RESUMO

The Suicide Status Form-IV (SSF-IV) is the measure used in the Collaborative Assessment and Management of Suicidality (CAMS). The SSF-IV Core Assessment measures various domains of suicide risk. Previous studies established a two-factor solution in small, homogeneous samples; no investigations have assessed measurement invariance. The current investigation sought to replicate previous factor analyses and used measurement invariance to identify differences in the Core Assessment by race and gender. Adults (N = 731) were referred for a CAMS consultation after exhibiting risk for suicide. Confirmatory factor analyses indicated good fit for both one- and two-factor solutions while the two-factor solution is potentially redundant. Configural, metric, and scalar invariance held across race and gender. Ordinal logistic regression models indicated that neither race nor gender significantly moderated the relationship between the Core Assessment total score and clinical outcomes. Findings support a measurement invariant, one-factor solution for the SSF-IV Core Assessment.

RESUMO

OBJECTIVES: Perfectionism is a common transdiagnostic problem that may lead to substantial distress and functional impairments. Cognitive behavioural therapy (CBT) is an effective treatment for perfectionism. However, the existing significant barriers to access and utilization of mental health services, including among college students, demand the development of low-intensity accessible interventions. The aim of the present study was to evaluate the effectiveness of a low-intensity CBT-based self-help gamified app developed specifically for perfectionism in a sample of college students. METHODS: Participants completed assessments of perfectionism, related symptoms, emotional burden and functional impairments at pretreatment, posttreatment and at one-month follow-up. RESULTS: Compared with the waitlist condition (n = 35), the app condition (n = 35) demonstrated a significant and greater reduction in perfectionism, obsessive-compulsive symptoms, functional impairments and subjective ratings of emotional burden. CONCLUSIONS: Results suggest that a brief, daily app-based game-like intervention targeting maladaptive perfectionistic beliefs may be a viable, low-cost alternative to traditional CBT treatments for vulnerable populations on college campuses.

RESUMO

INTRODUCTION: The Virtual Hope Box (VHB) is a smartphone application designed to support emotion regulation when one is distressed, in a crisis, or experiencing suicidal ideation (SI). Initial proof of concept studies indicate that individuals are more likely to use the VHB than traditional hope boxes, and find it both easy to setup and helpful. To our knowledge, no studies have harnessed ambulatory assessment methodology to assess VHB use as it relates to incidence of suicidal thinking. METHODS: As such, we recruited N = 50 undergraduates who endorsed SI either the past year or past 2 weeks to complete a 10-day investigation. At baseline, participants were oriented to the VHB and instructed on how to use the application. Over the next 10 days, participants responded to prompts five times per day on their personal smartphones regarding their current experiences of SI and stress as well as VHB usage. RESULTS: Results found that most participants used the VHB at least once, rated its usefulness as high, and rated their perceived likelihood of future use as high. In addition, increases in state SI severity were related to subsequent VHB use. CONCLUSION: The VHB may be a useful tool for managing crises in undergraduates experiencing suicidal thoughts.

RESUMO

OBJECTIVES: Extant literature suggests that dispositional mindfulness may reduce the impact perceived stress has on the severity of suicidal ideation (SI). Only one study has analyzed this question but did so with a cross-sectional design in a sample of undergraduate women. METHODS: This study analyzed the potential moderating role of dispositional mindfulness on the relation between perceived stress and SI cross-sectionally and at one-week follow-up in a sample of US adults (N = 598) with a history of SI. RESULTS: Results indicated that dispositional mindfulness and its facets were inversely related to perceived stress, SI severity at baseline, and SI severity one week later. At baseline, regression results indicated that only the nonreacting component of dispositional mindfulness interacted with perceived stress to concurrently predict SI severity. This relation was not significant when SI severity was measured one week later. LIMITATIONS: Study results are limited by the high attrition rate from baseline to follow-up and the relatively homogeneous sample. CONCLUSION: Study results indicate that dispositional mindfulness, particularly components related to nonreacting, is inversely related to SI severity concurrently but not prospectively. Interventions focused on mindfulness skills, particularly skills around nonreaction to inner experience, may be beneficial for those considering suicide.

RESUMO

Effective communication is a crucial component of patient-centered care and individuals with low health literacy face significant challenges in managing their health, leading to longer hospital stays and worse outcomes. Visual aids, such as medical illustrations and pictograms, can enhance patient understanding and memory retention; however, there is a lack in the medical field of tools for evaluating and improving a physician's ability to draw clinical illustrations for their patient. This article explores an aesthetic scale created in collaboration between Boston University Medical School and the Boston University Fine-Arts department. The scale scores basic design elements that could reasonably be improved in a clinical setting. A pilot study demonstrated interrater reliability between trained artists scoring images of varying concepts and visual quality with a Cronbach's alpha of 0.95. This scale has potential use in medical visual education and clinical evaluation.

