[A comparison between three questionnaires and laboratory tests for the detection of alcoholism in general practice].

By means of a case/control study, an attempt was made to identify the different questionnaires and biological tests which might be used in the General Practice consulting room for the detection of alcoholic patients. A comparison was made between the CABE, MALT, and Skinner questionnaires, and the MCV, AST, ALT, GGT triglyceride, cholesterol, uric acid, bilirubin and glycemia biological tests. Sensitivity, specificity, predictive value and diagnostic efficiency were studied in a group of 37 confirmed alcoholics and 25 controls making up a population with a high prevalence of alcoholism. Later we analysed the changes which affect the values of the different tests when applied to a population with a low prevalence of alcoholism, in other words, the utility of the tests in general practice was evaluated. The study concludes that the diagnostic performance of the questionnaires together with case history is higher than that of biological tests in general practice, and that the routine application tests in general practice, and that the routine application of the CAGE questionnaire and to a lesser extent of the Skinner questionnaire make it possible to identify those patients suspected of alcoholism and to improve the predictive value of the biological tests applied thereafter. Nevertheless further study is necessary to confirm the diagnostic effectiveness of these questionnaires in the general population of health centre patients.

Validation of the modified Berlin questionnaire to identify patients at risk for the obstructive sleep apnoea syndrome.

BACKGROUND & OBJECTIVES: Awareness regarding obstructive sleep apnoea (OSA) among general public as well as practicing physicians is low in India. The present study was undertaken to test the utility of modified Berlin questionnaire for risk categorization of OSA in Indian setting. METHODS: The modified Berlin questionnaire was administered in 180 middle aged adults (of 320 screened), of whom, 104 underwent overnight polysomnograhy, in a cross-sectional study at a tertiary care, referral center in north India. Questionnaire addressed the presence of frequency of snoring, wake time sleepiness, fatigue, obesity and hypertension. Subjects with persistent and frequent symptoms in any two of these three domains were considered in high risk category for obstructive sleep apnoea. Overnight polysomnograhy was performed to measure apnoea and hypopnoea index (AHI). RESULTS: Questions about the symptoms demonstrated internal consistency (Cronbach alpha correlations 0.92-0.96). Of the 180 respondents to the screening questions, 80 were in the high risk and the rest were in low risk group. For 104 subjects who underwent polysomnograhy, risk grouping was useful in prediction of AHI. High risk category predicted an AHI >5 with a sensitivity of 86 per cent, specificity of 95 per cent, positive and negative predictive values of 96 and 82 per cent respectively. These results were comparable to Berlin questionnaire study done in the western population for validation. INTERPRETATION & CONCLUSION: On the basis of the findings of present study it is concluded that administration of modified Berlin questionnaire prior to a polysomnography study can identify high risk subjects and can thus avoid unnecessary polysomnography studies especially in resource-limited settings. To identify subjects at risk for OSA syndrome in general population, this questionnaire can be applied. However, the findings of the present study need to be confirmed further in a large number of subjects in a community-based setting.

[The CIS20R Questionnaire and its suitability for prolonged fatigue studies].

BACKGROUND: The aim of the study was to validate the Checklist Individual Strength (CIS20R) questionnaire for the assessment of prolonged fatigue in workers and to define its psychometric properties and fatigue standards for the population of Poland. The questionnaire contains 20 statements, scored on a seven-point scale (1-7), reflecting four aspects of fatigue: subjective feeling of fatigue, reduction of concentration, reduction of motivation, and reduction of physical activity. The outcome yielded by the questionnaire is expressed by the sum of all points scored in responding to all statements and mean values of its components. MATERIAL AND METHODS: The study was carried out in a group (325 men and 363 women) of workers employed in industrial plants, hypermarkets and municipal services; workers of research institutes (81 men and 205 women) and pregnant women (20 persons). Based on the calculated coefficients of correlation between responses to each statement and the total score, strong discriminative power of individual statements was observed. Crombach's alpha was used to assess the consistence of the questionnaire. The coefficient value for the total score was 0.912 and for the fatigue components it ranged from 0.611 to 0.879, which indicates satisfactory reliability of the method. In addition, norms were elaborated using a sten scale. The total value of 40 indicates the borderline between low and moderate and the value of 84 between medium and high level of fatigue. RESULTS: The level of the risk for chronic fatigue was estimated on the basis of investigations among industrial, trade and municipal services workers. In the group of men, the necessity of prolonged standing during work, high physical effort during work, lack of fitting to physical effort during work, and stress connected with responsibility (component of occupational stress) were the risk-increasing factors. In the group of women, they were: lack of fitting to physical effort during work, noise disturbing reasoning of speech and stress connected with psychic load and lack of social support (components of occupational stress). In both groups, sleep disturbances proved to be responsible for increasing risk of the incidence of chronic fatigue. In the group of men--the diet, and in the group of women - exercise during leisure time were found to be protective factors. CONCLUSIONS: The study revealed that the CIS20R questionnaire is a good research tool to study chronic fatigue. It was also found that the level of fatigue in the population of Poland is much higher than that in the Netherlands, the country where the questionnaire has been developed. In the Dutch studies, the value of 76 was found to be a borderline between "normal fatigue" and fatigue occurring in people with impaired health. In our studies this value corresponds with six stens, which means that it is still within the range of moderate values.

