Factor structure of the VABS-3 Comprehensive Parent/Caregiver form in autistic individuals: Poor fit of three-factor and unidimensional models / Ellen WILKINSON in Autism, 28-3 (March 2024)  

Public ISBD [article]  inAutism > 28-3 (March 2024) . - p.616-626 Titre : Factor structure of the VABS-3 Comprehensive Parent/Caregiver form in autistic individuals: Poor fit of three-factor and unidimensional models Type de document : texte imprimé Auteurs : Ellen WILKINSON, Auteur ; Cristan FARMER, Auteur ; Evan M. KLEIMAN, Auteur ; Vanessa H. BAL, Auteur Article en page(s) : p.616-626 Langues : Anglais (eng) Mots-clés : adaptive behavior  autism spectrum disorders  behavioral measurement Index. décimale : PER Périodiques Résumé : The commonly used Vineland Adaptive Behavior Scales (VABS-3) divides adaptive behavior into three domains comprising three subdomains. The validity of this three-factor structure has not been explored in autistic samples, which are often heterogeneous with respect to language and IQ. Furthermore, although there are two comparable forms, Comprehensive Interview Form and Comprehensive Parent/Caregiver Form (a questionnaire), the original validation was based on interview data. Considering the widespread use of the VABS-3 in autism research, and the increased feasibility of online-administered questionnaires, it is necessary to establish the validity of the Parent/Caregiver form in autistic individuals across a range of abilities. This study aimed to investigate the measurement invariance of the VABS-3 Parent/Caregiver form between a minimally verbal group and verbal group of autistic people; however, poor overall fit of the three-factor structure precluded invariance analyses. Subsequent analyses suggested poor fit in both language and age groups, as well as a unidimensional model. The results of the current study suggest that neither the three-factor or unidimensional model fit the VABS-3 Parent/Caregiver Form, thereby cautioning against interpretation of domain or overall adaptive behavior composite scores in autistic individuals and further encouraging careful consideration of administration format. Lay Abstract Adaptive behavior is a broad set of skills needed to function in everyday life. The Vineland Adaptive Behavior Scales (VABS-3) is commonly used to measure adaptive behavior. It divides adaptive behavior into three domains, Communication, Daily Living Skills, and Socialization, each of which are split into subdomains. Analyses of this three-part structure of the first version of VABS used the instrument as an interview, but now it is done as a questionnaire as well. The structure has not been well supported in samples of autistic people, who often have different strengths and challenges in adaptive behavior compared with non-autistic people. Because adaptive behavior is an important concept in autism research and online-administered questionnaires are increasingly common, it is important to ensure the structure of the VABS-3 Comprehensive Parent/Caregiver Form (VABS-3:CPCF; a questionnaire) works well for autistic individuals across a range of abilities. This study aimed to investigate whether VABS-3:CPCF measures adaptive behavior similarly in verbal and minimally verbal autistic people. However, the data didn t fit the structure in the first step of the analysis, so this could not be investigated. The next analyses also found the three-domain structure didn t fit in different age and language groups. In addition, the data didn t fit a structure combining all the domains into 1 (unidimensional). These results suggest that neither the three-factor or unidimensional structure fit the VABS-3:CPCF, cautioning against interpretation of domain or overall adaptive behavior composite scores in autistic individuals and further encouraging careful consideration of administration format.

Measuring subjective quality of life in autistic adults with the PROMIS global-10: Psychometric study and development of an autism-specific scoring method / Zachary J. WILLIAMS in Autism, 27-1 (January 2023)  

Public ISBD [article]  inAutism > 27-1 (January 2023) . - p.145-157 Titre : Measuring subjective quality of life in autistic adults with the PROMIS global-10: Psychometric study and development of an autism-specific scoring method Type de document : texte imprimé Auteurs : Zachary J. WILLIAMS, Auteur ; Carissa J. CASCIO, Auteur ; Tiffany G. WOYNAROSKI, Auteur Article en page(s) : p.145-157 Langues : Anglais (eng) Mots-clés : adults  behavioral measurement  item response theory  mental health  physical health  PROMIS  psychometrics  quality of life  reliability  validity Index. décimale : PER Périodiques Résumé : Quality of life is widely acknowledged as one of the most important outcomes in autism research, but few measures of this construct have been validated for use in autistic people. The goal of the current study was to examine the psychometric properties of the Patient-Reported Outcomes Measurement Information System Global-10, an established self-report measure of health-related quality of life, in a sample of 901 autistic adults (predominantly female and adult-diagnosed) recruited from the Simons Foundation Powering Autism Research for Knowledge cohort. Using an item response theory framework, we performed a comprehensive psychometric evaluation of the Patient-Reported Outcomes Measurement Information System Global-10 in this sample, examining its latent structure, differential item functioning, reliability, and construct validity. After developing an autism-specific measurement model, the Patient-Reported Outcomes Measurement Information System Global-10 demonstrated excellent psychometric properties in the current sample, including excellent model-data fit, high reliability, minimal differential item functioning across subgroups of autistic adults, and an expected pattern of correlations with external variables. Exploratory analyses indicated that lower quality of life was associated with female sex and identified as a sexual/gender minority. A free online score calculator has been created to facilitate the use and interpretation of normed Patient-Reported Outcomes Measurement Information System Global-10 general quality of life latent trait scores for clinical and research applications (available at https://asdmeasures.shinyapps.io/promis_qol). Lay Abstract Quality of Life an outcome that both researchers and autistic advocates agree is extremely important to consider when implementing services, interventions, and supports for autistic people. However, there has been little research on the topic of how quality of life can best be measured in autistic people or whether existing quality of life questionnaires are appropriate for use in the autistic population. This study aimed to validate an established quality of life measure, the Patient-Reported Outcomes Measurement Information System Global-10, in a large sample of autistic adults recruited online. We created a new way to score the Patient-Reported Outcomes Measurement Information System Global-10 scale and generate a œGeneral quality of life  score specific to autistic adults. This new score performed very well in this sample, showing very little measurement error and relating in expected ways to similar constructs, such as physical health and emotional distress. Exploratory analyses found that lower quality of life was associated with female sex and self-identification as a sexual or gender minority (i.e. LGBTQ + identity). These findings suggest that the new Patient-Reported Outcomes Measurement Information System Global-10 quality of life score is a reliable and valid measure of quality of life in autistic adults, although additional studies are necessary to further explore its measurement properties in other subsets of the autistic population, such as individuals with intellectual disabilities. This measure is freely available for use as an outcome in both research and clinical practice, and an online score calculator is available to support the use of this measure in real-world applications.

