Experimentally induced distraction impacts cognitive but not emotional processes in think-aloud cognitive assessment

Gender and ethnicity bias in medicine: a text analysis of 1.8 million critical care records

Gender and ethnicity biases are pervasive across many societal domains including politics, employment, and medicine. Such biases will facilitate inequalities until they are revealed and mitigated at scale. To this end, over 1.8 million caregiver notes (502 million words) from a large US hospital were evaluated with natural language processing techniques in search of gender and ethnicity bias indicators. Consistent with nonlinguistic evidence of bias in medicine, physicians focused more on the emotions of women compared to men and focused more on the scientific and bodily diagnoses of men compared to women. Content patterns were relatively consistent across genders. Physicians also attended to fewer emotions for Black/African and Asian patients compared to White patients, and physicians demonstrated the greatest need to work through diagnoses for Black/African women compared to other patients. Content disparities were clearer across ethnicities, as physicians focused less on the pain of Black/African and Asian patients compared to White patients in their critical care notes. This research provides evidence of gender and ethnicity biases in medicine as communicated by physicians in the field and requires the critical examination of institutions that perpetuate bias in social systems.

Tracking group identity through natural language within groups

To what degree can we determine people's connections with groups through the language they use? In recent years, large archives of behavioral data from social media communities have become available to social scientists, opening the possibility of tracking naturally occurring group identity processes. A feature of most digital groups is that they rely exclusively on the written word. Across 3 studies, we developed and validated a language-based metric of group identity strength and demonstrated its potential in tracking identity processes in online communities. In Studies 1a-1c, 873 people wrote about their connections to various groups (country, college, or religion). A total of 2 language markers of group identity strength were found: high affiliation (more words like we, togetherness) and low cognitive processing or questioning (fewer words like think, unsure). Using these markers, a language-based unquestioning affiliation index was developed and applied to in-class stream-of-consciousness essays of 2,161 college students (Study 2). Greater levels of unquestioning affiliation expressed in language predicted not only self-reported university identity but also students' likelihood of remaining enrolled in college a year later. In Study 3, the index was applied to naturalistic Reddit conversations of 270,784 people in 2 online communities of supporters of the 2016 presidential candidates-Hillary Clinton and Donald Trump. The index predicted how long people would remain in the group (3a) and revealed temporal shifts mirroring members' joining and leaving of groups (3b). Together, the studies highlight the promise of a language-based approach for tracking and studying group identity processes in online groups.

Social media conversations reveal large psychological shifts caused by COVID-19's onset across U.S. cities

The current research chronicles the unfolding of the early psychological impacts of coronavirus disease 2019 (COVID-19) by analyzing Reddit language from 18 U.S. cities (200,000+ people) and large-scale survey data (11,000+ people). Large psychological shifts were found reflecting three distinct phases. When COVID-19 warnings first emerged (“warning phase”), people’s attentional focus switched to the impending threat. Anxiety levels surged, and positive emotion and anger dropped. In parallel, people’s thinking became more intuitive rather than analytic. When lockdowns began (“isolation phase”), analytic thinking dropped further. People became sadder, and their thinking reflected attempts to process the uncertainty. Familial ties strengthened, but ties to broader social groups weakened. Six weeks after COVID-19’s onset (“normalization phase”), people’s psychological states stabilized but remained elevated. Most psychological shifts were stronger when the threat of COVID-19 was greater. The magnitude of the observed shifts dwarfed responses to other events that occurred in the previous decade.

