Background: Using a TS-ACASI to measure ADH may be a good way to overcome social desirability limits of interviewer-administered questionnaires. Varying levels of computer experience in the targeted population may affect acceptability of the TS-ACASI interviewing method.
Methods: In an ongoing RCT promoting latent TB infection treatment completion, an interviewer-administered ADH questionnaire was converted to TS-ACASI format in English and French. TS-ACASI design (voice-over tone and accent; volume, color, graphics, and layout) was appropriate to population characteristics, including literacy levels and impaired vision and hearing. Multicultural community health workers piloted TS-ACASI. Participants (pts) completed TS-ACASI ADH questionnaires at monthly follow-up visits, and an interviewer-administered acceptability interview after first TS-ACASI use.
Results: Of 71 pts, 59% were foreign born, 69% completed high school, 61% were unemployed, 44% had a history of homelessness. 21% reported ‘no computer experience’; 27% ‘a little’; 27% ‘some’; and 25% ‘a lot’. Computer experience was associated with completing high school (p<.001), being employed (p=.014), and no history of homelessness (p=.048). Pts reported that the following features made TS-ACASI experience ‘very easy’: voice-over accent (92%), speed (79%), volume (83%), overall sound (81%), and instructions (82%). TS-ACASI aspects that pts found helpful were color scheme (94%), layout (97%) and overall appearance (82%). 86% were very satisfied with the experience. Responses to acceptability questions were not associated with computer experience.
Conclusion: Appropriately-designed TS-ACASI can be used in diverse populations with varied levels of computer experience. Systems should be tailored to population characteristics and pilot tested to ensure ease of use.
