Denominational Loyalty on the Cooperative Programme of the Nigerian Baptist Convention Between (2013-2023)

The Baptist Cooperative Programme is a system in which churches, who cooperate with the Nigeria Baptist Convention (NBC), make contributions in the form of certain percentages of their tithes, offerings, and undesignated income to their associations, state conferences, and the national body. This paper explores the effects of denominational loyalty on the Cooperative Programme of the Nigerian Baptist Convention (NBC) and strategies to deepen this loyalty among church members. Social identity theory suggests that individuals define themselves based on their membership in social groups, leading to the formation of an identity that is partly derived from their group membership. The decline in the commitment of churches within this period of ten years is worrisome. The existing problem lies in the need to strengthen denominational loyalty to the Convention amidst changing societal dynamics and competing religious influences. Using secondary sources of data collection, including scholarly articles, books, and Convention reports, this study analyses the historical context and current practices of the Baptist Cooperative Programme. Preliminary findings suggest that the Cooperative Programme plays a crucial role in fostering a sense of belonging and loyalty among members, contributing to the overall growth and sustainability of the denomination. Also, while there is a strong desire for cooperation among Baptist Churches, challenges such as lack of loyalty, proper communication, and financial constraints hinder the commitment of the members. The study concludes that the Baptist Cooperative commitment has the potential to strengthen denominational loyalty among Baptist churches in Nigeria. Hence, by addressing these challenges and building on the potential successes of the Cooperative Programme, the Nigerian Baptist Convention can further enhance unity and cooperation among its member churches, ultimately strengthening the denomination as a whole.

Knowing Better: Motivated Ignorance and Willful Ignorance

Abstract Motivated ignorance is an incentivized absence of knowledge that arises in circumstances of unequal power relations, a self-protective non-knowing which frees individuals from having to reflect on the privileges they have in virtue of membership in a dominant social group. In philosophical discussions, the term “motivated ignorance” gets used interchangeably with “willful ignorance.” In the first half of this paper, using Charles Mills’ (2007) white ignorance as the defining case, I argue that this is a mistake. A significant swath of cases of motivated ignorance are non-willful, or deep, following Rik Peels (2010). But in all cases, benefits accrued to some in virtue of their social position are gained and maintained at the expense of harms to others. In the second half of this paper, I argue that these harms are what ground attributions of culpability in cases of motivated ignorance and drive the normative requirement that the subject know better, so long as the facts in question are ordinarily and easily knowable (in a sense to be specified). Willfulness is not a necessary condition for culpability, even if it is a sufficient one.

Characterization of CKD illness representation profiles using patient-level factors.

Illness perceptions are the unique perspective individuals have on their illness, based on their context and experiences, and are associated with patient outcomes including coping and adherence. The purpose of this study was to explore characteristics that may be driving membership in illness perceptions cluster groups for adults with chronic kidney disease (CKD). This study was conducted within the multicenter longitudinal Chronic Renal Insufficiency Cohort (CRIC) Study. Cross-sectional data were collected and combined with CRIC data. Illness perceptions were measured using the Revised Illness Perception Questionnaire. Clustering analysis was conducted in R, and bivariate analysis including linear regression was performed in STATA 16. The sample (n = 197) had a mean age of 68, was 52% women, 53% non-White, and mean estimated glomerular filtration rate (eGFR) 56 ml/min/1.73 m2. Three cluster groups were identified, labeled as "Disengaged" (n = 20), "Well-Resourced" (n = 108), and "Distressed" (n = 69). The "Disengaged" group was characterized by low CKD knowledge, many recent hospitalization days, and the lowest perceived CKD burden. The "Well-Resourced" group was characterized by the highest levels of education, CKD knowledge, optimism, and medication adherence. The "Distressed" group was characterized by the highest levels of depression scores, comorbidity burden, CKD burden, CKD symptoms, and lowest optimism. Group membership significantly predicted the number of hospitalization days in adjusted analyses. Illness perceptions groups are associated with number of hospitalization days but are independent of many patient characteristics. Illness perceptions data could be used to tailor care for specific patients at risk for poor health outcomes.