RESUMO

OBJECTIVE: The purpose of the present study was to further investigate the clinical utility of individual and composite indicators within the CPT-3 as embedded validity indicators (EVIs) given the discrepant findings of previous investigations. METHODS: A total of 201 adults undergoing psychoeducational evaluation for ADHD and/or Specific Learning Disorder (SLD) were divided into credible (n = 159) and non-credible (n = 42) groups based on five criterion measures. RESULTS: Receiver operating characteristic curves (ROC) revealed that 5/9 individual indicators and 2/4 composite indicators met minimally acceptable classification accuracy of ≥0.70 (AUC = 0.43-0.78). Individual (0.16-0.45) and composite indicators (0.23-0.35) demonstrated low sensitivity when using cutoffs that maintained specificity ≥90%. CONCLUSION: Given the lack of stability across studies, further research is needed before recommending any specific cutoff be used in clinical practice with individuals seeking psychoeducational assessment.

RESUMO

OBJECTIVE: To examine predictors of informant-reported everyday functioning in mild cognitive impairment (MCI) and relations between everyday function and conversion to dementia. METHODS: Informants of participants (n = 2614) with mild cognitive impairment (MCI) were administered the Functional Activities Questionnaire (FAQ). Changes in dimensions of functional ability as determined by an exploratory factor analysis (EFA) were examined over 3 years and participant predictors of change were examined using multilevel modeling (MLM). RESULTS: The FAQ consisted of 3 factors, multistep, finance, and memory/orientation daily tasks. Impairment in memory/orientation tasks was significantly higher than impairment in multistep tasks. Worse functioning was associated with greater depression, worse memory, worse speed/EF, higher years of education and identifying as White. There was variability in some of these associations with different FAQ factors. Impairments in financial and memory/orientation daily tasks predicted follow-up conversion to dementia. CONCLUSIONS: Depression, speed/EF, and memory are consistently associated with domains of everyday functioning. Race, education, and age may be more variability associated with everyday functioning. Specific attention should be paid to subtle declines in the financial and memory/orientation domains as they may uniquely predict future dementia development. Depression may be a modifiable risk factor associated with functional impairment over time.

RESUMO

Background: The integrated motivational-volitional (IMV) model of suicidal behavior posits that defeat leads to suicidal ideation through increased vulnerability for feelings of entrapment. One potentially important vulnerability factor for the development of feelings of defeat is socially prescribed perfectionism. Aims: The current study investigated these relationships in a sample of 313 US adults. Method: Mediation and parallel mediation analyses were conducted to determine the relationships between defeat, entrapment, social prescribed perfectionism, negative social comparison, and rejection sensitivity. Results: Findings indicated that socially prescribed perfectionism was significantly related to defeat through both negative social comparison and rejection sensitivity even when controlling for depression symptoms. Negative social comparison and rejection sensitivity were related to entrapment through feelings of defeat. This relationship was strongest when analyzing externalized (vs. internalized) entrapment. Limitations: The findings were limited by the cross-sectional study design as well as the relatively homogeneous sample. Implications and future directions are discussed.

RESUMO

Interactive maps can serve as powerful environmental decision-support tools. However, designing an interactive map that meets the needs of diverse constituencies is a challenge. In this article, we evaluate and characterize user needs for an interactive map and spatial decision-support tool called Beescape. Beescape is designed to visualize resources and environmental risks to bees and other pollinators (such as availability of nutritional resources from flowering plants and exposure to pesticides) in order to help users make informed decisions about managing bee populations and associated landscapes. We conducted a needs assessment workshop with twenty stakeholders from four user groups including beekeepers, growers, conservationists, and pollinator scientists to elicit their knowledge to guide future Beescape development. The results of the workshop identify current analytical gaps with the existing Beescape prototype, including the need for predictive and historical tools, more actionable data layers, finer-grain spatial data, and better explanations on what data represent and how they were created. Our findings on user's analytical, informational, and interface needs can be utilized to guide the future development of spatial decision support tools like Beescape, and our methodological approach may apply to other environmental informatics tools where it is important to design for multiple constituent user groups.

