Dimensionality of somatic complaints: factor structure and psychometric properties of the Self-Rating Anxiety Scale

The Effect and Mechanism of Adverse Childhood Experience on Suicide Ideation in Young Cancer Patients During Coronavirus Disease 2019 (COVID-19) Pandemic

Background and Aim

Coronavirus disease 2019 (COVID-19) is currently prevalent worldwide. This research aimed to explore the effect of adverse childhood experience (ACE) on suicide ideation in young cancer patients during the COVID-19 pandemic. Self-reported questionnaires analyzed the mediating effects of sleep quality, anxiety symptoms, and inflammatory conditions between ACE and suicide ideation.

Materials and Methods

A total of 197 young cancer patients (age 18–40) completed questionnaires and a blood test. Correlation analysis and structural equation model were used to explore the relationships between ACE, sleep quality, anxiety symptom, serum C-reactive protein (CRP) levels and suicide ideation. The mediating roles of sleep quality, anxiety symptoms, and CRP levels on the influence of ACE on suicide ideation were explored.

Results

ACE was positively related to anxiety symptoms, CRP levels, and suicide ideation, and negatively related to sleep quality. Anxiety symptoms and CRP levels were positively related to suicide ideation, while sleep quality was negatively related to suicide ideation. Anxiety symptoms were positively related to CRP levels but negatively related to sleep quality. From these results, we found ACE affected suicide ideation directly and was mediated by roles sleep quality, anxiety symptom and CRP.

Conclusion

ACE not only directly affected suicide ideation but also affected suicide ideation through sleep quality, anxiety symptoms, and inflammatory conditions in young cancer patients during the COVID-19 pandemic. Therefore, targeted intervention and help for cancer patients from the perspective of ACE should be put into practice.

Analysis of Psychological and Sleep Status and Exercise Rehabilitation of Front-Line Clinical Staff in the Fight Against COVID-19 in China

BACKGROUND The aim of this study was to understand the changes in psychological factors and sleep status of front-line medical staff in the fight against COVID-19 and provide evidence of exercise interventions to relieve psychological stress and improve sleep status for medical staff. MATERIAL AND METHODS A survey study was conducted among 120 front-line medical staff in the fight against COVID-19, of which 60 medical staff worked at the designated hospital (experimental group) and 60 medical staff worked at the non-designated hospital (control group). The Symptom Checklist 90 (SCL-90), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and PTSD Checklist-Civilian Version (PCL-C) were used to assess mental status. Sleep status was assessed using the Pittsburgh Sleep Quality Index (PSQI). RESULTS SCL-90 scores of somatization, depression, anxiety, and terror were higher than normal in front-line medical staff at the designated hospital. The SAS (45.89±1.117), SDS (50.13±1.813), and PCL-C (50.13±1.813) scores in the experimental group were higher than the normal control group, and were significantly different from those in the control group on SDS and PCL-C scales (P<0.05). The total average PSQI of the experimental group was 16.07±3.761, indicating that the sleep quality was poor. Among them, participants with moderate insomnia reached 61.67%, and participants with severe insomnia reached 26.67%. CONCLUSIONS There are psychological symptoms and sleep symptoms in front-line medical staff who participate in the fight against COVID-19, and they affect each other. Hospitals should improve emergency management measures, strengthen psychological counseling for clinical front-line medical staff, strengthen exercise intervention, and improve their sleep quality and mental health.

Association Between Alexithymia and Immature Coping Styles Is Mediated by Self-Inconsistency and Is Correlated to Obsessive-Compulsive Symptoms

This study aimed to investigate whether a multivariate association between alexithymia and coping styles is affected by self-inconsistency and whether the association contributed to obsessive-compulsive symptoms in 34 patients with obsessive-compulsive disorder (OCD) and 53 healthy participants. Alexithymia, coping styles, self-inconsistency, and obsessive-compulsive symptoms were evaluated using the Toronto Alexithymia Scale-20, the Coping Style Questionnaire, the Self-Consistency and Congruence Scale, and the Vancouver Obsessive-Compulsive Inventory, respectively. We found that self-inconsistency partially mediated the association between alexithymia and immature coping styles in the OCD patients but fully mediated the association in the healthy participants. Moreover, in the two groups, the alexithymia-coping coupling was related to contamination, obsession, indecisiveness, and ritualization, but not the checking symptom dimension. The findings suggest that the disturbance in identifying and describing feelings is associated with immature coping styles through disharmony between self-recognition and experience. The mechanism of the checking symptom seems to be distinct from other obsessive-compulsive symptoms.

Investigation of the psychological health of first-year high school students with myopia in Guangzhou

PURPOSE

The aim of this study was to investigate the differences in anxiety and depression between adolescents with myopia and those with normal vision and to examine the relationship between the level of anxiety and depression and the degree of myopia.

METHODS

A total of 1,103 first-year high school students aged 14-17 years were included in the study. The study group comprised 916 persons with myopia, while the control group comprised 187 persons without refractive error. Volunteers underwent routine eye examinations and completed a set of questionnaires about anxiety and depression. Then, the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores were compared between groups, and the relationships between anxiety and the degree of myopia and between depression and the degree of myopia were analyzed.

RESULTS

There was a significant difference in anxiety rate between the students with normal vision and those with myopia. The SAS scores among students with mild, moderate, and severe myopia were also significantly different. However, compared with the students with normal vision, the rate of depression was not significantly increased in the students with myopia, except in cases of severe myopia. Additionally, the SAS scores correlated closely with the diopters of the participants' glasses (r = 0.43, p = .045), while the relationship between SDS scores and the diopters of glasses was not significant (r = 0.19, p = .325).

CONCLUSION

There was a correlation between myopia and mental health in adolescent students, especially in terms of anxiety.

Social Capital and Sleep Quality in Individuals Who Self-Isolated for 14 Days During the Coronavirus Disease 2019 (COVID-19) Outbreak in January 2020 in China

Background

From the end of December 2019, coronavirus disease 2019 (COVID-19) began to spread in central China. Social capital is a measure of social trust, belonging, and participation. This study aimed to investigate the effects of social capital on sleep quality and the mechanisms involved in people who self-isolated at home for 14 days in January 2020 during the COVID-19 epidemic in central China.

Methods

Individuals (n=170) who self-isolated at home for 14 days in central China, completed self-reported questionnaires on the third day of isolation. Individual social capital was assessed using the Personal Social Capital Scale 16 (PSCI-16) questionnaire. Anxiety was assessed using the Self-Rating Anxiety Scale (SAS) questionnaire, stress was assessed using the Stanford Acute Stress Reaction (SASR) questionnaire, and sleep was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Path analysis was performed to evaluate the relationships between a dependent variable (social capital) and two or more independent variables, using Pearson’s correlation analysis and structural equation modeling (SEM).

Results

Low levels of social capital were associated with increased levels of anxiety and stress, but increased levels of social capital were positively associated with increased quality of sleep. Anxiety was associated with stress and reduced sleep quality, and the combination of anxiety and stress reduced the positive effects of social capital on sleep quality.

Conclusion

During a period of individual self-isolation during the COVID-19 virus epidemic in central China, increased social capital improved sleep quality by reducing anxiety and stress.

