Anton HA, Miller WC, Townson AF. Measuring fatigue in persons with spinal cord injury.
Objective
To evaluate the psychometric properties of the Fatigue Severity Scale (FSS) in persons with spinal cord injury (SCI).Design
A 2-week methodologic study was conducted to assess the internal consistency, reliability, and construct validity of the FSS.Setting
A tertiary spinal cord rehabilitation facility.Participants
Forty-eight community-living subjects at least 1 year post-SCI with American Spinal Injury Association (ASIA) grade A or B SCI and no medical conditions causing fatigue. The sample was predominantly male (n=31 [65%]) with tetraplegia (n=26 [54%]) and ASIA grade A injuries (n=30 [63%]). The average duration since injury was 14.9 years.Interventions
Not applicable.Main Outcome Measures
The ASIA Impairment Scale, the FSS, a visual analog scale for fatigue (VAS-F), the vitality scale of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the Center for Epidemiologic Studies Depression Scale (CES-D).Results
Mean FSS score ± standard deviation at baseline was 4.4±1.4, with 54% (n=26) scoring greater than 4. The internal consistency of the FSS was excellent (Cronbach α=.89). Two-week test-retest reliability was adequate (intraclass correlation coefficient, .84; 95% confidence interval, .74-.90). The magnitude of the relationship was as hypothesized for the VAS-F (r=.67) and CES-D (r=.58) and lower than hypothesized for the vitality subscore (r=−.48) of the SF-36.Conclusions
The FSS has acceptable reliability with regard to internal consistency, test-retest reliability, and validity in persons with motor complete SCI. 相似文献2.

Moriello C, Mayo NE, Feldman L, Carli F. Validating the six-minute walk test as a measure of recovery after elective colon resection surgery.
Objective
To provide evidence for construct and longitudinal validity of the six-minute walk test (6MWT) as a measure of postsurgical recovery.Design
Data from a randomized clinical trial.Setting
A major teaching hospital in a Canadian urban city.Participants
Patients (N=63) undergoing elective colon resection.Interventions
Not applicable.Main Outcome Measures
Functional walking capacity was measured using the 6MWT at before surgery and at 3 and 6 weeks after surgery.Results
At 3 weeks, 26 (41%) patients recovered to baseline or greater on the 6MWT distance, and 37 (59%) were at baseline or better by 6 weeks postdischarge. At all time points, the 6MWT distance correlated with age, the American Society of Anesthesiologists (ASA) score of surgical risk, albumin, the physical function subscale of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), and the physical component summary score of the SF-36. Baseline 6MWT distance correlated with postoperative 6MWT recovery, and baseline SF-36 and ASA were associated with postoperative recovery. Patients with intraoperative complications had a clinically relevant lower 6MWT than those without complications at all time points.Conclusions
This study provides evidence for construct validity and sensitivity to change for the 6MWT as a measure of surgical recovery. 相似文献4.
Gross DP, Battié MC, Asante AK. The Patient-Specific Functional Scale: validity in workers' compensation claimants.
Objective
To examine the construct and predictive validity of the Patient-Specific Functional Scale (PSFS) in workers' compensation claimants.Design
Prospective cohort study with 1-year follow-up.Setting
A workers' compensation rehabilitation facility.Participants
Subjects included 294 claimants with a variety of musculoskeletal disorders. The sample was predominantly male (70%), with a mean age of 44 years. Subjects completed a battery of measures at baseline including the PSFS, the Pain Disability Index (PDI), and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36).Interventions
Not applicable.Main Outcome Measures
Outcomes for determining predictive validity included administrative indicators of timely return to work and recovery during the 1-year follow-up. Analysis included Pearson correlation and multivariable Cox and logistic regression.Results
At baseline, the PSFS correlated moderately (r range, 0.3−0.5) with other indicators of functional limitation (PDI, SF-36 role−physical subscale) but negligibly with the SF-36 mental health and role−emotional subscales. The PSFS was associated with timely recovery (adjusted hazard ratio, 1.16; 95% confidence interval, 1.07-1.27) with increasing functional limitation related to delayed recovery.Conclusions
Results provide construct and predictive validity evidence for the PSFS as an indicator of functional limitation in workers' compensation claimants. 相似文献5.

