The relationship between intelligence and global adaptive functioning in young people with or without neurodevelopmental disorders. Psychiatry Res 2021; 303:114076.

Abstract
Previous studies have shown an association between IQ and adaptive global functioning, i.e. how well a person is functioning in different domains of life. However, it is unclear to what extent such an association applies in children with neurodevelopmental disorders (NDDs). The study group consisted of 550 population-screened children assessed with the K-SADS, WISC-IV, and the C-GAS. Approximately half of the sample had been diagnosed with one or several NDDs (ADHD, autism, language disorder and tic disorder). A factorial ANOVA with IQ level and the presence of NDD was conducted, with C-GAS score as the dependent variable. Results revealed a significant interaction effect between IQ-group and NDD-status. In the non-NDD group (49% girls), higher IQ scores were clearly linked with better global adaptive functioning. Among children with NDDs (35% girls), however, higher IQ scores were not clearly associated with better functioning. Thus, the association between IQ and adaptive functioning were found to differ depending on the presence of NDD. These results have implications for the interpretation of IQ test results in neurodevelopmental assessments and point towards the importance of providing support based on an assessment of needs and functioning rather than scores from IQ tests.

Abstract
LAY ABSTRACT Individuals diagnosed with autism tend to process sensory information differently than individuals without autism, resulting for instance in increased sensitivity to sounds or smells. This leads to challenges in everyday life and may restrict the individual's daily functioning. How direct this link is, however, is currently unclear. We investigated this question in 289 twins of whom 60 were diagnosed with autism and further 61 were diagnosed with other neurodevelopmental disorders. We looked at the association between unusual sensory processing and adaptive skills, both across individuals and within-twin pairs, testing whether individuals with higher levels of atypical sensory processing showed reduced adaptive skills compared to their twins. Since twins share 50%-100% of their genes and part of their environment (e.g. family background), associations within-twin pairs are free from effects of these familial factors. We found that an increased sensitivity to, as well as the avoiding of, sensory input (hyper-responsiveness) was linked to reduced adaptive skills across individuals-but not within-twin pairs. We also found an association between the degree to which individuals seek for sensory input (sensation seeking) and reduced adaptive skills, but only in individuals diagnosed with autism. The results suggest that sensory hyper-responsiveness has negative effects on individuals' general ability to function, but that this link is influenced by familial factors and hence not direct. In addition, sensation seeking behaviors might have a negative impact on adaptive skills specifically in autistic individuals.

Abstract
BACKGROUND Since the DSM-5, adaptive functioning has taken a prominent place in the classification of intellectual disability (ID). The ADAPT was developed to assess adaptive skills in individuals with ID. METHOD A total of 2,081 ADAPTs from clients with suspected ID or borderline intellectual functioning and 129 ADAPTs from people from the general population (non-ID) were collected, along with background characteristics. RESULTS Internal consistency of the ADAPT was high (α = 0.98). ADAPT scores were positively associated with IQ, educational level and level of independent living. Furthermore, individuals without ID scored significantly higher than the clients on all of the 65 ADAPT items. Reference values were established for different IQ groups and living situations. CONCLUSION Results suggest that the ADAPT is a valid instrument for measuring adaptive skills in individuals with ID. The reference values may be used for the purpose of estimating the level of ID and the needed intensity of support.

