Evaluation of the response of a questionnaire study by using the GIS and standard statistical methods.

This study is a part of a larger project Nr. NJ 6139-3 funded by the Grant Agency of the Czech Ministry of Health. The aim of the paper was to analyse the response rate using standard statistical methods and the Geographical Information System (GIS); to indicate differences in the response by sex, age, education, and employment; to determine the breakpoint for the collection of questionnaires according to which we can estimate the total response rate; to indicate whether the study sample was representative enough to generalize the project results. The additional aim of the paper was to collect those background literary sources dealing with the response rate as a methodological paradigm. The statistical and GIS analysis were based on comparison of the total population data (Census 2001), the study sample and the sample of the completed questionnaires data in the 23 districts of the city of Ostrava. The information from the data collection was derived from the date of receipt for each questionnaire. The literature sources were obtained from the Internet--in total 228 papers from the period since 1986 to the present have been checked. The main results of this study are: the GIS analysis was confirmed in all stages by standard statistical methods--it can therefore be used as a valid tool for quick orientation in data and for the comparison of a study sample with the general population; we did not find significant differences in the course of the collection of the questionnaires between sex, age, education, and the employment of respondents; it can be seen that the breakpoint according to which we can estimate the total response rate, is the 10th day after the questionnaires are distributed by post (75% of the questionnaires collected); our sample is representative enough from the geographical point of view.

Comparative validity of two hearing loss screening questionnaires.

BACKGROUND: Hearing loss is one of the most common of all physical impairments, but physicians seldom screen adults for it, and patients often overlook or deny hearing problems. This study was designed to validate the use of two self-administered hearing loss questionnaires. METHODS: Two self-administered screening questionnaires and a hearing screening evaluation using the Welch Allyn Audioscope 3 instrument were given to 409 consecutive family practice patients over the age of 18 years. Correlational, discriminate, sensitivity, and specificity analyses were conducted on the data. RESULTS: Neither of the existing questionnaires was clinically sensitive enough to be recommended for use. A new tool based on a discriminate function analysis of the existing questionnaires was developed. In contrast, the audioscope proved to be a sensitive screening tool. Of those patients who were identified, 88% did not follow recommendations to obtain further evaluation. CONCLUSIONS: Existing self-administered questionnaires cannot be recommended for use. A controlled clinical study using the newly derived questionnaire, the Smith Hearing Screening, should be conducted.

[Use of the Minnesota Living With Heart Failure Quality of Life Questionnaire in Spain].

INTRODUCTION AND OBJECTIVES: Quality of life is an important end-point in heart failure studies, as well as mortality and hospitalization rates. The Minnesota Living With Heart Failure Questionnaire is the instrument used most widely to evaluate quality of life in research studies. We used this questionnaire to evaluate quality of life in a general population attended by a heart failure unit in Spain. PATIENTS AND METHOD: 326 patients seen for the first time at the unit were evaluated. We analyzed the relationship between the questionnaire score and different clinical and demographic factors. RESULTS: The median global score on the Minnesota Living With Heart Failure Questionnaire was relatively low (28). We found a strong correlation (P<.001) between the score and functional class, sex (women had higher scores), and diabetes. We also found a correlation between the score and number of hospital admissions in the previous year (P<.001), anemia (P<.001) and etiology (P=.01), and a weak trend toward higher scores with increasing age (P=.04). The highest scores were observed in patients with valve disease disorders (43), and the lowest were seen in patients with alcoholic cardiomyopathy (20) and ischemic heart disease (24). We found no correlation with time of evolution of heart failure or with left ventricular ejection fraction. CONCLUSIONS: The scores on the Minnesota Living With Heart Failure Questionnaire in a general population attended by a heart failure unit in Spain were relatively low. However, we found a strong correlation between this score and functional class, and also between this score and number of admissions in the previous year. These results suggest that the questionnaire adequately reflects the severity of the disease.

Reliability and accuracy of a cardiovascular risk questionnaire and body shape figures for body size in Mexican obese subjects.

