Prevalence of DSM-IV disorders, comorbidity and impairment in 3-year-old Spanish preschoolers

Purpose

The goal is to examine the prevalence, comorbidity and impairment of DSM-IV disorders in 3-year-old children from the Spanish general population.

Method

A sample of 1,341 3-year-old preschoolers were randomly selected and screened for a double-phase design. In total, 622 families were assessed with a diagnostic semi-structured interview and functional impairment measures.

Results

Prevalence of any diagnosis was 29.9 %, the most prevalent disorders being primary insomnia (11.7 %) and oppositional defiant disorder (ODD) (6.9 %). There were no sex differences in the prevalence. One-third of the families had sought professional help for the child’s symptoms, and 9.4 % received treatment (4.4 % psychological and 2.1 % pharmacological). After controlling for other comorbidities, ADHD was significantly associated with ODD, CD, insomnia and social phobia; ODD was associated with CD, separation anxiety, specific phobia and major depression. Diagnostic categories were associated with impairment, family burden, seeking professional help and receiving treatment. A diagnosis was more frequent in children of low socioeconomic status, born outside Spain, from one-parent families, with younger parents and with parents of lower educational level.

Conclusions

Psychopathology, comorbidity and associated factors are very frequent from age three, suggesting a need for efforts of detection, prevention and treatment in the different societies.     

Lifetime risk and age of onset distributions of psychiatric disorders: analysis of national sample survey in South Korea

Background

The present study represents the first attempt at examining variation across Korean cohorts with respect to lifetime risk of DSM-IV psychiatric disorders.

Aims

To present data on lifetime prevalence and projected lifetime risk, as well as age of onset (AOO) and demographic correlates of DSM-IV psychiatric disorders as assessed in the nationwide survey of a representative sample of Korean adults.

Method

The survey was based on a multistage area probability sample of non-institutionalized Koreans aged 18–64?years. The Korean version of the Composite International Diagnostic Interview 2.1 (K-CIDI 2.1) was administered by lay interviewers.

Results

Lifetime prevalence of any disorder was 24.6%. Alcohol abuse (9.2%), alcohol dependence (7.0%), major depressive disorder (5.6%), specific phobia (3.8%), and GAD (1.6%) were the most common disorders. The median AOO was earliest for anxiety disorders (age 29), latest for mood disorders (age 47), and intermediate for alcohol use disorders (age 31). Compared to observed lifetime prevalence (24.6%), 35.0% of Koreans will eventually experience one of these disorders. Further, half of the population who present with a psychiatric disorder do so by the age of 32 and younger cohorts are at greater risk for most disorders.

Conclusions

About one-third of the Korean adult population will meet the criteria for a DSM-IV psychiatric disorder at some time during their life. The median age of onset varies from disorder to disorder and younger cohorts appear to be at greater risk for most disorders.     

Psychopathology and substance abuse in parents of young children with attention-deficit/hyperactivity disorder

OBJECTIVE: To compare the prevalence of psychological disorders in parents of young children with and without attention-deficit/hyperactivity disorder (ADHD) and comorbid disruptive behavior disorders (DBD). METHOD: Subjects included 98 three- to seven-year-old children with DSM-IV ADHD (68 with ADHD and comorbid oppositional defiant or conduct disorder [ADHD+ODD/CD]) and 116 non-ADHD comparison children recruited in 1995-96 during the first wave of a longitudinal study. Biological mothers were administered interviews to assess ADHD and DBD in their children and mood, anxiety, and substance use disorders in themselves. In addition, they were queried about symptoms of childhood ADHD and DBD, and antisocial personality disorder in themselves and their children's biological fathers. RESULTS: Child ADHD was associated with increased rates of maternal and paternal childhood ADHD relative to comparison children. Child ADHD+ODD/CD was associated with maternal mood disorders, anxiety disorders, and stimulant/cocaine dependence, and paternal childhood DBD. Mothers of children with ADHD+ODD/CD also reported increased drinking problems in their children's fathers. CONCLUSIONS: These findings indicate that many young children with ADHD, particularly those with comorbid ODD/CD, require comprehensive services to address both their ADHD and the mental health needs of their parents.     