The Effects of Social Support on Sleep Quality of Medical Staff Treating Patients with Coronavirus Disease 2019 (COVID-19) in January and February 2020 in China

Background

Coronavirus disease 2019 (COVID-19), formerly known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and 2019 novel coronavirus (2019-nCoV), was first identified in December 2019 in Wuhan City, China. Structural equation modeling (SEM) is a multivariate analysis method to determine the structural relationship between measured variables. This observational study aimed to use SEM to determine the effects of social support on sleep quality and function of medical staff who treated patients with COVID-19 in January and February 2020 in Wuhan, China.

Material/Methods

A one-month cross-sectional observational study included 180 medical staff who treated patients with COVID-19 infection. Levels of anxiety, self-efficacy, stress, sleep quality, and social support were measured using the and the Self-Rating Anxiety Scale (SAS), the General Self-Efficacy Scale (GSES), the Stanford Acute Stress Reaction (SASR) questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and the Social Support Rate Scale (SSRS), respectively. Pearson’s correlation analysis and SEM identified the interactions between these factors.

Results

Levels of social support for medical staff were significantly associated with self-efficacy and sleep quality and negatively associated with the degree of anxiety and stress. Levels of anxiety were significantly associated with the levels of stress, which negatively impacted self-efficacy and sleep quality. Anxiety, stress, and self-efficacy were mediating variables associated with social support and sleep quality.

Conclusions

SEM showed that medical staff in China who were treating patients with COVID-19 infection during January and February 2020 had levels of anxiety, stress, and self-efficacy that were dependent on sleep quality and social support.

Physical activity and blood pressure during pregnancy: Mediation by anxiety symptoms

BACKGROUND

During pregnancy, physiological systems and psychological perceptions vary across individuals. Prenatal physical activity has been linked to reduced anxiety symptoms and lower blood pressure values. However, whether anxiety symptoms can mediate the relationship between physical activity and blood pressure during pregnancy remains unclear.

METHODS

In this prospective cohort study, 1275 pregnant women enrolled in Nanjing, China. Life behaviours and anxiety symptoms were investigated during the first trimester. Anxiety symptoms were measured by the Self-Rating Anxiety Scale. Blood pressure values were taken during the third trimester. Multivariate linear regression models were used to estimate the associations of physical activity with anxiety symptoms and blood pressure, and mediating effect models were used to detect the regulating effect by anxiety.

RESULTS

The participants were assigned to 3 groups based on their frequency and intensity of physical activity, and those who engaged in regular physical activity had lower blood pressure values. Anxiety symptoms were milder in the regular group than in the insufficient group. Partial mediating effect of anxiety on the association between regular physical activity and systolic blood pressure was significant after accounting for some confounders.

LIMITATIONS

The participants' physical activity and anxiety symptoms were self-reported, as well as the lack of details of physical activity during pregnancy may restrict the power of our findings.

CONCLUSIONS

Regular physical activity might be beneficial for anxiety and blood pressure. Physical activity likely stabilises systolic blood pressure by alleviating anxiety symptoms. Our research could provide a positive theoretical reference for guiding prenatal care.

Depression, Anxiety, Psychological Symptoms and Health-Related Quality of Life in People Living with HIV

OBJECTIVE

To investigate the levels of depression, anxiety, psychological symptoms and health-related quality of life (HRQOL) in people infected with human immunodeficiency virus (HIV) and to assess the risk factors.

METHODS

A total of 121 people living with HIV (PLWHIV) were included, and 61 health individuals were selected as healthy controls. Their sociodemographic information was collected. The Self-Rating Depression Scale, Self-Rating Anxiety Scale, Symptom Checklist 90 and Short-Form Health Survey-36 were used.

RESULTS

The depression score was higher in PLWHIV (47.83 ± 10.58 vs 36.52 ± 9.69 P<0.001). Similar results were observed in anxiety score (41.06 ± 11.24 vs 32.31 ± 7.99, P<0.001). Multivariable analysis revealed that younger age (OR=0.929, P=0.004) and smoking (OR=4.297, P=0.001) were identified as independent factors of depression while young age (OR=0.890, P=0.008) and alcohol consumption (OR=4.801, P=0.002) were independent factors of anxiety. Results of SCL-90 questionnaire showed that hostility, paranoia ideation were significantly more pronounced when PLWHIV had depression. Results of HRQOL showed that physical functioning (82.88 ± 14.73 vs 93.41 ± 9.22, P<0.001) and mental health (57.46 ± 17.64 vs 65.68 ± 17.44, P=0.012) were lower in PLWHIV with depression. For PLWHIV with anxiety, vitality (56.96 ± 14.61 vs 67.58 ± 17.57, P=0.004), social functioning (64.52 ± 23.97 vs 74.64 ± 21.47, P=0.036) and mental health (52.57 ± 14.21 vs 65.03 ± 17.98, P=0.001) were lower. High depression level was showed the independent risk factor associated with poor HRQOL (OR=0.370, P=0.001).

CONCLUSION

Depression and anxiety were very common in PLWHIV. Physicians should not only focus on the antiviral treatment of these patients but also monitor their mental status, especially that of younger patients. For PLWHIV with depression and anxiety, psychological intervention should be provided, and social role rebuilding may be good for depression and anxiety alleviation.

Auricular acupressure for cancer-related fatigue during lung cancer chemotherapy: a randomised trial

Purpose

To evaluate the effect of auricular acupressure (AA) on cancer-related fatigue (CRF), sleep disturbance and anxiety in lung cancer patients undergoing chemotherapy.

Materials and methods

Patients were recruited from the respiratory department of a general hospital and were randomised into three groups. A 9-week course of AA using Semen Vaccariae (SV) (Group A)/AA using magnetic beads (Group B)/routine care (Group C) was implemented. CRF scores were used as the primary outcome while the sleep and anxiety scores were the secondary outcomes. Analysis of variance and least significant difference t-test were used to determine the intergroup differences and paired-sample t-test was used for the intragroup comparison.

Results

100 lung cancer patients undergoing chemotherapy were included. Compared with Group C, AA could significantly alleviate CRF (F:24.63, p<0.01), especially for physical and affective fatigue and Group A was more effective for managing physical fatigue than Group B in per-protocol (PP) (−1.75 (−2.69 to –0.82), p<0.01)/Intention to Treat analysis (ITT) (−1.41 (−2.39 to –0.41), p=0.01) analysis. However, AA had no effect on cognitive fatigue. Compared with Group C, only Group A produced significant improvements in sleep quality in PP analysis (−1.17 (−2.23 to –0.10), p=0.03) while it yielded negative results in ITT analysis (−0.82 (−1.74 to 0.10), p=0.08). Compared with Group C, AA could significantly reduce anxiety in PP analysis (F:9.35, p<0.01) while there was no statistical difference between Group B and Group C (−0.95 (−2.81 to 0.90), p=0.31), Group A and Group B (−1.26 (−3.12 to 0.59), p=0.18) in ITT analysis.

Conclusion

AA can alleviate CRF of lung cancer patients undergoing chemotherapy, especially for physical and affective fatigue. AA using SV is more effective for physical fatigue while AA using magnetic beads works better for anxiety. However, AA cannot improve the sleep quality.

Association between hot flashes severity and oxidative stress among Mexican postmenopausal women: A cross-sectional study

Objective

To assess the association between hot flashes (HFs) severity and oxidative stress (OS) in Mexican postmenopausal women.

