Latent profile analysis of neuropsychological measures to determine preschoolers' risk for ADHD / Khushmand RAJENDRAN in Journal of Child Psychology and Psychiatry, 56-9 (September 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-9 (September 2015) . - p.958-965 Titre : Latent profile analysis of neuropsychological measures to determine preschoolers' risk for ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Khushmand RAJENDRAN, Auteur ; Sarah O'NEILL, Auteur ; David J.

HALPERIN, Auteur Article en page(s) : p.958-965 Langues : Anglais (eng) Mots-clés : Latent profile analysis  preschool  ADHD  neuropsychology Index. décimale : PER Périodiques Résumé : Background Hyperactive/Inattentive preschool children show clear evidence of neuropsychological dysfunction. We examined whether patterns and severity of test scores could reliably identify subgroups of preschoolers with differential risk for ADHD during school-age. Method Typically developing (TD: n = 76) and Hyperactive/Inattentive (HI: n = 138) 3–4 year olds were assessed annually for 6 years (T1–T6). Latent profile analysis (LPA) was used to form subgroups among the HI group based on objective/neuropsychological measures (NEPSY, Actigraph and Continuous Performance Test). Logistic regression assessed the predictive validity of empirically formed subgroups at risk for ADHD diagnosis relative to the TD group and to each other from T2 to T6. Results Latent profile analysis yielded two subgroups of HI preschoolers: (a) selectively weak Attention/Executive functions, and (b) pervasive neuropsychological dysfunction across all measures. Both subgroups were more likely to have ADHD at all follow-up time-points relative to the TD group (OR range: 11.29–86.32), but there were no significant differences between the LPA-formed subgroups of HI children at any time-point. Conclusions Objective/neuropsychological measures distinguish HI preschoolers from their TD peers, but patterns and severity of neuropsychological dysfunction do not predict risk for ADHD during school-age. We hypothesize that trajectories in at-risk children are influenced by subsequent environmental and neurodevelopmental factors, raising the possibility that they are amenable to early intervention.

A person-centered perspective on differential efficacy of early behavioral intervention in children with autism: A latent profile analysis / Isabelle PREFONTAINE in Research in Autism Spectrum Disorders, 97 (September 2022)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 97 (September 2022) . - 102017 Titre : A person-centered perspective on differential efficacy of early behavioral intervention in children with autism: A latent profile analysis Type de document : Texte imprimé et/ou numérique Auteurs : Isabelle PREFONTAINE, Auteur ; Julien MORIZOT, Auteur ; Marc J. LANOVAZ, Auteur ; Mélina RIVARD, Auteur Article en page(s) : 102017 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Differential response  EIBI  Heterogeneity  Latent profile analysis  Person-centered Index. décimale : PER Périodiques Résumé : Background Individuals with autism spectrum disorder (ASD) present heterogeneous symptom manifestations and responses to intervention. Despite being well-established, early intensive behavioral intervention (EIBI) has produced inconsistent responding across studies. Investigating individual differences and identifying more homogenous subgroups in samples may lead to a better understanding of symptom heterogeneity in ASD and response to EIBI. Method Adopting a person-centered perspective, we conducted latent profile analyses (LPA) to explore the presence of homogenous subgroups in our sample of 233 preschoolers with ASD receiving early behavioral intervention services. We investigated predictors of group membership using logistic multinomial regressions and outcomes of membership with the BCH approach available in Mplus. Results We found four latent profiles in our sample: a mild impairment profile, a severe impairment profile, and two intermediate profiles with combinations of mild to moderate autistic symptoms, adaptive functioning, and intellectual functioning. Only the annual family income predicted profile membership. All profiles made progress during the intervention period, with varying magnitudes of change. During the follow-up period, the moderate impairment and the severe impairment profiles showed stability or improvement in adaptive functioning, while the two mild impairment profiles showed a slight decrease. Conclusions Our study contributes to the literature by suggesting the presence of distinct profiles with differences in their response to EIBI. The profiles associated with better short-term outcomes were different than the profiles who maintain their gains more consistently over time. This finding may guide both practitioners and researchers assessing the effects of intervention.

Spectrum or subtypes? A latent profile analysis of restricted and repetitive behaviours in autism / Lidan ZHENG in Research in Autism Spectrum Disorders, 57 (January 2019)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 57 (January 2019) . - p.46-54 Titre : Spectrum or subtypes?

One way of understanding this heterogeneity is by investigating whether homogenous subgroups within the autism population exist. Some studies have attempted to do this by looking at social and communication skills. However, few studies have looked at subtyping using restricted and repetitive behaviours. While restricted and repetitive behaviours form part of the core features of autism, their presentation is diverse across different individuals on the spectrum. The aim of this study was to determine if restricted and repetitive behaviours could be used to identify potential subtypes of autism. Method This study used unsupervised clustering algorithms to differentiate subgroups of individuals on the autism spectrum based on their scores on the Repetitive Behaviour Scale-Revised (RBS-R). Results Three groups were found that reported low, medium and high levels of restricted and repetitive behaviours. These groups also differed on a range of clinical measures including problematic behaviours, autistic traits and adaptive behaviours. Conclusions Our findings indicate that subgroups of individuals with autism can be identified based on their level of restricted and repetitive behaviours. This highlights that restricted and repetitive behaviours may be best understood under a dimensional continuum of severity. This has implications for our understanding of the non-social characteristics of autism.

Classifying childhood war trauma exposure: latent profile analyses of Sierra Leone's former child soldiers / S. SU in Journal of Child Psychology and Psychiatry, 62-6 (June 2021)

To examine which groups of former child soldiers are more likely to have difficulties with emotion regulation, interpersonal relationships, and mental health postconflict, we explored patterns of war trauma exposure and their effects on subsequent mental health problems among former child soldiers in Sierra Leone. METHODS: Participants were 415 (23.86% female) Sierra Leonean former child soldiers participating in a 15-year, four-wave longitudinal study. At T1 (2002), 282 former child soldiers (aged 10-17) were recruited. T2 (2004) included 186 participants from T1 and an additional cohort of self-reintegrated former child soldiers (NT2 = 132). T3 (2008) and T4 (2016/2017) participants were youth enrolled in previous waves (NT3 = 315; NT4 = 364). Latent profile analysis (LPA) was used to classify participants based on the first-time reports of eight forms of war exposure (separation and loss of assets, parental loss, loss of loved ones, witnessing violence, victimization, perpetrating violence, noncombat activities, and deprivation). ANOVA examined whether patterns of war exposure were associated with sociodemographic characteristics and mental health outcomes between T1 and T4. RESULTS: LPA identified two profiles: higher exposure versus lower exposure, using cumulative scores of eight forms of war-related trauma exposure. The 'higher war exposure' group comprised 226 (54.5%) former child soldiers and the 'lower war exposure' group included 189 (45.5%). Significantly higher levels of violence-related and combat experiences characterized the group exposed to more traumatic events. The 'higher war exposure' group reported more PTSD symptoms at T2, more hyperarousal symptoms across all waves, and more difficulties in emotion regulation at T4. CONCLUSIONS: Former child soldiers exposed to higher levels of war-related traumatic events and loss should be prioritized for mental health services immediately postconflict and as they transition into adulthood.
