ABSTRACT

At least one in three women experience intimate partner violence (IPV) in their lifetime. The most commonly sustained IPV-related brain injuries include strangulation-related alterations in consciousness (S-AICs) and traumatic brain injuries (TBIs). Moreover, survivors of IPV-related S-AICs and/or TBIs often demonstrate psychological distress such as depression, anxiety, and post-traumatic stress. However, the co-occurrence of S-AICs and TBIs, and whether such TBIs may be moderate to severe, has not been systematically examined, and most data have been collected from women in North America. The purpose of this study was to examine the co-occurrence of IPV-related S-AICs and TBIs across a range of geographical locations and to determine the extent to which these S-AICs are related to psychological distress. Women who had experienced physical IPV (N=213) were included in this secondary analysis of retrospectively collected data across four countries (Canada, USA, Spain, and Colombia). The Brain Injury Severity Assessment (BISA) was used to assess IPV-related BI across all sites. Because various questionnaires were employed to assess levels of depression, anxiety, and PTSD at each site, we created a standardized composite score by converting raw scores into Z-scores for analysis. Mann Whitney U tests and Chi square tests were conducted to examine differences between women with- versus without-experience of S-AICs and to discover if there was a relationship between the occurrence of S-AICs and TBIs. Analysis of variance, and analysis of covariance (to control for the potential confounding effects of age, education, and non IPV-related TBI) were used to compare levels of psychological distress in women who had or had not experienced S-AICs. Approximately 67% of women sustained at least one IPV-related BI (i.e., TBI and/or S-AIC). In a sub-sample of women who sustained at least one IPV-related BI, approximately 37% sustained both S-AICs and TBIs, 2% sustained only S-AICs (with no TBIs), and 61% sustained TBIs exclusively (with no S-AICs). Furthermore, women who had sustained S-AICs (with or without a TBI) were more likely to have experienced a moderate to severe BI than those who had not sustained an S-AIC (BISA severity subscale: U=3939, p=0.006). Additionally, women who experienced S-AICs (with or without a TBI) reported higher levels of psychological distress compared to women who never experienced S-AICs, irrespective of whether they occurred once or multiple times. These data underscore the importance of assessing for S-AIC in women who have experienced IPV and when present, to also assess for TBIs and the presence of psychological distress. Unfortunately, there were methodological differences across sites precluding cross-site comparisons. Nonetheless, data were collected across four culturally and geographically diverse countries, and therefore highlight IPV-related BIs as a global issue which needs to be aggressively studied with policies established and then implemented to address find.

ABSTRACT

Introduction: This study examined social perceptions and rejection towards fifteen mental illnesses, as well as a preliminary test of the SUBAR model, that hypothesized perceptions of both vital forces and burden would be negatively and positively related to social rejection, respectively. Methods: Using an online survey with participants from France (n = 952), social rejection was assessed using a feeling thermometer and a social distance scale, while social perceptions were measured using visual analog scales. Results: A stigma map for these different disorders is drawn up, revealing the social perceptions and levels of stigmatization specific to certain mental illnesses. Controlling for relevant social perceptions (i.e., danger, warmth, competence), we found that perception of burden was positively and significantly associated to social distance and negative feeling for 73% and 67% of mental illnesses, respectively. The perception of vital force was negatively and significantly related to social distance and negative feeling for 87% and 20% of mental illnesses, respectively. The change in R2 between model 1 (i.e. perception of danger, warmth, competence) and model 2 (i.e. model 1 + perceptions of vital force and burden) significantly improved in 100% of cases for social distance and 67% of cases for negative feeling. Conclusion: These preliminary data provide support for the SUBAR model and call for further investigations to better understand the social rejection of people with mental illnesses.