Abstract
Objectives: The concept of narcissism contains a yet unresolved paradox: Its grandiose facet depicts the psychopathological core but is often associated with life-satisfaction and overall functioning, whereas its vulnerable facet is associated with psychological distress, but still not included in the international classification systems. Our goal was to investigate the relationship between the two facets of narcissism expecting underlying defense mechanisms to be core elements. First, we aimed to identify defense mechanisms specific to grandiose and vulnerable narcissism. Second, we explored how both facets are differentially associated with psychological distress, assuming that grandiose narcissism would be associated with less psychological distress than vulnerable narcissism. Third, we investigated the mediating role of defense mechanisms between narcissism and psychological distress. Methods: In a non-clinical sample of N = 254 individuals, the Pathological Narcissism Inventory was used for the assessment of grandiose and vulnerable facets of narcissism, the Defense Style Questionnaire for defense mechanisms, and the Brief Symptom Inventory for psychological distress. Structural equation modeling was employed to identify distinct factors of grandiose and vulnerable narcissism. Associations between specific defense mechanisms and both facets were calculated. Furthermore, the direct association between both facets and psychological distress was examined. We finally explored whether defense mechanisms mediate the association between distress and both grandiose and vulnerable narcissism. Results: A distinct pattern of defense mechanisms for each facet of narcissism could be extracted: Both facets showed significant positive correlations with specific intermediate and all maladaptive defense mechanisms. Only grandiose narcissism showed significant positive correlations with adaptive defenses. Vulnerable narcissism showed negative correlations with all adaptive defenses. Specifically, grandiose narcissism was significantly related to anticipation, pseudo-altruism, rationalization, and dissociation, whereas vulnerable narcissism was negatively related to all these defense mechanisms. While grandiose narcissism was not related to psychological distress, vulnerable narcissism showed high correlations with psychological distress. Intriguingly, mediator analysis found that grandiose narcissism was related to psychological distress when mediated by maladaptive defense mechanisms. Discussion: The role of defense mechanisms is central for a differentiated understanding of the two different faces of narcissism. The relevance of assessing defense mechanisms in clinical settings, and related empirical findings are discussed.

Abstract
LAY ABSTRACT Adaptive functioning describes the age-appropriate skills necessary for independent living. Research suggests that autistic children, adolescents, and adults who do not have an intellectual disability demonstrate adaptive functioning challenges relative to their intellectual ability. Thus, even though many of these individuals have the intellectual capacity to excel in mainstream educational and vocational settings, their adaptive functioning challenges may serve as an obstacle to independence. The research on adaptive functioning in autistic adults is focused on statistical analysis of standardized assessments (e.g. parent-report on multiple choice questionnaires). Qualitative research that examines the narratives of young adults and their parents is needed to better understand adaptive functioning in young adults and their resulting service needs. This study combined statistical analysis of standardized assessments with qualitative analysis of interview responses from autistic young adults without intellectual disability and their parents. Findings replicated previous reports of adaptive functioning challenges and identified influences on adaptive functioning development, consequences of independence, and service needs. Taken together, findings indicate the need for interventions and services that facilitate adaptive functioning development in autistic adolescents and young adults and provide insight into potential intervention targets and strategies.

Abstract
Little is known about how youth with spina bifida (SB) acquire adaptive functioning skills across development. Therefore, the current study examined: (1) trajectories of adaptive functioning in youth with SB as they transitioned from childhood into adolescence, and (2) neuropsychological functioning as a potential risk factor for long-term adaptive functioning difficulties. Participants (n = 131 youth with SB) were recruited as part of a larger ongoing longitudinal study. Growth curves were used to examine changes over time across six adaptive functioning skills: communication, self-direction, functional academics, social, self-care, and home living skills. Additionally, youth's attention and executive functioning (i.e., working memory, planning/organizational skills, cognitive flexibility, inhibition) were assessed via questionnaires and performance-based assessments, and entered as predictors in the models. Youth's communication, self-direction, functional academics, self-care, and home living skills increased over time across age, whereas youth's social skills did not. Scaled scores for youth's social, communication, self-direction, and functional academics skills were generally within normal limits, whereas those for self-care and home living skills fell in the borderline range. Better attention and executive functioning predicted a higher intercept for many adaptive functioning abilities at 11.5 years old, above and beyond the influence of IQ. However, these variables did not predict growth in adaptive functioning. Results indicate that youth with SB acquire skills across development to better meet the demands of daily life. However, youth with poorer neurocognitive functioning may demonstrate adaptive functioning deficits in early childhood and benefit from timely intervention.