Background
Preventing tobacco consumption and promoting cessation among health professionals are of great significance as their habits can influence their patients’ attitudes. Knowledge of the prevalence and characteristics of tobacco use in a specific population is important for the design of efficient strategies for preventing people from acquiring the habit and persuading them to stop. Self-administered questionnaires are a very common method for determining tobacco use, but assessment is needed of their validity for specific groups, such as occasional smokers or students of health sciences.Objectives
The aim of this study was to determine the sensitivity and specificity of a self-administered questionnaire for determining tobacco use among a population of young female students of health sciences. As a gold standard, we used a measure of the concentration of cotinine in saliva with different cut-off points. We also analysed the influence on sensitivity and specificity of the questionnaire of nicotine dependence and exposure to secondary smoke.Design
This is an internal validity study (sensitivity and specificity) of a self-administered questionnaire.Settings
The study was carried out in the School of Health Sciences of the University of León, at its centres in León and Ponferrada.Participants
Data were collected on 432 of a total of 480 women aged under 25 who were studying Health Sciences at the University of León in 2007.Methods
The self-administered questionnaire included data concerning demography, education, tobacco habits and exposure to environmental smoke. Saliva cotinine concentration was determined with an EIA kit.Results
The questionnaire used showed high values of sensitivity and specificity (85.3% and 95.3%) and a very good correlation (Kappa = 81.0%) with cotinine values of 10 ng/ml or higher. Discrepancies in the test results for those who declared themselves to be smokers only occurred in women with a low nicotine dependency. Among those who did not declare themselves smokers, those exposed to second-hand smoke were 7 times more frequently classified erroneously as smokers than those who had not been exposed.Conclusion
The self-administered questionnaire used showed a very good internal validity and a good correlation with cotinine levels of 10 ng/mg, and therefore seems to be a good instrument for measuring tobacco use in this population. The availability of information on passive smoking and nicotine dependence is essential for the correct interpretation of the discrepancies. 相似文献6.
Lee CE, Browell LM, Jones DL. Measuring health in patients with cervical and lumbosacral spinal disorders: is the 12-Item Short-Form Health Survey a valid alternative for the 36-Item Short-Form Health Survey?
Objectives
To determine the convergent validity of the 12-Item Short-Form Health Survey, version 2 (SF-12v2), with 36-Item Short-Form Health Survey, version 2 (SF-36v2), in patients with spinal disorders, and to determine other key factors that might further explain the variances between the 2 surveys.Design
Cross-sectional study.Setting
Orthopedic ambulatory care.Participants
Eligible participants (N=98; 24 with cervical, 74 with lumbosacral disorders) who were aged 18 years and older, scheduled to undergo spinal surgery, and completed the SF-36v2.Interventions
Not applicable.Main Outcome Measures
SF-36v2 and SF-12v2 (extracted from the SF-36v2).Results
The 2 summary scores, physical and mental component scores (r range, .88-.97), and most of the scale scores (r range, .81-.99) correlated strongly between the SF-12v2 and SF-36v2, except for the general health score (cervical group, r=.69; lumbosacral group, r=.76). Stepwise linear regression analyses showed the SF-12v2 general health scores (cervical: β=.61, P<.001; lumbosacral: β=.68, P<.001) and the level of comorbidities (cervical: β=−.37, P=.014; lumbosacral: β=−.18, P=.039) were significant predictors of the SF-36v2 general health score in both groups, whereas age (β=.32, P<.001) and smoking history (β=−.22, P=.005) were additional predictors in the lumbosacral group.Conclusions
SF-12v2 is a practical and valid alternative for the SF-36v2 in measuring health of patients with cervical or lumbosacral spinal disorders. The validity of the SF-12v2 general health score interpretation is further improved when the level of comorbidities, age, and smoking history are taken into consideration. 相似文献7.

