Developmental stability of general and specific factors of psychopathology from early childhood to adolescence: dynamic mutualism or p-differentiation? / E. MCELROY in Journal of Child Psychology and Psychiatry, 59-6 (June 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-6 (June 2018) . - p.667-675 Titre : Developmental stability of general and specific factors of psychopathology from early childhood to adolescence: dynamic mutualism or p-differentiation? Type de document : Texte imprimé et/ou numérique Auteurs : E. MCELROY, Auteur ; J. BELSKY, Auteur ; Natacha CARRAGHER, Auteur ; P. FEARON, Auteur ; Praveetha PATALAY, Auteur Article en page(s) : p.667-675 Langues : Anglais (eng) Mots-clés : Comorbidity  continuity  developmental psychopathology  externalizing disorder  internalizing disorder Index. décimale : PER Périodiques Résumé : BACKGROUND: Recent research indicates that the best-fitting structural model of psychopathology includes a general factor capturing comorbidity (p) and several more specific, orthogonal factors. Little is known about the stability of these factors, although two opposing developmental processes have been proposed: dynamic mutualism suggests that symptom-level interaction and reinforcement may lead to a strengthening of comorbidity (p) over time, whereas p-differentiation suggests a general vulnerability to psychopathology that gives way to increasingly distinct patterns of symptoms over time. In order to test both processes, we examine two forms of developmental stability from ages 2 to 14 years: strength (i.e., consistency in the amount of variance explained by general and specific factors) and phenotypic stability (i.e., homotypic and heterotypic continuity). METHODS: Data are from the NICHD Study of Early Child Care and Youth Development. Psychopathology symptoms were assessed nine times between ages 2 and 14 years (n = 1,253) using the Child Behavior Checklist completed by mothers. Confirmatory bifactor modeling was used to test structural models of psychopathology at each age. Consistency in strength was examined by calculating the Explained Common Variance (ECV) and phenotypic stability was investigated with cross-lagged modeling of the general and specific factors. RESULTS: Bifactor models fit the data well across this developmental period. ECV values were reasonably consistent across development, with the general factor accounting for the majority of shared variance (61%-71%). Evidence of both homotypic and heterotypic continuity emerged, with most heterotypic continuity involving the general factor, as it both predicted and was predicted by specific factors. CONCLUSIONS: A bifactor model effectively captures psychopathological comorbidity from early childhood through adolescence. The longitudinal associations between the general and specific factors provide evidence for both the hypothesized processes (dynamic mutualism and p-differentiation) occurring through development.

The long-term effectiveness of a selective, personality-targeted prevention program in reducing alcohol use and related harms: a cluster randomized controlled trial / Nicola C. NEWTON in Journal of Child Psychology and Psychiatry, 57-9 (September 2016)

NAIR, Auteur ; Lexine STAPINSKI, Auteur ; Maree TEESSON, Auteur Article en page(s) : p.1056-1065 Langues : Anglais (eng) Mots-clés : Prevention  personality  alcohol abuse  adolescence  school Index. décimale : PER Périodiques Résumé : Background This study investigated the long-term effectiveness of Preventure, a selective personality-targeted prevention program, in reducing the uptake of alcohol, harmful use of alcohol, and alcohol-related harms over a 3-year period. Methods A cluster randomized controlled trial was conducted to assess the effectiveness of Preventure. Schools were block randomized to one of two groups: the Preventure group (n = 7 schools) and the Control group (n = 7 schools). Only students screening as high-risk on one of four personality profiles (anxiety sensitivity, negative thinking, impulsivity, and sensation seeking) were included in the analysis. All students were assessed at five time points over a 3-year period: baseline; immediately after the intervention; and 12, 24, and 36 months after baseline. Students were assessed on frequency of drinking, binge drinking, and alcohol-related harms. Two-part latent growth models were used to analyze intervention effects, which included all students with data available at each time point. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12612000026820; www.anzctr.org.au). Results A total of 438 high-risk adolescents (mean age, 13.4 years; SD = 0.47) from 14 Australian schools were recruited to the study and completed baseline assessments. Relative to high-risk Control students, high-risk Preventure students displayed significantly reduced growth in their likelihood to consume alcohol [b = ?0.225 (0.061); p < .001], to binge drink [b = ?0.305 (.096); p = 0.001], and to experience alcohol-related harms [b = ?0.255 (0.096); p = .008] over 36 months. Conclusions Findings from this study support the use of selective personality-targeted preventive interventions in reducing the uptake of alcohol, alcohol misuse, and related harms over the long term. This trial is the first to demonstrate the effects of a selective alcohol prevention program over a 3-year period and the first to demonstrate the effects of a selective preventive intervention in Australia.

The structure of psychopathology and association with poor sleep, self-harm, suicidality, risky sexual behavior, and low self-esteem in a population sample of adolescents / Matthew SUNDERLAND in Development and Psychopathology, 33-4 (October 2021)

However, relatively little evidence has emerged regarding the validity of this model with respect to a range of factors that have been previously implicated across multiple disorders. The current study utilized a cross-sectional population survey of adolescents (n = 2,003) to examine the extent to which broad psychopathology factors account for specific associations between psychopathology and key validators: poor sleep, self-harm, suicidality, risky sexual behavior, and low self-esteem. Confirmatory factor models, latent class models, and factor mixture models were estimated to identify the best structure of psychopathology. Structural equation models were then estimated to examine the broad and specific associations between each psychopathology indicator and the validators. A confirmatory factor model with three lower-order factors, representing internalizing, externalizing, and psychotic-like experiences, and a single higher-order factor evidenced the best fit. The associations between manifest indicators of psychopathology and validators were largely nonspecific. However, significant and large direct effects were found between several pairwise associations. These findings have implications for the identification of potential targets for intervention and/or tailoring of prevention programs.
