RESUMEN

Many decision-making tasks are characterized by a combination of diagnostic and non-diagnostic information, yet models of responding and confidence almost exclusively focus on the contribution of diagnostic information (e.g., evidence associated with stimulus discriminability), largely ignoring the contribution of non-diagnostic information. An exception is Baranski and Petrusic's Journal of Experimental Psychology: Human Perception and Performance, 24(3), 929-945, (1998) doubt-scaling model, which predicts a negative relationship between non-diagnostic information and confidence, and between non-diagnostic information and accuracy. In two perceptual-choice tasks, we tested the effects of manipulating non-diagnostic information on confidence, accuracy and response time (RT). In Experiment 1, participants viewed a dynamic grid consisting of flashing blue, orange and white pixels and indicated whether the stimulus was predominantly blue or orange (using a response scale ranging from low-confidence blue to high-confidence orange), with the white pixels constituting non-diagnostic information. Increasing non-diagnostic information reduced both confidence and accuracy, generally slowed RTs, and led to an increase in the speed of errors. Experiment 2 replicated these results for a decision-only task, providing further support for the doubt-scaling model of confidence.

RESUMEN

The impact of COVID-19 has led to a substantial economic and psychosocial burden on the Latinx population. However, few studies have evaluated how COVID-19 symptoms may exacerbate suicide risk indicators among Latinx persons, or the particular social determinants of health facilitating such detrimental effects. The present study examined the association between self-reported COVID-19 symptoms and suicide likelihood (i.e., self-reported perceived likelihood that one will attempt suicide in the future) among Latinx individuals within a timeframe involving high COVID-19 contagion before the onset of vaccine dissemination. Further, the possible moderating role of acculturative stress in the association between COVID-19 symptoms and suicide likelihood was examined. The sample included 200 Latinx participants (67.5% male, Mage = 34.67 years, SD = 9.15) who completed self-report measures on COVID-19 symptoms, suicide likelihood, acculturative stress, depressive symptoms, trauma symptoms, somatic symptoms, and general COVID-19 emotional impact. Findings indicated that self-reported COVID-19 symptoms were positively associated with suicide likelihood. Further, the association between COVID-19 symptoms and suicide likelihood was moderated by acculturative stress, such that the association was only statistically significant at mean or higher levels of acculturative stress but was not significant among participants with lower acculturative stress. The moderation effect was statistically significant after controlling for sociodemographic factors, depressive symptoms, trauma symptoms, somatic symptoms, and the general emotional impact of the COVID-19 pandemic. The current findings indicate that, among Latinx individuals, acculturative stress is a key social determinant of health for marked psychological distress in the context of the COVID-19 pandemic.

RESUMEN

Importance: Algorithms are commonly incorporated into health care decision tools used by health systems and payers and thus affect quality of care, access, and health outcomes. Some algorithms include a patient's race or ethnicity among their inputs and can lead clinicians and decision-makers to make choices that vary by race and potentially affect inequities. Objective: To inform an evidence review on the use of race- and ethnicity-based algorithms in health care by gathering public and stakeholder perspectives about the repercussions of and efforts to address algorithm-related bias. Design, Setting, and Participants: Qualitative methods were used to analyze responses. Responses were initially open coded and then consolidated to create a codebook, with themes and subthemes identified and finalized by consensus. This qualitative study was conducted from May 4, 2021, through December 7, 2022. Forty-two organization representatives (eg, clinical professional societies, universities, government agencies, payers, and health technology organizations) and individuals responded to the request for information. Main Outcomes and Measures: Identification of algorithms with the potential for race- and ethnicity-based biases and qualitative themes. Results: Forty-two respondents identified 18 algorithms currently in use with the potential for bias, including, for example, the Simple Calculated Osteoporosis Risk Estimation risk prediction tool and the risk calculator for vaginal birth after cesarean section. The 7 qualitative themes, with 31 subthemes, included the following: (1) algorithms are in widespread use and have significant repercussions, (2) bias can result from algorithms whether or not they explicitly include race, (3) clinicians and patients are often unaware of the use of algorithms and potential for bias, (4) race is a social construct used as a proxy for clinical variables, (5) there is a lack of standardization in how race and social determinants of health are collected and defined, (6) bias can be introduced at all stages of algorithm development, and (7) algorithms should be discussed as part of shared decision-making between the patient and clinician. Conclusions and Relevance: This qualitative study found that participants perceived widespread and increasing use of algorithms in health care and lack of oversight, potentially exacerbating racial and ethnic inequities. Increasing awareness for clinicians and patients and standardized, transparent approaches for algorithm development and implementation may be needed to address racial and ethnic biases related to algorithms.

