The study aims to investigate the quality of life (QOL) and the psychological situation in Chinese patients with rosacea. A total of 196 healthy controls and 201 rosacea patients were involved in the final analysis. The general information, the Dermatology Life Quality Index (DLQI) and the Hospital Anxiety and Depression Scale (HADS) were collected. Significantly higher DLQI, anxiety and depression score were observed in the rosacea group compared to the control group (p < .01). Total DLQI score of patients was positively related with anxiety (r = .526, p < .001) and depression scores (r = .399, p < .001) in HADS. Rosacea had significant psychological impact on Chinese patients and had substantial influence on their QOL. Physicians should address the psychosocial needs of rosacea patients as much as its physical symptoms. 相似文献

The aim of this meta-analysis was to evaluate the effects of disease education or pulmonary rehabilitation programs assisted with telephone support on physical capacity and quality of life (QOL) in chronic obstructive pulmonary disease (COPD) patients. A systematic search of PubMed, Embase, Web of Science and The Cochrane Library was conducted until May 2017. Randomized controlled trials (RCTs) examining the effects of telephone-assisted intervention versus a control group on exercise tolerance and QOL in patients with COPD were included. Two independent authors assessed the methodological quality of the trials using the Cochrane risk of bias tool. A meta-analysis was conducted with the Revman5.3 to quantify the effects of telephone-assisted interventions on walking capacity and QOL. In total, 10 studies involving 1037 participants were included. Due to the effect of telephone-assisted interventions, statistically significant results were found on Saint-George’s Respiratory Questionnaire (SGRQ) symptom scores [standard mean difference (SMD) ?.18, 95% confidence interval (CI) ?.33, ?.03, p-value .02)], SGRQ impact scores [SMD ?.35, 95% CI ?.60, ?.10, p-value .006)], SGRQ activity scores [SMD ?.30, 95% CI ?.45, ?.15, p-value < .0001)], SGRQ total score [SMD ?.36, 95% CI ?.51, ?.21, p-value < .00001)]. The effects on 6-min walk test (6MWT) and all Chronic Respiratory Questionnaire (CRQ) subscales were not significant (p > .05) based on the insufficient evidence. In conclusion, the role of telephone-assisted interventions in the management of COPD remains equivocal. Some encouraging results were seen with regard to SGRQ symptom, SGRQ impact, SGRQ activity and SGRQ total score. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question. 相似文献

To confirm the relationship between pro‐social behaviour and increased physical functioning revealed by previous researchers in Western samples, we conducted four experiments with 378 Chinese undergraduates. The participants' strength to hold, to grip and to lift, as well as their vitality (walking speed), were measured after thinking of acts of kindness. The results showed that recalling pro‐social behaviour (helping others or spending money on others) that had occurred in the past or imagining pro‐social behaviour happening in the future imbued people with more physical strength and vitality. In three experiments, pro‐social behaviour boosted the positive mood of the actors, but the effect was only significant in one experiment, suggesting that the hidden gift may include increased happiness, but that enhanced physical functioning cannot be accounted for by differences in emotions. These results add to the evidence that the function of pro‐social behaviour in promoting physical functioning may be culturally universal. 相似文献

To understand how individuals’ senses of competence are cultivated, scholars have primarily focused on situational factors such as job autonomy and supervisor support. Against this backdrop, we propose that individuals can work as active agents and enhance their sense of competence by initiating actions that aim to master the environment. We adopt the behavioral concordance model and propose that people higher in proactive personality are more likely to engage in proactive behavior that elevates their senses of competence over time. We further propose that such behavioral concordance contributes to boosting a sense of competence is more prominent among those with higher proactive personality. Our predictions are supported by data from 172 employees and their direct supervisors in China, after controlling for the effect of job autonomy and supervisor support for autonomy. Specifically, only those higher in proactive personality engaged in more proactive behavior and increased their sense of competence over time. This study highlights both a self-initiated and a behavioral perspective on understanding the development of a sense of competence. 相似文献

This article investigates how test-takers change their strategies to handle increased test difficulty. An adult sample reported their test-taking strategies immediately after completing the tasks in a reading test. Data were analyzed using structural equation modeling specifying a measurement-invariant, ability-moderated, latent transition analysis in Mplus (Muthén & Asparouhov, 2011). It was found that almost half of the test-takers (47%) changed their strategies when encountering increased task-difficulty. The changes were characterized by augmenting comprehending-meaning strategies with score-maximizing and test-wiseness strategies. Moreover, test-takers' ability was the driving influence that facilitated and/or buffered the changes. The test outcomes, when reviewed in light of adjusted test-taking strategies, demonstrated a form of process-based validity evidence. 相似文献

Attention toward social entrepreneurship has increased worldwide, particularly within younger generations. Based on the identified model of social entrepreneurial intentions, this study proposed a multiple mediation framework to examine the mediating role of entrepreneurial creativity for university students. It also compared the differences between Taiwanese (N = 311) and Hong Kong students (N = 311). Through a survey using both online and offline channels, the results of Study 1 confirmed the factor structures of the 3 scales, involving 5 antecedents of social entrepreneurial intention (i.e., empathy, moral obligation, self-efficacy, perceived social support, and prior experience with social problems), 2 factors of entrepreneurial creativity (i.e., originality and usefulness), and 2 factors of social entrepreneurial intention (i.e. conviction and preparation). The results of Study 2 supported the proposed multiple mediation model across regions. Prior experience with social problems, perceived social support, and originality were identified as the 3 most influential factors affecting the social entrepreneurial intentions of university students. The major differences between Taiwan and Hong Kong involved prior experience, empathy, self-efficacy, perceived social support, and usefulness. 相似文献