Abstract
Sex differences in restricted and repetitive behaviors (RRBs) in individuals with Autism Spectrum Disorder (ASD) have been explored with mixed findings. We aimed to investigate sex differences in RRBs through a specific measure—i.e., the Repetitive Behavior Scale Revised (RBS-R)—in a sample of preschool-age and school-age children with ASD. Additionally, we evaluated if RRBs were differently related to adaptive functioning within the male and the female age groups. A sample of 210 ASD individuals (3–18 years; 145 males, 65 females) underwent an in-depth assessment including a cognitive, adaptive functioning evaluation (i.e., the Adaptive Behavior Assessment System, Second Edition (ABAS-II)) and RRBs assessment (i.e., RBS-R). No significant sex differences on the RBS-R total score or any RBS-R subscale emerged. Within the group of older participants, RRBs were negatively associated with all adaptive skill domains independently from sex and age. Our results suggest a lack of sex differences in RRBs in our sample. Additionally, our findings highlight the possible negative impact of RRBs on adaptive skills in older individuals with autism, emphasizing the need for autistic individuals of both sexes to undergo an early intervention targeting RRBs, in order to improve their adaptive skills.

Abstract
KBG syndrome (KBGS) is a rare Mendelian condition caused by heterozygous mutations in ANKRD11 or microdeletions in chromosome 16q24.3 encompassing the gene. KBGS is clinically variable, which makes its diagnosis difficult in a significant proportion of cases. The present study aims at delineating the cognitive profile and adaptive functioning of children and adolescents with KBGS. Twenty-four Italian KBGS with a confirmed diagnosis by molecular testing of the causative ANKRD11 gene were recruited to define both cognitive profile as measured by the Wechsler Intelligence Scale and adaptive functioning as measured by Vineland Adaptive Behavior Scales-II Edition or the Adaptive Behavior Assessment System-II Edition. Among children and adolescents, 17 showed intellectual disability, six presented borderline intellectual functioning and only one child did not show cognitive defects. Concerning cognitive profile, results revealed significant differences between the four indexes of Wechsler Intelligence Scale. Namely, the verbal comprehension index was significantly higher than the perceptual reasoning index, working memory index and the processing speed index. Concerning adaptive functioning, no difference between the domains was found. In conclusion, in our cohort, a heterogeneous profile has been documented in cognitive profiles, with a spike on verbal comprehension, while a flat-trend has emerged in adaptive functioning. Our cognitive and adaptive characterization drives professionals to set the best clinical supports, capturing the complexity and heterogeneity of this rare condition.

Abstract
Erikson's psychosocial developmental theory assumes that valence of one's identity (i.e., identity content valence) defined by positive and negative identity elements is important for understanding patterns of (mal)adaptation. However, previous empirical research on identity and (mal)adaptation has focused on how individuals deal with identity issues (e.g., exploration and commitment), while neglecting identity content valences. In contrast, this study assessed identity content valences in terms of positive and negative identity elements. Theoretically, identity content valences affect (mal)adaptation, whereas individuals' (mal)adaptation influences their identities. Consequently, this study examined reciprocal relationships between identity content valences and adaptation (i.e., prosocial behaviors) and maladaptation (e.g., externalizing symptoms) in a sample of Japanese young adults, including socioculturally relevant indicators of maladaptation (i.e., hikikomori symptoms and suicidal ideation). This study includes 2,313 Japanese young adults who participated in a three-wave longitudinal study. The cross-lagged panel model and random intercept cross-lagged panel model revealed reciprocal relationships between identity content valences and (mal)adaptation at the between-person level. Negative identity elements positively predicted suicidal ideation. Meanwhile, prosocial behaviors positively predicted positive identity elements, whereas hikikomori symptoms and suicidal ideation positively predicted negative identity elements. These relationships were significant only for socioculturally relevant indicators, suggesting the importance of considering sociocultural contexts.