Methods

A cross-sectional study was carried out with perimenopausal women aged 40–59 years community-dwelling from Mexico City, Mexico. They participated in Menopause and Oxidative Stress Project. The baseline sample consisted of 476 women recruited to participate; 161 women were excluded due to different reasons. Hence, 315 women were selected to establish two groups, a) 145 premenopausal women (yet with menstrual bleeding), and b) 170 postmenopausal women (without menses). All women were free of cardiovascular, kidney, hepatic or cancer disease, and without antioxidant supplement intake for at least six months prior to the beginning of the study; none had previously received hormone therapy. As OS markers, we measured plasma malondialdehyde using the TBARS assay, erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GPx), uric acid, and total antioxidant status; also, we calculated SOD/GPx ratio, antioxidant gap and an oxidative stress score ranging from 0 to 7. The HFs were evaluated using the Menopause Rating Scale. The women completed Spanish version of the Athens Insomnia Scale, Zung Self-Rating Anxiety Scale and Zung Self-Rating Depression Scale and a questionnaire of pro-oxidant factors.

Results

Stress score increased with HFs severity (mild 2.7±0.17, moderate 2.9±0.20 and severe 3.7±0.20, p = 0.001) in postmenopausal women. We observed a positive correlation between HFs severity and stress score, r = 0.247 (p = 0.001) in postmenopausal women; other test scores were not correlated. Severe HFs were a risk factor for OS (OR = 5.12, 95%CI: 1.99–13.17, p<0.05) in an adjusted multivariate analysis by different postmenopausal symptoms and pro-oxidant factors; we did not see any association in premenopausal women.

Conclusion

Our findings suggest an association between HFs severity and OS in Mexican postmenopausal women.

Dynamic change of depression and anxiety after chemotherapy among patients with ovarian cancer

Psychological state of patients with ovarian cancer is worthy of attention. We aimed to investigate the levels of anxiety and depression in patients with ovarian cancer. We also investigated the dynamic changes in anxiety and depression levels after chemotherapy.A total of 228 females were included in this study. Among them, a total of 111 participants had ovarian cancer and 117 females who underwent a physical examination were selected as healthy controls. All patients enrolled were asked to fill in the Self-rating Depression Scale and the Self-rating Anxiety Scale. For patients with ovarian cancer, repeat questionnaires were measured after cycle 1 chemotherapy.The depression score of patients with ovarian cancer was 45.90 ± 10.19, significantly higher than in controls (36.08 ± 9.06, P < .001). Similar results were observed in respect of anxiety score. The score of ovarian cancer patients was 39.53 ± 12.92, significantly higher than of controls (32.15 ± 7.44, P < .001). Multivariate analyses were conducted, and the results showed that young age was the independent risk factor associated with depression among patients with ovarian cancer, while young age and singleness were the independent risk factors associated with anxiety. Repeat questionnaires were measured after chemotherapy. Interestingly, we found depression scores decreased from 45.90 ± 10.19 to 36.29 ± 8.98 after chemotherapy (P < .001), while anxiety score increased from 39.53 ± 12.92 to 42.75 ± 9.96 after chemotherapy (P = .009). Multivariate analysis suggested that only higher income and higher baseline depression score were the independent and most relevant risk factors associated with depression remission after chemotherapy. For patients with anxiety remission, only higher baseline anxiety score was the independent risk factor associated with anxiety remission.This study suggests that for patients with ovarian cancer, timely monitoring of the patient's psychological state, especially before and after chemotherapy treatment, is very important. Assessing the changes in the patient's psychological state, screening the population with risk factors, and prompt intervention by mobilizing social support may be effective in preventing depression and anxiety in such population.

Emotion Regulation of Hippocampus Using Real-Time fMRI Neurofeedback in Healthy Human

Real-time functional magnetic resonance imaging neurofeedback (rtfMRI-NF) is a prospective tool to enhance the emotion regulation capability of participants and to alleviate their emotional disorders. The hippocampus is a key brain region in the emotional brain network and plays a significant role in social cognition and emotion processing in the brain. However, few studies have focused on the emotion NF of the hippocampus. This study investigated the feasibility of NF training of healthy participants to self-regulate the activation of the hippocampus and assessed the effect of rtfMRI-NF on the hippocampus before and after training. Twenty-six right-handed healthy volunteers were randomly assigned to the experimental group receiving hippocampal rtfMRI-NF (n = 13) and the control group (CG) receiving rtfMRI-NF from the intraparietal sulcus rtfMRI-NF (n = 13) and completed a total of four NF runs. The hippocampus and the intraparietal sulcus were defined based on the Montreal Neurological Institute (MNI) standard template, and NF signal was measured as a percent signal change relative to the baseline obtained by averaging the fMRI signal for the preceding 20 s long rest block. NF signal (percent signal change) was updated every 2 s and was displayed on the screen. The amplitude of low-frequency fluctuation and regional homogeneity values was calculated to evaluate the effects of NF on spontaneous neural activity in resting-state fMRI. A standard general linear model (GLM) analysis was separately conducted for each fMRI NF run. Results showed that the activation of hippocampus increased after four NF training runs. The hippocampal activity of the experiment group participants was higher than that of the CG. They also showed elevated hippocampal activity and the greater amygdala–hippocampus connectivity. The anterior temporal lobe, parahippocampal gyrus, hippocampus, and amygdala of brain regions associated with emotional processing were activated during training. We presented a proof-of-concept study using rtfMRI-NF for hippocampus up-regulation in the recall of positive autobiographical memories. The current study may provide a new method to regulate our emotions and can potentially be applied to the clinical treatment of emotional disorders.

Psychometric Properties of the SAS, BAI, and S-AI in Chinese University Students

Three widely-used self-report anxiety scales, including the Self-Rating Anxiety Scale (SAS), the Beck Anxiety Inventory (BAI), and the State Anxiety Inventory (S-AI), were used to simultaneously compare the psychometric properties via an item response theory (IRT) model with Chinese university students as the sample. Although these scales were probably to measure the same underlying construct, namely, anxiety, their psychometric properties were different. Results showed that the BAI's measurement error was fewer than that of the other scales, with their anxiety severity ranging approximately from the 0.8 standard deviations below the mean to 3 standard deviations above the mean, while the S-AI's measurement error was fewer than that of the other degrees of anxiety. The S-AI provided more information than the other scales when the student's scale was less than approximately 0.8 standard deviations below the mean of anxiety severity. In general, the BAI showed better, for it provided more information than the other scales at the broadest range of anxiety severity. The SAS provided less information than the other scales at all anxiety severity range. In conclusion, BAI shows good psychometric quality. Finally, the three instruments were combined on a common scale by using IRT model and a conversion table was provided so as to achieve the transformation of each scale score.

Longitudinal characteristics of resilience among adolescents: A high school student cohort study to assess the psychological impact of the Great East Japan Earthquake

AIM

Resilience, the ability to cope with disasters and significant life adversity, is an important factor to consider when studying the mental health of populations affected by a disaster. Although high school students in a community affected by a disaster should have specific characteristics of resilience, little has been reported on the issue. This study was designed to provide initial data regarding characteristics of the resilience of high school students affected by a catastrophe.

