Reliability and validity of a German asthma quality of life questionnaire.

The Asthma Quality of Life Questionnaire (University of Sydney [AQLQ-Sydney]) is a self-administered questionnaire that has been developed in Australia and validated in different languages in Australia, the USA and Spain. We developed a German translation of this questionnaire by applying a sequential forward and backward translation approach. The objective of this study was to validate a German translation of the AQLQ-Sydney questionnaire in an outpatient population of asthmatic patients in Switzerland. Outpatients were assessed for a diagnosis of asthma and those who consented were selected for the validation study. All patients had spirometry, methacholine challenge testing, fractional exhaled nitric oxide recorded and answered the German AQLQ-Sydney. A subgroup of 17 patients answered the questionnaire for a second time after receiving asthma treatment with combined steroids and bronchodilators for two months. Test-retest-reliability was tested in 12 stable asthmatic patients without treatment modification. Of 90 patients assessed, 57 were diagnosed with asthma and participated in the validation study. The total score did not significantly correlate with any of the objective measures of severity of asthma. However, the "Breathlessness" subscale score correlated weakly with PD20 methacholine. Internal consistency was high with Cronbach's alpha of 0.97 for the total score and 0.91-0.97 for the subscale scores. Test-retest reliability was also high for the total score and the subscale scores. The questionnaire detected a significant improvement in total quality of life score and "Breathlessness" and "Mood" subscale scores after a period of combined treatment with inhaled steroids and long acting bronchodilators. The German translation of the AQLQ-Sydney had a good internal consistency and test-retest-reliability in stable asthmatic patients. It shows responsiveness to treatment. Some correlations with objective markers were detected.

Questionnaire versus direct technical measurements in assessing postures and movements of the head, upper back, arms and hands.

OBJECTIVES: This study compares questionnaire-assessed exposure data on work postures and movements with direct technical measurements. METHODS: Inclinometers and goniometers were used to make full workday measurements of 41 office workers and 41 cleaners, stratified for such factors as musculoskeletal complaints. The subjects answered a questionnaire on work postures of the head, back, and upper arms and repeated movements of the arms and hands (3-point scales). The questionnaire had been developed on the basis of a previously validated one. For assessing worktasks and their durations, the subjects kept a 2-week worktask diary. Job exposure was individually calculated by time-weighting the task exposure measurements according to the diary. RESULTS: The agreement between the self-assessed and measured postures and movements was low (kappa = 0.06 for the mean within the occupational groups and kappa = 0.27 for the whole group). Cleaners had a higher measured workload than office workers giving the same questionnaire response. Moreover, the subjects with neck-shoulder complaints rated their exposure to movements as higher than those without complaints but with the same measured mechanical exposure. In addition, these subjects also showed a general tendency to rate their postural exposure as higher. The women rated their exposure higher than the men did. CONCLUSIONS: The questionnaire-assessed exposure data had low validity. For the various response categories the measured exposure depended on occupation. Furthermore, there was a differential misclassification due to musculoskeletal complaints and gender. Thus it seems difficult to construct valid questionnaires on mechanical exposure for establishing generic exposure-response relations in epidemiologic studies, especially cross-sectional ones. Direct technical measurements may be preferable.

The Copenhagen Psychosocial Questionnaire--a tool for the assessment and improvement of the psychosocial work environment.

OBJECTIVES: The aim of this article is to present the Copenhagen Psychosocial Questionnaire (COPSOQ), a questionnaire developed in three different lengths for assessing psychosocial factors at work, stress, and the well-being of employees and some personality factors. The purpose of the COPSOQ concept is to improve and facilitate research, as well as practical interventions at workplaces. METHODS: The development of the questionnaire was based on a survey of a representative sample of 1858 Danish employees aged 20-59 years. The response rate was 62%; 49% were women. Altogether 145 questions from some international and Danish questionnaires and 20 self-developed questions were tested with factor analyses, analyses of internal reliability, and analyses of response patterns. RESULTS: The analyses resulted in a long research version of the questionnaire with 141 questions and 30 dimensions, a medium-length version for work environment professionals with 95 questions and 26 dimensions, and a short version for workplaces with 44 questions and 8 dimensions. Most of the scales have good reliability, and there seems to be very little overlap between the scales. A novel feature of the COPSOQ is the development of five different scales on demands at work. CONCLUSIONS: The COPSOQ concept is a valid and reliable tool for workplace surveys, analytic research, interventions, and international comparisons. The questionnaire seems to be comprehensive and to include most of the relevant dimensions according to several important theories on psychosocial factors at work. The three versions facilitate communication between researchers, work environment professionals, and workplaces.

