Autism Spectrum Disorder (ASD) is a prevalent neurodevelopmental disorder, and early diagnosis plays a pivotal role in prognosis and management. This study aims to examine the psychometric properties of the Autism Mental Status Exam (AMSE), a tool that shows great promise in terms of clinical utility, within the Turkish population. This study conducted in a cohort of 307 Turkish children aged 17 to 120 months with suspected ASD. Participants underwent a multidisciplinary assessment based on DSM-5 criteria for diagnosis and were categorized into ASD and non-ASD groups. Subsequently, the research team conducted blinded administrations of the AMSE and Childhood Autism Rating Scale (CARS). Additionally, a subset of 61 children underwent retesting for AMSE and CARS after three weeks for temporal stability. The results revealed an optimal cut-off score of 4 for AMSE, yielding sensitivity and specificity rates of 84% and 97%, respectively. Internal consistency, indicated by a Cronbach's alpha of 0.80, was very good. The test-retest reliability, assessed using the Intraclass Correlation Coefficient (ICC), was excellent (ICC = 0.959). The inter-rater reliability also showed excellent agreement (ICC = 0.997). Furthermore, a significant correlation was observed between the AMSE and CARS scores (r = 0.94, p < 0.001). Notably, the AMSE scores were significantly different between the ASD and non-ASD groups (p < 0.001) with a large effect size (Cohen's d = 1.40). The findings of this study underscore the utility of AMSE as a valid and reliable tool for Turkish children with robust psychometric properties.

Autistic trans and gender diverse (TGD) individuals face unique voice and communication challenges compounded by minority stressors, impacting wellbeing and access to care. Speech pathologists are crucial in providing gender-affirming and neurodiversity-affirming support; however, guidance for working with this intersectional population remains limited. This scoping review mapped current knowledge on voice and communication challenges, identifies available supports, and demonstrates the limitations of existing guidance for speech pathologists. This review draws on 40 sources, including 29 peer-reviewed articles, 8 clinical guidelines, 2 books, and 1 position statement, identified through comprehensive searches of databases such as CINAHL, ERIC, Medline, APA PsycINFO, and grey literature in May 2024. Findings indicated that 96.8% of identified challenges pertained to communication, while fewer (3.2%) focused on voice-specific issues. Similarly, supports primarily addressed communication (91.3%), with 8.7% targeting voice needs. Communication challenges included barriers faced by autistic TGD individuals and those interacting with them, including healthcare professionals, peers, and family. Supports were identified as strategies and resources to enhance service delivery and client wellbeing, such as using visual aids or offering multiple communication options. However, significant gaps remain in addressing the unique voice and communication needs of this population, particularly regarding voice dysphoria, camouflaging versus identity disclosure, and communication within healthcare settings. Autistic TGD individuals represent a unique population whose needs are not sufficiently addressed by current guidance. This review highlights significant gaps in research and clinical practice and calls for improved clinical guidelines and specialized training for speech pathologists to enhance care.

Cry analysis is emerging as a promising tool for early autism identification. Acoustic features such as fundamental frequency (F0), cry duration, and phonation have shown potential as early vocal biomarkers. This systematic review and meta-analysis aimed to evaluate the diagnostic value of cry characteristics and the role of Machine Learning (ML) in improving autism screening. A comprehensive search of relevant databases was conducted to identify studies examining acoustic cry features in infants with an elevated likelihood of autism. Inclusion criteria focused on retrospective and prospective studies with clear cry feature extraction methods. A meta-analysis was performed to synthesize findings, particularly focusing on differences in F0, and assessing the role of ML-based cry analysis. The review identified eleven studies with consistent acoustic markers, including F0, phonation, duration, amplitude, and voice quality, as reliable indicators of neurodevelopmental differences associated with autism. ML approaches significantly improved screening precision by capturing non-linear patterns in cry data. The meta-analysis of six studies revealed a trend toward higher F0 in autistic infants, although the pooled effect size was not statistically significant. Methodological heterogeneity and small sample sizes were notable limitations across studies. Cry analysis holds promise as a non-invasive, accessible tool for early autism screening, with ML integration enhancing its diagnostic potential. However, the findings emphasize the need for large-scale, longitudinal studies with standardized methodologies to validate its utility and ensure its applicability across diverse populations. Addressing these gaps could establish cry analysis as a cornerstone of early autism identification.

