Stress and emotion recognition predict the relationship between a history of maltreatment and sensitive parenting behaviors: A moderated-moderation.

Our study proposes to examine how stress and emotion recognition interact with a history of maltreatment to influence sensitive parenting behaviors. A sample of 58 mothers and their children aged between 2 and 5 years old were recruited. Parents' history of maltreatment was measured using the Child Trauma Questionnaire. An emotion recognition task was performed. Mothers identified the dominant emotion in morphed facial emotion expressions in children. Mothers and children interacted for 15 minutes. Salivary cortisol levels of mothers were collected before and after the interaction. Maternal sensitive behaviors were coded during the interaction using the Coding Interactive Behavior scheme. Results indicate that the severity of childhood maltreatment is related to less sensitive behaviors for mothers with average to good abilities in emotion recognition and lower to average increases in cortisol levels following an interaction with their children. For mothers with higher cortisol levels, there is no association between a history of maltreatment and sensitive behaviors, indicating that higher stress reactivity could act as a protective factor. Our study highlights the complex interaction between individual characteristics and environmental factors when it comes to parenting. These results argue for targeted interventions that address personal trauma.

Virtual reality compared with in vivo exposure in the treatment of social anxiety disorder: a three-arm randomised controlled trial.

BackgroundPeople with social anxiety disorder (SAD) fear social interactions and may be reluctant to seek treatments involving exposure to social situations. Social exposure conducted in virtual reality (VR), embedded in individual cognitive-behavioural therapy (CBT), could be an answer.AimsTo show that conducting VR exposure in CBT for SAD is effective and is more practical for therapists than conducting exposure in vivoMethodParticipants were randomly assigned to either VR exposure (n = 17), in vivo exposure (n = 22) or waiting list (n = 20). Participants in the active arms received individual CBT for 14 weekly sessions and outcome was assessed with questionnaires and a behaviour avoidance test. (Trial registration number ISRCTN99747069)ResultsImprovements were found on the primary (Liebowitz Social Anxiety Scale) and all five secondary outcome measures in both CBT groups compared with the waiting list. Conducting exposure in VR was more effective at post-treatment than in vivo on the primary outcome measure and on one secondary measure. Improvements were maintained at the 6-month follow-up. VR was significantly more practical for therapists than in vivo exposure.ConclusionsUsing VR can be advantageous over standard CBT as a potential solution for treatment avoidance and as an efficient, cost-effective and practical medium of exposure.

Using virtual reality to improve the efficacy of cognitive-behavioral therapy (CBT) in the treatment of late-life anxiety: preliminary recommendations for future research.

Cognitive-behavioral therapy (CBT) using traditional exposure techniques (i.e. imaginal and in vivo) seems less effective to treat anxiety in older adults than in younger ones. This is particularly true when imaginal exposure is used to confront the older patient to inaccessible (e.g. fear of flying) or less tangible/controllable anxiety triggers (e.g. fear of illness). Indeed, imaginal exposure may become less effective as the person gets older since normal aging is characterized by the decline in cognitive functions involved in the creation of vivid/detailed mental images. One way to circumvent this difficulty is to expose the older patient to a virtual environment that does not require the ability to imagine the frightening situation. In virtuo exposure has proven to be efficient to treat anxiety in working-age people. In virtuo exposure could be employed to improve the efficacy of CBT with exposure sessions in the treatment of late-life anxiety? The current paper explores this question and suggests new research avenues.

Subjective sleep quality in non-demented older adults with and without cognitive impairment.

OBJECTIVE: Sleep problems are prevalent among older adults who are at risk of developing dementia. Until now, there have been relatively few studies investigating subjective sleep quality in these individuals. The first objective of this study was to compare seniors with cognitive impairment no dementia (CIND) and older adults without cognitive impairment (non-CIND) on several subjective sleep measures. The second objective was to verify whether sleep parameters associated with CIND differ between men and women. METHODS: The population sample consisted of 2287 French-speaking older adults from Québec (Canada) aged between 65 and 96 years. Participants were classified as CIND or non-CIND on the basis of their mini mental state examination score using sex, age, and education-stratified normative data. All participants completed the Pittsburgh Sleep Quality Index, and responses of CIND and non-CIND individuals were compared. A series of confounding variables (age, education, chronic diseases, mood disorders, anxiety disorders, and use of psychotropic drugs) were statistically controlled for. Student's t-tests were performed to compare characteristics of CIND and non-CIND individuals; data from male and female participants were analyzed separately. Moreover, the association between each sleep variable and CIND was measured by odds ratios based on logistic regression. RESULTS: On the whole, analyses revealed no significant association between subjective sleep parameters and CIND. Moreover, no difference was observed between men and women regarding subjective sleep quality. CONCLUSIONS: Overall, these results suggest that subjective measures of sleep do not allow differentiating cognitively impaired older individuals from those with normal cognition.

