Detecting exacerbations using the Clinical COPD Questionnaire

Background  

Early treatment of COPD exacerbations has shown to be important. Despite a non-negligible negative impact on health related quality of life, a large proportion of these episodes is not reported (no change in treatment). Little is known whether (low burden) strategies are able to capture these unreported exacerbations.

The UK version of the Seattle Angina Questionnaire (SAQ-UK): reliability, validity and responsiveness

The study assesses the reliability, validity and responsiveness of the UK version of the Seattle Angina Questionnaire (SAQ-UK). The instrument was anglicised and administered by self-completed postal questionnaire to 959 patients recruited from general practices in the North East of England. A total of 655 (68.3%) patients returned a completed questionnaire. Principal component analysis produced three important dimensions: physical limitations, anginal frequency and perception and treatment satisfaction. Four items that performed poorly were removed from the instrument. The removal of items greatly increased the number of computable scale scores. Estimates of internal reliability for the three dimensions ranged from 0.83-0.92. Estimates of test-retest reliability were above accepted standards. The correlation between the SAQ-UK scores and the SF-12, EuroQol and health transition was evidence for the validity of the instrument. The SAQ-UK produced responsiveness statistics that were comparable to the parent instrument and was more responsive to improvements in health than the generic instruments. The SAQ-UK is recommended as a measure of health outcome for the evaluation of angina management.

Reliability, validity and responsiveness of the German Short Musculoskeletal Function Assessment Questionnaire in patients undergoing surgical or conservative inpatient treatment

Objective: The patient-based evaluation of outcome is gaining increased importance. The aim of the study was to demonstrate the reliability, validity and responsiveness of the German version of the Short Musculoskeletal Function Assessment Questionnaire (SMFA-D) in patients undergoing surgical or conservative treatment. Methods: Three hundred and thirty-two patients suffering from osteoarthritis of the hip or knee, rheumatoid arthritis or rotator cuff tear undergoing surgical or medical inpatient treatment were followed up for 12 month. Patients underwent both SMFA-D and other assessments and clinical as well as radiological examinations. Reliability, validity and responsiveness of the SMFA-D were evaluated. Results: Values of the SMFA-D subscales, Function index (M 22–49, SD 12–20, range 0–96) and Bother index (M 29–52, SD 15–23, range 0–100), showed a normal distribution. Internal consistency (0.88–0.97) and retest reliability (0.71–0.96) coefficients were satisfactory to excellent. In most cases, the SMFA-D correlated significantly with function tests, physicians’ function ratings, patients’ pain ratings and other quality-of-life questionnaires in all patient subgroups. The results support both the construct and criterion validity of the measure. Different patient groups and subgroups could be discriminated with the SMFA-D scales. The standardized response means of SMFA-D subscales were in surgical patients better than in conservatively treated patients and comparable to those of the SF-36 Physical Component Summary scale. Conclusions: The German version of SMFA is a reliable, valid and responsive questionnaire in patients with osteoarthritis of the hip or knee, rheumatoid arthritis or rotator cuff tear undergoing surgical or medical inpatient treatment. Thus, the use of the SMFA-D in these patients can be recommended.     

Reliability and validity of the Functional Status Questionnaire

The Functional Status Questionnaire (FSQ) originally was developed to allow the comprehensive and efficient assessment of physical, psychosocial, social, and role functioning in ambulatory patients. It is a self-administered survey that takes approximately 15 min to complete and can be scored to produce a one-page report for clinicians to use in their practices. It has been translated into Swedish, French, and German. Since the FSQ was first published, it has been used in a variety of other settings, including assessment of the impact of variations in hospital practice patterns, the study of relationships between hospital processes of care and outcomes, and other applications, including randomized controlled trials of pharmaceuticals. In this paper we provide selected data on the reliability and validity of the FSQ in different populations. Many of the data are from previously published studies. However, because of the emphasis of this issue of Quality of Life Research, we also present new data from two large studies of persons over the age of 65.     