Dietary intake of fish, omega-3, omega-6 polyunsaturated fatty acids and vitamin D and the prevalence of psychotic-like symptoms in a cohort of 33 000 women from the general population

Background

ADHD is a common and disabling disorder, with an increased risk for coexisting disorders, substance abuse and delinquency. In the present study, we aimed at exploring ADHD and criminality. We estimated the prevalence of ADHD among longer-term prison inmates, described symptoms and cognitive functioning, and compared findings with ADHD among psychiatric outpatients and healthy controls.

Methods

At Norrtälje Prison, we approached 315 male inmates for screening of childhood ADHD by the Wender Utah Rating Scale (WURS-25) and for present ADHD by the Adult ADHD Self-Report Screener (ASRS-Screener). The response rate was 62%. Further, we assessed 34 inmates for ADHD and coexisting disorders. Finally, we compared findings with 20 adult males with ADHD, assessed at a psychiatric outpatient clinic and 18 healthy controls.

Results

The estimated prevalence of adult ADHD among longer-term inmates was 40%. Only 2 out of 30 prison inmates confirmed with ADHD had received a diagnosis of ADHD during childhood, despite most needed health services and educational support. All subjects reported lifetime substance use disorder (SUD) where amphetamine was the most common drug. Mood and anxiety disorders were present among half of subjects; autism spectrum disorder (ASD) among one fourth and psychopathy among one tenth. Personality disorders were common; almost all inmates presented conduct disorder (CD) before antisocial personality disorder (APD). Prison inmates reported more ADHD symptoms during both childhood and adulthood, compared with ADHD psychiatric outpatients. Further, analysis of executive functions after controlling for IQ showed both ADHD groups performed poorer than controls on working memory tests. Besides, on a continuous performance test, the ADHD prison group displayed poorer results compared with both other groups.

Conclusions

This study suggested ADHD to be present among 40% of adult male longer-term prison inmates. Further, ADHD and coexisting disorders, such as SUD, ASD, personality disorders, mood- and anxiety disorders, severely affected prison inmates with ADHD. Besides, inmates showed poorer executive functions also when controlling for estimated IQ compared with ADHD among psychiatric outpatients and controls. Our findings imply the need for considering these severities when designing treatment programmes for prison inmates with ADHD.     

Parsing the familiality of oppositional defiant disorder from that of conduct disorder: a familial risk analysis

Background

Family risk analysis can provide an improved understanding of the association between attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD), attending to the comorbidity with conduct disorder (CD).

Methods

We compared rates of psychiatric disorders in relatives of 78 control probands without ODD and CD (Control, N = 265), relatives of 10 control probands with ODD and without CD (ODD, N = 37), relatives of 19 ADHD probands without ODD and CD (ADHD, N = 71), relatives of 38 ADHD probands with ODD and without CD (ADHD + ODD, N = 130), and relatives of 50 ADHD probands with ODD and CD (ADHD + ODD + CD, N = 170).

Results

Rates of ADHD were significantly higher in all three ADHD groups compared to the Control group, while rates of ODD were significantly higher in all three ODD groups compared to the Control group. Evidence for co-segregation was found in the ADHD + ODD group. Rates of mood disorders, anxiety disorders, and addictions in the relatives were significantly elevated only in the ADHD + ODD + CD group.

Conclusions

ADHD and ODD are familial disorders, and ADHD plus ODD outside the context of CD may mark a familial subtype of ADHD. ODD and CD confer different familial risks, providing further support for the hypothesis that ODD and CD are separate disorders.     

Prevalence and treatment of 12-month DSM-IV disorders in the Northern Ireland study of health and stress

Purpose

Prior to the current Northern Ireland Study of Health and Stress there have been no epidemiological studies which estimate the prevalence and treatment of mental health disorders across Northern Ireland based on validated diagnostic criteria. This paper provides the first nationally representative estimates of 12-month DSM-IV anxiety, mood, impulse-control and substance disorders. Severity, demographic correlates, treatment and treatment adequacy of 12-month disorders are also examined.

