In our earlier article, Jim Lewis and I reviewed the published literature on labeling scales. Despite some recommendations and “best practice” wisdom, we didn’t find that fully labeled scales were measurably superior to partially labeled scales across the 17 published studies that we read. In reviewing the studies in more detail, we found many had confounding effects when comparing between full labeling and partial labeling—meaning

Each January millions of people make New Year’s resolutions. One of the most popular is to lose weight and stay in shape. Gyms get packed each January, then around Valentine’s Day the “resolutionary” crowds tend to fade away. It’s not easy to change habits but several websites try to help you build the right fitness habits throughout the year. It can be hard enough to

To have a reliable and valid response scale, people need to understand what they’re responding to. A poorly worded question, an unclear response item, or an inadequate response scale can create additional error in measurement. Worse yet, the error may be systematic rather than random, so it would result in unmodeled bias rather than just increased measurement variability. Rating scales have many forms, with variations

We’ve written extensively about the System Usability Scale (SUS). It’s the most widely used and cited questionnaire for measuring the perception of the user experience. But likely the second most widely used and cited questionnaire, with over 2,000 citations, is the Post Study System Usability Questionnaire (PSSUQ). It also goes by the name of Computer System Usability Questionnaire (CSUQ). MeasuringU Press is proud to have

Question wording in a survey can impact responses. That shouldn’t be much of a surprise. Ask a different question and you’ll get a different answer. But just how different the response ends up being depends on how a question has changed. Subtle differences can have big impacts; alternatively, large differences can have little impact. It’s hard to predict the type and size of impact on

Over half of U.S. households have a pet. And for many people, they are more than pets; they are family. But pets are also a big business. It’s estimated that pet related products and services account for $70BB annually in the U.S. alone. And a lot of that spending happens online. To better understand the pet website user experience, we conducted two studies. The first

In an earlier article, we reviewed five competing models of delight. The models differed in their details, but most shared the general idea that delight is composed of an unexpected positive experience. Or, for the most part, delight is a pleasant surprise. However, there is disagreement on whether you actually need surprise to be delighted. And if you don’t need surprise, then delight is really

Small changes can have big impacts on rating scales. But to really know what the effects are, you need to test. Labels, number of points, colors, and item wording differences can often have unexpected effects on survey responses. In an earlier analysis, we compared the effects of using a three-point recommend item compared to an eleven-point recommend item. In that study, we showed how a

To have loyal customers you need satisfied customers. But is satisfaction enough to gain loyalty? Some argue that you need more than satisfaction. You need to consistently exceed expectations and delight your customers to generate loyalty. However, others have argued that instead of worrying about delighting customers, minimizing the effort customers need to expend to do business with you will lead to loyalty. And meeting