Relationship between cortisol level and prevalent/incident cognitive impairment and its moderating factors in older adults.

BACKGROUND: The objectives of this study were to examine the factors modifying the relationship between cortisol level and prevalent/incident cognitive impairment in older adults and to verify whether these relationships were non-linear. METHODS: Data were collected from 1,226 individuals aged 65 and older by two in-home interviews separated by 12 months. Cortisol level was measured using saliva samples taken at the beginning of the baseline interview before cognitive, mental, and physical health evaluations. Prevalent and incident cognitive impairment were defined using the Mini-Mental State Examination scores according to normative data for age, education level, and sex. RESULTS: High morning cortisol level increased the risk of incident cognitive impairment in participants with anxiety or depressive episode while low cortisol level increased the risk in participants without anxiety or depressive episode. In high educated participants, but not in low educated participants, high morning cortisol level was associated with prevalent cognitive impairment and high afternoon cortisol level increased the risk of incident cognitive impairment. The results also suggested that lower morning cortisol values could increase the risk of incident cognitive impairment in individuals with few chronic diseases. A curvilinear relationship was observed between morning cortisol and the probability of incident cognitive impairment, but further analyses suggested that it was likely explained by anxiety and depressive episode. CONCLUSIONS: These results suggest that cognitive impairment in older adults is linked to higher or lower cortisol level depending on characteristics such as anxiety, depressive episode, education level, and physical health.

Pain in the eye of the beholder: Variations in pain visual representations as a function of face ethnicity and culture.

Pain experienced by Black individuals is systematically underestimated, and recent studies have shown that part of this bias is rooted in perceptual factors. We used Reverse Correlation to estimate visual representations of the pain expression in Black and White faces, in participants originating from both Western and African countries. Groups of raters were then asked to evaluate the presence of pain and other emotions in these representations. A second group of White raters then evaluated those same representations placed over a neutral background face (50% White; 50% Black). Image-based analyses show significant effects of culture and face ethnicity, but no interaction between the two factors. Western representations were more likely to be judged as expressing pain than African representations. For both cultural groups, raters also perceived more pain in White face representations than in Black face representations. However, when changing the background stimulus to the neutral background face, this effect of face ethnic profile disappeared. Overall, these results suggest that individuals have different expectations of how pain is expressed by Black and White individuals, and that cultural factors may explain a part of this phenomenon.

Prevalence of psychiatric disorders in community-dwelling older men and women with cognitive impairment no dementia: results from the ESA study.

OBJECTIVES: To assess the prevalence rate of mood disorders, anxiety disorders, benzodiazepine dependence, and insomnia in older men and women with probable cognitive impairment no dementia (CIND) and to examine the independent associations between each disorder and CIND. METHOD: Participants were a random sample of community-dwelling individuals aged 65-96 (N = 2414). Semi-structured in-home interviews based on DSM-IV-TR (DSM, Diagnostic and Statistical Manual of Mental Disorders) criteria evaluated the prevalence rates of mood disorders, anxiety disorders, benzodiazepine dependence, and insomnia. Participants were classified as probable CIND based on their Mini-Mental State Examination score using sex, age, and education-stratified cut-offs (lower than the 15th percentile). RESULTS: In men, 22.7% of individuals with probable CIND and 12.1% of those with normal cognition had at least one psychiatric disorder (crude odds ratio (OR): 2.13, 95% confidence interval (CI): 1.23-3.69). More specifically, mood disorders (3.43, 1.74-6.75), benzodiazepine dependence (5.10, 1.23-21.11), and comorbid anxiety and mood disorders (8.67, 2.00-37.68) were significantly associated with probable CIND, but not anxiety disorders alone and insomnia. The prevalence rate of psychiatric disorders was similar in women with probable CIND (23.1%) and in women without CIND (23.9%; 0.95, 0.64-1.42). No specific psychiatric disorder was significantly associated with probable CIND in women. All associations remained unchanged after adjustments for potential confounders. CONCLUSIONS: The association between psychiatric disorders and probable CIND appears to be sex-specific. In clinical practice, mood disorders, and benzodiazepine dependence should receive particular attention since these disorders are associated with a condition increasing the risk of dementia.