Development and content validity of the Norwegian Self-Assessment of Modes Questionnaire (N-SAMQ)

Background: The Intentional Relationship Model (IRM) introduced six therapeutic modes as ways of relating to clients. By increasing occupational therapists’ awareness of modes, and by increasing their skills in using them, therapists may improve their interactions with clients. The Self-Assessment of Modes Questionnaire may assist in increasing awareness of modes. Aim: To describe the process of developing a Norwegian version of the Self-Assessment of Modes Questionnaire (N-SAMQ) and to evaluate its content validity. Materials and methods: A 10-step translation and adaptation procedure was followed. Occupational therapists working in diverse practice areas completed the preliminary N-SAMQ version. Individual cognitive interviews were performed with these therapists in order to examine the comprehensibility and cultural appropriateness of the N-SAMQ. Results: Initially, one item was omitted. Following the pilot study (n?=?7), two of the remaining items were modified with a view to increasing their cultural relevance. Otherwise, modifications were made mostly in terms of words and phrasing. Conclusion: The N-SAMQ appears to have good face and content validity. Significance: With the N-SAMQ, Norwegian occupational therapists can assess their preferred therapeutic modes.

The COPD Italian Lung Information Needs Questionnaire (LINQ): Development,preliminary validation,and findings

Chronic obstructive pulmonary disease (COPD) patients have poor knowledge about the disease. Until now, it has not been possible to check the information needs of these patients. The Lung Information Needs Questionnaire (LINQ), however, could fill this particular need. The aims of this study were to identify patient perceptions about COPD, and what information patients need, and to verify whether the questionnaire is comprehensible. Data demonstrate that LINQ is easily understood: 82% answered all questions with “I have properly understood the question”. LINQ is quick to apply (approx. 6 min to complete). Sixty-seven per cent of patients had incorrect knowledge about their prognosis. Thirty-six per cent did not know when to call an ambulance. Eight per cent of smokers said that no one had ever told them to stop smoking. Compliance with therapy results was not sufficient. Patients had poor knowledge of the causes of COPD, and they knew little about the whys and wherefores of COPD treatment. LINQ represents a valid means of investigating patients afflicted with COPD and managing pathology control by the doctor and by the patient. LINQ represents a fundamental means of investigating otherwise-unknown COPD issues.

The Patient Experiences Questionnaire: development, validity and reliability.

OBJECTIVE: . To describe the development of the Patient Experiences Questionnaire (PEQ) and to evaluate reliability and validity of constructed summed rating scales. DESIGN: Literature review, focus groups and pilot surveys. Two national cross-sectional studies performed in 1996 and 1998. SETTING: Two postal surveys in a national sample of 14 hospitals stratified by geographical region and hospital size. Subjects. Patients consecutively discharged from surgical wards and wards of internal medicine. The surveys included 36 845 patients and 19 578 responded (53%). RESULTS: We constructed 10 summed rating scales based on factor analysis and theoretical considerations: Information on future complaints, Nursing services, Communication, Information examinations, Contact with next-of-kin, Doctor services, Hospital and equipment, Information medication, Organization and General satisfaction. Eight scales had a Cronbach alpha coefficient of >0.70, the remaining two were >0.60. Repeatability was >0.70 for five scales and >0.60 for the remaining scales. CONCLUSIONS: The PEQ is a self-report instrument covering the most important subjects of interest to hospital patients. Results are presented as 10 scales with good validity and reliability. It emphasizes practicability and comprehensibility while at the same time providing sufficient information about domains applicable to most patients admitted to medical and surgical wards.

Italian translation of the Manchester-Oxford Foot Questionnaire, with re-assessment of reliability and validity

Purpose  To cross-culturally adapt and validate the Italian version of the Manchester-Oxford Foot Questionnaire (MOXFQ) in patients affected by hallux valgus. Methods  The MOXFQ was translated into Italian and culturally adapted following the forward and backward translation method. A sample of 172 patients with hallux valgus was asked to fill in the MOXFQ and the Short-Form 36 Health Survey (SF-36). Two-week retest was performed on a random sub-sample of 40 patients. Internal consistency and test–retest reliability were assessed using Cronbach’s alpha and intraclass correlation coefficient (ICC), respectively. Construct validity was assessed with the use of Spearman’s rank correlation coefficient, using a priori hypothesized correlations with SF-36 domains. Results  The internal consistency reliability was acceptable for all MOXFQ domains (Pain, Walking/standing and Social interaction) with Cronbachs’ alpha coefficients ranging from 0.72 to 0.83. The assessment of test–retest reliability reveals satisfactory values with ICCs ranging from 0.85 to 0.92. Construct validity was supported by the presence of all the hypothesized correlation, with the exception of Italian Walking/standing domain with the SF-36 Role-Physical domain (ρ = −0.29). Conclusions  The Italian version of MOXFQ is a valid and reliable instrument for evaluating foot pain and functional status in patients affected by hallux valgus.     