The Quality of My Life questionnaire: the minimal clinically important difference for pediatric rheumatology patients.

OBJECTIVE: To determine parent-child agreement for the Quality of My Life (QoML) questionnaire. To establish construct validity of the QoML questionnaire. To determine the minimal clinically important difference (MCID) for the Quality of Life (QOL) and Health-Related Quality of Life (HRQOL) scales. METHODS: A total of 136 families of children with inflammatory arthritis were interviewed. The QoML questionnaire was completed for the child's current state of health, and under 2 hypothetical scenarios, where (1) there is a hypothetical small improvement, and (2) there is a hypothetical small deterioration in health. The differences between the original QOL and HRQOL scores and hypothetical improvement and deterioration scores, respectively, were calculated to give MCID scores. RESULTS: In total, 131 families completed the questionnaires. Intraclass correlation coefficients for parent proxy report and patient self-report of the QOL and HRQOL were 0.63 and 0.40, respectively. Correlations of QOL with pain and disease severity were moderately negative (r = -0.55 and -0.56, respectively, p < 0.0001). Correlations of HRQOL with pain and disease severity were strongly negative (r = -0.66 and r = -0.68, respectively, p < 0.0001). The MCID for improvement on the QOL was 7 mm, and for the HRQOL 11 mm. The MCID for deterioration in QOL was -33 mm, and for HRQOL -38 mm. CONCLUSION: The QoML questionnaire demonstrated fair parent-child agreement and good convergent construct validity. MCID scores will enable clinicians to interpret QoML questionnaire results in a clinically meaningful way.

[Usefulness of a questionnaire and RAST in screening of health care workers allergic to latex].

BACKGROUND: The prevalence of latex mediated IgE allergy in health care workers varies, according to the various studies, from 0.5% to 16. 7%. The onset of latex allergy involves aspects concerning the worker's health, the need for job transfer and possible retraining. In any case, the use of latex gloves in health care environments cannot be discarded, since they offer more efficacious protection from biological agents, compared to gloves of different materials. OBJECTIVES: Our objectives were to verify the prevalence of latex allergy in a sample of 515 health care workers and evaluate the usefulness of RAST and a questionnaire especially organized to identify potentially allergic subjects, at the same time limiting the number of false positive and false negative results. METHODS: 515 health care workers of the ASUR Zone7-Ancona local health unit accepted to answer to a questionnaire and to undergo a RAST testfor latex. Those with positive responses to the questionnaire or to RAST were later invited to undergo further allergological tests (prick and prick by prick). The questionnaire was revised according to the results obtained, thus increasing its positive predictiveness. RESULTS: Prevalence of latex allergy in our sample was 1, 7%, positive predictiveness of RAST was rather low (31.3%), but increased considerably if combined with the modified questionnaire (62.5%). The Prick by Prick test gave more specific results than the Prick test. CONCLUSIONS: The proposed questionnaire can reduce the number of false positive workers needing to undergo further allergological tests and may be usefully applied in the screening of latex mediated IgE allergy in health care workers.

The validity of a food use questionnaire in assessing the nutrient intake of physically active young men.

The validity of a self-administered food use questionnaire, comprising 122 questions on food items or dishes and designed especially to assess the intake of micronutrients, was evaluated using a 7-day food record (7DR) as a reference method. The subjects kept the food record after they filled in the questionnaire. Eighty-four male athletes participated in this study. The nutrient intake from the food use questionnaires was calculated in two ways: (i) in questionnaire 1 (FUQ-1), the portion size reported by the subjects was used, and (ii) in questionnaire 2 (FUQ-2), a 'typical' portion size was used regardless of the subject's report. In FUQ-1, the reported nutrient intake tended to be overestimated in comparison to the 7DR, whereas in FUQ-2 comparable results on a group level for all nutrients, except for proteins and fats, were obtained. The percentage of subjects similarly classified into tertiles (7DR vs. FUQ-1 or FUQ-2) varied between 37 and 54 per cent. The results show that the food use questionnaire agreed well with the food record on a group level, if a typical portion size was used. However, the agreement on an individual level was not quite as good.

