Abstract
BACKGROUND: Public health surveys are often conducted using paper-based
questionnaires. However, many problems are associated with this method,
especially when collecting data among ethnic groups who speak a different
language from the survey interviewer. The process can be time-consuming and there
is the risk of missing important data due to incomplete surveys.
OBJECTIVE: This study was conducted as a proof-of-concept to develop a new
electronic tool for data collection, and compare it with standard paper-based
questionnaire surveys using the research setting of assessing Knowledge Attitude
and Practice (KAP) toward the Expanded Program on Immunization (EPI) among 6
ethnic groups in Chiang Rai Province, Thailand. The two data collection methods
were compared on data quality in terms of data completeness and time consumed in
collecting the information. In addition, the initiative assessed the
participants' satisfaction toward the use of a smartphone customized-language
voice-based questionnaire in terms of perceived ease of use and perceived
usefulness.
METHODS: Following a cross-over design, all study participants were interviewed
using two data collection methods after a one-week washout period. Questions in
the paper-based questionnaires in Thai language were translated to each ethnic
language by the interviewer/translator when interviewing the study participant.
The customized-language voice-based questionnaires were programmed to a
smartphone tablet in six, selectable dialect languages and used by the trained
interviewer when approaching participants.
RESULTS: The study revealed positive data quality outcomes when using the
smartphone, voice-based questionnaire survey compared with the paper-based
questionnaire survey, both in terms of data completeness and time consumed in
data collection process. Since the smartphone questionnaire survey was programmed
to ask questions in sequence, no data was missing and there were no entry errors.
Participants had positive attitudes toward answering the smartphone
questionnaire; 69% (48/70) reported they understood the questions easily, 71%
(50/70) found it convenient, and 66% (46/70) reported a reduced time in data
collection. The smartphone data collection method was acceptable by both the
interviewers and by the study participants of different ethnicities.
CONCLUSIONS: To our knowledge, this is the first study showing that the
application of specific features of mobile devices like smartphone tablets
(including dropdown choices, capturing pictures, and voiced questions) can be
successfully used for data collection. The mobile device can be effectively used
for capturing photos of secondary data and collecting primary data with
customized-language and voiced questionnaire survey. Using smartphone
questionnaires can minimize or eliminate missing data and reduce the time
consumed during the data collection process. Smartphone customized-language,
voice-based questionnaires for data collection can be an alternative and better
approach than standard translated paper-based questionnaires for public health
surveys, especially when collecting data among ethnic and hard-to-reach groups
residing in multilanguage-speaking settings.