RESUMEN

OBJECTIVE: The present study sought to better understand the characteristics of those who own firearms in the Black community; and to understand how Black firearm owners differ from nonfirearm owning Black individuals on a variety of variables related to safety, threat concerns, and suicide risk. METHODS: Two samples were utilized in this study. The first was a subsample of those who identified as Black from a nationally representative sample (N = 502) seeking to understand firearm ownership within the United States. The second used a subsample of those who identified as Black (N = 1086) from a representative sample from New Jersey, Minnesota, and Mississippi. Variables related to safety and threat concerns were included in the second sample. RESULTS: In both samples, multiple demographic variables, such as being a woman and having higher education, predicted firearm ownership. In the second sample, experiences of everyday discrimination and crime experiences were associated with firearm ownership. Additionally, Black firearm owners reported significantly more suicidal ideation than Black nonfirearm owners. CONCLUSION: The findings demonstrate the unique characteristics and experiences of Black firearm owners and show that firearm ownership is associated with increased suicide risk factors for Black adults. Findings should be used to advocate for the creation of more culturally relevant suicide prevention and firearm means safety strategies.

RESUMEN

Objectives: This study examined the frequency and impact of traumatic events on the mental health of older African American and Black Caribbean adults. Methods: The current study used data from the National Survey of American Life of 1,135 African American and 426 Black Caribbean adults aged 50 and older. Analysis examined the impact of traumatic events on both positive (i.e., happiness and life satisfaction) and negative (i.e., depressive symptoms, psychological distress, and 12-month anti-depressant use) domains of mental health. Results: Findings indicate that approximately 80% of older African Americans and Black Caribbeans reported experiencing a traumatic event at some point in their lifetime. Among African Americans assaultive violence was associated with more depressive symptoms, lower levels of life satisfaction, and lower levels of happiness. This was not the case among Black Caribbeans. Conclusions: These findings provide preliminary insight in mental health outcomes for older African American and Black Caribbean adults.

RESUMEN

Background: Mexican Americans represent the largest subpopulation among Latinx persons and experience numerous health inequalities for psychological symptoms and behavioral health problems. First generation Mexican Americans are particularly vulnerable to such disparities and past work suggests that the experience of acculturative stress may play a vital role in terms of mental and physical health problems among this population. The current study sought to bridge past work on acculturative stress among first-generation Mexican Americans by exploring the role of anxiety sensitivity (AS; fear of the negative consequences of internal sensations) as a potential mediational factor in terms of psychological and behavioral health problems among this group. Methods: The current study consisted of 369 first generation Mexican American persons (86.2% female, 40.1 years of age (SD = 11.1) years in the U.S. attending a Federally Qualified Healthcare Center located in an urban southwestern community. We explored whether AS served as a mediator between acculturative stress and some of the most common and disabling clinical problems among this group, including social anxiety, anxious arousal, general depression, insomnia and pain intensity and disability. Result: Consistent with prediction, there was a statistically significant indirect effect of acculturative stress via AS across all criterion variables apart from pain intensity (depression [ab = - 0.17, SE = 0.05, 95% CI [0.08, 0.26]], insomnia [ab = 0.07, SE = 0.02, 95% CI [0.03, 0.10]], social anxiety [ab 0.05, SE = 0.02, 95% CI [0.02, 0.08]], anxious arousal [ab = 0.08, SE = 0.03, 95% CI [0.03, 0.12]], pain disability [ab = 0.05, SE = 0.02, 95% CI [0.02, 0.09]]). Comparative models were run to evaluate the specificity of hypothesized statistically significant models. For all models except anxious arousal and general depression, the alternative model was rejected, adding support to the hypothesized pathway. Conclusion: Overall, this work provides initial support for the role of AS in terms of the relation between acculturative stress and numerous psychological and behavioral health problems among Mexican American adults in a clinical setting.

