Overview
Introduction: iMinds-SMIT Commissioned diaries as a research tool SMIT choices Research cases Lessons learned from comparison
Commissioned diaries as research tool
Literature: Direct reporting of hard to remember data
leads to more exhaustive and accurate data Data that is not directly observable
(time/context) Open format or more structured Part of tradition of auto-collecting methods
(audio, visual)
Cases to be compared
3D-TV 2.0.
Variation in the cases
•Target population
• Online <-> offline <-> combination
• New technology or existing practices and experiences
• Format diary: event based, time based or combination
•Amount and character of questions
3D-TV 2.0.
• 18 households – 40 participants• • Event based logging of 3D sessions (video content &
gaming) + evaluation of 3D experience (scale and open questions)
• 2x diary week: TV and gaming behavior: choice online or offline
•

IM3 (Interactive Mobile Medical monitoring)
12 people with chronic heart failure Offline diary and auto-collection of pictures Intake and follow up interview 4 weeks total, 2 weeks diary Open ended & closed questions
13
Video Q-sac
Usage of video-material on different screens in the home
40 households/100 respondents Profile questionnaire and picture inventory of
multimedia Online or offline diary and follow up interview 2 years total, 1 week diary Open ended and closed questions

Tiro
ICT in the life of young people Panel study 34 participants aged 12-18 10 months Online diary sent by mail or MSN – weekly
reflection on their ICT usage

Lessons learned from comparison(Johnson & Blytheway, 2001)
1. Representation: to what extent did it put potential participants off?
2. Difficulties: were some participants unable to complete the diary due to impairments or limited skills?
3. Quality of data: how consistent, adequate and accurate was the diary as a method to record daily events and actions?
4. Influencing behavior: did keeping a diary influence behavior?
5. Online or offline
6. Ethical considerations: did the completion of the diary cause some undue distress, anxiety or inconvenience?
18
Representation: burden of the auto-collective method
No difference in experienced burden offline <-> online (exception: double entries)
Limited amount of clear questions (example answers) Type of information? Written down (structured) or called in
(experiences)
Video-Q sac: confronting media behavior 3D-TV: 3D as ‘event’ TIRO: reporting on repetitive behavior
19
Difficulties with filling in the diaries: impairment and skill Online: tablet/computer access and skill Camera: instructions Elderly: writing culture versus visual, physical
impairment Ehealth projects:
stress factor
20
Quality of the data:consistency, adequacy, accuracy
Quantitative information: logging Diary: qualitative data; representations Open ended questions depends on willingness
of respondent Importance of opening question: average day? Necessity of follow up interview
21
Influencing behavior Social desirability bias
Future behavior: e.g. Watch less tv
Higher usage pattern in order to be ‘good user/participant’
Ehealth research and compliance to social standard of ‘good patient’
22
Ethical considerations: stress, anxiety and inconvenience
Open research role – inform when recruiting - trust
Informed consent
Stressful life events and data collection: e.g. IM3
23
Online or offline Participants:
Preference for offline Nice lay-out/object as incentive Provides opportunity for additional remarks more easily Easy to take: size matters Time - availability Dependent upon normal everyday ICT use (online already –
switching between devices?) Researchers:
Number of participants influences choice Online: data is already digital Offline: additional comments – easy to take to interview Alternatives: call-in, video reporting, …