Abstract
Difficulties in adaptive functioning are common in autism spectrum disorder (ASD) and contribute to negative outcomes across the lifespan. Research indicates that cognitive ability is related to degree of adaptive functioning impairments, particularly in young children with ASD. However, the extent to which other factors, such as socioeconomic status (SES) and ASD symptom severity, predict impairments in adaptive functioning remains unclear. The goal of this study was to determine the extent to which SES, ASD symptom severity, and cognitive ability contribute to variability in domain-specific and global components of adaptive functioning in preschool-aged children with ASD. Participants were 99 preschool-aged children (2-6 years) with ASD who attended a tertiary diagnostic service. Results demonstrate that cognitive ability accounted for a significant proportion of variance in domain-specific and global components of adaptive functioning, with higher cognitive ability predicting better adaptive functioning. Results also demonstrate that SES accounted for some variability in domain-specific communication skills and global adaptive functioning when compared to basic demographic factors alone (age and gender). By contrast, ASD symptom severity did not predict variability in domain-specific or global components of adaptive functioning. These findings provide support for a relationship between cognitive ability and adaptive functioning in preschool-aged children with ASD and help to explain specific contributions of verbal and nonverbal ability to adaptive functioning; from this, we can better understand which children are likely to show the greatest degree of impairments across components of adaptive functioning early in development. LAY SUMMARY: People with autism often have difficulties with everyday communication, daily living, and social skills, which are also called adaptive functioning skills. This study investigated factors that might be related to these difficulties in preschoolers with autism. We found that better cognitive ability, but not autism symptoms, were associated with better adaptive functioning. This suggests that interventions for young children with autism should take into account cognitive ability to better understand which children are likely to have difficulties with adaptive functioning.

Abstract
LAY ABSTRACT Adaptive functioning refers to skills that are vital to success in day-to-day life, including daily living (e.g. grocery shopping, food preparation, transportation use), communication (e.g. verbal expression of needs), and socialization skills (e.g. interpersonal skills, including expressing and recognizing emotions, and understanding turn-taking in conversation). Among autistic individuals without intellectual disability, adaptive functioning is not commensurate with intellectual ability (IQ), and instead a gap exists between these individuals' intellectual ability and their adaptive skills. Further, these autistic individuals show a widening of this gap with increasing age. Existing studies of the gap between IQ and adaptive functioning have studied predominantly male samples. Thus, we do not know if the gap also exists in autistic females. We therefore looked at adaptive functioning and the gap between IQ and adaptive functioning in a large sample of autistic girls and boys without intellectual disability. To disentangle effects of group (autistic vs typically developing) from effects of sex (girls vs boys), we compared autistic girls and boys to one another as well as to their same-sex typically developing peers. Analyses took into consideration differences in IQ between autistic and typically developing youth. We found autistic girls, like autistic boys, show lower adaptive functioning than their same-sex typically developing peers. Results underscore the need to evaluate adaptive functioning in autistic individuals without intellectual disability and to provide necessary supports. The large gap between intellectual ability and socialization skills, in particular, may be of critical importance in improving our understanding of outcomes and mental health difficulties among autistic females.

Abstract
The intellectual functioning of people with autism spectrum disorder (ASD) without intellectual developmental disorder (IDD) has not been widely studied. However, marked heterogeneity in assessment measures, samples, and results has been an obstacle for the generalization of findings. We aimed to (a) describe WISC-V intellectual functioning in a sample of children with autism spectrum disorder without intellectual developmental disorder, (b) identify WISC-V profiles, and (c) explore whether WISC-V intellectual functioning is related to ASD symptom severity and adaptive skills. Our sample consisted of 121 children from 6 to 16 years of age with ascertained ASD without an intellectual developmental disorder (IDD). The intellectual functioning of the participants was within the average range. Intra-individual analysis showed that children with ASD performed better on visual than auditory working-memory tasks. Moreover, the intellectual functioning of the participants correlated negatively with ASD symptom severity but positively with adaptive communication skills. Overall, we identified six intellectual profiles according to verbal and reasoning skills. These findings highlight the relevance of WISC-V assessment for children with ASD without an IDD to individualize intervention, especially remediation. LAY SUMMARY: This study examined WISC-V intellectual functioning in 121 children with autism spectrum disorder (ASD) without an intellectual developmental disorder (IDD). We found their intellectual functioning to be within the average, as was that of their peers with typical development (TD), and their verbal and reasoning skills were the most discriminant. In addition, the better their intellectual functioning was, the better their adaptive communication skills and the less severe their ASD symptoms. These findings highlight the relevance of WISC-V assessment in ASD to individualize early psychological remediation.

