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

Type de document : texte imprimé Auteurs : Eoin MCELROY, Auteur ; Jay BELSKY, Auteur ; Natacha CARRAGHER, Auteur ; Pasco 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.

In search of disorders: internalizing symptom networks in a large clinical sample / Eoin MCELROY in Journal of Child Psychology and Psychiatry, 60-8 (August 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-8 (August 2019) . - p.897-906 Titre : In search of disorders: internalizing symptom networks in a large clinical sample Type de document : texte imprimé Auteurs : Eoin MCELROY, Auteur ; Praveetha PATALAY, Auteur Article en page(s) : p.897-906 Langues : Anglais (eng) Mots-clés : Nosology  anxiety  comorbidity  depression  developmental psychopathology  network analysis Index. décimale : PER Périodiques Résumé : BACKGROUND: The co-occurrence of internalizing disorders is a common form of psychiatric comorbidity, raising questions about the boundaries between these diagnostic categories. We employ network psychometrics in order to: (a) determine whether internalizing symptoms cluster in a manner reflecting DSM diagnostic criteria, (b) gauge how distinct these diagnostic clusters are and (c) examine whether this network structure changes from childhood to early and then late adolescence. METHOD: Symptom-level data were obtained for service users in publicly funded mental health services in England between 2011 and 2015 (N = 37,162). A symptom network (i.e. Gaussian graphical model) was estimated, and a community detection algorithm was used to explore the clustering of symptoms. RESULTS: The estimated network was densely connected and characterized by a multitude of weak associations between symptoms. Six communities of symptoms were identified; however, they were weakly demarcated. Two of these communities corresponded to social phobia and panic disorder, and four did not clearly correspond with DSM diagnostic categories. The network structure was largely consistent by sex and across three age groups (8-11, 12-14 and 15-18 years). Symptom connectivity in the two older age groups was significantly greater compared to the youngest group and there were differences in centrality across the age groups, highlighting the age-specific relevance of certain symptoms. CONCLUSIONS: These findings clearly demonstrate the interconnected nature of internalizing symptoms, challenging the view that such pathology takes the form of distinct disorders.

Network Analysis of Internet Addiction Symptoms Among a Clinical Sample of Japanese Adolescents with Autism Spectrum Disorder / Tomoya HIROTA in Journal of Autism and Developmental Disorders, 51-8 (August 2021)

Our analysis revealed that defensive and secretive behaviors and concealment of internet use were identified as central symptoms in this population, suggesting that mitigating these symptoms potentially prevent the development and/or maintenance of IA in adolescents with ASD. Providing adolescents and their caregivers with psychoeducation on the role of central symptoms above in IA can be a salient intervention. Doing so may facilitate nonconflicting conversations between them about adolescents' internet use and promote more healthy adolescents' internet use behavior.

It is important to understand how their influence may vary across contexts. We investigated structural (e.g. household size), functional (e.g. social support) and quality (e.g. feeling close) social connection factors in relation to adolescent internalising and externalising symptoms, comparing two countries Brazil and the United Kingdom (UK). Methods We pooled data from the UK Millennium Cohort Study (MCS) and the Brazilian High Risk Cohort Study (BHRCS). We included 12 social connection variables, identified through retrospective harmonisation and lived experience expert involvement. We tested measurement invariance and conducted multiple regressions to analyse associations between the social connection factors (age 14) and later internalising and externalising difficulties (age 17.5) in both cohorts. We investigated country-level interactions and used weights to account for attrition, survey design, population representativeness and sample size. Results We found pooled main associations with later internalising symptoms for ?living with half-siblings? (p < .001), ?moving address? (p .001), ?mother marital status? (p < .001 .003), ?bullying? (p .001), ?being bullied? (p < .001) and ?difficulties keeping friends? (p < .001). For externalising, we found main associations with ?household size? (p .041), ?moving address? (p .041), ?mother's marital status? (p .001 .013), ?bullying others? (p < .001) and ?being bullied? (p < .001). Country-level interactions suggested higher internalising symptoms were associated with ?household size? (p .001) in Brazil and ?being bullied? (p < .001) in MCS. Additionally, ?half-siblings in household? (p .003), ?poor mother?child relationship? (p .018), ?single mother? (p .035), ?bullying? (p < .001) and ?being bullied? (p < .001) were more strongly linked to externalising difficulties in MCS. Conclusions Social connection factors, mostly structural, contributed to adolescent internalising and externalising difficulties in both countries. Factors relating to bullying and family composition seem to play a stronger role in each country. Cultural and socioeconomic factors might explain these differences. Future research should investigate cross-regional differences to meaningfully inform global mental health efforts.

Socioeconomic and sex inequalities in parent-reported adolescent mental ill-health: time trends in four British birth cohorts / Eoin MCELROY in Journal of Child Psychology and Psychiatry, 64-5 (May 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-5 (May 2023) . - p.758-767 Titre : Socioeconomic and sex inequalities in parent-reported adolescent mental ill-health: time trends in four British birth cohorts Type de document : texte imprimé Auteurs : Eoin MCELROY, Auteur ; Marc TIBBER, Auteur ; Pasco FEARON, Auteur ; Praveetha PATALAY, Auteur ; George B. PLOUBIDIS, Auteur Article en page(s) : p.758-767 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Studies using symptom-based screeners have suggested that mental ill-health has increased in adolescents in recent decades, however, few studies have tested the equivalence of their instruments, which is critical for inferring changes in prevalence. In addition, little research has explored whether socioeconomic position (SEP) and sex inequalities in adolescent mental health have changed over time. Methods Using structural equation modelling, we explored SEP and sex differences in harmonised parent reports of emotional and behavioural problems, using data from four UK birth cohorts: the 1958 National Child Development Study (NCDS'58; n = 10,868), the 1970 British Cohort Study (BCS'70; n = 8,242), the 1991-92 Avon Longitudinal Study of Parents and Children (ALSPAC'91; n = 5,389), and the 2000-01 Millennium Cohort Study (MCS'01; n = 9,338). Results Compared with the two earliest cohorts, members of MCS'01 had higher latent mean scores on emotional problems (both sexes), and lower scores on behavioural problems (females only). The associations between four indicators of SEP and emotional problems were strongest in MCS'01, with housing tenure having the strongest association. All four SEP indicators were associated with behavioural problems in each cohort, with housing tenure again more strongly associated with problems in the MCS'01. Mediation analyses suggested that the increase in emotional problems occurred despite broadly improving socioeconomic conditions. Conclusions Our findings suggest that parent reports of adolescent emotional problems, but not behavioural problems, have risen in recent generations and this trend is not solely due to reporting styles. A failure to address widening social inequalities may result in further increases in mental ill-health amongst disadvantaged young people.
