SF-36量表用于国人脊髓型颈椎病的信度分析及其与神经功能的相关性研究

目的:评估SF-36量表用于国人脊髓型颈椎病(cervical spondylotic myelopathy,CSM)患者健康相关生活质量(quality of life,QOL)的信度,并验证术后疗效评价中,生活质量评价与神经功能评估的一致性。方法:本研究前瞻性收集了接受手术治疗的脊髓型颈椎病患者142例,男84例,女58例,年龄60.0±10.9岁。所有患者均接受手术治疗。分别于术前、术后3个月、术后1年和术后2年以上末次随访时分别使用改良日本骨科协会评分法(modified Japanese Orthopaedic Association,mJOA)评分和健康状况调查简表(SF-36量表)进行神经功能和生活质量评估,并与正常人群的常模进行对比。使用克隆巴赫系数(Cronbachα)分析SF-36量表八个维度的信度,并进一步分析在术后不同随访时间节点SF-36各维度与神经功能评价的相关性。根据患者各项评分的变化趋势,分析患者的康复峰值时间。结果:术前CSM患者SF-36量表8个维度中,除“精神健康”维度外,其余7各维度较健康成年人常模均存在显著功能缺陷。SF-36量表各维度的Cronbachα介于0.73~0.85之间(Cronbachα:生理功能=0.85、生理职能=0.83、躯体疼痛=0.80、整体健康=0.81、活力=0.81、社会功能=0.79、情感职能=0.73、精神健康=0.75)。术后3个月时,mJOA评分的改善仅与患者SF-36量表中生理功能和躯体疼痛两个维度得分有显著相关性(相关系数R:生理功能=0.32,躯体疼痛=0.20;P<0.05);术后1年时,mJOA评分的改善与SF-36量表中生理功能、整体健康、社会功能和情感职能四个维度有显著相关性(相关系数R:生理功能=0.39,整体健康=0.24,社会功能=0.22,情感职能=0.19;P<0.05);在术后2年以上末次随访时,mJOA评分的改善与SF-36量表中生理功能、活力和情感职能三个维度显著相关(相关系数R:生理功能=0.38,活力=0.20,情感职能=0.20;P<0.05)。SF-36量表的生理总评分和心理总评分分别在17.7个月和18.9个月达到峰值。结论:SF-36量表各维度的信度较高,是一项可靠的评估CSM患者健康相关生活质量的方法。在术后不同随访期的疗效评估中,SF-36量表各维度与神经功能改善评估的一致性不尽相同:在术后恢复早期,mJOA评分的改善与SF-36量表中的生理相关维度显著相关;随着术后恢复期延长,mJOA评分的改善则与生理、心理相关维度均显著相关。     

Reliability and validity for the measurement of moral disengagement in pharmacists

BackgroundSocial cognitive theory describes a process in which behavior can be disengaged from moral self control through eight different mechanisms. These mechanisms were used for the development of a new scale for measuring moral disengagement (Moral Disengagement Inventory, or MDI) in pharmacists.ObjectivesThe objectives of this study were to assess the reliability and validation of a scale to measure pharmacists' moral disengagement toward patients who exhibit behaviors directly or indirectly leading to their disease condition, such as an asthmatic patient who smokes or a non-compliant asthmatic patient.MethodsA self-administered survey called the Moral Disengagement Instrument (MDI) was developed for this study. Once the MDI was designed, the items were evaluated for content validity, readability and face validity. The reliability of the developed measures was assessed. The convergent and discriminant validity of the moral disengagement constructs were tested using confirmatory factor analysis.ResultsThe reliability coefficient for the MDI for the asthmatic smoker was 0.814 and reliability coefficient for the MDI for the non-compliant asthmatic patient was 0.782. Evidence supporting validity of the MDI was provided in a confirmatory factor analysis.ConclusionsThe Moral Disengagement Instrument (MDI), developed as a tool for measuring pharmacists' disengagement beliefs for a smoker asthmatic patient and a non-compliant asthmatic patient, was found to be reliable and valid.     

