Characterization of dyadic interaction features between fathers and mothers playing with their autistic children.

BACKGROUND: Socio-communicative difficulties are a core symptom of autism that deeply impact interaction with others. Despite that, research on bidirectional caregiver-child interaction variables has been notably scant and predominantly focused on autistic children's interactive differences and the consequences on parenting behaviors. AIM: The study aimed to assess parent-child interaction in the context of autism through observational validated instruments that consider qualitative and structural features in a complementary way to obtain a comprehensive characterization of the exchange within the dyad. METHODS AND PROCEDURES: This study involved 56 paired parent-child dyads of 28 autistic children (mean age = 38.60 months, sd = 9.50) playing with their mothers and their fathers for 10 min. The video-recorded sessions were coded through the Emotional Availability Scales (EAS) and the Interpersonal Synchrony (IS) coding system. OUTCOMES AND RESULTS: Fathers and mothers do not show significant differences in ISexcept for mother widenings, which are more frequent and successful, and in Emotional Availability. Further, dyads present moderate levels of Emotional Availability, indicating that parents may struggle with structuring, sensitivity, and interactive abilities with their autistic children, which in turn present low levels of responsiveness and involvement. Further, we explored an association between IS and EA characteristics. CONCLUSION AND IMPLICATIONS: This study suggests the need for interventions to target interaction considering both caregivers, ultimately targeting both interaction structure and affect features. Research that includes fathers fosters strategies for individualization and treatment optimization.

Promoting emotional and behavioral interventions in ASD treatment: Evidence from EPIGRAM, A naturalistic, prospective and longitudinal study.

BACKGROUND: Prognostic factors from naturalistic treatment studies of children with Autism Spectrum Disorder (ASD) remain largely unknown. We aimed to identify baseline and treatment-related prognostic predictors at 1-year follow-up after Integrative Care Practices (ICPs). METHODS: Eighty-nine preschool children with severe ASD were given ICP combining nine therapeutic workshops based on children's needs. Participants were assessed at baseline and during 12 months follow-up with the Psycho-educational Profile-3-R, Children Autism Rating Scale, Parental Global Impression, and the Autistic Behaviors Scale. We assessed prognostic predictors using multivariable regression models and explored treatment ingredients influencing outcome using Classification and Regression Trees (CART). RESULTS: Multivariable models showed that being a child from first generation immigrant parents predicted increased maladaptive behaviors, whereas play activities had an opposite effect; severity of ASD symptoms and impaired cognitive functions predicted worse autism severity at follow-up; and lower play activities predicted worse parent impression. Regarding treatment effects, more emotion/behavioral interventions predicted better outcomes, and more communication interventions predicted lower autism severity, whereas more education and cognitive interventions had an opposite effect. CART confirmed that more hours of intervention in the emotion/behavioral domain helped classifying cases with better outcomes. More parental support was associated with decreased maladaptive behaviors. Sensorimotor and education interventions also significantly contributed to classifying cases according to outcomes but defined subgroups with opposite prognosis. CONCLUSION: Children who exhibited the best prognosis following ICPs had less autism severity, better cognition, and non-immigrant parents at baseline. Emotion/behavior interventions appeared key across all outcomes and should be promoted.

Child-therapist interaction features impact Autism treatment response trajectories.

BACKGROUND: Identifying mechanisms of change in Autism treatment may help explain response variability and maximize efficacy. For this, the child-therapist interaction could have a key role as stressed by developmental models of intervention, but still remains under-investigated. AIMS: The longitudinal study of treatment response trajectories considering both baseline and child-therapist interaction features by means of predictive modeling. METHODS AND PROCEDURES: N = 25 preschool children were monitored for one year during Naturalistic Developmental Behavioral Intervention. N = 100 video-recorded sessions were annotated with an observational coding system at four time points, to extract quantitative interaction features. OUTCOMES AND RESULTS: Baseline and interaction variables were combined to predict response trajectories at one year, and achieved the best predictive performance. The baseline developmental gap, therapist's efficacy in child engagement, respecting children's timing after fast behavioral synchronization, and modulating the interplay to prevent child withdrawal emerged as key factors. Further, changes in interaction patterns in the early phase of the intervention were predictive of the overall response to treatment. CONCLUSIONS AND IMPLICATIONS: Clinical implications are discussed, stressing the importance of promoting emotional self-regulation during intervention and the possible relevance of the first period of intervention for later response.

Play with Me: How Fathers and Mothers Play with Their Preschoolers with Autism.