Brooks D, Davis L, Vujovic-Zotovic N, Boulias C, Ismail F, Richardson D, Goldstein RS. Sleep-disordered breathing in patients enrolled in an inpatient stroke rehabilitation program.
Objective
To report the prevalence of sleep-disordered breathing in an inpatient stroke rehabilitation unit and to explore correlations with functional status and health-related quality of life.Design
Cross-sectional study.Setting
Rehabilitation center.Participants
Consecutive patients (N=45; mean age, 67±12y) (28 men) enrolled in inpatient rehabilitation after ischemic (84%) or hemorrhagic stroke (16%).Interventions
Not applicable.Main Outcome Measures
Overnight respiratory polysomnography was performed on all subjects. Interviewer-administered scales of sleepiness (Epworth Sleepiness Scale) and functional status (FIM, Barthel Index) were completed. Health-related quality of life was assessed by using a general questionnaire (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]).Results
Of the 45 subjects tested, only 4 (9%) had an apnea-hypopnea index of less than 10 per hour. The mean apnea-hypopnea index was 32.2 (19.4) per hour; most events were obstructive. There was no relationship between the respiratory index and the components of SF-36 (P values>.2).Conclusions
There was a dramatically high prevalence of respiratory events in patients after stroke enrolled in an inpatient stroke rehabilitation unit. The awareness of this will influence patient evaluation and management. 相似文献8.

Background
The Edinburgh Postnatal Depression Scale (EPDS) has been validated in many countries, but not in Mainland China.Objectives
This study investigated the reliability and validity of the Mainland Chinese version of the EPDS.Design
A three-stage design was used for this study. Stage I consisted of a multi-stepped process of forward and backward translation, using a panel of six experts to test content validity. Stage II established the psychometric properties of the EPDS by examining the convergent, discriminant and construct validity, internal consistency and stability of the scale. Stage III established its sensitivity, specificity and the optimal cutoff score of the EPDS according the DSM-IV-TR criteria using the Structured Clinical Interview.Setting
Three regional public hospitals in Chengdu.Participants
A convenience sample was composed of 312 and 451 pregnant women at 28-36 weeks’ gestation.Method
Translation and back-translation of the original English instrument and content validation by an expert panel. Receiver operating characteristic (ROC) analysis was carried out to evaluate the global functioning of the scale. The Beck Depression Inventory (BDI), Dyadic Adjustment Scale (DAS) and standard SF-12 Health Survey (SF-12) were used to investigate the convergent, discriminant and construct validity. The Cronbach's alpha reliability coefficient, split-half reliability and test-retest reliability were used to examine the internal consistency and stability of the scale.Results
The translation process was rigorously conducted to ensure that equivalence was established. Content validity was confirmed by a satisfactory level of agreement with a content validity index (CVI) of 0.93. The area under curve (AUC) was 85.6% and the logistic estimate for the threshold score was 9.5 (sensitivity, 80.0%; specificity, 83.03%) for clinical depression. Convergent and construct validity was supported and discriminant validity suggested that the EPDS successfully discriminated among the non-depressed, mildly and clinically depressed groups. The split-half reliability of the EPDS was 0.76, Cronbach's alpha was 0.79 and test-retest reliability was 0.85.Conclusions
Based on the results of this psychometric testing, the Mainland Chinese version of the EPDS is considered ready for use in the routine screening of pregnant women. It is hoped that with this type of cross-cultural information, the universality of the constructs of the instrument can be reliably demonstrated. 相似文献9.