Reliability and Validity of Digital Imaging as a Measure of Schoolchildren's Fruit and Vegetable Consumption

BackgroundAs more and more interventions aim to increase schoolchildren's fruit and vegetable (FV) consumption, less resource-intensive yet valid alternatives to weighed plate waste (WPW) are needed for assessing dietary intake.ObjectivesWe aimed to test the reliability and validity of digital imaging (DI) and digital imaging with observation (DI+O) in assessing children's FV consumption during school lunch.DesignFV consumption (in grams) was assessed on lunch trays from third- to fifth-grade children over eight visits (31 to 68 trays collected per visit) to compare WPW with DI and DI+O.SettingTwo elementary schools (327 and 631 students enrolled, respectively).Main outcome measuresInterobserver reliability of DI. Validity of DI and DI+O compared against WPW.Statistical analysesReliability was assessed by percent agreement and intraclass correlation coefficients (ICCs). Validity was assessed by Pearson correlations, paired t tests, and Bland-Altman plots.ResultsReliability was acceptable for DI; percent agreement was 96% and the ICC was 0.92. FV consumption assessments by DI and WPW (n=159) were highly correlated (r=0.96; P<0.001). Mean FV consumption using DI (96.7 g) was within 1.0 g of WPW and not significantly different from WPW (P=0.56), and Bland-Altman limits of agreement for individual-tray FV consumption were –32.9 to 31.3 g. FV consumption assessments by DI+O and WPW were highly correlated (r=0.98; P<0.001). Mean FV consumption using DI+O (99.3 g) was within 1.0 g of WPW and not significantly different from WPW (P=0.38), and limits of agreement for individual-tray FV consumption were –25.0 to 26.8 g.ConclusionsDI was reliable for assessing children's FV consumption during school lunch. DI and DI+O were valid for assessing mean consumption but less precise for estimating individual-tray consumption. Valid estimations of mean FV consumption were achieved using DI without cafeteria observations, thereby reducing labor and time. Thus, DI is especially promising for assessing children's mean FV consumption during school lunch.     

Evaluation of Web-Based,Self-Administered,Graphical Food Frequency Questionnaire

Computer-administered food frequency questionnaires (FFQs) can address limitations inherent in paper questionnaires by allowing very complex skip patterns, portion size estimation based on food pictures, and real-time error checking. We evaluated a web-based FFQ, the Graphical Food Frequency System (GraFFS). Participants completed the GraFFS, six telephone-administered 24-hour dietary recalls over the next 12 weeks, followed by a second GraFFS. Participants were 40 men and 34 women, aged 18 to 69 years, living in the Columbus, OH, area. Intakes of energy, macronutrients, and 17 micronutrients/food components were estimated from the GraFFS and the mean of all recalls. Bias (second GraFFS minus recalls) was −9%, −5%, +4%, and −4% for energy and percentages of energy from fat, carbohydrate, and protein, respectively. De-attenuated, energy-adjusted correlations (intermethod reliability) between the recalls and the second GraFFS for fat, carbohydrate, protein, and alcohol were 0.82, 0.79, 0.67, and 0.90, respectively; for micronutrients/food components the median was 0.61 and ranged from 0.40 for zinc to 0.92 for beta carotene. The correlations between the two administrations of the GraFFS (test–retest reliability) for fat, carbohydrate, protein, and alcohol were 0.60, 0.63, 0.73, and 0.87, respectively; among micronutrients/food components the median was 0.67 and ranged from 0.49 for vitamin B-12 to 0.82 for fiber. The measurement characteristics of the GraFFS were at least as good as those reported for most paper FFQs, and its high intermethod reliability suggests that further development of computer-administered FFQs is warranted.

Validity and Reliability of the Modified Manchester Health Questionnaire in Assessing Patients With Fecal Incontinence