RESUMEN

Introduction: The rapid development of coronavirus disease 2019 (COVID-19) into a pandemic required people to quickly acquire, evaluate, and apply novel complex health-related information about the virus and transmission risks. This study examined the potentially unique and synergistic roles of individual differences in neurocognition and health literacy in the early uptake and use of COVID-19 public health information.Method: Data were collected between April 23 and 21 May 2020, a period during which 42 out of 50 states were under a stay-at-home order. Participants were 217 healthy adults who completed a telephone-based battery that included standard tests of neurocognition, health literacy, verbal IQ, personality, and anxiety. Participants also completed measures of COVID-19 information-seeking skills, knowledge, prevention intentions, and prevention behaviors.Results: A series of hierarchical multiple regressions with data-driven covariates showed that neurocognition (viz, episodic verbal memory and executive functions) was independently related to COVID-19 knowledge (e.g. symptoms, risks) at a medium effect size, but not to information-seeking skills, prevention intentions, or prevention behaviors. Health literacy was independently related to all measured aspects of COVID-19 health information and did not interact with neurocognition in any COVID-19 health domain.Conclusions: Individual differences in neurocognition and health literacy played independent and meaningful roles in the initial acquisition of knowledge related to COVID-19, which is a novel human health condition. Future studies might examine whether neurocognitive supports (e.g. spaced retrieval practice, elaboration) can improve COVID-19-related knowledge and health behaviors in vulnerable populations.

RESUMEN

BACKGROUND: Anxiety sensitivity (AS), defined as the fear of anxiety-related sensations, is associated with increased risk for suicide and related behavior. However, investigations of AS have centered on primarily non-Hispanic White men and women and with limited attention to clinically relevant underlying factors. METHODS: The purpose of this preliminary study was to examine the indirect effect of AS on suicide ideation and elevated suicide risk through mindfulness in a sample of 307 Black adults (79.2% female; Mage = 22.4, SD = 5.6). Participants completed an online questionnaire battery that included measures of AS, mindfulness, suicide ideation, and elevated suicide risk. RESULTS: After controlling for age and gender, results indicated that AS was directly and indirectly associated with suicide ideation and elevated suicide risk via lower levels of mindfulness. LIMITATIONS: Limitations include using a cross-sectional methodological design and exclusive reliance on self-report measures. CONCLUSIONS: These findings provide preliminary insight into novel risk and protective factors that influence suicide ideation and elevated suicide risk among Black Americans.

RESUMEN

OBJECTIVES: Perceived racial discrimination is associated with depressive symptoms for African American adults; however, insight to protective factors for racism and depression in African Americans is limited. While current research suggests that dispositional forgiveness is an important factor in how people perceive and cope with interpersonal transgressions, few studies have examined its role in the context of racial discrimination. The purpose of this study was to examine the moderating effect of forgiveness (beyond broader internalized religiosity) on the association between perceived racial discrimination and depressive symptoms in African American adults. METHOD: Sample included 101 African American adults (60.2% female; Mage = 21.90 years, SD = 4.93 years) who endorsed experiences of racial discrimination. Participants completed a questionnaire battery consisting of self-report measures of perceived experiences of racial discrimination, depression, dispositional forgiveness, and intrinsic religiosity. RESULTS: Regression analyses showed dispositional forgiveness moderated the association between perceived racial discrimination and symptoms of depression above and beyond intrinsic religiosity (ß = -.05, 95% CI [-.10, -.05], p < .05), such that the racial discrimination-depression association was significant for participants who reported low levels of dispositional forgiveness, but not for individuals who reported higher levels of dispositional forgiveness. CONCLUSIONS: These findings provide insight into the role of dispositional forgiveness in experiences of racial discrimination and suggest that cognitive flexibility serves as an adaptive coping strategy to experiencing discrimination.