Abstract
PURPOSE Brain tumor (BT) survivors are at risk for difficulties with adaptive functioning (AF). Recent work has associated neurological risk with poorer AF outcomes using the Neurological Predictor Scale (NPS), a quantification of neurological risk factors. Survivors also have poorer attention, processing speed, and working memory, which are all important for AF. The current study examined whether these cognitive constructs explain the relationship between the NPS and AF in survivors. METHODS Ninety-five adult BT survivors and 135 healthy controls were recruited from the Atlanta area. The Oral Symbol Digits Modalities test was used to measure processing speed, Digit Span Backward assessed working memory, and Digit Span Forward measured attention. Informants completed the Scales of Independent Behavior (SIB-R) to measure AF. Group differences and correlations were assessed, and the PROCESS macro for SPSS tested indirect effects. RESULTS Survivors were significantly lower on AF and cognitive measures compared with controls. Attention span and processing speed had significant indirect effects in relationship between NPS and AF individually, but processing speed was the only variable with a significant indirect effect when all cognitive variables were included in the model. The NPS and processing speed together account for approximately 39% of variance in AF outcomes. CONCLUSIONS BT survivors in our sample have lower AF than controls, and processing speed appears to be particularly important in explaining the relationship between neurological risk and AF. In the future, the development of interventions aimed at increasing young adult independence should target both cognitive processing speed and AF skills.

Abstract
OBJECTIVE To evaluate the level of adaptive functioning in patients with attention deficit hyperactivity disorder (ADHD). MATERIALS AND METHODS One hundred children and adolescents with ADHD (79 male and 21 female) were examined using M. Weiss functional impairment rating scale (WFIRS). The total score on the ADHD-DSM-IV was at least 24 and ADHD severity was rated as «Moderately ill» or «Markedly ill» on CGI-S-ADHD scale. RESULTS Typical for ADHD difficulties with adaptive functioning in «Family», «Learning and school», «Life skills», «Social activities» domains are more pronounced in «Markedly ill» patients compared to «Moderately ill» and increase during the transition from childhood to adolescence. Comorbid disorders (oppositional defiant disorder and anxiety disorders) lead to a significant increase in adaptive functioning impairments in most domains of daily life, including «Family», «Learning and school», «Child's self concept», «Social activities» and «Risky activities». CONCLUSION It is necessary not only to assess core symptoms in the follow-up of patients with ADHD, but also evaluate comorbid disorders and the level of functional impairment across the main domains of daily life.

Abstract
OBJECTIVE We examined growth trajectories of hippocampal volume (HV) in early childhood in a longitudinal cohort of male and female participants with autism spectrum disorder (ASD) and typically developing (TD) individuals, and investigated HV in those with large brains. Relations between factors potentially associated with hippocampal size and growth were investigated. METHOD Participants received 1 to 3 structural magnetic resonance imaging scans between ages 25 and 80 months (unique participants: ASD, n =200; TD, n =110; total longitudinal scans, n = 593). HV growth during this period was examined using mixed-effects linear models. Associations between early HV and growth rates, and IQ and adaptive functioning, were evaluated. RESULTS After accounting for cerebral hemisphere volume, male participants exhibited larger left and right HV than female participants. Hippocampal growth rates did not differ by sex. In children with larger hemisphere volumes, male and female participants with ASD had relatively larger HV than TD participants of similar hemisphere volume. This effect was present in a broader group than only those with disproportionate megalencephaly (male participants with large cerebral volumes relative to body size). Right hippocampi were larger than left hippocampi in both groups and sexes. Right versus left volume differences were greater for ASD. After adjusting for hemisphere volume, male participants with ASD showed a significant positive association between right hippocampal growth and adaptive behavior. CONCLUSION HV was relatively greater in ASD in analyses adjusting for hemisphere volume, whereas only subtle differences were observed in HV and growth between participants with ASD and TD participants in unadjusted analyses, suggesting that ASD involves atypical coupling between HV and brain size.

