Major depression and dysthymia in children and adolescents: discriminant validity and differential consequences in a community sample

Adolescent depression and adult labor market marginalization: a longitudinal cohort study

Adolescent depression is linked to adult ill-health and functional impairment, but recent research suggests that individual/contextual factors might account for this association. This study aimed to test whether the clinical heterogeneity of adolescent depression is related to marginalization from the labor market across early to middle adulthood. Data were drawn from the Uppsala Longitudinal Adolescent Depression Study, a community-based cohort initially assessed with structured clinical interviews at age 16-17. The cohort (n = 321 depressed; n = 218 nondepressed) was followed up after 2+ decades through linkage to nationwide population-based registries. Outcomes included consecutive annual data on unemployment, work disability, social welfare recipiency, and a composite marginalization measure, spanning from age 21 to 40. Longitudinal associations were examined using logistic regression analysis in a generalized estimating equations modeling framework. Subsequent depressive episodes and educational attainment in early adulthood were explored as potential pathways. The results showed that adolescent depression was associated with adult marginalization outcomes, but the strength of association varied across depressed subgroups. Adolescents with persistent depressive disorder had higher odds of all outcomes, including the composite marginalization measure (adjusted OR = 2.0, 95% CI = 1.4-2.7, p < 0.001), and this was partially (31%) mediated by subsequent depressive episodes in early adulthood. Exploratory moderation analysis revealed that entry into tertiary education mitigated the association with later marginalization, but only for adolescents with episodic major depression. In conclusion, the risk for future labor market marginalization is elevated among depressed adolescents, particularly those presenting with persistent depressive disorder. Targeted interventions seem crucial to mitigate the long-lasting impact of early-onset depression.

Course of depression in a 10-year prospective study: Evidence for qualitatively distinct subgroups

The course of depressive disorders can vary considerable, with some individuals exhibiting a chronic course and poor outcomes, while others have a more episodic course and better outcomes. However, it is unclear whether degree of chronicity is continuous or reflects qualitatively distinct subgroups. Using data from a 5-wave, 10-year, naturalistic study of 127 depressed outpatients, we examined whether depression chronicity lies on a continuum or manifests natural boundaries. Spline regression was used to test 7 continuous and discontinuous models of the relationship between depression during the first follow-up interval and multiple outcomes at subsequent follow-ups. In order to further validate the findings, we also created empirically derived subgroups based on the results of the spline regression analyses and compared them on baseline clinical characteristics and long-term outcomes. There was a clear and consistent discontinuity indicating that for higher levels of chronicity during the first 30-month period, depression was linearly related to outcome; in contrast, for lower levels of chronicity, depression in the initial interval was unrelated to subsequent outcomes. The findings were strikingly consistent across the 4 follow-up evaluations using multiple outcomes and goodness-of-fit indices. In addition, the chronic group--as defined by the first follow-up period--exhibited more baseline chronic depression, anxiety and personality disorders, family history of dysthymia, and childhood adversity, and was more likely to attempt suicide and be hospitalized during follow-up, than the nonchronic group. Results suggest that there are qualitatively distinct classes of patients with more and less chronic depressions, and support the utility of longitudinal course as a means of parsing depression into more homogeneous subgroups.

Maternal and paternal psychosocial risk factors for clinical depression in a Norwegian community sample of adolescents

BACKGROUND

Parental characteristics can increase the risk of the development of adolescent depression. In this study, we focus on the parental factors of parents in a non-intact relationship, dissatisfaction with personal economy, physical illness or disability, and internalizing and externalizing problems. The aim is to examine which of these parental risk factors, separately for mothers and fathers, are associated with clinical depression in adolescents in a community sample.

METHODS

In the Youth and Mental Health study, 345 adolescents (mean age ± standard deviation 15.0 ± 0.6 years, range 13.8-16.6 years; 72.5% girls) and their parents (79% at least one parent) completed questionnaires and the diagnostic interview Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version (K-SADS-PL). Adolescents were classified into current major depressive disorder or dysthymia (n = 46), depression not otherwise specified (n = 48), or no depression (n = 251). The parental risk factors were based on interview and the Adult Self-Report. Risk factors associated with mothers (n = 267) and fathers (n = 167) were separately analyzed using ordinal logistic regression with current depression category as the dependent variable. All analyses were adjusted for youth sex and age.

RESULTS

Mothers' economical dissatisfaction, physical illness/disability, internalizing problems and externalizing problems were associated with adolescent current depression (P ≤ 0.02). Adjusting for all other factors, only mothers' internalizing problems (P < 0.001) remained significantly associated with adolescent depression. Fathers' risk factors were not associated with adolescent depression.

CONCLUSION

Characteristics of mothers are associated with adolescent current depression. Mothers' internalizing problems is independently strongly associated with increased risk of current adolescent depression. Clinicians should assess mothers' mental health when treating depressed adolescents.