Arguing in Favor of Revising the Simulator Sickness Questionnaire Factor Structure When Assessing Side Effects Induced by Immersions in Virtual Reality.

Two issues are increasingly of interest in the scientific literature regarding unwanted virtual reality (VR) induced side effects: (1) whether the latent structure of the Simulator Sickness Questionnaire (SSQ) is comprised of two or three factors, and (2) if the SSQ measures symptoms of anxiety that can be misattributed to unwanted negative side effects induced by immersions in VR. Study 1 was conducted with a sample of 876 participants. A confirmatory factor analysis clearly supported a two-factor model composed of nausea and oculomotor symptoms instead of the 3-factor structure observed in simulators. To tease-out symptoms of anxiety from unwanted negative side effects induced by immersions in VR, Study 2 was conducted with 88 participants who were administered the Trier Stress Social Test in groups without being immersed in VR. A Spearman correlation showed that 11 out of 16 side effects correlated significantly with anxiety. A factor analysis revealed that items measuring general discomfort, difficulty concentrating, sweating, nausea, and vertigo loaded significantly on the anxiety factor comprised of items from the State-Trait Anxiety Inventory. Finally, a multiple regression indicated that the items measuring general discomfort and difficulty concentrating significantly predicted increases in anxiety. The overall results support the notion that side effects associated with immersions in VR consist mostly of a nausea and an oculomotor latent structure and that a few items are confounding anxiety and cybersickness. The data support the suggestion to revise the scoring procedures of the Simulator Sickness Questionnaire when using this instrument with immersions in VR.

Childhood maltreatment moderates the relationship between emotion recognition and maternal sensitive behaviors.

BACKGROUND: Sensitivity is defined as parents ability to perceive, react and respond to children signals. Having a history of childhood maltreatment changes the way adults perceive visual emotions. These perceptual characteristics could have important consequences on how these parents respond to their children. OBJECTIVE: The current study examines how a history of childhood maltreatment moderates the relationship between maternal emotion recognition in child faces and sensitive behaviors toward their child during free-play and a structured task. PARTICIPANTS AND SETTING: Participants included 58 mothers and their children aged between 2 and 5 years. METHODS: Mothers were exposed to a set of photographs of child faces showing morphed images of the six basic emotional expressions. Mother-child interactions were then coded for sensitive behaviors. Mothers' history of childhood maltreatment was assessed using the Childhood Trauma Questionnaire. RESULTS: Maltreatment severity was related to poorer abilities in emotion recognition. However, the association between emotion recognition and sensitive behavior was moderate by history of childhood maltreatment. For mothers exposed to a severe form of childhood maltreatment, a better emotion recognition was related to less sensitive behaviors toward the child, both during free-play and the structured task. CONCLUSION: This relationship is unique to these mothers and is inconsistent with Ainsworth's definition of sensitivity. These results have important implications as they suggest mothers with a history of severe maltreatment would need tailored interventions which take into account their particular reactions to children's emotions.

Chronic glucocorticoid hypersecretion in Cushing's syndrome exacerbates cognitive aging.

Cumulative exposure to glucocorticoid hormones (GC) over the lifespan has been associated with cognitive impairment and may contribute to physical and cognitive degeneration in aging. The objective of the present study was to examine whether the pattern of cognitive deficits in patients with Cushing's syndrome (CS), a disorder characterized by chronic exposure to elevated levels of glucocorticoids (GC), is similar to that observed in older individuals. Ten subjects with CS were compared to sex-, age-, and education-matched healthy controls and older subjects (age of CS subjects+15 yr). All participants were administered tests to assess attention, visuospatial processing, learning and memory, reasoning, concept formation and verbal fluency. MANCOVAs with depression scores as covariate and polynomial contrasts revealed that the age-matched control group performed better than the CS and older subject groups in visual target detection, trail making test, stroop task, digit symbol substitution, block design, object assembly, visual reproduction, spatial memory and similarities. The CS and older subjects performed similarly on these tasks. Further, a principal component analysis revealed two significant factors, representing general cognitive function and verbal memory explaining 39.9% and 10.0% of the variance, respectively. Additional MANCOVAs with depression as a covariate revealed that CS and older control subjects showed impaired performance on general cognitive function compared to age-matched controls. These results suggest that hypersecretion of GCs has "aging-like" effects on cognitive performance in individuals with CS.

The effect of acute social stress on the recognition of facial expression of emotions.

