MESS Project
An Advanced Multi-Disciplinary Facility for
Measurement and Experimentation
in the Social Sciences
Marcel Das
A brief history...
 2005: Innovation platform
Investment in Large-Scale Research
Facilities
 42 proposals, adding up to 1.5 billion
Euros
 MESS Project: one of five projects
which received funding

Core element MESS project:
LISS panel
 Online panel of 5,000 households

8,000 individuals (>= 16 years)
 Questionnaires each month, 30 min.
 Incentive 15 euro an hour (average)
4
8-6-2010
 For scientific use, at no cost
LISS panel
 Online interviews as method, but:
 Probability sample drawn from address
sampling frame of Statistics
Netherlands
 Includes households without Internet
access (less than 15%): CentERdata
provides equipment
5

 Contacted by letter, telephone or visit
simPC
Very small and silent
Only the most frequently used functions
Automatic maintenance, safety
Simple operation and readable screens
6

Installation and support
Non-response patterns
Similar to those of other leading
scientific panels
Superior to commercial access and
volunteer panels:
- no coverage problems
- no selfselection

Attention for difficult groups
 Correction by oversampling in refreshment of
2009 (with Statistics Netherlands)
8
4-4-2016
 New immigrant panel (with Cross-cultural
Psychology, Tilburg University and Statistics
Netherlands)
Respondents LISS panel:
 Get questionnaires every month
 Know: first Monday of the month
 Get also email invitation
 Can complete questionnaire at any
time during the month
Response rates: per day

Panel management system (1)
• Online system developed by CentERdata
• Easy overview of basic data (e.g.
composition household)
• Overview of all communication
12
4-4-2016
– electronic version of the exact letters that
were sent
– sent and received e-mail messages
– SMS messages
– availability of panel members (holiday,
business trips, hospital stays, etc.)
Panel management system (2)
• Issue tracking system (problems)
• Wizards to guide panel management to
update information about the household
• Tracking of devices (SimPC)
• Statistics module (response, etc.)
13

Panel management system (3)
• Automated selection processes
– via templates (standard selections)
– scheduling to open questionnaires, to
send invitations via e-mail or SMS
– possibility for entering manual selections
• Overview and management of incentive
payments

Use of the LISS panel
15

Experimental modules
 Who can use the LISS panel:
every researcher who wants to collect
data for scientific, policy or societal
relevant research
Scientific research:
Academic researchers, irrespective of
nationality, can use the LISS panel at no
cost
16
15-11-2010
 Proposals can be submitted throughout
the year
Use of a subsample
 Effects of illness babies in first year on
labour participation parents:
 Pregnant women, follow 3 years!
 Effects of the economic crisis on
household portfolio choice:
 Panel members who own stocks
 Random subsample or experimental
groups: different conditions
Biomarker data collection:




Blood cholesterol levels
Diurnal salivary cortisol
Waist circumference
Internet weighting scale
Video instruction, specially developed for
all three tests
Future: Accelerometers, blood pressure
meters
Available data
 Who can use the LISS data:
every researcher who wants to use data
for scientific, policy or societal relevant
research
 Use of data is free of charge (unless
data are used for research funded by
means of external sources)
19
15-11-2010
 Available data:
 longitudinal core study
 proposed studies
Longitudinal core study
 Household and family
 Economic situation and housing
 Work and schooling
 Social integration and leisure
 Health
 Personality
 Religion and ethnicity
 Politics and values

LISS data: archive and DDI
 Disseminated through website / data
archive: http://www.lissdata.nl
 Database is based on DDI 3: one of the
first implementations of version 3
(DDI = Data Documentation Initiative,
International XML-based standard for
data documentation)
 LISS data: complex and extensive
21
8-6-2010
 October 2011: more than 440 registered
users
Extensive data
 Example: “Do you know which panel
members are vegetarian?”
 Asked somewhere, but in which study?
 Example: “Did you ever measure
political efficacy?”
 Asked sometime, but when exactly?
 Example: “Can I estimate the housing
expenditure of impulsive persons?”
 Which items measured impulsiveness?
22

DDI 3 & LISS website:
 Search entry from Concept, Variable,
Question, Topic, and Study
 Can handle longitudinal data (waves)
 Exchangeable with data archives
 Flexibility for future applications
(Example: iPod version)
23

Current projects
 Special groups: e.g. immigrants (new
panel)
 Biomarkers: test new instruments for
measurement
 Links with administrative data (Statistics
Netherlands): substantial expansion of
research opportunities
 Time use project: smartphones