Measurement properties of the Adolescent Quality of Life Mental Health Scale (AQOL-MHS)

BACKGROUND

This article presents data on the psychometric properties of a new measure, the Adolescent Quality of Life Mental Health Scale (AQOL-MHS), designed to measure quality of life in clinical samples of Latino adolescents aged 12-18 years. Participants were recruited in Puerto Rico to have one of five prevalent mental health disorders. The initial instrument development was achieved through a grounded theory approach with the use of focus groups and in-depth interviews.

METHODS

We conducted two stages of exploratory factor analyses (EFA) on 60 candidate items. The first stage was to establish the number of factors to extract, and the second was to improve the model by selecting the best items. A final EFA model retained 31 items and 3 factors labeled Emotional Regulation (11 items), Self-Concept (10 items) and Social Context (10 items).

RESULTS

The instrument showed good internal consistency, test-retest reliability, and construct validity. The hypotheses-driven validity tests were all supportive of the AQOL-MHS. There was evidence for convergent validity and discriminant validity, and results for known-groups' validity were overwhelmingly supportive of the ability of the instrument to identify differences between groups.

CONCLUSIONS

These preliminary findings support our conceptual model and the use of the AQOL-MHS domain and overall scores. We believe that this instrument will provide clinicians additional insight into the different aspects of quality of life that are important to adolescents with mental health problems. Therefore, we consider the AQOL-MHS a vital patient-centered outcome measure for assessment strategies in the prevention and treatment of this population.

Contextual socioeconomic status and mental health counseling use among US adolescents with depression

Most adolescents with depressive disorders do not receive any mental health services, even though effective treatments exist. Although research has examined numerous individual-level factors associated with mental health service use among depressed adolescents, less is known about the role of contextual factors. This study examines the relationship between contextual-level socioeconomic status (SES) and clinic-based mental health counseling use among US adolescents with high depressive symptoms in urban and suburban areas. Data from the first two waves of the National Longitudinal Study of Adolescent Health (N = 1,133; 59 % female) were analyzed using multilevel logistic models in which adolescents were nested within counties. After controlling for individual-level predisposing, enabling, and need characteristics, as well as county racial/ethnic composition, county SES was positively associated with clinic-based counseling use among depressed youth. A one standard deviation increase in the county affluence index was associated with 43 % greater odds of receiving any clinical counseling services. Furthermore, the positive relationship between county affluence and clinical counseling use was no longer significant after controlling for the county supply of mental health specialist physicians. The results indicate that county residential context is a key correlate of mental health service use among depressed adolescents, such that those who live in lower SES counties with fewer mental health specialists are less likely to receive treatment.

Shared decision making and behavioral impairment: a national study among children with special health care needs

Background

The Institute of Medicine has prioritized shared decision making (SDM), yet little is known about the impact of SDM over time on behavioral outcomes for children. This study examined the longitudinal association of SDM with behavioral impairment among children with special health care needs (CSHCN).

Method

CSHCN aged 5-17 years in the 2002-2006 Medical Expenditure Panel Survey were followed for 2 years. The validated Columbia Impairment Scale measured impairment. SDM was measured with 7 items addressing the 4 components of SDM. The main exposures were (1) the mean level of SDM across the 2 study years and (2) the change in SDM over the 2 years. Using linear regression, we measured the association of SDM and behavioral impairment.

Results

Among 2,454 subjects representing 10.2 million CSHCN, SDM increased among 37% of the population, decreased among 36% and remained unchanged among 27%. For CSHCN impaired at baseline, the change in SDM was significant with each 1-point increase in SDM over time associated with a 2-point decrease in impairment (95% CI: 0.5, 3.4), whereas the mean level of SDM was not associated with impairment. In contrast, among those below the impairment threshold, the mean level of SDM was significant with each one point increase in the mean level of SDM associated with a 1.1-point decrease in impairment (0.4, 1.7), but the change was not associated with impairment.

Conclusion

Although the change in SDM may be more important for children with behavioral impairment and the mean level over time for those below the impairment threshold, results suggest that both the change in SDM and the mean level may impact behavioral health for CSHCN.

Correlates associated with unipolar depressive disorders in a Latino population

BACKGROUND

This study reports the comparison and associations of demographic, clinical and psychosocial correlates with three unipolar depressive disorders: dysthymia (DYS), major depression (MD) and double depression (DD), and examines to which extent these variables predict the disorders.

SAMPLING AND METHOD

Previously collected data from 563 adults from a community in Puerto Rico were analyzed. One hundred and thirty individuals with DYS, 260 with MD and 173 with DD were compared by demographic variables, psychiatric and physical comorbidity, familial psychopathology, psychosocial stressors, functional impairment, self-reliance, problem recognition and formal use of mental health services. Multinomial regression was used to assess the association of the predictor variables with each of the three disorders.