Methods

Data were derived from a nationally representative face-to-face household survey of 4,340 participants (2,441 females and 1,899 males) aged 18 years and older living in Northern Ireland using the World Health Organization Composite International Diagnostic Interview. Analyses were implemented using the SUDAAN software system.

Results

12-month prevalence estimates were anxiety 14.6 %; mood 9.6 %; impulse control 3.4 %; substance 3.5 %; any disorder 23.1 %. Of the 12-month cases, 28.8 % were classified as serious; 33.4 % as moderate; and 37.8 % as mild. Females were more likely to have anxiety and mood disorders (p < 0.05) while males were more likely to have impulse-control and substance disorders. Just 40 % of individuals with any 12-month DSM-IV disorder received treatment in the previous 12 months. 78.6 % of those with a mental disorder who sought treatment received minimally adequate treatment.

Conclusions

12-month DSM-IV disorders are highly prevalent in Northern Ireland. A large proportion of those with mental health problems did not seek treatment. Further research is required to investigate the reasons behind low levels of treatment contact.     

Callous–unemotional traits as a cross-disorders construct

Purpose

Callous–unemotional (CU) traits are currently viewed as the defining signs and symptoms of juvenile psychopathy. It is unclear, however, whether CU traits have validity only in the context of conduct disorder (CD) as proposed by Frick and Moffitt (A proposal to the DSM-V childhood disorders and the ADHD and disruptive behavior disorders work groups to include a specifier to the diagnosis of conduct disorder based on the presence of callous–unemotional traits, American Psychiatric Association, Washington, DC, 2010), or also outside CD, either in combination with other forms of psychopathology or as a stand-alone construct.

Methods

The current review systematically studied the existent literature on CU traits in juveniles to examine their validity inside and outside CD according to the framework regarding the validity of a psychiatric diagnosis provided by Robins and Guze (Am J Psychiatry 126:983–987, 1970).

Results

Inside youth with conduct problems, and CD specifically, it seems that CU traits meet the Robins and Guze criteria. As many of the reviewed studies included youth with ODD and ADHD as well, there are indications the same might be true for ODD and ADHD, although probably to a lesser extent. In other disorders, CU traits may be present as well, but their role is not firmly established. As stand-alone construct, data are lacking or are scarce on all of the above-mentioned criteria.

Conclusions

CU traits are a useful specifier in CD, and possibly also in disruptive behaviour disorders (DBDs) more generally. High CU traits outside DBDs exist but it is as yet unknown if there is a clinical need for defining CU traits as a stand-alone construct.     

The Predictors of Parent Reported Behaviors Related to Olfactory Information Processing in Children with ADHD

Objective

Attention deficit hyperactivity disorder (ADHD) is a heterogeneous disorder with contradictory findings about smell detection function. It is not clear if the parent perceived behavior related to olfactory function is associated with age, gender, severity of ADHD, and cooccurring symptoms of anxiety and oppositional behavior in children with ADHD.

Methods

Participants were a clinical sample of 104 children and adolescents with ADHD using DSM-IV diagnostic criteria by a semi-structured interview. Parent perceived behavior related to olfactory processing function was assessed trough a questionnaire. The parent reported Olfactory Functioning Checklist was used to evaluate "seeking behavior and over-responsiveness to smell (SSBO)" and "smell detection ability (SDA)".

Results

ADHD and separation anxiety symptoms count (severity) predicted the SDA scale score. None of the variables of gender, age, ADHD subtypes, co-morbidity with oppositional defiant disorder (ODD), and symptom count of ODD predicted SSBO and SDA scales'' scores.

Conclusion

Parent reported behavior related to olfactory detection impairment increased with higher ADHD and anxiety severity. It is independent of age and gender.     

Prevalence of child and adolescent psychiatric disorders in Santiago, Chile: a community epidemiological study

Purpose

To determine the prevalence of DSM-IV psychiatric disorders in a representative sample of children and adolescents living in Santiago, Chile, as part of a national sample.

