Targeted prevention of unipolar depressive disorder in an at-risk sample of high school adolescents: a randomized trial of a group cognitive intervention

Adolescent Primary Care Patients’ Preferences for Depression Treatment

Despite efficacious treatments for depression in youth, current data indicate low rates of care. To better understand reasons for these low rates of care, we examined treatment preferences for depression treatment. Adolescents (N=444) who screened positive for depression at a primary care visit completed measures of predisposing, enabling, and need characteristics thought to be related to help seeking. Results indicated a strong tendency for adolescents to prefer active treatment (72%) versus watchful waiting (28%), and for youth to prefer counseling (50%) versus medication (22%). Female gender, prior treatment experience, and current depression and anxiety were related to preference for active treatment over watchful waiting. In multivariable analyses, female gender and current anxiety symptoms remained significant predictors of preference for active treatment. Ethnicity, attitudes about depression care, prior treatment experience, and anxiety symptoms were related to preference for medication over counseling. In multivariable analyses, those with negative attitudes about depression treatment generally, with positive attitudes about treatment via medication, or with current anxiety symptoms were more likely to prefer medication. Youth preference for counseling over medication may contribute to low adherence to medication treatment and underscores the importance of patient education aimed at promoting positive expectations for treatments.

Depression Prevention for Early Adolescent Girls: A Pilot Study of All Girls Versus Co-Ed Groups

Given the dramatic increase in depression that occurs during early adolescence in girls, interventions must address the needs of girls. The authors examined whether a depression prevention program, the Penn Resiliency Program, was more effective for girls in all-girls groups than in co-ed groups. Within co-ed groups, the authors also tested whether there were greater effects for boys than for girls. Participants were 208 11- to 14-year-olds. Girls were randomly assigned to all-girls groups, co-ed groups, or control. Boys were assigned to co-ed groups or control. Students completed questionnaires on depressive symptoms, hopelessness, and explanatory style before and after the intervention. Girls groups were better than co-ed groups in reducing girls'hopelessness and for session attendance rates but were similar to co-ed groups in reducing depressive symptoms. Co-ed groups decreased depressive symptoms, but this did not differ by gender. Findings support prevention programs and suggest additional benefits of girls groups.

Possibilities for intervention in adolescents' and young adults' depression from a public health perspective

When considering measures to decrease the burden of disease that is caused by depression, depressive disorders of adolescents and young adults are of increasing interest. The prevalence of depressive disorders in adolescents and young adults is high. The probable increases in prevalence affect predominantly young people and their prognosis is particularly bad. This review discusses the potentials to influence the burden of disease through interventions such as therapy, including measures to detect persons at risk early, selective and universal prevention, and health promotion for adolescents and young adults. It considers the available evidence for the effectiveness of these interventions on the public health level. In addition, the suitability of implementation and ethical considerations are discussed. As a conclusion, health policy in its aim to reduce the burden of depressive disease should focus on increasing treatment rates and improving the efficiency of treatment in adolescents and young adults as well for depression as for other mental disease that has high co-morbidity with depression. In addition, the focus should be set on indicated prevention for children of depressed parents and--for health promotion reasons--on policies that impact on living-conditions of families.

Promoting and protecting youth mental health through evidence-based prevention and treatment

For decades, empirically tested youth interventions have prevented dysfunction by addressing risk and ameliorated dysfunction through treatment. The authors propose linking prevention and treatment within an integrated model. The model suggests a research agenda: Identify effective programs for a broadened array of problems and disorders, examine ethnicity and culture in relation to intervention adoption and impact, clarify conditions under which programs do and do not work, identify change mechanisms that account for effects, test interventions in real-world contexts, and make tested interventions accessible and effective in community and practice settings. Connecting the science and practice of prevention and treatment will be good for science, for practice, and for children, adolescents, and their families.

Continuation and maintenance therapy of early-onset major depressive disorder

Child and adolescent depression is a serious and often episodic disorder with a high rate of recurrence equal to or surpassing that of adult depression. Symptoms of depression are similar in child, adolescent, and adult populations. The diagnostic criteria are the same, with the possible exception that children and adolescents are more likely to present with irritability without clear sadness. Despite the similarities between adult, adolescent, and child depression, results of studies of psychosocial and pharmacologic treatments in adult depression are not necessarily applicable to the pediatric population. The treatment of depression has been divided into three phases: acute (leading to clinical response and remission of symptoms); continuation (prevention of symptom relapse); and maintenance (prevention of new episodes or recurrences). According to research of acute treatment of child and adolescent depression with pharmacotherapy, selective serotonin reuptake inhibitors (SSRIs) are considered the first-line treatment. Recent controversies have caused some concern about the use of SSRIs in children and adolescents; however, SSRIs remain the initial pharmacologic treatment of choice. Acute treatment with non-specific psychotherapy is considered an essential component in the management of depression, but has not been shown to be equally effective as pharmacotherapy or specific psychotherapies by itself. There is increasing evidence that cognitive behavior therapy and interpersonal therapy are effective for the treatment of early-onset depression. Unfortunately, severe depression, comorbid diagnoses, family discord, and increased impairment may hinder the establishment of remission; these factors have been associated with treatment resistance. Once remission of depressive symptoms is established, continuation and maintenance treatment should be considered. Only one study of continuation treatment has been completed in child and adolescent depression; the results support the use of fluoxetine as a safe and effective treatment for reducing relapse. To date, no studies have been reported on maintenance treatment with specific therapies in child and adolescent depression, but trials in adults have demonstrated the importance of continued pharmacotherapy beyond the continuation phase of the illness. Although several factors are associated with response to treatment in children and adolescents with depression, including younger age, lower severity of depressive symptoms, higher family functioning, and fewer comorbid diagnoses, few studies have consistently demonstrated predictors of relapse and recurrence.

