Conducting Surveys, Including Questionnaire Design

A survey is a report design that collects the same data on each case in the sample. This produces a standard fix of data for each bailiwick that can be analysed statistically to look for patterns and relationships between the variables assessed. Examples include big national household surveys, such as the Health Survey for England, as well equally smaller surveys, for instance asking hospital patients near their experiences. Surveys can be used to assemble information on a range of topics relevant to healthcare, such as wellness behaviours and public attitudes.

If well designed, with a big enough representative sample, surveys can generate useful generalisable data which can generate hypotheses for further research. However, surveys cannot answer questions nigh causation.ⁱ

Steps in Designing and Conducting a Survey ²

In that location are several steps which should be considered when designing a survey:

ane. Institute the goals of the project - what exercise y'all desire to learn? This will decide who you survey and what you will ask them.

2, Determine your sample – different sampling methods are covered elsewhere ("Methods of sampling from a population"). However, in that location are two master components to choosing a sample:

Who are you target population?
How many people will you interview? This may involve a trade-off between the benefits of a large sample versus the costs of interviewing a large number of people

3. Choose interview methodology – determining the method of data collection. Possible methods include:

Personal contiguous interviews
Telephone surveys
Mail surveys
Cyberspace surveys

4. Design your survey – this is addressed in the subheading Questionnaire Blueprint, below.

five. Airplane pilot the questionnaire with the target group – this may reveal unanticipated issues with layout, question wording, instructions, etc. It also tests whether the questionnaire tin can be administered in a reasonable amount of time and helps to rephrase or re-structure questions, for instance if the range of responses is inadequate. Information technology may likewise be of import to determine whether the questionnaire is culturally acceptable to written report participants, likewise as whether information technology generates reliable and consistent answers.

6. Conduct interviews and enter data

7. Analyze the data and write the report

Survey documentation

The principal documentation in a survey is the questionnaire itself, or the paperwork used to tape subjects' responses. Nonetheless the document linked hither, describing the Malaria Indicator Survey³ carried out by the World Wellness Arrangement and other groups, illustrates the range of other documents that tin can be produced to accompany a survey.

This includes the questionnaires used with participants, but also manuals for both the interviewers and their supervisors, other documentation for preparation, and guidelines for sampling. Consequently, the methods are transparent and could exist replicated by other investigators. However, more chiefly, it helps to ensure that the methods used are rigorous and there is minimal variation in the techniques used by dissimilar interviewers.

Questionnaire design

Questionnaires may be used every bit the sole instrument for the collection of survey data, or in combination with other instruments of data collection. The degree to which a questionnaire produces data that is relevant and valid to a study'southward goals and objectives will depend on how well the questionnaire is designed, how well the questions are constructed and how well it is administered.

A valid questionnaire measures what it claims to mensurate. For example, a self-completed questionnaire that seeks to measure nutrient intake may be invalid considering it measures what participants say they take eaten, not what they have actually eaten.^iv Careful consideration of the aims and objectives of the study is crucial if the questionnaire is to yield responses that are both valid and reliable.

Perhaps the nearly of import guidance at the pattern stage is 'Osculation' ("keep it short and simple"). If you lot present a xx-folio questionnaire about potential respondents volition give up in horror earlier even starting.²

Overall design ¹

The language used in a questionnaire should exist clear and simple, with short sentences. Abbreviations and jargon should be avoided, and the language should be appropriate for the target audience. Professional production methods volition also convey the impression that the questionnaire is important.

The questionnaire should offset with non-threatening, interesting items, and ideally the almost of import questions should be included in the first half every bit respondents may return incomplete questionnaires. Questions should exist grouped in coherent categories, leaving sufficient infinite for responses, and the questionnaire should exist easy to navigate.

The question format should be varied to prevent participants producing repetitive answers as their attention wanes (known as habituation).