RESUMO

Anxiety sensitivity is a transdiagnostic risk factor for internalizing psychopathology in children and adults. Several factor analytic studies have examined the factor structure of anxiety sensitivity in children, adolescents, and adults. However, to date, no studies have specifically examined the factor structure of the Anxiety Sensitivity Index-3 in older adults. The purpose of the current study was to compare the fit of a correlated three-factor, higher-order, and bifactor model of the Anxiety Sensitivity Index-3 (ASI-3) in a sample of older adults. Participants were 856 older adults aged 60-94 recruited through Qualtrics Panels. Confirmatory factor analyses demonstrated good model fit for the bifactor model and the higher-order model and adequate fit for the correlated three-factor model. These results suggests that the ASI-3 is a valid tool assessing anxiety sensitivity in older adults. Limitations and future directions are discussed.

RESUMO

BACKGROUND AND OBJECTIVES: The current study examined relationships between psychopathology and individual domains of executive functioning (EF) amongst adults. While previous studies have examined these relationships using diagnostic groups, we compared factor structures of both dimensional psychopathology and EF and used an approach to better isolate EF-specific task variance within each domain. METHODS: This study analyzed the data of 722 individuals between the ages of 18-59 years, who took part in the Nathan Kline Institute (NKI)-Rockland project. Confirmatory factor analyses were used to derive a three-factor model of EF (i.e., inhibition, shifting, and fluency) proposed by Karr et al. (2019) with scores primarily from the Delis-Kaplan Executive Function System (D-KEFS), as well as a three-factor model of psychopathology (i.e., internalizing, externalizing, and thought disorder symptoms) from the Adult Self-Report (ASR) and Peter's et al. Delusions Inventory (PDI). These models were compared using structural equation modeling. RESULTS: Results demonstrated an adequate fit for both model structures and indicated that internalizing and externalizing psychopathology had positive and negative relationships with different factors of EF, while thought disorder traits were not related to EF. LIMITATIONS: This study examines pathological traits within a non-clinical sample that excluded individuals with severe mental illness. Additionally, analyses were limited by the availability of certain variables, and potential shared method variance within factors. CONCLUSIONS: Patterns of associations with EF were unique to all three aspects of dimensional psychopathology. When examined together, different dimensions of psychopathology were related to both better and worse EF performance.

RESUMO

INTRODUCTION: Although there is some evidence that different symptoms of depression have differential effects on cognition in older adults, these relationships remain understudied in older adults with mild cognitive impairment (MCI). METHOD: Older adults (>50 years old) were classified as having MCI by Alzheimer's Disease Research Centers (ADRCs). Exploratory factor analyses and factor mixture modeling were used to determine depression symptom classes. Classes were then compared across different domains of cognition (i.e., memory, attention, language, and executive function) and informant-rated everyday function. RESULTS: Analyses revealed six, distinct symptom classes (i.e., somatic symptoms, severely depressed, anhedonic symptoms, cognitive symptoms, minimally depressed, and low life satisfaction symptoms). Classes significantly varied on all measures of cognition and everyday function. In particular, the anhedonic class often showed the most substantial decline (on par with the severely depressed class), while the low life satisfaction class often showed the least (on par with the minimally depressed class). CONCLUSIONS: To our knowledge, this is the first study to examine the relationship between depression symptom profiles and cognitive and everyday function in those with MCI. Our findings show that depression symptoms greatly differ in their associations with cognitive and everyday function. It may be beneficial for clinicians to specifically note if patients with MCI are reporting anhedonic and somatic symptoms of depression specifically.

RESUMO

INTRODUCTION: Mentor relationships are important in developing and supporting professional self-efficacy among psychology trainees. Additionally, the rapid diversification of the United States calls for the preparation of clinical neuropsychology trainees to work within a multicultural context. The present study aimed to assess neuropsychology trainees' perceptions of multicultural climate and supervision and if these perceptions differ based on trainee demographics. We also sought to identify aversive experiences of trainees, program strengths or weaknesses, and how programs support trainees. METHOD: Participants were 310 neuropsychology trainees (Mean age = 30.27, SD = 5.67) from clinical psychology graduate (n = 136), pre-doctoral internship (n = 38), and post-doctoral (n = 71) programs across the United States and Canada who completed a survey assessing perceptions to multicultural climate and supervision. 64.5% self-identified as women, 60.3% as heterosexual, and 46.1% as non-Hispanic White. 34.5% of trainees reported at least one American Disabilities Act (ADA) recognized disability. RESULTS: Though satisfied with general supervision, trainees reported overall dissatisfaction with multicultural supervision. Satisfaction with multicultural supervision did not differ by demographics. Trainees also reported various aversive experiences with supervisors, clients, and research participants that negatively impacted their training. These experiences were at times due to an aspect of the trainee's multicultural identity, with Black and Hispanic trainees being more likely to report an aversive experience. Trainees reported ways in which they felt unsupported by their programs. CONCLUSIONS: Important areas of growth for programs are discussed. Issues raised by neuropsychology trainees overlap to some degree with the experiences of trainees in other fields. Recommendations of approaches that have been successfully adopted in other fields to improve trainee satisfaction are provided. Early identification of needs that go above and beyond clinical training will allow programs to respond promptly, improve trainee satisfaction, and potentially improve the retention of trainees from diverse backgrounds.