[The quality of life after radical prostatectomy measured by general health questionnaire and visual analogue scales].

OBJECTIVES: The impact of radical prostatectomy on the quality of life (QOL) of patients were evaluated. MATERIALS AND METHODS: A total of 22 patients who underwent radical prostatectomy for clinically localized prostate cancer entered this study. Patients were asked to complete a questionnaire containing the general health questionnaire (GHQ) and a series of questions evaluating voiding function, incontinence and sexual dysfunction before and after the operation. In addition, the visual analogue scaled (VAS) questionnaire containing incontinence and sexual dysfunction was applied. RESULTS: No significant differences in GHQ were found between pre- and post operative status, but disease-targeted QOL such as sexual function was affected after the radical prostatectomy. In the points of incontinence and sexual dysfunction, VAS questionnaire significantly correlated with those of categorical questionnaires. CONCLUSIONS: There results suggest that GHQ is not affected, but disease-targeted QOL in some categories of sexual function is affected by radical prostatectomy, and that VAS questionnaires are not only useful for assessing the disease-targeted QOL but also easy to quantify QOL of the patients.

Self-report questionnaire scores in rheumatoid arthritis compared with traditional physical, radiographic, and laboratory measures.

STUDY OBJECTIVE: To assess whether scores on a simple self-report questionnaire to depict the clinical status of patients with rheumatoid arthritis are correlated with traditional measures of physical, radiographic, laboratory, functional, and global status. DESIGN: The self-report questionnaire was administered at the same time the following variables were assessed: American Rheumatism Association functional class, joint count, hand radiograph, erythrocyte sedimentation rate, rheumatoid factor titer, walking time, grip strength, button test, and global self-assessment. SETTING: University rheumatology clinic, the rheumatology clinic of a Veterans Administration hospital, and a private rheumatology practice. PATIENTS: The study included 259 patients who met the criteria of the American Rheumatism Association for a diagnosis of definite or classic rheumatoid arthritis. INTERVENTIONS: Standard rheumatologic care for patients with rheumatoid arthritis. MEASUREMENTS AND MAIN RESULTS: Self-report questionnaire scores were significantly correlated with the joint count, radiographic score, erythrocyte sedimentation rate, grip strength, button test, walking time, American Rheumatism Association functional class, and global self-assessment. Patients were categorized into five questionnaire score categories of 1.00, indicating no dysfunction, and 1.01 to 1.50, 1.51 to 2.00, 2.01 to 3.00, and 3.01 to 4.00, indicating progressive dysfunction. In these five categories, more than ten involved joints were seen in 11%, 37%, 67%, 79%, and 100% of patients, respectively, and erythrocyte sedimentation rates greater than 20 mm/h in 29%, 49%, 64%, 74%, and 85% of patients, respectively. Similar results were seen for other physical and radiographic measures. The questionnaire score was as effective in explaining other measures of clinical status as was any other available measure. CONCLUSIONS: A simple self-report questionnaire provides information similar to many traditional measures in rheumatoid arthritis and appears to be an attractive, cost-effective approach to assessing and monitoring quantitatively the status of an individual patient.

Prediction of long-term mortality in patients with rheumatoid arthritis according to simple questionnaire and joint count measures.