If not me then we: Goal tradeoffs in decision-making for the self, ingroup, and outgroup

Navigating the social world requires individuals to balance multiple goals, including the drives to improve one's own outcomes, aid ingroup members, and help or hurt outgroup members. While self-interest and intergroup bias are both well-established motivational phenomena, less is known about how these goals may interact. Here we examine the nature of goal tradeoffs in intergroup decision-making using a novel task in which participants simultaneously make monetary decisions for themselves, an arbitrary ingroup, and the corresponding outgroup. Across four behavioural studies and one eye-tracking study (total N = 704), we find that goals in intergroup contexts are pursued sequentially rather than concurrently, with non-linear upweighting of group-related goals when self-related goals cannot be pursued. Further, we find evidence for stronger self-ingroup than self-outgroup tradeoffs, which manifest in both altered attention to information and altered use of the attended information in decision-making. The results shed light on the cognitive structuring of interrelated goals in intergroup decision-making, furthering our understanding of when and how both intergroup biases and prosocial behaviour may emerge.

Effect of social participation on the trajectories of activities of daily living disability among community-dwelling older adults: a 7-year community-based cohort

IntroductionStudies examining the effects of social participation on activities of daily living (ADL) disability are still scarce.AimTo assess the reciprocal relationship between ADL disability trajectories and social participation among older Chinese people aged ≥ 60 years.MethodsThis study included 2976 participants aged ≥ 60 years in six waves of a community-based survey from 2015 to 2022. Basic activities of daily living (BADL) and instrumental activities of daily living (IADL) were used to assess the ADL disability in each survey. Social participation was assessed by involvement in four social activities and an extensive social participation score. Group-based trajectory modeling was used to identify potential heterogeneity in longitudinal changes over 7 years and explore associations between baseline predictors of group membership and these trajectories.ResultsTwo BADL disability trajectories were identified: stable (94.8%) and increase (5.2%). Additionally, three IADL disability trajectories were distinguished: stable (73.2%), moderate (20.2%), and increase (6.6%). After controlling for the potential covariates, each point increase in the extensive social participation score correlated with a 17% decrease in the odds of older individuals belonging to the increase BADL trajectory group (OR = 0.83, 95% CI = 0.68–1.00). For IADL, it decreased the odds of being assigned to the moderate trajectory group by 16% (OR = 0.84, 95% CI = 0.75–0.95) and to the increase trajectory group by 23% (OR = 0.77, 95% CI = 0.64–0.93).ConclusionsHigher levels of social participation among older individuals were more likely to be classified as stable trajectories in both BADL and IADL. Increased participation in social activities by community-dwelling elderly adults may promote healthy aging.

Social media group support for antidepressant deprescribing: a mixed-methods survey of patient experiences.

Background Antidepressant use has continually increased in recent decades and although they are an effective treatment for moderate-to-severe depression, when there is no longer a clinical benefit, deprescribing should occur. Currently, routine deprescribing is not part of clinical practice and research shows that there has been an increase in antidepressant users seeking informal support online. This small scoping exercise used a mixed-methods online survey to investigate the motives antidepressant users have for joining social media deprescribing support groups, and what elements of the groups are most valuable to them. Methods Thirty members of two antidepressant deprescribing Facebook groups completed an online survey with quantitative and open-text response questions to determine participant characteristics and motivation for group membership. Quantitative data were analysed using descriptive statistics, and open-text responses were analysed thematically through NVivo. Results Two overarching themes were evident: first, clinician expertise , where participants repeatedly reported a perceived lack of skills around deprescribing by their clinician, not being included in shared decision-making about their treatment, and symptoms of withdrawal during deprescribing going unaddressed. Motivated by the lack of clinical support, peer support developed as the second theme. Here, people sought help online where they received education, knowledge sharing and lived experience guidance for tapering. The Facebook groups also provided validation and peer support, which motivated people to continue engaging with the group. Conclusions Antidepressant users who wish to cease their medication are increasingly subscribing to specialised online support groups due to the lack of information and support from clinicians. This study highlights the ongoing need for such support groups. Improved clinician understanding about the complexities of antidepressant deprescribing is needed to enable them to effectively engage in shared decision-making with their patients.

