Validation of a computer version of the patient-administered Danish prostatic symptom score questionnaire

OBJECTIVE: To validate a computer version of the Danish Prostatic Symptom Score (DAN-PSS) questionnaire and compare it with the paper version. MATERIAL AND METHODS: Ninety-three male patients (aged 25-87 years), referred to a department of urology for lower urinary tract symptoms (LUTS), filled in a personal computer (PC) version and a paper version of the DAN-PSS questionnaire. Subsequently they answered a questionnaire concerning their preferences and computer experience. RESULTS: A fair correlation between the total scores from the paper and PC versions was found. The differences were independent of both total score and age. In the PC version all LUTS questions were answered while 9.8% were left blank in the paper version. The sexual questions were answered by 71% of patients in the paper version and by 87.5% in the PC version. For the questions in the PC version a learning curve was observed in terms of the time taken to answer the questions. Previous computer experience did not influence answering time, difference in score between paper and PC versions or total score. Almost all patients preferred the PC version to the paper version. CONCLUSION: The PC scores are reasonably reliable judging by comparison with previously validated traditional paper scores. The PC questionnaire had a higher response rate and was preferred by the majority of patients.

Validation of the Tunisian version of the Roland-Morris questionnaire

Our aim was to validate a culturally adapted, Tunisian-language version of the Roland-Morris Disability Questionnaire (RMDQ), which is a reliable evaluation instrument for low-back-pain disability. A total of 62 patients with low back pain were assessed by the questionnaire. Reliability for the 1-week test/re-test was assessed by a construction of a Bland Altman plot. Internal construct validity was assessed by Cronbachs test. External construct validity was assessed by association with pain, the Schober test and the General Function Score. Sensitivity to change was determined using a t-test for paired data to compare RMDQ scores at inclusion and at completion of the therapeutic sequence of local corticosteroid injections. We also compared the questionnaire score with the General Function Score, both taken after completion of the therapeutic sequence. The constructed Bland Altman plot showed good reliability. Internal consistency of the RMDQ was found to be very good and the Cronbachs test was 0.94, indicating a good internal construct validity. The questionnaire is correlated with the pain visual analogue scale (r=33; p=0.0001), with the Schober test (r=0.27; p=0.0001) and the General Function Score (r=56; p=0.0001) indicating an adequate external construct validity. The RMDQ administered after the therapeutic sequence is sensitive to change (r=0.83; p=0.000). Comparison of the questionnaire score to the General Function Score, after completion of the therapeutic sequence, was satisfactory (r=0.75; p=0.000). We conclude that the Tunisian version of the Roland-Morris questionnaire has good reliability and internal consistency. Furthermore, it has a good internal- and external construct validity and high sensitivity to change. It is an adequate and useful tool for assessing low-back-pain disability.

Validation of the Danish version of the revised cystic fibrosis quality of life questionnaire in adolescents and adults (CFQ-R14+)

BackgroundQuality of life is an important parameter in the evaluation of quality and outcome of health care and treatment, especially in patients with chronic disorders. The aim of this study was to assess the validity and reliability of the Danish version of the revised disease-specific health-related quality of life questionnaire for adolescents and adults with cystic fibrosis (CFQ-R14+).MethodsA total of 196 cystic fibrosis (CF) patients completed the CFQ-R14+ (response rate 71%). Forced expiratory volume in 1 s in percentage of predicted (FEV₁%) and body mass index (BMI) were included as measures of health status.ResultsInternal consistency coefficients ranged from 0.54 to 0.95. Eight out of the twelve scales had alpha coefficients above 0.7. Test–retest correlations ranged from 0.42 to 0.88 and they were significant in eight scales. All the CFQ-R+14 scales except the digestive symptoms scale discriminated significantly (p < 0.05) between patients with mild, moderate, and severe disease. Nine out of the twelve scales discriminated significantly (p < 0.05) between nourished (BMI ≥ 19) and malnourished (BMI < 19) patients. Significant differences between participants and non-responders were found for age, sex and FEV₁ (higher age, more males and lower FEV₁ among non-responders). All of the scales met standards for floor effects (< 15% of the responders with the lowest score) but five of the scales failed to meet standards for ceiling effects (> 15% of the responders with the highest score).ConclusionThe Danish CFQ-R14+ is a reliable and valid instrument for measuring the health-related quality of life in Danish adolescents and adults with CF, though with the exception from a few of its subscales.

