The Association of the Broader Autism Phenotype with Emotion-Related Behaviors in Mothers of Children With and Without Autism Spectrum Traits

Exploring autistic traits in parents of autistic children: a pilot study on the broader autism phenotype

Background

Biological parents of autistic children often exhibit characteristics associated with the broader autism phenotype (BAP), a subclinical expression of autism-related traits. While BAP traits are known to be prevalent among first-degree relatives of autistic individuals, the relationship between parental traits and children's characteristics remains under-explored.

Objectives

This pilot study examines the presence and extent of BAP traits in an Italian sample of both biological mothers and fathers of autistic children, exploring also the correlations between parental BAP traits and children's autistic traits.

Methods

Seventy-six autistic children (ages 4-11) and their biological parents were recruited for the study. Parental and child traits were evaluated using the Autism Quotient (AQ) and the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2).

Results

Of the recruited sample of parents, 29% fell within the BAP, with 12% of fathers and 17% of mothers meeting the criteria. A significant difference was found in AQ scores between fathers and mothers, with fathers scoring higher on average. Fathers' AQ scores were significantly correlated with their children's AQ scores, while no significant correlation was observed between mothers' AQ scores and children's scores. Additionally, children's AQ scores correlated significantly with all Vineland Adaptive Behavior Scale (VABS) subscales but not with ADOS scores.

Conclusions

This study highlights the significance of parental BAP traits in relation to autism characteristics in children. The findings suggest that paternal BAP traits, in particular, may have a stronger association with child characteristics. Understanding these associations may contribute to refining psycho-educational strategies tailored to the specific traits of parents, ultimately enhancing intervention approaches.

Caregiver report of infant behavior associated with autism likelihood in first year of life

BACKGROUND

Identification of prodromal indicators of autism in infancy has the potential to identify behaviors relevant to early autism screening.

METHODS

We report on data from a prospective general population birth cohort with maternal reported measures at 9 and 12 months: the Survey of Well-Being of Young Children (SWYC; general developmental surveillance) and the First Year Inventory-Lite v3.1b (FYI-Lite; autism specific parent report research tool). Mothers completed the surveys and the Broad Autism Phenotype Questionnaire (BAPQ), a self-report measure of subclinical features of autism.

RESULTS

In this sample of 332 infants (168 males), maternal-reported infant developmental milestones and behavioral indicators of difficult temperament, poor adaptability, and sleep problems at 9 months (SWYC) and maternal self-reported subclinical autism characteristics (BAPQ) were correlated with maternal-reported autism-related behaviors on the FYI-Lite at 12 months. Regression models revealed significant unique associations between infant temperament, developmental milestones, and FYI-Lite scores while controlling for significant effects of maternal BAPQ scores and education.

CONCLUSIONS

Maternal report of infant temperament and developmental milestones at 9 months were associated with maternal-report early indicators of autism likelihood at 12 months in a general birth cohort. Follow up of this cohort is needed to determine associations with formal diagnostic outcomes.

IMPACT

Identifying scalable measures of infant behaviors in general and specific to autism may help identify targets of intervention for infants in the first year of life. This study aims to contribute to improved first-year surveillance by assessing potential early autism indicators in a prospective general birth cohort, whereas other observational studies utilize enriched risk cohorts (e.g., infant siblings of autistic children). Preliminary findings of this cohort revealed that a maternal report of 9-month temperament significantly predicted higher scores on a maternal report 12-month autism screener and indicated the importance of considering maternal self-reported subclinical autism characteristics when interpreting parent report screeners.

Evaluative contexts facilitate implicit mentalizing: relation to the broader autism phenotype and mental health

One promising account for autism is implicit mentalizing difficulties. However, this account and even the existence of implicit mentalizing have been challenged because the replication results are mixed. Those unsuccessful replications may be due to the task contexts not being sufficiently evaluative. Therefore, the current study developed a more evaluative paradigm by implementing a prompt question. This was assessed in 60 non-autistic adults and compared with a non-prompt version. Additionally, parents of autistic children are thought to show a genetic liability to autistic traits and cognition and often report mental health problems, but the broader autism phenotype (BAP) is an under-researched area. Thus, we also aimed to compare 33 BAP and 26 non-BAP mothers on mentalizing abilities, autistic traits, compensation and mental health. Our results revealed that more evaluative contexts can facilitate implicit mentalizing in BAP and non-BAP populations, and thus improve task reliability and replicability. Surprisingly, BAP mothers showed better implicit mentalizing but worse mental health than non-BAP mothers, which indicates the heterogeneity in the broader autism phenotype and the need to promote BAP mothers' psychological resilience. The findings underscore the importance of contexts for implicit mentalizing and the need to profile mentalizing and mental health in BAP parents.