Method

Subjects aged 4–18 were selected using a stratified multistage design. First, ten municipalities/comunas of Santiago were selected; then the blocks, homes, and child or adolescent to be interviewed were chosen. Psychology graduate students administered the Spanish-language, computer-assisted version of DISC-IV that estimated DSM-IV 12-month prevalence.

Results

A total of 792 children and adolescents were evaluated, with a participation rate of 76.7%. The most stringent impairment DSM-IV DISC algorithm for psychiatric disorders revealed a prevalence of 25.4% (20.7% for boys and 30.3% for girls). The majority of the diagnoses corresponded to anxiety and affective disorders. Prevalence was higher in children aged 4–11 (31.9%) than in adolescents aged 12–18 (18.2%). This difference was mainly accounted for by disruptive disorders in the younger age group. Anxiety disorders had the highest prevalence, although impairment was low. In contrast, most children and adolescents with affective disorders were impaired.

Conclusions

In Santiago, the prevalence of psychiatric disorders in children and adolescents was high. This study helps raise awareness of child and adolescent mental health issues in Spanish-speaking Latin America and serves as a basis for improving mental health services.     

Prevalence of neurasthenia, comorbidity, and association with impairment among a nationally representative sample of US adults

Purpose

There are no current psychiatric epidemiological studies examining prevalence estimates of neurasthenia across different racial and ethnic groups in the US. This study compares prevalence rates of International Classification of Diseases (ICD-10) lifetime and 12-month neurasthenia across racial/ethnic groups in the US (Asians, African Americans, Latinos, and non-Latino Whites) and by levels of acculturation. We examine comorbidity of neurasthenia with DSM-IV psychiatric disorders and the association between neurasthenia and impairment.

Methods

We used a pooled sample (N?=?10, 118) from two nationally representative household surveys of adults ages 18?years and older: the National Comorbidity Survey-Replication (NCS-R) and the National Latino and Asian American Study (NLAAS).

Results

Among the total sample, the adjusted prevalence rates of lifetime and 12-month neurasthenia with exclusionary criteria were 2.22 and 1.19%. The adjusted prevalence rates for lifetime and 12-month neurasthenia without exclusionary criteria were 4.89 and 2.80%. There were significant racial/ethnic group differences in prevalence for both lifetime and past-year neurasthenia, with Asians reporting significantly lower prevalence of neurasthenia than their non-Latino White counterparts. Less acculturated individuals were at a decreased risk for lifetime and past-year neurasthenia. Lifetime neurasthenia was associated with increased odds of meeting lifetime criteria for any depressive, any anxiety, and any substance use disorder. Respondents with lifetime or past-year neurasthenia had significantly greater levels of impairment compared to those without neurasthenia.

Conclusion

Neurasthenia is a prevalent condition deserving further research attention given its comorbidity with other psychiatric disorders and its association with functional impairment.     

Comorbid anxiety and depression in school-aged children with attention deficit hyperactivity disorder (ADHD) and selfreported symptoms of ADHD,anxiety, and depression among parents of school-aged children with and without ADHD

Background

Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder in children that can extend into adulthood and that is often associated with a variety of comorbid psychiatric disorders.

Aim

Assess the comorbidity of ADHD with anxiety disorders and depressive disorders in school-aged children, and the relationship of the severity of ADHD, anxiety, and depressive symptoms in children who have ADHD with the severity of the corresponding symptoms in their parents.

Methods

A two-stage screening process identified children 7-10 years of age with and without ADHD treated at the Xin Hua Hospital in Shanghai. ADHD and other DSM-IV diagnoses were determined by a senior clinician using the Schedule for Affective Disorder and Schizophrenia for School-Aged Children (K-SADS-PL). One parent for each enrolled child completed three self-report scales: the ADHD Adult Self Report Scale (ASRS), the State-Trait Anxiety Inventory (STAI), and the Beck Depression Inventory (BDI). In total 135 children with ADHD and 65 control group children without ADHD were enrolled; parents for 94 of the children with ADHD and 63 of the children without ADHD completed the parental assessment scales.

