The Quebec Child Mental Health Survey (QCMHS) was conducted in 1992 on a representative sample of 2400 children and adolescents aged 6 to 14 years from throughout Quebec. Prevalences of nine Axis-I DSM-III-R (American Psychiatric Association, 1987) mental health disorders were calculated based on each informant (for 6-11-year-olds: child, parent, and teacher; for 12-14-year-olds: child and parent). Informant parallelism allows the classification of results of the demographic variables associated with disorders in the logistic regression models. This strategy applies to group variables (correlates of disorders) whereas informant agreement applies to individual diagnoses. Informant parallelism implies that results for two informants or more are in the same direction and significant. In the QCMHS, informant parallelism exists for disruptive disorders, i.e. in two ADHD regression models (child and parent) higher rates among boys and young children, and in three oppositional/conduct disorders regression models (child, parent, and teacher) higher rates among boys. No informant parallelism is observed in the logistic regression models for internalizing disorders, i.e. the patterns of association of demographic variables with anxiety and depressive disorders vary across informants. Urban-rural residence does not emerge as a significant variable in any of the logistic regression models. The overall 6-month prevalences reach 19.9% according to the parent and 15.8% according to the child. The implications of the results for policy makers and clinicians are discussed.

This paper presents a structured pictorial instrument, the Dominic questionnaire, to assess mental disorders in 6- to 11-year-old children. Ninety-nine drawings represent situations corresponding to DSM-III-R based ADHD, CD, ODD, MDD, SAD, OAD, and SPh. However, cognitive limitation of 6- to 11-year-old children do not allow for time-related measurement. The instrument takes 15–20 min to administer. Reliability and validity of the Dominic questionnaire were studied in Parent DISC-2 positive and negative outpatient and general population samples and against clinical judgement. The pictorial approach provides acceptable test-retest reliability and the instrument makes standardized assessment possible for children as young as 6 years of age.

Objectives: This study aimed to identify hospital resources by region, determine human resources by type of service and region, and describe how services generally operate in child psychiatry within the province of Quebec. Methods: Data collection took place from May to October 2001. We sent a semistructured questionnaire to all child psychiatry service heads. We collected human resource data and produced organizational charts based on the responses obtained. These charts were forwarded to each of the participating services for validation. We grouped Quebecs 18 social health regions into 3 categories: central (4 regions with 606 370 youths), adjoining (4 regions with 589 750 youths), and peripheral (10 regions with 368 635 youths). Results: The response rate was 100%. We identified 35 child psychiatry services: 13 in the central regions, 9 in the adjoining regions, and 13 in the peripheral regions. Overall, we identified 177 short-stay beds, 476 places in day or evening hospitals, and 113 places in day or evening centres. Most of these resources were located in the central regions. Quebec had 138.2 full-time equivalent (FTE) child psychiatrists (69.8% in the central regions) and 706 FTE professionals. At March 31, 2001, 4285 youths were waiting for services. Conclusions: We observed a shortage of child psychiatrists and professionals, regardless of the norm used. Adjoining and peripheral regions should have access to a minimal range of human and hospital resources in child psychiatry.

Objectives: The purpose of this study was twofold: 1) to determine whether publicly funded mental health services and resources available in 4 large regions in the province of Quebec were distributed according to the mental health needs of children aged 6 to 14 years and 2) to assess whether the variations in mental health services and resources across the 4 regions had changed over a 5-year period. Methods: Indicators of need according to the childs parent (presence of mental disorder, measure of adaptation, and perception of need for help) from an epidemiologic survey of 2400 noninstitutionalized children were compared with both in-school and community professional resources and with physician and hospital services in 1992–1993. Resource and service data were also collected for 1997–1998. Resource and service data came from professional colleges and government administrative databases. Results: No significant regional differences were found for need indicators, but there were large discrepancies in mental health resources and services in 1992–1993. Differences in professional resources were largest for special education teachers in the school system and for psychiatrists in the community. The regional differences in resources and services were as large in 1997–1998 as they were in 1992–1993. Conclusions: Despite universal health care in Quebec and a government mental health policy stressing equity of access, the available mental health resources for children aged 6 to 14 years are not distributed across regions according to needs. More evidence-based planning is required, specifically using epidemiologic survey data, to match resources to needs and to monitor changes over time.

