Development and validation of an item response theory-based Social Responsiveness Scale short form / Alexandra STURM in Journal of Child Psychology and Psychiatry, 58-9 (September 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-9 (September 2017) . - p.1053-1061 Titre : Development and validation of an item response theory-based Social Responsiveness Scale short form Type de document : Texte imprimé et/ou numérique Auteurs : Alexandra STURM, Auteur ; Megan KUHFELD, Auteur ; Connie KASARI, Auteur ; James T. MCCRACKEN, Auteur Article en page(s) : p.1053-1061 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  behavioral measures Index. décimale : PER Périodiques Résumé : Background Research and practice in autism spectrum disorder (ASD) rely on quantitative measures, such as the Social Responsiveness Scale (SRS), for characterization and diagnosis. Like many ASD diagnostic measures, SRS scores are influenced by factors unrelated to ASD core features. This study further interrogates the psychometric properties of the SRS using item response theory (IRT), and demonstrates a strategy to create a psychometrically sound short form by applying IRT results. Methods Social Responsiveness Scale analyses were conducted on a large sample (N = 21,426) of youth from four ASD databases. Items were subjected to item factor analyses and evaluation of item bias by gender, age, expressive language level, behavior problems, and nonverbal IQ. Results Item selection based on item psychometric properties, DIF analyses, and substantive validity produced a reduced item SRS short form that was unidimensional in structure, highly reliable (? = .96), and free of gender, age, expressive language, behavior problems, and nonverbal IQ influence. The short form also showed strong relationships with established measures of autism symptom severity (ADOS, ADI-R, Vineland). Degree of association between all measures varied as a function of expressive language. Conclusions Results identified specific SRS items that are more vulnerable to non-ASD-related traits. The resultant 16-item SRS short form may possess superior psychometric properties compared to the original scale and emerge as a more precise measure of ASD core symptom severity, facilitating research and practice. Future research using IRT is needed to further refine existing measures of autism symptomatology.

Discrimination and Harassment Experiences of Autistic College Students and Their Neurotypical Peers: Risk and Protective Factors / Lauren BACZEWSKI ; Maria PIZZANO ; Connie KASARI ; Alexandra STURM in Journal of Autism and Developmental Disorders, 53-12 (December 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-12 (December 2023) . - p.4521-4534 Titre : Discrimination and Harassment Experiences of Autistic College Students and Their Neurotypical Peers: Risk and Protective Factors Type de document : Texte imprimé et/ou numérique Auteurs : Lauren BACZEWSKI, Auteur ; Maria PIZZANO, Auteur ; Connie KASARI, Auteur ; Alexandra STURM, Auteur Article en page(s) : p.4521-4534 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examines autistic and non-autistic college students' experiences of discrimination and harassment and identifies protective and risk factors. A nationwide survey was used to match autistic students (N=290) and non-autistic students (N=290) on co-occurring diagnoses and demographic characteristics. Multiple regression and interaction analysis revealed that faculty support was protective against discrimination and harassment regardless of autism status. Habits of mind was particularly protective for autistic students against harassment. Any student who engaged in school-facilitated events was more likely to experience discrimination and harassment, but the risk was heightened for autistic students. Findings highlight the importance of faculty support in fostering positive interpersonal experiences on campus, and demonstrate the need to address deeper college campus issues with respect to neurodiversity.

Measurement matters: A commentary on the state of the science on patient reported outcome measures (PROMs) in autism research / Hillary K. SCHILTZ in Autism Research, 17-4 (April 2024)  

Public ISBD [article]  inAutism Research > 17-4 (April 2024) . - p.690-701 Titre : Measurement matters: A commentary on the state of the science on patient reported outcome measures (PROMs) in autism research Type de document : Texte imprimé et/ou numérique Auteurs : Hillary K.

ROSENAU, Auteur ; Christina NICOLAIDIS, Auteur ; Alexandra STURM, Auteur ; Catherine LORD, Auteur ; Autism PROMNET, Auteur Article en page(s) : p.690-701 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract High quality science relies upon psychometrically valid and reliable measurement, yet very few Patient Reported Outcome Measures (PROMs) have been developed or thoroughly validated for use with autistic individuals. The present commentary summarizes the current state of autism PROM science, based on discussion at the Special Interest Group (SIG) at the 2022 International Society for Autism Research (INSAR) Annual Meeting and collective expertise of the authors. First, we identify current issues in autism PROM research including content and construct operationalization, informant-structure, measure accessibility, and measure validation and generalization. We then enumerate barriers to conducting and disseminating this research, such as a lack of guidance, concerns regarding funding and time, lack of accessible training and professionals with psychometric skills, difficulties collecting large representative samples, and challenges with dissemination. Lastly, we offer future priorities and resources to improve PROMs in autism research including a need to continue to evaluate and develop PROMs for autistic people using robust methods, to prioritize diverse and representative samples, to expand the breadth of psychometric properties and techniques, and to consider developing field specific guidelines. We remain extremely optimistic about the future directions of this area of autism research. This work is well positioned to have an immense, positive impact on our scientific understanding of autism and the everyday lives of autistic people and their families.

Predictors of Sexual Victimization Among Autistic and Non-Autistic College Students / Connie KASARI ; Alexandra STURM in Journal of Autism and Developmental Disorders, 54-9 (September 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-9 (September 2024) . - p.3467-3477 Titre : Predictors of Sexual Victimization Among Autistic and Non-Autistic College Students Type de document : Texte imprimé et/ou numérique Auteurs : Connie KASARI, Auteur ; Alexandra STURM, Auteur Article en page(s) : p.3467-3477 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Purpose. This study examined predictors of sexual victimization among autistic and non-autistic college students. Specifically, we aimed to determine whether autistic students are more likely than non-autistic students to experience unwanted sexual contact and sexual assault, controlling for co-occurring diagnoses. We also aimed to determine whether students with other disabilities, specifically ADHD, learning disability (LD), and psychological disorders, are more likely than students without these disabilities to experience unwanted sexual contact and sexual assault. Methods. Autistic students (n=270) and non-autistic students (n=270) who had participated in a nationwide survey were matched on demographic characteristics and co-occurring diagnoses. Logistic regression analyses were conducted to address the research questions and evaluate predictors of unwanted sexual contact and sexual assault. Results. Autistic students were as likely as non-autistic students to have experienced unwanted sexual contact and sexual assault, controlling for co-occurring diagnoses. Regardless of autism diagnostic status, students with ADHD were more likely than students without ADHD to have experienced unwanted sexual contact and sexual assault. Conclusions. Although autism diagnostic status was not a significant predictor of unwanted sexual contact or sexual assault, other factors associated with increased risk of sexual victimization, such as co-occurring ADHD, are likely to be found in autistic populations. This study highlights the importance of educational, social, and institutional supports to decrease sexual victimization among college students with neurodevelopmental disabilities.
