The Reading the Mind in the Eyes Test (RMET) is widely used in clinical and non-clinical research. However, the structural properties of RMET scores have yet to be rigorously examined. We analyzed the structural properties of RMET scores in nine existing datasets comprising non-clinical samples ranging from 558 to 9,267 (median = 1,112) participants each. We used confirmatory factor analysis to assess two theoretically derived factor models, exploratory factor analysis to identify possible alternative factor models, and reliability estimates to assess internal consistency. Neither of the theoretically derived models was a good fit for any of the nine datasets, and we were unable to identify any better fitting multidimensional models. Internal consistency metrics were acceptable in six of the nine datasets, but these metrics are difficult to interpret given the uncertain factor structures. Our findings contribute to a growing body of evidence questioning the reliability and validity of RMET scores.

In 2017, the #MeToo movement garnered international attention when millions of people used the hashtag to share personal experiences of sexual violence. The present study examines how noncelebrity users discussed their experiences of sexual victimization through a qualitative and quantitative content analysis of a random sample of #MeToo tweets (N = 1,427). We found that survivors prioritized details about the "who," "what," "where," "when," "why," and "how" of trauma in their disclosures. Key themes in their responses included child sexual abuse (22.7%), long-term adverse effects (17.6%), and polyvictimization (10.4%) across the life course. Survivors also utilized #MeToo to highlight the prevalence of violence against women (26.4%) and offer critiques of rape culture and social structures (23.9%) as indirect causes of their victimization and subsequent negative experiences. Our analysis demonstrates the utility of Twitter for broadening current understandings of the context in which sexual violence occurs, while also offering a nuanced analysis of the persisting difficulties many survivors face in narrating personal experiences of violence.

Youth with mental health and neurodevelopmental conditions may be at increased risk for interpersonal violence victimization and perpetration as compared to counterparts without these conditions. To investigate this possibility, we conducted an analysis using U.S. nationally representative data collected from youth ages 11 to 21 years old (N = 846). We calculated the prevalence of any dating abuse victimization or perpetration, as well as four specific subtypes of dating abuse-physical, sexual, psychological, and cyber dating abuse-for youth with eight types of mental health and neurodevelopmental disorders (i.e., anxiety, depression, post-traumatic stress disorder [PTSD], oppositional defiant or other conduct disorder, bipolar disorder [BD], attention deficit disorder/attention deficit hyperactivity disorder [ADHD], autism, or learning disability). Nearly one-half (43%) of the sample reported that they had one or more of the eight mental health or neurodevelopmental conditions (n = 337), 75% of those reported experiencing at least one act of dating abuse victimization in the past year, and 62% reported one or more acts of dating abuse perpetration. Ordinal regression model analyses demonstrated that youth with mental health and neurodevelopmental conditions had substantially elevated odds of more frequent physical, sexual, psychological, and cyber dating abuse victimization (adjusted odds ratios ranged from 1.2 to 7.4) and dating abuse perpetration (adjusted odds ratios ranged from 1.0 to 6.9) controlling for gender, sexual orientation, race, ethnicity, age, and household income. Compared to youth with no mental health or neurodevelopmental conditions, youth with BD were particularly likely to report more frequent experiences of all types of dating abuse victimization. Also, sexual dating abuse perpetration was elevated among youth with anxiety, depression, PTSD, BD, and ADHD. Funders are called upon to invest strategically in the development and rigorous testing of healthy relationships promotion programs and strategies that will benefit the millions of youth in U.S. schools who have these conditions.

Objectives: This study examined the role of caregivers' perception of cognitive impairment in burden of family caregivers in Alzheimer's disease (AD). We hypothesized that the evaluation of cognitive impairment by family caregivers plays a pivotal role in burden.

Methods: The study included 110 dyads (person with AD and their caregiver) recruited from a Memory Unit in France. The cognitive impairment and depressive symptoms of person with AD were evaluated by a geriatrician using the Mini Mental State Examination (MMSE) and the Geriatric Depression Scale (GDS-15). Caregivers provided self-reports on the perception of cognitive impairment (IQCODE) of the care recipient, the caregiving burden (ZBI), depressive symptoms (GDS-15), and self-esteem (RSE). Descriptive analyses, comparison of different caregiver burden groups, and multinomial logistic regression analyses to understand correlates of caregiver burden were conducted with SPSS^®, version 20.