UNLABELLED: There is little information about the validity of questionnaires used by research related to obesity. The aim of this study was to demonstrate the reliability and accuracy of a cardiovascular risk questionnaire and perception of body size pictorials (BSP) measured in Mexican obese subjects. This was a cross-sectional study designed as two independent phases. The aims were: a) To calculate a concordance index between questionnaires and clinical records. b) To measure the reliability of the questionnaire and BSP by test-retest. Phase one: Eighty-four subjects were invited to answer the questionnaire (the average age was 46.1 +/- 14.9 years, BMI 36.4 +/- 7.2). The concordance obtained for heart attack, type 2 diabetes mellitus and high blood pressure was greater than kappa 0.6. High uric acid, hypercholesterolemia and hypertriglyceridemia showed low concordance. Phase two: One hundred and two subjects were invited (the average age was 50.8 +/- 14.4 years, IMC 35.6 +/- 6.8). A high concordance in test-retest (ri = 0.71, p < 0.001) and for correlation coefficients between BSP and BMI (r = 0.72, p < 0.01) was found. CONCLUSION: These data suggest that this questionnaire is reliable and data regarding diagnosis of type 2 diabetes mellitus, heart attack and high blood pressure are accurate in people who have been treated in hospital. Obese subjects are able to classify with accuracy their own BSP and that of other individuals. This kind of perception was not altered.

[Development of a questionnaire for the assessment and quantification of overweight and obesity related lifestyles].

INTRODUCTION: Lifestyle intervention is mandatory for obesity treatment. The aim of this study is to design a questionnaire to describe and quantify those behaviours more closely related to obesity in the Spanish obese population. METHODS AND PROCEDURES: An expert panel designed a preliminary 57 Liker-type item questionnaire, which was self-administered to 335 overweight patients (110 male, 225 female; age, 42 +/- 14 years; BMI, 32.6 +/- 3.7 kg/m2). After a subjacent dimensionality searching and item reducing first phase, a shrunk questionnaire of 24 items was then self-administered to 156 overweight patients (52 male, 104 female; age 42 +/- 12 years; BMI, 33.1 +/- 3.5 kg/m2); 56 of those patients were re-administered the questionnaire in order to provide test-retest information. RESULTS: Final questionnaire includes 22 items clustered in five dimensions: diet caloric intake, searching for psychological well-being eating, physical activity, healthy eating and alcohol intake. Proposed factorial structure is mostly reproduced in different samples and using different extraction methods: all dimensions but alcohol intake score alpha values > 0.75 for liability; test-retest stability is greater than 0.90 in all dimensions but alcohol intake; results for all validity tests performed (of construct, of content and discriminative) are highly satisfactory. CONCLUSION: Metrics study results (liability and validity) demonstrate that the proposed questionnaire provides an excellent tool to assess those lifestyles related to obesity control.

A questionnaire on sleep and mental disorders in Parkinson's disease (QSMDPD): development and application of a new screening tool.

Psychiatric, cognitive and sleep disorders are the most frequent and disabling non-motor complications of Parkinson's disease (PD). To improve the description of sleep and mental disorders in PD patients, we set out to develop a simple and reliable data collection tool (questionnaire) for the screening of large samples of PD patients. The first draft of the questionnaire was administered to a consecutive series of 120 PD patients from the outpatient department of our unit, who were instructed to fill it in with the help of their caregivers. Subsequent drafts of the questionnaire were evaluated together with the patients and their caregivers, until a final, satisfactory version was obtained. This final version was named the Questionnaire on Sleep and Mental Disorders in PD (QSMDPD). This questionnaire--we used the Italian version, named Questionario sui Disturbi del Sonno e Mentali nella Malattia di Parkinson, ODSMMP--consists of 119 questions with multiple-choice answers. The QSMDPD was mailed or handed to 400 PD patients followed at our unit's outpatient department. Three hundred and twenty (80%) were returned to us. A review of these completed questionnaires, conducted by a neurologist together with the patients, showed 90% of them (289) to be complete and to provide reliable data. This high compliance suggests that the QSMDPD is a promising tool for collecting data on sleep and mental disorders in large samples of PD patients. A short version will be administered as a follow-up tool.

[Validation of a screening questionnaire for stroke detection in Spanish-speaking communities].

