Preliminary analysis of an instructional alternative to exclusionary discipline
37 pagesDecades of research have shown that exclusionary discipline practices are not only ineffective
for changing student behavior, they lead to worse social, behavioral, and academic outcomes for
students. This article explores the findings from a pilot study of the Inclusive Skill-Building
Learning Approach (ISLA), an instructional alternative to exclusionary discipline practices. The
purposes of ISLA are to improve student social and behavioral problem-solving, teacher and
administrator practices, and student-teacher relationships while also reducing lost instructional
time for student excluded from their learning environment. Results from the pilot indicated that
implementation of ISLA was associated with reductions in exclusionary discipline practices
(Cohen’s h effect sizes ranged from .06 to .18 across schools and outcomes), and a substantial
decrease in instructional minutes lost (~ 92%). Educational staff also reported favorable
impressions of the intervention. Practical and conceptual implications, limitations of this study,
and directions for future research are further discussed.The research reported here was supported by the Fairway Fund, a College of Education Faculty

Improving a Universal Intervention for Reducing Exclusionary Discipline Practices using Student and Teacher Guidance
46 pagesExclusionary discipline practices have a direct negative impact on individual students, schools, and society at large. To improve equity and cultural responsivity, active efforts to assess the contextual fit of effective strategies are necessary. The following study describes the Inclusive Skill-building Learning Approach (ISLA), an intervention designed to support school staff in carrying out preventative strategies and outlines instructional responses for educators and office staff. Additionally, an iterative approach to inform changes was used as part of the development process of ISLA. This paper aims to capture and incorporate the voices of students and staff using multiple methods to seek feedback for refining the quality, feasibility, and contextual fit of the ISLA intervention in middle schools. A total of 53 school staff provided feedback on the ISLA intervention. Further, Design Team members (n = 26) participated in semi-structured interview meetings to inform changes to ISLA. Lastly, student participants (n =
23) engaged in focus groups that were transcribed and coded via an independent co-coding strategy. The findings provide support for preventative school-based interventions that use alternatives to exclusionary discipline, as well as strategies for improving the ISLA intervention.Grant R305A180006, Institute of Education Sciences, U.S. Department of Educatio
Examining the Social Validity of a Universal Intervention for Reducing Exclusionary Discipline through Stakeholder Voice
45 pagesExclusionary disciplinary practices are utilized in schools despite limited benefits and associated negative student outcomes. Alternative strategies, such as Positive Behavioral Interventions and Supports, reduce exclusionary discipline practices, though research is limited
in secondary settings. This study examines how student and school staff input was utilized throughout the iterative refinement of the Inclusive Skill-building Learning Approach (ISLA), an intervention to reduce exclusionary discipline practices in middle school through instructional and restorative practices. Intentional stakeholder involvement was hypothesized to impact acceptability and fidelity of implementation, critical for achieving intervention outcomes. Data across a two-year mixed methods approach indicate that engaging stakeholders throughout implementation enhanced fidelity. Quantitative findings demonstrate better understanding of stakeholder experiences. Implications for practice, limitations, and suggestions for future research are discussed.Grant R305A180006, Institute of Education Sciences, U.S. Department of Educatio
Identification of common genetic risk variants for autism spectrum disorder
Autism spectrum disorder (ASD) is a highly heritable and heterogeneous group of neurodevelopmental phenotypes diagnosed in more than 1% of children. Common genetic variants contribute substantially to ASD susceptibility, but to date no individual variants have been robustly associated with ASD. With a marked sample-size increase from a unique Danish population resource, we report a genome-wide association meta-analysis of 18,381 individuals with ASD and 27,969 controls that identified five genome-wide-significant loci. Leveraging GWAS results from three phenotypes with significantly overlapping genetic architectures (schizophrenia, major depression, and educational attainment), we identified seven additional loci shared with other traits at equally strict significance levels. Dissecting the polygenic architecture, we found both quantitative and qualitative polygenic heterogeneity across ASD subtypes. These results highlight biological insights, particularly relating to neuronal function and corticogenesis, and establish that GWAS performed at scale will be much more productive in the near term in ASD
Genome-wide meta-analysis of 241,258 adults accounting for smoking behaviour identifies novel loci for obesity traits
Few genome-wide association studies (GWAS) account for environmental exposures, like smoking, potentially impacting the overall trait variance when investigating the genetic contribution to obesity-related traits. Here, we use GWAS data from 51,080 current smokers and 190,178 nonsmokers (87% European descent) to identify loci influencing BMI and central adiposity, measured as waist circumference and waist-to-hip ratio both adjusted for BMI. We identify 23 novel genetic loci, and 9 loci with convincing evidence of gene-smoking interaction (GxSMK) on obesity-related traits. We show consistent direction of effect for all identified loci and significance for 18 novel and for 5 interaction loci in an independent study sample. These loci highlight novel biological functions, including response to oxidative stress, addictive behaviour, and regulatory functions emphasizing the importance of accounting for environment in genetic analyses. Our results suggest that tobacco smoking may alter the genetic susceptibility to overall adiposity and body fat distribution.Peer reviewe