RESUMEN

OBJECTIVE: To examine the factor structure and sociodemographic correlates of a battery of clinical neuropsychological tests administered in-home and via telephone. METHOD: Participants included 280 healthy adults who completed a 35-40 min battery consisting of seven auditory-verbal neuropsychological tests (i.e., 10 variables) that included digit span, list learning and memory, prospective memory, verbal fluency, and oral trail making. RESULTS: After removing oral trail making part A, a three-factor model comprised of executive functions, memory and attention demonstrated the best fit to the data. Nevertheless, the shared variance between the nine remaining neuropsychological variables was also adequately explained by a single-factor model and a two-factor model comprised of executive functions and memory. Factor scores were variably associated with education, race/ethnicity, and IQ, but not with sex or age. CONCLUSIONS: Findings provide preliminary support for the feasibility and factor structure and sociodemographic correlates of a brief telephone-based screening neuropsychological battery comprised mostly of commonly administered clinical measures. Future studies are needed to determine the test-retest reliability, sensitivity, and ecological relevance of this battery, as well as equivalency to in-person assessment.

RESUMEN

OBJECTIVE: Developing the capability to die by suicide, and overcoming one's natural instinct of self-preservation, is thought to occur as a result of habituation to the fear and pain surrounding suicide. However, investigations of suicide capability have yet to examine whether perceived discrimination serves as a painful and provocative event that contributes to capability for suicide. The purpose of the current study was to examine the association of perceived discrimination and suicide capability for Black and White adults. METHOD: The study sample included 173 Black adults (67.6% female; Mage  = 23.18, SD = 5.74) and 272 White adults (60.7% female; Mage  = 22.80, SD = 5.90). Participants completed a questionnaire battery that included measures of perceived discrimination, depression, and suicide ideation. RESULTS: Regression analyses revealed for Black adults (but not White adults), perceived discrimination was associated with an increased capability for suicide after accounting for depressive symptomatology, suicide ideation, non-discriminatory painful and provocative events experienced, age, and gender (ß = .226, t = 3.154, p = .002). CONCLUSIONS: These findings provide preliminary evidence that perceived discrimination may play a role in suicide capability for Black adults and highlight the importance of considering contextual experiences when examining suicidality in underserved groups.

RESUMEN

INTRODUCTION: The current study highlights the voices and perspectives of African American fathers, with specific emphasis on their race-related concerns for their adolescents as well as how these concerns guide their parenting strategies. METHOD: Twenty-four African American fathers participated in 1.5-3 h long focus group interviews. All fathers (M = 42.24 years, SD = 6.93) resided in a mid-sized city in the Southeastern United States. All participants were either biological fathers (n = 20) or non-biological (n = 4) fathers. Fathers were residential (76%) and non-residential (24%), with at least one adolescent child (M = 14.32 years, SD = 5.80; Range: 10-16 years). Fifty-eight percent of fathers (n = 14) had both male and female children, 29% had only female children (n = 7) and 13% had only male children (n = 3). After codebook development and refinement, key themes were explored using a theoretical thematic analysis. RESULTS: In response to race-related and other social risks for African American adolescents, fathers articulated a number of parenting motivations and intentions: 1) fathers' own racial experiences; 2) negative media images of Black youth and families (e.g. media influences, negative stereotypes, and portrayals of Black fathers); 3) preserving families through community support; 4) developing awareness of discrimination and coping strategies; 5) cultivating positive personal and cultural identities; and 6) achievement as necessity. Also, gender emerged as a critical lens for African American fathers' concerns and parenting strategies. CONCLUSION: Overall, our investigation highlights African American fathers' own meaning-making around concerns for their adolescents as well as how they shape parenting processes.