Validity and repeatability of the IUATLD (1984) Bronchial Symptoms Questionnaire: an international comparison.

The International Union against Tuberculosis and Lung Disease (IUATLD) Bronchial Symptoms Questionnaire (1984) was developed for use in studies of asthma and its reliability measured in an earlier survey in England. The association of the symptoms elicited by this questionnaire to bronchial response to histamine has also been described. This paper presents the results of studies of the questionnaire in four clinical centres in Europe. The reliability of the questionnaire and its ability to predict the bronchial response to histamine were compared for English, Finnish, French and German translations of the questionnaire in samples of diagnosed asthmatics and controls in Nottingham, Berlin, Helsinki and Paris. The answers to questions showed good repeatability, especially in Finland and Germany, particularly those questions on asthma and wheeze. The most sensitive symptom for predicting hyperresponsiveness was the question on wheeze, the most specific questions were those on waking at night with shortness of breath (Paris and Nottingham) and morning tightness (Helsinki and Berlin). This study shows that the IUATLD (1984) questionnaire may provide useful, valid and comparable data even in translation but these studies will need to be repeated in representative samples before such a possibility is accepted as fully demonstrated.

Twenty-four-hour recall, knowledge-attitude-practice questionnaires, and direct observations of sanitary practices: a comparative study.

Although responses to 24-hour recall and knowledge-attitude-practice questionnaires are commonly used in water-sanitation studies as surrogates for direct observation of behaviour, the validity of this approach is questionable. We therefore compared questionnaire data with those obtained by direct observation of practices related to water storage, handwashing, and defecation among 247 families in urban Dhaka, Bangladesh. Analysis of the results indicates that accord between the replies to the questionnaires and the data collected by direct observation was poor and that the responses to the two questionnaires were often contradictory. Significant disagreements between the results of questionnaires and observations arose usually because desirable practices were over-reported by the respondents. The results of the study suggest that in urban Bangladesh 24-hour recall and knowledge-attitude-practice questionnaires should not be used as proxies for direct observation of hygiene practices.

Comparison of questionnaires determining patient satisfaction with medical care.

This study compares the results of previously developed patient satisfaction questionnaires which quantitatively assessed the personal attitudes of 59 patients toward their medical care. These patients, hospitalized for acute myocardial infarction, were admitted to the intensive care unit of a community hospital in southern Ontario, Canada. The questionnaires were completed by these patients at four and six months post-myocardial infarction. This quantitative assessment of patient satisfaction, as indicated by Hulka and Ware questionnaires, provided data to compare the relative effectiveness of these questionnaires in measuring satisfaction. Generally, these questionnaires were reliable (r = .64, r = .59) and evidence of criterion concurrent validity was noted (r = .75-.81). Both questionnaires have comparable results concerning the prevalence of dissatisfaction (0-7 percent).

Angina pectoris in presumably healthy middle-aged men. Validation of two questionnaire methods in making the diagnosis of angina pectoris.

In 2014 presumably healthy men aged 40-59 yr the prevalence of previously undiagnosed angina pectoris was assessed by two angina questionnaires: (1) World Health Organization Questionnaire (WHO-Q) and (2) Greater New York Health Insurance Plan Survey Questionnaire (NY-Q). The angina prevalence given by the questionnaires singly or in combination varied between 1.15 and 4.7% (lowest prevalence by the WHO-Q interview version (WHO-Qi) and highest by the WHO-Q self-administered version and the NY-Q in combination), indicating a considerable variation in prevalence with variation in criteria used. Validation of the questionnaires by means of (1) coronary angiography, and (2) follow-up in selected cases, indicated NY-Q superiority over WHO-Q in predicting the presence of coronary heart disease (CHD). WHO-Qi had a particularly low sensitivity without being more specific. However, CHD-risk factor patterns in subgroups of individuals classified as angina-positive or -negative by the respective questionnaires were similar.

Design of a questionnaire: occupational and environmental risks for Parkinson's disease.