OBJECTIVE: To describe mortality over 15 years in a cohort of patients with rheumatoid arthritis, according to a simple questionnaire and joint count. DESIGN: A cohort study with 15 years of follow-up. SETTING: University hospital outpatient clinic. PATIENTS: A cohort of 75 patients with rheumatoid arthritis. MEASUREMENTS: Quantitative baseline measures: demographic, articular (joint counts), clinical, questionnaire, and physical measures, including modified questionnaire and joint count measures with substantially fewer items. RESULTS: Although few deaths were seen in the first 3 years after baseline, the standard mortality ratio over 15 years was 1.62, similar to findings in other series. Significant predictors of mortality included age, formal education level, joint count, activities-of-daily-living questionnaire scores, disease adjustment scores, morning stiffness, comorbid cardiovascular disease, grip strength, modified walking time, and button test. Five-year survival in patients with the poorest status according to these quantitative measures was 40% to 60%, comparable to expected survival at that time of patients with three-vessel coronary artery disease or with stage 4 Hodgkin disease. Simplified measures, including a count using only 28 joints and a questionnaire using only 8 activities of daily living, were similar to the more elaborate traditional measures for predicting mortality. CONCLUSION: Higher mortality rates in patients with rheumatoid arthritis are predicted by more severe clinical disease, as in other chronic diseases. Severe rheumatoid arthritis may be identified using quantitative functional status questionnaires and joint counts, which can be ascertained in about 10 to 15 minutes in any clinical setting.

[Prevalence of psychiatric disorders in primary care using the PRIME-MD questionnaire].

OBJECTIVE: To quantify the frequency of psychiatric disorders detected by primary care doctors, using the PRIME-MD questionnaire, and by psychiatrists using a structured clinical interview. DESIGN: An observational, descriptive, crossover study, using a questionnaire. One of each two patients was selected until reaching the total number of patients. SETTING: The study was conducted in five primary care centres in Madrid. PATIENTS: To be included in the study, patients had to consent verbally, be able to understand the questions asked and have been previously diagnosed as psychotic or demented. 395 patients were recruited, of which 312 completed the study. INTERVENTIONS: The primary care doctor administered the PRIME-MD questionnaire to each patient, and then a psychiatrist conducted the SCAN interview. RESULTS: The time spent by the doctor on the PRIME-MD questionnaire was usually 10 minutes. The doctor had previously detected psychiatric pathology in 18.5% of his/her patients; with the PRIME-MD questionnaire he/she detected it in 53.5%. The psychiatrist with the SCAN detected psychiatric pathology in 41.3% of patients. CONCLUSIONS: The high frequency of psychiatric disorders in primary care patients and primary care doctors' lack of ability in detecting these disorders was confirmed by this study. The PRIME-MD questionnaire, an instrument for rapid detection of the most commonly found psychiatric disorders within primary care, may considerably improve this situation.

Evaluation of a screening questionnaire for genetic studies of Parkinson's disease.

A screening questionnaire with high sensitivity for detection of Parkinson's disease would make it easier to identify undiagnosed, yet affected, family members for genetic research. We assessed the validity of a screening questionnaire developed by Duarte et al. [1995: Mov Disord 10:643-649] with reported high specificity and sensitivity for Parkinson's disease (PD). We applied the questionnaire to 78 asymptomatic members of families that had at least two people diagnosed with PD. These families were participating in a linkage study of Parkinson's disease. Examination of these 78 revealed that 53 were normal (normal controls) and 25 were classified ("undiagnosed" PD defined) as possible, probable, or clinically definite PD based on standardized criteria. We compared these results with 123 patients with clinically definite PD ("diagnosed" PD). There were significant differences among the mean scores on the questionnaire for normal controls (4.4), subjects with undiagnosed PD (9.8), and patients with diagnosed PD (42.1; p<0.000001) and a significant difference between undiagnosed PD and normals (p<0.01). The questionnaire had only 4% sensitivity for detection of parkinsonism in undiagnosed PD using the original criteria [Duarte et al., 1995]. Revising the criteria increased the sensitivity from 4 to 48% in the undiagnosed group. The positive predictive value was 39% and the negative predictive value was 72%. Prospective application of these revised criteria is necessary to confirm the improved sensitivity. However, we conclude that this screening questionnaire has inadequate sensitivity for detection of mild parkinsonism and direct examination is still critical for accurate classification for genetic studies.

