Background: Black and Hispanic adults with diabetes are more likely to experience diabetes complications and die from diabetes compared to non-Hispanic whites. This disparity may be due to medication adherence being negatively affected by social determinants of health (SDOH) and negative beliefs about diabetes and diabetes medicines. Pharmacist delivered medication therapy management (MTM) improves clinical outcomes.

Introduction: The Clinical Dementia Rating (CDR) Scale is a gold standard for staging impairment in Alzheimer's disease and other dementias (ADRD). The Quick Dementia Rating System (QDRS) offers similar results in 3 to 5 minutes without a trained clinician. This study aimed to (1) investigate concordance between comparably derived QDRS and CDR global scores, (2) examine item-level QDRS/CDR agreement, and (3) compare sample characteristics and cognitive performance across QDRS/CDR global concordant/discordant groups.

Introduction: Prior research suggests that the e-Cigarette Wisconsin Inventory of Smoking Dependence Motives (e-WISDM) distinguishes primary (e-PDM) and secondary dependence (e-SDM), however, there is little research on these e-WISDM dimensions and prior research comprised dual users (using cigarettes and e-cigarettes) and those using older generations of e-cigarettes.

Methods: Those exclusively using contemporary e-cigarettes (N = 164) completed the e-WISDM and a laboratory self-administration session and rated pre-use expectancies and post-use experiences.

Results: Only a 1-factor model limited to the primary scales (Automaticity, Tolerance, Craving, Loss of Control) achieved good model fit.

Importance: A single round of standard tobacco quitline treatment may not be sufficient to sustain abstinence, particularly among people experiencing socioeconomic disadvantage. Adaptive retreatment may help more individuals with socioeconomic disadvantage achieve abstinence and reduce disparities in smoking cessation outcomes.

Objective: To evaluate 4 evidence-based strategies for adults with limited education, no insurance, or Medicaid eligibility who continued smoking after quitline treatment.

Article Synopsis
  • The study looked at how meditation apps, like the Healthy Minds Program, help people feel better, especially those who are feeling really stressed or sad.
  • Researchers found that while people felt less negative emotions during meditation, their good feelings didn’t really change much over time.
  • When people felt happier during meditation, it was linked to them feeling less stressed later on, showing that how we feel while meditating can really matter for our mental health.

Article Synopsis
  • - The study explores the connection between parent mental health (specifically fathers) and the emotional well-being of their autistic children, revealing that both issues are closely linked.
  • - Findings indicate that fathers' mental health, particularly their depression and critical comments, significantly affect both their children's mental health and the quality of their interactions, such as positive remarks.
  • - The research suggests that improving the quality of parent-child relationships can help mitigate mental health issues for both fathers and their autistic children, although similar effects were not observed for mothers.

This study aimed to investigate integration of alternating speech, a stimulus which classically produces a V-shaped speech intelligibility function with minimum at 2-6 Hz in typical-hearing (TH) listeners. We further studied how degraded speech impacts intelligibility across alternating rates (2, 4, 8, and 32 Hz) using vocoded speech, either in the right ear or bilaterally, to simulate single-sided deafness with a cochlear implant (SSD-CI) and bilateral CIs (BiCI), respectively. To assess potential cortical signatures of across-ear integration, we recorded activity in the bilateral auditory cortices (AC) and dorsolateral prefrontal cortices (DLPFC) during the task using functional near-infrared spectroscopy (fNIRS).

We provide an alternative psychometric perspective on the empirical statistical dependencies observed between response accuracy residuals (RARs) and response time residuals (RTRs) in the context of the van der Linden model. This perspective emphasizes the RAR (or parts of the RAR) as being exogenous and having a directional influence on response time. Our simple and theoretically justifiable perspective adds to previous joint response time/accuracy models and comports with recent generalizations of the D-diffusion IRT model incorporating person-by-item interactions, and thus similarly reproduces many of the recently highlighted empirical findings concerning the associations between RARs and RTRs.

Domain-general prediction differences have been posited as underlying many aspects of the cognitive-behavioral profile in autism. An interesting potential implication of such differences is hyperplasticity of learning-the idea that autistic individuals may privilege more recent input over the accumulation of prior learning. Because real world language input is highly variable, hyperplasticity could have serious ramifications for language learning.

Bidirectional associations between changes in symptoms and alliance are established for in-person psychotherapy. Alliance may play an important role in promoting engagement and effectiveness within unguided mobile health (mHealth) interventions. Using models disaggregating alliance and psychological distress into within- and between-person components (random intercept cross-lagged panel model), we report bidirectional associations between alliance and distress over the course of a 4-week smartphone-based meditation intervention (=302, 80.