This study investigates the effect of acute social stress on the recognition of facial expression of emotions in healthy young men. Participants underwent both a standardized psychosocial laboratory stressor (TSST-G) and a control condition. Then, they performed a homemade version of the facial expressions megamix. All six basic emotions were included in the task. First, our results show a systematic increase in the intensity threshold for disgust following stress, meaning that the participants' performance with this emotion was impaired. We suggest that this may reflect an adaptive coping mechanism where participants attempt to decrease their anxiety and protect themselves from a socio-evaluative threat. Second, our results show a systematic decrease in the intensity threshold for surprise, therefore positively affecting the participants' performance with that emotion. We suggest that the enhanced perception of surprise following the induction of social stress may be interpreted as an evolutionary adaptation, wherein being in a stressful environment increases the benefits of monitoring signals indicating the presence of a novel or threatening event. An alternative explanation may derive from the opposite nature of the facial expressions of disgust and surprise; the decreased recognition of disgust could therefore have fostered the propensity to perceive surprise.

Long-term cognitive effects of glucocorticoid excess in Cushing's syndrome.

CONTEXT AND OBJECTIVE: We previously found that patients with Cushing's syndrome (CS) scored lower than controls in several domains of cognitive function and that correction of hypercortisolism is not necessarily correlated with short-term improvement in intellectual performance. Here, we examined the long-term outcome in patients treated for CS by assessing the extent to which the detrimental effects of glucocorticoid (GC) excess on cognition can be reversed three years after corrective surgery. DESIGN: A battery of neuropsychological tests, including tests of attention, visuospatial processing, learning and memory, and executive functioning were administered pre-treatment and 12, 24 and 36 months post-treatment. PATIENTS AND CONTROL SUBJECTS: We included 18 patients with endogenous CS recruited before surgical treatment and 18 controls matched for age, sex and education. RESULTS: CS patients performed worse than controls on tests of attention, executive functioning and nonverbal aspects of memory. Moreover, at 36 months following eucortisolism, executive function performance and, to a lesser extent, attention tasks showed limited change compared to pre-treatment testing. CONCLUSION: Chronic hypercortisolism is accompanied by a deleterious impact on aspects of cognitive function. This negative effect on attention, executive performance and nonverbal memory seen in patients with CS suggests a differential effect of excess GCs upon different brain areas and networks. This influence persists years after the return to normal cortisol secretion levels.

Cognitive function and cerebral assessment in patients who have Cushing's syndrome.

Cushing's syndrome (CS) is a relevant model to better understand the effects of glucocorticoid (GC) excess on the human brain. The importance of GC excess on the central nervous system is highlighted by the high prevalence of neuropsychiatric disorders such as depression and cognitive impairment in patients who have CS. In addition, there is a high incidence of apparent diffuse loss of brain volume in patients who have CS. Recent studies indicate at least partial reversibility of these abnormalities following correction of hypercortisolism.

Persistent cognitive impairment following surgical treatment of Cushing's syndrome.

Chronic exposure to elevated glucocorticoid (GC) levels in Cushing's syndrome (CS) is associated with deficits in cognitive function. It has already been shown that CS patients scored significantly lower than controls on several aspects of cognitive function (J. Int. Neuropsychol. Soc. 6 (2000) 20). In the present study, 13 subjects who presented with CS were investigated one year after surgical treatment to determine the extent to which the effects of hypercortisolism on cognitive function are reversible. Subjects were evaluated with a battery of tasks, similar to the original battery of a year earlier and including tests of attention, visuospatial processing, memory, reasoning and verbal fluency. Except for one task of visual organization, the results showed little change in performance, suggesting that prolonged exposure to high levels of GC can cause long-lasting deleterious effects on cognitive function. The data suggest that correction of hypercortisolism is not necessarily correlated with short-term improvement in cognitive function.

Usability Assessment of the Virtual Multitasking Test (V-MT) for Elderly People.

In the last decades an increasing number of psychological researches have used Virtual Reality (VR) technology in different fields. Nevertheless, few studies used Virtual Environments (VEs) with a sample of older users. The aim of the present study is to assess the usability of the Virtual Multitasking Test (V-MT), which consists in a virtual apartment created to assess cognitive functions in elderly people. This study reports the preliminary results to support the development of a VE in which elderly people feel present and fully immersed.

The dual nature of the human face: there is a little Jekyll and a little Hyde in all of us.

