The Cardiff health survey: teaching survey methodology by participation.

Medical students were taught survey methodology by participating in all phases of a large community survey. The survey examined health beliefs, knowledge and behaviour in a sample of 5150 people drawn from the electoral register of the City of Cardiff. The study achieved several educational objectives for the medical students: they met well people in their own homes and had an opportunity to get to know a community; by taking part in a study from the initial phases to the conclusion they could appreciate the context of the theoretical teaching they were being given concurrently in their undergraduate course; they learnt to analyse raw data and produce reports; and they gained insights into the health knowledge, behaviour, attitudes and beliefs of a population. In addition, the survey produced a substantial quantity of valuable data which staff and students are analysing and intend to publish.

Methodological survey of automatic EMG analysis.

This paper describes a methodological survey of different methods, manual and computer-aided for quantitative MUP analysis up to the present. Due to different recording techniques and facilities for signal analysis individual laboratories have developed their own methods. Although most of the methods are still in the research phase, they provide a valuable contribution to clinical possibilities. The most important effect of the computer in electromyography is the fact that it emphasizes a new trend in quantitative EMG analysis also in routine clinical assessment.

AIDS survey methodology with black Americans.

Unique substantive and methodological issues are involved in conducting survey research on sexual and HIV risk related behaviors among Americans of African descent. Problem conceptualization, sampling, design of instruments, mode of data collection, interviewer/respondent characteristics, community resistance, and data analysis and interpretation are discussed. The lack of survey research on sensitive health issues is noted. Possible methods for addressing these issues are drawn from the experiences of the authors in conducting national research on the general and at risk Black community populations. It is concluded that attention to these issues can substantially improve the quality of research on AIDS related behaviors on Black communities. Finally, it is suggested that behavioral theories and sophisticated methodological and analytic approaches, sensitive to the special cultural dimensions of racial/ethnic life in the United States, would contribute substantially to the scientific armamentarium needed to successfully meet the challenge of the AIDS epidemic.

Tanzania filariasis project. Survey methodology and clinical manifestations of bancroftian filariasis.

In a Bancroftian filariasis survey on the coast of Tanzania microfilaria rates rose with age reaching 53% in the 60-69 year group followed by a slight fall above this age. The most important clinical manifestations were hydrocoele, funiculitis and elephantiasis, with hydrocoele presenting the most serious public health problem. Hydrocoele rates increased with age reaching 90% above the age of 70. The highest proportion of large hydrocoeles were also in the older age groups. A satisfactory methodology was established for the planning of future surveys leading to control.

Laboratory-based research on the Cognitive Aspects of Survey Methodology: the goals and methods of the National Center for Health Statistics study.

The National Center for Health Statistics is embarked on a major project to combine the respective strengths of cognitive psychologists and survey researchers in a common effort to improve the design of survey questionnaires. This methodological research is conducted within the framework of the National Health Interview Survey, the nation's main source of information on the health of civilians. Better quality of such information--from recall to response rates--can aid both scientific inquiry and public policy.

1988 New Zealand national immunisation survey: methodology.

In 1985 the Department of Health carried out a survey using a two stage stratified random sampling technique to select approximately 3000 children (made up of equal numbers of 5, 10 and 15 year olds). The principal aim was to provide a random sample of sera which could be used or stored for the future to evaluate the national immunisation programme and for screening of an ethical nature. The sampling frame was the 1983 list of public and private schools as provided by the Department of Education. Ninety primary schools and 50 secondary schools were identified, from which 3688 children were asked to participate. There was a 79% consent response rate. The survey largely succeeded in its objective of providing a nationally representative group of children, although the response rate was lower in 5 year olds (74%), in Pacific Islanders (67%), in children from upper socioeconomic status groups (75%), and in children who were reported not to have been immunised (56%). A similar survey is recommended every five years. In the mean time, laboratory analysis of the collected serum samples continues and results will be published separately.

Evaluation of the EPI survey methodology for estimating relative risk.

Precision in estimation of relative risks using a standardized sampling method proposed by the WHO Global Programme on AIDS was evaluated using a Monte Carlo model simulating actual populations; the proposed survey design represents a modification of the methodology used by the WHO Expanded Programme on Immunization (EPI) to estimate immunization coverage among children. This study suggests that in actual populations the proposed survey strategy is a reasonable alternative to the use of simple random sampling (SRS) at the second stage of cluster sampling. Although varying such population characteristics as the seroprevalence rate, nonresponse rate, and rate of misclassification of exposure failed to demonstrate a clear advantage of one method over the other, the added cost and difficulty of implementing SRS under field conditions warrant further consideration of the EPI-like methodology for use in estimating relative risks.

Cognitive aspects of health survey methodology: an overview.

The past 25 years have seen the development of a wide variety of sample surveys dealing with the nature and distribution of illness and disability, and with the utilization of health care services. The sample survey is currently the most widespread and influential instrument for judging the health status of the nation and for guiding health policy. The knowledge, beliefs, and attitudes of survey respondents "subjectively" affect what the survey seeks to "objectively" measure. Even as statistical sampling has been refined, so is it important to reexamine what the cognitive sciences have to offer for survey interview structure and content.

Investigating non-response bias in a survey of disablement in the community: implications for survey methodology.

STUDY OBJECTIVE: The aim was to investigate the pattern of age specific non-response bias in a two phase survey of disablement in the community. It seeks to examine patterns of response in different age groups to a household based postal questionnaire, and the implication of such trends for the estimation of prevalence of reported dependence. It also looks at the effect that the readiness to respond during the first phase postal questionnaire had on participation in the interview based second phase of the study. DESIGN AND SETTING: A two stage survey of disablement in the population was undertaken. A first phase postal questionnaire was sent to 25,168 households in Calderdale, West Yorkshire, England, to ascertain the prevalence of physical disability. The second phase comprised in depth interviews with a sample of individuals identified in the first phase as being disabled. RESPONDENTS: A total of 21,889 postal questionnaires were returned (87%) representing households containing 42,826 people aged 16 years and over. A disproportionately stratified random sample of 950 respondents reporting disability was taken for the second phase. Of these 891 were still available, and 838 (94%) were interviewed. MEASUREMENTS AND MAIN RESULTS: A study of the timing of response to a postal questionnaire showed that patterns differed for different age groups. The estimated prevalence of those aged 65 years and over who were dependent was steady over time whereas for those in the 16-64 age range the estimated prevalence fell as the survey progressed, indicating a tendency for those who were dependent to respond sooner. Examination of the relationship of responses at phase 1 and phase 2 showed that response to invitation to interview was much less in those who had responded later, and presumably more reluctantly, in the first phase. CONCLUSIONS: These findings raise questions about how different patterns of response might be indicative of bias which could differentially affect final age specific prevalence estimates. They also have methodological implications for the follow up of reluctant responders both to increase the response rate and to secure cooperation in the second phase of a two phase survey.
