Feasibility is being measured by the rate of recruitment, representativeness of the study sample, and retention rates.
In Netherlands-population, the sample contacted through the internet was representative but the study was stopped when only 1.2% had answered; the denominator (the number who had an opportunity to respond within the 4 days) was unknowable and, therefore, so are the responder-rates and degree of representativeness.
With respect to generalizability, despite a response rate of 39%, the representativeness survey suggests that HCWs who participated were similar to nonparticipants.
While the main concern is that recruits should be fully informed and free to make their choice, all researchers are conscious of the effect of a low recruitment rate on the representativeness of the sample obtained 1 2 and thus the generalisability of findings.
Confidential sampling via the Registry of Births, Deaths and Marriages meant we were unable to send tailored reminders to non-responders to encourage survey completion, or obtain further data determining the precise impact of the response rate on the representativeness of the sample.
The quality of data collected in survey research is usually indicated by the response rate; the representativeness of the sample, and; the rate of completed questions (item-response).
Still the quality of data collected in survey research is often indicated by the response rate; the representativeness of the sample, and; the rate of completed questions (item-response).
For example, pilots on hard-to-reach groups or reluctant participants may have low response rates; however, the addition of these participants could improve both the overall response rate and representativeness of the study population.
Paper quality was determined by the presence or absence of study characteristics of: reliable data collection, adequate response rate, representativeness of participants, completeness of results, methodological limitations, and honest and objective conclusions.
Only a very high participation rate guarantees representativeness of the participating sample.
Second, given the low PCP response rate, the representativeness of the sample cannot be firmly established.