Determinants of financial constraint: a text-based financial constraint index approach

ABSTRACT The study employs a text-based Phrase Matching Method (PMM) index for the financial constraint to identify the key determinants of financial constraints. The study finds that conventional determinants of financial constraint like size, age, dividend payment, long-term borrowing, credit rating, group membership, current ratio, price-to-book ratio, debt-to-equity ratio, capital expenditure, cash flow, and sales growth play a significant role in determining the financial constraint of Indian manufacturing firms. Apart from the conventional determinants, the study also finds that factors like tangibility, R and D intensity, and corporate governance also play an important role in determining financial constraints.

The role of emotional factors in face processing abilities in autism spectrum conditions

Facial emotion recognition is considered atypical in individuals with autism spectrum conditions (ASC), but emotion recognition abilities vary widely in autistic people, and there are inconsistent findings on the causes of these differences. Research indicates alexithymia may result in facial emotion recognition differences in ASC. Alternatively, mood disorders have been linked to atypical facial emotional expression recognition abilities in neurotypical adults. Investigating both the effects of alexithymia and mood disorders (depression and anxiety) is necessary to establish which of these factors may cause atypical facial emotion recognition in ASC. This study aimed to examine whether alexithymia or mood disorder symptomology is a predictor of atypical facial emotion recognition in individuals with ASC. Ninety-eight non-autistic adults and 80 autistic adults were recruited. Participants completed an online facial processing task to examine emotion and identity recognition abilities, the AQ-28, the TAS-20, and the HADS to measure autism severity, alexithymia symptoms, and depression and anxiety symptoms. Regression-based analyses found that autistic traits and autistic group membership did not predict facial emotion processing abilities after accounting for demographic variables, alexithymia and mood disorders: however, neither alexithymia nor mood disorder symptoms predicted variance in face processing abilities either. Our results concur with previous meta-analyses of facial emotion processing in autism spectrum disorder which report that studies do not always report deficits in face processing in autism: our findings are also not supportive of the model that argues that alexithymia explains facial emotion processing difficulties in autism.

The recent star formation histories of nearby galaxies on resolved scales

Abstract Star formation histories (SFHs) of galaxies are affected by a variety of factors, both external (field vs. cluster/group) and internal (presence of a bar and AGN, morphological type). In this work, we extend our previous study and apply the $\langle SFR_{\rm {5}} \rangle \big / \langle SFR_{\rm {200}} \rangle$ metric to a sample of eleven nearby galaxies with MUSE observations. Based on a combination of Hα and UV photometry, $\langle SFR_{\rm {5}} \rangle \big / \langle SFR_{\rm {200}} \rangle$ is sensitive to star formation timescales of ∼5–200 Myr and therefore measures the present-day rate of change in the star formation rate, dSFR/dt. Within this limited galaxy sample, we do not observe systematic variations between the global value of $\langle SFR_{\rm {5}} \rangle \big / \langle SFR_{\rm {200}} \rangle$ and the presence of an active galactic nucleus, stellar bar, nor with group or cluster membership. Within some of the individual galaxies, we however observe significant differences in $\langle SFR_{\rm {5}} \rangle \big / \langle SFR_{\rm {200}} \rangle$ between the arm and interarm regions. In half of the galaxies, the recent SFH of both arm and interarm regions has been very similar. However, in the galaxies with higher bulge-to-total light ratios and earlier morphological type, the SFR is declining more rapidly in the interarm regions. This decline in SFR is not a result of low molecular gas surface density or a decrease in the star formation efficiency, implying that other factors are responsible for this SFR decrease.