ABSTRACT

The rising demographic of older adults worldwide has led to an increase in dementia cases. In order to ensure the proper allocation of care and resources to this clinical group, it is necessary to correctly distinguish between simulated versus bona-fide cognitive deficits typical of dementia. Performance Validity Tests (PVTs) are specifically designed to assess a lack of effort and the possible simulation of cognitive impairment. Previous research demonstrates that PVTs may be sensitive to dementia, thus inaccurately classifying real memory impairment as simulation. Here, we analyzed the sensitivity of PVTs in discriminating between dementia and simulation using receiver operating characteristic (ROC) curve analyses. Further, we examined the potential need for adjusting cut-off scores for three stand-alone (Test of Memory Malingering, Rey-15 Item Memory Test, and Coin in Hand-Extended Version) and one embedded (Reliable Digit Span) PVT for Portuguese older adults with dementia. The results showed that (1) all measures, except for the Coin in Hand- Extended version (CIH-EV), were sensitive to one or more sociodemographic and/or cognitive variables, and (2) it was necessary to adjust cut-off points for all measures. Additionally, the Rey-15 Item Memory Test did not demonstrate sufficient discriminating capacity for dementia. These results present important implications for clinical practice and the daily life of patients, as the use of incorrect cut-off points could impede patients from getting the resources they need.

ABSTRACT

Introduction: Pregnancy has been associated with diminished maternal mental health and a deterioration in partner relationship quality. The recent COVID-19 quarantine measures have created additional stressors for pregnant women due to isolation and a surge in partner conflict.Objective: The purpose of this study was to assess how partner relationship conflict and social support may mediate mental health outcomes during the COVID-19 lockdown.Methods: A cross-sectional study with a sample of 152 pregnant women using psychological measures, (i.e. Prenatal Distress Questionnaire, Symptom Checklist-90-R, Duke-UNC-11 Functional Social Support Questionnaire, Perceived Stress Scale). Demographic characteristics, obstetrics history, and partner relationship conflict were assessed using questionnaires.Results: While there were few reports of physical violence in this sample, between 18% and 59% of women reported partner relationship conflict on the psychological subscale (e.g. afraid of one's partner or screamed at by one's partner). Further, the psychological subscale was significantly associated with symptoms of psychopathology. There was a significant negative association between social support and pregnancy-specific stress (p = .005), and perceived stress (p= .038).Conclusions: These findings suggest that partner relationship conflict and social support may act as important buffers for prenatal mental health in childbearing women during vulnerable situations, such as the COVID-19 pandemic.

ABSTRACT

OBJECTIVE: The aim of this work was to examine the relationship between strangulation-related alterations in consciousness (AIC) and cognitive and psychological outcomes in women who have experienced intimate partner violence (IPV). SETTING: Participants were recruited from a variety of settings, including women's shelters and support programs. PARTICIPANTS: A total of 99 women were enrolled in the study. After applying exclusion criteria for factors that could mask or confound the effects of strangulation, 52 women remained for analyses. DESIGN: Cross-sectional, retrospective. MAIN MEASURES: We used several cognitive measures to assess learning, long-term and working memory, visuomotor speed, cognitive flexibility, and nonverbal cognitive fluency as well as several psychological measures to assess posttraumatic stress symptomatology, general distress, worry, anhedonic depression, and anxious arousal. We also used the Brain Injury Severity Assessment interview to examine the association between strangulation-related AICs and these measures of cognitive and psychological functioning. RESULTS: Women who had experienced strangulation-related AICs performed more poorly on a test of long-term memory (P < .03) and had higher levels of depression (P < .03) and posttraumatic stress symptomatology (P < .02) than women who had not experienced strangulation-related AIC. When controlling for potential confounding variables, including number of IPV-related traumatic brain injuries, women who had experienced strangulation also performed more poorly on a measure of working memory. CONCLUSION: This is the first report to assess strangulation in this manner and demonstrate links to cognitive and psychological functioning. These preliminary data contribute to our knowledge of strangulation and its effects on women who have experienced IPV.

