Titre : Configurations of common childhood psychosocial risk factors Type de document : Texte imprimé et/ou numérique Auteurs : William COPELAND, Auteur ; Adrian ANGOLD, Auteur ; E. Jane COSTELLO, Auteur ; Lilly SHANAHAN, Auteur Année de publication : 2009 Article en page(s) : p.451-459 Langues : Anglais (eng) Mots-clés : Psychosocial-risk-factors psychiatric-disorders development sex-differences epidemiology Index. décimale : PER Périodiques Résumé : Background: Co-occurrence of psychosocial risk factors is commonplace, but little is known about psychiatrically-predictive configurations of psychosocial risk factors.
Methods: Latent class analysis (LCA) was applied to 17 putative psychosocial risk factors in a representative population sample of 920 children ages 9 to 17. The resultant class structure was retested in a representative population sample of 1420 children aged 9 to 13. In each sample, the child and one parent were interviewed with the Child and Adolescent Psychiatric Assessment. Concurrent psychiatric status was used to validate class membership.
Results: LCA identified five latent classes in both samples: two low risk classes; two moderate risk classes both involving family poverty configured with various other risk factors; and a high risk class characterized by family relational dysfunction and parental risk characteristics. Of the primary sample, 48.6% were categorized as low risk, 42.8% as moderate risk, and 8.6% as high risk. Moderate risk classes differed in their prediction of disruptive and emotional disorders depending on their specific risk factor configurations. High risk youth had the highest levels of both emotional and disruptive disorders. Combining our latent classes with a cumulative risk approach best accounted for the effects of risk factors on psychopathology in our primary sample.
Conclusions: Particular risk configurations have specific associations with psychiatric disorders. Configurational approaches are an important asset for large-scale epidemiological studies that integrate information about patterns of risk and disorders.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.02005.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=723

This study estimated patterns of diagnostic transitions from childhood to adolescence and from adolescence to early adulthood. Methods Patterns of diagnostic transitions were estimated using data from three prospective, longitudinal studies involving close to 20,000 observations of 3,722 participants followed across multiple developmental periods covering ages 9–30. Common DSM psychiatric disorders were assessed in childhood (ages 9–12; two samples), adolescence (ages 13–18; three samples), and early adulthood (ages 19 to age 32; three samples) with structured psychiatric interviews and questionnaires. Results Having a disorder at an early period was associated with at least a threefold increase in odds for having a disorder at a later period. Homotypic and heterotypic transitions were observed for every disorder category. The strongest evidence of continuity was seen for behavioral disorders (particularly ADHD) with less evidence for emotional disorders such as depression and anxiety. Limited evidence was found in adjusted models for behavioral disorders predicting later emotional disorders. Adult substance disorders were preceded by behavioral disorders, but not anxiety or depression. Conclusions Having a disorder in childhood or adolescence is a potent risk factor for a range of psychiatric problems later in development. These findings provide further support for prevention and early life intervention efforts and suggest that treatment at younger ages, while justified in its own right, may also have potential to reduce the risk for disorders later in development.

Titre : Longitudinal dimensionality of adolescent psychopathology: testing the differentiation hypothesis Type de document : Texte imprimé et/ou numérique Auteurs : Sonya K. STERBA, Auteur ; Helen Link EGGER, Auteur ; Adrian ANGOLD, Auteur ; E. Jane COSTELLO, Auteur ; Alaattin ERKANLI, Auteur ; William COPELAND, Auteur Année de publication : 2010 Article en page(s) : p.871-884 Langues : Anglais (eng) Mots-clés : Comorbidity Diagnostic-and-Statistical-Manual factor-analysis longitudinal dimensionality development internal-validity adolescent Axis-I-psychopathology Index. décimale : PER Périodiques Résumé : Background: The differentiation hypothesis posits that the underlying liability distribution for psychopathology is of low dimensionality in young children, inflating diagnostic comorbidity rates, but increases in dimensionality with age as latent syndromes become less correlated. This hypothesis has not been adequately tested with longitudinal psychiatric symptom data.
Methods: Confirmatory factor analyses of DSM-IV symptoms from seven common Axis I syndromes – major depression, generalized anxiety, separation anxiety, social anxiety, attention deficient hyperactivity, conduct, and oppositional defiant disorders – were conducted longitudinally, from ages 9 to 16, using the general-population Great Smoky Mountains Study sample.
Results: An eight-syndrome model fit well at all ages, and in both genders. It included social anxiety, separation anxiety, oppositional defiant, and conduct syndromes, along with a multidimensional attention deficit-hyperactivity syndrome (i.e., inattention, hyperactivity, and impulsivity) and a unidimensional major depression/generalized anxiety syndrome. A high degree of measurement invariance across age was found for all syndromes, except for major depression/generalized anxiety. Major depression and generalized anxiety syndromes slightly diverged at age 14–16, when they also began to explain more symptom variance. Additionally, correlations between some emotional and disruptive syndromes showed slight differentiation.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2010.02234.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=108

