2. VOXCO Command CenterTM has the capability for survey instruments to be presented in multiple languages. Qualified staff with fluent written and oral skills in a specific language would conduct the interviews. Multi-Language Surveys

3. VOXCO Command CenterTM has the capability for computer-assisted surveys to be completed in more than 40 languages Investigators provide to the SRSR the translated instrument Phones interviews are restricted to the languages skills represented in current interview staff The SRSR currently employs 1 bilingual interviewer, fluent in Spanish and English Additional hiring of interviewers with required language skills can occur if the needed language skill is not represented in the current SRSR staff Multi-Language Surveys: An Overview

5. Spanish English Multi-Language Surveys: Comparative View of One Question

6. Variable names and coding of responses are consistent across all language versions of a project instrument • All data regardless of language associated with the project are stored in one data table. Multi-Language Surveys: Maintaining Consistent Coding

7. At the conclusion of the interview, the interviewer returns to the questions and translates open-ended responses into English for coding Multi-Language Surveys: Translation of Open-End Responses

8. Utilizing the Extraction feature of VOXCO Command CenterTM, the SRSR can provide an investigator with datasets in a number of file formats for analyses. Presentation of Survey Data

9. Extraction of project data is set up based upon the needs of the project • Retrieval of project data can be set up on a scheduled basis with automated running of the task • The SRSR is developing protocols for providing access to investigators for retrieving extracted data from projects • Schedules for extraction of data will vary depending upon the length of the project (quick accrual of data vs. long-term projects) • A data dictionary is provided for each instrument • Variable names can be chosen by the investigator and must be no longer than 8 characters/numerals and contain no punctuation other than an underscore (_) Presentation of Survey Data: An Overview

10. Multiple data formats are available Access Command Center CSV CSVeX InterviewerSQL PNT SAV SEQ TXT XML Presentation of Survey Data: Available File Formats
