Mental Health Service Use in the Community and Schools: Results from the Four-Community MECA Study

ABSTRACT Objective To describe the use of mental health and substance abuse services by children and adolescents as reported from the four community sites included in the NIMH Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. Method As part of the MECA survey, questions were developed to identify children and adolescents utilizing mental health and substance abuse services. Youths aged 9 through 17 years and a parent/ caretaker were interviewed. Because the investigators had concerns about the capacities of the younger children in the study to describe their use of mental health services, more extensive questions were asked of parents than of youths. Results The procedures developed by the MECA project identified patterns of service use that varied in the four communities surveyed. Agreement between reports of parents and youths regarding the use of mental health and substance abuse services showed substantial Inconsistencies, similar to reports of psychiatric disorders. At three of the four sites, the majority of children meeting criteria for a psychiatric disorder and scoring 60 or less on the Childrens Global Assessment Scale reported some mental health–related service in the previous year, although at two of the sites fewer than 25% of these youths were seen in the mental health specialty sector. Conclusion Community surveys show great promise for monitoring the need for mental health and substance abuse services and for identifying patterns of use.

Depressive and Disruptive Disorders and Mental Health Service Utilization in Children and Adolescents

OBJECTIVE To examine the relationship of depressive and disruptive disorders with patterns of mental health services utilization in a community sample of children and adolescents. METHOD Data were from the NIMH Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. The sample consisted of 1,285 child (ages 9-17 years) and parent/guardian pairs. Data included child psychopathology (assessed by the Diagnostic Interview Schedule for Children), impairment, child need and use of mental health services, and family socioeconomic status. RESULTS After adjusting for potential confounding factors, disruptive disorder was significantly associated with childrens use of mental health services, but depressive disorder was not. For school-based services, no difference was found between the 2 types of disorders. Parents perceived greater need for mental health services for children with disruptive disorders than for those with depression. Conversely, depression was more related to childrens perception of mental health service need than was disruptive disorder. CONCLUSIONS The findings highlight the need for more effective ways to identify and refer depressed children to mental health professionals, the importance of improving school-based services to meet childrens needs, and the necessity to better educate parents and teachers regarding the identification of psychiatric disorders, especially depression.

Clinicopathological significance of psychotic experiences in non-psychotic young people: evidence from four population-based studies

BACKGROUND Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence. AIMS To investigate the relationship between psychotic symptoms and non-psychotic psychopathology in community samples of adolescents in terms of prevalence, co-occurring disorders, comorbid (multiple) psychopathology and variation across early v. middle adolescence. METHOD Data from four population studies were used: two early adolescence studies (ages 11-13 years) and two mid-adolescence studies (ages 13-16 years). Studies 1 and 2 involved school-based surveys of 2243 children aged 11-16 years for psychotic symptoms and for emotional and behavioural symptoms of psychopathology. Studies 3 and 4 involved in-depth diagnostic interview assessments of psychotic symptoms and lifetime psychiatric disorders in community samples of 423 children aged 11-15 years. RESULTS Younger adolescents had a higher prevalence (21-23%) of psychotic symptoms than older adolescents (7%). In both age groups the majority of adolescents who reported psychotic symptoms had at least one diagnosable non-psychotic psychiatric disorder, although associations with psychopathology increased with age: nearly 80% of the mid-adolescence sample who reported psychotic symptoms had at least one diagnosis, compared with 57% of the early adolescence sample. Adolescents who reported psychotic symptoms were at particularly high risk of having multiple co-occurring diagnoses. CONCLUSIONS Psychotic symptoms are important risk markers for a wide range of non-psychotic psychopathological disorders, in particular for severe psychopathology characterised by multiple co-occurring diagnoses. These symptoms should be carefully assessed in all patients.

Adverse life events and resilience.