RESULTS

Similarities outweighed the discrepancies between the disorders. The main differences observed were between MD and DD, while DYS shared common characteristics with both MD and DD. After other variables were controlled, anxiety, functional impairment and problem recognition most strongly predicted a DD diagnosis, while age predicted a DYS diagnosis.

CONCLUSION

MD, DYS and DD are not completely different disorders, but they do differ in key aspects that might be relevant for nosology, research and practice. A dimensional system that incorporates specific categories of disorders would better reflect the different manifestations of unipolar depressive disorders.

Longitudinal patterns of autonomic nervous system responding to emotion evocation among children with conduct problems and/or depression

Conduct disorder (CD) and depression co-occur at far greater levels than chance, despite largely separate diagnostic criteria. One potential shared mechanism of this comorbidity is emotion dysregulation, which characterizes both internalizing and externalizing disorders. Previous research demonstrates that respiratory sinus arrhythmia (RSA)-a peripheral biomarker of emotion regulation-is attenuated among children with CD, and among children with depression. However, few studies have examined biomarkers of emotion regulation as a function of heterotypic comorbidity. We evaluated longitudinal patterns of RSA and RSA reactivity to emotion evocation across three annual assessments among 207 children diagnosed at ages 8-12 years with CD (n = 30), depression (n = 28), comorbid CD and depression (n = 80), or no psychiatric condition (n = 69). Using continuous symptom counts as predictors, Depression × CD interactions were observed for both Time 1 resting RSA and Time 1 RSA reactivity. CD, depression, and their interaction were all associated with low resting RSA at Time 1. In addition, concurrently elevated CD and depression scores predicted the greatest RSA reactivity to emotion evocation. Psychopathology scores were unrelated to developmental changes in RSA and RSA reactivity over time.

Integrating etiological models of social anxiety and depression in youth: evidence for a cumulative interpersonal risk model

Models of social anxiety and depression in youth have been developed separately, and they contain similar etiological influences. Given the high comorbidity of social anxiety and depression, we examine whether the posited etiological constructs are a correlate of, or a risk factor for, social anxiety and/or depression at the symptom level and the diagnostic level. We find core risk factors of temperament, genetics, and parent psychopathology (i.e., depression and anxiety) are neither necessary nor sufficient for the development of social anxiety and/or depression. Instead, aspects of children's relationships with parents and/or peers either mediates (i.e., explains) or moderates (i.e., interacts with) these core risks being related to social anxiety and/or depression. We then examine various parent- and peer-related constructs contained in the separate models of social anxiety and depression (i.e., parent-child attachment, parenting, social skill deficits, peer acceptance and rejection, peer victimization, friendships, and loneliness). Throughout our review, we report evidence for a Cumulative Interpersonal Risk model that incorporates both core risk factors and specific interpersonal risk factors. Most studies fail to consider comorbidity, thus little is known about the specificity of these various constructs to depression and/or social anxiety. However, we identify shared, differential, and cumulative risks, correlates, consequences, and protective factors. We then put forth demonstrated pathways for the development of depression, social anxiety, and their comorbidity. Implications for understanding comorbidity are highlighted throughout, as are theoretical and research directions for developing and refining models of social anxiety, depression, and their comorbidity. Prevention and treatment implications are also noted.

Socially Prescribed and Self-Oriented Perfectionism as Predictors of Depressive Diagnosis in Preadolescents

Perfectionism has been shown to be related to depressive symptomatology in both adult and child populations. However, there are no known studies of levels of socially prescribed (SPP) and self-oriented perfectionism (SOP) in nonclinical children versus those with a clinically diagnosed depressive disorder. Therefore, the aim of the current study was to examine SPP and SOP as predictors of depressive diagnoses in a sample of 10- to 11-year-old children. Seven hundred and eighty-six children (390 boys, 396 girls) from primary schools in low socio-economic metropolitan areas completed the Children's Depression Inventory (CDI) and the Child and Adolescent Perfectionism Scale (CAPS) as part of a larger study. Children who scored above the clinical cut-off for the CDI also completed part of the Diagnostic Interview for Children and Adolescents–IV. Fifty children met criteria for a diagnosis of a depressive disorder. Binary logistic regression analysis was used to predict diagnostic status from SPP, SOP, gender, and intervention group. SPP was the only significant predictor of diagnostic status. Implications for the treatment and prevention of childhood depression are discussed.