Genetic variants associated with subjective well-being, depressive symptoms, and neuroticism identified through genome-wide analyses
Very few genetic variants have been associated with depression and neuroticism, likely because of limitations on sample size in previous studies. Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotypes: subjective well-being (n = 298,420), depressive symptoms (n = 161,460), and neuroticism (n = 170,911). We identify 3 variants associated with subjective well-being, 2 variants associated with depressive symptoms, and 11 variants associated with neuroticism, including 2 inversion polymorphisms. The two loci associated with depressive symptoms replicate in an independent depression sample. Joint analyses that exploit the high genetic correlations between the phenotypes (|ρ^| ≈ 0.8) strengthen the overall credibility of the findings and allow us to identify additional variants. Across our phenotypes, loci regulating expression in central nervous system and adrenal or pancreas tissues are strongly enriched for association.</p
Dissecting the Shared Genetic Architecture of Suicide Attempt, Psychiatric Disorders, and Known Risk Factors
Background Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. Methods We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors. Results Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged. Conclusions Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders.Peer reviewe
Genomic Relationships, Novel Loci, and Pleiotropic Mechanisms across Eight Psychiatric Disorders
Genetic influences on psychiatric disorders transcend diagnostic boundaries, suggesting substantial pleiotropy of contributing loci. However, the nature and mechanisms of these pleiotropic effects remain unclear. We performed analyses of 232,964 cases and 494,162 controls from genome-wide studies of anorexia nervosa, attention-deficit/hyper-activity disorder, autism spectrum disorder, bipolar disorder, major depression, obsessive-compulsive disorder, schizophrenia, and Tourette syndrome. Genetic correlation analyses revealed a meaningful structure within the eight disorders, identifying three groups of inter-related disorders. Meta-analysis across these eight disorders detected 109 loci associated with at least two psychiatric disorders, including 23 loci with pleiotropic effects on four or more disorders and 11 loci with antagonistic effects on multiple disorders. The pleiotropic loci are located within genes that show heightened expression in the brain throughout the lifespan, beginning prenatally in the second trimester, and play prominent roles in neurodevelopmental processes. These findings have important implications for psychiatric nosology, drug development, and risk prediction.Peer reviewe
Moving away from disproportionate exclusionary discipline : developing and utilizing a continuum of preventative and instructional supports
33 pagesAmple scientific research has documented that exclusionary discipline practices are both ineffective for reducing unwanted behaviors and harmful to the long-term social and academic outcomes of students. Further, exclusionary discipline practices are especially harmful given their disproportionate use with students of color, students with disabilities, students living in poverty, and students who are struggling academically. To address these issues, the authors describe a process that uses instructional strategies as alternatives to exclusion. These instructional strategies hold promise for reducing the use of disproportionate discipline, improving student behavior and social skills, and strengthening student–teacher relationships.The research reported here was supported by the Institute of Education Sciences, U.S. Department of Education, through Grant R305A180006 to University of Oregon
Achievement gaps for students with disabilities: Stable, widening, or narrowing on a state-wide reading comprehension test?
Reading comprehension growth trajectories from 3rd to 7th grade were estimated for 99,919 students on a state reading comprehension assessment. We examined whether differences between students in general education (GE) and groups of students identified as exceptional learners were best characterized as stable, widening, or narrowing. The groups included students with disabilities (SWD) from 8 exceptionality groups and 2 groups of academically gifted students (AG). Initial reading comprehension achievement differed for all exceptionalities. Controlling for sociodemographic variables, small, but statistically significant differences in growth rate were observed, with SWD groups growing more rapidly and AG groups growing more slowly than GE students. Given that differences in growth for SWD were small relative to the magnitude of the initial achievement gaps, the observed pattern of growth was one of stable differences. There was evidence of some narrowing of the achievement gap for students identified with learning disabilities in reading. The findings were interpreted within the simple view of reading where increases in word recognition skills for SWD in the grade range examined may have accounted for their more rapid growth in reading comprehension relative to GE students. The findings suggest that similar expectations for rate of reading growth for GE students and SWD might be incorporated into growth-based accountability models, but they also suggest that reading comprehension growth sufficient to have an impact on SWD achievement gaps does not routinely occur in typical educational practice