Effects of psychotherapy for depression in children and adolescents: a meta-analysis

Serious sequelae of youth depression, plus recent concerns over medication safety, prompt growing interest in the effects of youth psychotherapy. In previous meta-analyses, effect sizes (ESs) have averaged .99, well above conventional standards for a large effect and well above mean ES for other conditions. The authors applied rigorous analytic methods to the largest study sample to date and found a mean ES of .34, not superior but significantly inferior to mean ES for other conditions. Cognitive treatments (e.g., cognitive-behavioral therapy) fared no better than noncognitive approaches. Effects showed both generality (anxiety was reduced) and specificity (externalizing problems were not), plus short- but not long-term holding power. Youth depression treatments appear to produce effects that are significant but modest in their strength, breadth, and durability.

The prevention of depressive symptoms in children and adolescents: A meta-analytic review

Research on the prevention of depressive symptoms in children and adolescents was reviewed and synthesized with meta-analysis. When all 30 studies were included, selective prevention programs were found to be more effective than universal programs immediately following intervention. Both selective and indicated prevention programs were more effective than universal programs at follow-up, even when the 2 studies with college students were excluded. Effect sizes for selective and indicated prevention programs tended to be small to moderate, both immediately postintervention and at an average follow-up of 6 months. Most effective interventions are more accurately described as treatment rather than prevention. Suggestions for future research include testing potential moderators (e.g., age, gender, anxiety, parental depression) and mechanisms, designing programs that are developmentally appropriate and gender and culturally sensitive, including longer follow-ups, and using multiple measures and methods to assess both symptoms and diagnoses.

General psychiatrists and their patients' children: assessment and prevention

General psychiatrists frequently treat adult patients with Major Depressive Disorder. Ordinarily, these psychiatrists focus solely on the treatment of their adult patients. However, new data suggest that treatment efforts might be doubly rewarded if psychiatrists tended to the children of these patients as well. This article reviews the literature on children whose parents have Major Depressive Disorder, and on preventive interventions for their children. We also review challenges to funding interventions of this sort based on systematic interviews of public and private insurance providers. We suggest a new standard of care for depressed patients: reliable screening of the patients' children for both risk of disorder and resilience as well as referral of these children, where indicated, for prevention services. We review obstacles to this standard of care: the professional reluctance of general psychiatrists to work with children and the lack of screening and preventive services for these children in most practice settings.

Depression and role impairment among adolescents in primary care clinics

PURPOSE

To evaluate the association between depression and role impairment in a primary care sample, with and without controlling for the effects of general medical conditions.

METHODS

Cross-sectional survey of consecutive primary care patients, ages 13-21 years (n = 3471), drawn from six sites including public health, managed care, and academic health center clinics. We assessed probable depressive disorder, depressive symptoms, and common medical problems using youth self-report on a brief screening questionnaire. Main outcome measures were two indicators of role impairment: (a) decrement in productivity/role activity, defined as not in school or working full time; and (b) low educational attainment, defined as more than 2 years behind in school or > or = 20 years of age and failed to complete high school.

RESULTS

Adolescents screening positive for probable depressive disorder had elevated rates of productivity/role activity decrements (19% vs. 13%; OR 1.69; 95% confidence interval [CI] 1.39-2.06; p < 0.001) and low educational attainment (20% vs. 15%; OR 1.47; 95% CI 1.21-1.78; p < 0.001). Probable depressive disorder made a unique contribution to the prediction of these impairment indicators after adjusting for the effect of having a general medical condition; controlling for depression, the presence of a general medical condition did not contribute to role impairment.

CONCLUSIONS

Adolescent primary care patients screening positive for depression are at increased risk for impairment in school/work productivity and educational attainment. These findings emphasize the importance of primary care clinicians' attention to depression and role limitations.

Practice parameter for psychiatric consultation to schools

This practice parameter reviews the topic of psychiatric consultation to schools. The review covers the history of school consultation and current consultative models; the process of developing a consultative relationship; school administrative procedures, personnel, and milieu; legal protections for students with mental disabilities; and issues typically arising in consultative situations. The objective of the parameter is to provide an introduction to the special vocabulary, knowledge, and skills that are important prerequisites for successful consultation in school settings.

Depressive Symptoms in Adolescents Living in Rural America

PURPOSE

The purposes of this pilot study were to examine prevalence of depressive symptoms among rural adolescents and identify related social and environmental variables.

METHODS

A convenience sample of 299 14- to 18-year-old agriculture class students at 5 rural high schools in Kentucky and Iowa completed a survey that included demographic information, family farm history, experience with suicide, perception of school environment, and indicators of farm injuries and risky behaviors. Participants also completed the Center for Epidemiologic Studies Depression Scale (CES-D) as well as scales to assess the number of major life events in the last year, active coping use, and family closeness.

FINDINGS

The prevalence of a high level of depressive symptoms (CES-D > or = 16) in this sample was 34%. Nine percent had seriously considered suicide in the last year. Unlike previous reports, boys reported as many depressive symptoms as girls. Although the literature reports that engaging in risky behavior is associated with depressive symptoms, the only risky behavior linked with depressive symptoms in this sample was operating a 4-wheel all-terrain vehicle. Other predictors of depressive symptoms included poor family relationships and poor active coping.