PURPOSE To date, no measures of fecal incontinence severity or its impact on quality of life have been validated for telephone interview. This study was designed to 1) compare responses of a self-administered and a telephone-administered Fecal Incontinence Severity Index; 2) compare a self-administered Fecal Incontinence Quality of Life Scale to the Manchester Health Questionnaire after modifying the latter for telephone administration and American English (Modified Manchester Health Questionnaire); 3) assess test-retest reliability of the telephone-administered Modified Manchester Health Questionnaire; and 4) assess the internal consistency of the Modified Manchester Health Questionnaire subscales.METHODS Consecutive, English-speaking, nonpregnant females known to have fecal incontinence were invited to participate. Two validated paper questionnaires accompanied the letter informing them of the study: Fecal Incontinence Severity Index and Fecal Incontinence Quality of Life Scale. Consenting patients were contacted for the initial telephone administration of the Modified Manchester Health Questionnaire, and patients who agreed to continue the study were contacted for a repeat telephone administration of the Modified Manchester Health Questionnaire two to four weeks after completing the first interview.RESULTS Fifty-one females were invited to participate in the study; however, 13 declined or were ineligible. Thirty females, aged 49.3 ± 10.3 years, returned self-administered questionnaires and completed the first telephone interview, and 21 completed a second telephone interview after an average interval of 23 days. The telephone-administered Fecal Incontinence Severity Index scores were significantly lower than those yielded by the self-administered Fecal Incontinence Severity Index, (6.19 vs. 9.85; P < 0.001), but the telephone and written administrations were significantly correlated (r = 0.5; P < 0.02). Correlations between the Modified Manchester Health Questionnaire quality of life subscales and the paper Fecal Incontinence Quality of Life subscales ranged from 0.6 to 0.9 (median, r = 0.81). The correlation between the total score for the Fecal Incontinence Quality of Life and the total score for the Modified Manchester Health Questionnaire quality of life scales was 0.93 (P < 0.001). Test-retest reliability for the eight Modified Manchester Health Questionnaire subscales ranged from 0.55 to 0.98 (median, r = 0.83), and test-retest reliability for the two telephone administrations of the Fecal Incontinence Severity Index was r = 0.75. Cronbachs alpha for the eight Modified Manchester Health Questionnaire subscales ranged from 0.79 to 0.92 (median, alpha = 0.85).CONCLUSIONS Telephone-administered versions of the Modified Manchester Health Questionnaire showed good-to-excellent validity, internal consistency, and test-retest reliability. The telephone-administered Fecal Incontinence Severity Index yielded lower severity scores than the written Fecal Incontinence Severity Index; however, the difference (3.66 units) was not clinically significant.Supported by Pelvic Floor Disorders Network.Supported by NICHD grants U10 HD41249, U10 HD41268, U10 HD41248, U10 HD41250, U10 HD41261, U10 HD41263, U10 HD41269, U10 HD41267.Presented at the American Urogynecologic Society, Hollywood, Florida, September 11 to 13, 2003.Reprints are not available.

Reliability and validity of the German short version of the Activities specific Balance Confidence (ABC-D6) scale in older adults

The Activities specific Balance Confidence (ABC) is a questionnaire which was developed to assess falls-associated self-efficacy. The aim of this study was to evaluate reliability and validity of the German abbreviated 6-item version of the ABC scores in community-dwelling older people. The study sample included 384 subjects (age 71.1 ± 9.7). In order to determine the psychometric properties, reliability and validity were assessed through administration of the German adaptation of the ABC-D16 to participants twice, 10 days apart, and comparison of the ABC-D16 and the ABC-D6 with functional measures of balance and mobility (one-leg stance; 10 m walk; TUG; Fullerton Advanced Balance Scale (FAB)), physical activity (Physical Activity Scale for the Elderly (PASE)), physical fitness (30 s arm curl, 30 s chair stand, 6 min walk), cognition (Trail-Making-Test (TMT)), falls status, and quality of life (SF36). Factor analyses suggested a 1-factor solution for the ABC-D6 scale (explained variance 79.8%). Internal consistency (.95) and test-retest reliability (.98) for the ABC-D6 scores were excellent. Scores on the ABC-D6 were significantly lower than on the ABC-D16, but ABC-D16 and ABC-D6 scores were highly correlated (.94). There was an increasing difference in the ABC-scores between men and women with increasing age. Fallers reported lower balance confidence than non-fallers. The ABC-D6 score significantly correlated with functional measures of balance and mobility, physical activity, physical fitness, cognition, and quality of life (−.698 < r < .720). It was found that the ABC-D6 is a reliable and valid instrument to asses falls-associated self-efficacy and may be used in future research projects and clinical trials.