The fact that a mere glance makes it possible to extract a wealth of information about the person being observed is testament to both the salience of the human face and the brain's high efficiency in processing this information. Prior work has revealed that social judgments of faces are determined by facial features that vary on two orthogonal dimensions: trustworthiness and dominance. We conducted two experiments to investigate the visual information subtending trustworthiness and dominance judgments. In Experiment 1, we used the Bubbles technique to identify the facial areas and the spatial frequencies that modulate these two judgments. Our results show that the eye and mouth areas in high-to-medium spatial frequency bands were positively correlated with judgments of trustworthiness; the eyebrows region in medium-to-low frequency bands was positively correlated with judgments of dominance; and the lower left jawbone in medium-to-low frequency bands was negatively correlated with judgments of dominance. In Experiment 2, we used the results of Experiment 1 to induce subtle variations in the relative contrast of different facial areas, and showed that it is possible to rig social perception using such a manipulation.

Sleep quality and 1-year incident cognitive impairment in community-dwelling older adults.

STUDY OBJECTIVES: To examine in cognitively intact older men and women the associations between subjective sleep quality and 1-yr incident cognitive impairment. DESIGN: Prospective cohort study. SETTING: General community. PARTICIPANTS: 1,664 cognitively intact individuals age 65 to 96 years. MEASUREMENTS AND RESULTS: Sleep quality at baseline was measured using the Pittsburgh Sleep Quality Index (PSQI). Cognitive functioning was assessed at baseline and 12 months later using the Mini-Mental State Examination (MMSE). Incident general cognitive impairment was defined according to a follow-up MMSE score below the 15(th) percentile according to normative data and of at least 2 points below baseline. General cognitive impairments were also separated into amnestic and nonamnestic subtypes according to MMSE delayed recall performance. Associations between sleep quality indicators at baseline and incident cognitive impairment were assessed by odds ratio (OR) adjusted for age, education, baseline MMSE score, psychotropic drug use, anxiety, depressive episodes, cardiovascular conditions, and chronic diseases. Results revealed that global PSQI score was significantly linked with incident cognitive impairment (OR 1.17, 95% confidence interval (CI) 1.05-1.30) in men, but not in women. In women, sleep disturbance score (OR 2.62, 95% CI 1.41-4.86) and long sleep duration (≥ 9 hr; OR 3.70, 95% CI 1.49-9.17) were associated with nonamnestic and amnestic incident cognitive impairment, respectively. In men, short sleep duration (≤ 5 hr; OR 4.95, 95% CI 1.72-14.27) and habitual sleep efficiency score (OR 1.94, 95% CI 1.42-2.66) were associated with amnestic and general incident cognitive impairment, respectively. CONCLUSIONS: Sleep quality in older adults should receive particular attention by clinicians because poor sleep quality can be an early sign of cognitive decline.

Anxiety, depression, and 1-year incident cognitive impairment in community-dwelling older adults.

OBJECTIVES: To examine in men and women the independent associations between anxiety and depression and 1-year incident cognitive impairment and to examine the association of cognitive impairment, no dementia (CIND) and incident cognitive impairment with 1-year incident anxiety or depression. DESIGN: Prospective cohort study. SETTING: General community. PARTICIPANTS: Population-based sample of 1,942 individuals aged 65 to 96. MEASUREMENTS: Two structured interviews 12 months apart evaluated anxiety and mood symptoms and disorders according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. Incident cognitive impairment was defined as no CIND at baseline and a follow-up Mini-Mental State Examination score at least 2 points below baseline and below the 15th percentile according to normative data. The associations between cognitive impairment and anxiety or depression were assessed using logistic regression adjusted for potential confounders. RESULTS: Incident cognitive impairment was, independently of depression, associated with baseline anxiety disorders in men (odds ratio (OR)=6.27, 95% confidence interval (CI)=1.39-28.29) and anxiety symptoms in women (OR=2.14, 95%=1.06-4.34). Moreover, the results indicated that depression disorders in men (OR=8.87, 95%=2.13-36.96) and anxiety symptoms in women (OR=4.31, 95%=1.74-10.67) were particularly linked to incident amnestic cognitive impairment, whereas anxiety disorders in men (OR=12.01, 95%=1.73-83.26) were especially associated with incident nonamnestic cognitive impairment. CIND at baseline and incident cognitive impairment were not associated with incident anxiety or depression. CONCLUSION: Anxiety and depression appear to have different relationships with incident cognitive impairment according to sex and the nature of cognitive impairment. Clinicians should pay particular attention to anxiety in older adults because it may shortly be followed by incident cognitive treatment.