Article Synopsis
  • The study aimed to evaluate the effectiveness of three different interventions for helping patients maintain smoking abstinence after relapse.
  • A total of 1,154 patients participated, with 582 relapsing and being randomized into various treatment groups that included counseling, nicotine mini-lozenges, and quitline referrals.
  • Results showed that neither additional skill training nor supportive counseling improved long-term abstinence rates, and the "preparation" intervention was not significantly more effective than simply advising patients to contact a quitline.

Introduction: Within two-parent households, the parent-couple subsystem (marital or romantic partner relationship) is posited to shape the mental health of both parents and children. Autistic children and their parents have an elevated-risk for mental health problems. The present study longitudinally examined the mediating role of the quality of the parent-couple relationship in time-ordered pathways between changes in the mental health problems of autistic children and in parent depression symptoms at a within-family level.

Background: Pre-purchase examinations (PPEs) are performed for prospective purchasers of horses to identify prejudicial findings that could make animals unsuitable for an intended use. Although this examination process is often standardised, PPEs remain, in large parts, a subjective procedure. In the United Kingdom, PPEs generally consist of either a two stage (two stage vetting [2SV], i.

Autistic individuals and their families are at risk for poor outcomes in employment and mental health and may be vulnerable to long-term effects of broader societal conditions. The aim of the current longitudinal study was to understand the impact of the Great Recession of 2007-2009 on autistic individuals and their mothers (N = 392). Hierarchical linear modeling (HLM) results indicated that problem behavior of autistic adults increased in the years following the recession.

Limited evidence is available relating gait changes to diagnostic anaesthesia. We investigated associations between specific movement patterns and diagnostic anaesthesia of different anatomical structures in a retrospective analysis. Referral-level lameness cases were included with the following criteria: presence of diagnostic anaesthesia of a forelimb and/or hind limb; subjective efficacy classified as "negative", "partially positive", or "positive"; quantitative gait data available from inertial measurement units.

Item response theory (IRT) analyses are often used to evaluate measurement error in educational and psychological test instruments. In such contexts, the latent traits/proficiencies are typically assumed normally distributed and a cumulative normal/logistic measurement link function is applied. Such choices are consistent with constructs that are viewed as bipolar in nature and play a critical role in defining the latent proficiency metric against which the measurement error in the test is evaluated.

Test speededness refers to a situation in which examinee performance is inadvertently affected by the time limit of the test. Because speededness has the potential to severely bias both person and item parameter estimates, it is crucial that speeded examinees are detected. In this article, we develop a change-point analysis (CPA) procedure for detecting test speededness.

Methodological studies of response time on noncognitive assessments have separately demonstrated the relevance of content trait level and response styles as predictive factors. In this paper we examine the simultaneous relevance of both factors as well as the potential for omitted predictor bias when ignoring either factor. Using response time data from several different noncognitive assessments, we demonstrate how a multilevel regression model that attends simultaneously to content and response style factors leads to consistent findings that support the simultaneous relevance of both factors.

Previous studies have demonstrated evidence of latent skill continuity even in tests intentionally designed for measurement of binary skills. In addition, the assumption of binary skills when continuity is present has been shown to potentially create a lack of invariance in item and latent ability parameters that may undermine applications. In this article, we examine measurement of growth as one such application, and consider multidimensional item response theory (MIRT) as a competing alternative.

Test items for which the item score reflects a sequential or IRTree modeling outcome are considered. For such items, we argue that item-specific factors, although not empirically measurable, will often be present across stages of the same item. In this paper, we present a conceptual model that incorporates such factors.

We respond to the commentaries on Lyu, Bolt and Westby's "Exploring the effects of item specific factors in sequential and IRTree models." The commentaries raise important points that allow us to clarify our theoretical expectation for item specific factors in many educational and psychological test items. At the same time, we agree with the commentaries in acknowledging challenges associated with providing empirical evidence for their presence and reflect on strategies that might support their estimation.

Unlabelled: A problem to implement conservation strategies is that in many cases recognized taxa are in fact complexes of several cryptic species. Failure to properly delineate species may lead to misplaced priorities or to inadequate conservation measures. One such species complex is the yellow-spotted ringlet , which comprises several phenotypically distinct lineages, whose degree of genomic isolation has so far not been assessed.
