The traditional Likert scale<\/a> \u2014where survey participants specify their level of agreement with a statement (i.e., agree strongly, agree, neither agree nor disagree, disagree, disagree strongly)\u2014is the most widely used scale in survey research<\/a>. But does it provide the most accurate answers? And are there more engaging survey measures available?<\/p>\n

Some experts believe the Likert scale is a rather imprecise instrument. A participant\u2019s true opinion can lie in the spaces between the allowable answers and even beyond the traditional end points. Some suggest other scales may be better at enabling survey respondents to differentiate their opinions.<\/p>\n

Adobe Flash, now widely adopted, gives researchers the opportunity to produce question and answer styles that incorporate a greater breadth of answers, as well as enable animation and interactivity. One such measure is the Slider. Sliders look engaging and offer a degree of interactivity beyond merely answering questions.<\/p>\n

In an effort to determine how this Flash-based alternative compares to the standard 5-point Likert scale in terms of data collected, level of respondent engagement and respondent satisfaction with the instrument, Survey Sampling International (SSI)<\/a> recently undertook a research experiment. The results are available in a new White Paper titled \u201cSlider Scales in Online Surveys.\u201d<\/em><\/p>\n

SSI\u2019s experiment dealt with two questions about the Likert scale:<\/p>\n

    \n
  1. Equivalency of ratings:<\/strong> If item A is rated \u201cagree slightly\u201d and item B is also rated \u201cagree slightly\u201d does the respondent agree to both items to the same degree? Is the Likert Scale too blunt an instrument to detect the subtle differences between items? <\/em><\/li>\n
  2. The spaces between:<\/strong> Is there some level of agreement between \u201cagree slightly\u201d and \u201cagree strongly?\u201d Is there some level of agreement below \u201cagree slightly?\u201d Do we force people to state something that is not their true opinion because we offer too few alternatives?<\/em><\/li>\n<\/ol>\n

    In SSI\u2019s experiment, a random subset of respondents was presented with a 5-point Likert scale and four statements. After completing the exercise, respondents were asked to what extent the instrument allowed them to accurately give their opinions. Subsequently, respondents were presented with the items again and offered the opportunity to re-score each item using 5 points above or below the original stated answer. Interestingly, with this expanded scale, a large number of people elected to change several of their ratings.<\/p>\n

    From SSI\u2019s results, it is clear that survey participants have a finer definition of agree and disagree than the Likert scale allows. The Slider allows researchers to collect a greater granularity of detail than they can with the Likert scale. Furthermore, respondents who used the Slider scale reported higher levels of satisfaction with this instrument as a means of capturing their true opinions.<\/p>\n

    In today\u2019s sampling environment, researchers are increasingly vying for respondents\u2019 attention, and data integrity is a constant concern. A move toward more engaging and interactive question and answer formats can help address these issues. Sliders are one Flash-based alternative to traditional Likert scales that is well worth considering.<\/p>\n