Noonan VK, Kopec JA, Zhang H, Dvorak MF. Impact of associated conditions resulting from spinal cord injury on health status and quality of life in people with traumatic central cord syndrome.
Objective
To determine the effect of associated spinal cord injury (SCI) conditions on the health status and quality of life (QOL) in people with traumatic central cord syndrome.Design
Cross-sectional design.Setting
Community-based.Participants
Subjects (N=70) with traumatic central cord syndrome who were a minimum of 2 years postinjury.Interventions
Not applicable.Main Outcome Measures
Presence of associated SCI conditions (neuropathic pain, spasticity, bowel, bladder, and/or sexual dysfunction, decreased motor function); health status (36-Item Short-Form Health Survey [SF-36], symptom satisfaction); and QOL.Results
The SF-36 physical component score (PCS) was lower in subjects who reported problems with bowel, bladder, and/or sexual function (−6.9; 95% confidence interval [CI], −11.6 to −2.2). The PCS was decreased in subjects with a lower motor score and this relationship was negatively affected by spasticity and being less educated. The SF-36 mental component score was negatively affected by neuropathic pain and a lower motor score. Neuropathic pain and a lower motor score were both associated with subjects being dissatisfied with their symptoms. Subjects who had a higher motor score were more likely to have a higher QOL (odds ratio, 1.7; 95% CI, 1.1 to 2.7).Conclusions
The associated SCI conditions bowel, bladder, and/or sexual dysfunction, neuropathic pain, decreased motor function, and spasticity negatively affect the health status of persons with traumatic central cord syndrome. Diminished motor recovery was the only associated SCI condition to impact QOL. By developing a conceptual model and adjusting for confounders, an estimate for each associated SCI condition's effect on patient outcomes was obtained. Our results indicate the importance of treating or ameliorating associated SCI conditions in order to maximize physical and mental functioning. 相似文献10.

Latham NK, Mehta V, Nguyen AM, Jette AM, Olarsch S, Papanicolaou D, Chandler J. Performance-based or self-report measures of physical function: which should be used in clinical trials of hip fracture patients?
Objectives
To assess the validity, sensitivity to change, and responsiveness of 3 self-report and 4 performance-based measures of physical function: activity measure for postacute care (AM-PAC) Physical Mobility and Personal Care scales, the Medical Outcomes Study 36-Item Short Form Health Survey Physical Function scale (SF-36 PF), the Physical Functional Performance test (PFP-10), the Short Physical Performance Battery (SPPB), a 4-meter gait speed, and the six-minute walk test (6MWT).Design
A prospective observational study of patients after a hip fracture. Assessments were performed at baseline and 12 weeks postenrollment.Setting
Inpatient and outpatient rehabilitation facilities in Norway, the United Kingdom, Sweden, Israel, Germany, the United States, Denmark, and Spain.Participants
A sample of study participants (N=108) who had a hip fracture.Interventions
Not applicable.Main Outcome Measures
Assessments of validity (known-groups, concurrent, construct, and predictive), sensitivity to change (effect size, standardized response mean [SRM], SE of measure, minimal detectable change (MDC), and responsiveness (optimal operating cut-points and area under the curve) between baseline and 12-week follow-up.Results
All physical function measures achieved comparably acceptable levels of validity. Odds ratios in predicting patient Global Assessment of Improvement at 12 weeks were as follows: AM-PAC Physical Mobility scale, 5.3; AM-PAC Personal Care scale, 3.6; SF-36 PF, 4.3; SPPB, 2.0; PFP-10, 2.5; gait speed, 1.9; and 6MWT, 2.4. Effect sizes and SRM exceeded 1 SD for all 7 measures. Percent of patients who exceeded the MDC90 at week 12 were as follows: AM-PAC Physical Mobility scale, 90%; AM-PAC Personal Care scale, 74%; SF-36 PF, 66%; SPPB, 36%; PFP-10, 75%; gait speed, 69%; and 6MWT, 75%. When evaluating responsiveness using the area under receiver operating curves for each measure, all measures had acceptable responsiveness, and no pattern emerged of superior responsiveness depending on the type of measure used.Conclusions
Findings reveal that the validity, sensitivity, and responsiveness of self-report measures of physical function are comparable to performance-based measures in a sample of patients followed after fracturing a hip. From a psychometric perspective, either type of functional measure would be suitable for use in clinical trials where improvement in function is an endpoint of interest. The selection of the most appropriate type of functional measure as the primary endpoint for a clinical trial will depend on other factors, such as the measure's feasibility or the strength of the association between the hypothesized mechanism of action of the study intervention and a functional outcome measure. 相似文献11.