(1) Background: Children can develop cognitive and social skills during play. Most research has focused on mothers, but the paternal features in interaction with children with autism spectrum disorder (ASD) are mainly unexplored. This study aimed to compare fathers' and mothers' interactive behaviors with their children with ASD to identify similarities and differences during playful exchanges. (2) Methods: A total of 72 mothers and 72 fathers of paired children with ASD (chronological age: M = 44.61 months; SD = 13.37) took part in this study. Data were collected during 10 min of video-recorded semi-structured interactions with mothers and fathers separately in interaction with their children. (3) Results: Mothers showed more symbolic play (W = 3537; p < 0.001) than fathers, who displayed higher levels of exploratory play (t(139.44) = −2.52; p = 0.013) compared to mothers. However, child cognitive functioning impacts maternal play but not the father's play characteristics. (4) Conclusions: Highlighting mother−child and father−child features may have important service delivery implications for implementing personalized parental-based interventions based on the strengths and weaknesses of both caregivers in a complementary system.

Interpersonal synchrony: Interaction variables and gender differences in preschoolers with ASD.

Background: Females with ASD tend to be under-recognized as they might present a different symptom manifestation, better social abilities, and masking behaviors. Since the main limitation of current literature on gender differences is represented by focusing on broad constructs, research needs to prioritize narrower constructs related to the subdomains of social abilities. Hence, the aim of this work was to explore gender differences in Interpersonal Synchrony of children with ASD. Method: N = 51 psychologist-child dyads, 25 females and 26 males participated in the study. An Observational Coding Scheme to study interaction features was applied to video-recorded sessions of the ADOS-2 administration. Results: Females presented more synchronous behaviors with shorter latencies. Their interplays were longer, more complex, more engaging and most frequently adequately concluded with respect to males. The complexity of interchanges, their total duration and the proportion of exchanges adequately terminated correlated with the Social Affect score, Personal-Social, and Language Quotients in females, but not in males. The success rate of psychologist proposals correlated with Language Quotient in both males and females. The number of exchanges positively correlated with the Performance Quotient in males. Despite females being significantly older than males, age-related differences did not emerge. Conclusions: Our findings suggest the importance of studying gender differences with respect to interaction variables. Females may present better IS abilities which, in turn, may promote social and language development. Further, our results suggested that successful interactions seem to rely more on social abilities in females, while males appeared to rely more on performance skills.

Father-Child Interactions in Preschool Children with ASD: A Systematic Review.

Studies on parental interaction in the context of ASD has mainly focused on mothers, even if fathers and their children seem to form close and supportive relationships that may have unique effects on child development. Given the impact of ASD symptoms on a child's ability to interact with significant others, recent findings strengthen the importance of including caregivers during treatment to guarantee a better adaptation to the child's impairments. Despite this, fathers are scarcely involved, and interventions seem to not be tailored to their interactive characteristics and needs. For this reason, a systematic review was conducted to investigate fathers and children with ASD behaviors during interaction. This review found 12 observational studies that identified social, cognitive, and affective interactive modalities in father-child dyads through three psychology-focused journal databases: PubMed, PsycINFO and Scopus. The significant variation in both sample size and in the measures used to assess dyadic outcomes limits the ability of this work to make robust recommendations for intervention. Despite this, the results revealed characteristic behaviors of this dyad that consequently allow specific targets to be worked on during intervention. In fact, from fathers' individual strengths and weaknesses, it is possible to implement interventions that are complementary with maternal characteristics from the perspective of personalized and optimized treatment.

Quantifying the Child-Therapist Interaction in ASD Intervention: An Observational Coding System.

BACKGROUND: Observational research plays an important part in developmental research due to its noninvasiveness. However, it has been hardly applied to investigate efficacy of the child-therapist interaction in the context of naturalistic developmental behavioral interventions (NDBI). In particular, the characteristics of child-therapist interplay are thought to have a significant impact in NDBIs in children with autism spectrum disorder (ASD). Quantitative approaches may help to identify the key features of interaction during therapy and could be translated as instruments to monitor early interventions. METHODS: n = 24 children with autism spectrum disorder (ASD) were monitored from the time of the diagnosis (T0) and after about one year of early intervention (T1). A novel observational coding system was applied to video recorded sessions of intervention to extract quantitative behavioral descriptors. We explored the coding scheme reliability together with its convergent and predictive validity. Further, we applied computational techniques to investigate changes and associations between interaction profiles and developmental outcomes. RESULTS: Significant changes in interaction variables emerged with time, suggesting that a favorable outcome is associated with interactions characterized by increased synchrony, better therapist's strategies to successfully engage the child and scaffold longer, more complex and engaging interchanges. Interestingly, data models linked interaction profiles, outcome measures and response trajectories. CONCLUSION: Current research stresses the need for process measures to understand the hows and the whys of ASD early intervention. Combining observational techniques with computational approaches may help in explaining interindividual variability. Further, it could disclose successful features of interaction associated with better response trajectories or to different ASD behavioral phenotypes that could require specific dyadic modalities.