Abstract
LAY ABSTRACT Temperament is often thought of as behavioural traits that are relatively stable over time but can vary between individuals. Children diagnosed with autism spectrum disorder are often characterized as having 'reactive' and 'negative' temperaments when compared to same-aged peers with or without disabilities, which can negatively impact the development of adaptive functioning skills but little is known about variations of temperament between individual children diagnosed with autism spectrum disorder. This study aimed to (a) explore the variation of individual temperament traits within a sample of school-aged children with autism spectrum disorder to determine whether subgroups with similar trait profiles emerge and (b) examine whether temperament influences the relationship between autism symptoms and adaptive functioning outcomes. Results from our dataset suggest that children diagnosed with autism spectrum disorder fit under two profiles: 'even' and 'reactive'. Furthermore, our analysis shows that temperament can influence the impact of increasing symptom severity on adaptive functioning skills in children with autism spectrum disorder. Study findings highlight the importance of considering temperament when trying to understand the individual differences that influence the development of functioning and developmental outcomes in children with autism spectrum disorder.

Abstract
Individuals with 16p11.2 copy number variant (CNV) show considerable phenotypic heterogeneity. Although autism spectrum disorder (ASD) is reported in approximately 20-23% of individuals with 16p11.2 CNVs, ASD-associated symptoms are observed in those without a clinical ASD diagnosis. Previous work has shown that genetic variation and prenatal and perinatal birth complications influence ASD risk and symptom severity. This study examined the impact of genetic and environmental risk factors on phenotypic heterogeneity among 16p11.2 CNV carriers. Participants included individuals with a 16p11.2 deletion (N = 96) or duplication (N = 77) with exome sequencing from the Simons VIP study. The presence of prenatal factors, perinatal events, additional genetic events, and gender was studied. Regression analyses examined the contribution of each risk factor on ASD symptomatology, cognitive functioning, and adaptive abilities. For deletion carriers, perinatal and additional genetic events were associated with increased ASD symptomatology and decrements in cognitive and adaptive functioning. For duplication carriers, secondary genetic events were associated with greater cognitive impairments. Being female sex was a protective factor for both deletion and duplication carriers. Our findings suggest that ASD-associated risk factors contribute to the variability in symptom presentation in individuals with 16p11.2 CNVs. LAY SUMMARY: There are a wide range of autism spectrum disorder (ASD) symptoms and abilities observed for individuals with genetic changes of the 16p11.2 region. Here, we found perinatal complications contributed to more severe ASD symptoms (deletion carriers) and additional genetic mutations contributed to decreased cognitive abilities (deletion and duplication carriers). A potential protective factor was also observed for females with 16p11.2 variations. Autism Res 2020, 13: 1300-1310. © 2020 International Society for Autism Research, Wiley Periodicals, Inc.

Abstract
Fetal Alcohol Spectrum Disorder (FASD) is one of the leading causes of intellectual disability and learning difficulties around the world. Children with FASD often have extremely low adaptive behavior due to the severity of brain impairment, however there is limited understanding as to the important predictors of adaptive behavior. In a study of 39 children with FASD and 29 comparison children, we found that social cognition (specifically recognizing emotions) was the only significant independent predictor of teacher-rated adaptive functioning even after including IQ, executive functioning, and adverse childhood experiences into the model. In this current study, Māori (Indigenous people of Aotearoa New Zealand) were overrepresented; therefore, the research was supported by a strong partnership with Te Wāhanga Hauora Māori (Māori Health Service). Aotearoa New Zealand's colonized history is recognized and findings are discussed with regard to both the psychological literature and a Te Ao Māori worldview.

Abstract
Adaptive functioning (AF) has been overlooked in the assessment of intellectual disability within the UK Prison Service, primarily because there are no reliable and valid measures of AF suitable for use with prison populations. This position is incompatible with the obligation of Her Majesty's Prison and Probation Service to provide specialist interventions for individuals with intellectual disabilities. This study assessed the psychometric properties of the Adaptive Functioning Assessment Tool (AFAT), a new measure of AF developed for use in prisons. The AFAT was completed on 61 participants (mean age 41, standard deviation 11.8). Internal consistency was tested using Cronbach's α. Construct validity was assessed using linear regression and a Receiver Operator Characteristic analysis. The findings provide evidence to support the AFAT being a reliable and valid measure of AF in prison populations.