ABSTRACT

Intimate partner violence (IPV) has been related to brain alterations in female survivors. Nonetheless, few studies have used an exploratory approach, focusing on brain regions that are traditionally studied in other populations with post-traumatic stress. Traumatic brain injury (TBI), strangulation, and childhood trauma are highly prevalent among this population, and have also been associated with brain alterations and functional deterioration. As such, it is difficult to determine how different brain regions are affected by the complex interplay of these factors in female survivors. The aim of this study is to assess (a) brain alterations in female survivors of IPV as compared to non-victim females and (b) the potential causal mechanisms associated with such alterations. We hypothesized that structural brain differences would be found between female survivors of IPV and non-victims, and that these differences would be related to IPV-related TBI, strangulation, IPV severity, depression, post-traumatic stress, generalized anxiety, and childhood adverse experiences. A total of 27 non-victims and 28 survivors completed structural magnetic resonance imaging and questionnaires to measure the potential causal mechanisms for brain alterations. Structural brain differences were found between groups, principally in volumetric analyses. The brain regions in which between-group differences were found were related to attempted strangulation, IPV-related TBI, severity of IPV, adverse childhood experiences, and post-traumatic stress. These results demonstrate that a wider range of brain regions may be impacted by IPV and that various factors are implicated in the structural brain alterations found in female survivors. This study demonstrates the importance of post-traumatic stress, childhood and adult trauma, and physical violence in assessing brain alterations in IPV survivors. Further, it serves as a critical first step in assessing an extensive list of potential causal mechanisms for structural brain alterations, using a more comprehensive a whole-brain structural analysis of IPV female victims, a largely understudied and vulnerable population.

ABSTRACT

OBJECTIVE: The current study aimed to validate the Performance Validity Test Coin in Hand-Extended Version (CIH-EV) in groups of healthy older adults and older adults with dementia. METHOD: Using an analog simulation paradigm, the healthy control group and the clinical group were instructed to perform to the best of their ability, whereas the feigning older adults were instructed to simulate a memory deficit to obtain allowance, financial aid, or early retirement. RESULTS: Results showed that the control and clinical groups performed more optimally than the feigning group, although the clinical group had superior response times. The CIH-EV was insensitive to sociodemographic variables and neurocognitive functioning in all groups, demonstrated good convergent validity with other performance validity measures, and showed a reduced rate of false positives. CONCLUSIONS: This study corroborates the CIH-EV's effectiveness in detecting the simulation of cognitive deficits in healthy older adults and older adults with dementia.

ABSTRACT

Over the past decades European societies have become increasingly diverse. This diversity in culture, education, and language significantly impacts neuropsychological assessment. Although several initiatives are under way to overcome these barriers - e.g. newly developed and validated test batteries - there is a need for more collaboration in the development and implementation of neuropsychological tests, such as in the domains of social cognition and language.To address these gaps in cross-cultural neuropsychological assessment in Europe, the European Consortium on Cross-Cultural Neuropsychology (ECCroN) was established in 2019.ECCroN recommends taking a broad range of variables into account, such as linguistic factors, literacy, education, migration history, acculturation and other cultural factors. We advocate against race-based norms as a solution to the challenging interpretation of group differences on neuropsychological tests, and instead support the development, validation, and standardization of more widely applicable/cross-culturally applicable tests that take into account interindividual variability. Last, ECCroN advocates for an improvement in the clinical training of neuropsychologists in culturally sensitive neuropsychological assessment, and the development and implementation of guidelines for interpreter-mediated neuropsychological assessment in diverse populations in Europe.ECCroN may impact research and clinical practice by contributing to existing theoretical frameworks and by improving the assessment of diverse individuals across Europe through collaborations on test development, collection of normative data, cross-cultural clinical training, and interpreter-mediated assessment.

ABSTRACT

Objective: The validity of neuropsychological test performance has scarcely been studied in patients with substance use disorders (SUD), despite the possibility that some SUD individuals may distort their performance for compensation seeking (e.g., work leave, permanent or total disability, or the designation of services such as sheltered housing). Thus, the aim of the present study is to determine: (i) the possible utility of the Test of Memory Malingering (TOMM) in detecting invalid test results among SUD patients, and (ii) the percentage of individuals that underperform the TOMM among SUD patients seeking compensation.Method: Seventy-seven patients (59 men and 18 women) with SUD in outpatient treatment with an age range between 20 and 59 years were divided into two groups: SUD patients without compensation seeking (n = 41), and SUD patients with compensation seeking (n = 36). Participants performed a neuropsychological assessment with measures of processing speed, working memory, inhibition, verbal memory, cognitive flexibility, and decision-making, that also included the TOMM.Results: Our results demonstrate that there were no significant differences on TOMM performance between the two groups. Only one participant underperformed the TOMM (1.3% of the sample). Results showed cognitive impairment in the sample, but no differences between the groups on the different neuropsychological measures.Conclusions: This constitutes the first study to explore the capacity of a forced-choice test to detect invalid test results in an SUD population. There was a high performance on the TOMM among the SUD participants of our study despite their cognitive impairment, indicating adequate effort in their neuropsychological test performance. Further, these findings suggest that the probability of showing invalid neuropsychological performance among SUD compensation seeking patients is much lower than what has been found in other populations, such as in mild brain injury patients.