Regulação emocional em crianças com e sem sintomas de depressão

O objetivo do presente trabalho é avaliar a regulação emocional de crianças com e sem sintomas de depressão. A amostra foi composta por 54 alunos de 3ª e 4ª séries do ensino fundamental, sendo 27 com sintomas depressivos (G1) e 27 sem sintomatologia (G2). Utilizou-se o Inventário de Depressão Infantil - CDI (Kovacs, 1992) e a Entrevista com Pranchas para Avaliação da Regulação Emocional de Alunos do Ensino Fundamental - EPRE (Cruvinel & Boruchovitch, 2004). Os resultados indicaram que os dois grupos relataram usar estratégias semelhantes para lidar com as diferentes emoções, no entanto, os alunos do G1 sentem mais frequentemente tristeza e raiva e têm mais dificuldade na percepção de emoções como tristeza, medo e alegria. Tendo em vista os resultados obtidos, discute-se a importância do desenvolvimento de programas orientados para a prevenção e, especialmente, para a intervenção em depressão na infância e na adolescência, visando não só reduzir a prevalência de depressão, mas também melhorar as estratégias de regulação emocional e depressão e o bem-estar psicológico dos alunos do ensino fundamental.

Epidemiology of depression in an urban population of Turkish children and adolescents

BACKGROUND

In Turkey, studies of childhood depression have been limited to those using only scales.

METHODS

This is a two-stage cross-sectional epidemiological study. Three schools in Fatih, Istanbul, Turkey were selected by cluster sampling. The study included 1482 students between the fourth and eighth grades. The Child Depression Inventory (CDI) was used for screening in the first stage. According to test results, 320 children were interviewed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version. Depressive disorders were diagnosed in 62 students, constituting the case group. The control group was matched to the case group on school, grade, age, gender, and socioeconomic status (SES).

RESULTS

The prevalence rate was 4.2% for some form of depressive disorder, 1.55% for major depressive disorder, 1.75% for dysthymic disorder, 0.26% for double depression, and 0.60% for depressive disorder-not otherwise specified. According to the logistic regression analysis, increasing age, having a working mother and low maternal education were all positively associated with CDI score. Low SES, perception of paternal health and relations with father as negatively, low popularity and behavior subscales of the Piers-Harris self-concept scale, and high trait anxiety were associated with the presence of a depressive disorder.

LIMITATIONS

Parents were not included in the diagnostic interviews.

CONCLUSIONS

Dysthymic disorder was the most common depressive disorder. Low maternal education, low SES, dysfunctional interaction with the father, anxiety, and low self-esteem, which were all associated with depression, may be the target of interventions for prevention and treatment of depression.

Prevalence and characteristics of depressive disorders in early adolescents in central Norway

BACKGROUND

Prevalence of depressive disorders among adolescents has varied across studies. The present study aims to assess current and lifetime prevalence and characteristics of adolescent Major Depressive Disorder (MDD), Dysthymia and Depression NOS among adolescents in Central Norway in addition to socio-demographics and use of mental health care.

METHOD

In the Youth and Mental Health Study a representative sample of 2432 junior high school students (mean age 14.9 years, SD = 0.6) from two counties in Central Norway were screened with the Mood and Feelings Questionnaire (MFQ). A subset of 345 of these adolescents (72.5% girls), 220 high scorers (MFQ = > 26), 74 middle scorers (MFQ 7-25), and 50 low scorers (MFQ < 7), 1 unknown score, were drawn and interviewed with the Kiddie SADS-PL (Present-Life Version). In all, 79% had parental interviews as well. All estimates of prevalence rates and population shares were weighted back using a sandwich estimator to yield true population estimates.

RESULTS

Almost one in four subjects (23%) had life-time depression. Prevalences of current Major Depressive Disorder (MDD), Dysthymia and "Double depression" were 2.6%, 1.0% and 0.6%, respectively, and for Depression NOS 6.3%.All depressive disorders were characterized by long duration of episodes with large variations, and for any depressive disorder onset before 12 years of age. In multivariate analyses MDD and Dysthymia were most strongly associated with gender and not living with both biological parents. There was no gender difference for Depression NOS. Although a considerable number of depressed subjects had received mental health care, the reason for contact with services was seldom due to affective symptoms. Less than 20% had been in contact with specialist mental health services.

CONCLUSION

High rates of Depression NOS, early onset of depressive episodes, long duration, and low use of specialized services point to the need for improved diagnostic assessment and treatment for young individuals.

Ethnic differences in perceived impairment and need for care

Latino children in the U.S. have high rates of unmet need for mental health services, perhaps due to biased perceptions of impairment and need for care by parents and providers. We tested this argument using an experimental vignette design. Vignettes described children with problems that varied on severity (mild vs. serious), nature of the problem (internalizing vs. externalizing), as well as gender and ethnicity (Latino vs. Anglo). Raters were Latino and Anglo parents (N = 185) and providers (N = 189). Vignettes with Latino names were viewed as more impaired by both parents and providers, and this effect was significantly stronger in Latino vignettes with less severe problems. Severity and Latino features of vignettes also interacted with judgments of need for service. At higher severity, vignettes with Anglo names were judged to need service more than vignettes with Latino names, despite the same judged levels of impairment. Results are discussed in the light of the unmet need for Latinos.

