Relationship between Mental Health and Burden among Primary Caregivers of Outpatients with Schizophrenia

There is growing recognition that caring for a patient with schizophrenia often results in high levels of perceived burden and poorer overall mental health for caregivers. A quantitative cross‐sectional design and standardized instruments were used to collect data from 355 primary caregivers of adults in outpatient care with schizophrenia in China. Structural equation modeling was used to examine the association between caregiver burden and mental health among primary caregivers and whether this association is influenced by personality, coping style, and family functioning, based on a diathesis–stress perspective. Goodness‐of‐fit indices (χ²/df = 1.406, GFI = 0.919, CFI = 0.957, etc.) confirmed that the modified model fit the data well. In line with the diathesis–stress model, and with this study's hypotheses, we found that caregiver burden was significantly related to mental health outcomes directly. The final model showed that personality traits, coping style, and family function influenced the relationship between caregiver burden and mental health. The neuroticism personality traits have a direct effect on caregiver burden and family functioning in this sample. Coping style had a direct effect on the caregiver burden, and family functioning had a direct effect on the caregiver burden. Our final model about primary caregivers can be applied clinically to predict mental health outcomes from caregiver burden.     

Gait,balance, mobility and muscle strength in people with anxiety compared to healthy individuals

BackgroundAnxiety disorders are the most common mental disorders. Changes in psychomotor behavior can be observed in gross motor skills, with gait disturbances thought to reflect defective brain functions in psychiatric conditions. While balance deficits are well documented in anxiety, only little is known about gait characteristics of people with anxiety.ObjectiveThis study wishes to examine the existence of differences in gait, balance, mobility and muscle strength between people with anxiety and healthy individuals, and to investigate the relationship between level of anxiety and motor characteristics.MethodsAn observational study was conducted in a psychiatric out-patient unit at a large Israeli general hospital. The sample consisted of 93 participants, ages 18–65: 48 of them (27 female, 21 male) categorized as having anxiety, and 45 (25 female, 20 male) without anxiety. Participants were divided into two groups of various ages and both genders, and completed two questionnaires and four physical tests: objective anxiety assessment (Hamilton Anxiety Rating Scale); spatiotemporal gait parameters (10-meter walking test); balance function (Unipedal Stance Test); muscle strength evaluation, and mobility (Time Up and Go Test). No attempt was made to correlate between the anxiety and control groups based on age and/or gender.ResultsParticipants with anxiety (both genders) were characterized by slower walking speed, shorter step length, and fewer steps per minute (p < 0.001), as well as balance deficiency and mobility dysfunction (p < 0.001), compared to the control group. Muscle strength in women with anxiety was found to be significantly lower than in healthy women.ConclusionsTo the best of our knowledge, this study is the first of its kind to examine spatiotemporal gait components in patients with anxiety. Based on the findings, there is room to consider implementing gait analysis into the physical examination of patients with anxiety, as well as muscle strength, balance, and mobility function. Correct assessment and proper treatment of these aspects might contribute to the well-being of patients with anxiety.

Kernel principal component analysis combining rotation forest method for linearly inseparable data

Rotation forest (RoF) is an ensemble classifier combining linear analysis theories and decision tree algorithms. In recent existing works, RoF was widely applied to various fields with outstanding performance compared to traditional machine learning techniques, given that a reasonable number of base classifiers is provided. However, the conventional RoF algorithm suffers from classifying linearly inseparable datasets. In this study, a hybrid algorithm integrating kernel principal component analysis (KPCA) and the conventional RoF algorithm is proposed to overcome the classification difficulty for linearly inseparable datasets. The radial basis function (RBF) is selected as the kernel for the KPCA method to establish the nonlinear mapping for linearly inseparable data. Moreover, we evaluate various kernel parameters for better performance. Experimental results show that our algorithm improves the performance of RoF with linearly inseparable datasets, and therefore provides higher classification accuracy rates compared with other ensemble machine learning methods.     

Surviving the 2015 Mount Everest disaster: A phenomenological exploration into lived experience and the role of mental toughness

ObjectivesThe 2015 Nepal earthquake and subsequent avalanche at Mount Everest Base Camp is the deadliest mountaineering disaster to date. This study is novel in exploring the lived experiences of survivors and the role of mental toughness in their psychological responses to the disaster.DesignPhenomenological study.MethodTen mountaineers, who were on expeditions during the earthquake, participated in phenomenological interviews. Data were analysed inductively and thematically, while strategies to enhance trustworthiness were also employed.ResultsSeven dimensions emerged from the data, which captured climbers' psychological responses to the disaster, ranging from the moments the earthquake hit to reflections on the disaster after returning home. Contrasting emotional responses were described, and suggested to depend on experience and mental toughness. Negative emotional and behavioural responses were reported in the aftermath. Some climbers reported post-traumatic stress, but also a strong desire to return to Mount Everest and continue mountaineering.ConclusionsThese findings provide detailed insights into the lived experiences of climbers who survived the 2015 Nepal earthquake and Base Camp avalanche. Findings also shed light on the role of mental toughness in coping with and responding to a major natural disaster.     