The Mediated Moderation Model of Depressive Symptoms, Alcohol Use, and Consequences: The Protective Role of Executive Function

Heavy episodic drinking (HED) and negative drinking consequences represent prevalent and serious health concerns for college students. Depressive symptoms may elevate students' risk for engaging in HED and experiencing negative consequences, but levels of risk may vary by executive function (EF) capabilities. Growing evidence suggests that EF deficits are associated with comorbid depressive symptoms and alcohol misuse. Nevertheless, little is known about unique and shared risks that depressive symptoms and EF may interactively pose for HED and negative drinking consequences. Methods: To address these gaps, the study assessed depressive symptoms, multiple domains of EF via multimethod approach, HED, and negative drinking consequences in a sample of 446 undergraduate students. Mediated moderation models were conducted to examine associations between depressive symptoms and alcohol use behaviors and modulating roles of EF. Results: Depressive symptoms, poor planning, and self-reported executive dysfunction were significantly associated with HED and negative drinking consequences. HED mediated the effect of depressive symptoms and executive dysfunction on negative consequences. A significant interaction indicated that better EF (i.e. low or average self-reported executive dysfunction) may buffer the risk depressive symptoms present for negative drinking consequences. Conclusions: The current findings suggest that among college students, risk and resilience factors for HED and negative drinking consequences may vary. Effective EF capabilities may be especially helpful for reducing students' risk for more serious drinking consequences.

How eating disordered and non-eating disordered women differ in their use (and effectiveness) of cognitive self-regulation strategies for managing negative experiences

PURPOSE

The present study compared the use (and effectiveness) of cognitive self-regulation strategies in eating disordered (ED) and non-eating disordered women (non-ED), and whether ED subgroups differ in their use of avoidant/suppressive strategies and cognitive reappraisal.

METHODS

The participants consisted of 90 adult patients recruited from a specialist eating disorder service and 97 adults without an ED. Cognitive self-regulation strategies were examined on a baseline self-report measure and while looking in a mirror.

RESULTS

The results of this study showed that, relative to the non-ED group, ED participants engage in more worry and self-punishment and less distraction and social control strategies in general but not specifically during a body exposure task. Reappraisal strategies were equally likely to be used by clinical and non-clinical groups but participants with anorexia nervosa (AN) found them less effective during the task. Non-ED participants found distraction strategies more effective than the ED group for managing the body exposure experience. ED subgroups used avoidant/suppressive strategies and cognitive reappraisal strategies to a similar extent.

CONCLUSION

The use of maladaptive self-regulation strategies, and the use and effectiveness of some of the more adaptive self-regulation strategies sets eating disorders apart from those without an eating disorder, supporting previous research in the area. Contrary to what was predicted, the results were similar across ED subgroups. The findings highlight the importance of cognitive self-regulation strategies as a focus of research and clinical intervention.

Establishing Immediate Reliability of Sonographic Measurements of the Transversus Abdominis in Asymptomatic Adults Performing Upright Loaded Functional Tasks in a Clinical Context Without Delayed Recorded Measurement

OBJECTIVES

This study examined the reliability of sonographic measurements of the transversus abdominis of adults without low back pain during upright loaded functional tasks in real time, without relying on delayed recorded images.

METHODS

A single-group repeated-measures reliability study was conducted on 12 healthy participants without low back pain. Six of these adults reported a prior history of abdominal drawing-in maneuver training without sonographic measurement. The participants performed 3 trials of neutral standing, a loaded forward reach, and a loaded box lift under rest and with abdominal drawing-in maneuver instructions; task order was randomized. Transversus abdominis thickness measurements were obtained by an experienced rater using B-mode sonography in real-time via electronic calipers twice on the same static image during all trials by a rater. The rater was masked to group assignment and on-screen measurement output and required to respond to trivia questions between repeated measurements.

RESULTS

The participants included 6 male and 6 female adults with a mean age ± SD of 26.3 ± 3.7 years. Intra-rater intraclass correlation coefficients (2,3) were high and precise for the rater's first and second measurements for all tasks and instruction conditions for mean transversus abdominis thickness and percent change in thickness measurements (eg, ranges were 0.968-0.997 for intraclass correlation coefficients, 0.01-0.21 mm for standard errors of the measurement, and 0.01-0.58 mm for minimal detectable changes). Calipers cleared by the rater or a research assistant produced similar findings of excellent reliability and precision.

CONCLUSIONS

High intra-rater reliability and precision of transversus abdominis thickness measurements were obtained by a physical therapist in real time from asymptomatic adults performing upright loaded functional tasks under rest and with abdominal drawing-in maneuver instructions.