METHODS

A total of 760 high school students in Natori City, which was devastated by the Great East Japan Earthquake in 2011, were profiled, and a 3-year longitudinal study was conducted with 254 students who had entered the school in 2012. Resilience was evaluated with the 10-item Connor-Davidson Resilience Scale. The Quick Inventory of Depressive Symptomatology-Japanese version, the Zung Self-Rating Anxiety Scale, and the Impact of Event Scale-Revised were also administered to assess the students' mental health.

RESULTS

Among the students who entered the high school in 2012, 28.6% showed high resilience, and the proportion increased to 42.9% in 2013 and 46.6% in 2014. The Quick Inventory of Depressive Symptomatology-Japanese version and Impact of Event Scale-Revised scores decreased significantly over the 3-year study period, but there were no significant differences in the Zung Self-Rating Anxiety Scale scores over time.

CONCLUSION

This initial study profiling the characteristics of resilience among adolescents suggests that resilience is a highly changeable component of mental health among people who have faced adversity. Resilience can be a useful indicator of recovery from adversity and a target of interventions for improving mental health conditions.

Moderating role of positive aspects of caregiving in the relationship between depression in persons with Alzheimer's disease and caregiver burden

Improving caregivers' positive perception of their role may be important in reducing their subjective burden when caring for Alzheimer's disease (AD) patients with depression. The purpose of present study was to explore the moderating role of the positive aspects of caregiving (PAC) on the subjective burden on family caregivers when managing depressive behaviors. We conducted a cross-sectional study including 200 pairs of patients with mild AD and their caregivers from three communities and two hospitals in Taiyuan, China in October 2014. The latent variable interaction model based on a two stage least squares (2SLS) regression was fitted. A significant moderating effect of the PAC was found on the relationship between depression in patients with AD and the caregiver burden they cause. Caregivers dealing with patients with low levels of depression but with high levels of the PAC had significantly lower levels of caregiver burden compared to those caregivers with the low levels of PAC. Continuously detecting the patient's mental state combined with caregivers having an optimistic attitude towards life may improve the quality of life for both patients and caregivers.

Quantifying absolute glutamate concentrations in nucleus accumbens of prescription opioid addicts by using 1H MRS

INTRODUCTION

The diagnosis of psychoactive substance use disorders has been based primarily on descriptive, symptomatic checklist criteria. In opioid addiction, there are no objective biological indicators specific enough to guide diagnosis, monitor disease status, and evaluate efficacy of therapeutic interventions. Proton magnetic resonance spectroscopy (¹H MRS) of the brain has potential to identify and quantify biomarkers for the diagnosis of opioid dependence. The purpose of this study was to detect the absolute glutamate concentration in the nucleus accumbens (NAc) of patients with prescription opioid dependence using ¹H MRS, and to analyze its clinical associations.

METHODS

Twenty patients with clinically diagnosed definitive prescription opioid dependent (mean age = 26.5 ± 4.3 years) and 20 matched healthy controls (mean age = 26.1 ± 3.8 years) participated in this study. Patients were evaluated with the Barratt Impulsiveness Scale (BIS-11), the Self-Rating Anxiety Scale (SAS), and the opiate Addiction Severity Inventory (ASI). We used point-resolved spectroscopy to quantify the absolute concentrations of metabolites (glutamate, choline, N-acetylaspartate, glutamine, creatine) within the NAc. The difference between metabolite levels of groups and Pearson's correlation between glutamate levels and psychometric scores in patients were analyzed statistically.

RESULTS

Glutamate concentrations in the NAc were significantly higher in prescription opiate addicts than in controls (t = 3.84, p = .001). None of the other metabolites differed significantly between the two groups (all ps > .05). The glutamate concentrations correlated positively with BIS-11 scores in prescription opiate addicts (r = .671, p = .001), but not with SAS score and ASI index.

CONCLUSIONS

Glutamate levels in the NAc measured quantitatively with in vivo ¹H MRS could be used as a biomarker to evaluate disease condition in opioid-dependent patients.

Illness uncertainty and illness intrusiveness as predictors of depressive and anxious symptomology in college students with chronic illnesses

OBJECTIVE

To examine predictors of psychological functioning in college students with chronic illnesses.

PARTICIPANTS

Participants (N = 1413) included 364 students with self-reported diagnoses of asthma or allergies, 148 students with other chronic illnesses (eg, epilepsy, type 1 diabetes), and 901 healthy students. Data were collected between November 2013 and May 2015.

METHODS

Participants completed online measures of psychosocial functioning, including illness uncertainty, illness intrusiveness, depression, and anxiety.

RESULTS

Students with chronic illnesses other than asthma or allergies evidenced the greatest levels of anxious (p <. 05), but not depressive symptomology. Additionally, this group reported greater illness uncertainty and intrusiveness (p <. 05) compared to their peers. Uncertainty and intrusiveness independently predicted depressive and anxious symptoms for students in both illness groups.

CONCLUSIONS

Compared to peers with asthma or allergies, college students with other chronic illnesses reported higher levels of anxious symptoms. Illness uncertainty and intrusiveness appear to be predictors of psychological distress, regardless of illness.

Exposure to stress across the life course and its association with anxiety and depressive symptoms: Results from the Australian Women's Wellness After Cancer Program (WWACP)

OBJECTIVES

Earlier life stressors can increase the risk of persistent anxiety and depressive symptoms in women after cancer, though our understanding of the underlying mechanisms is limited. In this study, we tested alternative life course models to determine which best described associations between exposure to stressors in childhood, adolescence, and adulthood, and self-reported health in women previously treated for breast, gynaecological, and blood cancer.

STUDY DESIGN

Data were drawn from 351 Australian women within 2 years of completing active cancer treatment who were participating in the Women's Wellness After Cancer Program (WWACP) randomised controlled trial. A model-building framework compared "accumulative risk" and "sensitive period" stress exposure hypotheses with the saturated model to determine best fit.

MAIN OUTCOME MEASURES

Symptoms of anxiety and depression were measured using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Zung Self-rating Anxiety Scale (SAS).

RESULTS

Participants with the greatest number of stressful life events (SLEs) reported higher anxiety scores and more depressive symptoms. Alternative life course models for psychological distress (measured through the CES-D and SAS) and stress were compared with the saturated model (i.e., the accumulative risk). The more restrictive "sensitive period" models were the best fit for depressive symptoms though none was significantly better than another. In contrast, an "early sensitive" model provided the best fit for anxiety data.

CONCLUSIONS

Anxiety scores were higher in women with early life stressors. This study highlights the need for whole-of-life supportive care approaches for women previously treated for cancer, which should include targeted strategies for effective management of stress, anxiety and depression.

Abnormal amplitude of low-frequency fluctuations associated with rapid-eye movement in chronic primary insomnia patients

Purpose

Chronic primary insomnia (CPI) is the most prevalent sleep disorder worldwide. CPI manifests as difficulties in sleep onset, maintaining sleep, prolonged sleep latency, and daytime impairment and is often accompanied by cognitive problems such as poor academic performance, poor attention, and decreased memory. The most popular explanation of insomnia is hyperarousal or increased activities of neurons. Rapid eye movement (REM) sleep detected by polysomnography (PSG) exhibits a positive relationship with brain homeostasis and can be helpful for optimally preparing an organism for emotional and social function. Limited work has been performed to explore brain function of insomnia patients in combination with PSG analysis.

