为探讨肝恶性肿瘤患者住院总费用情况,对广西2010年～2012年间肝恶性肿瘤患者的住院费用资料进行统计学分析,比较肝恶性肿瘤患者3年住院总费用的变化情况,并采用多重线性回归分析方法,分析肝恶性肿瘤患者住院总费用的影响因素.结果显示广西肝恶性肿瘤住院患者逐年增多,住院费用逐年增高;住院天数、有无手术、有无合并症、有无院内感染、性别、年龄6个因素是住院总费用的影响因素.我们应加大预防控制肝恶性肿瘤的力度,建立单病种诊疗规范和费用控制标准,推进临床路径管理,以减轻患者的经济负担.     

Posttraumatic Stress Symptoms of Chinese Rural Children and Adolescents Surviving the 2008 Wenchuan Earthquake Assessed Using CRIES

Posttraumatic stress symptoms in Chinese rural children and adolescents were examined after the May 2008 Wenchuan earthquake. Analysis showed that three factors were identified, namely, avoidance, intrusion, and arousal, resembling those in the studies with Western samples. Gender differences in posttraumatic stress symptoms were not significant. Moderate negative correlation coefficients between posttraumatic stress symptom scores and mental health scores were found, indicating that the more severe the posttraumatic stress symptoms, the worse the person's mental health.     

Effects of telephone support on exercise capacity and quality of life in patients with chronic obstructive pulmonary disease: a meta-analysis

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.     

Effects of psychological interventions for patients with osteoarthritis: a systematic review and meta-analysis

The aim of this study was to determine the effects of psychological interventions (e.g. cognitive restructuring, relaxation) on physiological and psychological health in osteoarthritis patients. A systematic literature search was done using PubMed, Embase, PsycINFO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database through November 2016. Studies were included if they used a randomized controlled trial designed to explore the effects of psychological interventions in osteoarthritis patients. Two independent authors assessed the methodological quality of the trials using criteria outlined by Jadad et al. Meta-analysis was done with the Revman5.0. Twelve randomized controlled trials, including 1307 osteoarthritis patients, met the study inclusion criteria. Meta-analysis showed that psychological interventions could reduce the levels of pain [standard mean difference (SMD) ?0.28, 95% CI ?0.48, ?0.08, P-value 0.005)] and fatigue (SMD ?0.18, 95% CI ?0.34, ?0.01, P-value 0.04). In addition, psychological interventions significantly improved osteoarthritis patients’ self-efficacy (SMD 0.58, 95% CI 0.40, 0.75, P-value 0.00) and pain coping (MD 1.64, 95% CI 0.03, 3.25, P-value 0.05). Although the effects on physical function, anxiety, depression, psychological disability were in the expected direction, they were not statistically significant. In conclusion, the role of psychological interventions in the management of osteoarthritis remains equivocal. Some encouraging results were seen with regard to pain, pain coping, self-efficacy, and fatigue. We believe that more methodologically rigorous large-scale randomized controlled trials are necessary to answer this study question.     

Nostalgia and Temporal Life Satisfaction

Recent research has shown that nostalgia, an apparently past-oriented emotion, may render the present self more positive and promote a brighter outlook on the future. The current study examined whether experimentally induced nostalgia would impact the levels of and associations among past, present, and future life satisfaction. Among 250 university students (86 males and 164 females, aged 16–26 years), nostalgia was manipulated through the recollection of nostalgic (vs. ordinary) events. In support of our hypotheses, the results showed that nostalgic experiences not only led to a larger contrast between past life satisfaction versus present and future life satisfaction, but also weaker associations between past and future life satisfaction and between present and future life satisfaction. Overall, the findings suggest that nostalgic experiences can render more distinct judgements on temporal life satisfaction.     

父母心理控制与对立违抗障碍儿童抑郁和攻击行为的关系:父子依恋和母子依恋的中介效应

采用父母心理控制、亲子依恋、抑郁量表对从北京市、山东省和云南省14所小学筛选出来的246名对立违抗障碍(Oppositional Defiant Disorder,ODD)儿童进行施测,并由被试的班主任填写儿童攻击行为量表,考察父、母心理控制对ODD儿童抑郁和攻击行为的影响,以及父子依恋和母子依恋在其中的中介作用。结果发现:(1)ODD儿童中男生人数更多,且男孩的抑郁和攻击行为更严重;(2)父亲对男孩的心理控制更强,而母亲在对男孩和女孩的心理控制上没有显著差异;(3)父、母心理控制与ODD儿童的父子依恋、母子依恋和抑郁均呈显著相关,但只有父亲心理控制与ODD儿童的攻击行为显著相关;(4)父子依恋在父母心理控制和ODD儿童抑郁之间没有起到显著的中介作用,母子依恋在母亲心理控制和ODD儿童抑郁之间有显著的中介作用。父子依恋和母子依恋在父、母心理控制和ODD儿童攻击行为之间均没有起到显著的中介作用。     

