression or sadness. Seventeen percent of patients had used herbal remedies or non-prescription medications and 5% had seen a curandero for feelings of depression or sadness. Hispanic ethnicity and language were not significantly related to patient use of alternative treatments for depression.

CONCLUSIONS

Hispanic ethnicity and language were not significantly related to physician-patient communication about depression or patient use of alternative treatments for depression. Physicians should make sure to ask patients about all of the types of things they are doing to help overcome their depression.

Cost-effectiveness of enhancing primary care depression management on an ongoing basis

PURPOSE

Although potentially costly, enhancing primary care depression management on an ongoing basis results in substantial long-term treatment effectiveness. The purpose of this article is to compare the cost-effectiveness of this approach with that of usual care.

METHODS

The study was conducted in 12 community primary care practices randomized to enhanced or usual care after stratification by baseline practice patterns. Practices assigned to enhanced care encouraged depressed patients to engage in active treatment, using practice nurses to provide regularly scheduled care management during the course of 24 months. We analyze outcomes for 211 adults (73.4% of potential eligible patients) beginning a new treatment episode for major depression determined by previsit screening. Outcomes included blinded estimates of days free of depression impairment as well as health care costs for 2 years.

RESULTS

Enhanced care significantly increased the number of days free of depression impairment for 2 years when compared with usual care (647.6 days vs 588.2 days, P <.01). The incremental cost-effectiveness ratio for enhanced care ranged from 9,592 dollars to 14,306 dollars per quality-adjusted life-year (QALY). The number of incremental days free of depression impairment increased between the first year and the second year (23.0 vs 36.4, respectively, P <.001) while incremental health plan costs decreased significantly (568 dollars vs -12 dollars, P <.001).

CONCLUSIONS

Enhancing primary care depression management on an ongoing basis should be considered for adoption by policy and health plan leaders.

Adapting psychosocial intervention research to urban primary care environments: a case example

PURPOSE

We wanted to describe the unique issues encountered by our research team in testing an intervention to reduce perinatal depression in real-world community health centers.

METHOD

We used a case study of an experience in conducting a randomized controlled trial designed to test the effectiveness of a low-cost multimodal psychosocial intervention to reduce prenatal and postpartum depression. Low-income minority women (N = 187) with low-risk pregnancies were randomly assigned to the intervention or treatment as usual. Outcomes of interest were depressive symptoms and social support assessed at 3 months' postpartum.

RESULTS

Our intervention was not associated with changes in depressive symptoms or social support. Challenges in implementation were related to participant retention and intervention delivery. Turnover of student therapists affected continuity in participant-therapist relationships and created missed opportunities to deliver the intervention. The academic-community partnership that was formed also required more involvement of health center personnel to facilitate ownership at the site level, especially for fidelity monitoring. While attentive to cultural sensitivity, the project called for more collaboration with participants to define common goals and outcomes. Participatory research strategies could have anticipated barriers to uptake of the intervention and achieved a better match between outcomes desired by researchers and those of participants.

CONCLUSION

Several criteria for future research planning emerged: assessing what the population is willing and able to accept, considering what treatment providers can be expected to implement, assessing the setting's capacity to accommodate intervention research, and collecting and using emerging unanticipated data.

Clinical efficacy of computerised cognitive-behavioural therapy for anxiety and depression in primary care: randomised controlled trial

BACKGROUND

Preliminary results have demonstrated the clinical efficacy of computerised cognitive-behavioural therapy (CBT) in the treatment of anxiety and depression in primary care.

AIMS

To determine, in an expanded sample, the dependence of the efficacy of this therapy upon clinical and demographic variables.

METHOD

A sample of 274 patients with anxiety and/or depression were randomly allocated to receive, with or without medication, computerised CBT or treatment as usual, with follow-up assessment at 6 months.

RESULTS

The computerised therapy improved depression, negative attributional style, work and social adjustment, without interaction with drug treatment, duration of preexisting illness or severity of existing illness. For anxiety and positive attributional style, treatment interacted with severity such that computerised therapy did better than usual treatment for more disturbed patients. Computerised therapy also led to greater satisfaction with treatment.

CONCLUSIONS

Computer-delivered CBT is a widely applicable treatment for anxiety and/or depression in general practice.