OBJECTIVE Adverse life events are well-documented risk factors of psychopathology and psychological dysfunction in children and adolescents. Youth with good adjustment despite high levels of adverse life events are considered resilient. This study identifies factors that characterize resilience. METHOD Household probability samples of youth aged 9 through 17 years at four sites were used. Main and interaction effects of 11 factors were examined to assess their impact on youth adjustment. RESULTS Children at risk because of higher levels of adverse life events exhibited a greater degree of resilience when they had a higher IQ, better family functioning, closer parental monitoring, more adults in the household, and higher educational aspiration. The interaction between maternal psychopathology and adversity was significant, and the interaction between IQ and adversity approached significance. CONCLUSION Resilient youth received more guidance and supervision by their parents and lived in higher-functioning families. Other adults in the family probably complemented the parents in providing guidance and support to the youth and in enhancing youth adjustment. Higher educational aspirations might have provided high-risk youth with a sense of direction and hope. Although IQ had no impact in youth at low risk, youth at high risk who had a higher IQ might have coped better.

Correlates of unmet need for mental health services by children and adolescents

BACKGROUND Little is known about the extent and correlates of unmet need for mental health services in community samples of children and adolescents. METHODS Data were obtained from the 1285 parent/youth pairs interviewed at four sites in the USA and Puerto Rico in the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. Unmet need was defined to exist if psychopathology and associated functional impairment were present but no mental health services had been received in the previous 6 months. RESULTS Of the total sample, 17.1% had unmet need. Adjusting for demographic variables, logistic regression analyses revealed that unmet need was significantly associated with: indicators of economic disadvantage, such as being on public assistance and not being covered by health insurance; opinions of the parents and children or adolescents that the latter had poor mental health; parental psychopathology; poor school grades; and parent-reported access barriers such as concern that the child would want to solve the problem unassisted, would refuse to attend mental health services, or would be hospitalized or taken away against the parents will. No youth-reported access barriers were significantly associated with unmet need. CONCLUSIONS The economic correlates of unmet need may attain increased importance in the light of current reform in health care financing in the USA. Access may be facilitated by increasing parental knowledge of mental health services and enabling children and adolescents to initiate contact with services independently of their families.

The Association between Pathological Internet Use and Comorbid Psychopathology: A Systematic Review

Background: Pathological Internet use (PIU) has been conceptualized as an impulse-control disorder that shares characteristics with behavioral addiction. Research has indicated a potential link between PIU and psychopathology; however, the significance of the correlation remains ambiguous. The primary objective of this systematic review was to identify and evaluate studies performed on the correlation between PIU and comorbid psychopathology; the secondary aims were to map the geographical distribution of studies, present a current synthesis of the evidence, and assess the quality of available research. Sampling and Methods: An electronic literature search was conducted using the following databases: MEDLINE, PsycARTICLES, PsychINFO, Global Health, and Web of Science. PIU and known synonyms were included in the search. Data were extracted based on PIU and psychopathology, including depression, anxiety, symptoms of attention deficit and hyperactivity disorder (ADHD), obsessive-compulsive symptoms, social phobia and hostility/aggression. Effect sizes for the correlations observed were identified from either the respective publication or calculated using Cohen’s d or R2. The potential effect of publication bias was assessed using a funnel plot model and evaluated by Egger’s test based on a linear regression. Results: The majority of research was conducted in Asia and comprised cross-sectional designs. Only one prospective study was identified. Twenty articles met the preset inclusion and exclusion criteria; 75% reported significant correlations of PIU with depression, 57% with anxiety, 100% with symptoms of ADHD, 60% with obsessive-compulsive symptoms, and 66% with hostility/aggression. No study reported associations between PIU and social phobia. The majority of studies reported a higher rate of PIU among males than females. The relative risks ranged from an OR of 1.02 to an OR of 11.66. The strongest correlations were observed between PIU and depression; the weakest was hostility/aggression. Conclusions: Depression and symptoms of ADHD appeared to have the most significant and consistent correlation with PIU. Associations were reported to be higher among males in all age groups. Limitations included heterogeneity in the definition and diagnosis of PIU. More studies with prospective designs in Western countries are critically needed.

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.