It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the specific behavioral characteristics of autism was assessed by studying individual ADOS items for 183 children (55 girls) from age 3-to-11 years. Girls decreased in total autism symptom severity (ADOS-CSS) and restricted/repetitive behavior severity (RRB-CSS) across childhood, while boys remained stable in both. Girls showed decreasing-severity trajectories for seven ADOS items and an increasing-trajectory for one item. Boys showed decreasing-severity trajectories for six items and increasing-severity trajectories for three items. Girls with higher ADOS-CSS at age 3 were more likely to decrease in total symptom severity than other girls. Girls in our study mostly improved or remained stable in autism symptom severity and its specific behaviors during childhood, especially behaviors related to being socially engaged and responsive. Boys" symptom change was variable over time and included both improvement and worsening, especially in social behaviors that are key to interaction. Girls with high early severity levels can potentially decrease substantially in severity during childhood.Lay Abstract The severity of overall autism symptoms tend to decrease more in autistic girls than in autistic boys during childhood, but we do not know which specific behaviors drive this difference. We studied how specific behaviors characteristic of autism change for girls and boys across childhood. We found that girls mostly improve or remain stable in the severity level of their autism symptoms and its specific behaviors during childhood. They improved mostly in behaviors related to being socially engaged and responsive to others. Furthermore, we found that it is possible for girls with high early autism symptoms to show major improvement during childhood. Boys improved in some specific behaviors but worsened in others. Boys worsened in some behaviors that are key to engaging in social interactions.

Changes in the severity of autism symptom domains are related to mental health challenges during middle childhood / Einat WAIZBARD-BARTOV in Autism, 28-5 (May 2024)

We evaluated this relationship in 75 autistic children from 6 to 11 years old. Autism symptom severity change was evaluated for total autism symptoms using the autism diagnostic observation schedule calibrated severity score, as well as social-communication symptoms calibrated severity score, and restricted/repetitive behaviors calibrated severity score. Children were grouped based on their symptom severity change patterns. Mental health symptoms (attention-deficit hyperactivity disorder, anxiety, disruptive behavior problems) were assessed via parental interview and questionnaire and compared across the groups. Co-occurring mental health symptoms were more strongly associated with change in social-communication symptom or restricted/repetitive behavior severity than with total autism symptom severity. Two relevant groups were identified. The social-communication symptom-increasing-severity-group (21.3%) had elevated and increasing levels of anxiety, attention-deficit hyperactivity disorder, and disruptive behavior problems compared with children with stable social-communication symptom severity. The restricted/repetitive behavior-decreasing-severity-group (22.7%) had elevated and increasing levels of anxiety; 94% of these children met criteria for an anxiety disorder. Autism symptom severity change during middle childhood is associated with co-occurring mental health symptoms. Children that increase in social-communication symptom severity are also likely to demonstrate greater psychopathology, while decreases in restricted/repetitive behavior severity are associated with higher levels of anxiety. Lay abstract For many autistic children, the severity of their autism symptoms changes during middle childhood. We studied whether these changes are associated with the emergence of other mental health challenges such as anxiety and attention-deficit hyperactivity disorder. Children who had increased social-communication challenges had more anxiety and attention-deficit hyperactivity disorder symptoms and disruptive behavior problems than other children. Children who decreased their restricted and repetitive behaviors, on the contrary, had more anxiety. We discuss why these changes in autism symptoms may lead to increases in other mental health concerns.

One hundered and four toddlers of 16-31 months old (mean = 22) participated in this study. Twenty-two of the toddlers had autism spectrum disorder and 82 had typical development or developmental delay. Toddlers watched video stimuli on a tablet while the built-in camera recorded their head movement. Computer vision analysis measured participants' attention and orienting in response to name calls. Reliability of the computer vision analysis algorithm was tested against a human rater. Differences in behavior were analyzed between the autism spectrum disorder group and the comparison group. Reliability between computer vision analysis and human coding for orienting to name was excellent (intra-class coefficient 0.84, 95% confidence interval 0.67-0.91). Only 8% of toddlers with autism spectrum disorder oriented to name calling on >1 trial, compared to 63% of toddlers in the comparison group (p = 0.002). Mean latency to orient was significantly longer for toddlers with autism spectrum disorder (2.02 vs 1.06 s, p = 0.04). Sensitivity for autism spectrum disorder of atypical orienting was 96% and specificity was 38%. Older toddlers with autism spectrum disorder showed less attention to the videos overall (p = 0.03). Automated coding offers a reliable, quantitative method for detecting atypical social orienting and reduced sustained attention in toddlers with autism spectrum disorder.