Abstract PO1-09-08: Mammography adherence modifies the relationship between multilevel social deprivation and tumor characteristics in the Carolina Breast Cancer Study

Abstract Objective: To describe associations of individual and community socioeconomic status (SES) with breast cancer tumor and treatment characteristics, and to assess potential modification by mammography receipt. Methods: The Carolina Breast Cancer Study is a population-based cohort of women diagnosed with breast cancer between 2008 and 2013. We restricted this analysis to participants with stage 1-3 cancer (n=2,841). Socio-demographic information was obtained during in-home study interviews, and tumor characteristics were obtained from medical records and pathology reports. Community characteristics were obtained from American Community Survey census-tract level data. SES subgroups were identified using latent class analysis, a method for identifying group membership based on multiple shared characteristics. This was done separately using individual data (e.g. household income) and census-tract level data (e.g. poverty rate). We reported prevalence differences (PDs) and 95% CIs for each outcome. Finally, analyses were repeated with stratification by race (Black/non-Black) and receipt of at least one mammogram every 2 years (yes/no), based on self-reported mammography history. Results: Based on the latent class models, participants were sorted into 4 groups based on their individual/community SES: “high/high”, “high/low”, “low/high”, and “low/low”. Black women made up 81% of the low/low group compared to 26% of the high/high. All high individual-SES participants were combined as one referent group because they had similar clinical characteristics regardless of community status. We found that participants with low/low SES had more aggressive tumor characteristics at diagnosis compared to the referent group, such as stage 3 cancer (PD = 5.7%, 2.4-9.0), grade 3 tumor (PD = 9.9%, 5.3-14.4), and triple negative breast cancer (PD = 5.8%, 2.4-9.1). Low/low participants were also more likely to have an interval of at least 30 days between diagnosis and treatment (PD = 4.6%, 0.2-9.0). However, none of these associations were significant for low/high women. When reported separately by race, Black women with low/low SES had greater frequency of stage 3 cancer (PD = 6.3, 1.9-10.8) and prolonged treatment length (PD = 7.5%, 1.1-13.8) compared to high-SES Black women. Race-stratified SES differences were non-significant for genomic subtype and other tumor characteristics like grade and tumor size. After stratifying by screening status, we found that associations of SES with stage and tumor size were only present among those with < 1 mammogram every 2 years. The low/low PDs were (7.9%, 1.5-14.3) for stage 3 and (7.8%, 2.2-13.3) for tumor size >5 cm. Low/low women also had greater frequency of lump detected cancer (PD = 12.6%, 4.0-21.2). In contrast, these associations were not present among women with biannual mammography. Finally, screening status did not modify PDs for genomic subtype (ER+/HER2-, ER-/HER2+, TNBC). Conclusions: Lower community-level SES is associated with less favorable tumor characteristics at diagnosis, mainly among those with low individual SES. Access to mammography may explain part of the disparity in stage and tumor size, suggesting public health benefit for targeted screening initiatives in disadvantaged communities. Still, screening and SES are only 2 mechanisms that contribute to racial disparities; our future work will explore additional intervention points. Demographic and clinical characteristics of CBCS participants by individual and community socioeconomic status (n=2,841) SES groups were derived from latent class models. P-values were assessed by chi-square tests. Participants with race classified as “other” includes all those not identifying as Black or White, including American Indian/Alaska Native, Asian, or another race not listed on the questionnaire.

Abstract PO2-12-01: Five-year quality of life (QOL) trajectories among young breast cancer (BC) survivors