CONCLUSIONS

Interventions to identify and prevent depressive symptoms in rural adolescents are needed. Boosting active coping and improving family function may also prevent the development of clinical depression in rural adolescents.

Overcoming Depression on the Internet (ODIN) (2): a randomized trial of a self-help depression skills program with reminders

Background

Guided self-help programs for depression (with associated therapist contact) have been successfully delivered over the Internet. However, previous trials of pure self-help Internet programs for depression (without therapist contact), including an earlier trial conducted by us, have failed to yield positive results. We hypothesized that methods to increase participant usage of the intervention, such as postcard or telephone reminders, might result in significant effects on depression.

Objectives

This paper presents a second randomized trial of a pure self-help Internet site, ODIN (Overcoming Depression on the InterNet), for adults with self-reported depression. We hypothesized that frequently reminded participants receiving the Internet program would report greater reduction in depression symptoms and greater improvements in mental and physical health functioning than a comparison group with usual treatment and no access to ODIN.

Methods

This was a three-arm randomized control trial with a usual treatment control group and two ODIN intervention groups receiving reminders through postcards or brief telephone calls. The setting was a nonprofit health maintenance organization (HMO). We mailed recruitment brochures by US post to two groups: adults (n = 6030) who received depression medication or psychotherapy in the previous 30 days, and an age- and gender-matched group of adults (n = 6021) who did not receive such services. At enrollment and at 5-, 10- and 16-weeks follow-up, participants were reminded by email (and telephone, if nonresponsive) to complete online versions of the Center for Epidemiological Studies Depression Scale (CES-D) and the Short Form 12 (SF-12). We also recorded participant HMO health care services utilization in the 12 months following study enrollment.

Results

Out of a recruitment pool of 12051 approached subjects, 255 persons accessed the Internet enrollment site, completed the online consent form, and were randomized to one of the three groups: (1) treatment as usual control group without access to the ODIN website (n = 100), (2) ODIN program group with postcard reminders (n = 75), and (3) ODIN program group with telephone reminders (n = 80). Across all groups, follow-up completion rates were 64% (n = 164) at 5 weeks, 68% (n = 173) at 10 weeks, and 66% (n = 169) at 16 weeks. In an intention-to-treat analysis, intervention participants reported greater reductions in depression compared to the control group (P = .03; effect size = 0.277 standard deviation units). A more pronounced effect was detected among participants who were more severely depressed at baseline (P = .02; effect size = 0.537 standard deviation units). By the end of the study, 20% more intervention participants moved from the disordered to normal range on the CES-D. We found no difference between the two intervention groups with different reminders in outcomes measures or in frequency of log-ons. We also found no significant intervention effects on the SF-12 or health care services.

Conclusions

In contrast to our earlier trial, in which participants were not reminded to use ODIN, in this trial we found a positive effect of the ODIN intervention compared to the control group. Future studies should address limitations of this trial, including relatively low enrollment and follow-up completion rates, and a restricted number of outcome measures. However, the low incremental costs of delivering this Internet program makes it feasible to offer this type of program to large populations with widespread Internet access.

Long-term outcome of a school-based, universal approach to prevention of depression in adolescents

In this study, the authors examined the 2-, 3-, and 4-year outcomes of a school-based, universal approach to the prevention of adolescent depression. Despite initial short-term positive effects, these benefits were not maintained over time. Adolescents who completed the teacher-administered cognitive-behavioral intervention did not differ significantly from adolescents in the monitoring-control condition in terms of changes in depressive symptoms, problem solving, attributional style, or other indicators of psychopathology from preintervention to 4-year follow-up. Results were equivalent irrespective of initial level of depressive symptoms.

Standards of Evidence: Criteria for Efficacy, Effectiveness and Dissemination

Ever increasing demands for accountability, together with the proliferation of lists of evidence-based prevention programs and policies, led the Society for Prevention Research to charge a committee with establishing standards for identifying effective prevention programs and policies. Recognizing that interventions that are effective and ready for dissemination are a subset of effective programs and policies, and that effective programs and policies are a subset of efficacious interventions, SPR's Standards Committee developed overlapping sets of standards. We designed these Standards to assist practitioners, policy makers, and administrators to determine which interventions are efficacious, which are effective, and which are ready for dissemination. Under these Standards, an efficacious intervention will have been tested in at least two rigorous trials that (1) involved defined samples from defined populations, (2) used psychometrically sound measures and data collection procedures; (3) analyzed their data with rigorous statistical approaches; (4) showed consistent positive effects (without serious iatrogenic effects); and (5) reported at least one significant long-term follow-up. An effective intervention under these Standards will not only meet all standards for efficacious interventions, but also will have (1) manuals, appropriate training, and technical support available to allow third parties to adopt and implement the intervention; (2) been evaluated under real-world conditions in studies that included sound measurement of the level of implementation and engagement of the target audience (in both the intervention and control conditions); (3) indicated the practical importance of intervention outcome effects; and (4) clearly demonstrated to whom intervention findings can be generalized. An intervention recognized as ready for broad dissemination under these Standards will not only meet all standards for efficacious and effective interventions, but will also provide (1) evidence of the ability to "go to scale"; (2) clear cost information; and (3) monitoring and evaluation tools so that adopting agencies can monitor or evaluate how well the intervention works in their settings. Finally, the Standards Committee identified possible standards desirable for current and future areas of prevention science as the field develops. If successful, these Standards will inform efforts in the field to find prevention programs and policies that are of proven efficacy, effectiveness, or readiness for adoption and will guide prevention scientists as they seek to discover, research, and bring to the field new prevention programs and policies.