Treatment patterns and outcomes of depressed medically ill and non-medically ill patients in community psychiatric practice

The prevalence of depression among the medically ill, the recognition of depression in general medical practice, and the association between depression and medical illness have all been a focus for research in recent years. Less is known about the process and outcomes of depression care in the medically ill compared with the non-medically ill, but some studies suggest that those with concomitant physical illness have poorer outcomes. In a study of community psychiatric practice, a sample of 53 patients with no medical comorbidity (NMI) was compared with 50 patients, categorized by higher (HMI) or lower (LMI) levels of physical comorbidity, approximately 5 months after beginning treatment for a current episode of major depression. No differences were found in treatments received or in mental health outcomes between the three groups. The HMI group showed greater impairment in social and occupational functioning at baseline and significantly greater improvement in these variables at follow-up. Since medical comorbidity does not appear to adversely affect treatment decisions or outcomes in community psychiatric practice, depressed, physically ill patients should be encouraged to seek treatment, regardless of their medical condition or level of disability.

Cost-effectiveness of a primary care depression intervention

OBJECTIVE

To determine the incremental cost-effectiveness of a quality improvement depression intervention (enhanced care) in primary care settings relative to usual care.

DESIGN

Following stratification, we randomized 12 primary care practices to enhanced or usual care conditions and followed patients for 12 months.

SETTING

Primary care practices located in 10 states across the United States.

PATIENTS/PARTICIPANTS

Two hundred eleven patients beginning a new treatment episode for major depression.

INTERVENTIONS

Training the primary care team to assess, educate, and monitor depressed patients during the acute and continuation stages of their depression treatment episode over 1 year.

MEASUREMENTS AND MAIN RESULTS

Cost-effectiveness was measured by calculating incremental (enhanced minus usual care) costs and quality-adjusted life years (QALYs) derived from SF-36 data. The mean incremental cost-effectiveness ratio in the main analysis was US dollars 15463 per QALY. The mean incremental cost-effectiveness ratios for the sensitivity analyses ranged from US dollars 11341 (using geographic block variables to control for pre-intervention service utilization) to US dollars 19976 (increasing the cost estimates by 50%) per QALY.

CONCLUSIONS

This quality improvement depression intervention was cost-effective relative to usual care compared to cost-effectiveness ratios for common primary care interventions and commonly cited cost-effectiveness ratio thresholds for intervention implementation.

Clinical algorithms as a tool for psychotherapy with Latino clients

Clinical algorithms have the advantage of being able to integrate clinical, cultural, and environmental factors into a unified method of planning and implementing treatment. A model for practice is proposed that uses 3 algorithms as guides for conducting psychotherapy with Latino clients, the uses of which are illustrated in a single, ongoing case vignette. The algorithm format has the additional advantage of easily adapting itself for data gathering for research purposes.

Managing depression as a chronic disease: a randomised trial of ongoing treatment in primary care

OBJECTIVES

To evaluate the long term effect of ongoing intervention to improve treatment of depression in primary care.

DESIGN

Randomised controlled trial.

SETTING

Twelve primary care practices across the United States.

PARTICIPANTS

211 adults beginning a new treatment episode for major depression; 94% of patients assigned to ongoing intervention participated.

INTERVENTION

Practices assigned to ongoing intervention encouraged participating patients to engage in active treatment, using practice nurses to provide care management over 24 months.

MAIN OUTCOME MEASURES

Patients' report of remission and functioning.

RESULTS

Ongoing intervention significantly improved both symptoms and functioning at 24 months, increasing remission by 33 percentage points (95% confidence interval 7% to 46%), improving emotional functioning by 24 points (11 to 38) and physical functioning by 17 points (6 to 28). By 24 months, 74% of patients in enhanced care reported remission, with emotional functioning exceeding 90% of population norms and physical functioning approaching 75% of population norms.

CONCLUSIONS

Ongoing intervention increased remission rates and improved indicators of emotional and physical functioning. Studies are needed to compare the cost effectiveness of ongoing depression management with other chronic disease treatment routinely undertaken by primary care.

The effectiveness of psychotherapy in treating depressive disorders in primary care practice: clinical and cost perspectives

This paper reviews the clinical and cost effectiveness of psychotherapy for treating major and minor depression in primary care practice. Conclusions drawn from psychotherapy studies completed prior to 1995 were constrained by methodological deficiencies such as ambiguity regarding patient diagnostic status, use of non-specific psychotherapies, and lack of treatment manuals. More recent studies have addressed these flaws by shifting from efficacy to effectiveness designs, using standard diagnostic assessment procedures and appropriate follow-up time periods, using empirically evaluated treatment manuals, and selecting appropriate comparison conditions. Twelve primary care studies meeting these design criteria were analyzed, and the following conclusions were drawn: When used to treat major depression, a depression-specific psychotherapy produces better clinical outcomes than a primary care physician's usual care and outcomes similar to those produced by pharmacotherapy. When used to treat minor depression or dysthymia, the effectiveness of psychotherapy in comparison to usual care remains more equivocal. A review of the sparse data on cost effectiveness suggests that while psychotherapy has a higher fiscal cost than a physician's usual care, psychotherapy's higher value in treating patients with major depression may justify its use.