OBJECTIVE: To evaluate the accuracy of an screening questionnaire for stroke detection in speaking-speaking communities. PATIENTS AND METHODS: We performed a door-to-door survey in Atahualpa (a rural community in coastal Ecuador) using a modified version of the Spanish translation of the OMS questionnaire for stroke detection. Subjects suspected of having a stroke as well as a 2% sample of negative subjects were evaluated by neurologists to evaluate sensitivity, specificity, and predictive value of the questionnaire and that of each of its questions. RESULTS: We found 18 possible cases among 1,568 individuals around 15 years old. Of these, 10 were confirmed stroke patients and 8 were false-positive (crude stroke prevalence of 6.38 per 1,000). We did not find false-negative cases. Sensitivity of the questionnaire was 100%, specificity was 99.5%, positive predictive value was 0.55 and negative predictive value was 1. The accuracy of each question as well as the number of questions answered as affirmative were different between patients and false-positive cases. CONCLUSIONS: The current questionnaire is highly sensitive but its positive predictive value is poor. This causes problems in large-scale studies, as the detection of many false-positives may compromise its viability. We propose a modification of the questionnaire that will turn it more accurate.

[Questionnaire and pad-test in assessment of incontinence after radical retro-pubic prostatectomy].

OBJECTIVE: To confirm urinary incontinence after radical retro-pubic prostatectomy by questionnaire and pad-test, observe the influence of radical prostatectomy on the patient's quality of life (QOL), and study the effect of urethral sphincter preservation and the patient's age on incontinence. METHODS: Questionnaire and pad-test were conducted in 165 consecutive prostate cancer patients who underwent radical prostatectomies. The mean follow-up time was 13 months (12-14 months). Each patient was kept in contact with our incontinence advisor by telephone or direct interview. At 12 months after operation, the patients were asked to the clinic to fill in the questionnaire and underwent the pad-test. In accordance to different operative techniques, the patients were divided into a sphincter repairing group (19 cases) and a sphincter preservation group (146 cases). RESULTS: All the 165 patients were kept in contact with us, underwent the pad-test and filled in the questionnaire. Of the 7 patients diagnosed as incontinence for admitting using pads, only 1 had urinary leakage, and the other 6, who did not use pads very often, showed slight change of QOL. In the pad-test, 5 patients were considered to be incontinent since the pad weight gained > 1 grams. Between the questionnaire and the pad-test there was a high concordant rate (98.8%). Within 3 months after operation, younger patients seemed to return to continence sooner. The continence rate at 12 months after operation was 99.3% in the sphincter preservation group and 94.7% in the sphincter-repairing group. The incontinence rates at the removal of the urinary catheter after operation were 60% and 82% in patients aged 51-60 and 61-70, respectively. At 3 months after operation, the incontinence rates were similar in both groups. CONCLUSION: Both the questionnaire and the pad-test are recommendable in the assessment of post-operative incontinence since it can accurately document patients' incontinent status. Preservation of the urethral sphincter and its possible innervations can improve the incontinence rate. Younger patients seem to return to continence sooner than the elders.

Development of a health-related quality of life questionnaire for Thai patients with rhinoconjunctivitis.

The objective of this study was to develop a disease-specific questionnaire for patients with rhinoconjunctivitis. All patients were recruited at the Out-Patient Clinic at Siriraj Hospital. Related topics were gathered from several sources, and a list of 63 items was produced. In phase I, the first version of the questionnaire was completed by 363 patients. Forty-eight items were identified by clinical impact analysis during the item removal process, two more questions were then added, giving a total of 50. Two hundred and forty-three patients completed the second version questionnaire in phase II. The average time taken to complete the questionnaire was 6.38 minutes. The item removal process in phase II was achieved by a multi-step process. There were 36 items in the third version questionnaire which consisted of six dimensions and two independent items as follows: symptoms (17 items), physical functioning (3 items), role limitations (3 items), sleep (3 items), social functioning (3 items), emotions (5 items), general health (1 item), and absenteeism (1 item). The scores of each item ranged from 1 to 5; a lower score indicating a better quality of life. Data from the selected 36 items was extracted to test the validity and reliability of the final version. The floor and ceiling effects of the scores for each dimension were low. Multitrait multi-item analysis was conducted to examine construct validity. The scaling success of convergent and divergent validity was 100% and 94%, respectively. Internal consistency determined by Cronbach's alpha coefficient, was satisfactory (0.79-0.87). The study indicates that the questionnaire is suitable for use in clinical settings. While the test results are encouraging, further work needs to be done on the test-retest reliability and on responsiveness.