Objective
To determine whether Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) items show differential item functioning among healthy adults with various types of functional limitations as compared with a healthy sample with no identified limitations.Design
Survey responses were analyzed by using partial correlations.Setting
General community.Participants
Participants (N=206) included (1) adults with spinal cord injury (SCI), (2) adults who were deaf or hard of hearing, (3) adults who were legally blind, (4) adults with psychiatric or emotional conditions, and (5) adults with no reported functional limitations. Participants were screened to ensure the absence of substantial health problems.Interventions
Not applicable.Main Outcome Measure
SF-36.Results
Partial correlations showed a significant negative correlation, indicating differential item functioning (ie, apparent bias) for people with SCI on all 10 SF-36 Physical Functioning items. For people who were blind, 5 items showed a significant negative correlation. Two items had significant negative correlations for the deaf/hard-of-hearing group. One item showed significant negative performance for people with mental health conditions.Conclusions
Our data indicated a possibility for measurement bias caused by the blending of health and function concepts in the SF-36. 相似文献12.

Gill TM, Gahbauer EA, Van Ness PH. Psychometric properties of a scale to assess the severity of bathing disability.
Objective
To develop and evaluate the psychometric properties of a new bathing disability scale.Design
Reliability and validity study.Setting
General community.Participants
Two subsets of community-living older persons, selected from an ongoing longitudinal study, who had some degree of bathing disability or were at increased risk for bathing disability, as determined during a comprehensive assessment at 36 (N=199) and 54 (N=213) months, respectively.Interventions
Not applicable.Main Outcome Measures
The bathing disability scale was administered at 36, 54, and 72 months, and changes in scores were assessed between 36 and 54 months and 54 and 72 months, respectively, for the 2 subsets of participants. Convergent construct validity was evaluated by comparisons with changes in activity of daily living (ADL) disability, mobility disability, and the Short Physical Performance Battery (SPPB). Discriminative construct validity was determined by comparisons according to age and physical frailty. Responsiveness was evaluated by comparisons between participants who had and had not been hospitalized and, subsequently, by plotting correlations according to the timing of these hospitalizations.Results
The test-retest reliability was high, with an intraclass correlation coefficient=0.76 (95% confidence interval=0.59−0.94). The internal consistency reliability was excellent with Cronbach α=0.91−0.97. Changes in scores on the bathing disability scale were positively correlated with changes in scores in ADL and mobility disability and inversely correlated with changes in scores on the SPPB. A greater decline in scores was observed among the oldest old and those who were physically frail, but these differences did not consistently achieve statistical significance. The scale was responsive to the occurrence and/or timing of intervening hospitalizations.Conclusions
The bathing disability scale is reliable, valid, and responsive and may be suitable for use in clinical trials to evaluate the effectiveness of interventions to enhance independent bathing. 相似文献13.
Objective
To analyze the relative validity of the 17-item Manchester Foot Pain and Disability Index (MFPDI) using graded response item response theory analysis (G-IRT).Design
The design of the study involved a survey instrument validation.Participants/Patients
A total of 682 respondents with a history of foot pain in the last month.Methods
Factor analysis and G-IRT were used to analyze the dimensionality and relative validity of each scale item.Results
Exploratory factor analysis yielded a two-factor solution. G-IRT resulted in the removal of one of the original 17 items from the MFPDI. Analyses revealed that six of the nine foot and ankle function items of the MFPDI demonstrated excellent discrimination. For the seven pain and appearance items, only one item demonstrated excellent discrimination, the remaining demonstrated moderate discrimination.Conclusion
G-IRT was successful in outlining selected items representative of disability and pain and appearance. By reducing the MFPDI to 16 items, the Modified MFPDI is multidimensional and is associated with the underlying construct of activity related foot and ankle disability and pain and appearance. By reducing the MFPDI to 16 items, a clinician can be confident that the outcome instrument accurately represents the latent construct of disability and pain and appearance. 相似文献14.