Rational treatment choices for non-major depressions in primary care: an evidence-based review

OBJECTIVE

This review synthesizes available evidence for managing clinically significant dysphoric symptoms encountered in primary care, when formal criteria for major depression or dysthymia are not met. Discussion is focused on premenstrual dysphoric disorder (PMDD) and minor depression because of their significant prevalence in the primary care setting and the lack of clear practice guidelines for addressing each illness.

DESIGN

English language literature from prior systematic reviews was supplemented by searching medline, embase, the Cochrane Controlled Trials Registry, the Agency for Healthcare Research and Quality National Guideline Clearinghouse, and bibliographies of selected papers. Studies addressing the natural history or treatment of minor depression or PMDD were selected for review. Data were abstracted by 1 of 2 independent reviewers and studies were synthesized qualitatively.

RESULTS

Five individual studies that compared antidepressant or psychological treatments to placebo in patients with minor depression suggest short-term improvements in depressive symptoms with paroxetine, problem-solving therapy, and cognitive behavioral therapy, but not with amitryptiline. Modest benefits on mental health function were reported with paroxetine and with problem-solving therapy, but only in patients with severe functional impairment at baseline. Twenty-four controlled trials were identified that compared antidepressant or psychological treatments to placebo in patients with premenstrual dysphoric disorder. Pooled results from a recent systematic review of 15 randomized controlled trials and one additional trial abstract provide strong evidence for a significantly greater improvement in physical and psychological symptoms with serotonin-selective reuptake inhibitor medications when compared with placebo. Individual trials also suggest significantly greater improvements in symptom scores with venlafaxine, but not with tricyclic antidepressants.

CONCLUSIONS

The limited evidence base for minor depression provides only mixed support for a small to moderate benefit for few antidepressant medications and psychological treatments tested. For the treatment of severe psychological or physical symptoms causing functional impairment in patients with PMDD, sertraline and fluoxetine are clearly beneficial in carefully selected patients.

Depression and negative life events among pregnant African-American and Hispanic women

Depression, social support, and life events were assessed in a sample of African-American and Hispanic women (N = 148) with uncomplicated pregnancies. Over half (51%) showed elevated depressive symptoms. Overall, women had fewer social supports and more negative life events than found in previous studies. African-Americans had more practical social support and persons in their support networks than Hispanics. Over a third of the sample (37%) had lost an important person in the past year. Depressed women reported more negative events than nondepressed women. Many negative life events and few social supports place minority women at risk for prenatal depression.

Effectiveness and cost effectiveness of counselling in primary care

BACKGROUND

Counsellors are prevalent in primary care settings. However, there are concerns about the clinical and cost-effectiveness of the treatments they provide, compared with alternatives such as usual care from the general practitioner, medication or other psychological therapies.

OBJECTIVES

To assess the effectiveness and cost effectiveness of counselling in primary care by reviewing cost and outcome data in randomised controlled trials, controlled clinical trials and controlled patient preference trials of counselling interventions in primary care, for patients with psychological and psychosocial problems considered suitable for counselling.

SEARCH STRATEGY

The original search strategy included electronic searching of databases (including the CCDAN Register of RCTs and CCTs) along with handsearching of a specialist journal. Published and unpublished sources (clinical trials, books, dissertations, agency reports etc.) were searched, and their reference lists scanned to uncover further controlled trials. Contact was made with subject experts and CCDAN members in order to uncover further trials. For the updated review, searches were restricted to those databases judged to be high yield in the first version of the review: MEDLINE, EMBASE, PSYCLIT and CINAHL, the Cochrane Controlled Trials register and the CCDAN trials register.

SELECTION CRITERIA

All controlled trials comparing counselling in primary care with other treatments for patients with psychological and psychosocial problems considered suitable for counselling. Trials completed before the end of June 2001 were included in the review.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised data extraction sheet. The relevant data were entered into the Review Manager software. Trials were quality rated, using CCDAN criteria, to assess the extent to which their design and conduct were likely to have prevented systematic error. Continuous measures of outcome were combined using standardised mean differences. An overall effect size was calculated for each outcome with 95% confidence intervals. Continuous data from different measuring instruments were transformed into a standard effect size by dividing mean values by standard deviations. In view of the diversity of counselling services in primary care (the range of treatments, patients and practitioners) tests of heterogeneity were done to assess the feasibility of aggregating measures of outcome from trials. Sensitivity analyses were undertaken to test the robustness of the results.