Socioeconomic disadvantage and parental mood/affective problems links negative parenting and executive dysfunction in children born very preterm

Poverty increases the risk of poorer executive function (EF) in children born full-term (FT). Stressors associated with poverty, including variability in parenting behavior, may explain links between poverty and poorer EF, but this remains unclear for children born very preterm (VPT). We examine socioeconomic and parental psychosocial adversity on parenting behavior, and whether these factors independently or jointly influence EF in children born VPT. At age five years, 154 children (VPT = 88, FT = 66) completed parent-child interaction and EF tasks. Parental sensitivity, intrusiveness, cognitive stimulation, and positive and negative regard were coded with the Parent-Child Interaction Rating Scale. Socioeconomic adversity spanned maternal demographic stressors, Income-to-Needs ratio, and Area Deprivation Index. Parents completed measures of depression, anxiety, inattention/hyperactivity, parenting stress, and social-communication interaction (SCI) problems. Parental SCI problems were associated with parenting behavior in parents of children born VPT, whereas socioeconomic adversity was significant in parents of FT children. Negative parenting behaviors, but not positive parenting behaviors, were related to child EF. This association was explained by parental depression/anxiety symptoms and socioeconomic adversity. Results persisted after adjustment for parent and child IQ. Findings may inform research on dyadic interventions that embed treatment for parental mood/affective symptoms and SCI problems to improve childhood EF.

Brief report: The impact of the broad autism phenotype on parent perception of autism symptoms in their children with and without autism spectrum disorder compared to teachers

BACKGROUND

Evaluation of children with autism spectrum disorder (ASD) includes caregiver-reported rating scales of symptom presentation. The extent to which a broad autism phenotype (BAP) in parents of children with ASD might impact their endorsement of autism symptoms in their children with and without ASD has not been well evaluated.

AIMS

This study analyzed whether varying degrees of parental BAP were associated with reported autism symptoms in offspring with and without ASD.

METHODS AND PROCEDURES

We used the Broad Autism Phenotype Questionnaire as a measure of BAP in parents and parent- and teacher-report on the Social Responsiveness Scale (SRS) to assess autism symptoms in children with ASD and their typically developing (TD) siblings (N = 5714). We assessed the relationship between parental BAP and parent-teacher discordance. We compared teacher reports of autism symptoms in children with varying degrees of BAP exposure.

OUTCOMES AND RESULTS

Mothers with higher levels of BAP over-reported autism symptoms in their children (compared to teachers) than mothers with lower BAP. TD children from parents with greater BAP displayed more autism symptoms than children from households with less BAP.

CONCLUSIONS AND IMPLICATIONS

BAP is associated with parent report of autism symptoms when compared to teacher report. For children with ASD, it is possible that differences in ratings reflect parent perception and not autism symptomatology; whereas, TD children from households with higher levels of BAP exposure showed more phenotypic autism symptom presentation on teacher-completed measures. Researchers and clinicians should consider BAP when interpreting caregiver and teacher reports.

An Initial Pilot Study Examining Child Social Skills, Caregiver Styles, and Family Functioning in the PEERS® for Preschoolers Program for Young Autistic Children and their Caregivers

BACKGROUND

Social impairments characteristic of autism spectrum disorder (ASD) are evident in early childhood and worsen as the child matures. Though many interventions for young children exist, few specifically target social skills and involve caregivers.

AIMS

This pilot study examined PEERS® for Preschoolers, focusing on temporal change in child social skills, caregiver style, and family functioning in the context of a caregiver-assisted social skills intervention. This extension of the PEERS® program builds on the success of the intervention for older children, presenting skills in a developmentally appropriate manner to young autistic children and their caregivers.

METHODS AND PROCEDURES

The present pilot study used a non-concurrent multiple baseline design to examine the above variables with 15 autistic children (Mage = 4.87, SD = 1.25; 11 boys). Children and caregivers participated in PEERS® for Preschoolers groups, with each group randomly assigned three different baseline periods (1.5, 2, or 2.5 weeks) before beginning.

OUTCOMES AND RESULTS

Simulation Modeling Analysis (SMA) revealed concurrent improvements in social and caregiving skills, with subsequent changes in family functioning occurring over the course of this 16-session intervention.

CONCLUSIONS AND IMPLICATIONS

Future research will need to examine mechanisms of change in PEERS® for Preschoolers for children and caregivers.

WHAT THIS PAPER ADDS

There is a dearth of research that specifically examines social skills interventions for young autistic children that incorporates caregivers and examines family functioning as well. This paper is one of the first to evaluate the PEERS® for Preschoolers (P4P) intervention by: 1) exploring changes in child social skills, caregiver efficacy, and family functioning, and 2) analyzing the sequence of improvements in the aforementioned variables to measure systematic change. This pilot study presents results using appropriate methodology for a small sample size of children and caregivers. Results suggested concurrent improvements in social and caregiving skills and subsequent changes in family functioning. These can be built upon for further research on the PEERS® for Preschoolers intervention. This study supports PEERS® for Preschoolers as a feasible intervention that likely contributes to improvements for the child, caregiver in their relationship with their child and parenting styles in general, as well as functioning of the entire family. In sum, this work is essential to furthering the provision of a much needed service of social skills interventions for young autistic children.