Abstract Background: Young BC survivors are at risk for impaired QOL in part due to issues that are unique to their life stage. We sought to characterize trajectories of QOL in the 5 years following diagnosis among young BC survivors as well as evaluate patient and clinical characteristics associated with poorer or deteriorating QOL trajectories over time. Methods: Women diagnosed with stage I-III BC at age ≤40 enrolled in the Young Women’s BC Study, a prospective cohort in North America, who completed ≥2 study surveys through 5 years of post-diagnosis follow-up. QOL was evaluated with the Cancer Rehabilitation Evaluation System (CARES) physical, psychosocial, and sexual subscale scores. Demographic, treatment, and clinical characteristics were ascertained through surveys and chart review. Longitudinal trajectories for each CARES subscale were defined using group-based trajectory modeling; associations between patient/clinical characteristics and trajectory group membership were estimated for each subscale using multivariable multinomial logistic regression. Results: Among 900 women, median age at diagnosis was 36 (range: 17-40) 89% were white, 2% Black, and 4% Hispanic. At baseline, 73% were partnered, 61% parous and 49% perceived themselves as financially comfortable. Most had hormone-receptor positive (74%), HER2-negative (70%) BC, and most received chemotherapy (82%); 36% underwent mastectomy with radiation. Physical and psychosocial scores each clustered into 4 trajectories, with >75% of participants clustering in groups reflecting excellent or good QOL that was stable over time and few (6% for physical and 4% for psychosocial) clustering into groups that reflected poorer QOL at baseline that did not improve over time. Sexual health trajectories were more variable, clustering into 5 trajectories, with over half of participants clustered into groups reflecting good (35%) or excellent (20%) QOL that remained relatively stable over time, 22% clustered into a trajectory that was poor at baseline but moderately improved over follow-up, 13% in a group that reflected deteriorating from moderate-to-poor QOL and 11% in a group with poor QOL at baseline that did not improve over time. In multivariable regression analyses (Table), factors associated with clustering in a poorer trajectory (vs. clustering in an excellent trajectory), in multiple QOL domains included baseline financial discomfort (associated with poorer QOL across all 3 domains), mastectomy+radiation (vs. lumpectomy, associated with poorer QOL across all 3 domains); chemotherapy receipt (associated with poorer physical and sexual health trajectories); and baseline BMI >25 (vs. 18.5-24.9, associated with poorer physical and poorer/deteriorating sexual health trajectories). Conclusions: Young BC survivors follow distinct QOL trajectories in survivorship. While most will not experience substantial QOL impairment through the first 5 years following diagnosis, a substantial minority report persistently poor or deteriorating QOL. The association between more extensive local therapy and poorer physical/psychosocial/sexual health trajectories underscores the importance of communicating the potential for negative QOL outcomes when women are making surgical decisions. Additionally, the pervasive impact of financial wellbeing on multiple QOL domains supports the potential value of systematic screening for and addressing of financial distress to prevent or mitigate financial toxicity in survivorship Factors associated with clustering in poorer/deteriorating (vs. excellent) QOL trajectories *Reference trajectory=excellent QOL Citation Format: Tal Sella, Zheng Yue, Kathryn Ruddy, Shari Gelber, Rulla Tamimi, Jeffrey Peppercorn, Lidia Schapira, Virginia Borges, Steven Come, Eric Winer, Ann Partridge, Shoshana Rosenberg.

Social capital of families of children with neurodevelopmental disabilities in South India.

To investigate the social capital of families with children with neurodevelopmental disabilities in South India receiving a community-based early intervention (Enabling Inclusion®) program and to explore determinants and associations between social capital and program duration, socio-demographic factors, family empowerment, and caregiver burden. Using purposive sampling in a cross-sectional study design, 217 families (n = 71 received short Enabling Inclusion [<5 months]; n = 146 received long Enabling Inclusion [>9 months]) were recruited and completed the Short Adapted Social Capital Tool (SASCAT: cognitive, structural), measures of family empowerment, and caregiver strain. Descriptive statistics, regression, and correlations were used for analyses. In 52.1% of participants, low cognitive and structural social capital was observed. Higher odds of low structural social capital were observed for mothers with primary versus secondary education (adjusted odds ratio [OR] = 0.35; 95% confidence interval [CI] 0.13-0.90; p = 0.029); and caregivers of children with cerebral palsy versus autism (OR = 4.66; 95% CI 1.02-21.21; p = 0.046). Significant associations were found between structural social capital, the child's age, and support group membership (χ2 = 6.29; 4.70; degrees of freedom [df] = 2; 1; p = 0.04; p = 0.02 respectively), as well as between cognitive social capital and other disability in the family (χ2 = 4.62, df = 1, p = 0.03). While program duration was not found to mediate social capital, mother's education and child's diagnosis emerged as key influential factors, warranting their consideration in interventions supporting families of children with neurodevelopmental disabilities in low- and-middle-income countries and elsewhere.