Results

Among the 135 children with ADHD, 27% had a comorbid anxiety disorder, 18% had a comorbid depressive disorder, and another 15% had both comorbid anxiety and depressive disorders. Parents of children with ADHD self-reported more severe ADHD inattention symptoms than parents of children without ADHD and were more likely to meet criteria for adult ADHD. Mothers (but not fathers) of children with ADHD had significantly more severe trait anxiety and depressive symptoms than mothers of children without ADHD. Among children with ADHD, the severity of ADHD symptoms was not significantly correlated with the severity of ADHD symptoms in parents, but depressive symptoms and anxiety symptoms in the children were significantly correlated with the corresponding symptoms in the parents.

Conclusion

School-aged children with ADHD commonly suffer from comorbid anxiety and depressive disorders, and the severity of these symptoms parallels the level of anxiety and depressive symptoms in their parents. Self-reported symptoms of ADHD are significantly more common in parents of children with ADHD than in parents of children without ADHD. Longitudinal studies are needed to disentangle the genetic, biological, and social factors responsible for these complex inter-relationships.     

A card game for the treatment of delusional ideas: A naturalistic pilot trial

Background

Semi-structural clinical interviews are very important in the area of mental health research and services. There were no studies of the reliability and validity of the Farsi (Persian) version of Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL) in Iran. This study compares the results of face-to-face, semi-structural interview and clinical interview by a child and adolescent psychiatrist.

Method

Subjects were 109 children and adolescents recruited to the child and adolescent psychiatry outpatient clinic of Hafez Hospital. Order of interview (in-psychiatrist or the semi-structural interview) was determined using random assignment within a counterbalanced framework. After, translation and back translation of K-SADS-PL, the Farsi version of K-SADS-PL was provided and used in the study. The interviewer was unaware of the child and adolescent psychiatrist diagnosis at the time of making the interview. Consensual validity, test-retest and inter-rater reliability, sensitivity, specifity, positive and negative predictive validity for the disorders were studied.

Results

Consensual validity of all of the psychiatric disorders was good to excellent. It was highest for panic disorder, conduct disorder, and simple phobia. Consensual validity of anorexia nervosa was 0.49. There was sufficient validity and test-retest and inter-rater reliability and good to excellent sensitivity and specifity and positive and negative predictive validity for nearly all of the disorders. Test-retest reliabilities of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and tic disorder were 0.81, 0.67, and 0.56; respectively. Inter-rater reliabilities of ADHD, and ODD were 0.69 and 0.69. Tic disorder, post traumatic disorder, panic disorder, and ADHD had the highest positive predictive validities.

Conclusion

The Farsi version of K-SADS-PL is a valid and reliable interview instrument for use in assessing and diagnosising child and adolescent psychiatric disorders.     

The discriminative capacity of CBCL/1½-5-DSM5 scales to identify disruptive and internalizing disorders in preschool children

This paper studies the discriminative capacity of CBCL/1½-5 (Manual for the ASEBA Preschool-Age Forms & Profiles, University of Vermont, Research Center for Children, Youth, & Families, Burlington, 2000) DSM5 scales attention deficit and hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), anxiety and depressive problems for detecting the presence of DSM5 (DSM5 diagnostic and statistical manual of mental disorders, APA, Arlington, 2013) disorders, ADHD, ODD, Anxiety and Mood disorders, assessed through diagnostic interview, in children aged 3–5. Additionally, we compare the clinical utility of the CBCL/1½-5-DSM5 scales with respect to analogous CBCL/1½-5 syndrome scales. A large community sample of 616 preschool children was longitudinally assessed for the stated age group. Statistical analysis was based on ROC procedures and binary logistic regressions. ADHD and ODD CBCL/1½-5-DSM5 scales achieved good discriminative ability to identify ADHD and ODD interview’s diagnoses, at any age. CBCL/1½-5-DSM5 Anxiety scale discriminative capacity was fair for unspecific anxiety disorders in all age groups. CBCL/1½-5-DSM5 depressive problems’ scale showed the poorest discriminative capacity for mood disorders (including depressive episode with insufficient symptoms), oscillating into the poor-to-fair range. As a whole, DSM5-oriented scales generally did not provide evidence better for discriminative capacity than syndrome scales in identifying DSM5 diagnoses. CBCL/1½-5-DSM5 scales discriminate externalizing disorders better than internalizing disorders for ages 3–5. Scores on the ADHD and ODD CBCL/1½-5-DSM5 scales can be used to screen for DSM5 ADHD and ODD disorders in general populations of preschool children.     