[The validity and reliability of a questionnaire for assessing the functional capacity of older persons].

OBJECTIVES: Our aim was to evaluate the validity and reliability of a questionnaire to measure the functional capacity in older people. DESIGN: Observational cross-sectional study. SETTING: Community level. Three basic health areas. PARTICIPANTS: 519 individuals over 64 selected by systematic random sampling taking as sampling units a list of household living at least an individual over 64 years. MEASUREMENTS AND MAIN RESULTS: A new questionnaire was developed starting from the OARS-MFAQ, the CVA. This new questionnaire is shorter but it maintains the same structure. Ten interviews were recorded in a videotape and subsequently analyzed and marked by four different observers to evaluate the inter-observer agreement. To assess the criterion validity the rates of 40 individuals in the CVA were compared with the rates assigned to the same individuals by experts in each area of the questionnaire (physical health, mental health, daily activities, economic resources, and social support). The criterion validity of the version to proxies of CVA (CVA-I) was studied comparing the answers in the CVA of 31 individuals and the answers given in the CVA-I by proxies of the same 31 individuals. The internal consistency in both versions of the questionnaire was studied in 519 individuals, agreement showed values of kappa coefficient between 0.43 and 0.69. Correlation coefficients Interobserver between expert's rates showed values between 0.54 and 0.74. Correlation coefficients between CVA and CVA-I showed values between 0.60 and 0.74 except in the social support dimension (0.16). The Cronbach alpha coefficient were 0.73 for CVA and 0.62 for CVA-I. CONCLUSIONS: The CVA questionnaire showed an acceptable validity and reliability except in the social support dimension of the CVA-I.

The development & characteristics of a physical activity questionnaire for epidemiological studies in urban middle class Indians.

A single page physical activity questionnaire was designed for use in epidemiological studies. The questionnaire estimates 24 h energy expenditure as well as components of occupation and discretionary leisure time activities. Estimates of physical activity were highly repeatable, when the questionnaire was re-administered within a 4 wk period (e.g., r = 0.86, P < 0.01 for 24 h energy expenditure). Relative validity was assessed by comparing energy intake (using repeated 24 h dietary recalls) and expenditure (using the physical activity questionnaire) over the same period. A correlate of r = 0.33, P < 0.05 between the two measures compared well with reports from literature. The discriminatory power of the questionnaire was assessed by comparing the physical activity patterns of young (18-30 yr) and older (> 60 yr), free living healthy subjects. The questionnaire provides a tool for the assessment of physical activity patterns of urban middle class Indians, which despite its importance has been inadequately studied so far.

Scoring the short form ICSmaleSF questionnaire. International Continence Society.

PURPOSE: The International Continence Society (ICS) ICSmale questionnaire was devised to provide a thorough evaluation of the occurrence and bothersomeness of lower urinary tract symptoms and their impact on the lives of men with benign prostatic disease. This report completes the developmental work on the questionnaire, producing the concise short form instrument, ICSmaleSF, with a valid, reliable and scientifically justified scoring system. MATERIALS AND METHODS: Two data sets were used. The short form version of the questionnaire was devised and initially evaluated using data on men with uncomplicated lower urinary tract symptoms who were involved in the CLasP randomized controlled trial comparing laser therapy with transurethral prostatic resection and conservative management or monitoring without active intervention. External validation of the scoring system was undertaken using data from phase II of the ICS benign prostatic hyperplasia (BPH) study, an observational study of outcome in men with lower urinary tract symptoms related to benign prostatic enlargement. All patients completed the developmental version of the ICSmale questionnaire. Parallel analysis on the CLasP data set identified items that were responsive to change or highly problematic, allowing other redundant and overlapping items to be eliminated. Factor analysis and Cronbach's alpha coefficients were used to examine the clustering of items. Regression models were used to investigate the validity of followup scores within and across treatment groups in the CLasP and ICS/BPH studies. RESULTS: The questionnaire, which originally comprised 22 items, was shortened to 11 items in the 2 distinct factors of voiding (ICSmaleVS) and incontinence (ICSmaleIS) symptoms. Cronbach's alpha coefficients were high at 0.76 for ICSmaleVS and 0.78 for ICSmaleIS. A simple additive score was calculated by adding the 5 items in ICSmaleVS and 6 in ICSmaleIS. ICSmaleVS and ICSmaleIS detected expected improvement in the laser therapy and transurethral prostatic resection groups, and stability in the conservative management group within CLasP. Similarly each subscore but particularly ICSmaleVS was sensitive to differences in the outcome of the range of treatments in the ICS/BPH study. While frequency and nocturia were highly problematic and sensitive to change individually, they did not load into the other main factors or correlate with each other. It is suggested that these symptoms should be evaluated separately with the additional inclusion of a single item measure of the impact of lower urinary tract symptoms on daily life. CONCLUSIONS: The ICSmaleSF represents a comprehensive, concise, valid and reliable instrument for evaluating men with lower urinary tract symptoms. Unlike other questionnaires in the field it contains subscores for the domains of voiding and incontinent symptoms as well as the separate consideration of frequency, nocturia and impact on daily life. We hope that it will become the tool of choice for the comprehensive evaluation of treatment of men with lower urinary tract symptoms associated with benign prostatic disease.