Creating new resources: The impact of new group memberships on posttraumatic growth in China

AbstractThe Social Identity Model of Traumatic Identity Change proposes the group membership gain hypothesis, which refers to developing positive new group memberships after trauma that may contribute to posttraumatic adjustment. However, only a few empirical studies conducted in Western societies have provided correlational evidence for the hypothesis. The current research conducted three studies to test the hypothesis in China. Study 1 (N = 315) through survey confirmed the positive association between new group memberships and posttraumatic growth among Chinese adults with traumatic experiences. Study 2 (N = 300) replicated the findings through the hypothetical scenario, discovering that participants expected a hypothetical person who experienced trauma and gained new group membership after this trauma would develop posttraumatic growth. Study 3 (N = 300), in a further refined hypothetical scenario (i.e., replacing the hypothetical vignette and protagonist in Study 2), yielded consistent results, demonstrating the impact of new group memberships on anticipated posttraumatic growth behavioral intention. The current research, for the first time in China, examined the group membership gain hypothesis and emphasized the importance of social group membership management in facilitating posttraumatic growth.

Consensus guidelines for the diagnosis and management of succinic semialdehyde dehydrogenase deficiency

Succinic semialdehyde dehydrogenase deficiency (SSADHD) (OMIM #271980) is a rare autosomal recessive metabolic disorder caused by pathogenic variants of ALDH5A1. Deficiency of SSADH results in accumulation of γ-aminobutyric acid (GABA) and other GABA-related metabolites. The clinical phenotype of SSADHD includes a broad spectrum of non-pathognomonic symptoms such as cognitive disabilities, communication and language deficits, movement disorders, epilepsy, sleep disturbances, attention problems, anxiety, and obsessive-compulsive traits. Current treatment options for SSADHD remain supportive, but there are ongoing attempts to develop targeted genetic therapies. This study aimed to create consensus guidelines for the diagnosis and management of SSADHD. Thirty relevant statements were initially addressed by a systematic literature review, resulting in different evidence levels of strength according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) criteria. The highest level of evidence (level A), based on randomized controlled trials, was unavailable for any of the statements. Based on cohort studies, Level B evidence was available for 12 (40%) of the statements. Thereupon, through a process following the Delphi Method and directed by the Appraisal of Guidelines for Research and Evaluation (AGREE II) criteria, expert opinion was sought, and members of an SSADHD Consensus Group evaluated all the statements. The group consisted of neurologists, epileptologists, neuropsychologists, neurophysiologists, metabolic disease specialists, clinical and biochemical geneticists, and laboratory scientists affiliated with 19 institutions from 11 countries who have clinical experience with SSADHD patients and have studied the disorder. Representatives from parent groups were also included in the Consensus Group. An analysis of the survey's results yielded 25 (83%) strong and 5 (17%) weak agreement strengths. These first-of-their-kind consensus guidelines intend to consolidate and unify the optimal care that can be provided to individuals with SSADHD.

Professionalism in Communication Sciences and Disorders: Consideration of Diversity, Equity, Inclusion, and Access

Purpose: This tutorial aims to provide an in-depth discussion of professionalism in communication sciences and disorders (CSD) with consideration of diversity, equity, inclusion, and access. Students, practitioners, and faculty in CSD are taught and held to expectations of professionalism. However, criteria for professionalism often do not fully consider diversity, equity, inclusion, and access. Method: Relevant literature on professionalism and diversity, equity, and inclusion is reviewed and summarized. Case scenarios are also shared to provide examples of how these aspects are not currently considered in the discipline of CSD. Results: The current definitions of professionalism are vague and oftentimes exclude cultural differences. Because the majority of American Speech-Language-Hearing Association membership and leadership groups are from the mainstream culture, the definitions and attributes of professional norms have been influenced by mainstream culture. Conclusions: Recent publications on professionalism and professional behavior in medicine have discussed the impact of racialized professionalism norms on increasing diversity of medical students and trainees. It is imperative to resonate such issues in the CSD profession, because there is a growing number of students and practitioners from minority groups. This tutorial addresses how the discipline of CSD can reflect cultural responsiveness to the standards for students, practitioners, and faculty. Several solutions are suggested.