Lifetime prevalence and age-of-onset of mental disorders in adults from the Argentinean Study of Mental Health Epidemiology

Purpose

Although the Global Burden of Disease Study estimated that depressive disorders and anxiety disorders are the second and fifth leading causes of disability in Argentina, these estimates were based on imputations rather than epidemiological data. The policy implications of these results for the necessary expansion of mental health services in Argentina are sufficiently great that more direct estimates of the population burdens of common mental disorders are needed. Therefore, the purpose is to present the first results regarding lifetime prevalence, projected lifetime risk up to age 75, age-of-onset, cohort effects and socio-demographic correlates of DSM-IV mental disorders among adults (18+) from the general population of urban areas of Argentina.

Method

A multistage clustered area probability household survey was administered to 3927 individuals using the World Mental Health Composite International Diagnostic Interview.

Results

Lifetime prevalence of any disorder was 29.1% and projected lifetime risk at age 75 was 37.1%. Median age-of-onset of any disorder was 20 years of age. Disorders with highest lifetime prevalence were major depressive disorder (8.7%), alcohol abuse (8.1%), and specific phobia (6.8%). Anxiety disorders were the most prevalent group of disorder (16.4%) followed by mood (12.3%), substance (10.4%), and disruptive behavior disorders (2.5%). Women had greater odds of anxiety and mood disorders; men had greater odds of substance disorders. Age-at-interview was inversely associated with lifetime risk of any disorder.

Discussion

The results provide direct evidence for high lifetime societal burdens of common mental disorders in Argentina due to a combination of high prevalence and early age-of-onset.

     

Mental disorders in primary care in Israel: prevalence and risk factors

Objective

Psychiatric morbidity is common among patients in primary care services and leads to disability and increased use of medical services. Comparison of primary care and community prevalence data is of interest in relation to the health services planning for mental disorders. The aim of the present study was to measure prevalence of mental disorders in six primary care clinics in Israel and to assess risk factors for these disorders.

Method

Prevalence of mental disorders was measured in a sample of 2,948 primary care consecutive attendees, using two-stage stratified sampling with the General Health Questionnaire 12 (GHQ-12) and the Composite International Diagnostic Interview (CIDI).

Results

A high rate (46.3 %) of current mental disorders was found, with rates of current depressive episode, generalized anxiety disorder, somatization disorder, and neurasthenia being relatively high in comparison with rates in other countries. Low education was a risk factor for all categories of disorders, unemployment a risk factor for depressive disorders, and parenthood was protective for most categories of disorders.

Conclusions

High rates of mental disorders were found in this Israeli primary care sample as compared to other countries, while in the community the rates were midrange as compared to other countries, pointing to a relatively higher use of primary care services by patients with mental disorders in Israel than in other countries.     

Mental and substance use disorders from early adolescence to young adulthood among indigenous young people: final diagnostic results from an 8-year panel study

Objective

Our objective was to investigate change in prevalence rates for mental and substance abuse disorders between early adolescence and young adulthood in a cohort of indigenous adolescents who participated in an 8-year panel study.

Method

The data are from a lagged, sequential study of 671 indigenous adolescents (Wave 1) from a single culture in the Northern Midwest USA and Canada. At Wave 1 (mean age 11.3 years, Wave 4 (mean age 14.3 years), Wave 6 (mean age 16.2 years), and at Wave 8 (mean age 18.3 years) the tribally enrolled adolescents completed a computer-assisted personal interview that included DISC-R assessment for 11 diagnoses. Our yearly retention rates by diagnostic wave were: Wave 2, 94.7 %; Wave 4, 87.7 %; Wave 6, 88.0 %; Wave 8, 78.5 %.

