13 Method Instrument Design The web-based survey questionnaire was developed with guidance and feedback from the Topic Panel and in conjunction with the preliminary literature review. While the survey was designed to be web based, it was also administered by email and telephone to accommodate a limited number of special requests from respondents for their convenience. These exceptions helped increase participation and respondent retention. The survey was designed to achieve maximum participation and retention, using display logic so that respondents were asked only questions relevant to them. The question blocks addressed basic information, owner and law enforcement interfaces, TSA interfaces, juris- dictional concerns, management of LEOs, cost information on the law enforcement model, LEO operations, police versus security personnel, and access to ancillary needs. Pretesting Results The survey was reviewed, pretested, and evaluated by the Topic Panel, and feedback was provided and implemented. Respondents The respondents were airport managers, airport security coordinators, and airport LEOs. Survey Administration Details The surveys were distributed electronically, with three surveys administered by email and one by telephone. These options were provided to respondents to achieve maximum participation and retention. The responses were self-reported, and independent answer verification was not conducted. The questions in the survey included quantitative (closed) questions and qualitative (open) questions; thus, the total number of responses to open questions can exceed the total number of respondents. Due to the small sample, responses are shown throughout as frequencies (or counts of responses). Data Collection Data were collected through an online survey platform, which provides immediate and secure access to all data submitted through the platform. The data were downloaded in CSV format and loaded into Excel, PowerBI, and SPSS. C H A P T E R 3
14 Models for Law Enforcement at Airports Analysis of Questionnaire The quantitative data were analyzed for descriptives and compared. The qualitative data were analyzed by using thematic coding for the respondentsâ responses. The qualitative data were reported similarly by comparing frequencies of themes or codes for each variable.