UNDERSTANDING PARENTING STRESS AND CHILDREN'S BEHAVIOR PROBLEMS AMONG HOMELESS,SUBSTANCE‐ABUSING MOTHERS 下载免费PDF全文
This article tested a model of parenting stress as a mediator between maternal depressive symptoms, emotion regulation, and child behavior problems using a sample of homeless, substance‐abusing mothers. Participants were 119 homeless mothers (ages 18–24 years) and their young children (ages 0–6 years). Mothers responded to questions about their depressive symptoms, emotion regulation, parenting stress, and child behavior problems. A path analysis showed that maternal depressive symptoms were positively associated with child behavior problems through increased parenting stress whereas maternal cognitive reappraisal was negatively associated with child behavior problems through decreased parenting stress. Moreover, maternal expressive suppression was negatively related to child externalizing problems. Findings support the parenting stress theory and highlight maternal parenting stress as a mechanism associated with homeless children's mental health risk. This study has significant implications for understanding the parenting processes underlying child's resilience in the context of homelessness and maternal substance use. 相似文献

Health-related quality of life (HRQoL) is a well-established measure of health and general well-being. Socioeconomic status (SES) can affect HRQoL. We sought to determine whether there were differences in HRQoL between low versus higher area-SES flat communities in Singapore. Residents in two integrated public housing precincts comprising of rental-flat blocks (low area-SES neighborhood) and neighboring owner-occupied blocks (higher area-SES neighborhood) were asked to rate their self-perceived HRQoL using the EuroQol Group five dimensions (EQ-5D) instrument. The EQ-5D assesses HRQoL in five domains (mobility, self-care, usual activities, anxiety/mood and pain) and with a global visual analogue scale (EQ-VAS). We evaluated differences in HRQoL between the rental and owner-occupied neighborhoods, and factors associated with anxiety/depression in the rental-flat neighborhood using multivariate logistic regression. The participation rate was 89.1% (634/711). In the owner-occupied neighborhood, 56.7% (216/381) were in full health, compared with 54.2% (137/253) in the rental-flat population (OR = 0.90, 95%CI = 0.66–1.24, p = 0.568). Across the five domains, staying in a rental-flat neighborhood was independently associated with anxiety/depression (adjusted odds ratio [aOR] = 1.79, 95%CI = 1.10–2.92, p = 0.019). In the rental-flat population, having anxiety/depression was independently associated with minority ethnicity, problems with self –care, pain/discomfort, difficulty with healthcare costs, and not being on subsidized primary care (p < 0.05). There was no significant difference on the EQ-VAS between the two neighborhoods (p = 0.627). Staying in a low area-SES neighborhood was associated with more mental health problems. In the rental-flat population, self-reported anxiety/depression was associated with minority ethnicity, physical health problems, and financial disadvantage in healthcare. 相似文献

Humans exhibit a remarkable ability to discriminate variations in object volume based on natural haptic perception. The discrimination thresholds for the haptic volume perception of the whole hand are well known, but the discrimination thresholds for haptic volume perception of fingers and phalanges are still unknown. In the present study, two psychophysical experiments were performed to investigate haptic volume perception in various fingers and phalanges. The configurations of both experiments were completely dependent on haptic volume perception from the fingers and phalanges. The participants were asked to blindly discriminate the volume variation of regular solid objects in a random order by using the distal phalanx, medial phalanx, and proximal phalanx of their index finger, middle finger, ring finger, and little finger. The discrimination threshold of haptic volume perception gradually decreases from the little finger to the index finger as well as from the proximal phalanx to the distal phalanx. Overall, both the shape of the target and the part of the finger in contact with the target significantly influence the precision of haptic perception of volume. This substantial data set provides detailed and compelling perspectives on the haptic system, including for discrimination of the spatial size of objects and for performing more general perceptual processes. 相似文献

The authors' aim was to find the features of balance, proprioception, and gross motor development of Chinese children 3–6 years old and their correlations, provide theoretical support for promoting children's motor development, and enrich the world theoretical system of motor development. This study used a Tekscan foot pressure measurement instrument (Tekscan, Inc., Boston, MA), walking on a balance beam, Xsens 3-dimensional positional measuring system (Xsens Technologies, Enschede, the Netherlands), and Test of Gross Motor Development-2 to assess static balance, dynamic balance, knee proprioception, and levels of gross motor development (GMD) of 3- to 6-year-old children (n = 60) in Beijing. The results are as follows: children had significant age differences in static balance, dynamic balance, proprioception, and levels of GMD; children had significant gender differences in static balance, proprioception, and levels of GMD; children's static balance, dynamic balance, and proprioception had a very significant positive correlation with GMD (p < .01), but no significant correlation with body mass index. 相似文献