Results: The findings show that the caregivers are on average 60 years old and the majority are women. They care for persons with AD, who are on average 82 years old and most of whom are women. Our results show that the duration of caregiving, depression of the caregiver, and caregivers' perception of cognitive impairment contribute significantly to burden of caregiver.

Discussion: This study shows that it is necessary to adopt the caregiver-centered approach to support the dyad. The role of the caregivers' perception of cognitive impairment in AD should be developed when supporting caregivers in suffering.

In Japan, the diagnostic criteria for the higher brain dysfunction (HBD) emerged in 2005 in response to social needs for support for the patients and their families. The issue of cognitive dysfunction after brain trauma is not unique to Japan. The purpose of this study was to reveal the current status of family members of HBD patients from their perspective, focusing on the changes before and after the establishment of diagnostic criteria in Japan. We conducted a questionnaire survey for family members supporting the HBD patients. The questionnaire included the causative condition, explanation on HBD by health professionals, and problems/difficulties they encountered. This research involved family members of 278 HBD cases (males = 211, age 49 years). The major underlying cause was head injury (n = 139). Compared to patients diagnosed pre-2005, a significantly larger proportion of family members after 2005 received information on the condition during the acute phase (within one month) (p < 0.001), including that from physicians (p < 0.001). Nearly half of the families cited a lack of awareness of HBD among the professionals as a problem. In Japan, awareness of HBD in the society is gradually increasing especially after the current diagnostic criteria were implemented, and there has been a steady increase over time in early diagnosis. Yet, there still remain those not appropriately diagnosed. To salvage those patients and the families left behind, we are suggesting several recommendations to further augment clinical practice and the healthcare systems in Japan.

Recent research suggests that neurocognitive deficits in patients with schizophrenia may increase the risk of developing cognitive biases. As such, we set out to determine this predictive relationship as it pertains to the development of a first-episode psychosis. We hypothesized that poorer performance in processing speed would be associated with jumping to conclusions and an externalizing bias. Poorer performance in working memory would be associated with belief inflexibility and jumping to conclusions, and poorer performance in attention would be associated with attention to threat. We hypothesized that all cognitive biases would be associated with subsyndromal positive symptoms, and schizotypal traits would moderate these relationships. Undergraduate students (N = 130) completed the Schizotypal Personality Questionnaire, DAVOS Assessment of Cognitive Biases, Community Assessment of Psychic Experiences, and a computerized neuropsychological assessment battery. Processing speed had a small effect on externalizing bias, which in turn affected subsyndromal positive symptoms. There was no moderating effect of schizotypal traits on externalizing bias, but it was significantly associated with subsyndromal positive symptoms. Only the externalizing bias was associated with subsyndromal positive symptomatology, which might be explained by a restricted range and reduced variance in performance as a result of using a university student sample. This is one of few studies that sought to explain the mechanism responsible for the development of subsyndromal positive symptoms in a healthy sample using self-report measures.

Objective: To reveal the discriminative value of gait parameters between Alzheimer's disease (AD) and Parkinson's disease (PD) subjects.

Methods: We included all consecutive patients with newly diagnosed AD and those with a diagnosis of PD who applied to our polyclinic between March 2022 and June 2022. The demographic and clinical features were evaluated during interviews. The gait analyses were performed using a quantitative, smartphone-based gait analyses program. Using this program, the step time (ST), step length (SL), step number (SN), gait velocity (GV), and cadence were measured in all individuals.

Results: Overall, 31 patients with AD and 45 with PD were enrolled in the analyses. The mean age of the AD group was higher according to those with PD. As expected, the Mini-Mental State Examination (MMSE) values were lower in the AD group. The comparative analyses of the gait parameters between groups did not reveal differences in any of the measures. The correlation analyses to investigate the possible association between the disease severity and gait parameters revealed that the MDS-UPDRS showed low negative correlations with SL and GV.