The epidemiology of chronic major depressive disorder and dysthymic disorder: results from the National Epidemiologic Survey on Alcohol and Related Conditions

OBJECTIVE

To examine the prevalence of chronic major depressive disorder (CMDD) and dysthymic disorder, their sociodemographic correlates, patterns of 12-month and lifetime psychiatric comorbidity, lifetime risk factors, psychosocial functioning, and mental health service utilization.

METHOD

Face-to-face interviews were conducted in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (n = 43,093).

RESULTS

The 12-month and lifetime prevalences were greater for CMDD (1.5% and 3.1%, respectively) than for dysthymic disorder (0.5% and 0.9%, respectively). Individuals with CMDD and dysthymic disorder shared most sociodemographic correlates and lifetime risk factors for major depressive disorder. Individuals with CMDD and dysthymic disorder had almost identically high rates of Axis I and Axis II comorbid disorders. However, individuals with CMDD received higher rates of all treatment modalities than individuals with dysthymic disorder.

CONCLUSIONS

Individuals with CMDD and dysthymic disorder share many sociodemographic correlates, comorbidity patterns, risk factors, and course. Individuals with chronic depressive disorders, especially those with dysthymic disorder, continue to face substantial unmet treatment needs.

Clinical characteristics of depression among adolescent females: a cross-sectional study

BACKGROUND

Adolescents rarely seek psychiatric help; they even hesitate to disclose their feelings to their parents. However; the adolescents especially the females experience depressive symptoms more frequently than general population. Do they experience classic depressive symptoms? Are there symptoms specific to this subpopulation?

AIM OF THE STUDY

Through this study, the authors aimed to estimate the prevalence of depressive disorders in Egyptian adolescent female students. They also expected a characteristic profile of symptoms for the adolescent females. However available literature provides no guidance in the description of this profile of symptoms.

METHODS

A number of 602 adolescent females were interviewed, and subjected to General Health Questionnaire (GHQ); Children Depression Inventory (CDI), Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I), then Hamilton Rating Scale for Depression (Ham-D). Results were analyzed by the use of SPSS-15.

RESULTS

The study revealed the prevalence of depression in the sample of the study to be 15.3% (measured by CDI), and 13.3% (measured by SCID-I). Fatigue was the most common presenting depressive symptom (81.3%), in addition to other emotional, cognitive and physiological symptoms. Suicidal ideations were the most common suicidal symptoms in depressed adolescent females (20%), with 2.5% serious suicidal attempts.

CONCLUSIONS

The somatic symptoms were by far the most common presenting symptom for female adolescents suffering from depressive disorders. Depressive phenomena including unexplained fatigue, decreased energy, psychomotor changes, lack of concentration, weight changes and suicidal ideations may be the presenting complaints instead of the classic sad mood.

Morbidity in obese adolescents who meet the adult National Institutes of Health criteria for bariatric surgery

PURPOSE

Some have suggested that the criteria for weight loss surgery in adolescents be stricter than those currently recommended for adults by the National Institutes of Health (NIH). The aim of the current study is to define the characteristics of adolescents who meet NIH consensus criteria for bariatric surgery in adults to determine their level of morbidity.

MATERIALS AND METHODS

Using the Medical Expenditure Panel Survey 2000-2004, children designated as meeting NIH criteria were 13 to 17 years of age with (1) a body mass index >or=40 or (2) a body mass index >35, and one or more comorbidity. We contrasted surgery candidates with noncandidates. We examined items that comprise a screener for identifying children with special health care needs. The Columbia Impairment Scale (CIS) was used to assess child functioning.

RESULTS

There were 134 children identified as candidates for bariatric surgery and 4736 noncandidates in the same age range. Candidates were more likely to have special health care needs (36% vs 23%) and more likely to have a CIS above 16 (34% vs 16%). Candidates for weight loss surgery were 2.36 times as likely to have a CIS score of 16 or higher and 1.87 times as likely to be identified as a child with special health care needs (P <or= .001).

CONCLUSIONS

We conclude that adolescents who meet NIH consensus criteria for weight loss surgery in adults require specialized health services and have functional impairment. Thus, we advocate the use of the standard adult criteria defined by the NIH as the initial screening requirements so that enhanced access to weight loss surgery for morbidly obese adolescents may be achieved.

