Background: Asthma is the most common chronic respiratory disorder in childhood with worldwide increasing in its prevalence and global burden. The International Study of Asthma and Allergies in Childhood (ISAAC) provides a standardized methodology to describe the prevalence and severity of childhood asthma symptoms all over the world using simple standardized questionnaires that allow comparisons across geographic and linguistic boundaries. This study aimed to find a suitable application of ISAAC asthma questionnaire to improve the perception and response of the middle (preparatory) school students in Al-Sharkiya Governorate as a step to update the Egyptian prevalence of asthma among children through the translation of the ISSAC written questionnaire into Arabic and to compare the student's response to the translated questionnaire with their response to the same questionnaire after showing ISAAC videos. Results: The percentage of student's positive answers for asthma symptoms in the written questionnaire after watching ISAAC videos was significantly lower when compared to their written questionnaire answers without watching videos with no significant agreement between the student's answers in the two methods. Conclusion: Using ISAAC videos before filling the written questionnaire improved the students' understanding of and dealing with the written questionnaire.
Asthma in Iranian Schoolchildren: Comparison of ISAAC Video and Written Questionnaires
Iranian Journal of Medical Sciences, 2015
Background: The international study of asthma and allergies in childhood (ISAAC) is used to define the prevalence and severity of asthma in different regions. In this study we followed the performance of the ISAAC video and written questionnaires (VQ and WQ) to classify asthma in 13-14 yr-old schoolchildren. Methods: The present study was carried out on 3540 schoolchildren 13 to 14-yrs-old using the VQ and WQ. The students were also asked to answer a separate question if they had ever been clinically diagnosed as asthmatic. The Kappa index was used to find degree of agreement between VQ and WQ regarding asthma symptoms. The sensitivity, specificity and Youden’s index of both questionnaires were also determined. Results: The most frequent asthma symptom was wheeze after exercise in both VQ (15%) and WQ (23%). Correlations between positive responses to the corresponding questions in the VQ and WQ were significant (P<0.001). The sensitivity of both questionnaires to the question of ...
Agreement between written and video asthma symptoms questionnaires in school children in Urmia, Iran
Iranian journal of allergy, asthma, and immunology, 2007
The prevalence of asthma remains difficult to determine with precision with no absolute or gold standard for diagnosis. International Study of Asthma and Allergies in Childhood (ISAAC) developed video questionnaire for epidemiological studies with less reliance on understanding written asthma questionnaire. The aim of this research was to determine the agreement between the ISAAC written and video questionnaires (AVQ3.0) on respiratory symptoms and reported asthma. We studied 3000 children aged 13-14 years in Urmia, Iran who completed sequentially the ISAAC written and video questionnaires (AVQ3.0) at school. The agreement between responses to the two questionnaires for reported wheeze ever, current wheeze, wheeze on exercise, and nocturnal wheeze (the latter three questions relating to symptoms in the previous 12 months), and to any combination of the latter three questions was examined by using concordance and kappa coefficients as measures of agreement. The prevalence of wheeze e...

The International Study of Asthma and Allergies in Childhood (ISAAC) video questionnaire was developed to overcome the language and cultural differences in the assessment of asthma-like symptoms. 27 schools were included in the Maputo Asthma and Allergies in childhood Study (MAPAAS) using ISAAC methods, and a video questionnaire (VQ) was administered to 1614 adolescents 13-14 years old of 20 schools located in urban, suburban and semi-rural areas of Maputo (Mozambique). Simultaneously, they also replied to the ISAAC written questionnaire (WQ). According to the video questionnaire, the prevalence of current asthma was 11.9% (compared with 13.3% using the written questionnaire). Wheezing after exercise in the last year was reported by about 21%. Females reported more frequent wheezing after exercise than males (p < .001). The prevalence of nocturnal cough in the last year was 24.7%, and was more frequent in the suburban area (p < .001). "Severe attacks of asthma" was r...

Asthma epidemiology relies heavily on standardized questionnaires, but little is known about the understanding of asthma symptoms among adults in the community. In 2004, the authors assessed the level of agreement between responses to a standardized questionnaire and responses to a questionnaire completed by participants after viewing a demonstration of asthma symptoms. The study involved 601 young adults from Chile. The field-workers were trained to explain and demonstrate the asthma symptoms to the participants. The symptoms were wheeze, waking at night with breathlessness, breathlessness following exercise, and waking with cough. The kappa statistic did not exceed 0.4, and the recorded prevalence of asthma symptoms following the demonstration was 30-60% lower than that for the standardized questionnaire. Using bronchial responsiveness as the proxy gold standard, the positive likelihood ratios for wheeze and waking short of breath were higher following symptom demonstration. The low agreement between the standardized questionnaire and the postdemonstration questionnaire and the likelihood ratios' closeness to 1 for the standardized questionnaire decreases the authors' confidence in the appropriateness of this tool for estimating the prevalence of asthma in the community. For etiologic studies of asthma, it may contribute to the lack of consistency between different studies analyzing the same etiologic exposures. asthma; data collection; epidemiologic methods; questionnaires; statistics Abbreviations: ECRHS, European Community Respiratory Health Survey; FEV 1 , forced expiratory volume in 1 second; ISAAC, International Study of Asthma and Allergies in Childhood.

Objective: Asthma disease is a complex medical condition for which the control of symptoms depends on sufficient patient knowledge, self-care, and adherence to medication protocols. Researchers conducted this study to evaluate the impact of infographics and video on asthma patients' adherence to medication. Methods: A randomized clinical trial in which 80 asthmatics were enrolled and allocated to two study groups (infographic and video groups). Researchers used questionnaires to gather demographic data. A nurse assessed Morisky adherence to medication. Researchers performed data analysis using repeated measurements and Least Significant Difference (LSD) in SPSS software version 23. Results: There was no significant difference between the two study tracks (P > 0.05) in the demographic data and adherence to medication in the pretest. The differences between the two intervention groups throughout the one-month follow-up were statistically significant (P < 0.05). There were significant differences between the two intervention groups in pretest and post-test, and pretest and follow-up (P < 0.05). However, there were no significant differences between the two intervention groups in post-test and follow-up (P > 0.05). Conclusions: According to the study findings, both the infographic and video formats may have led to an increase in adherence to medication protocols among asthma patients; but it seems that the infographic format is preferred for long-term use because it does not require usage of a facility. However, education format of asthmatic people is dependent on conditions and patient preferences.
Videotape educational program for people with asthma
Canadian Medical Association journal, 1979
A videotape educational program was produced for use in adults with asthma. The program provided an overview of lung function, the physiologic abnormalities and treatment of asthma, and the approach to common problems encountered by the patients. Its benefits were examined in a randomized controlled study. The efficacy of the program in 62 patients whose mean duration of illness was 17 years was assessed by comparing the level of knowledge of the experimental group immediately after viewing the tape with that of the controls, who had not seen it; the experimental group scored significantly higher than the control group. Retention of knowledge attributed to the program was assessed after a mean interval of 16 months. The knowledge test score of the experimental group was found to have decreased to the level of the control group. The main areas in which the experimental group lost knowledge were self-care and drug therapy for asthma. The medical status of the two groups did not change...