Prevention of schizophrenia: can it be achieved?

Schizophrenia is a serious mental disorder with a profound impact on patients, their caregivers and society. It is also an expensive disorder to treat, despite being relatively rare. In this paper, prevention of schizophrenia is described in terms of primary, secondary and tertiary prevention. Schizophrenia is regarded as a neurodevelopmental disorder with different phases. Primary prevention essentially involves education programmes about the association of obstetric complications and the increased risk of schizophrenia. Secondary prevention involves intervention at the prodromal phase. We review the literature and discuss the evidence relating to intervention in this phase of the illness. Early intervention could result in reduction in morbidity and better quality of life for the patients and their families. The prodromal phase can now be identified, based on current symptoms, with reliability and predictive validity for the risk of development of schizophrenia in the following year. We also discuss possible risks faced by prodromal patients, such as unnecessary stigmatisation, and the role of drug treatment during intervention at this stage. Any recommendation that anti-psychotic medications be routinely prescribed in this phase should be supported by more research work. Drug and psychosocial intervention is indicated as part of tertiary prevention to prevent further disability in the illness.

Adolescents coping with mom's breast cancer: developing family intervention programs

The purpose of this pilot study was to gain a deeper understanding of how adolescents are affected by their mothers' breast cancer and to discover their opinions about how future intervention programs should be designed. Three focus groups were conducted with a total of 10 adolescents. Findings indicate that adolescents' lives had been complicated by their mothers' illness, as they often felt burdened with additional roles and responsibilities. Adolescents suggested that future intervention programs should have the following elements: Adolescent group comprised of boys and girls within 4 months of cancer diagnosis; psychoeducation; target coping skills sensitive to girls and boys of different ethnic and racial backgrounds; and after the adolescent groups, have multiple-family therapy groups that promote shared family understanding and open communication between parents and adolescents.

Adapting and disseminating effective public health interventions in another country: towards a systematic approach

BACKGROUND

Public health interventions that have proven effective in one country, are often adapted and disseminated in other countries. However, the process by which effective interventions are chosen for adaptation and dissemination in another country is often not conducted systematically.

METHODS

We propose a more systematic approach and describe the main steps that have to be taken in the assessment of the usefulness of effective interventions in another national context.

RESULTS

The following steps are proposed. Step 0: Point out the most relevant areas in public health (this is a collaborative effort by policy makers, scientists and practitioners). Step 1: Identification of potentially effective interventions (through systematic literature searches). Step 2: Assessing the levels of evidence and grades of recommendation for adoption. Step 3: Can the results of the trials be generalized to the national situation? Step 4: Can the intervention be implemented in the national situation?

CONCLUSION

A more systematic approach to the adaptation and dissemination can be adopted. The basic steps described should be worked out in more detail before they can be used in practice.

Preventing the incidence of new cases of mental disorders: a meta-analytic review

To assess the results of studies examining the effects of preventive interventions on the incidence of mental disorders, we conducted a systematic review. A literature search resulted in 13 high-quality randomized trials, six on depressive disorder (including postpartum depression), one on anxiety, one examining both anxiety and depression, three on posttraumatic stress disorders, one on psychosis, and one on any mental disorder. The overall relative risk (RR) was 0.73 (95% CI, 0.56-0.95), indicating a reduction of the risk to become a new case of a mental disorder. The seven studies on prevention of depressive disorder resulted in a RR of 0.72 (95% CI, 0.54-0.96). The risk of posttraumatic stress disorder was somewhat increased after debriefing, but not significantly (RR=1.33), indicating a possible adverse effect. Prevention of new cases of mental disorders seems to be possible and may be an important way of reducing the enormous burden of these disorders.

Predicting the onset of major depression in subjects with subthreshold depression in primary care: a prospective study

OBJECTIVE

That subjects with subthreshold depression have an increased probability of developing major depression has been confirmed by many studies. However, the factors which may predict the onset of major depression have yet to be fully examined.

METHOD

We examined the control group of a randomized trial in primary care patients with subthreshold depression (N = 109), of whom 20 had developed major depression 1 year later. Using the vulnerability-stress theory, we examined which factors predicted the onset of major depression.

RESULTS

In both univariate and multivariate analyses, family history and chronic illnesses predicted the onset of major depression.

CONCLUSION

It is possible to predict to a certain degree whether a subject with subthreshold depression will develop major depression within a year.

Minimal-contact psychotherapy for sub-threshold depression in primary care. Randomised trial

BACKGROUND

Sub-threshold depression is a prognostic variable for major depression. Interventions in sub-threshold depression may prevent the onset of new cases of major depression.

AIMS

To examine the effects of minimal-contact psychotherapy in primary care patients with sub-threshold depression on the onset of major depression, on the reduction in depressive symptoms and on health-related quality of life.

METHOD

We conducted a randomised trial in primary care, in which patients screened for sub-threshold depression were randomly assigned to minimal-contact psychotherapy (n=107) or to usual care (n=109).