Prenatal dysthymia versus major depression effects on maternal cortisol and fetal growth

To determine differences between pregnant women diagnosed with Dysthymia versus Major Depression, depressed pregnant women (N=102) were divided by their diagnosis into Dysthymic (N=48) and Major Depression (N=54) groups and compared on self-report measures (depression, anxiety, anger, daily hassles and behavioral inhibition), on stress hormone levels (cortisol and norepinephrine), and on fetal measurements. The Major Depression group had more self-reported symptoms. However, the Dysthymic group had higher prenatal cortisol levels and lower fetal growth measurements (estimated weight, femur length, abdominal circumference) as measured at their first ultrasound (M=18 weeks gestation). Thus, depressed pregnant women with Dysthymia and Major Depression appeared to have different prenatal symptoms.

Social competence and social support as mediators between comorbid depressive and conduct problems and functional outcomes in middle school children

This study examined the roles of social competence and social support as potential mediators of the association between psychopathology and functional outcomes in a middle school sample (n=521). Participants were stratified into four psychopathology risk groups (depression only, conduct problems only, comorbid depression and conduct problems, low symptoms) based on screening during early 6th grade. Functional outcomes were 6th grade point average (GPA) and parent rating of global adaptive functioning in their 7th grade student. Low levels of social competence were found to mediate the association between symptoms and both lower grades and global functioning for adolescents with depressive symptoms alone and with comorbid symptoms, but not for those with conduct problems alone. Lack of social support mediated the association between psychiatric symptoms and lower grades for adolescents with depression alone and comorbid symptoms, but not for those with conduct problems alone. These findings suggest that intervention to improve social competence and social support may enhance functional outcomes, especially for youth with depressive symptoms or comorbid depressive and conduct symptoms.

Differences in the clinical characteristics of adolescent depressive disorders

Our objective was to analyze differences in clinical characteristics and comorbidity between different types of adolescent depressive disorders. A sample of 218 consecutive adolescent (ages 13-19 years) psychiatric outpatients with depressive disorders was interviewed for DSM-IV Axis I and Axis II diagnoses. We obtained data by interviewing the adolescents themselves and collecting additional background information from the clinical records. Lifetime age of onset for depression, current episode duration, frequency of suicidal behavior, psychosocial impairment, and the number of current comorbid psychiatric disorders varied between adolescent depressive disorder categories. The type of co-occurring disorder was mainly consistent across depressive disorders. Minor depression and dysthymia (DY) presented as milder depressions, whereas bipolar depression (BPD) and double depression [DD; i.e., DY with superimposed major depressive disorder (MDD)] appeared as especially severe conditions. Only earlier lifetime onset distinguished recurrent MDD from first-episode MDD, and newly emergent MDD appeared to be as impairing as recurrent MDD. Adolescent depressive disorder categories differ in many clinically relevant aspects, with most differences reflecting a continuum of depression severity. Identification of bipolarity and the subgroup with DD seems especially warranted. First episode MDD should be considered as severe a disorder as recurring MDD.

Sintomas depressivos em crianças: estudos com duas versões do CDI

O objetivo deste estudo foi identificar o número de crianças com sintomas depressivos em duas amostras de estudantes da cidade de campinas. Utilizou-se, no estudo 1, a versão brasileira do Inventário de Depressão Infantil (CDI) e, no estudo 2, a versão original. Do estudo 1, realizado em 2001, participaram 169 estudantes de 3ª, 4ª e 5ª séries, e, do estudo 2, conduzido em 2005, 157 alunos de 3ª e 4ª séries. A prevalência de sintomatologia depressiva no estudo 1 foi de 3,55%, e, no estudo 2, de 17%. Em ambos os estudos, não foram encontradas diferenças significativas entre a média no CDI em relação às variáveis demográficas. conclui-se pela necessidade de mais estudos nacionais de prevalência no ensino fundamental e de esforços direcionados não só para a identificação dos fatores de risco, de proteção e das variáveis associadas mas também do refinamento dos instrumentos de medidas da depressão infantil.

Impact of comorbid anxiety in an effectiveness study of interpersonal psychotherapy for depressed adolescents

OBJECTIVE

To assess the impact of comorbid anxiety on treatment for adolescent depression in an effectiveness study of interpersonal psychotherapy for depressed adolescents (IPT-A).

METHOD

A randomized clinical trial was conducted from April 1, 1999, through July 31, 2002. Sixty-three depressed adolescents, ages 12 to 18, received either IPT-A or treatment as usual delivered by school-based mental health clinicians. Adolescents with and without probable comorbid anxiety disorders were compared on depression and overall functioning. All analyses used an intent-to-treat design.

RESULTS

Comorbid anxiety was associated with higher depression scores at baseline (p <.01) and poorer depression outcome posttreatment (p <.05). IPT-A was nonsignificantly more effective in treating the depression of adolescents with comorbid anxiety (p =.07). Adolescents whose depression and functioning improved during the course of treatment also showed an improvement in anxiety (p <.01), largely irrespective of treatment condition.