RESUMO

Mitochondrial glutamate-oxaloacetate transaminase 2 (GOT2) is part of the malate-aspartate shuttle, a mechanism by which cells transfer reducing equivalents from the cytosol to the mitochondria. GOT2 is a key component of mutant KRAS (KRAS*)-mediated rewiring of glutamine metabolism in pancreatic ductal adenocarcinoma (PDA). Here, we demonstrate that the loss of GOT2 disturbs redox homeostasis and halts proliferation of PDA cells in vitro. GOT2 knockdown (KD) in PDA cell lines in vitro induced NADH accumulation, decreased Asp and α-ketoglutarate (αKG) production, stalled glycolysis, disrupted the TCA cycle, and impaired proliferation. Oxidizing NADH through chemical or genetic means resolved the redox imbalance induced by GOT2 KD, permitting sustained proliferation. Despite a strong in vitro inhibitory phenotype, loss of GOT2 had no effect on tumor growth in xenograft PDA or autochthonous mouse models. We show that cancer-associated fibroblasts (CAFs), a major component of the pancreatic tumor microenvironment (TME), release the redox active metabolite pyruvate, and culturing GOT2 KD cells in CAF conditioned media (CM) rescued proliferation in vitro. Furthermore, blocking pyruvate import or pyruvate-to-lactate reduction prevented rescue of GOT2 KD in vitro by exogenous pyruvate or CAF CM. However, these interventions failed to sensitize xenografts to GOT2 KD in vivo, demonstrating the remarkable plasticity and differential metabolism deployed by PDA cells in vitro and in vivo. This emphasizes how the environmental context of distinct pre-clinical models impacts both cell-intrinsic metabolic rewiring and metabolic crosstalk with the TME.

RESUMO

To examine how differences in language experience and sociolinguistic context impact cognitive control, 146 Spanish-English bilingual participants were tested on a non-linguistic Stroop arrows task. Dimensions of language experience included a continuum of L2 proficiency, exposure, age of L2 acquisition, and English receptive vocabulary, along with cognitive non-verbal reasoning. Sociolinguistic context varied with more exposure to Spanish for participants in Southern California (SoCal) than in the Midwest. The task involved perceptual stimulus-stimulus conflict within stimulus features (e.g., right-pointing arrow on the left side of a display). Reaction times to trials where arrow location and direction matched (congruent), mismatched (incongruent), or arrow location was centered (neutral) were used to calculate Stroop (incongruent-congruent), facilitation (neutral-congruent), and inhibition (incongruent-neutral) effects. When examining performance on a continuum of bilingual language experience, individual differences in linguistic background (i.e., L2 proficiency and exposure, receptive vocabulary) and cognitive abilities (i.e., non-verbal reasoning abilities) predicted more efficient performance on the Stroop task. Across sociolinguistic contexts, findings revealed better performance via smaller Stroop and facilitation effects in the Midwest than in SoCal, and no group difference on the inhibition effect. We conclude that research on the cognitive consequences of bilingualism must consider a continuum of language experiences and must be situated in broader naturalistic contexts that take into account the sociolinguistic environments of language use.

RESUMO

The present study aimed to examine the relationship between perfectionism, OCD symptom dimensions, harm avoidance, and incompleteness at varying levels (i.e., higher-order/subscale) in college students. College students (n = 548) completed measures of perfectionism, obsessive-compulsive symptoms, harm avoidance and incompleteness. The results revealed that all five higher-order dimensions of perfectionism were related to incompleteness but only three were related to harm avoidance. Parallel mediation revealed an indirect relationship between concern for mistakes and doubts about actions and checking and cleaning behaviors, respectively, through incompleteness. An indirect relationship between concern for mistakes and doubts about actions with ordering, respectively, through both incompleteness and harm avoidance was found. However, incompleteness played a stronger role than harm avoidance in this relationship. These results suggest that incompleteness might be a stronger motivator than harm avoidance for perfectionistic individuals. Therefore, interventions targeting incompleteness should be implemented to potentially circumvent the development or worsening of obsessive-compulsive symptoms.