RESULTS

One year after baseline, the incidence of major depressive disorder was found to be significantly lower in the psychotherapy group (12%) than in those receiving usual care (18%). Small but significant effects were also found on depressive symptoms and on aspects of health-related quality of life.

CONCLUSIONS

Primary care patients with sub-threshold depression can benefit from minimal-contact psychotherapy.

Empirically tested psychotherapies for youth internalizing and externalizing problems and disorders

This article is a review of specific psychotherapies that have been supported in clinical trials. Treatments that showed significant effects in studies published over a period of 4 decades were identified, with the goal of complementing the overall picture of treatment benefit provided in narrative reviews and meta-analyses with a detailing of the specific interventions that have shown significant effects. The article focuses on treatments for four broad clusters of problems and disorders that account for a very large proportion of youth mental health referrals: anxiety, depression, attention-deficit/hyperactivity, and conduct.

Pharmacological treatment of adolescent major depression

Antidepressant agents are widely prescribed for adolescents, although specific data regarding their efficacy in this age range are limited. The aims of the present article are to review research findings regarding the use of antidepressant drugs for adolescent depression and to discuss the main results in light of our clinical experience. Only 13 controlled trials on the use of antidepressant drugs for adolescent major depression are available in the literature. Six studies evaluated the efficacy of tricyclic antidepressants, yet they only included 196 adolescents altogether. Seven studies, including a total of 1,403 patients, evaluated the efficacy of three specific serotonin reuptake inhibitors: fluoxetine, paroxetine, and sertraline. Based on published data, serotonin reuptake inhibitors appear to be the first-line psychopharmacologic treatment for adolescent depression, as three compounds (fluoxetine, paroxetine, and sertraline) appeared to be effective in this indication. Conversely, all published studies failed to demonstrate that the tricyclic antidepressants were superior to placebo. Several questions remain open and are discussed: How should we use available scientific data in clinical practice? Are there nonspecific factors implicated in treatment response? Is there a serotonin hypothesis for juvenile depression? What are the priorities for future research?

School-based prevention of depressive symptoms in adolescents: a 6-month follow-up

OBJECTIVE

Depressive disorders in adolescents are a widespread problem with extensive psychosocial consequences. The authors designed a school-based program to prevent the increase in depressive symptoms. The authors expect the program to reduce dysfunctional automatic thoughts and improve social skills and thus prevent the increase in depressive symptoms.

METHOD

The design includes a training group and a nontreatment control group with pre- and post-measurement and 3- and 6-month follow-up. The authors followed up 324 eighth graders in both groups. School classes were randomly assigned to one of the two groups. The prevention program, LISA-T, is based on cognitive-behavioral therapy concepts and targets of cognitive and social aspects. It comprises 10 meetings of 1.5 hours in a regular school setting.

RESULTS

Increases in depressive symptoms in nondepressed adolescents in the training group were prevented over a 6-month period. Furthermore, adolescents with subsyndromal depression in the training group reported fewer symptoms, whereas depressive symptoms within the control group did not change. However, the groups did not differ with regard to social skills, frequency of negative automatic thoughts, and depressive symptoms before the prevention program.

CONCLUSIONS

LISA-T is an effective school-based prevention program for eighth graders with minimal to mild depressive symptoms, but further research is needed.

A review of clinical characteristics and residential treatments for adolescent delinquents with mental health disorders: a promising residential program

As treatment systems throughout the country have deinstitutionalized, under-use of community-based residential treatment systems has escalated. Reliance on juvenile justice systems for the care of the mentally ill adolescent has increased. There is considerable overlap between the mentally ill adolescent population within the community-based mental health systems and the offender population within the juvenile justice systems. With the inconsistent epidemiological prevalence and longitudinal treatment data, mental health treatment providers have also begun addressing this problem. This is currently being done by designing and implementing community-based residential mental health programs for delinquent adolescents of the juvenile justice system as well as nondelinquent adolescents within the mental health treatment systems. Providers have relied on both systems' literature in establishing theoretical treatment programs. The authors review critical treatment components currently used by both the treatment and juvenile justice systems. A promising integrative program is described.

A randomized placebo-controlled trial of a school-based depression prevention program

OBJECTIVE

To conduct a placebo-controlled study of the effectiveness of a universal school-based depression prevention program.

METHOD

Three hundred ninety-two students age 13 to 15 from two schools were randomized to intervention (RAP-Kiwi) and placebo programs run by teachers. RAP-Kiwi was an 11-session manual-based program derived from cognitive-behavioral therapy. The placebo was similar but with cognitive components removed. Outcomes were self-rated depression scales, the Reynolds Adolescent Depression Scale (RADS), and the Beck Depression Inventory II (BDI-II). Follow-up was to 18 months. Analysis was done on an intent-to-treat basis.

RESULTS

Immediately after the intervention, depression scores were reduced significantly more by RAP-Kiwi than by placebo, with a mean difference in change from baseline between groups of 1.5 on BDI-II (CI > 0.38, p =.01) and 2.24 on RADS (CI > 0.22, p =.04). Categorical analysis confirmed significant clinical benefit with an absolute risk reduction of 3% (95% CI, 1-11%, McNemar chi, p =.03), with the "number needed to treat" for short-term benefit of 33. Group differences in depression scores averaged across time to 18 months were significant on RADS but not on BDI-II. Retention rates were 91% at 6 months and 72% at 18 months.

CONCLUSIONS

The RAP-Kiwi program is a potentially effective public health measure. Confirmation of effectiveness measuring episodes of depressive illness and broader measures of adjustment is warranted.

