Prevalence and correlates of antisocial behaviors among three ethnic groups.

Using data from the MECA Study, this report examines the prevalence of Conduct Disorder (CD), Oppositional Defiant Disorder (ODD), and various levels of antisocial behavior and their correlates among three ethnic groups: Hispanics, subdivided into Island Puerto Ricans and Mainland Hispanics; African Americans; and Mainland Non-Hispanic, Non-African Americans. Correlates considered include stressful life events, birth defects, low birth weight, learning difficulties, teen mothers, family environment, marital adjustment, social competence, parental monitoring, and family relationships. Logistic regression was used to determine the association of outcomes with individual correlates and of interaction terms with ethnicity. Differences between adjusted rates and observed rates of disorders and levels of antisocial behaviors are compared to estimate the extent to which each correlate explains the group differences in rates. Island Puerto Ricans had a lower prevalence of CD, ODD, and various levels of antisocial behavior than mainland Hispanics, African Americans, and non-Hispanic Whites. The lower prevalence appears to be associated with differences in the extent to which a number of these correlates are found on the island, the most salient being better family relations between the target children and their parents and siblings.

Risk behavior in a community sample of children and adolescents.

OBJECTIVES: First, to investigate whether there is covariation between risk behaviors, including suicidality, in a community probability sample of children and adolescents; and second, to investigate whether risk behavior is associated with selected potential correlates. METHOD: A sample of 9- to 17-year-old youths (N = 1,285) and their caretakers were interviewed in the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. The risk behaviors were marijuana smoking, alcohol use, intercourse, fighting, cigarette smoking, and suicidal ideation/attempts. Relationships between the risk behaviors were described using odds ratios. Linear regression analyses of an index of risk behavior on the selected potential correlates of risk behavior were conducted. RESULTS: There were significant relationships between all pairs of risk behaviors. The score on the index of risk behavior was associated with stressors, lack of resources, family psychiatric disorder, psychopathology, and functional impairment. CONCLUSIONS: Clinicians should be alerted to the possibility of risk behaviors, especially in children and adolescents engaging in other risk behaviors and those with inadequate resources, stressors, functional impairment, or psychopathology.

Are stimulants overprescribed? Treatment of ADHD in four U.S. communities.

OBJECTIVE: To address rising concerns about the possible overdiagnosis of attention-deficit hyperactivity disorder (ADHD) and overtreatment with stimulants. To date, almost no studies have examined ADHD in unbiased community-based studies, ascertaining both the prevalence of the diagnosis within nonreferred populations and the extent to which various treatments (i.e., stimulant medication, mental health treatments, and educational interventions) are used. METHOD: As a part of the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study, the authors examined epidemiological survey data obtained from 1,285 children and their parents across 4 U.S. communities. Analyses examined the frequency of children's ADHD diagnosis, the extent to which medications were prescribed, as well as the provision of other services (e.g., psychosocial treatments, school-based educational interventions). RESULTS: Findings indicated that 5.1% of children met full DSM-III-RADHD criteria across the pooled sample. Only 12.5% of children meeting ADHD criteria had been treated with stimulants during the previous 12 months. Some children who had been prescribed stimulants did not meet full ADHD diagnostic criteria, but these children manifested high levels of ADHD symptoms, suggesting that the medication had been appropriately prescribed. Children with ADHD were generally more likely to receive mental health counseling and/or school-based interventions than medication. CONCLUSIONS: Medication treatments are often not used in treating ADHD children identified in the community, suggesting the need for better education of parents, physicians, and mental health professionals about the effectiveness of these treatments. On the basis of these data it cannot be concluded that substantial "overtreatment" with stimulants is occurring across communities in general.

Validity of DSM-IV subtypes of conduct disorder based on age of onset.

OBJECTIVE: To present data from the DSM-IV field trials that led to the distinction between subtypes of conduct disorder (CD) that emerge in childhood or adolescence. In addition, data from a household sample were used to attempt to cross-validate these findings. METHOD: Differences between youths who met criteria for the two subtypes of CD were examined in the field trials sample of 440 youths aged 4 through 17 years and in a household sample of 1,285 youths aged 9 through 17 years. RESULTS: In both samples, there was a steep decline in aggression occurring around an age of onset of 10 years, but the number of nonaggressive behaviors was unrelated to the age of onset of CD. In the field trials sample, youths who met criteria for the adolescent-onset type were more likely to be girls, less likely to meet criteria for oppositional defiant disorder, and less likely to have a family history of antisocial behavior than the childhood-onset type, but these latter findings were not confirmed in the household sample. CONCLUSIONS: The DSM-IV approach to subtyping CD distinguishes subgroups that differ markedly in level of physical aggression. The advantages of a developmental approach to subtyping are discussed.

Psychosocial characteristics of physically abused children and adolescents.