Results

We observed increased ALFF within areas related to hyperarousal such as the midbrain and bilateral extra-nucleus, whereas decreased ALFF was observed within areas associated with memory and attention involving the parietal and occipital lobule and others. Furthermore, the altered ALFF was associated with the duration of insomnia, sleep efficiency, duration of REM, latency of RME and ratio of REM.

Materials and Methods

In this study, we recruited twenty-five CPI patients and twenty-five normal sleep (NS) volunteers as a control group to investigate the amplitude of low-frequency fluctuations (ALFF) and the correlation between those altered ALFF regions through resting-state fMRI and PSG data.

Conclusions

These findings suggest that hyperarousal reflected by ALFF abnormality within brain areas related to cognition and emotion in insomnia associated with REM sleep.

Effects of Sleep Quality on the Association between Problematic Mobile Phone Use and Mental Health Symptoms in Chinese College Students

Problematic mobile phone use (PMPU) is a risk factor for both adolescents’ sleep quality and mental health. It is important to examine the potential negative health effects of PMPU exposure. This study aims to evaluate PMPU and its association with mental health in Chinese college students. Furthermore, we investigated how sleep quality influences this association. In 2013, we collected data regarding participants’ PMPU, sleep quality, and mental health (psychopathological symptoms, anxiety, and depressive symptoms) by standardized questionnaires in 4747 college students. Multivariate logistic regression analysis was applied to assess independent effects and interactions of PMPU and sleep quality with mental health. PMPU and poor sleep quality were observed in 28.2% and 9.8% of participants, respectively. Adjusted logistic regression models suggested independent associations of PMPU and sleep quality with mental health (p < 0.001). Further regression analyses suggested a significant interaction between these measures (p < 0.001). The study highlights that poor sleep quality may play a more significant role in increasing the risk of mental health problems in students with PMPU than in those without PMPU.

Quality of life among post-menopausal women due to oxidative stress boosted by dysthymia and anxiety

Background

Menopause is the onset of aging in women. During this process, some women experience physical changes that may impact upon their psychological and social status, also affecting their quality of life. Furthermore, several psychological changes following menopause have been shown to act as pro-oxidant, but the association between the psychological status that modify the quality of life and oxidative stress in postmenopausal women is still unclear. The aim of this study was to determinate the relationship between oxidative stress with psychological disturbances, low self-esteem, depressive mood and anxiety, and quality of life in the postmenopausal women.

Methods

We carried out a cross-sectional study with101 premenopausal and 101 postmenopausal women from Mexico City. As markers of oxidative stress we measured plasma lipoperoxide levels, erythrocyte superoxide dismutase and glutathione peroxidase activities, and total antioxidant status. We calculate a stress score as global oxidative stress status, with cut-off values for each parameter; this score range from 0 to 6, representing the severity of markers modifications. All the women were rated using the Coopersmith Self-Esteem Inventory, the Zung Self-Rating Anxiety and the Zung Self-Rating Depression Scales, and the WHO Quality of Life-brief.

Results

The postmenopausal women with low quality of life in the WHO Quality of Life-brief and their subscales had higher stress score compared with premenopausal women with high quality of life (p < 0.05). We found a positive correlation among lipoperoxide levels and Zung Self-Rating Anxiety and Zung Self-Rating Depression score (r = 0.226 and r = 0.173, respectively, p < 0.05), and a negative correlation with WHO Quality of Life-brief scores (r = −0.266, p < 0.01) in postmenopausal women. Multiple linear regression analysis revealed that average lipoperoxide levels increase by 0.0007 μmol/L for every 1-point increase in the Coopersmith Self-Esteem Inventory and by 0.001 μmol/L for every 1-point decrease in the WHO Quality of Life-brief, after adjusted for pro-oxidant factors. Zung Self-Rating Anxiety and Zung Self-Rating Depression Scales scores also contribute to increase lipoperoxides levels, but not significant.

Conclusion

Our findings suggest that oxidative stress is increased in postmenopausal women with psychological disturbances and low quality of life.

Physical activity in European adolescents and associations with anxiety, depression and well-being

In this cross-sectional study, physical activity, sport participation and associations with well-being, anxiety and depressive symptoms were examined in a large representative sample of European adolescents. A school-based survey was completed by 11,110 adolescents from ten European countries who took part in the SEYLE (Saving and Empowering Young Lives in Europe) study. The questionnaire included items assessing physical activity, sport participation and validated instruments assessing well-being (WHO-5), depressive symptoms (BDI-II) and anxiety (SAS). Multi-level mixed effects linear regression was used to examine associations between physical activity/sport participation and mental health measures. A minority of the sample (17.9 % of boys and 10.7 % of girls; p < 0.0005) reported sufficient activity based on WHO guidelines (60 min + daily). The mean number of days of at least 60 min of moderate-to-vigorous activity in the past 2 weeks was 7.5 ± 4.4 among boys and 5.9 days ± 4.3 among girls. Frequency of activity was positively correlated with well-being and negatively correlated with both anxiety and depressive symptoms, up to a threshold of moderate frequency of activity. In a multi-level mixed effects model more frequent physical activity and participation in sport were both found to independently contribute to greater well-being and lower levels of anxiety and depressive symptoms in both sexes. Increasing activity levels and sports participation among the least active young people should be a target of community and school-based interventions to promote well-being. There does not appear to be an additional benefit to mental health associated with meeting the WHO-recommended levels of activity.

Prevalence and correlates of problematic smartphone use in a large random sample of Chinese undergraduates

BACKGROUND

Smartphones are becoming a daily necessity for most undergraduates in Mainland China. Because the present scenario of problematic smartphone use (PSU) is largely unexplored, in the current study we aimed to estimate the prevalence of PSU and to screen suitable predictors for PSU among Chinese undergraduates in the framework of the stress-coping theory.

METHODS

A sample of 1062 undergraduate smartphone users was recruited by means of the stratified cluster random sampling strategy between April and May 2015. The Problematic Cellular Phone Use Questionnaire was used to identify PSU. We evaluated five candidate risk factors for PSU by using logistic regression analysis while controlling for demographic characteristics and specific features of smartphone use.

RESULTS

The prevalence of PSU among Chinese undergraduates was estimated to be 21.3%. The risk factors for PSU were majoring in the humanities, high monthly income from the family (≥1500 RMB), serious emotional symptoms, high perceived stress, and perfectionism-related factors (high doubts about actions, high parental expectations).

CONCLUSIONS

PSU among undergraduates appears to be ubiquitous and thus constitutes a public health issue in Mainland China. Although further longitudinal studies are required to test whether PSU is a transient phenomenon or a chronic and progressive condition, our study successfully identified socio-demographic and psychological risk factors for PSU. These results, obtained from a random and thus representative sample of undergraduates, opens up new avenues in terms of prevention and regulation policies.