Subthreshold depression as a risk indicator for major depressive disorder: a systematic review of prospective studies

OBJECTIVE

In order to examine whether the incidence of major depressive disorder (MDD) is increased in subjects with subthreshold depression, or sD (clinically relevant depressive symptoms, without meeting criteria for a full-blown MDD), we conducted a review of prospective studies examining the incidence of MDD in subjects with sD.

METHOD

A systematic literature search was conducted. For all studies, the relative risk of developing MDD was calculated, based on person-years.

RESULTS

Twenty studies (23 comparisons) were found, based on community samples, general medical patients and high-risk subjects. Most comparisons showed that subjects with sD had a consistently larger chance of developing MDD. The studies differed considerably in the definition of sD, the recency (occurrence of the last sD) and the in-/exclusion of lifetime MDD.

CONCLUSION

The incidence of MDD in subjects with sD is larger than in subjects without sD. Otherwise, the concept of sD is too broad to be used. In future studies, some consensus should be reached regarding the definition of sD.

Leitlinien zur Diagnostik und Psychotherapie von depressiven Störungen im Kindes- und Jugendalter: Ein evidenzbasierter Diskussionsvorschlag

Zusammenfassung. Ein Entwurf evidenzbasierter Leitlinien zur Diagnostik und Psychotherapie von depressiven Störungen im Kindes- und Jugendalter wird vorgestellt. Für die Diagnosestellung depressiver Störungen im Kindes- und Jugendalter müssen die gleichen diagnostischen Kriterien nach ICD-10 erfüllt sein wie für Erwachsene. Allerdings kann das klinische Bild einer Depression in verschiedenen Altersgruppen deutlich variieren. Depressive Störungen sind vor allem im Jugendalter häufig, chronische Verläufe und Rückfälle treten auf und sie gehen oft mit komorbiden Störungen wie Angststörungen, Störungen des Sozialverhaltens und Störungen durch Substanzgebrauch einher. Wirksame Interventionsansätze zur Prävention depressiver Störungen und zur Akutbehandlung bei leichten und mittelschweren depressiven Störungen stehen zur Verfügung. Die psychotherapeutischen Interventionen der Wahl stellen derzeit kognitiv-verhaltenstherapeutische Ansätze (KVT) und die interpersonale Therapie (IPT) dar. Die Antidepressiva der Wahl sind derzeit selektive Serotoninwiederaufnahmehemmer (SSRI). Weitere Studien, vor allem hinsichtlich Rückfallprophylaxe und der Evaluation der Wirksamkeit einer Kombinationsbehandlung von Psychotherapie mit antidepressiver Medikation stehen noch aus.

Eating disorder prevention programs: A meta-analytic review

This meta-analysis of eating disorder prevention programs found that intervention effects ranged from an absence of any effects to reductions in current and future eating pathology. Certain effects persisted as long as 2 years and were superior to minimal-intervention control conditions. Larger effects occurred for selected (vs. universal), interactive (vs. didactic), and multisession (vs. single session) programs; for programs offered solely to females and to participants over age 15; for programs without psychoeducational content; and for trials that used validated measures. The results identify promising prevention programs and delineate sample, format, and design features that are associated with larger effects, but they suggest the need for improved methodological rigor and statistical modeling of trials and enhanced theoretical rationale for interventions.

Psychological and/or educational interventions for the prevention of depression in children and adolescents

BACKGROUND

Depression is the fourth most important disease in the estimation of the burden of disease Murray 1996 and is a common problem with prevalence rates estimated to be as high as 8% in young people. Depression in young people is associated with poor academic performance, social dysfunction, substance abuse, suicide attempts, and completed suicide (NHMRC 1997). This has precipitated the development of programmes aimed at preventing the onset of depression. This review evaluates evidence for the effectiveness of these prevention programmes.

OBJECTIVES

To determine whether psychological and/or educational interventions (both universal and targeted) are effective in reducing risk of depressive disorder by reducing depressive symptoms immediately after intervention or by preventing the onset of depressive disorder in children and adolescents over the next one to three years.

SEARCH STRATEGY

The Cochrane Depression, Anxiety and Neurosis Group trials register (August 2002), MEDLINE (1966 to December Week 3 2002), EMBASE (1980 to January Week 2 2003), PsychInfo (1886 to January Week 2 2003) and ERIC (1985 to December 2002) were searched. In addition, conference abstracts, the reference lists of included studies, and other reviews were searched and experts in the field were contacted.

SELECTION CRITERIA

Each identified study was assessed for possible inclusion by two independent reviewers based on the methods sections. The determinants for inclusion were that the trial include a psychological and/or educational prevention programme for young people aged 5 to 19 years-old, who did not meet DSM or ICD criteria for depression and/or did not fall into the clinical range on standardised, validated, and reliable rating scales of depression.

DATA COLLECTION AND ANALYSIS

The methodological quality of the included trials was assessed by two independent reviewers according to a list of pre-determined criteria, which were based on quality ratings devised by Moncrieff and colleagues (Moncrieff 2001). Outcome data was extracted and entered into Revman 4.2. Means and standard deviations for continuous outcomes and number of events for dichotomous outcomes were extracted where available. For trials where the required data were not reported or could not be calculated, further details were requested from first authors. If no further details were provided, the trial was included in the review and described, but not included in the meta-analysis. Results were presented for each type of intervention: targeted or universal interventions; and educational or psychological interventions and if data were provided, by gender. Where possible data were combined in meta-analyses to give a treatment effect across all trials. Sensitivity analysis were conducted on studies rated as "adequate" or "high" quality, that is with a score over 22, based on the scale by Moncrieff et al (Moncrieff 2001). The presence of publication bias was assessed using funnel plots.

