Psychometric Properties of the Cervical Smear Belief Inventory for Chinese Women

This study examines the reliability and validity of the scores of Cervical Smear Belief Inventory (CSBI) among Chinese women in Taiwan. Women who were nonadherent to cervical screening guidelines were recruited (N = 424). Reliabilities showed good internal consistency for the perceived Pros, Cons, and Susceptibility scales (α ranged from .78 to .87). Factor analysis showed good construct validity of the scores of CSBI that revealed concordant patterns with existing social and behavioral theories, except that the Norms scale was loaded with the Pros scale. Moreover, two items in the Cons scale appeared to be “cultural belief toward virginity.” Item-discrimination analysis showed that all items in the CSBI successfully discriminated women with favorable cervical smear beliefs from those with unfavorable beliefs (p < .001). In summary, many psychometric properties of the CSBI showed that the scores of the inventory were reliable and valid to assess belief toward cervical smear among Chinese women.     

Normal variation and abnormality: an empirical study of the liability distributions underlying depression and delinquency

BACKGROUND: Scale scores in studies of emotional and behavioural problems often possess highly skewed distributions. The long upper tails of these distributions place a small proportion of the population at some distance from the main body of the distribution. This invites an interpretation of their forming an abnormal group, one that may be qualitatively distinct. METHODS: Item-response models were fitted to data on parent and self-rated depression and delinquency from four large samples of children or adolescents. RESULTS: We found that underlying liability distributions show very little or no evidence of non-normality. CONCLUSIONS: The results suggest that (i) the skewed nature of the scale scores may be largely measurement artefacts, (ii) the distributions provide no evidence of a qualitatively distinct process generating abnormality as compared to normal variation and (iii) for characterising the whole distribution, including normality and abnormality, the selection of items in typical current assessments of emotional and behavioural problems is not optimal.     

Considerations for Measuring Functioning of the Elderly: IRM Dimensionality and Scaling Analysis

Modern measurement methods were applied in this study to examine the properties of a measure of functioning of the elderly. Measures of functioning form an essential element in health services and outcomes research. Several implications for scale development and improved score precision are presented in this case study. This study examined the structure of responses to the Older Americans Resources and Services (OARS) Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales using item response model (IRM) analysis methods. The analysis illustrates the extension of IRM dimensionality and item analysis to health scales in general. Attention is given to the underlying theory and appropriate interpretation of these methods for health measurement.Data were taken from 1364 elderly Canadians participating in the caregiver component of the Canadian Study of Health and Aging (CSHA). The fit of a two-parameter logistic IRM was compared with a one-parameter (Rasch) model for these data. The dimensionality of responses to the scale was evaluated with an approximate ² test of residuals after fitting an IRM based on non-linear factor analysis. Results confirm that ADL and IADL item sets differ in the degree of disability they measure and are well represented as separate dimensions using a two-parameter IRM. Implications are drawn concerning the adequacy of the OARS disability measure for health surveys, while more general conclusions cover the precision of IRM based optimal scoring for functional disability measures.     

单项筛选在病案终末质量控制中的作用

目的检查病历终末质量，探讨单项筛选的重要性，提高病历书写质量。方法参照国家、省、市有关病历书写规定，采用单项筛选法，对所有出院病案进行逐份检查。结果在71，319份病案中，发现9285份有不同程度的缺陷，其中乙级病历650份，丙级病历120份，病案完整率为86．98％。结论单项筛选法可以保证病案的完整性，减少由于病历资料的缺陷而造成的医疗纠纷。

穿支蒂皮瓣修复臀骶部软组织缺损

目的探讨应用穿支蒂皮瓣修复臀骶部软组织缺损的手术方法及临床效果。方法1998年以来临床应用8例,其中男5例,女3例。年龄15～79岁。根据缺损部位及大小设计以臀部、骶旁或腰动脉的皮穿支为血管蒂的轴型穿支蒂皮瓣移位修复臀骶部褥疮、溃疡及外伤性软组织缺损创面。切取皮瓣达6cm×5cm～19cm×11cm,穿支血管口径1.3～2.1mm,游离穿支血管蒂长度为2.5～4.5cm。结果皮瓣全部成活,伤口期愈合。随访6～24个月,皮瓣质地优良,外形满意,溃疡无复发。结论穿支蒂皮瓣设计灵活,切取方便,血供可靠,不损伤臀部肌肉,供区无需植皮,是修复臀骶部软组织缺损创面的理想方法。     

三痹汤治疗膝骨性关节炎

目的:观察三痹汤治疗膝骨性关节炎(knee osteoarthritis,KOA)的临床疗效。方法:120例KOA患者随机平均分为治疗组和对照组。治疗组给予三痹汤,对照组给予硫酸氨基葡萄糖胶囊。治疗后,比较两组患者临床疗效,临床症状疗效,视觉模拟评分(visual analogue scale,VAS),西安大略和麦克马斯特大学骨关节炎指数(Western Ontario and McMaster university of orthopedic index,WOMAC)评分,健康调查简表(the MOS item short from health survey,SF-36)评分及不良反应。结果:治疗组有效率为86.7%(52/60),对照组为60.0%(36/60),两组有效率比较,差异有统计学意义(P<0.05)。治疗后,两组临床症状评分比较,治疗组无效例数显著少于对照组,差异均有统计学意义(P<0.05)。治疗后,两组患者VAS、WOMAC评分均低于治疗前,治疗组治疗后低于同期对照组,差异均有统计学意义(P<0.05)。治疗后,两组患者SF-36评分均高于治疗前,治疗组治疗后高于同期对照组,差异均有统计学意义(P<0.05)。治疗组不良反应率为5.00%,对照组为16.67%,两组不良反应率比较,差异有统计学意义(P<0.05)。结论:三痹汤治疗KOA临床疗效显著,可显著改善患者临床症状,降低VAS、WOMAC评分,提高SF-36评分,且无明显不良反应。     

泻肝安神方改善广泛性焦虑症患者生活质量的观察

目的观察泻肝安神方改善广泛性焦虑症（GAD）肝郁化火证患者中文版健康调查简易量表（SF-36）生活质量评分情况及SF-36各维度与焦虑的相关性分析。方法将130例GAD患者随机分为治疗组和对照组,治疗组100倒,对照组30例,分剐口服泻肝安神方和帕罗西汀治疗,疗程均为6周。以SF-36、汉密顿焦虑量表（HAMA）对两组GAD肝郁化火证患者治疗前后生活质量水平及焦虑程度进行评价。结果两组在治疗前后SF-36各条目间比较均无统计学意义（P〉0．05）,但两组在治疗6周后与本组治疗前SF-36各维度比较有统计学意义（P〈0．01）。两组在治疗前后SF-36各维度中除生理机能外,其余各维度值与HAMA总分及因子分呈显著负相关（P〈0．05）。结论泻肝安神方在改善GAD肝郁化火证患者的生活质量水平方面与帕罗西汀相当,且患者的焦虑情绪对其生活质量影响较大,即患者的焦虑情绪越严重其生活质量水平越低。