Réactivité physiologique et conscience intéroceptive dans les troubles anxieux pédiatriques : une revue conceptuelle et empirique

L’intéroception, correspondant à la capacité de prendre conscience des sensations corporelles (SC) et réponses physiologiques, est supposée jouer un rôle majeur dans l’émergence de la réponse anxieuse. Chez les adultes, différentes études ont montré une altération des processus intéroceptifs en lien avec l’anxiété, qui s’associe à une sensibilité intéroceptive accrue et, paradoxalement, à une surestimation de l’activité physiologique du corps. Dans la mesure où les modèles cognitifs de l’anxiété insistent sur le rôle de ces processus dans l’étiologie et le maintien de l’anxiété et des troubles anxieux, l’étude de ces processus chez l’enfant souffrant d’anxiété est de premier intérêt. Dans cette revue empirique, nous nous intéresserons à la conscience que l’enfant anxieux a de ses SC et au rôle que celle-ci joue dans la pathogenèse du trouble. Dans la mesure où l’intéroception s’appuie sur la conscience de l’expérience physiologique et notamment des réponses cardiovasculaires, nous commencerons par présenter les données relatives à la réactivité cardiaque dans les troubles anxieux pédiatriques. Après une mise au point conceptuelle, nous synthétiserons ensuite les connaissances actuelles provenant des études ayant investigué les processus intéroceptifs chez l’enfant anxieux. Nous conclurons ce travail par une série de propositions pour les recherches futures.

The role of inflammatory cytokines and ERK1/2 signaling in chronic prostatitis/chronic pelvic pain syndrome with related mental health disorders

Mental health disorders(MHD) in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) have been widely studied. However, the underlying role of inflammatory cytokines and their associated signaling pathways have not been investigated. Here, we report the potential role of cytokines and associated signaling pathways in CP/CPPS patients with MHD and in a CP/CPPS animal model. CP/CPPS patients (n = 810) and control subjects (n = 992) were enrolled in this case-control multicenter study, and serum cytokine levels were measured. Male Sprague-Dawley rats received multiple intracutaneous injections of an immuno-agent along with a pertussis-diphtheria-tetanus triple vaccine for autoimmune CP/CPPS development. The results revealed that, in CP/CPPS patients with significant MHD, elevated IL-1α, IL-1β, IL-4, IL-13, and TNF-α serum levels were observed. The above five cytokines in CP/CPPS rats were significantly elevated in prostate tissue (p < 0.05), and IL-1β levels were elevated in serum and cerebrospinal fluid. In behavioral tests, CP/CPPS rats showed anxiety- and depression-like symptoms, and impaired spatial and associative memory performance (p < 0.05). In the CP/CPPS group, ERK1/2 phosphorylation levels were increased in the amygdala and nucleus accumbens, and decreased in the hippocampus, but not caudate nucleus. Thus, prostate-derived cytokines, especially IL-1β, cross the blood brain barrier and may lead to enhanced ERK1/2 signaling in several brain areas, possibly underlying induction of CP/CPPS-related MHD.

Prevalence and associated risk characteristics of HIV infection based on anal sexual role among men who have sex with men: a multi-city cross-sectional study in Western China

BACKGROUND

The HIV prevalence among men who have sex with men (MSM) in Western China is substantial and increasing at an alarming rate. The current HIV infection prevalence among MSM in Western China and its associated risk characteristics were explored by looking at different anal sexual roles separately.

METHODS

A total 1245 MSM recruited by convenience sampling from multiple sources and areas in the Chongqing and Sichuan region were interviewed using an anonymous self-administered questionnaire with the assistance of investigators and then underwent HIV testing. Multivariate logistic regression was used to identify factors independently associated with HIV infection.

RESULTS

Of the 1235 respondents who reported their sexual roles during anal sex with men, the overall HIV antibody positive rate was 21.21% (262/1235). With regard to the different anal sex roles, HIV-positive rates were significantly higher among men who played the '0.5' role (versatile, equal) and '0' role (only bottom or versatile, but mostly bottom) during anal sex with men than among those who played the '1' role (only top or versatile, but mostly top) (26.41% for '0.5' role, 26.20% for '0' role, and 15.19% for '1' role; Chi-square=22.66, p<0.0001). Statistically significant differences were not found between the '0.5' role and '0' role groups (p > 0.05). The '1' role MSM who had an education level lower than senior high school, a rural household registration, and low self-perceived severity status of AIDS, the '0.5' role MSM who had an education level lower than senior high school and had not undergone HIV testing in the recent 1 year, and the '0' role MSM who were retired or unemployed and had been diagnosed with a sexually transmitted disease by a doctor in the recent 6 months were more likely to be HIV-infected.

CONCLUSIONS

In this study, the HIV prevalence among MSM was alarmingly high. Moreover, the '0.5' and '0' role MSM were found to have a higher risk of infection compared to the '1' role MSM, while respective risk characteristics were not completely the same across the three groups. Along with routine preventive intervention services, more focused and specific interventions are needed to target anal sex role classes separately.

Physiological and psychological factors associated with onset of high-altitude headache in Chinese men upon acute high-altitude exposure at 3700 m

Aim

We aimed to identify clinical characteristics and risk factors associated with onset of high-altitude headache (HAH) after acute exposure at 3700 m.

Method

In two hours, 163 individuals ascended by plane to 3700 m. Demographic information, physiological and psychological measurements, cognitive function, physical work capacity tests and profile of mood states within one week prior to the departure and within 24 hours after arrival were examined.

Results

HAH patients featured significantly higher vertebral artery diastolic velocity (Vd), heart rate (HR) and pulmonary artery diameter. HAH was also associated with a more negative mood state, including scores for tension anxiety, depression, hostility, fatigue and confusion, as well as lower vigor (all p values <0.05). Furthermore, negative emotions were positively related to HAH severity. HAH slightly decreased cognitive functioning. HR, Vd, lack of vigor, confusion and self-reported anxiety (all p values <0.05) were independent risk factors for HAH. We have identified three independent baseline predictors for HAH including internal diameter of the left ventricle (LVD), Athens Insomnia Scale (AIS) and confusion score.

Conclusions

Higher HR, Vd, confusion and self-reported anxiety and insufficient vigor were independent risk factors for HAH. Furthermore, higher baseline LVD, AIS and confusion score are independent predictors of HAH.

Effects of G.H.3. On mental symptoms and health-related quality of life among older adults: results of a three-month follow-Up study in Shanghai, China

OBJECTIVE

To explore the effects of daily use of Gerovital H3 (G.H.3.) tablets on relieving mental symptoms and improving health-related quality of life among Chinese older adults population.

METHODS

In a randomized, placebo-controlled, double-blinded study, totally 100 eligible participants were randomly allocated into the G.H.3. group or the placebo group, administered either G.H.3. or placebo tablets and were followed up for three months. All of the participants were required to report their subjective feelings about quality of life, low mood, and anxiety by filling out Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS) and a 36-item Short-Form Health Survey (SF-36 scale). Physicians were responsible for evaluating the related mental health indications through physical examinations at the baseline and at the end of the intervention period.

RESULTS

Participants were men and women between 50 and 89 years of age, with a median of 62.53 years. Before the intervention, the demographic characteristics and the baseline SF-36 scores, low mood, and anxiety statuses were comparable (p > 0.05). After the 12-week intervention, the scores of role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), mental health (MH) and health transition (HT), mental composite score (MCS) of the G.H.3. group were higher than the placebo group (p < 0.05), There were no significant differences in other domains in SF-36 and PCS between the two groups(p > 0.05), the scores of SDS and SAS in the G.H.3. group were both lower than the placebo group(p < 0.01), the prevalence rates of low moods in the G.H.3. group and the placebo group were 20.8 % and 34.0 % respectively, no significant difference was found (χ (2) =2.127,p = 0.145), while the prevalence rate of clinical anxiety concerns in the G.H.3. group was 2.1 %, which was significantly lower than the placebo group, 22.0 % (χ (2) =9.040,p < 0.001).