MAIN RESULTS

Studies were divided into those that compared intervention with an active comparison or placebo (i.e. a control condition that resembles the intervention being investigated but which lacks the elements thought to be active in preventing depression) and those that used a "wait-list" or no intervention comparison group. Only two studies fell into the former category and neither showed effectiveness although one study was inadequately powered to show a difference and in the other the "placebo" contained active therapeutic elements, reducing the ability to demonstrate a difference from intervention. Psychological interventions were effective compared with non-intervention immediately after the programmes were delivered with a significant reduction in scores on depression rating scales for targeted (standardised mean difference (SMD) of -0.26 and a 95% confidence interval (CI) of -0.40 to -0.13 ) but not universal interventions (SMD -0.21, 95% CI -0.48, 0.06), with a significant effect maintained on pooling data (SMD -0.26, 95% CI -0.36, -0.15). While small effect sizes were reported, these were associated with a significant reduction in depressive episodes. The overall risk difference after intervention translates to "numbers needed to treat" (NNT) of 10. The most effective study is the targeted programme by Clarke (Clarke 2001) where the initial effect size of -0.46 is associated with an initial risk difference of -0.22 and NNT 5. There was no evidence of effectiveness for educational interventions. Reports of effectiveness for boys and girls were contradictory. The quality of many studies was poor, and only two studies made allocation concealment explicit. Sensitivity analysis of only high quality studies did not alter the results significantly. The only analysis in which there was significant statistical heterogeneity was the sub-group analysis by gender where there was variability in the response to different programmes for both girls and boys. For the most part funnel plots indicate findings are robust for short term effects with no publication bias evident. There are too few studies to comment on whether there is publication bias for studies reporting long-term (12-36 month) follow-up.

REVIEWER'S CONCLUSIONS

Although there is insufficient evidence to warrant the introduction of depression prevention programmes currently, results to date indicate that further study would be worthwhile. There is a need to compare interventions with a placebo or some sort of active comparison so that study participants do not know whether they are in the intervention group or not, to investigate the impact of booster sessions to see if effectiveness immediately after intervention can be prolonged, ideally for a year or longer, and to consider practical implementation of prevention programmes when choosing target populations. Until now most studies have focussed on psychological interventions. The potential effectiveness of educational interventions has not been fully investigated. Given the gender differences in prevalence, and the change in these that occurs in adolescence with a disproportionate increase in prevalence rates for girls, it is likely that girls and boys will respond differently to interventions. Although differences have been reported in studies in this review the findings are contradictory and a more definitive delineation of gender specific responses to interventions would be helpful.

Diagnosis and treatment of dysthymia in children and adolescents

Dysthymic disorder is a chronic depressive condition occurring in 0.6-4.6% of children and 1.6-8.0% of adolescents. Although symptoms are less severe than those observed in major depression, childhood-onset dysthymic disorder is characterised by a persistent and long-term depressed or irritable mood (mean episode duration 3-4 years), a worse outcome than major depression and, frequently, comorbid disorders (in around 50% of patients). Long-lasting depressive symptoms seem responsible for long-term disabling consequences on social skill learning, psychosocial functioning and consequent professional life, probably contributing to a higher risk of relapse or development of major depression. Consistently, the first episode of major depression occurs 2-3 years after the onset of dysthymic disorder, suggesting that the latter is one of the gateways to recurrent mood disorders. The primary aims of treatment for dysthymic disorder should be to resolve depressive symptoms, reduce the risk of developing other mood disorders over time and strengthen psychosocial functioning, especially in children and adolescents, in order to prevent the potentially serious sequelae of this disorder. As children with dysthymia often have multiple problems, interventions should involve multiple levels and measures: individual psychotherapy, family therapy/education and pharmacological treatment. Psychotherapeutic techniques, such as cognitive-behaviour therapy and interpersonal therapy, have been found to be efficacious interventions in treating children and adolescents with mild to moderate depression in studies including patients with either dysthmia or double depression. SSRIs are the first-line drug treatment for children and adolescents because of their safety, adverse effect profile and ease of use (the safety of paroxetine is currently under investigation). Several nonblind studies have shown the efficacy and good tolerability of SSRIs in children and adolescents with dysthymic disorder, but further research is needed to confirm their efficacy and that of newer antidepressants in the treatment of this disorder. Regardless of whether psychotherapeutic or medical treatments are planned, according to clinical experience, psychoeducational interventions and psychosocial support should be provided to parents and other caregivers during the acute treatment phase to help manage the child's irritable mood and foster a therapeutic alliance and better compliance with treatment. Unfortunately, no studies have focused on continuation treatment of paediatric dysthymic disorder. Given the chronicity, recurrence, psychosocial consequences and peculiar response pattern to treatment of dysthymic disorder, establishing effective 'acute' and 'continuation' interventions in this group of patients should be a priority in mental health management.

Depression and bipolar support alliance consensus statement on the unmet needs in diagnosis and treatment of mood disorders in children and adolescents

OBJECTIVE

To focus attention on the critical unmet needs of children and adolescents with mood disorders and to make recommendations for future research and allocation of healthcare resources.