Relationship between patient practice-oriented knowledge and metabolic control in intensively treated Type 1 diabetic patients: results of the validation of the Knowledge and Practices Diabetes Questionnaire.

AIMS: To validate a newly developed questionnaire for the measurement of patients' knowledge and practices, with particular attention to its ability in predicting HbA1c levels. RESEARCH DESIGN AND METHODS: The Knowledge and Practices Diabetes Questionnaire (KPDQ) is a questionnaire composed of two scales, investigating patient knowledge and practices. Twenty-two questions, 12 dealing with patients' knowledge and 10 relative to patients' practices, were initially identified. Factor analysis and reliability analysis were used to validate the questionnaire. The ability of the two scales in predicting metabolic control was then evaluated. The questionnaire was administered to a population of Type 1 diabetic subjects intensively treated and regularly attending the diabetes outpatient clinic of Pescara General Hospital. The mean of all HbA1c measurements performed after patients were taken in charge by the clinic was used as an indicator of metabolic control. RESULTS: Out of 133 Type 1 patients identified, 77 (58 %) filled in the questionnaire. Respondents had a mean age (+/- SD) of 37 +/- 13 years and a mean diabetes duration of 13 +/- 9 years. The application of factor and reliability analyses led to the definition of two final scales composed of 10 (Knowledge Score, KS) and 5 items (Practice Score, PS), respectively. Item-scale correlation was > or = 0.40 for all the items investigated. Cronbach's alpha coefficient exceeded the value of 0.70 for both scales. The mean number of HbA1c determinations during a median period of observation of 4 years was of 11 +/- 5. The mean HbA1c value for the whole population was of 7.0% +/- 1.4, while the proportion of patients with values < or = 7.0% was of 57%. After adjusting for clinical and patient-related characteristics, the KS was the only independent predictor of metabolic control. Patients in the lowest quartile of the KS showed a more than 20-fold increased risk of having mean HbA1c values > or = 7.0% as opposed to those in the highest quartile (odds ratio, OR=23.3;p=0.009). No association emerged between metabolic control and PS. CONCLUSIONS: The KPDQ presents excellent psychometric properties. The KS also shows a very impressive association with the mean HbA1c values over a period of 4 years. These findings are particularly remarkable in that many studies have failed in documenting such a relationship. The KS can thus be considered as a quick and efficient screening tool to be used in an ambulatory setting to monitor the level of practice-oriented knowledge of patients with Type 1 diabetes as well as to identify those subjects who need individualized educational interventions.

[French translation and validation of the Edinburgh Questionnaire for the diagnosis of intermittent claudication].

