Article Synopsis
  • Anxiety disorders are the most common psychiatric issues in the U.S., but current assessment tools lack validity measures, which the study aimed to address by creating a symptom validity index for the Beck Anxiety Inventory (BAI).* -
  • The study involved 244 veterans and categorized them into valid and invalid response groups, identifying a cutoff score of ≥ 29 for the overall sample to distinguish valid responses, although specific clinical subgroups required higher cutoffs.* -
  • The research is significant as it's the first to establish a symptom validity index for the BAI, recommending a total score of ≥ 36 to reduce false positives when evaluating current anxiety symptoms.*

Article Synopsis
  • A study investigated psychological and behavioral factors affecting outcomes after bariatric surgery, with a focus on racial differences among participants who completed an online survey.
  • The sample consisted of 733 individuals (87% women, 63% White, average age 44) and found that White participants reported higher anxiety and emotional eating linked to depression, while Black participants showed greater depressive severity.
  • Results indicated that White individuals experienced more disordered eating behaviors, such as loss of control eating and grazing, while also being less likely to skip meals or eat at night compared to Black individuals; addressing depressive symptoms and eating patterns could improve surgery outcomes.

Telepractice has become increasingly utilized in disability services, particularly with recent and ongoing measures to slow the spread of the novel coronavirus (COVID-19). In this study, 361 speech-language pathologists (SLPs) responded to a national, web-based survey about their views on utilizing telepractice with children aged 3 to 21 who used aided augmentative and alternative communication (AAC), such as picture symbols or speech-generating devices. The views of SLPs varied, and SLPs who received training on AAC telepractice within the last 12 months had more positive views about telepractice than those who did not.

Single-case research is a prevalent and useful method for evaluating the effects of interventions in special education research. A single-case graph "should make available all of the data that permit evaluation of the criteria for visual inspection, at the very least," while not misleading inspectors (Kazdin, 2011, p. 335).

Purpose: The global COVID-19 pandemic brought about widespread use of telepractice to provide services to children with communication disorders, including students who use aided augmentative and alternative communication (AAC) such as speech-generating devices. This descriptive quantitative study utilized network analysis to investigate the nature of speech-language pathologists' (SLPs') professional resource networks during the pandemic, including what aspects of their professional networks were associated with their confidence to use telepractice to serve students who use aided AAC and whether there were differences for school-based compared to nonschool-based SLPs.

Method: Participants were 283 SLPs who responded to an online survey that consisted of closed- and open-ended survey items.

Families and education professionals face unique challenges when working together to support augmentative and alternative communication (AAC) for a child who does not use speech and has only prelinguistic forms of communication. For this study, a family-school team was provided with a specially designed support package comprising training and one-on-one coaching in evidence-based instructional strategies. As part of a larger mixed methods investigation, a single-case experimental design was conducted to explore the effectiveness of the support package on facilitating team members' competence in AAC instruction and communication.

Background: Single-case research (SCR) has been a valuable methodology in special education research. Montrose Wolf (1978), an early pioneer in single-case methodology, coined the term "social validity" to refer to the social importance of the goals selected, the acceptability of procedures employed, and the effectiveness of the outcomes produced in applied investigations. Since 1978, many contributors to SCR have included social validity as a feature of their articles and several authors have examined the prevalence and role of social validity in SCR.

Anthocyanins are being increasingly investigated for their neuroprotective and antineuroinflammatory effects; however, the overall bioavailability of many anthocyanins is relatively low. In contrast, phenolic acids, metabolites of many polyphenols, including anthocyanins, have been shown to accumulate in tissue at higher concentrations than those of parent compounds, suggesting that these metabolites may be the bioactive components of anthocyanin-rich diets. We examined the neuroprotective capacity of two common phenolic acids, 4-hydroxybenzoic acid (HBA) and protocatechuic acid (PCA), in primary cultures of cerebellar granule neurons.

Objective: Heparin-induced thrombocytopenia (HIT) occurs in up to 5% of patients exposed to unfractionated heparin for 5 or more days. Direct thrombin inhibitors (DTIs) are currently the only Food and Drug Administration (FDA)-approved agents for the treatment of HIT. The purpose of this study is to determine whether fondaparinux is an appropriate first-line alternative anticoagulant in patients with suspected or confirmed HIT.

How can perceptual consciousness be indexed in humans? Recent work with ERPs suggests that P3b, a relatively late component, may be a neural correlate of consciousness (NCC). This proposal dovetails with currently prevailing cognitive theory regarding the nature of conscious versus unconscious processes, which holds that the latter are simple and very brief, whereas consciousness is ostensibly required for more durable, complex cognitive processing. Using a P3b oddball paradigm, we instead show that P3b and even later, related slow wave activity occur under rigorously subliminal conditions.

While showing unconscious influences on complex decisions is indeed difficult, relevant awareness in relatively simpler subliminal paradigms is more easily assessed. Utilizing objective detection (vs. more typical identification or classification) tasks to assess awareness overcomes longstanding residual methodological problems, and prior work using such methods (e.

Individuals with significant intellectual disabilities who use augmentative and alternative communication (AAC) often fail to acquire large vocabularies. To maximize the functionality of a small vocabulary, AAC users' initial vocabulary typically consists of words that can be used frequently across contexts and functions (i.e.

Our approach is based on a tri-partite method of integrating psychodynamic hypotheses, cognitive subliminal processes, and psychophysiological alpha power measures. We present ten social phobic subjects with three individually selected groups of words representing unconscious conflict, conscious symptom experience, and Osgood Semantic negative valence words used as a control word group. The unconscious conflict and conscious symptom words, presented subliminally and supraliminally, act as primes preceding the conscious symptom and control words presented as supraliminal targets.

Whether or not affect can be unconscious remains controversial. Research claiming to demonstrate unconscious affect fails to establish clearly unconscious stimulus conditions. The few investigations that have established unconscious conditions fail to rule out conscious affect changes.