[Development of patient satisfaction questionnaire in allergic rhinitis].

Recent suggestions emphasize the importance of assessing medical care outcomes from the point of view of both professional opinion and patient's subject like patient satisfaction as well as quality of life. Self-administered questionnaires are often used as an instrument for this purpose. When compared with quality of life, there is less useful questionnaire for patient satisfaction. Accordingly, we here aimed to develop the questionnaire, which is disease-specific, comprehensive, simple, clinically available and satisfied psychometric validation study. The items were collected from patients and satisfaction-related literature's review, and the total 20 were selected finally from them after excluding inadequate or overlapped items. Then, we conducted validation study in 214 subjects sampled randomly from 603 patients with Japanese cedar pollinosis who had visited clinics in 2003 by mailing self-administered questionnaire in spring, 2004. The response rate was 65.3%. In factor analysis, items were divided into four domains such as doctor-patient relationship, treatment outcome, geniality in hospital and convenience of medical service. The former two domains were the most correlated well with patient satisfaction. The quality of this questionnaire such as responsiveness, reliability, construct validity, convergent/discriminate validity, and clinical validity satisfied international standard. Thus, it was verified that our newly developed questionnaire is a useful and scientific tool for examination of patient satisfaction with medical care in allergic rhinitis.

Validity and recall of information from questionnaires concerning respiratory infections among schoolchildren.

The aim of the study was to assess the reliability of questionnaire information on visits to a physician and the use of antibiotics taken for respiratory infections among schoolchildren attending a water-damaged school and a reference group of schoolchildren attending an undamaged school. Two similar questionnaires on respiratory morbidity in two consecutive years were sent to the parents. The information given on the questionnaires was compared with the patient's records of the local health centre. Although the overall total numbers of ambulatory visits in the patients' records and questionnaires seemed to indicate good reliability, a more detailed individual investigation showed poor recall validity from the questionnaires, including a high percentage of unreported visits to the local health centre from both schools. Underreporting was commoner in the control school than in index school. Recall was best for the children who had no visits to a doctor. Use of antibiotics had a better recall than ambulatory visits in both schools. The study indicates that information on health services in questionnaires is not reliable, at least when occurrences in a period of one year or more are evaluated. The use of patient records as a reference of accuracy is also unreliable, unless all the health care services available to the people in the community are covered.

Measuring long-term outcome in people with lower limb amputation: cross-validation of the Italian versions of the Prosthetic Profile of the Amputee and Prosthesis Evaluation Questionnaire.

AIM: Recently 2 questionnaires have been developed for people with lower limb amputation to determine, in follow-up studies, the level of function and extent of prosthetic use, to measure major life domains connected with prosthesis function, and to study the factors potentially related to prosthetic use the Prosthetic Profile of the Amputee (PPA) and the Prosthesis Evaluation Questionnaire (PEQ). The purpose of the present study was: a) to produce Italian versions of both PPA (PPA-it) and PEQ (PEQ-it), using a validated procedure of cross-cultural translation; b) to analyse and discuss the internal consistency and construct validity of the main sections of the 2 questionnaires, in an Italian population. METHODS: The PPA questionnaire consists of 44 questions arranged in 6 sections. The PEQ is composed of 82 questions subdivided into 9 scales related to 4 sectors. In order to produce the Italian versions of the PPA and PEQ the forward/backward translation method was used. The final versions of the questionnaires were mailed to 110 patients and 95 of them returned the questionarries. RESULTS: The Cronbach's alpha of Locomotor Capabilities Index (LCI/5), part of the PPA, was 0.97, and those of the 9 PEQ-it scales ranged from 0.64 (appearance) to 0.95 (mobility, MO). The LCI/5 and MO correlated highly with each other (rs=0.81) and with the variables related to prosthesis use. There was a significant correlation among the PEQ-it domains concerning MO, prosthesis function, psycho-social aspects and well-being. CONCLUSION: Unfortunately, the acceptability and feasibility of both questionnaires (rather low completion rate, visual analogue scale format of PEQ, demanding scoring procedures) were sub-optimal, and their structure (item selection, response format, scaling properties, etc.) would need some refinement and simplification in order to facilitate a broader clinical use. On the other hand, findings for the LCI/5 (PPA) and MO (PEQ) are encouraging (particularly regarding the first scale) and confirm their sound practical and psychometric features.