Childhood trauma and psychosis in a prospective cohort study: Cause, effect, and directionality

OBJECTIVE Using longitudinal and prospective measures, the authors assessed the relationship between childhood trauma and psychotic experiences, addressing the following questions: 1) Does exposure to trauma predict incident psychotic experiences? 2) Does cessation of trauma predict cessation of psychotic experiences? 3) What is the direction of the relationship between childhood trauma and psychotic experiences? METHOD This was a nationally representative prospective cohort study of 1,112 school-based adolescents 13-16 years of age, assessed at baseline and at 3-month and 12-month follow-ups for childhood trauma (physical assault and bullying) and psychotic experiences. RESULTS A bidirectional relationship was observed between childhood trauma and psychosis, with trauma predicting psychotic experiences over time and vice versa. However, even after accounting for this bidirectional relationship with a number of strict adjustments (only newly incident psychotic experiences occurring over the course of the study following exposure to traumatic experiences were examined), trauma was strongly predictive of psychotic experiences. A dose-response relationship was observed between severity of bullying and risk for psychotic experiences. Moreover, cessation of trauma predicted cessation of psychotic experiences, with the incidence of psychotic experiences decreasing significantly in individuals whose exposure to trauma ceased over the course of the study. CONCLUSIONS After a series of conservative adjustments, the authors found that exposure to childhood trauma predicted newly incident psychotic experiences. The study also provides the first direct evidence that cessation of traumatic experiences leads to a reduced incidence of psychotic experiences.

Measurement of risk for mental disorders and competence in a psychiatric epidemiologic community survey: the National Institute of Mental Health Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study.

Abstract This paper describes the implementation of the National Institute of Mental Health Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) studys goals of measuring risk factors and competence. The emphasis is on the development and testing of the measures. Relevant constructs for measurement of risk and competence in relation to psychopathology were selected and pilot tested prior to the field trials. A structured interview was developed and field tested using lay interviewers. Using the full sample from the field trials (n = 1285 caretaker-youth pairs), sample means, standard deviations, internal consistencies, parent-youth agreement, and associations with childhood disorder were computed. Descriptive statistics reveal a range of scores and means consistent with norming samples, when available. Internal consistencies were moderate to high. Parent-youth agreement on factual items was excellent and on scales was consistent with the literature. Several strong associations were found between risk factors and disorder, although most were related to disorder in general and not specific to a diagnostic category. This instrument provides a means of obtaining data that will be useful to researchers conducting epidemiologic and clinical studies designed to contribute to the understanding of mental disorders in children and adolescents, including nosology, risk factors, context, adaptive functioning, and treatment.

Adolescent subthreshold-depression and anxiety: psychopathology, functional impairment and increased suicide risk

BACKGROUND  Subthreshold-depression and anxiety have been associated with significant impairments in adults. This study investigates the characteristics of adolescent subthreshold-depression and anxiety with a focus on suicidality, using both categorical and dimensional diagnostic models. METHODS  Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, comprising 12,395 adolescents from 11 countries. Based on self-report, including Beck Depression Inventory-II (BDI-II), Zung Self-Rating Anxiety Scale (SAS), Strengths and Difficulties Questionnaire (SDQ) and Paykel Suicide Scale (PSS) were administered to students. Based on BDI-II, adolescents were divided into three groups: nondepressed, subthreshold-depressed and depressed; based on the SAS, they were divided into nonanxiety, subthreshold-anxiety and anxiety groups. Analyses of Covariance were conducted on SDQ scores to explore psychopathology of the defined groups. Logistic regression analyses were conducted to explore the relationships between functional impairments, suicidality and subthreshold and full syndromes. RESULTS  Thirty-two percent of the adolescents were subthreshold-anxious and 5.8% anxious, 29.2% subthreshold-depressed and 10.5% depressed, with high comorbidity. Mean scores of SDQ of subthreshold-depressed/anxious were significantly higher than the mean scores of the nondepressed/nonanxious groups and significantly lower than those of the depressed/anxious groups. Both subthreshold and threshold-anxiety and depression were related to functional impairment and suicidality. CONCLUSIONS Subthreshold-depression and subthreshold-anxiety are associated with an increased burden of disease and suicide risk. These results highlight the importance of early identification of adolescent subthreshold-depression and anxiety to minimize suicide. Incorporating these subthreshold disorders into a diagnosis could provide a bridge between categorical and dimensional diagnostic models.