1. Research linking disease with occupational and environmental exposures is often predicated on obtaining accurate exposure information from affected persons. 2. Exposure history questionnaires are used to obtain comprehensive information about work history, residential history, behavioral patterns, and lifetime exposures. 3. The process of questionnaire development includes: establishing the conceptual background of the research; assuring integrity of the research questions; specifying the content domain of the questionnaire; wording, level, and formatting decisions; establishing evidence for questionnaire validity; assessment of questionnaire reliability; and final edit and polishing. 4. The careful and systematic development of an exposure history questionnaire can be a key determinant in the success of occupational health research.

[Response rate, missing values, validity and reproducibility of responses in mark-sheet and conventional questionnaires].

A self-administered questionnaire using the mark-sheet method (MSM), in which responses of subjects are computer processed directly through an optical scanning device, has recently been utilized in epidemiologic surveys. Compared to the data coding process for a conventional questionnaire, in which a keypuncher enters the responses manually into a computer (manual method; MM), optical scanning requires less time and cost. Accuracy of the MSM for use in the general population in Japan, however, remains uncertain. Therefore the response rates, frequencies of missing values, validity and reproducibility of the answers in self-administered questionnaires were compared between the MSM and MM. Subjects were 463 residents aged 40-69 years living in 6 local districts of a rural town in northeastern Japan. They were randomly allocated, by district basis, to the MSM group (n = 242) or the MM group (n = 221). The questionnaire was delivered and collected at the subject's home by volunteers. Two weeks after collecting the original questionnaire, the same type of questionnaire was again distributed to half of the responders randomly chosen to investigate reproducibility. The overall response rate did not differ in MSM and MM (96.7% vs 98.2%, p = 0.312). Among questions with a multiple-choice type of answer, proportions of missing values were not different for most of the items, but it was lower in MSM for all of the 33 food frequency items. Reproducibilities of food frequency items measured by Spearman's rank correlation did not differ substantially in two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Reproducibility of a food frequency questionnaire for use in ocular research. Eye Disease Case-Control Study Group.

PURPOSE: Assessment of nutritional factors was an ancillary component of the Eye Disease Case-Control Study sponsored by the National Eye Institute. This multicenter study was designed to evaluate the role of potential risk factors for a number of retinal disorders. The authors examined the reproducibility of the food frequency questionnaire used in this study. METHODS: A semiquantitative food frequency questionnaire, designed for use in this study, was self-administered by participants. To evaluate the reproducibility of this dietary questionnaire, a subsample of 325 participants completed a second questionnaire within 12 to 18 months of the first. Pearson product-moment coefficient was used to assess the correlation between the log of calorie-adjusted nutrient scores, and Spearman correlations were used for specific food items. RESULTS: The responses for intake of 60 food items in the questionnaire were reasonably consistent. Correlation coefficients for individual food items ranged from 0.40 to 0.82. Pearson correlation coefficients for logs of calorie-adjusted intake of nutrients ranged from 0.38 to 0.75. Nutrients of interest in eye disease include total protein (r = 0.57), total fat (r = 0.71), saturated fats (r = 0.69), carotene (r = 0.61), vitamin C (with supplements, r = 0.66), vitamin E (with supplements, r = 0.69), and zinc (with supplements, r = 0.43). Partial correlations controlling for age, sex, and clinical center were similar. CONCLUSIONS: These findings indicate that the food frequency questionnaire used in this study provides reasonably reproducible dietary information.

[Acceptability, reliability and validity of the Corney and Clare social problems questionnaire].

OBJECTIVE: To evaluate the acceptability, reliability and concurrent validity of the CORNEY and CLARE self-administered social problems questionnaire. DESIGN: Reliability was studied by a test-retest (24 hours). Validity (concordance) was studied through comparison with a standard social adaptation interview. SETTING: Primary Health Care. PATIENTS: Consecutive patients attached to a long-treatment nursing station and 4 medical clinics. MEASUREMENTS AND MAIN RESULTS: The questionnaire consisted of 33 items and evaluated 9 areas of social functioning. In each area, the items covered 2 types of evaluation: problems in objective circumstances or in functioning and level of satisfaction. There were no significant difficulties in the questionnaire's administration. In the test-retest evaluation, there was adequate concordance of the average scores of the items evaluating difficulties and problems. This was not the case for the average scores of the items which evaluated satisfaction. The validity of 28 of the questionnaire's 33 items was examined. A moderate concordance level was found for 11 items on the questionnaire. An average score taken from these items provided a sufficient measurement of tendency regarding the overall seriousness of the subjects' social problems. CONCLUSIONS: The results do not favour the use of this questionnaire as a substitute for standard interviews in the evaluation of specific social problems, but do support the use of part of it in order to obtain a valid tendency measurement.