Human-Animal Interaction (HAI) has been widely adopted as an approach to enhance the well-being of children with ASD, who often experience significant social impairments, emotional dysregulation, and other daily challenges. Given the potential variation of HAI across countries, there is a particular need to explore this phenomenon within different cultural contexts and to illuminate directions for facilitating positive HAI among children with ASD. The purpose of this review is to systematically synthesize the current knowledge of HAI as applied to children with ASD and to discuss possible variations across different cultural contexts. A systematic database search was conducted to synthesize HAI characteristics from existing studies that met the selection criteria. The results highlighted that most of the selected studies (N = 97) were conducted in Europe or the United States. The most common format of HAI identified was animal-assisted intervention, followed by pet ownership. Dogs and horses were the primary animals involved in HAI for children with ASD, while the majority of HAI occurred in home settings and at horse riding or training centres. To conclude, this review provides a more comprehensive lens for understanding the phenomenon of HAI for children with ASD across different countries and discusses cultural variations in terms of the companion animals involved, the formats, and the settings of HAI. It also offers therapeutic insights into the multicultural aspects of HAI, which may shed light on future interventions for children with ASD through HAI in more diverse settings.

Purpose: Wellbeing refers to a person's overall happiness and satisfaction with life. Wellbeing for people with Intellectual and Developmental Disabilities (I/DD) and their families is historically significantly lower compared to the general population. It is important in the context of behavioral health treatment to not only measure the individual who is receiving treatment's overall wellbeing, but also the wellbeing of the family. The purpose of this study was to understand the initial psychometric properties of the Catalight Family Wellbeing Scale.

Methods: The Catalight Family Wellbeing Scale was developed for families who have a child with I/DD. Caregivers of 3106 families who have a child with a diagnosed I/DD, including autism spectrum disorder, completed the scale as part of their onboarding for behavioral health treatment along with three other questionnaires. The psychometric properties including internal reliability and factor structure were completed as well as initial convergent and divergent validity.

Results: Results of the analyses revealed very strong internal reliability and a three-factor structure. Validity analyses revealed a moderate positive relationship with parental self-efficacy and a moderate negative relationship with parental stress. Additionally, the sample population represents an ethnically diverse group with multiple co-occurring diagnosis in addition to I/DD.

Conclusions: The initial psychometric properties of the Catalight Family Wellbeing Scale are positive and support the use of the scale for families who have a child with I/DD across a diverse sample.

Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by difficulties in communication and social-emotional interaction. It is associated with an increase of parental stress and poor family functioning, both of which are harmful for a child's functioning and adaptive behavior. An important source of support to parents are grandparents, especially in traditional populations. One such population is the Bedouin population. The present study tested the association between emotional support from mother and mother-in-law to the adaptive behavior of children with ASD, and whether this relation is serially mediated by family functioning and satisfaction in life as reported by Bedouin mothers of children with ASD. 100 mothers of children with ASD fulfilled a questionnaire about emotional support from their mothers and mother-in-law, family functioning, satisfaction in life and child's adaptive behavior. We found that indeed, family functioning and satisfaction in life serially mediated the relations between emotional support from mother and mother-in-law and child adaptive behavior. These findings indicate that intergenerational solidarity between women can improve not only the functioning of the nuclear family and wife's satisfaction with life, but also, indirectly, the adaptive behavior of a child with ASD. It highlights the importance of women solidarity, especially in traditional society, where women are kept marginal.