Obliterative arterial disease of the lower limbs is diagnosed by simple, reproducible, sensitive and non-invasive methods. One of these, a questionnaire for the diagnosis on intermittent limping, is a method of choice. Until recent years, the only validated questionnaire was the one proposed by the World Health Organisation. This was criticised a lot, especially for its lack of sensitivity. Recently, a Scottish group proposed an improvement in the diagnostic performance of this questionnaire by carrying out several changes. This new version, called the Edinburgh Questionnaire, has promising diagnostic qualities. The authors present a French version of this questionnaire. This French translation was validated in 105 patients referred for diagnosis of obliterative lower limb arterial disease. A sensitivity of 86.5%, a specificity of 95.6%, a positive predictive value of 91.4% and a negative predictive value of 92.9% of this French version are comparable to the results obtained with the English version. Therefore, the authors suggest using this questionnaire in epidemiological and public health studies in France.

Theoretical assumptions and psychometric characteristics of the sense of personal control at work questionnaire.

UNLABELLED: Personal control is a very important determinant of stress experienced at work. This variable is taken into account in different models of stress, and its role in the relationship between stress and stress effects has been studied in many research projects. But there is still lack of in-depth theoretical considerations on various definitions of control, which would allow to develop precise operationalization of this phenomenon. The following issues are discussed in this paper: 1) theoretical assumptions important for proper construction of the Sense of Personal Control at Work (SPCW); 2) the origins of SPCW Questionnaire; 3) the results of empirical study on psychometric characteristics of the SPCW Questionnaire. A group of 160 subjects participated in the study; the SPCW Questionnaire was administered twice with a 2-week interval; at the first stage, it was used together with other instruments, such as Maslach Burnout Inventory, Stress at Work Questionnaire, Work Satisfaction Scale, general Health Questionnaire-28. Reliability coefficients: Cronbach alpha = 0.81; r(tt) = 0.69. VALIDITY: correlation coefficients between personal control and work satisfaction r = 0.44; stress at work r = -0.33; emotional exhaustion r = -0.28; personal accomplishment r = 0.25; depersonalisation r = 4.26; mental health r = -0.19. Exploratory factors analysis have not confirmed theoretical structure of the SPCW Questionnaire.

A standardized open-ended questionnaire as a substitute for a personal interview in dental admissions.

This paper discusses the need for reliable and valid measures of personality and motivational factors in the prediction of success and attrition in a dental school. The admissions system currently used in most schools includes personality factors that are measured by an interview. Our study examined whether the interview could be replaced by a standardized, open-ended questionnaire, thus increasing standardization and objectivity and avoiding the possible biases of the interview. The relationship between the standardized questionnaire score and the interview score in a dental school in Israel was examined, as well as the relationship between the standardized questionnaire score and the admissions decisions. The results showed that the questionnaire and the interview probably measure a common construct, enabling us to tentatively recommend a two-stage admissions process: all candidates meeting certain academic criteria should be asked to answer the questionnaire; those candidates scoring above a certain percentile on the questionnaire should either be admitted outright or invited for an interview.

A simple questionnaire to detect hypermobility: an adjunct to the assessment of patients with diffuse musculoskeletal pain.

The aim of the study was to develop a simple and reproducible self-reporting questionnaire that identifies individuals with hypermobility. Two hundred and twelve consecutive hypermobile female new attendees to the hypermobility clinic at two London teaching hospitals and a random selection of 57 healthy volunteers completed a 10-part questionnaire. Questions were selected from clinical experience (RG), and assessed musculoskeletal symptoms and past and present physical agility. Of the 212 cases, 30 were hypermobile with no other underlying disorder and 182 fulfilled the 1998 Brighton criteria for benign joint hypermobility syndrome (BJHS). Odds ratios for the presence of hypermobility were calculated for each question. Six questions were found to be significant and the model of 'best fit' for sensitivity and specificity contained five of these. To demonstrate the reproducibility of the five-part questionnaire a second cohort of 170 hypermobile cases with BJHS and 50 controls was surveyed. Analysis demonstrated that a positive answer to any two questions in the five-part questionnaire gave the highest combined sensitivity and specificity for detecting hypermobility. The sensitivity and specificity was 84% and 89% respectively in the first cohort and reproduced with values of 84% and 80% in the second cohort. Overall the questionnaire correctly identified 84% of all cases and controls. This simple and reproducible questionnaire for detecting hypermobility could be of particular use as an adjunct in the clinical assessment of chronic, diffuse pain syndromes where hypermobility is often missed yet is potentially treatable.