Abstract
Between 1% and 3% of persons in general population are estimated to have some degree of intellectual disability. A diagnosis of intellectual disability is based on clinical history, level of intellectual ability and level of adaptive function. Both, the intellectual and adaptive functioning are measured using individually administered standardized tests. More than 75% of persons who have intellectual disability have mild intellectual disability and an underlying specific etiology is less likely to be identified; whereas, in a small percentage of persons with severe intellectual disability, an underlying specific biologic cause is highly likely to be identified. Genetic abnormalities, inborn errors of metabolism and brain malformations are major categories of causes identified in severe to profound intellectual disability. The initial clinical presentation and recognition depends on the severity and underlying cause of intellectual disability. The etiology, severity, cognitive abilities, and adaptive function, vary among persons with intellectual disability and need consideration in developing a treatment plan. The physician plays an essential role in the evaluation, treatment of associated medical conditions and preventive care, and in facilitating and coordinating consultative services and community based care.

Abstract
BACKGROUND Cranial radiotherapy (RT) is associated with risk for cognitive and adaptive dysfunction. Proton RT (PRT) is a technique hypothesized to spare cognition by reducing exposure to nontarget brain tissue. However, little is known regarding functional outcomes in survivors of pediatric brain tumor (BT) treated with PRT. The present study examined the relationship between cognitive and adaptive outcomes in pediatric BT survivors post-PRT. METHODS Survivors treated with either focal (n = 33) or craniospinal irradiation (CSI; n = 37) PRT completed neurocognitive evaluations approximately 5 years post-treatment. Results of intelligence testing and ratings of adaptive functioning are reported. Mediation models examined the relationship among radiation field, cognition, and adaptive functioning. RESULTS The PRT CSI group demonstrated worse cognitive outcomes than the PRT Focal group across each cognitive index (Cohen's d = 0.56-0.70). Parent ratings of adaptive functioning were also worse in the PRT CSI group than the PRT Focal group (Global Adaptive Composite, d = 0.53; conceptual skills, d = 0.67). Cognitive performance fully mediated the relationship between radiation field and adaptive outcomes, while controlling for group differences in tumor histology and RT dose. CONCLUSIONS Focal PRT survivors demonstrated generally positive outcomes with weaknesses in processing speed and aspects of adaptive functioning. CSI exposure was associated with more consistently poor cognitive and adaptive outcomes. The increased risk for adaptive dysfunction in the PRT CSI group appeared due to the effects of CSI on cognition. Efforts to reduce the volume of tissue exposure to RT remain important.

Abstract
UNLABELLED The microbiota-gut-brain axis has been recently recognized as a key modulator of neuropsychiatric health. In this framework, probiotics (recently named "psychobiotics") may modulate brain activity and function, possibly improving the behavioral profiles of children with Autism Spectrum Disorder (ASD). We evaluated the effects of probiotics on autism in a double-blind randomized, placebo-controlled trial of 85 preschoolers with ASD (mean age, 4.2 years; 84% boys). Participants were randomly assigned to probiotics (De Simone Formulation) (n=42) or placebo (n=43) for six months. Sixty-three (74%) children completed the trial. No differences between groups were detected on the primary outcome measure, the Total Autism Diagnostic Observation Schedule - Calibrated Severity Score (ADOS-CSS). An exploratory secondary analysis on subgroups of children with or without Gastrointestinal Symptoms (GI group, n= 30; NGI group, n=55) revealed in the NGI group treated with probiotics a significant decline in ADOS scores as compared to that in the placebo group, with a mean reduction of 0.81 in Total ADOS CSS and of 1.14 in Social-Affect ADOS CSS over six months. In the GI group treated with probiotics we found greater improvements in some GI symptoms, adaptive functioning, and sensory profiles than in the GI group treated with placebo. These results suggest potentially positive effects of probiotics on core autism symptoms in a subset of ASD children independent of the specific intermediation of the probiotic effect on GI symptoms. Further studies are warranted to replicate and extend these promising findings on a wider population with subsets of ASD patients which share targets of intervention on the microbiota-gut-brain axis.