RESUMEN

Background: Serum proteomic biomarkers offer a promising approach for early detection of cancer. In this study, we aimed to identify proteomic profiles that could distinguish colon cancer cases from controls using serial prediagnostic serum samples.Methods: This was a nested case-control study of active duty military members. Cases consisted of 264 patients diagnosed with colon cancer between 2001 and 2009. Controls were matched to cases on age, gender, race, serum sample count, and collection date. We identified peaks that discriminated cases from controls using random forest data analysis with a 2/3 training and 1/3 validation dataset. We then included epidemiologic data to see whether further improvement of model performance was obtainable. Proteins that corresponded to discriminatory peaks were identified.Results: Peaks with m/z values of 3,119.32, 2,886.67, 2,939.23, and 5,078.81 were found to discriminate cases from controls with a sensitivity of 69% and a specificity of 67% in the year before diagnosis. When smoking status was included, sensitivity increased to 76% while histories of other cancer and tonsillectomy raised specificity to 76%. Peaks at 2,886.67 and 3,119.32 m/z were identified as histone acetyltransferases while 2,939.24 m/z was a transporting ATPase subunit.Conclusions: Proteomic profiles in the year before cancer diagnosis have the potential to discriminate colon cancer patients from controls, and the addition of epidemiologic information may increase the sensitivity and specificity of discrimination.Impact: Our findings indicate the potential value of using serum prediagnostic proteomic biomarkers in combination with epidemiologic data for early detection of colon cancer.

RESUMEN

PURPOSE: Using prostatic fluids rich in glycoproteins like prostate-specific antigen and prostatic acid phosphatase (PAP), the goal of this study was to identify the structural types and relative abundance of glycans associated with prostate cancer status for subsequent use in emerging MS-based glycopeptide analysis platforms. EXPERIMENTAL DESIGN: A series of pooled samples of expressed prostatic secretions (EPS) and exosomes reflecting different stages of prostate cancer disease were used for N-linked glycan profiling by three complementary methods, MALDI-TOF profiling, normal-phase HPLC separation, and triple quadropole MS analysis of PAP glycopeptides. RESULTS: Glycan profiling of N-linked glycans from different EPS fluids indicated a global decrease in larger branched tri- and tetra-antennary glycans. Differential exoglycosidase treatments indicated a substantial increase in bisecting N-acetylglucosamines correlated with disease severity. A triple quadrupole MS analysis of the N-linked glycopeptides sites from PAP in aggressive prostate cancer pools was done to cross-reference with the glycan profiling data. CONCLUSION AND CLINICAL RELEVANCE: Changes in glycosylation as detected in EPS fluids reflect the clinical status of prostate cancer. Defining these molecular signatures at the glycopeptide level in individual samples could improve current approaches of diagnosis and prognosis.

RESUMEN

Expressed prostatic secretions (EPS) are proximal fluids of the prostate that are increasingly being utilized as a clinical source for diagnostic and prognostic assays for prostate cancer (PCa). These fluids contain an abundant amount of microvesicles reflecting the secretory function of the prostate gland, and their protein composition remains poorly defined in relation to PCa. Using expressed prostatic secretions in urine (EPS-urine), exosome preparations were characterized by a shotgun proteomics procedure. In pooled EPS-urine exosome samples, ~900 proteins were detected. Many of these have not been previously observed in the soluble proteome of EPS generated by our labs or other related exosome proteomes. We performed systematic comparisons of our data against previously published, prostate-related proteomes, and global annotation analyses to highlight functional processes within the proteome of EPS-urine derived exosomes. The acquired proteomic data have been deposited to the Tranche repository and will lay the foundation for more extensive investigations of PCa derived exosomes in the context of biomarker discovery and cancer biology.