Quality of life in women with fibromyalgia syndrome: validation of the QIF, the French version of the fibromyalgia impact questionnaire.

OBJECTIVE: To validate a translated and adapted version of the Fibromyalgia Impact Questionnaire (FIQ) for use in French-speaking populations. METHODS: The FIQ was translated into French by 2 independent translators and then back-translated into English to assess the conceptual equivalence. The translated version was tested and adapted by an expert committee to obtain the Questionnaire de mesure d'Impact de la Fibromyalgie (QIF), the French version of the FIQ. We administered the QIF to 102 women with fibromyalgia (FM): 71 women who consulted once, and 31 women who were follow for 3 visits (D0, M1, and M3). The patients were also asked to answer 4 other questionnaires: the McGill Pain Questionnaire, the Medical Outcome Study Short Form-36 (SF-36), the short form of the Arthritis Impact Measurement Scale 2 (AIMS2), and the General Health Questionnaire (GHQ) (for psychiatric assessment). To ensure test-retest reliability, the patients were asked to complete the QIF 7 days after the first visit and to send it back to the investigators by mail. During each visit, all patients were asked about pain intensity. A tender point count was obtained by thumb palpation and the tenderness threshold of each specific point was assessed by a 4-point scale score to determine the global tender point index. RESULTS: No major cultural adaptation was needed to obtain the French version of the FIQ. Test-retest reliability coefficients (intraclass correlation coefficient) for each question ranged from 0.04 to 0.84. Two items from the QIF (number of days when the patient felt good and visual analog scale stiffness) did not reach significant levels of test-retest reliability. Internal validity was good. The QIF score correlated well with the SF-36 and AIMS2 scores. The psychological aspects of the QIF were well correlated with those of GHQ-28. None of the items from the McGill Pain Questionnaire was correlated with QIF items. Similarly the clinical data concerning pain assessment were not correlated with QIF items. CONCLUSIONS: QIF is a valid instrument for measuring functional disability and health status in French women with FM. Some of the items were of a limited reliability, perhaps due to the variability of the multiple aspects of this syndrome.

[Criteria validation of the Roland Morris questionnaire. A Danish translation of the international scale for the assessment of functional level in patients with low back pain and sciatica].

INTRODUCTION: The main concern of patients with low back pain is the functional limitation which the symptoms cause. Therefore it is important to find a valid tool by means of which their functional level can be assessed. The aim of this study was to validate the first Danish translation of the Roland Morris Questionnaire (RMQ), which evaluates the functional level of activity of patients with low back pain and possible sciatica. The RMQ was compared with the functional scale of a Danish functional and pain level questionnaire, The Low Back Pain Rating Scale (RS), and the functional scale (PF) of the SF-36. MATERIAL AND METHODS: Independently, three professionals made a retroversion of the RMQ. Then 135 patients with lumbar disc herniation completed the RMQ, RS and the SF-36. The patients comprised 47% women and 53% men with an average age of 43 years. RESULTS: A significant correlation between the RMQ and the other two questionnaires was found. RMQ-RS; r = 0.89, p < or = 0.001, RMQ-PF (SF-36); r = -0.88 p < or = 0.001. A Chronbach Alpha showed a value of 0.94 (scale 0-1). Differences in scores between the three questionnaires were within the 95% limits of agreement. The average RMQ score was 10% higher than the score of RS and PF (SF-36). CONCLUSION: According to this study the RMQ can be used as a valid tool in the assessment of the functional level of patients with lumbar pain and previous lumbar herniation. Due to the fact that the questionnaire is fast and easy to complete, it is valid, reliable and sensitive and widely used internationally. We recommend the questionnaire to be used as a supplement to the clinical examination both in clinical practice and in research.