OBJECTIVE: To examine the association between physical abuse and selected psychosocial measures in a community-based probability sample of children and adolescents. METHOD: A sample of 9- through 17-year-olds (N = 665) and their caretakers in New York State and Puerto Rico were interviewed in the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. Assessments included the Columbia Impairment Scale, the Instrumental and Social Competence Scale, the Diagnostic Interview Schedule for Children, the Peabody Picture Vocabulary Test, and questions regarding physical abuse. Regression analyses were conducted controlling for family income, family psychiatric history, perinatal problems, physical health, and sexual abuse. RESULTS: A history of physical abuse was reported in 172 (25.9%) of the sample. It was significantly associated with global impairment, poor social competence, major depression, conduct disorder, oppositional defiant disorder, agoraphobia, overanxious disorder, and generalized anxiety disorder but not with suicidality, school grades, or receptive language ability. CONCLUSION: A community probability sample of children and adolescents demonstrated significant associations between physical abuse and psychopathology, after controlling for potential confounders. This supports comprehensive screening for psychopathology among physically abused children and for physical abuse among those with psychopathology. Interventions aimed at improving social competence may be indicated.

Patterns of diagnostic comorbidity in a community sample of children aged 9 through 16 years.

Secondary analyses of the data from the Puerto Rico Child Psychiatry Epidemiologic Study were done to provide information on the comorbidity of four major diagnostic domains (attention deficit disorders, conduct/oppositional disorders, depression and anxiety disorders). A high level of comorbidity was found among these four domains of child and adolescent psychopathology. In general the patterns of comorbidity were not affected by whether the data was put together by a clinician or by means of a computer algorithm scoring a structured interview. The patterns were not affected in any major way by who the informants were in the diagnostic process. Minor differences were found in certain comorbidity patterns depending on the sex and age of the subjects. Comorbidity was associated with level of impairment and to service utilization.

Mental health status among Puerto Ricans, Mexican Americans, and non-Hispanic whites.

Compared mental health characteristics of island Puerto Ricans to three groups from the Los Angeles Epidemiologic Catchment Area Study: Mexican American immigrants, U.S.-born Mexican Americans, and Non-Hispanic whites. The Diagnostic Interview Schedule was used to obtain both diagnostic and symptom scale information about affective disorders, alcohol abuse/dependence, somatization, phobic disorder, and psychotic disorder. Mexican American immigrants had the fewest mental health problems of all groups. Puerto Ricans had more somatization disorder, but less affective and alcohol disorders than U.S.-born Mexican Americans or non-Hispanic whites. Results are considered in the light of selection factors, relative disadvantage of groups and methodological problems.

Are attentional-hyperactivity deficits unidimensional or multidimensional syndromes? Empirical findings from a community survey.

Factor analysis on teacher ratings of symptoms in a probability community sample of children aged 6 to 16 years (N = 614) yielded two factors: Inattention and Hyperactivity-Impulsivity. Subsequent cluster analyses on the scores of factorially derived scales for a subsample of 170 children with a diagnosis of attention deficit disorder with (ADDH) and without hyperactivity (ADDWO), or normals, resulted in five clusters that accounted for 88% of the variance. The existence of these clusters was confirmed using external validating criteria. The data support a bidimensional conceptualization of attention deficit disorder with hyperactivity, one dimension consisting of symptoms of inattention and another of symptoms of hyperactivity-impulsivity. The data also suggests that a condition very similar to the DSM-III-R description of undifferentiated attention-deficit disorder also exists as a distinct entity.

Aggregating data from multiple informants in child psychiatry epidemiological research.

One of the issues confronting the field of child psychiatric epidemiology is devising ways to aggregate discrepant reports from multiple informants obtained in structured diagnostic assessments of children and adolescents. The present report uses data from an epidemiological community survey to attempt to address this issue. The results obtained through statistical procedures designed to identify the "optimal" informant for specific symptomatic criteria and diagnoses do not seem to offer a clear-cut advantage over a simple combinatorial rule that identifies symptomatic criteria as positive when they are acknowledged as positive by either parent or child informants.

Screening for childhood psychopathology in the community using the Child Behavior Checklist.

One of the uses of the Child Behavior Checklist is as a screening instrument for childhood psychopathology in two-phase designs. The present report involves a two-phase epidemiological survey conducted in Puerto Rico in which the CBCL was used as a screening instrument during the first stage, and children were evaluated clinically during the second stage. The data indicate that in using the CBCL for screening for psychopathology in children, parent information is most informative, particularly for children in the adolescent age group. Nevertheless, the data also reinforce the need to obtain teacher information with the Teacher Report Form to enhance screening sensitivity. In this population, the data obtained with the Youth Self-Report were found to be of limited usefulness for screening purposes.

Impairment in the epidemiological measurement of childhood psychopathology in the community.

The desirability of incorporating a measure of impairment to the categorization of childhood psychopathology in the community is examined. The use of the Children's Global Assessment Scale (CGAS) for this purpose is recommended. The choice of 61 (definite case) and 71 (probable case) as cutpoints on the Children's Global Assessment Scale is supported empirically by the data on service utilization, parental perceived need, and behavior problem scores obtained in the Puerto Rico Child Psychiatry Epidemiological Study.