METHOD

The 36-member Consensus Development Panel consisted of experts in child/adolescent or adult psychiatry and psychology, pediatrics, and mental health advocacy. Reviews of the literature concerning youth mood disorders were performed on the subjects of risk factors, prevention, diagnosis, treatment, and services delivery, and opinions and experiences of mental health advocates were obtained.

RESULTS

The Consensus Development Panel listened to presentations and participated in discussions. Independent workgroups of clinicians, scientists, and mental health advocates considered the evidence and prepared preliminary statements. Workgroup leaders presented drafts for discussion by the Consensus Development Panel. The final document was reviewed by the entire group and edited to incorporate input from all participants.

CONCLUSIONS

Evidence suggests high rates of unmet needs for children and adolescents with depression or bipolar disorder. Training is largely limited to child mental health specialists; general psychiatrists, pediatricians, and other primary care physicians receive little or no training. As a result, treatment patterns may reflect adult treatment plans that are not validated for youths. Effective treatments have been identified and some preliminary prevention models have been developed, but they are not yet widely applied. Patients experience limited exposure to clinicians adequately trained to address their problems and little information to guide care decisions, particularly concerning bipolar disorder. National efforts are required to restructure healthcare delivery and provider training and to immediately develop more advanced research on pathophysiology, prevention, and services delivery effectiveness.

Predictors of efficacy in depression prevention programmes. Meta-analysis

BACKGROUND

Worldwide, 340 million people are affected by depression, with high comorbid, social and economic costs.

AIMS

To identify potential predictors of effect in prevention programmes.

METHOD

A meta-analysis was made of 69 programmes to reduce depression or depressive symptoms.

RESULTS

The weighted mean effect size of 0.22 was effective for different age groups and different levels of risk, and in reducing risk factors and depressive or psychiatric symptoms. Programmes with larger effect sizes were multi-component, included competence techniques, had more than eight sessions, had sessions 60-90 min long, had a high quality of research design and were delivered by a health care provider in targeted programmes. Older people benefited from social support, whereas behavioural methods were detrimental.

CONCLUSIONS

An 11% improvement in depressive symptoms can be achieved through prevention programmes. Single trial evaluations should ensure high quality of the research design and detailed reporting of results and potential predictors.

Universelle, schulbasierte Prävention der Depression im Jugendalter: Ergebnisse einer Follow-Up-Studie

Zusammenfassung. Es werden Evaluationsergebnisse für eine universelle, schulische Präventionsmaßnahme zur Vorbeugung depressiver Symptome im Jugendalter vorgestellt. Bei der Präventionsmaßnahme handelt es sich um das in Tübingen entwickelte kognitiv-verhaltenstherapeutische Trainingsprogramm “Lust an realistischer Sicht & Leichtigkeit im sozialen Alltag“ (LARS & LISA; Pössel, Horn, Seemann & Hautzinger, in Druck ). In der evaluierten Version umfasste das Programm neun Sitzungen à 90 Minuten und wurde mit insgesamt 179 Schülern und Schülerinnen durchgeführt. Effekte wurden im Rahmen einer kontrollierten Studie mit einer Prä- und Post-Erhebung sowie einem Elf-Monats-Follow-Up überprüft. Als Ergebnis zeigen sich noch keine bedeutsamen Effekte auf die Depressionssymptomatik, jedoch bereits verschiedene positive Auswirkungen vor allem im Hinblick auf selbstwert-relevante kognitive Faktoren, als ein wichtiges Präventionsziel. Diese Effekte könnten wiederum präventiv auf eine spätere depressive Entwicklung wirken. Weiterhin ergab sich ein Trend für eine vorbeugende Wirkung des Programms auf aggressives Verhalten.

Prävention von Depression bei Kindern und Jugendlichen

Zusammenfassung. Depressive Störungen in Kindheit und Jugendalter sind unter anderem durch die hohe Prävalenz und Persistenz depressiver Störungen bis ins Erwachsenenleben, bedeutenden Komorbiditäten mit anderen psychischen Störungen und psychosozialen Problemen von hoher individueller und gesellschaftlicher Bedeutung. Aufgrund dieser Erkenntnisse haben verschiedene Autoren weltweit damit begonnen Präventionsprogramme zu entwickeln und zu evaluieren. In diesem Artikel werden die Probleme der Präventionsforschung und die Effektivität von Prävention bei Kindern und Jugendlichen dargestellt. Den Schwerpunkt bildet dabei ein Überblick über derzeit vorliegende Programme und deren Evaluationen unter besonderer Berücksichtigung von Programmen, die in deutscher Sprache vorliegen. Abschließend werden mögliche Entwicklungsrichtungen der zukünftigen Präventionsforschung aufgezeigt.

The prevention of depressive symptoms in rural school children: a randomized controlled trial

A controlled trial was conducted to evaluate a prevention program aimed at reducing depressive and anxious symptoms in rural school children. Seventh-grade children with elevated depression were selected. Nine primary schools (n = 90) were randomly assigned to receive the program, and 9 control schools (n = 99) received their usual health education classes. Children completed questionnaires on depression, anxiety, explanatory style, and social skills. Parents completed the Child Behavior Checklist (T. M. Achenbach, 1991). No intervention effects were found for depression. Intervention group children reported less anxiety than the control group after the program and at 6-month follow-up and more optimistic explanations at postintervention. Intervention group parents reported fewer child internalizing and externalizing symptoms at postintervention only.
