Data Collection

By employing methodologically sound procedures, PSRAI produces reliable, valid results using a variety of research technologies.  We conduct surveys by telephone, mail, personal interview and online. Through careful testing, we have developed procedures to achieve high response rates in all types of data collection. Our efficient procedures for processing data result in accurate and expeditious data delivery.

We have created innovative sample designs to facilitate surveys of hard-to-reach populations. We have extensive experience interviewing elites, both domestically and abroad, including corporate executives, government officials and influential journalists.

Our reach is global. We conduct surveys worldwide, including in the United States, Europe, South and Central America, Africa, the Middle East and Asia. We are skilled at balancing the linguistic, cultural and other structural differences among diverse countries to manage large cross-national research projects.

Many of our clients commission a combination of our quantitative and qualitative research to exploit the powers of both approaches simultaneously. We conduct focus groups and in-depth interviews worldwide.

Telephone Surveys

Interviewing by telephone remains a mainstay of the research process in the United States and around the world. PSRAI conducts more than 100,000 telephone interviews per year for our clients, with the populations ranging for the general public to former Cabinet members of the U.S. government. PSRAI is in the forefront of research on the changing landscape of telephone interviewing, whether the explosion of governmental Do Not Call lists to the growth in the number of young people whose only telephone is a cellular one. Our research helps all our clients achieve projectable, reliable results using telephone interviewing. PSRAI chooses the best telephone interviewing facility for each job. Much of our field work is conducted at our sister company, Princeton Data Source LLC in Fredericksburg, Virginia,, where highly efficient sample management procedures are integrated with high-quality interviewing skills.

Internet Surveys

For much research, data collection using the internet is often an efficient and effective method. For surveys of groups whose members are identified and have easy online access, the internet offers a new and growing mode of research. For example, for employees of a company, members of a professional association or students at a university, online surveys may be the best and most cost-effective methodology. And PSRAI research has shown than offering an online option to some respondents in such circumstances increases cooperation and speeds the completion of complex surveys. Our capabilities allow us to have a wide range of respondents and disallow any duplication of responses. 

Mail Surveys

Surveys by mail have long been a staple of PSRAI work and they continue to be a valuable tool. Mail surveys are often an excellent choice when seeking detailed information that requires the respondent to consult records – such as the accounting records of a business – to provide a completed and accurate response. We are able to provide high response rates in our mail surveys, using best practices outlined in the Tailored Design Method by Donald Dillman.  For some surveys, mailings are also valuable to stimulate higher response rates or to avoid problems cause by survey invitations that might be considered spam if sent via email.

In-person and In-depth Interviews

This is a form of qualitative research that is used for small population groups and/or sensitive topics that would allow for detailed information.  Our staff is qualified to design and conduct in-depth interviews and to report the findings of such qualitative research accurately and without bias.

Focus groups

Another form of qualitative research, this is used when formulating question for a future questionnaire, evaluate ideas, or discuss topics.  We have trained staff who work as focus group moderators. Our staff is skilled at using the results of focus groups in developing questionnaires as well as in reports and analysis that provide the depth and context from the groups.