CONCLUSIONS

Preliminarily use of G.H.3. shows positive effects in supporting mental health and improving general health and well-being while promoting the recovery of cognitive function among older adults. Most of SF-36 domains including PF, RP, BP, GH, VT, RE, MH, and HT, as well as the overall quality of life in MCS might benefit from taking G.H.3. tablets. Average levels of low moods and anxiety concerns were both reduced and the prevalence rate of clinical anxiety concerns were reduced.

Anxiety rating scales in Parkinson's disease: a critical review updating recent literature

BACKGROUND

Assessing anxiety in Parkinson's disease (PD) has been a recent focus, and a number of studies have extensively investigated the validity of anxiety rating scales in PD. The present review aims to provide an overview of anxiety scales widely used and/or validated in PD, and to highlight recommendations for future research required in this area.

METHODS

A literature search was performed using terms such as Parkinson* disease, psychiatric, depress*, anxiety, assessment, scales, and valid* in PsycInfo, PubMed, and Web of Science databases. Validation studies and reviews focussed on assessment of anxiety in PD were included.

RESULTS

The literature search identified nine anxiety rating scales. The new Parkinson's Anxiety Scale (PAS) showed good psychometric properties. Having a simple design appropriate for older adults and items focussed on cognitive anxiety, the Geriatric Anxiety Inventory (GAI) also appeared promising for use in PD. The Beck Anxiety Inventory (BAI), Hospital Anxiety and Depression Scale, and Hamilton Anxiety Rating Scale (HAM-A) did not demonstrate satisfactory psychometric characteristics when used in PD, while other scales had limited or no evidence of validity or reliability to infer judgments.

CONCLUSIONS

PAS and GAI are can be recommended for use in PD without dementia. Usefulness of these scales to assess anxiety in dementia should be examined in the future. Moreover, the complex symptomatology of anxiety relating to "off" PD medication states were not addressed in these scales. Further research is required to develop an anxiety scale tailored for PD.

Anxiety and Depression are More Prevalent in Primary Angle Closure Glaucoma Than in Primary Open-Angle Glaucoma

PURPOSE

The aim of this study was to assess the prevalence of psychological disturbances and personality traits in primary angle closure glaucoma (PACG) and primary open-angle glaucoma (POAG) patients.

METHODS

A sample of 50 PACG patients, 50 POAG patients, and 50 normal controls were enrolled in this study. All the participants were asked to complete the following questionnaires: Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Eysenck Personality Questionnaire (EPQ), and Defense Style Questionnaire (DSQ). Analysis of variance and t test were used to compare the subscores between the groups.

RESULTS

The scores of SAS and SDS were higher in glaucoma patients than in controls, whereas the PACG group had a higher score for both scales (48.44±9.90; 53.64±9.74) than the POAG group (42.62±9.00, P=0.034; 49.02±11.47, P=0.131) and control group (37.10±6.08, P=0.000; 38.86±6.64, P=0.000). Taking an SAS score of ≥45 and an SDS score of ≥50 as cut-offs, the prevalence of anxiety and depression in the PACG group (66.0%, 56.0%) was significantly higher than in the POAG group (44.0%, P=0.002; 40.0%, P=0.033) and control group (16.0%, P=0.000; 10.0%, P=0.000). The values of psychoticism and neuroticism in EPQ for the PACG and POAG groups were significantly higher than those for controls (P<0.05). In DSQ, PACG and POAG patients adopted immature and neurotic defense styles more often than controls (P<0.05). No significant differences were found between male and female participants in all the questionnaires used (P>0.05).

CONCLUSIONS

Significant differences were found between primary glaucoma patients and normal controls in psychiatric questionnaires, whereas the level of anxiety and depression was found to be significantly higher in PACG patients than in POAG patients and controls.

Psychometric testing of the Chinese version of the Medical Outcomes Study Social Support Survey among people living with HIV/AIDS in China

PURPOSE

The aim of this study was to assess the psychometric properties of the Chinese (Mandarin) version of the Medical Outcomes Study Social Support Survey (MOS-SSS-CM) among people living with HIV/AIDS (PLWHA) in Mainland China.

METHODS

A cross-sectional study was conducted with a convenience sample of 200 Chinese PLWHA. They completed the MOS-SSS-CM along with the Chinese version of the Beck Depression Inventory Revised (BDI-II) scale, the Zung Self-Rating Anxiety Scale (SAS), the Perceived Stress Scale (PSS-10), and the World Health Organization Quality of Life Brief (WHOQOL-BREF) scale.

RESULTS

Internal consistency (Cronbach's α) was 0.97 for the overall MOS-SSS-CM and 0.82-0.91 for the five subscales originally proposed. However, 11 of the 19 items demonstrated unsatisfactory item discriminant validity. An exploratory factor analysis yielded a two-factor solution with tangible and social-emotional dimensions, which demonstrated satisfactory reliability and better discrimination between different subscales than did the original five-factor model. The concurrent validity of the two-factor scale was further confirmed by its significant negative correlations with the BDI-II (r=-0.41, p<0.01); the SAS (r=-0.27, p<0.01); and the PSS-10 (r=-0.30, p<0.01), and significant positive correlation with the WHOQOL-BREF scale (r=0.61, p<0.01).

CONCLUSION

We found a two-factor solution for the MOS-SSS-CM, which demonstrated good reliability and validity when applied to Chinese PLWHA. This was consistent with results from a study of Taiwanese caregivers. Further validation in other populations and disease states is warranted.

Problematic eating behaviors among bariatric surgical candidates: a psychometric investigation and factor analytic approach

Psychological factors (e.g., anxiety, depression) are routinely assessed in bariatric pre-surgical programs, as high levels of psychopathology are consistently related to poor program outcomes (e.g., failure to lose significant weight pre-surgery, weight regain post-surgery). Behavioral factors related to poor program outcomes and ways in which behavioral and psychological factors interact, have received little attention in bariatric research and practice. Potentially problematic behavioral factors are queried by Section H of the Weight and Lifestyle Inventory (WALI-H), in which respondents indicate the relevance of certain eating behaviors to obesity. A factor analytic investigation of the WALI-H serves to improve the way in which this assessment tool is interpreted and used among bariatric surgical candidates, and subsequent moderation analyses serve to demonstrate potential compounding influences of psychopathology on eating behavior factors. Bariatric surgical candidates (n =362) completed several measures of psychopathology and the WALI-H. Item responses from the WALI-H were subjected to principal axis factoring with oblique rotation. Results revealed a three-factor model including: (1) eating in response to negative affect, (2) overeating/desirability of food, and (3) eating in response to positive affect/social cues. All three behavioral factors of the WALI-H were significantly associated with measures of depression and anxiety. Moderation analyses revealed that depression did not moderate the relationship between anxiety and any eating behavior factor. Although single forms of psychopathology are related to eating behaviors, the combination of psychopathology does not appear to influence these problematic behaviors. Recommendations for pre-surgical assessment and treatment of bariatric surgical candidates are discussed.