Conclusion: Our findings suggest that the evaluation of gait using the gait analyses program does not contribute to the discrimination between AD and PD in clinical practice.

This study compared the neuropsychological performance of two post-stroke groups, one undergoing rehabilitation and the other not receiving any intervention, on the acute and chronic stroke phases, and explored sociodemographic and neurological variables associated with changes in performance over time. Sixty-three adults underwent neuropsychological assessment with the Cognitive Screening Instrument (TRIACOG) less than thirty days after having a stroke and were reassessed three to six months after stroke. Thirty-eight participants did not undertake rehabilitation and twenty-five did physiotherapy and/or speech therapy between the two time points. The frequency of cognitive deficits (between groups) and the range of cognitive assessment scores over time (between and within groups) were analyzed. There was a significant decrease in the frequency of neuropsychological deficits and improvement on neuropsychological assessment scores over time only in the group undergoing rehabilitation. Severity of the neurological condition, years of education and being in rehabilitation explained the longitudinal changes in several cognitive domains measured by TRIACOG. Engaging in rehabilitation within three to six months post-stroke is crucial for enhancing the recovery of neuropsychological deficits. Cognitive screening instruments like TRIACOG can be used by health professionals to identify stroke-related neuropsychological changes and plan interventions.

Cognitive impairment and functional limitation are commonly observed in older adults. They have a complex correlation, and both are risk factors for mortality. This prospective cohort study aimed to explore the independent and joint impact of cognitive impairment and functional limitations on all-cause mortality in older adults. A total of 3,759 participants aged ≥ 60 years who had available information on mortality data, cognitive function, physical function, and covariates were enrolled. Cox proportional hazards regression models were employed to assess the independent and joint impacts of cognitive impairment and functional limitation on all-cause mortality. Smoothing curve fitting was used to show the nonlinear relationship between the Digit Symbol Coding (DSC) score and all-cause mortality. An interaction between cognitive impairment and functional limitation was identified when examining their associations with all-cause mortality. Cognitive impairment and functional limitation independently correlated with all-cause mortality risk even after adjusting for covariates and performing mutual adjustments (HR for cognitive impairment: 1.34, 95% CI 1.15-1.56; HR for functional limitation: 1.50, 95% CI 1.32-1.70). When the DSC score was > 18, as the score increased, the risk of death significantly decreased (HR 0.99, 95% CI 0.98-0.99). Participants with both cognitive impairment and functional limitation had the highest hazard ratio for all-cause mortality (HR 1.98, 95%CI 1.63-2.40). In summary, cognitive impairment and functional limitation independently correlated with increased all-cause mortality risk. A higher DSC score was a protective factor reducing the premature mortality risk. Older adults with cognitive impairment and functional limitation demonstrated the highest all-cause mortality risk.

ObjectiveInvestigators assessed whether a simplified runway status light (specifically runway entrance lights) may reduce the risk of runway incursions in nontowered airport environments.BackgroundComplementing the development of a low-cost aircraft surveillance system, the authors proposed the use of runway status lights at nontowered airports, an environment in which such systems have previously not been tested.MethodThirty-seven general aviation pilots were recruited to participate in three simulated scenarios with and without runway status lights. Participants were tasked with deciding when to take off from a runway. Participants' performance was assessed to determine whether simplified runway status lights impacted the risk of runway incursions, or how quickly a takeoff decision was made. The effect of the provision of system information on participants' performance was also studied. A NASA TLX questionnaire was administered to measure the perceived workload effects of runway status lights use while a survey captured participants' views on runway status light use.ResultsSimplified runway status lights reduced runway incursion risk in simulated scenarios when conflicting aircraft were relatively difficult to see. The provision of training or system information appeared desirable but not necessary, based on participants' feedback and performance. A reduction in perceived workload (physical domain) was reported in scenarios with runway status lights. Overall, participants had positive views on the implementation of runway status lights.ConclusionSimplified runway status lights may be effective at mitigating runway incursion risk.ApplicationThese findings support the continued study of runway status lights at more airports, including nontowered airports.