Validation of EORTC quality-of-life questionnaire in Indian women with operable breast cancer.

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) module QLQ-C30 and the breast cancer-specific module BR-23 have been validated worldwide to assess the quality of life (QOL) in women with breast cancer. No such study has been published on Indian women using EORTC questionnaires. METHODS: QOL was assessed in relation to surgery, adjuvant chemotherapy, radiation therapy and hormone therapy in 299 Indian women with operable breast cancer (OBC) at the Breast Unit of Tata Memorial Hospital (TMH), Mumbai, from October 1998 to September 2001. The QLQ-C30 module was used to assess physical health, emotional, cognitive and social functioning, and the BR-23 module to assess breast cancer treatment-related symptoms. Assessment was done at 3 visits: visit 1 (after surgery); visit 2 (during adjuvant therapy) and visit 3 (on completion of adjuvant therapy). RESULTS: Of the 299 women at first visit, 274 (91.6%) completed the visit 2 questionnaire and 239 (80%) completed the visit 3 questionnaire. Only those women who filled the questionnaires at all 3 visits were included as 'valid visits' for analysis (193 of 299; 64.5%). The reliability and validity of the English and translated versions of the questionnaires were tested by Cronbach alpha (0.61-0.96) and item-scale correlation (0.63-0.93). Women with breast conservation treatment had a superior body image as compared to those with mastectomy (p <0.001). Physical, emotional and cognitive functions were not related to the type of surgery. Global QOL, physical, sexual and role functioning were found to deteriorate with chemotherapy (p < or = 0.01). Radiotherapy had only local adverse effects (p < 0.001 ), while hormone therapy had no adverse impact on QOL. CONCLUSION: QLQ-C30 and BR-23 questionnaires can be used reliably to assess QOL in Indian patients. The translated versions were found to be valid for further use in clinical trials on Indian women with breast cancer.

[The application of migraine disability assessment questionnaire (MIDAS)].

Migraine is a recurring and disabling pain disorder. The prevalence is estimated as 9.1% in Taiwan. Patients suffer from significant loss of work, time at school or ability to perform household chores, as well as other family or leisure activities. Treatment strategies during migraine attacks should be tailored based on the severity of disability. Stewart and Lipton (1999) developed the Migraine Disability Assessment Questionnaire (MIDAS) to assess the severity of disability related to migraine. This simple, self-administered, 7-item questionnaire focuses on disability in three domains (school or paid work, household chores, and family, social, or leisure activities) in the first 5 items of the questionnaire. The internal consistency, test-retest reliability, validity, ease of use, and clinical utility were all tested with good results. The questionnaire offers a simple tool to improve physician-patient communication. As for treatment strategies, a recent large-scale study done in the USA showed that it is more efficacious to treat migraine patients by adopting a strategy of stratified care based on different disability status than a stepped-care strategy. The simple questionnaire, MIDAS, has received world-wide popularity and has been translated into Japanese, Italian and Turkish. All of these versions showed good reliability and validity. Recently, one of our studies demonstrated that the Taiwan version also yielded comparable internal consistency, reliability, and validity. We hope that the MIDAS questionnaire can be widely adopted in Taiwan to help physicians assess their patients' disability related to migraine and provide clues for clinical management.

[Evaluating training programs on occupational health and safety: questionnaire development].

OBJECTIVE: To develop a questionnaire to evaluate the quality of training programs on occupational health and safety. METHODS: A questionnaire comprising five subscales and 21 items was developed. The reliability and validity of the questionnaire was tested. Final validation of the questionnaire was undertaken in 700 workers in an oil refining company. RESULTS: The Cronbach's alpha coefficients of the five subscales ranged from 0.6194 to 0.6611. The subscale-scale Pearson correlation coefficients ranged from 0.568 to 0.834 . The theta coefficients of the five subscales were greater than 0.7. The factor loadings of the five subscales in the principal component analysis ranged from 0.731 to 0.855. Use of the questionnaire in the 700 workers produced a good discriminability, with excellent, good, fair and poor comprising 22.2%, 31.2%, 32.4% and 14.1 respectively. Given the fact that 18.7% of workers had never been trained and 29.7% of workers got one-off training only, the training program scored an average of 57.2. CONCLUSION: The questionnaire is suitable to be used in evaluating the quality of training programs on occupational health and safety. The oil refining company needs to improve training for their workers on occupational health and safety.