Abstract
BACKGROUND Understanding adaptive functioning profiles in children with Williams syndrome (WS) and autism spectrum disorder (ASD) is critical to inform treatment strategies. However, knowledge in this area is limited and inconclusive. METHOD The current study aimed to characterise the early adaptive profiles of young children with WS (n = 18; Mage = 47 months) and ASD (n = 26; Mage = 45 months) matched on chronological age and developmental age using the Vineland Scales of Adaptive Behavior, Second Edition. RESULTS Results suggest that young children with WS and ASD do not differ on their overall level of adaptive functioning but that those with WS show relative strengths in the Socialisation scale compared with children with ASD. No other subscales differed between groups. Within groups, the WS group showed a profile of Communication, Daily Living Skills and Motor < Socialisation, whereas the ASD group did not evidence differences across subscales. CONCLUSIONS Consideration of the shared and syndrome-specific adaptive profiles provides relevant insight on intervention targets and strategies. Given the shared challenges across the two clinical groups, implications and future directions are discussed.

Abstract
BACKGROUND Survivors of pediatric brain tumor are at risk for adaptive difficulties. The present study examined adaptive functioning in a multiethnic sample of survivors accounting for socioeconomic status, and whether demographic, diagnostic, and/or treatment-related variables predict adaptive outcomes. METHOD Participants included a multiethnic sample of survivors (58 Caucasian, 34 Hispanic, and 22 other non-Caucasian; M age = 14.05 years, SD = 4.33) who were approximately seven years post-treatment. Parents rated adaptive functioning and provided demographic information. Diagnostic and treatment-related information was abstracted from the electronic medical record. RESULTS Parent ratings of adaptive functioning were similar across Caucasian, Hispanic, and other non-Caucasian survivors covarying for family income and primary caregiver education, both of which served as proxies for socioeconomic status. All ethnic groups were rated lower than the normative mean in overall adaptive functioning as well as the specific domains of conceptual, social, and practical skills. Demographic, diagnostic, and treatment-related variables were differentially associated with adaptive functioning in survivors of pediatric brain tumor, though socioeconomic status emerged as a strong significant predictor of adaptive functioning domains. CONCLUSIONS Adaptive outcomes do not differ as a function of ethnicity after accounting for primary caregiver education and family income. Racial and ethnic minorities may be at increased risk for poorer outcomes given their overrepresentation at lower income levels. Assessing demographic and treatment-related variables early on may be helpful in identifying children likely to develop adaptive difficulties.

Abstract
Objective: We aimed to examine the prevalence and severity of psychological distress of women with asthma in both the prenatal and postnatal periods, and to determine whether asthmatic women with and without mental health problems differ in self-management, medications knowledge, and asthma symptoms.Methods: We assessed spirometry performance and asthma symptoms in 120 women (mean age 29.8 years) before 23 weeks gestation, as part of the Breathing for Life Trial (Trial ID: ACTRN12613000202763). Prenatal depression data was obtained from medical records. At 6 weeks postpartum, we assessed general health, self-reported asthma control, depression symptoms (with the Edinburgh Postnatal Depression Scale) and adaptive functioning (with the Achenbach System of Empirically Based Assessment scales).Results: Twenty percent of our sample reported having a current mental health diagnosis, 14% reported currently receiving mental health care, while 47% reported having received mental health care in the past (and may/may not have received a diagnosis). The sample scored high on the Aggressive Behavior, Avoidant Personality, and Attention Deficit/Hyperactivity scales. Poorer self-reported postnatal asthma control was strongly correlated with elevated somatic complaints, externalizing problems, antisocial personality problems, and greater withdrawal. Prenatal spirometry or asthma severity and control were largely not associated with measures of psychopathology.Conclusions: These findings indicate that pregnant women with asthma frequently report issues with psychopathology during the prenatal and postnatal periods, and that the subjective perception of asthma control may be more related to psychopathology than objective asthma measures. However, due to sample bias, these findings are likely to be understated.