Objective
Our goal was to create a parsimonious combination of the Modified Somatic Perception Questionnaire (MSPQ) and the Pain Beliefs Screening Instrument (PBSI) through factorial structural analysis and to investigate the associations of the new scale (if unique) to disability, health condition, and quality of life report in patients with neck and low back pain scheduled for spine fusion surgery.Methods
Factor analysis was used to refine all items within the 2 scales to 4 distinct factors: (1) somatic complaints of the head/neck, (2) somatic complaints of the gastrointestinal symptom, (3) pain beliefs and fear, and (4) self perception of serious problems. Each factor was assessed for concurrent validity with other well-established tools including the Deyo comorbidity index, the Short Form (SF)-36 mental and physical component subscales, and the Oswestry and Neck Disability Indices (ODI/NDI).Results
The PBSI was fairly to moderately correlated with assessment tools of quality of life (SF-36) and disability assessment (ODI/NDI). Some of the items in the factor 1 from the MSPQ were slightly associated with the Deyo comorbidity index but not with the ODI/NDI.Conclusions
The items from the MSPQ failed to associate with measures of quality of life and disability and thus may provide only marginal value when assessing the multidimensional aspects associated with neck and low back pain. The PBSI has moderate correlation with disability assessments. Neither tool was found to strongly correlate with disability measures or with SF-36 scales (mental and physical component subscales). Additional tools may be needed to further identify the dimensions associated with chronic pain patients. 相似文献15.

Background
Profound knowledge of pressure ulcers is important to enable good prevention. Validity and reliability of instruments assessing pressure ulcer knowledge are limited evaluated in previous research.Aims and objectives
To develop a valid and reliable instrument to assess knowledge of pressure ulcer prevention.Design
Prospective psychometric instrument validation study.Methods
An extensive literature review was performed to develop an instrument to assess knowledge of pressure ulcer prevention. Face and content validity were evaluated in a double Delphi procedure by an expert panel of nine trustees of the European Pressure Ulcer Advisory Panel (EPUAP) who each have extensive experience in pressure ulcer care and research (PhD level). A convenience sample of 608 nurses and nursing students from Belgium and The Netherlands participated to evaluate validity of the multiple-choice test items (item difficulty, discriminating index, quality of the response alternatives), construct validity, internal consistency, and stability of the instrument. The data were collected between February and May 2008.Results
A 26-item instrument was developed, reflecting 6 themes expressing the most relevant aspects of pressure ulcer prevention. The content validity was excellent (CVI = 0.78-1.00). Group scores of nurses with a (theoretically expected) high level of expertise were found to be statistically significantly higher than those of participants with (theoretically expected) less expertise (P < 0.001). The item difficulty index of the questions ranged from 0.27 to 0.87, while values for item discrimination ranged from 0.29 to 0.65. The quality of the response alternatives was found to be good. The overall internal consistency reliability (Cronbach's α) was 0.77. The 1-week test-retest intraclass correlation coefficient (stability) was 0.88.Conclusion
The instrument demonstrated acceptable psychometric properties and can be applied in both research and practice for evaluating knowledge about pressure ulcer prevention. 相似文献16.

