objectives of the study, screening questions, skip patterns and techniques for handling <br />potential complications. Interviewers raised questions and provide their professional <br />feedback regarding potential interviewing challenges. <br />Pre-test the Survey <br />After the questionnaire is programmed in our interviewing software system, it was <br />rigorously tested to assure all questions are asked and that data is accurately recorded <br />to deem the validity of the survey. <br />Conduct Data Collection <br />Following a successful pretest of the questionnaire, voice -interactive interviews were <br />conducted using the Ci3 CATI software, a recognized leader in computer-aided <br />interviewing. Potential respondents were contacted on weekdays at various times <br />throughout the afternoon and evening. An appointment procedure is used when <br />necessary to minimize refusals and allow respondents to complete the survey at a <br />convenient time. <br />Monitoring <br />Interviews were monitored by the data collection supervisor to ensure they are <br />properly conducted and meet the agreed-upon standards. <br />Internal Peer Review <br />HR2 Research/Analytics used an internal review process called "CERA" (create, edit, <br />review, approve) which is similar to academic peer review to ensure that each study <br />meets or exceeds rigorous quality control standards. Through this process, several <br />analysts review the statistical findings and offer critical feedback designed to increase <br />the utility of the research and produce a clear and insightful report. <br />Incidence and Response Rates <br />The incidence rate represents the percent of individuals spoken to who are qualified <br />to take the survey, meaning they spoke English and reported living within the city. <br />The response rate represents the percent of qualified individuals we spoke to who <br />agreed to participate and who completed an interview. Response rates above 50.0% <br />are higher compared to other community -wide surveys and serve to increase <br />confidence in the survey's validity and reliability. The incidence rate of the previous <br />Tukwila storm water surveys conducted by HR2 Research/Analytics was 57.22%; <br />previous response rates were at 55.83 %. <br />Use of Findings <br />HR2 Research/Analytics has made every effort to produce the highest quality <br />research product within the agreed specifications, budget and schedule.