Types of question

The first task when generating questions is to cull the variables you want to measure. This may be done purely theoretically, for example, covering the bug you think are of import, past using a focus grouping or interviews to determine what is of import to the target grouping, or past identifying important variables via a literature search. Questions may generate either numerical answers, which can exist analysed quantitatively, or text-based examples, which may require a qualitative style of assay.

There are two main types of question: ⁴

Closed questions limit the response to a specified list of possible answers. This may either be 'Yes/No' or a multiple choice format. This has a number of advantages for the researcher, including providing a set of standard responses that enable researchers to produce aggregated data quickly. However, the richness of potential responses is limited.⁴ Closed questions may likewise fail to include all potential responses, leading to biased results. Where advisable, closed questions should also include an open-ended question following 'Other' or 'Don't Know' responses.
Open up questions allow the respondent to answer freely. Nonetheless, if open-concluded questions are used, the methods for analysing these responses is more complex.⁴

Participants may too be asked to marking their reply on a rating or agreement scale. Qualitative written report designs, which may involve a more in-depth interview with participants, are discussed in elsewhere syllabus (see Section 1D - "The principles of qualitative methods").

Maximising response rates

In order to produce results that are representative, it is important to aim for the highest response rate possible. Potential barriers to participant accuracy and honesty include:¹

Excess mental demands – for example, difficulty understanding the question, difficulty in recalling moods and events over time
Biases in answering the question – for example, social desirability (seeking to present oneself in the best light), recall bias, or end avoidance (respondents choosing not to give extreme answers on a continuous scale).

Other tips to better response rates include:

Notifying participants in advance with a letter of introduction outlining the purpose of the study
Using a clear and simple layout
Using clear and concise questions which avoid the use of technical jargon, and long, leading or negative questions
Inclusion of a stamped addressed envelope if conducting a postal survey, or collection of questionnaires if feasible
Ensuring anonymity where possible, especially if the questionnaire includes sensitive items
Follow-upwardly of non-responders by telephone or letter
Rewards for completing the questionnaire, such as a free gift or donation to charity

Assessing the Validity of Observational Techniques

Validity

The validity of an instrument is the extent to which it measures what it is intended to measure.

Streiner and Norman describe validation equally a process of hypothesis testing: "Someone who scores highly on this measure will also do well in state of affairs A, perform poorly on test B, and will differ from those who score poorly on the scale for traits C and D."^vi

More than detail on the types of validity tin can exist found in the chapter "Validity, reliability and generalisability".

Assessing the validity of observational techniques

Observational techniques involve measuring phenomena in their natural setting. In practice, in that location are ii wide approaches for assessing validity:

A test may be compared with the all-time available clinical assessment. For instance, a self-administered psychiatric questionnaire may exist compared with the majority opinion of an expert psychiatric panel.
Alternatively, a test may be validated by its ability to predict another relevant finding or event, such as the ability of glycosuria (glucose in the urine) to predict an aberrant glucose tolerance exam, or of a questionnaire to predict future disease.

Subjects are classified as positive or negative for the outcome, first on the basis of the survey or new instrument, and and so co-ordinate to the reference test. The findings can then be expressed in a 2x2 contingency table.

From this table several important statistics tin can be derived.

Sensitivity (a/a+c) - a sensitive examination detects a high proportion of the true cases
Specificity (d/b+d) - a specific exam has few fake-positives
Systematic error (a+b)/(a+c) - the ratio of the total numbers positive from the new examination compared with the reference tests. This indicates the proportion of counts that were correct.
Positive predictive value - the proportion of examination positives that are truly positive.

These statistics are addressed in more detail in Section 2C ("Diagnosis and Screening").

The validity of observational techniques can be improved in diverse ways:

Grooming observers and consider the setting of ascertainment
Ensure an advisable and representative sample, and consider the effect of reflexivity (the effect of observation and the observer on participants)
Ensure the results of observations are accurately recorded, for case by having ii observers, or by recording spoken responses
Triangulate responses by repeating observations, or past assessing the result of involvement with additional instruments