Case finding in the elderly: a postal questionnaire.

AIMS: To evaluate a postal questionnaire designed to identify elderly persons in need of geriatric evaluation and intervention in the community. METHODS: A sample of elderly persons, over 75 years, was randomly selected from the age-sex register of four general practices in the Auckland area. All respondents filled out postal questionnaires and a blinded assessment was made in their own homes using validated geriatric assessment tools (the reference test). Objective evaluations were compared to self report questionnaire results and sensitivity, specificity, positive and negative predictive values were calculated. RESULTS: Sixty-four persons aged 75-93 were evaluated. Thirty-nine subjects (61%) answered the questionnaire in a way which indicated they had one or more unmet needs. Reference test evaluations showed that 23 persons (36%) had problems in one or more areas. Sensitivity for the questionnaire was 0.78 (18/23 correctly identified) and specificity was 0.49. Positive and negative predictive values were 46% and 80% respectively. CONCLUSIONS: A postal questionnaire may be a useful adjunct to health surveillance of the elderly in general practice in New Zealand.

Validity and reproducibility of a self-administered dietary questionnaire in obese and non-obese subjects.

The validity and reproducibility of a self-administered dietary questionnaire has been tested with specific attention to differences between obese and non-obese subjects. To test the validity, the dietary questionnaire was compared with 4-day food records, 24-h energy expenditure (24EE) and nitrogen excretion in 45 obese and 19 non-obese men and women. Energy intake was 2% higher (non-significantly) from questionnaire than from food records in the non-obese, but 35% higher (P < 0.001) in the obese. Comparing energy intake from the questionnaire with estimated 24EE, the questionnaire gave 4% higher values in both the non-obese and obese, differences which were not significant. The reproducibility in the obese sample that completed the questionnaire twice was comparable to that observed in normal populations. These data suggest that it is possible to obtain information on obese subjects' dietary intake that is at least as valid and reproducible as that from normal weight individuals.

Community-based surveillance of acute ischemic heart disease: are one-time mailed questionnaires to physicians useful?

A 12-month data collection from medical records in Seattle/King County for acute ischemic heart disease among patients with diabetes mellitus was augmented with mailed questionnaires to personal physicians. The responsible Human Subjects Committee restricted the study to a one-time questionnaire mailing. Only 380 of 1,235 patients required physician contact when information was missing from primary data sources. Questionnaires were highly personalized, and most were limited to one page. Seventy-seven per cent of 330 physicians returned at least one questionnaire, and 62% of all questionnaires were returned with usable data. We conclude that useful data may be collected from physicians by way of mailed questionnaires if researchers use a brief and personal format.

[Significance of a screening questionnaire for diagnosis of sleep apnea].

More and more patients present with nocturnal respiratory disorders, especially with sleep apnoea (SA). This makes it mandatory to develop methods for preselecting the patients. A symptom assessment questionnaire was developed according to the Marburg stepwise concept on sleep apnoea diagnostics. Every patient completes this questionnaire as a matter of routine before he is given an appointment for an examination. The procedure to be followed depends on the evaluation of this questionnaire. Questions asked: Weight, height, use of soporifics and sleeping pills, hypertension, snoring, involuntary falling asleep, respiratory standstills, tendency to fall asleep during car driving and accidents in which the tendency to fall asleep was also involved. Three categories result from the evaluation: presence of sleep apnoea improbable (negative), more accurate details of symptoms mandatory (checking required) sleep apnoea probable (positive), patient is given an appointment date. This method was tested on 124 patients (108 male, 16 female, average age 50 yrs., average body-mass index 29.1, average apnoea index (AI) 12.8) who completed the questionnaire and were examined as outpatients, independent of the evaluation of the questionnaire, using the MESAM-IV system (nocturnal long-term recording of respiratory noises, heart rate, oxygen saturation and posture sensor). Measurements according to MESAM-IV system yielded in 69 patients (55.6%) and AI < 6 (apnoea-negative). 12 patients (9.7%) had AI 6-10 (checking required), and 43 AI < 10 (positive). Basing on evaluation of the questionnaire, 42 of 43 apnoea-positive patients had been correctly classified (98%).(ABSTRACT TRUNCATED AT 250 WORDS)