Psychological well-being of people living with HIV/AIDS under the new epidemic characteristics in China and the risk factors: a population-based study

OBJECTIVES

The HIV/AIDS epidemic in China is growing and the main transmission mode has changed from contaminated blood products to sexual contact. The aim of this study was to evaluate the levels of anxiety (SAS; Zung Self-Rating Anxiety Scale) and depression (CES-D; Center for Epidemiologic Studies Depression Scale) among people living with HIV/AIDS (PLWHA) under the new epidemic characteristics and to examine associated factors.

METHODS

The sample size (N=800) was calculated on the basis of the lowest prevalence of psychological disorders among PLWHA and was enlarged taking into consideration a loss of response. Participants were sampled randomly among all PLWHA registered in Liaoning Province. Questionnaires pertaining to the SAS, CES-D, and related factors were distributed between December 2010 and April 2011; 772 effective responses were received.

RESULTS

The prevalence of anxiety (SAS ≥40) and depression (CES-D ≥16) were 49.0% and 73.1%, respectively. Multivariate logistic regression analysis revealed that SAS was associated with self-rated health, condom use at the last sexual contact, perceived social support, alcohol consumption, and transmission; CES-D was associated with self-rated health, perceived social support, job, and sex.

CONCLUSIONS

PLWHA under the new epidemic characteristics in China suffer from serious psychological problems. To improve their psychological well-being, efforts should be focused on improving perceptions of their health condition and increasing perceived social support.

Regional gray matter volume and anxiety-related traits interact to predict somatic complaints in a non-clinical sample

Somatic complaints can be important features of an individual's expression of anxiety. Anxiety-related traits are also risk factors for somatic symptoms. However, it is not known which neuroanatomical mechanisms may be responsible for this relationship. In this study, our first step was to use voxel-based morphometry (VBM) approaches to investigate the neuroanatomical basis underlying somatic complaints in a large sample of healthy subjects. We found a significant positive correlation between somatic complaints and parahippocampal gyrus (PHG) volume adjacent to the entorhinal cortex. Further analysis revealed that the interaction between PHG volume/entorhinal cortex and neuroticism-anxiety (N-Anx) predicted somatic complaints. Specifically, somatic complaints were associated with higher N-Anx for individuals with increased PHG volume. These findings suggest that increased PHG volume and higher trait anxiety can predict vulnerability to somatic complaints in the general population.

Application of the Geriatric Anxiety Inventory-Chinese Version (GAI-CV) to older people in Beijing communities

BACKGROUND

The Geriatric Anxiety Inventory (GAI) was developed to assess anxiety in older adults. The objectives of this work were as follows: (a) to analyze the psychometric properties of the Chinese version of the GAI (GAI-CV), and (b) to explore the extent of anxiety and related factors in the elderly Chinese residents of Beijing.

METHODS

Participants in this study included 1,047 people (59.4% female) more than 60 years old who were living in the community. They were randomly selected from 15 communities in Beijing. Basic information was collected. Anxiety was measured using the GAI-CV, the Self-Rating Anxiety Scale (SAS), and the Beck Anxiety Inventory (BAI).

RESULTS

The GAI-CV exhibited good internal consistency (Cronbach's α = 0.94) and demonstrated good concurrent validity against the SAS (r = 0.52, p = 0.018) and the BAI (r = 0.560, p = 0.000). Item response theory (IRT) analyses showed that the items of the GAI-CV exhibited high difficulty (0.97-2) and discrimination parameters (1.91-5.33). The items exhibited information parameters greater than 1.25 with the exceptions of items 2, 12, and 18. The GAI-CV scores were significantly associated with gender, age, and chronic disease. However, no significant differences due to marriage or education were found.

CONCLUSIONS

The GAI is a new scale that was specifically designed to measure anxiety in older people. The results of this study suggest that the GAI-CV had good psychometric properties, but some items need to be modified. IRT analyses indicated that the GAI-CV provided good measures of anxiety across the moderately high to very high levels. The GAI-CV may be a useful instrument for further research studies aimed at analyzing high-level anxiety among older adults in China.

A randomized controlled trial of the effects of brief mindfulness meditation on anxiety symptoms and systolic blood pressure in Chinese nursing students

BACKGROUND

Previous studies suggested that mindfulness meditation effectively reduced stress-related anxiety and depression symptoms, but no research has evaluated the efficacy of mindfulness meditation in nurses and nursing students in China.

OBJECTIVES

To evaluate the effects of brief mindfulness meditation on the anxiety and depression symptoms and autonomic nervous system activity in Chinese nursing students.

DESIGN

A randomized controlled trial.

SETTING

A medical university in Guangzhou, China.

PARTICIPANTS

One hundred and five nursing students were randomly approached by email and seventy-two responded. Sixty recruited students were randomized into meditation and control group (n=30 each) after screening and exclusion due to factors known to influence mood ratings and autonomic nervous system measures.

METHODS

The meditation group performed mindfulness meditation 30 min daily for 7 consecutive days. The control group received no intervention except pre-post treatment measurements. The Self-Rating Anxiety Scale and Self-Rating Depression Scale were administered to participants, and heart rate and blood pressure were measured. Pre- and post-treatment data were analyzed using repeated-measures analysis of variance.

RESULTS

Differences between pre- and post-treatment Self-Rating Anxiety Scale scores were significantly larger in the meditation group than in the control group, but no similar effect was observed for Self-Rating Depression Scale scores. Systolic blood pressure was reduced more after the intervention in the meditation group than in the control group, with an average reduction of 2.2 mmHg. A moderate level of anxiety was associated with the maximum meditation effect.

CONCLUSIONS

Brief mindfulness meditation was beneficial for Chinese nursing students in reducing anxiety symptoms and lowering systolic blood pressure. Individuals with moderate anxiety are most likely to benefit from a short-term mindfulness meditation program.

Anxiety correlates with somatic symptoms and sleep status at high altitudes

High altitude exposure results in many physical and psychological discomforts, with anxiety and sleep disturbances being the most common ones. This cross-sectional study was performed to explore the relationship between anxiety, somatic symptoms, and sleep status at high altitude. A sample of 426 young males between 18 and 24 years old ascended from low-level land to 3600 m, where they acclimated for 40 days, before ascending to 4400 m. Questionnaires including the Louise Lake Score (LLS, for diagnosis of acute mountain sickness [AMS]), the Self-rating Anxiety Scale (SAS), the Epworth Sleepiness Scale (ESS), and the Athens Insomnia Scale (AIS) were administered immediately before departure from 3600 m (40th day) and the day after arrival at 4400 m (20 days after the first data collection). Physiological parameters were also measured. We observed that 49 of 426 and 51 of 329 people were diagnosed with anxiety according to SAS at 3600 and 4400 m, respectively. Physical symptoms were more severe in subjects with anxiety, and the severity of anxiety was significantly positively correlated to the severity of insomnia and increased heart rate (HR). Overall, these data indicate that after 40 days acclimatization in 3600 m, anxious persons have more severe somatic symptoms. When ascending to higher altitudes, these individuals are more likely to develop AMS, show more severe symptoms, and are prone to insomnia and more serious daytime sleepiness. Insomnia and elevated HR are indicators of anxiety severity.