Development of a Korean version of the Cancer Therapy Satisfaction Questionnaire (CTSQ): cross-cultural adaptation, reliability, and validity

Purpose

(1) To translate original English Cancer Therapy Satisfaction Questionnaire (CTSQ) into Korean and perform validation, (2) to compare CTSQ domains of expectations of therapy (ET), feelings about side effects (FSE), and satisfaction with therapy (SWT) by cancer therapy type.

Methods

Cross-cultural adaptation was performed according to guidelines: translation, back translation, focus-group, and field test. We performed validation with internal consistency by Cronbach’s alpha and construct validity by exploratory factor analysis (EFA) with varimax rotation method. We compared each CTSQ domain between traditional Korean Medicine (TKM) and integrative cancer therapy (ICT) of combining western and TKM by two-sample t test.

Results

Cross-cultural adaptation produced no major modifications in the items and domains. A total of 102 outpatients were participated. Mean age was 51.9 ± 12.4. Most were stage 4 (74.4 %) cancer. Mean scores of ET, FSE, and SWT were 81.2 ± 15.7, 79.5 ± 22.9, and 75.7 ± 14.8, respectively. Cronbach’s alpha of ET, FSE, and SWT were 0.86, 0.78, and 0.74, respectively. EFA loaded items on the three domains, which is very close to that of the original CTSQ. ET and SWT was similar, but FSE was significantly higher in TKM than ICT (87.5 ± 19.3 vs. 74.9 ± 23.5; p = 0.0054).

Conclusions

Cross-cultural adaptation was successful, and the adapted Korean CTSQ demonstrated good internal consistency and construct validity. Similar expectation and satisfaction was shown between the two types of therapy, but patient’s reported feelings about side effects was significantly lower in patients receiving TKM than receiving ICT. Korean version of CTSQ can be used to evaluate Korean cancer patient’s experiences receiving various cancer therapy types.     

Measuring progress in clinical governance: assessing the reliability and validity of the Clinical Governance Climate Questionnaire.

Despite a lack of conceptual clarity, the importance of cultural change to clinical governance is widely accepted. While generic measures of organizational performance, culture and climate are available, their relationship to clinical governance is unclear. Consequently, there is currently no valid and reliable measure of clinical governance climate. This study aimed to address the deficiency by reducing a pool of clinical governance climate indicators developed via previous qualitative research, describing a latent factor structure and assessing the internal consistency and external validity of the factor model. The resultant instrument, the Clinical Governance Climate Questionnaire (CGCQ), attained high internal consistency and external (discriminant and construct) validity in a study population of healthcare Trust staff. It consists of 60 items distributed across six sub-scales of clinical governance: planned and integrated quality improvement; proactive risk management; absence of unjust blame and punishment; working with colleagues; training and development; and organizational learning. The measure enables those charged with leading the clinical governance agenda in UK healthcare organizations to assess the progress of organizational development initiatives, highlighting areas requiring particular attention. They might also be of interest to those concerned about the negative unintended consequences of performance management.

Validity,reliability, and responsiveness of the Kansas City Cardiomyopathy Questionnaire in anemic heart failure patients

Background While generic health status measures quantify the impact of all patients’ diseases on their health-related quality of life, disease specific measures focus on only one of the many conditions that a patient may have. If a patient has two diseases with similar clinical manifestations, they may respond differently to a disease-specific instrument if one of their conditions improves while the other worsens or remains stable, thus undermining the instruments in that patient population. We sought empirical evidence of the reliability and validity (including responsiveness) of the Kansas City Cardiomyopathy Questionnaire (KCCQ), a disease-specific measure for heart failure (HF), among HF patients with and without anemia, a condition that has similar symptoms to HF. Methods This work used a prospective cohort study of 811 HF outpatients from 58 U.S. centers with a baseline assessment of anemia of whom 698 were followed for 3 months with serial health status measures. Results Among participants, 268 (33%) were anemic. The construct validity of the KCCQ was supported by showing similar correlations with the New York Heart Association (NYHA) classification in patients with and without anemia (P value for interaction = 0.38). The internal consistency (Cronbach’s alpha = 0.92 and 0.93 for anemic and non-anemic patients, respectively) and test–retest reliability (mean 3-month change scores in stable patients = −2.8 [SD = 1.4] and −0.5 [SD = 0.8], P = 0.14) were similar. Estimates of responsiveness were also similar. Conclusion This study provides empirical evidence that the psychometric properties of the KCCQ are similar in patients with or without anemia, a potentially confounding clinical condition in patients with heart failure.