Behavior analysts frequently use the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) to assess the language and social skills of children with autism in everyday practice and in research. Despite the widespread use of the VB-MAPP, its psychometric characteristics have not been extensively investigated. To provide information about its convergent validity, we calculated correlations between scores earned by 235 children with autism on the VB-MAPP and the Vineland Adaptive Behavior Scale (VABS), a commonly used assessment with good reliability and validity. We obtained moderate or strong positive correlations between the VB-MAPP Milestones score and VABS Communication, Socialization, and Daily Living Skills subdomains. There was also a strong positive correlation between the VB-MAPP Milestones score and VABS overall raw score. These findings suggest that the VB-MAPP Milestones Assessment measures aspects of social and communicative behavior comparable to those indexed by these VABS subdomains which, like prior findings, supports the use of the Milestones Assessment. No significant relationship was observed between the VB-MAPP Barriers score and the VABS Internalizing, Externalizing, or overall Maladaptive Behavior scores. These findings, like prior findings, question the value of the VB-MAPP's Barriers Assessment as a measure of maladaptive behavior.

The purpose of this study was to understand caregivers' experience of participating in a caregiver-mediated in-home feeding intervention, the Engaged Eaters Program, for their young autistic child. This qualitative study utilized a thematic approach to analyze post-intervention semi-structured interviews with thirteen mothers of autistic children between the ages of 2 to 7 years after they participated in the intervention. Interview questions focused on the child and family experience, what worked well, what could be improved, and how the intervention integrated into family routines. Four major themes were identified: In-Home Intervention, Parent Skill and Knowledge, Increased Social Participation, and Parent Responsibilities and Challenges. Sub-themes provided descriptions of learning practical tools to support their child, increasing self-efficacy, and impacts on family life. Mothers described an increase in tangible skills that were easily practiced in the home environment that improved their confidence and self-efficacy in feeding their children. They also described how participation did require more work and time commitment for them beyond their regular responsibilities. The caregiver experience is essential to understand for intervention effectiveness while simultaneously addressing child, caregiver, and family needs. By focusing on the mothers' experiences, individualized needs, and self-efficacy, we were able to better understand how integrating an intervention into the family context and daily routines may be beneficial for the whole family.

The Anxiety Scale for Autism-Adults (ASA-A) captures the autistic anxiety experience, but we do not know whether it is structurally equivalent for men and women, or non-autistic people. Measurement invariance analysis considered gender and diagnostic status (342 cis-gender autistic men (N = 105) and women (N = 237), 316 cis-gender non-autistic men (N = 104) and women (N = 212)). Strict invariance was achieved between autistic men and women and between non-autistic men and women, but the ASA-A structure is quantitatively different in autistic compared to non-autistic adults. Therefore, this tool cannot be used to directly compare anxiety between these groups. Autistic women scored significantly higher on the ASA-A than autistic men and Uncertainty was the highest scoring factor for autistic participants. Future research should include alternative gender identities.

In studies that assess perceptions of autistic people by non-autistic people, researchers often ask participants to review vignettes depicting fictional autistic characters. However, few studies have investigated whether non-autistic peers accurately identify these hypothetical individuals as being on the autism spectrum. Accurately ascribing autism as a cause of depicted behaviors likely influences perceptions about autistic peers. In this study, 469 college students (M_age = 18.62; 79.3% female) ascribed cause(s) of an autistic peers' behaviors as depicted in a written vignette. We reviewed and categorized open-ended responses into 16 categories. Non-autistic college students primarily attributed an autistic vignette character's behavior to non-autistic origins. The most commonly ascribed causes of behavior were: attention-deficit/hyperactivity disorder (55.4%), inattention symptoms (20.9%), autism (12.8%), generalized anxiety disorder (11.7%), hyperactivity (11.3%), an unspecified diagnosis (10.7%), an environmental influence (9.6), anxiety or insecurity (8.3%), irritability or anger or annoyance (6.0%), social anxiety disorder (5.3%), and learning disorder (5.1%). Additional ascribed causes include other mental health diagnoses; environmental stressors; and cognitive, emotional, behavioral, biological, or personality characteristics/etiologies. Non-autistic young adults may not always recognize their autistic peers as autistic, which may affect acceptance and inclusion. Future anti-stigma interventions should assess the impact of helping non-autistic peers to accurately identify and better understand behaviors associated with autism. Additionally, autism-focused researchers using vignettes should assess participants' awareness of the character as autistic and interpret their findings with this in mind.