我国贫困大学生心理健康变迁的横断历史研究:1998~2015

为探讨自1999年高校国家助学贷款政策出台以来,我国贫困大学生心理健康状况的变迁,本研究对106篇1998至2015年间采用SCL-90量表的研究进行了横断历史元分析,考察了贫困大学生心理健康状况随年代的变化趋势。结果表明：（1）SCL-90量表中9个因子的分数均值均与年代呈负相关,年代对各因子变异的解释在4%至16%之间;1998年到2015年这18年来,各因子均值平均下降范围（效果量d）在0.24至0.55个标准差之间,其中强迫、抑郁和精神病3个因子均值变化尤为明显。这表明贫困大学生整体心理健康的状况在缓慢提升。（2）与中部地区相比,东部和西部地区贫困大学生心理健康水平18年来提高更明显。（3）虽然不同性别贫困大学生各因子历年变化差异并不明显,但女生抑郁和精神病两方面改善略快。此外,普通元分析结果表明总体上贫困男大学生比女大学生心理健康状况要好。     

乡镇小学生的数学焦虑与数学成绩:数学自我效能感和数学元认知的链式中介作用

采用儿童数学焦虑量表、小学生数学学习自我效能感量表和小学生数学元认知问卷,对508名乡镇中、高年级小学生进行测量,并运用结构方程模型探讨数学焦虑影响数学成绩的内在作用机制。结果发现：（1）数学焦虑显著负向预测数学自我效能感、数学元认知和数学成绩,数学自我效能感显著正向预测数学元认知和数学成绩,数学元认知显著正向预测数学成绩;（2）在数学焦虑对数学成绩的预测中,数学自我效能感和数学元认知均发挥了部分中介作用;（3）数学自我效能感和数学元认知在数学焦虑和数学成绩之间起链式多重中介的作用。因此,数学焦虑除了直接作用于小学生的数学成绩,还可通过数学自我效能感或数学元认知间接影响数学成绩,而且可通过数学自我效能感进而通过数学元认知间接影响数学成绩。文章讨论了上述发现的理论及教育实践含义。     

Score-Based Tests of Differential Item Functioning via Pairwise Maximum Likelihood Estimation

Measurement invariance is a fundamental assumption in item response theory models, where the relationship between a latent construct (ability) and observed item responses is of interest. Violation of this assumption would render the scale misinterpreted or cause systematic bias against certain groups of persons. While a number of methods have been proposed to detect measurement invariance violations, they typically require advance definition of problematic item parameters and respondent grouping information. However, these pieces of information are typically unknown in practice. As an alternative, this paper focuses on a family of recently proposed tests based on stochastic processes of casewise derivatives of the likelihood function (i.e., scores). These score-based tests only require estimation of the null model (when measurement invariance is assumed to hold), and they have been previously applied in factor-analytic, continuous data contexts as well as in models of the Rasch family. In this paper, we aim to extend these tests to two-parameter item response models, with strong emphasis on pairwise maximum likelihood. The tests’ theoretical background and implementation are detailed, and the tests’ abilities to identify problematic item parameters are studied via simulation. An empirical example illustrating the tests’ use in practice is also provided.     

Testing an integrated model of the work–family interface in Chinese employees: A longitudinal study

The purpose of this study was to examine an integrated model of the work–family interface (WFI) linking work–family demands (workload and family conflict), resources (supervisory support and family support) and role satisfaction in a Chinese context. The four‐factor structure of WFI comprises direction of influence (work to family vs family to work) and types of effect (work–family conflict vs work–family enrichment). A longitudinal design was used to collect data from 409 Chinese employees at three time points, separating measures of antecedents (T1), WFI (T2) and outcomes (T3) in time. The results based on structural equation modelling (SEM) reveal that: (1) the direction and types of effect were two underlying dimensions of the WFI, supporting the four‐factor structure; (2) demands were more strongly related to conflict, while resources were more strongly related to enrichment; (3) work–family conflict and enrichment were related to role satisfaction, regardless of the direction of influence.