Long-term Seizure Diary Tracking Habits in Clinical Studies: Evidence from The Human Epilepsy Project

ObjectiveTo characterize seizure tracking patterns of people with focal epilepsy using electronic seizure diary entries, and to assess for risk factors associated with poor tracking. MethodsWe analyzed electronic seizure diary data from 410 participants with newly diagnosed focal epilepsy in the Human Epilepsy Project 1 (HEP1). Each participant was expected to record data each day during the study, regardless of seizure occurrence. The primary outcome of this post-hoc analysis was whether each participant properly tracked a seizure diary entry each day during their study participation. Using finite mixture modeling, we grouped patient tracking trajectories into data-driven clusters. Once defined, we used multinomial modeling to test for independent risk factors of tracking group membership. ResultsUsing over up to three years of daily seizure diary data per subject, we found four distinct seizure tracking groups: consistent, frequent at study onset, occasional, and rare. Participants in the consistent tracking group tracked a median of 92% (interquartile range, IQR: 82%, 99%) of expected days, compared to 47% (IQR:34%, 60%) in the frequent at study onset group, 37% (IQR: 26%, 49%) in the occasional group, and 9% (IQR: 3%, 15%) in the rare group. In multivariable analysis, consistent trackers had lower rates of seizure days per tracked year during their study participation, compared to other groups. SignificanceFuture efforts need to focus on improving seizure diary tracking adherence to improve quality of outcome data, particularly in those with higher seizure burden. In addition, accounting for missing data when using seizure diary data as a primary outcome is important in research trials. If not properly accounted for, total seizure burden may be underestimated and biased, skewing results of clinical trials.

Combining neuropsychological assessment and structural neuroimaging to identify early Alzheimer's disease in a memory clinic cohort.

The current study examined the contributions of comprehensive neuropsychological assessment and volumetric assessment of selected mesial temporal subregions on structural magnetic resonance imaging (MRI) to identify patients with amnestic mild cognitive impairment (aMCI) and mild probable Alzheimer's disease (AD) dementia in a memory clinic cohort. Comprehensive neuropsychological assessment and automated entorhinal, transentorhinal, and hippocampal volume measurements were conducted in 40 healthy controls, 38 patients with subjective memory symptoms, 16 patients with aMCI, 16 patients with mild probable AD dementia. Multinomial logistic regression was used to compare the neuropsychological and MRI measures. Combining the neuropsychological and MRI measures improved group membership prediction over the MRI measures alone but did not improve group membership prediction over the neuropsychological measures alone. Comprehensive neuropsychological assessment was an important tool to evaluate cognitive impairment. The mesial temporal volumetric MRI measures contributed no diagnostic value over and above the determinations made through neuropsychological assessment.

Multiple group membership and executive function in a socioeconomically diverse sample

Belonging to multiple groups is an important feature of our social lives. However, it is largely unknown if it is related to individual differences in cognitive performance. Given that changing self-identities linked to each group requires cognitive operations on knowledge bases associated with each group, the extent to which people belong to multiple groups may be related to individual differences in cognitive performance. Therefore, the main objective of this study was to test if multiple group membership is related to executive function task performance. A socioeconomically diverse sample of 395 individuals in Indonesia participated in this study. Our results show that multiple group membership was positively related to the 3-back working memory performance. However, we also found that this relationship was significant only among participants with high (not median or low) SES. We also observed that Contact diversity was negatively related to working memory performance among participants with low SES. Our results show that the complexity of our social lives is related to individual differences in executive function performance, although this seems to be constrained by SES.

Investigating low intelligence stereotype threat in adults with developmental dyslexia.

Stereotype threat (ST) is a phenomenon that leads to decreased test performance and occurs when one deals with added pressure of being judged on the basis of stereotyped group membership. The ST effect has been previously investigated in many contexts but not in individuals with dyslexia who are often stereotyped as less intelligent. Prevalent use of intelligence tests in job selection processes and employment gap between people with dyslexia and those without warrants this investigation. Sixty-three participants (30 with dyslexia and 33 without dyslexia; mean age = 33.7; SD = 13.7; 47 F, 13 M, three non-binary) were asked to complete intelligence test typically used in selection processes. All participants were randomly assigned to one of three test instruction conditions: (1) they were told the test was diagnostic of their intelligence (ST triggering instruction); (2) test was a measure of their problem-solving skills (reduced threat); (3) or they were simply asked to take the test (control). Results showed that participants with dyslexia in ST condition performed poorer than those in other conditions and those in the same condition who did not have dyslexia. This study provides preliminary evidence for diminishing effects of ST in individuals with dyslexia.
