length of survey and response rate

A high response rate (>80%) from a small, random sample is preferable to a low response rate from a large sample. Introduction: Web-based epidemiologic surveys are being widely used, but still present lower response rates compared to traditional methods.Their design can influence survey response rates. This survey, titled the Enrolled Student Survey or the ESS, was developed in consortium with 30 other elite institutions and included over 250 individual items.

Each question type has its strengths. For online surveys, it’s important to make your survey responsive and you should limit the number of clicks needed to complete the survey. The more follow-up waves were sent and the shorter the survey length, the more likely it was to receive a completed survey, with a response rate of 21.7% for survey rounds with 3 follow-up waves, a short survey and a $2 cash incentive. Nevertheless, over the years a lot of studies have been done on what the average response rate of a survey should be and which parameters have an influence on it. The length of a questionnaire is important because it can directly affect response rates, survey costs, and data quality. We assess the association between survey layout and response rates (RRs) in the 2017 Medicare Advantage Consumer Assessment of Healthcare Providers and Systems mail survey. Counting everyone who visited this page as invited can lead to very low response rates. The tolerance for lengthier surveys was greater for surveys that were work or school related and decreased when they were customer related.

The source behind this stat also states that an internal survey receives a higher response rate than an external survey, and the rate will increase by 14% after 3-7 days after the survey was sent. Take survey completion time into consideration as you design your next survey. For in-person or phone surveys it is pretty straightforward to define who is invited to take the survey: How many people did you ask or call to participate? A variety of factors, like poor survey design, excessive survey length, and lack of interest hurt response rates (Dillman et al., 2009).

So only those respondents who entered and completed the survey will be included in this statistic. Since survey respondents have different motivations for responding to surveys, their tolerance for how long a survey is will vary. Nevertheless, in spite of these recent research studies, a higher response rate is preferable because the missing data is not random. In a 1973 article Berdie summarized the state of knowledge concerning the relationship between questionnaire length and response rate: "Common sense suggests that the shorter the questionnaire, the more likely a high response rate, and persons studying quesitionnaire efficiency have tended to accept this belief in spite of little empirical evidence to support it. A common mistake is sending the same survey to different audiences and expecting the same response rate. Therefore, non-response bias may make the measured value for the workload too low, too high, or, if they balance each other out, “right for the wrong reasons.”. However, recent studies have shown that surveys with lower response rates (near 20%) had more accurate measurements compared to surveys with higher response rates (near 60 or 70%).

So if, for example, a survey is distributed to 1000 people and 200 of them complete it, then the survey response rate would be 20%. In addition, respondents that received these invites were 2.6% less likely to drop off before completing all survey questions. In survey research, the survey response rate is the number of people who answered the survey divided by the number of people you sent the survey to (the sample), then multiply that number by 100, since it is usually expressed in the form of a percentage.