Epidemiological comparisons of Puerto Rican and U.S. mainland children: parent, teacher, and self-reports.

U.S. mainland and Puerto Rican nonreferred samples were compared via the Child Behavior Checklist (ages 4 to 16), Teacher's Report Form (ages 6 to 16), and Youth Self-Report (ages 12 to 16). Problem scores were significantly higher in parent and teacher ratings of Puerto Rican than mainland subjects, but were significantly lower in self-ratings by Puerto Rican adolescents. Adolescents in both cultures reported significantly more problems than their parents or teachers did. Most of the significant cross-cultural differences in parent, teacher, and self-ratings of competencies showed more favorable scores for the mainland subjects. High referral rates, a high prevalence of DSM diagnoses, and low scores on the Children's Global Assessment Scale are consistent with the high problem rates reported by Puerto Rican parents and teachers but not with the lower rates reported by adolescents. Different clinical cutoffs may be needed for all assessments in the mainland versus Puerto Rico.

Risk factors for maladjustment in Puerto Rican children.

Data are presented on risk factors for childhood psychopathology derived from a study of an island-wide probability sample of children in Puerto Rico aged 4 through 16 years. Analyses estimated the effects of 12 demographic, health, and family variables on the probability of being a "case," using two different operational definitions of caseness, as well as on the probability of receiving the diagnoses of oppositional disorder, attention deficit disorder, separation anxiety, depression, functional enuresis, and adjustment disorder. When compared to other findings, the results from these analyses indicate that the relationship between maladjustment and the risk factors evaluated does not appear to be culturally specific.

Estimates of the prevalence of childhood maladjustment in a community survey in Puerto Rico. The use of combined measures.

A two-stage epidemiologic survey was carried out on a probability sample of the population aged 4 through 16 years in Puerto Rico. The survey used the Child Behavior Checklist as a screening instrument, and prevalence rates were estimated on the basis of clinical diagnoses and other measures provided by child psychiatrists during the second stage. Maladjustment was operationally defined through the use of combined measures, including DSM-III diagnosis and a scale of functional impairment. Data were provided on the demographic correlates of maladjustment and on the comorbidity of DSM-III diagnostic domains. The prevalence rates obtained vis-à-vis the availability of mental health services on the island reflected a major public health problem.

Use of the Mini-mental State Examination in a probability sample of a Hispanic population.

The Spanish DIS was applied to a community probability sample in an island-wide survey of the prevalence of psychiatric disorders in Puerto Rico. The prevalence of "severe cognitive impairment" as measured by the DIS Mini-mental State Examination (DIS/MMSE) is significantly higher than that reported in similar studies in US communities. The total sample (N = 1532) was used to study the impact of demographic variables and other psychiatric diagnoses on DIS/MMSE scores. Educational level was by far the strongest predictor of total scores as well as of scores on individual items. Issues are discussed and recommendations are made related to the use of this test in Hispanic populations of low educational level.

The Spanish Diagnostic Interview Schedule. Reliability and concordance with clinical diagnoses in Puerto Rico.

A Spanish translation of the Diagnostic Interview Schedule (DIS) was assessed using samples of Puerto Rican patients and community subjects from the San Juan area. Concordance between DIS results from psychiatrists' interviews and from laypersons' interviews was similar to results with the DIS in mainland samples. Comparisons of laypersons' DIS results with psychiatrists' clinical diagnoses yielded generally poorer agreement. Levels of agreement improved when diagnoses were clustered into higher-rank categories. These results raise cultural issues related to the use of the DIS in Puerto Rico.

The prevalence of specific psychiatric disorders in Puerto Rico.

An epidemiologic survey of the lifetime and six-month prevalence rates of several psychiatric disorders was conducted in Puerto Rico. This study, carried out in 1984, applied selected schedules of a Spanish translation of the Diagnostic Interview Schedule to a stratified, island-wide probability sample of the population. With few exceptions, prevalence rates in this study were similar to those obtained in the US communities studied in the Epidemiologic Catchment Area program. The demographic correlates of the disorders are reviewed, and differences between the results of this study and those of previous studies suggesting a higher rate of mental disorder among Puerto Rican populations are discussed.

The cultural dichotomy of colonial people.

We have presented a justification for the application of some of the principles of individual psychic development to the understanding of societal development. The interplay between the various systems of organization provides a circular and reciprocal interaction between the individual and the broader organizational levels of which he is a part. We have noted how individuals contribute to the characteristics of these organizational levels, as they contribute to his own. An illustration of this interplay has been provided by describing the impact of a societal condition such as colonialism on the colonized individual, as well as its force in shaping the character of the collectivity. Its effect on individual parameters of self-definition and self-esteem has been noted, and its possible relevance to psychotherapeutic processes pointed out.