CONCLUSIONS

Adolescents with comorbid depression and anxiety present with more severe depression and may be more difficult to treat. Structured treatments like IPT-A may be particularly helpful for comorbidly depressed adolescents as compared to supportive therapy.

Characteristics of internalizing and externalizing disorders in medication-naive, clinically referred children with attention deficit hyperactivity disorder, combined type and dysthymic disorder

OBJECTIVE

Internalizing and externalizing disorders are frequently comorbid with attention deficit hyperactivity disorder, combined type (ADHD-CT) and dysthymic disorder (DD) in referred primary school-age children, yet there has been relatively little systematic research of the nature of these comorbid disorders. We describe the characteristics of parent- and child-reported internalizing and externalizing disorders in primary school-age children with ADHD-CT and DD.

METHOD

A cross-sectional study of 45 clinically referred medication naive children with ADHD-CT and DD, examining parent and child reports of internalizing and externalizing disorders, defined categorically and dimensionally.

RESULTS

Generalized anxiety disorder and separation anxiety disorder were increased in the DD groups, whether ADHD-CT was present or not. Major depressive disorder was increased in the ADHD-CT and DD group compared to the ADHD-CT alone and the DD alone groups. Conduct disorder was increased in the ADHD-CT alone group compared to the DD with and without ADHD-CT groups. Verbal and fullscale IQ were increased in the DD groups, whether ADHD-CT was present or not, compared to the ADHD-CT alone group.

CONCLUSIONS

There is emerging evidence that DD and anxiety may represent a different phenotypic expression of a common underlying aetiological process, while the co-occurrence of ADHD-CT and anxiety disorders remains unclear. Only the ADHD-CT and DD group is significantly associated with major depressive disorder, which suggests an additive effect. In contrast, conduct disorder and decreased verbal and fullscale IQ are only associated with the ADHD-CT group, which may suggest a protective effect of DD when comorbid with ADHD-CT. From a research perspective, it is important to confirm these found associations in larger samples derived from epidemiological populations.

Ten-year review of rating scales, VII: scales assessing functional impairment

OBJECTIVE

This is the seventh in a series of 10-year reviews of rating scales. Here the authors present scales measuring functional impairment, a sequela of mental illness. The measurement of functional impairment has assumed importance with the recognition that symptom resolution does not necessarily correlate with functional improvement.

METHOD

The authors reviewed functional impairment from multiple sources over the past 20 years. Thus, this article includes a variety of scales ranging from those that have been subject to critical review with strong psychometric support to those that have not been critically reviewed but are in widespread use to those that are still finding their niche.

RESULTS

These scales represent a continuum of constructs from symptoms to functional impairment to contextual factors that affect youths' functioning. Most older scales have focused on developmentally delayed youths. Newer scales strive to measure functional impairment separate from symptomatology. Some newer scales are also keyed to determination of level of service need.

CONCLUSIONS

Scales measuring functional impairment can elucidate the impact of illness on youths, identify targets for treatment, determine service needs, and monitor treatment effectiveness. These scales are widely used in community mental health and health service delivery. They can assist in providing evidence-based treatment.

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.

Diagnosis and treatment of chronic depression in children and adolescents

Chronic unipolar depression is being increasingly recognized in general psychiatry as a particularly severe form of depressive illness that leads to significant symptomatology, prolonged suffering, and prolonged functional impairment in a variety of domains, including educational/vocational dysfunction as well as interpersonal impairment. Recent research on treatment interventions for adult patients with chronic depressions suggests that standard treatments for depressive illness may need modification to benefit patients with chronic illness. Little attention at this point has been given to the problem of chronic depression in children and adolescents. Many adults with chronic depressive disorders had onset of depression in their childhood or adolescence, making early identification of this form of illness a priority. The authors present a comprehensive review of emerging literature in the assessment, clinical course, and treatment of chronic forms of unipolar depression in youth. They then develop summary recommendations for the assessment and treatment of this type of mood disorder in youth, based on the currently available research and common sense clinical experience.

Phenomenology and comorbidity of dysthymic disorder in 100 consecutively referred children and adolescents: beyond DSM-IV

OBJECTIVE

Diagnostic criteria and nosological boundaries of juvenile dysthymic disorder (DD) are under-researched. Two different sets of diagnostic criteria are still discussed in the DSM-IV, the first giving major weight to somatic and vegetative symptoms and the second, included in the appendix, to more affective and cognitive symptoms. The aim of this study was to describe prototypical symptomatology and comorbidity of DD, according to DSM-IV criteria, in a consecutive series of referred children and adolescents, as a function of age and sex.

METHOD

One hundred inpatients and outpatients (36 children and 64 adolescents, 57 males, 43 females, age range 7 to 18 years, mean age 13.3 years) received a diagnosis of DD without comorbid major depressive disorder (MDD), using historical information, the Diagnostic Interview for Children and Adolescents-Revised (DICA-R), and symptoms ratings according to the DSM-IV criteria.