[Reliability and validity of Burnout Questionnaire in occupational population].

OBJECTIVE: To evaluate the reliability and validity of simple Burnout Questionnaire in occupational population. METHODS: A self-administered Burnout Questionnaire comprising 19 items was developed in light of Maslash Burnout Questionnaire and used for investigating 458 employees. RESULTS: Cronbach's alpha between total items of Burnout Questionnaire and each factor fell in between 0.82 and 0.85 through the consistency test. All 19 items of Burnout Questionnaire were subjected to factor analysis, and three latent factors were identified, wherein 56.3% of total variance could be explained. According to the contents described in the items and Maslash burnout theory, they were emotional exhaustion, depersonalization, and personal accomplishment. According to the covariance and the variance analysis, there was significant difference in the integral of the type of work among the three subitems (P < 0.01); there was significant difference in the integral of depersonalization between two sexes (P < 0.01); There were significant difference in the integral of the personal achievement among different level of education (P < 0.01). CONCLUSION: The reliability and validity of Burnout Questionnaire is acceptable and can be used for assessing burnout in occupational population.

Validation of a food frequency questionnaire for Hispanics.

INTRODUCTION: The Hispanic population will grow to comprise one fourth of the U.S. population by 2050. Compared with non-Hispanic whites, Hispanics have disproportionately higher rates of obesity, diabetes, and other diet-related conditions. Valid methods for studying the dietary intake of this group are needed. METHODS: From June through September 2000, we conducted a study of low-income Hispanic men and women (n = 89) who were recruited for a validation study of the Spanish-language food frequency questionnaire used in the Study of Women's Health Across the Nation. The mean age of the participants was 36.8 years, 42% were male, and 92% had been born in Mexico. Three 24-hour dietary recalls provided the reference data. The food frequency questionnaire was administered by interview, with a portion-size graphic to aid in quantitation. The questionnaire asked about diet in the previous 12 months. Mean nutrient values, correlation coefficients, and the sensitivity and specificity for identifying people with intakes of less than the recommended levels were calculated. RESULTS: Mean energy and macronutrient intake estimates were significantly higher by the food frequency questionnaire than by the 24-hour dietary recalls. Cholesterol, saturated fat, dietary fiber, iron, vitamin A, and percentage of energy from fat were not significantly different by the two methods. The median of unadjusted correlations was 0.52 and of deattenuated correlations was 0.61. The median sensitivity was 0.62, and the median specificity was 0.76. CONCLUSION: The Study of Women's Health Across the Nation Spanish food frequency questionnaire appears to be reasonably valid in assessing the dietary intakes of Hispanics. Correlations tended to be higher than those found in other validation studies in Hispanic populations. Interviewer administration of questionnaires may be necessary in this population.

Reproducibility of a task description questionnaire for working pregnant women.

The objective of this study was to evaluate the reproducibility of a Task Description Questionnaire that was designed to investigate exposures to, and influential factors for, problematic tasks experienced by working pregnant women. The questionnaire comprised questions concerning 22 task components (covering working posture, manual material handling, work pace, prolonged postures and others), eight influential factors contributing to problematic tasks, discomfort (measured using a body map) and level of effort to perform the tasks. Reproducibility of the questionnaire was assessed by interviewing participants on two occasions one week apart for interviews at both 20 and 34 weeks of pregnancy. Eleven and 13 problematic tasks were reported by 21 working pregnant women at 20 and 34 weeks of pregnancy, respectively. These tasks were surveyed using the Task Description Questionnaire. Kappa statistics and correlation coefficients (supplemented by paired t-tests) were used to examine the reproducibility of responses to the questionnaire. The results showed that most of the variables were measured with very good or satisfactory reproducibility. The reproducibility of exposure to work posture was higher than that of exposure to manual material handling. There was no significant difference between test and retest means for the discomfort scores measured on the body map, except for the maximum discomfort score for the whole body in the 34 weeks survey. The study suggests that the questionnaire can be reliably used in the study of problematic tasks experienced by pregnant women. But an initial preview of the questions by the subjects and explanation of the questions given to the subjects by the interviewer may help to produce more reliable results.