Inter-brain co-activations during mindfulness meditation. Implications for devotional and clinical settings

Mindfulness meditation usually takes place as personal, introspective activity. It is not known if this practice activates the brain differently when done alone or with someone else.Sixteen couples of expert meditators performed mindfulness-oriented meditation (MOM) and instructed mind-wandering (IMW) tasks in two conditions: once sitting in the same room (SR) and once in two different rooms (DR). Spontaneous electroencephalographic (EEG) data was collected during 7-minute recording sessions in the four experimental settings (MOM/SR, MOM/DR, IMW/SR, IMW/DR). Power in band was computed in separate clusters of independent components of the EEG signals.In addition to significant task effects, found in frontolimbic (MOM > IMW in gamma) and frontoparietal locations (MOM < IMW in theta), significant condition effects were found in frontal (SR > DR in delta) and in temporo-occipital regions (SR > DR in theta and alpha). Moreover, a significant interaction between task and condition revealed higher gamma activity in limbic areas during MOM/SR vs. MOM/DR settings. This effect was not attributable to gender, age nor the meditation expertise of participants.We thus show that the brains of two people work differently when they are doing something together or alone; some of these differences are specific to mindfulness meditation. Implications for devotional and clinical settings are discussed.     

Question Design Affects Students' Sense-Making on Mathematics Word Problems

Mathematics word problems provide students with an opportunity to apply what they are learning in their mathematics classes to the world around them. However, students often neglect their knowledge of the world and provide nonsensical responses (e.g., they may answer that a school needs 12.5 buses for a field trip). This study examined if the question design of word problems affects students' mindset in ways that affect subsequent sense-making. The hypothesis was that rewriting standard word problems to introduce inherent uncertainty about the result would be beneficial to student performance and sense-making because it requires students to reason explicitly about the context described in the problem. Middle school students (N = 229) were randomly assigned to one of three conditions. In the standard textbook condition, students solved a set of six word problems taken from current textbooks. In the modified yes/no condition, students solved the same six problems rewritten so the solution helped answer a “yes” or “no” question. In the disfluency control condition, students solved the standard problems each rewritten in a variety of fonts to make them look unusual. After solving the six problems in their assigned condition, all students solved the same three “problematic” problems designed to assess sense-making. Contrary to predictions, results showed that students in the modified yes/no condition solved the fewest problems correctly in their assigned condition problem set. However, consistent with predictions, they subsequently demonstrated more sense-making on the three problematic problems. Results suggest that standard textbook word problems may be able to be rewritten in ways that mitigate a “senseless” mindset.     

‘Active’ating thoughts about affect: elicitation of physical activity judgements in insufficiently active women

Objective: A growing body of evidence suggests that affective judgements are distinct from, and exert greater influence on, physical activity behaviours than instrumental judgements.

Design: As part of a randomised controlled trial, 110 insufficiently active, female, university students were randomised to (a) an affective mental contrasting condition, (b) an instrumental mental contrasting condition, or (c) a ‘standard’ mental contrasting intervention (with no modifications). In the analyses concerning the trial’s primary outcome, the affective mental contrasting condition was found to be more effective for increasing physical activity than the standard or instrumental conditions. The purpose of this study was to qualitatively examine the physical activity outcomes and obstacles elicited from participants as part of the three mental contrasting interventions within this trial.

Results: 32 lower-order physical activity judgement themes, categorised within seven high-order themes, were derived through the use of the mental contrasting intervention. In addition to identifying several affective and instrumental outcomes and obstacles that have previously been recognised, participants in this study also highlighted contextualised responses that describe complicated relationships that exist between affective and instrumental judgements.

Conclusions: This study provides fine-grained insight into cognitive processes derived from a novel intervention involving insufficiently active women.     

Evidence for blatant dehumanization of mental illness and its relation to stigma

ABSTRACT

People with mental illness face stigma, and due to their low social status, they may also face blatant dehumanization that denies their status as fully evolved human beings. In the current research, three studies documented the existence of blatant dehumanization of mental illness. Study 1 (N = 112) showed that participants rated people with mental illness in general as being significantly less human than other dehumanized social groups such as Mexican immigrants and Muslims. Study 2 (N = 158) showed that dehumanization occurs for specific mental disorders but that the level of dehumanization varies widely among disorders. Study 3 (N = 223) documented significant correlations between dehumanization of mental illness and standard measures of stigma such as fear, pity, and social distance. Overall, the results establish the relevance of blatant dehumanization to mental illness stigma and suggest new directions for understanding stigma.
