Early numeracy skills are vital for kindergarten students because they provide the foundation for acquiring mathematics skills in both kindergarten and subsequent years. Teacher support to intervene with kindergarteners at risk for poor mathematics learning outcomes is a promising approach to addressing this achievement gap. The current study replicates previous work on an established early numeracy intervention, ROOTS.

Background: Individuals living with a partner with an alcohol use disorder (AUD) can experience significant psychological distress and use health care more than those without a partner with an AUD. However, the prevailing treatment system's focus on the partner and personal barriers limit these individuals from getting help for themselves. Preliminary work on a self-directed, web-based coping skills training program, Stop Spinning My Wheels (SSMW), shows promise in broadening available treatments for this population.

Research on the development of executive functions (EFs) and self-regulation (SR) has focused heavily on the early childhood years, when these abilities first emerge. Less is known in comparison about how these abilities develop through adolescence, and how contextual factors, such as parenting, influence their development in later years. Using longitudinal data from the Study of Early Child Care and Youth Development (SECCYD), we used random intercept cross-lagged panel modeling (RI-CLPM) to examine the bidirectional linkages between three parenting behaviors (i.

The purpose of the present study was to examine the diagnostic accuracy of different universal screening approaches for identifying mathematics difficulties in kindergarteners. We used extant data from 2,010 kindergarten students from 23 schools across two states. First, we identified the diagnostic accuracy of two individual screeners: (a) a set of three curriculum-based measures (CBM) and (b) a diagnostic measure, the Number Sense Brief (NSB).

Early and prolonged exposure to poverty disrupts biological processes associated with the body's stress response system, leading to long-term negative health outcomes, including obesity, autoimmune disorders, and cardiovascular disease. Allostatic load (AL), a composite measure of chronic stress on the body, is a robust predictor of subsequent health outcomes. However, developmental research examining the associations of early poverty exposure with AL in adolescence, as well as the underlying mechanisms of influence is limited.

Objective: To evaluate whether social networking site (SNS) and dating app use is associated with disordered eating in young men.

Methods: 42 men (18-35y) who reported ≥4 loss of control (LOC) eating episodes in the prior month completed a 14-day ecological momentary assessment (EMA) protocol. Five times throughout the day, participants responded to prompts regarding their dietary restraint, body dissatisfaction, and LOC eating.

It is well established that parenting influences child behavior at home, but less is known about the associations between parenting and teacher reports of child behavior at school, an environment more distal from the home context. This study investigated the presence of authoritarian, authoritative, permissive, and uninvolved parenting styles (PS) in a community sample of 321 parents with kindergarteners (M = 5.45 years) in the Northwestern United States.

Background: Alcohol use disorder (AUD) is an etiologically and clinically heterogeneous condition. Accumulating evidence suggests that persons with lifetime histories of comorbid AUD and non-alcohol substance use disorder (DRUG) constitute an important subgroup of AUD. This study evaluated the distinctiveness of the comorbid AUD/DRUG behavioral phenotype in a community sample with respect to risk factors, AUD course features, and outcome variables assessed at age 30.

High-quality Tier 1 instruction is frequently conceptualized as the "foundation" for other tiers of intervention within multitiered systems of support (MTSS) models. However, the vast majority of Tier 2 intervention studies do not account for Tier 1 variables when examining intervention effectiveness. The purpose of this study was to examine Tier 1 predictors, or "quality indicators," of differential responsiveness to Tier 2 mathematics intervention.

Background: People who inject drugs (PWID) are at greater risk for severe morbidity and mortality associated with COVID-19 due to comorbid, chronic, medical conditions and structural inequities associated with housing instability and incarceration. As such, they are a population that would greatly benefit from COVID-19 vaccination.

Methods: We surveyed 350 syringe exchange clients between March 2021 and June 2021 to collect information on vaccine uptake among PWID, facilitators and barriers to vaccination, and demographic correlates of vaccine hesitancy.

Objective: Knowledge of factors that predict alcohol use disorder (AUD) recurrence or the subsequent switching to a different substance use disorder (SUD) after initial AUD recovery is especially crucial for preventive efforts that seek to alter life courses dominated by problematic substance use. This study evaluated whether the proportions (or densities) of first-degree relatives with AUD and non-alcohol substance use disorder (NASUD) histories predicted AUD recurrence or a new NASUD onset in a family member (i.e.

Objectives: People who inject drugs (PWID) are especially vulnerable to morbidity and mortality as a result of SARS-CoV-2 infection because of social and physical health vulnerabilities. Routine testing for SARS-CoV-2 is critical to reduce transmission. Contingency management-the provision of tangible rewards to reinforce positive behavior-can promote the use of health services among PWID.

Children with autism may display an externalizing problem behavior, which are associated with increased parenting stress and depression in caregivers. Mindful parenting is defined as having a non-judgmental moment-to-moment awareness during caregiver-child interactions. The extant literature is mixed, with some reporting that associations between child problem behavior and parenting stress and depression vary by level of mindful parenting, while others have not found these relations.

The current study evaluated components of existing theoretical models for loss of control (LOC) eating in young men. The link between body image concerns, including concerns with fat and muscularity, and LOC eating frequency was evaluated in 1109 ethnically/racially diverse men (18-30y). Dietary restraint, compulsive exercise, and emotion dysregulation were evaluated as putative mediators.

Objective: Studies of clinical and high-risk samples have demonstrated associations between parental alcohol use disorders (AUDs) and offspring's internalizing and externalizing behavior problems during adolescence and early adulthood. It remains unclear, however, whether associations between parental AUD histories and offspring behavior problems are evident among very young offspring who were not directly exposed to a parent who experienced an active AUD episode during the child's lifetime. The present study sought to evaluate internalizing and externalizing behavior problems among young children as a function of paternal and maternal AUD histories and associated clinical features.

Transitional foods are under-utilized in the adult population as they may provide an opportunity to optimize eating pleasure and nutrition for individuals on a modified texture diet. Yet, little is known about the behavioral properties of transitional foods and no research to date has explored the dissolution of known transitional foods in adults. This study aimed to understand the extent of dissolution of five transitional snacks items in relationship to time, tongue pressure, and amount of saliva.

Implementation of evidence-based practices (EBPs) is paramount to students' development of mathematics proficiency. This study investigated "practice-based evidence" of interventionists' actual use of explicit mathematics instruction, a well-established EBP. Specifically, this study analyzed direct observation data collected in a federally funded efficacy trial involving a Tier 2 first-grade mathematics intervention to examine whether the quantity and quality of explicit mathematics instruction was associated with the mathematics outcomes of 470 first-grade students with or at risk for mathematics learning disabilities.

The objective of this study was to evaluate the effect of a family-centered preventive intervention, the Family Check-Up (FCU), on improving parenting skills during kindergarten and first grade, when children are challenged to engage in a variety of new behaviors, such as sustained attention and self-regulation of behavior in the classroom. Building on prior research and funded by the Department of Education, we tested the effect of the FCU on parenting skills during the transition to kindergarten. We predicted both direct and moderated effects of the FCU on changes in parenting, including positive parenting, monitoring/family routines, and negative parenting skills.