Objective: To report psychometric data from preliminary studies of the Adolescent Dominic (AD), a pictorial screen for the most frequent Axis I youth mental disorders. Methods: We created 113 picture items based on DSM-III-R diagnostic criteria and assessed them for comprehension (sample 1, n = 114; sample 2, n = 40) and reliability (sample 3, n = 128) in a group of adolescents aged 12 to 16 years living in the community. We used the kappa statistic to estimate test–retest reliability of symptoms, criteria and diagnoses, and intraclass correlation coefficients (ICCs) for symptom and criterion scores. We assessed internal consistency of symptom scores with the alpha coefficient. Results: For symptoms, 54.4% of kappas were higher than 0.60, while only 2% were poor. ICCs for symptom scores yielded higher values (0.81 to 0.89) than for criterion scores (0.51 to 0.86). Internal consistency of symptom scores ranged from 0.52 to 0.83. Kappas for diagnoses ranged from 0.52 to 0.76. Conclusions: Symptom reliability compared favourably with data from other assessment interviews of youth mental disorders. Following these positive results, a computerized DSM-IV version of the AD has focused on the assessment of symptoms and is currently being tested for reliability and criterion validity.

Objectives: As no single informant can be considered the gold standard of child psychopathology, interviewing of children regarding their own symptoms is necessary. Our study focused on the reliability, validity, and clinical use of the Dominic Interactive (DI), a multimedia self-report screen to assess symptoms for the most frequent Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, mental disorders in school-aged children. Methods: A sample of 585 children aged 6 to 11 years from the community and psychiatric clinics was used to analyze the internal consistency, the test-retest estimate of reliability, and the criterion-related validity of the DI against the referral status. In addition, cross-informant correlation coefficients between this instrument (child report) and the Child Symptom Inventory (parent report) were explored in a subsample of 292 participants. Results: For the total sample, Cronbach alpha coefficients ranged from 0.63 to 0.91. Test–retest kappas varied from 0.42 to 0.62 for categories based on cut-off points, except for specific phobias. Intraclass correlation coefficients ranged from 0.70 to 0.81 for symptom scales. The DI discriminated between referred and nonreferred children in psychiatric clinics for all symptom scales. Significant cross-informant correlation coefficients were higher for the externalizing symptoms (0.35 to 0.48) than the internalizing symptoms (0.14 to 0.27). Conclusions: Findings of our study reasonably support adequate psychometric properties of the DI. This instrument offers a developmentally sensitive screening method to obtain unique information from young children about their mental health problems in front-line services, psychiatric clinics, and research settings.

Introduction Chart review is a low-cost, but highly informative, method to describe symptoms, treatment, and risk factors associated with borderline personality disorder (BPD) and to adapt screening and intervention to clinical reality. Previous chart review studies report more aggressiveness/anger and psychotic features in youths with BPD. They show that adverse family environment and parental psychopathology constitute important factors for BPD pathology. Objectives To examine clinical characteristics of depressed BPD adolescents (12–17 years old) outpatients according to gender and to explore variables which are associated with BPD traits. Methods A retrospective chart review using the child and adolescent version of the retrospective diagnostic instrument for borderlines was conducted on 30 depressed adolescents with BPD traits and 28 depressed patients without BPD traits. Participants who reached the retrospective diagnostic instrument for borderlines threshold for BPD were included in the BPD traits group. Comparison analyses were performed using Pearson’s Chi-square test. Associated factors were determined using regression analyses. Results BPD traits participants were characterized by higher family problems (parental psychopathology, parent disagreement/argument, and parent–child relational problem), more aggressive symptoms, and higher rates of family intervention and hospitalization. A number of familial factors (parental history of delinquency, substance use, personality disorders, having siblings, or parental disagreement/argument in boys) were associated with BPD traits. Attention seeking and problematic functioning (does not adapt well to group activities) were also associated with BPD traits. Discussion Our study stresses the need to assess BPD traits in adolescent psychiatric evaluation, especially in the presence of aggressive behaviors, family problems and attention seeking. Our results also highlight the importance of exploring family characteristics intervention in adolescents with BPD traits.