RESUMO

The current work investigates whether language dominance predicts transfer of skills across cognitive-linguistic levels from the native language (Spanish) to the second language (English) in bilingual preschoolers. Sensitivity to cognates (elephant/elefante in English/Spanish) and metalinguistic awareness (MLA) have both been shown to transfer from the dominant to the nondominant language. Examining these types of transfer together using a continuous measure of language dominance may allow us to better understand the effect of the home language in children learning a majority language in preschool. Forty-six preschool-aged, Spanish-English bilinguals completed English receptive vocabulary and metalinguistic tasks indexing cognate effects and MLA. Language dominance was found to predict crosslinguistic (cognate) facilitation from Spanish to English. In addition, MLA skills also transferred from Spanish to English for children with lower English proficiency, and no transfer of MLA was evident for children with higher English proficiency. Altogether, findings suggest that transfer from a dominant first language to a nondominant second language happens at linguistic and cognitive-linguistic levels in preschoolers, although possibly influenced by second language proficiency. The current study has implications for supporting the home language for holistic cognitive-linguistic development.

RESUMO

In the future, farmers will have increasing opportunities to use collaborative smartphone applications for agricultural management. Geospatial information in combination with agricultural-relevant information is a great source of knowledge for farmers. Including maps in collaborative mobile agriculture applications benefits communication processes related to agricultural-relevant questions. Ensuring a positive user experience with map interfaces depends on their design. To develop design guidelines for map-oriented mobile agricultural applications, this study evaluates 24 different map design variations (varying in their elements and degrees of complexity) and characterizes their user experience with 72 coffee farmers as study participants. Our findings show that the most crucial factors for a positive user experience were restricted interactivity, simple tasks to conduct (selecting single point features), and a simplified base map style, highlighting relevant landmarks. Since our farmers consisted primarily of less-experienced smartphone and map users, our findings may also be helpful for users in general, sharing similar user characteristics. While empirical, in-situ studies pose many challenges, they provide relevant insights into the real use situation and user behavior of mobile map applications. Our findings help establish some basic principles for designing map adaptations, serving as a guideline for creating effective mapping applications, which adapt to the farmers' contextual factors. Based on our study results, we suggest future research for continuing conceptualizing principles of map design adaptation and support this effort through empirical, in-situ studies for relating contextual user factors to the adaptation behavior of map applications.

RESUMO

Large US colleges and universities that re-opened campuses in the fall of 2020 and the spring of 2021 experienced high per capita rates of COVID-19. Returns to campus were controversial because they posed a potential risk to surrounding communities. A large university in Pennsylvania that returned to in-person instruction for Fall 2020 and Spring 2021 semesters reported high incidence of COVID-19 among students. However, the co-located non-student resident population in the county experienced fewer COVID-19 cases per capita than reported in neighboring counties. Activity patterns from mobile devices indicate that the non-student resident population near the university restricted their movements during the pandemic more than residents of neighboring counties. Respiratory virus prevention and management in student and non-student populations requires different, specifically targeted strategies.

RESUMO

OBJECTIVE: Previous research has shown that both criterion grouping approaches and cutoff scores can impact PVT classification accuracy statistics. This study aimed to examine the influence of cutoff scores and criterion grouping approaches on The b Test, a measure designed to identify feigned impairment in visual scanning, processing speed, and letter identification. METHOD: Two hundred ninety-seven adults referred for psychoeducational testing were included with the majority of individuals seeking academic accommodations (n = 215). Cutoff scores of ≥82, ≥90, and ≥120 were utilized along with two different criterion group approaches, 0 PVT failures vs. ≥2 PVT failures and 0 PVT failures versus ≥ 1 PVT failures. RESULTS: Failure rates for The b Test in the overall sample ranged from 12.5% to 16.2%. Subgroup analyses in those referred specifically for ADHD revealed failure rates for The b Test ranging from 10.5% to 14.2%. ROC curves within the full sample and ADHD subsample demonstrated significant AUCs utilizing both criterion group approaches (AUC = .66 - .78). Sensitivity and specificity varied as a function of criterion group approach and cutoff score, with 0 PVT failures vs. ≥ 2 PVT failures resulting in the greatest sensitivity when maximizing specificity at ≥.90 in the full sample and ADHD sample. CONCLUSIONS: The results demonstrate that criterion approaches and cutoff scores impact classification accuracy of The b Test with 0 PVT vs. ≥ 2 PVT failures demonstrating the greatest classification accuracy. Special considerations should be made with regard to clinical decision making in the context of psychoeducational evaluations given that a large portion of individuals seeking accommodations fail only one PVT. Limitations of this study are also discussed.