Results

The findings show a dramatic increase in lifetime prevalence rates for substance use disorders. By young adulthood, over half had met criteria of substance abuse or dependence disorder. Also at young adulthood, 58.2 % had met lifetime criteria of a single substance use or mental disorder and 37.2 % for two or more substance use or mental disorders. The results are compared to other indigenous diagnostic studies and to the general population.

Conclusions

A mental health crisis exists within the indigenous populations that participated in this study. Innovations within current mental health service systems are needed to address the unmet demand of adolescents and families.     

Sociodemographic and psychopathologic predictors of first incidence of DSM-IV substance use, mood and anxiety disorders: results from the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions

The objective of this study was to present nationally representative findings on sociodemographic and psychopathologic predictors of first incidence of Diagnostic and Statistical Manual of Mental Disorders, 4th edn (DSM-IV) substance, mood and anxiety disorders using the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions. One-year incidence rates of DSM-IV substance, mood and anxiety disorders were highest for alcohol abuse (1.02), alcohol dependence (1.70), major depressive disorder (MDD; 1.51) and generalized anxiety disorder (GAD; 1.12). Incidence rates were significantly greater (P<0.01) among men for substance use disorders and greater among women for mood and anxiety disorders except bipolar disorders and social phobia. Age was inversely related to all disorders. Black individuals were at decreased risk of incident alcohol abuse and Hispanic individuals were at decreased risk of GAD. Anxiety disorders at baseline more often predicted incidence of other anxiety disorders than mood disorders. Reciprocal temporal relationships were found between alcohol abuse and dependence, MDD and GAD, and GAD and panic disorder. Borderline and schizotypal personality disorders predicted most incident disorders. Incidence rates of substance, mood and anxiety disorders were comparable to or greater than rates of lung cancer, stroke and cardiovascular disease. The greater incidence of all disorders in the youngest cohort underscores the need for increased vigilance in identifying and treating these disorders among young adults. Strong common factors and unique factors appear to underlie associations between alcohol abuse and dependence, MDD and GAD, and GAD and panic disorder. The major results of this study are discussed with regard to prevention and treatment implications.     

Patterns of psychiatric comorbidity with attention-deficit/hyperactivity disorder

Attention deficit/hyperactivity disorder (ADHD) is frequently comorbid with a variety of psychiatric disorders. These disorders include oppositional defiant (ODD) and conduct disorders (CD), and affective, anxiety, and learning disorders. Studies which have examined the comorbidity of these disorders with ADHD are reviewed. ADHD and ADHD with CD seem to be distinct subtypes; children with ADHD/CD are at higher risk of antisocial personality as adults. Coexisting anxiety may attenuate impulsivity in ADHD. Studies examining stimulant response in children with ADHD/anxiety have recently yielded conflicting results. Anxiety and ADHD seem to be inherited independently. The prevalence of major depressive disorder (MDD) and bipolar disorder among children with ADHD is controversial, but there clearly exists a subgroup of severely emotionally labile children with ADHD who present serious management issues for the clinician. About 20% to 25% of children with ADHD meet criteria for a learning disorder (LD), but LD seems to be independent of ADHD.     

Prevalence of mental health disorders among low-income African American adolescents

Purpose

Data on the prevalence of mental health disorders for low-income, urban African American adolescents are scarce. This study presents data about the burden of mental disorders for this understudied population.

Methods

Mental disorders were assessed using the Diagnostic Interview Schedule for Children (C-DISC), Youth Self-Report (YSR), and Child Behavior Checklist (CBCL) among a sample of adolescents and their caregivers from very impoverished neighborhoods in a Southern city.

Results

Based on the C-DISC, 3.8, 5.1 and 7.7 % of adolescents met diagnostic criteria for major depression, post-traumatic stress disorder, and conduct disorder, respectively. There were significant differences among some of the mental health disorders based on adolescent and caregiver characteristics such as sex, school status, caregiver work status, and income level. We found a low prevalence of alcohol, marijuana, and substance abuse and dependence disorders.

Conclusions

Information about the prevalence of mental health disorders in specific communities and populations can assist in addressing unmet needs, planning for services and treatment, and reducing health disparities.