Paternal speech directed to young children with Autism Spectrum Disorders and typical development.

BACKGROUND: Few studies have investigated the characteristics of father language directed to typically developing children (TD), and father speech directed to children with Autism Spectrum Disorders (ASD) is largely under investigated. Considering the importance of involving fathers of children with ASD in research and clinical practice, the main purpose of this study was to investigate paternal speech directed to children with ASD compared to that of fathers of TD children. METHODS: To this aim, we coded multiple functional aspects of speech during 10-min naturalistic dyadic play interactions between fathers and their preschool children with ASD (n = 20) and with TD (n = 20). RESULTS: Results showed that fathers of children with ASD displayed a peculiar child-directed language that seems to reflect the effort to provide enhanced scaffolding and reduced demands while sustaining a challenging social interaction. Specifically, fathers of children with ASD used more descriptions, fewer questions in general but more questions about child internal states. Moreover, fathers adapted aspects of their information-salient speech to the severity of child impairments. CONCLUSIONS: Our findings support the importance to include fathers in early developmental intervention programs for children with ASD, by underlying fathers' spontaneous adaptation to their children's needs.

Emotional Availability and Play in Mother-Child Dyads with ASD: Changes during a Parental Based Intervention.

(1) Background: Parental involvement during intervention with children with Autism Spectrum Disorder (ASD) has been demonstrated to be fundamental for children's developmental outcomes. However, most research focused on child gains especially considering cognitive functioning and symptoms severity, whereas parental and dyadic changes during intervention need further investigation. (2) Methods: 29 mothers in interaction with their preschool children with ASD were analyzed through two standardized behavioral and observational measures to evaluate the dyadic Emotional Availability (EA) and play skills before (T1) and after (T2) a parental-based intervention. (3) Results: Results revealed mothers increased affective quality and major awareness in understanding the signals produced by the child, that in turn was more responsive, involving also using more complex play strategies. Interestingly, the role of specific factors able to predict parental characteristics was investigated, pointing out the important contribution of mothers' perceptions of having a difficult child and child language communicative abilities. (4) Conclusions: the study enhances knowledge about child and caregiver variables that impact on dyadic outcomes, identifying important target areas to be addressed during intervention. Further, our results suggest that a parental-based intervention supports and facilitates improvements in both children's and caregivers' affective quality and cognitive abilities.

Changes in Developmental Trajectories of Preschool Children with Autism Spectrum Disorder during Parental Based Intensive Intervention.

(1) Background: Research highlights the positive effects of early intensive intervention with parent and school involvement for preschool children with Autism Spectrum Disorder (ASD) on general developmental outcomes and social skills in randomized controlled trials. However, given the inter-individual variability in the response to treatment, it is necessary to investigate intervention effects in terms of mediators and moderators in order to explain variability and to highlight mechanisms of change. (2) Methods: 25 children in the experimental group were exposed to early intensive intervention and 14 children in the control group were subjected to "as usual" intervention. The initial assessment was obtained at the time of diagnosis (T1) and the follow-up assessment was conducted after 15 months of intervention (T2) in both groups. (3) Results: Participants in the experimental group achieved more prominent gains in both cognitive and socio-interactive skills. The role of specific factors able to predict general quotient and language quotient after intervention were investigated, pointing out the contribution of personal-social and performance abilities. (4) Conclusions: The findings support the importance of parental involvement in targeting ASD core symptoms. Further, results informed our understanding of early predictors in order to identify specific elements to be targeted in the individualized intervention design.

PTRcombiner: mining combinatorial regulation of gene expression from post-transcriptional interaction maps.

BACKGROUND: The progress in mapping RNA-protein and RNA-RNA interactions at the transcriptome-wide level paves the way to decipher possible combinatorial patterns embedded in post-transcriptional regulation of gene expression. RESULTS: Here we propose an innovative computational tool to extract clusters of mRNA trans-acting co-regulators (RNA binding proteins and non-coding RNAs) from pairwise interaction annotations. In addition the tool allows to analyze the binding site similarity of co-regulators belonging to the same cluster, given their positional binding information. The tool has been tested on experimental collections of human and yeast interactions, identifying modules that coordinate functionally related messages. CONCLUSIONS: This tool is an original attempt to uncover combinatorial patterns using all the post-transcriptional interaction data available so far.