MAIN RESULTS

Seven trials were included in the review. The main analyses showed significantly greater clinical effectiveness in the counselling group compared with 'usual care' in the short-term (standardised mean difference -0.28, 95% CI -0.43 to -0.13, n=772, 6 trials) but not the long-term (standardised mean difference -0.09, 95% CI -0.27 to 0.10, n=475, 4 trials). Levels of satisfaction with counselling were high. Four studies reported similar total costs associated with counselling and usual care over the long-term. However, the economic analyses were likely to be underpowered.

REVIEWER'S CONCLUSIONS

Counselling is associated with modest improvement in short-term outcome compared to 'usual care', but provides no additional advantages in the long-term. Patients are satisfied with counselling, and it may not be associated with increased costs.

Status of minor depression or dysthymia in primary care following a randomized controlled treatment

This report describes the rates of recovery and remission from minor depression or dysthymia in primary care patients three months after completing a randomized controlled treatment trial. The subjects were primary care patients who received > or =4 treatment sessions with Problem-Solving Treatment, paroxetine, or placebo and who completed an independent assessment 3 months after the study (201 with minor depression, 229 with dysthymia). The 17-item Hamilton Rating Scale for Depression (HAMD), semistructured questions about postintervention depression treatments, and baseline medical comorbidity, neuroticism, and social function were the primary measures. For minor depression 76% and for dysthymia 68% of subjects who were in remission at the end of the 11-week treatment trial were recovered (HAMD < or =6) three months after the treatment trial. Of patients who were not in remission at 11 weeks, for minor depression 37% and for dysthymia 31% went on to achieve remission at 25 weeks. The majority of patients chose not to use antidepressants or psychotherapy after the trial. Patients with minor depression that had greater baseline social function and lower neuroticism scores were more likely to be recovered. For patients with minor depression, these findings suggest a need for some matching of continuation and maintenance treatment to patient characteristics rather than uniform, automatic treatment recommendations. Because of the chronic, relapsing nature of dysthymia, practical improvements in encouraging effective continuation and maintenance phases of treatment are indicated.

The Quality Improvement for Depression collaboration: general analytic strategies for a coordinated study of quality improvement in depression care

It is difficult to evaluate the promise of primary care quality-improvement interventions for depression because published studies have evaluated diverse interventions by using different research designs in dissimilar populations. Preplanned meta-analysis provides an alternative to derive more precise and generalizable estimates of intervention effects; however, this approach requires the resolution of analytic challenges resulting from design differences that threaten internal and external validity. This paper describes the four-project Quality Improvement for Depression (QID) collaboration specifically designed for preplanned meta-analysis of intervention effects on outcomes. This paper summarizes the interventions the four projects tested, characterizes commonalities and heterogeneity in the research designs used to evaluate these interventions, and discusses the implications of this heterogeneity for preplanned meta-analysis.

The prevalence of comorbid depression in adults with diabetes: a meta-analysis

OBJECTIVE

To estimate the odds and prevalence of clinically relevant depression in adults with type 1 or type 2 diabetes. Depression is associated with hyperglycemia and an increased risk for diabetic complications; relief of depression is associated with improved glycemic control. A more accurate estimate of depression prevalence than what is currently available is needed to gauge the potential impact of depression management in diabetes.

RESEARCH DESIGN AND METHODS

MEDLINE and PsycINFO databases and published references were used to identify studies that reported the prevalence of depression in diabetes. Prevalence was calculated as an aggregate mean weighted by the combined number of subjects in the included studies. We used chi(2) statistics and odds ratios (ORs) to assess the rate and likelihood of depression as a function of type of diabetes, sex, subject source, depression assessment method, and study design.

RESULTS

A total of 42 eligible studies were identified; 20 (48%) included a nondiabetic comparison group. In the controlled studies, the odds of depression in the diabetic group were twice that of the nondiabetic comparison group (OR = 2.0, 95% CI 1.8-2.2) and did not differ by sex, type of diabetes, subject source, or assessment method. The prevalence of comorbid depression was significantly higher in diabetic women (28%) than in diabetic men (18%), in uncontrolled (30%) than in controlled studies (21%), in clinical (32%) than in community (20%) samples, and when assessed by self-report questionnaires (31%) than by standardized diagnostic interviews (11%).

CONCLUSIONS

The presence of diabetes doubles the odds of comorbid depression. Prevalence estimates are affected by several clinical and methodological variables that do not affect the stability of the ORs.
