In the fifth season of The Simpsons, the family is watching a video from self-help guru Brad Goodman, who suggests that his program can cure a long list of ailments, including “Depression, Insomnia, Motor-Mouth, Darting Eyes, Indecisiveness, Decisiveness, Uncontrollable Falling Down, and Geriatric Profanity Disorder (GPD).” The list is vintage Simpsons, yet it reveals some very real problems that market researchers often see when reviewing client-written questionnaires.
One of the most common problems we see with questionnaires is excessively long lists. The above list is mild compared to some. Clients often have a limited budget and a long list of attributes, products, etc., that they want to test in their research project, and thus they try to cram all of it into one survey. Bad idea.
The average survey respondent does not regularly take surveys, and a long list can be overwhelming. Think of the forms you fill out when you go to the doctor; there is invariably a long list of medical conditions you need to report. It’s the same with market research survey, only your life doesn’t hang in the balance. It is simply unreasonable to expect a respondent to give up their personal time to read through a list that is, in all likelihood, much longer than it needs to be.
And when is a list too long? There is no definitive answer, but if there are twenty items on a list, it is safe to assume that some of the least popular options will garner only one or two percent of the vote. What does that really tell you that you didn’t already know? As an association executive, you probably already knew that those were some of the least popular or most underperforming options. Your goal is to learn which options are in the top three (or four, or five).
The other problem exemplified in the list from The Simpsons is confliction response options. “Indecisiveness” and “decisiveness” are presented as options from which the same person could suffer. Yes, anything is possible, but it is also not likely. We see this in questionnaires all too often. When someone selects conflicting answers, researchers only guess what the respondent meant.
Part of the craft of writing a good questionnaire is to engage the respondent and not to lead them into situations where they can mistakenly report incorrect or conflicting data.
These are just some of the pitfalls that the Institute for Association and Nonprofit Research (IFANR) can help you to avoid when writing a questionnaire.
