  4. 4. 1 7 tips for successful questionnaire design www.dhpresearch.comUNDERSTAND THE BIG PICTURE ExamplesIt is essential that the overall objectives of the patient survey are If the objectives of the survey questionnaire are, fordefined at the outset (the research question). This will include example, to gain an insight into the health status ofestablishing the purpose of the survey e.g. measuring patient homeless people, then a self-completion or telephonesatisfaction, experience and outcomes, clarifying the target administered questionnaire is not feasible. If, however,population the questionnaire will be administered to e.g. patient we wanted to find out the level of patient satisfaction ofgroup, disease type, how the information will be collected e.g. a sample of patients registered with a general practicepaper/pencil, interview, web and how that information will be used using a five-item questionnaire, this could be carried oute.g. improve patient experience. using either a self completion or a telephone interview. Availability of resources include costs, personnel to conduct interviews or handle administrative tasks, skill and time to develop and administer the questionnaire, data coding and entry, data analysis. Characteristics of the target population include their overall educational level and the accessibility to the respondents. If the potential respondents are geographically widely dispersed then face-to-face interviewing will be impractical. Copyright DHP Research 2012

Reliability refers to howpatient satisfaction or experiences of the different touch points of well data collected by using a questionnaire can be reproduced ofthe patient’s journey, access to treatment etc. which the more common indicator of reliability is test-retest reliability.Tailoring the content to meet the objectives of the patient surveyideally includes both a comprehensive review of the literature and Validity is how well the questionnaire measures what it is intendedthe undertaking of a small-scale qualitative study to identify the to measure. For a measure to be valid it must be reliable, butrange of behaviours, attitudes and issues relevant to the objectives remember something can be reliable without being valid.of the survey.

These should the overallbe listed and decisions made on how they can be measured. structure of theFrom this, the detailed design work can start, such as formulating questionnaire canthe specific questions, deciding on the sequence of questioning and be developed”listing answer categories, adding instructions, and signposts andquestion skip instructions if its an interview administeredquestionnaire.

  8. 8. 5 7 tips for successful questionnaire design www.dhpresearch.comCRAFT A GOOD QUESTION Aspects of good word craftingThe principle aim in writing a survey question is to ensure • Use simple language, avoid the use of technical terms, professional jargon and abbreviationsthat it means the same to all the respondents, who shouldbe able to respond with as accurate a response as possible. • Avoid words that may have more than one meaning (e.g. dinner)This will include for example: using simple language, • Avoid questions that are not sufficiently specific (e.g. How well do you manage your diabetes?)avoiding the use of technical terms and abbreviations aswell as only ask questions that are relevant to the • Avoid ambiguity (e.g. What kind of day has it been for you?)respondent. • Keep the maximum number of words in a question to approximately 20 • Avoid double-barrelled questions (e.g. How do you feel about the treatment you haveA number of factors that need to be addressed when been receiving for your present illness, and the doctors who are treating you?)designing patient survey questions include: • Avoid double negatives – a negative statement followed by a disagree response (e.g. I feel there is no one I’m close to – disagree).Memory Avoid over-taxing the respondent’s memory • Avoid leading questions (e.g. Many patients now days think that waiting are too long. Do you?)Motivation Ask questions that are relevant to the • Avoid the use of loaded words and concepts (e.g. those which are emotionally coloured and suggest a feeling of approval or disapproval)respondent • Avoid the use of presuming questions (e.g. How long did you have to wait the last time you visited your local accident and emergency department?)Communication Ensure what we are asking the respondentis clearly communicated Copyright DHP Research 2012