Titre : Specificity of putative psychosocial risk factors for psychiatric disorders in children and adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Lilly SHANAHAN, Auteur ; Adrian ANGOLD, Auteur ; E. Jane COSTELLO, Auteur ; William COPELAND, Auteur Année de publication : 2007 Article en page(s) : p.34–42 Langues : Anglais (eng) Mots-clés : Psychosocial-risk-factors psychiatric-disorders specificity development sex-differences epidemiology Index. décimale : PER Périodiques Résumé : Background: Most psychosocial risk factors appear to have general rather than specific patterns of association with common childhood and adolescence disorders. However, previous research has typically failed to 1) control for comorbidity among disorders, 2) include a wide range of risk factors, and 3) examine sex by developmental stage effects on risk factor–disorder associations. This study tests the specificity of putative psychosocial risk factors while addressing these criticisms.
Methods: Eight waves of data from the Great Smoky Mountains Study (N = 1,420) were used, covering children in the community age 9–16 years old. Youth and one parent were interviewed up to seven times using the Child and Adolescent Psychiatric Assessment, providing a total of 6,674 pairs of interviews. A wide range of putative neighborhood, school, peer, family, and child risk factors, and common and comorbid youth disorders were assessed.
Results: The majority of putative risk factors were specific to one disorder or one disorder domain. A unique or ‘signature set’ of putative risk factors was identified for each disorder. Several putative risk factors were associated with a disorder in preadolescent males, preadolescent females, adolescent males, or adolescent females only.
Conclusions: Our findings support the need to define risk factors and disorders narrowly, to control comorbidity and other risk factors, and to consider developmental patterns of specificity by sex.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2007.01822.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=310

Titre : Thresholds and accuracy in screening tools for early detection of psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : R. Christopher SHELDRICK, Auteur ; James C. BENNEYAN, Auteur ; Ivy Giserman KISS, Auteur ; Margaret J. BRIGGS-GOWAN, Auteur ; William COPELAND, Auteur ; Alice S. CARTER, Auteur Article en page(s) : p.936-948 Langues : Anglais (eng) Mots-clés : Assessment screening psychopathology developmental psychopathology methodology Index. décimale : PER Périodiques Résumé : Background The accuracy of any screening instrument designed to detect psychopathology among children is ideally assessed through rigorous comparison to ‘gold standard’ tests and interviews. Such comparisons typically yield estimates of what we refer to as ‘standard indices of diagnostic accuracy’, including sensitivity, specificity, positive predictive value (PPV), and negative predictive value. However, whereas these statistics were originally designed to detect binary signals (e.g., diagnosis present or absent), screening questionnaires commonly used in psychology, psychiatry, and pediatrics typically result in ordinal scores. Thus, a threshold or ‘cut score’ must be applied to these ordinal scores before accuracy can be evaluated using such standard indices. To better understand the tradeoffs inherent in choosing a particular threshold, we discuss the concept of ‘threshold probability’. In contrast to PPV, which reflects the probability that a child whose score falls at or above the screening threshold has the condition of interest, threshold probability refers specifically to the likelihood that a child whose score is equal to a particular screening threshold has the condition of interest. Method The diagnostic accuracy and threshold probability of two well-validated behavioral assessment instruments, the Child Behavior Checklist Total Problem Scale and the Strengths and Difficulties Questionnaire total scale were examined in relation to a structured psychiatric interview in three de-identified datasets. Results Although both screening measures were effective in identifying groups of children at elevated risk for psychopathology in all samples (odds ratios ranged from 5.2 to 9.7), children who scored at or near the clinical thresholds that optimized sensitivity and specificity were unlikely to meet criteria for psychopathology on gold standard interviews. Conclusions Our results are consistent with the view that screening instruments should be interpreted probabilistically, with attention to where along the continuum of positive scores an individual falls.