RESULTS

Irritability, low self-esteem, fatigue or loss of energy, depressed mood, guilt, concentration difficulties, anhedonia, and hopelessness were present in more than 50% of subjects. Differences in symptomatic profile between male and female patients were not significant. Anxiety disorders were commonly comorbid with DD, mainly generalized anxiety disorder, simple phobias, and in prepuberal children, separation anxiety disorder. Externalizing disorders were reported in 35% of the patients, with higher prevalence in male patients. Adolescents showed more suicidal thoughts and anhedonia than children.

CONCLUSIONS

The clinical picture of early-onset DD we found, based entirely on a pure sample without current and past MDD, is not totally congruent with the diagnostic criteria according to DSM-IV. A more precise definition of the clinical picture may help early diagnosis and prevention of superimposed mental disorders.

Depression in adolescence

Major depression is a common mental health disorder in adolescents that predicts a significant risk for recurrence in adulthood. Suicide is the third most frequent cause of deaths in this age group, and depression is a significant risk factor for suicidal ideation and attempts. Risks for depression and suicidal ideation are reviewed, and subtypes of depression are discussed. Difficulties associated with identification of depression and suicidal ideation in adolescents and biologic therapies for adolescent depression are reviewed.

Phenomenology, psychosocial correlates, and treatment seeking in major depression and dysthymia of adolescence

OBJECTIVE

To compare phenomenology, psychosocial correlates, and treatment seeking in DSM-Itt-R major depression and dysthymia among adolescents diagnosed as cases in a community-based study.

METHOD

A self-report questionnaire, including psychosocial data, life events, eating behaviors, depressive symptoms, substance use, pathological behaviors, and family and school functioning was administered to a nonselected sample (N = 3,287, 93.2% of targeted population) of adolescents aged 11 to 20 years from several Haute-Marne communities in France in 1988-1989. Subgroups of subjects (n = 205, 84.7% of eligible subjects) were interviewed with a structured diagnostic schedule, and adolescents with major depression (n = 49), dysthymia (n = 21) and controls (n = 135) were compared.

RESULTS

Nearly 30% of controls had at least one current symptom of depression. Patterns of affective symptoms were similar in major depression and dysthymia, but significant differences emerged in comorbid conditions (more anxiety disorders, suicidal behaviors, and alcohol intoxications associated with major depression) and stressor at onset (more severe in major depression). Experiences of loss during the prior 12 months were associated with both forms of affective disorder, while poor family relationships were specific correlates of dysthymia. In contrast, peer relationships and pathological behaviors did not differ between depressed subjects and controls. Although psychosocial functioning was significantly impaired in both groups of depressed adolescents, treatment seeking was limited to 34.7% for major depressive subjects and 23.8% for dysthymic subjects.

CONCLUSION

The results provide evidence that major depression and dysthymia in adolescence are equally severe but may have distinct patterns in associated factors. Despite free access to health care, the rate of treatment seeking for mood disorders in France is similar to that reported in U.S. studies.

Affective illness in children and adolescents: patterns of presentation in relation to pubertal maturation and family history

Affective illness is now recognized as a common problem in all age groups, and the various patterns have been well documented in adults. The objective of this study was to evaluate the patterns of affective illness in children and determine changes with increasing age and family history. One hundred children/adolescents with affective illness (72 boys and 28 girls; age range 2-20 years; mean age 10 years), who were consecutively referred to the Pediatric Behavioral Neurology Program, Children's Medical Center at Dallas, were evaluated for the pattern and course of affective illness symptoms, family history, and pubertal stage. Seven patterns of affective illness were identified. In the 65 prepubertal children (Tanner stage 1), disorders with hypomanic/manic symptomatology were most common (47/65, 72%): mania (2/65, 3%), hypomania (8/65, 12%), cyclothymia (11/65, 17%), juvenile rapid-cycling bipolar disorder/ultradian cycling bipolar disorder (8/65, 12%), and dysthymia with bipolar features (18/65, 28%). In contrast, the 26 fully pubertal adolescents (Tanner stages 3-5) had a predominance of patterns with only depressive symptomatology (16/26, 61%): dysthymia (4/26, 15%) and depression (12/26, 46%), along with juvenile rapid-cycling bipolar disorder/ultradian cycling bipolar disorder (6/26, 23%). Affective illness, alcoholism, and drug abuse were prominent in the family histories, regardless of the child's pattern of symptoms. Family histories of character disorder and Briquet's syndrome were also common, but thought disorder, suicide, and homicide were infrequent. This study supports the clinical observation that the presentation of affective illness changes with age: manic features predominate in younger children, whereas depressive symptomatology is more evident with pubertal maturation.