ABSTRACT

Mexican mothers have an important role in adolescent sexuality; however, they report multiple barriers to parent-child sex communication, which may impact adolescent sexual behaviour. This cross-sectional study examines whether adolescent perceptions of maternal barriers to communication are associated with adolescent sexual behaviour frequency indirectly through its association with maternal monitoring, and whether these associations differ by age and gender. Mexican adolescents (N = 1433), ages 12-19 (53% girls), completed a survey on normative sexual behaviours, adolescent perceptions of maternal barriers to sex communication, and maternal monitoring. Structural equation modelling analyses revealed that more barriers to communication (adolescent perceptions) were associated with more sexual behaviour frequency (i.e., oral and vaginal sex) among Mexican adolescents indirectly through its association with maternal monitoring. Findings were stronger for adolescents in 8th grades, but no differences were found by gender. This model expands our understanding of the parenting factors that impact Mexican adolescent sexuality.

ABSTRACT

The number of computerized and reliable performance validity tests are scarce. This study aims to address this issue by validating a free and computerized performance validity test: the Coin in Hand-Extended Version (CIH-EV). The CIH-EV test was administered in four countries (Colombia, Spain, Portugal, and the United States) and performance was compared with other commonly used validated tests. Results showed that the CIH-EV has at least 95% specificity and 62% sensitivity, and performance was highly correlated with scores on the Test of Memory Malingering, Victoria Symptom Validity Test, and Digit Span of the Wechsler Adult Intelligence Scale. There were no significant differences in scores across countries, suggesting that the CIH-EV performs similarly in a variety of cultures. Our findings suggest that the CIH-EV has the potential to serve as a valid validity test either alone or as a supplement to other commonly used validity tests.

ABSTRACT

Poor emotion processing is thought to influence violent behaviors among male batterers in abusive relationships. Nevertheless, little is known about the neural mechanisms of emotion processing in this population. With the objective of better understanding brain structure and its relation to emotion processing in male batterers, the present study compares the cortical grey matter thickness of male batterers to that of other criminals in brain areas related to emotion. Differences among these brain areas were also compared to an emotional perception task. An MRI study and an emotional perception assessment was conducted with 21 male batterers and 20 men convicted of crimes other than Intimate Partner Violence (IPV). Results demonstrated that batterers' had significantly thinner cortices in prefrontal (orbitofrontal), midline (anterior and posterior cingulate) and limbic (insula, parahipocampal) brain regions. The thickness of the dorsal posterior cingulate cortex in the batterer group correlated with scores on the emotional perception task. These findings shed light on a neuroscientific approach to analyzing violent behavior perpetrated by male batterers, leading to a better understanding of the underlying mechanisms involved in IPV.

ABSTRACT

Although the role of culture has increasingly gained acceptance in clinical neuropsychology, relatively minimal research exists regarding the actual impact on clinical activities. In this study, we assess how using North American neuropsychological tests affects diagnostic accuracy in cognitive disorders of culturally diverse individuals. To address this question, participants from Colombia, Morocco, and Spain were administered five commonly used neuropsychological tests and the test results were used to determine whether they would be classified as having the DSM-5 diagnostic criteria for Mild Cognitive and Major Cognitive Disorder. Results reveal that diagnostic error occurred up to 20% of the time, and that the frequency of misdiagnosis differed by nationality. These results provide evidence that using tests from one culture to assess individuals from other cultures produces significant false positives. Findings are discussed in terms of the foundations of neuropsychological assessment and its relationship to cultural variables.