Validation of a pre-anaesthetic screening questionnaire

Summary We developed a screening questionnaire to be used by nurses to decide which patients should see an anaesthetist for further evaluation before the day of surgery. Our objective was to measure the accuracy of responses to the questionnaire. Agreement between questionnaire responses and the anaesthetist's assessment was assessed. For questions with a prevalence of 5 to 95%, the Kappa coefficient was used; percentage agreement was used for all other questions. Criterion validity was excellent/good for all questions with a prevalence between 5 and 95%, except for the question ‘Do you have kidney disease?’ For questions with prevalence < 5%, all demonstrated adequate criterion validity except the questions ‘Has anyone in your family had a problem following an anaesthetic?’ and ‘If you have been put to sleep for an operation were there any anaesthetic problems?’ Therefore, it is reasonable for nurses to use this questionnaire to determine which patients an anaesthetist should see before the day of surgery.     

Translation and validation of the Danish version of the Patient Rated Wrist Evaluation questionnaire

Abstract

The need for validated outcome measures is increasing. The purpose is to translate and validate the Patient Rated Wrist Evaluation (PRWE) in Danish. Translation was done by an expert panel followed by evaluation of a lay panel and a field test on 10 patients. Sixty patients with wrist fractures were included. Both lay panel comments and field test revealed issues not dealt with by the expert panel, and a final version of the Danish PRWE was made. The validation process then continued and reliability results. were presented as Cronbach's alpha = 0.94, describing the homogeneity and the intraclass correlation coefficient = 0.88 and difference of mean = 5.7 (CI = 1.12–10.37, p = 0.017), describing the concordance of the results. Convergent validity at first and last control was for pain, 0.51 and 0.46, and physical mobility, 0.56 and 0.64, respectively, describing the correlation with a gold standard questionnaire. A minor floor effect was noticed, but not enough to indicate a lack of sensitivity of the PRWE. Effect size, the ability to measure sensitivity to change, was 0.62, also described as responsiveness. The translation resulted in a questionnaire that represents correct easy-understandable Danish. It is concluded that the modified Danish version is a valid questionnaire for patients with wrist fractures.

Combined posterior–anterior stabilisation of thoracolumbar injuries utilising a vertebral body replacing implant

The authors report on a prospectively followed series of 35 patients with injuries of the thoracolumbar spine from T7 to L3. The radiological course after combined posterior–anterior surgery with anterior column reconstruction with a distractible vertebral body replacing implant demonstrated a stable reconstruction technique with almost no re-kyphosing. In 18/18 patients with CT follow-up intervertebral fusion was observed as bony bridging lateral to the VBR implant. The functional/clinical outcome of the patients was analysed with a set of eight validated outcome scales. After an average follow-up period of 2½ years encouraging results were noticed. The neurological improvement rate (≥1 Frankel/ASIA grade) was 8/12 patients (67%) with a complete recovery in 6 cases. 17/29 patients returned to former occupation; 20/29 patients returned to former leisure activities; 24/28 patients rated their general outcome as “unlimited and pain free” or “occasionally and/or mild complaints” with a VAS score of >80 (scale 0–100). The psychometric questionnaires revealed good results with strong correlation comparing the different scoring systems statistically: mean McGill Pain Questionnaire 12.5 (0–40); mean Oswestry Disability Index 20% (0–51). 13/29 patients scored <4 in the Roland and Morris Disability Questionnaire. The German back pain questionnaire (Funktionsfragebogen Hannover Rücken) showed a mean “functional capacity” of 75%, corresponding with moderate restriction. We concluded the presented method as highly effective to completely reduce and maintain an anatomic spinal alignment. The outcome tended to be better in comparison with non-operatively treated patients as well as with norm populations with low back pain.