Context
Quality of life (QOL) for patients is now a worldwide concern, but there are few specific instruments developed by modular approach to measure outcomes in chronic diseases.Objectives
This study aimed to develop and validate the System of Quality of Life Instruments for Chronic Diseases—General Module (QLICD-GM).Methods
Based on the World Health Organization’s definition of QOL and programmed decision procedures, the QLICD-GM was developed using focus group discussions, pilot tests of 201 cases, and field tests of 620 cases representing seven different chronic diseases. The number of items in the final version was reduced to 30 from a 73-item pool, and the psychometric properties of the scale were evaluated by indicators, such as validity and reliability coefficients, standardized response mean, and statistical methods of correlational analysis, t-tests, and structural equation modeling.Results
Correlational and structural equation model analyses confirmed good construct validity with root mean square error of approximation of 0.0606, nonnormed fit index of 0.941, and comparative fit index of 0.947. Test-retest reliability coefficients for all domains and facets were higher than 0.70, with a range of 0.71-0.92, and the internal consistency alphas for most domains and facets were higher than 0.65 (ranging from 0.52 to 0.89). All domains and overall scores of the QLICD-GM had a statistically significant change after treatment, with moderate effect size.Conclusion
The QLICD-GM has good validity, reliability, and better responsiveness compared with the SF-36® Health Survey and can be used as the general module for chronic diseases. 相似文献18.

Tang WK, Lu JY, Chen YK, Mok VC, Ungvari GS, Wong KS. Is fatigue associated with short-term health-related quality of life in stroke?
Objective
To evaluate the relation between poststroke fatigue and short-term health-related quality of life (HRQOL) in Chinese patients with first or recurrent stroke.Design
Cross-sectional survey.Setting
Acute stroke unit of a general hospital.Participants
A total of 458 patients with acute ischemic stroke admitted to the acute stroke unit of a university-affiliated regional hospital in Hong Kong.Interventions
Not applicable.Main Outcome Measures
HRQOL was assessed with the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) at 3 months after the subjects' index stroke. Fatigue was evaluated by using the Fatigue Severity Scale (FSS). The correlation between the FSS and SF-36 scores was examined and adjusted for potential confounders, including age, sex, marital status, previous stroke, social support, global cognitive functions, neurologic deficits, and depressive symptoms.Results
Univariate analysis revealed that fatigue was a significant correlate of all SF-36 domain scores. The magnitude of correlation was highest for the vitality domain (r=−.605, Bonferroni corrected P<.05) and lowest for the physical functioning domain (r=−.202, Bonferroni corrected P<.05). Canonic correlation analysis indicated that FSS was strongly related to the HRQOL with a loading of −.678. Increasing fatigue was associated with a lower HRQOL. The association between FSS and HRQOL remained significant in the subsequent multivariate regression analysis, having adjusted for possible confounders.Conclusions
These findings suggest that fatigue has an impact on short-term HRQOL in Chinese stroke patients. The early identification and treatment of fatigue may improve HRQOL of stroke patients. 相似文献19.

Background
The Metabolic Syndrome (MS) is a combination of risk factors related to increased risk of cardiovascular disease. Psychosocial factors and stress have been suggested to be important determinants.Aim
To analyse how psychosocial factors, perceived stress and health related quality of life are related to MS, and assess if observed associations are dependent of life-style.Methods
A cross-sectional study of a random sample of 502 men and 505 women aged 45-69, from southeast Sweden, including fasting blood samples, blood pressure, anthropometrics, self-reported data of life-style, psychosocial status and health related quality of life (SF-36). Linear regression models were adjusted for age and, in a second step, also for life-style.Results
Men and women with MS reported lower levels of physical activity, lower scores on physical and social dimensions of SF-36, and women with MS reported stronger effect of social change compared to those without MS (p < 0.05), but we found no differences for mental health or perceived stress. The major part of observed associations was lost after adjustment for effects of life-style.Conclusion
Our data speak against a direct effect of social stress on MS via psychological strain but suggest an indirect pathway via a sedentary life-style. 相似文献20.
