General Population
Drug users
Problem drug users
DRUG DEMAND INDICATORS Treatment demand Drug-related infectious diseases Drug-related deaths & mortality Police arrests (users)
… etc. …. Prevalence/incidence estimates Impact studies (costs, crime …) Targeted studies (risk groups,
drug careers, perceptions …) Surveys (extent & pattern of use in
general population, schools …)
DRUG SUPPLY INDICATORS
Drug availability (seizures, price/purity, surveys …)
Drug market studies (actors, drug flows, economics …)
International supply (trafficking arrests, production estimates ...)
Domestic Drug Supply
International Supply
Key and others core indicators
7
Drug use in general population -questions
extent and patterns of drug use? differences (by age, gender…)? sub-groups with different pattern of use? perceive availability, risks, attitudes towards drugs
and drug users? trends over time? comparable to other countries?
8
Surveys – Theory and Methodology 1
cross-sectional studies on representative sample of population
sample of respondents in given time frame
standard tools – standard questions (questionnaires)
EMQ, ESPAD questioonnaire
sampling of respondents – when standardized/comparable, allows inter-regional comparison and trends over time
quota-sampling (stratified sampling according to basic characteristics – gender, age, region, education)
9
Studies in Adult Population
EMCDDA methodology, i.e. standard questionnaire used = EMQ (European Model Questionnaire)
questions – example: cannabis
Do you personally know people who take hashish or marijuana? 1 yes2 no
Have you ever taken hashish or marijuana yourself? 1 yes2 no
At what age did you take hashish or marijuana for the first time? .........
During the last 12 months, have you taken hashish or marijuana? 1 yes2 no
During the last 30 days, have you taken hashish or marijuana?1 yes2 no
During the last 30 days, how often did you take hashish or marijuana?1 daily or almost daily2 several times a week3 at least once a week4 less than once a week
10
Data collection/interviewing PAPI: Paper And Pencil Interviewing. Data obtained from the interview is filled in on a paper
form using a pencil. CAPI: Computer Assisted Personal Interviewing. This method is very much similar to the
PAPI method, but the data is directly entered into a computer programme instead of first using paper forms.
WAPI: Web Assisted Personal Interviewing. The respondents answer the questions online, but they are also assisted online in doing so.
CASI: Computer Assisted Self Interviewing. The CASI method involves respondents taking place behind the computer themselves in order to fill in the questionnaire.
CAWI: Computer Assisted Web Interviewing. Online research in which data is obtained electronically using online questionnaires.
CATI: Computer Assisted Telephone Interviewing. The questions are usually presented to the interviewers on a computer screen, after which they ask them to the respondents.
TAPI: Tablet Assisted Personal Interviewing. This method is virtually identical to the CAPI. TASI: Tablet Assisted Self Interviewing. This method is virtually identical to the CASI. SAPI: Smartphone Assisted Personal Interviewing. With this method, the data is entered into
a smartphone by the interviewer. SASI: Smartphone Assisted Self Interviewing. With this method, the data is entered into a
smartphone by the respondent.(http://www.inviewfieldwork.com)
11
Surveys – Theory and Methodology 2 representativeness
random sampling sample size: sufficient number of respondents structure of the sample has to correspond to distribution of the
characteristic in general population – gender, age, region, education...
respondence ideally >70% (depending on study methodology) questionnaire for non-respondents (reasons)
bias on the side of researcher (e.g. insufficient reliability or validity ) on the side of respondents (e.g. does not want to answer,
response set)
13
Sample Size and Sampling Error
14
Measuring Drug Use
3 time horizons lifetime prevalence – at least once in a lifetime use in last 12 months – „recent use“ use in last 30 days – „current use“
Frequency & amount regular use: >10 times in last 30 days daily use, binge (party) consumption… problem(atic) drug use
other characteristics age at first use, route of administration… reasons for first use, context, source of drug
15
Substances Monitored Routinely
illicit drugs cannabis, ecstasy, hallucinogens (LSD), heroin and other opiates,
methamphetamine (pervitin) and amphetamines, cocaine, magic mushrooms…
licit drugs tobacco, alcohol used often as „warming-up“ questions
solvents/volatile substances
medicines on prescription (sedatives and tranquilizers) use without prescription
16

Until 2002 „Attitudes and opinions of citizens“ by Public Opinion Research Centre (PORC) non-standardised questions (experience with „illicit drugs“)
2004 the first GPS focused on drugs with use of EMQ „General Population Survey on Health Status and Lifestyle of the
Population of the Czech Republic“ by Institute of Health Information and Statistics (IHIS)
2008 and 2012 repeated GPS on drugs using (extended) EMQ General Population Survey of the Use of Psychotropic Substances
and Attitudes Towards Drug Use in the Czech Republic (2008) National survey on addictive substances use 2012 by National monitoring centre for drugs and drug addiction

GPS on drugs 2004
Survey of the Health Status and Lifestyle of the Population of the Czech Republic in 2004
The Institute for Health Information and Statistics (IHIS) in cooperation with NMC
Data collection by INRES-SONES Structured F2F, PAPI Q based on EMQ, the list of monitored psychoactive substances
was extended; closer attention was paid to pervitin, magic mushrooms and other natural hallucinogens, inhalants, and solvents
Age range 18-64 A random walk: stratified sampling by age, gender, region of
residence, and level of education Altogether 3,526 interviews were carried out (out of a total of 5,433
persons contacted). 1,766 males and 1,760 females years participated in the survey
Response rate 68.2%

GPS on drugs 2008
General Population Survey of the Use of Psychotropic Substances and Attitudes Towards Drug Use in the Czech Republic in 2008
NMC i cooperation with Centre of Addictology Data collection by INRES-SONES Age range 15-64 years, over-sampling of 15-29 years, weighted Two-stage sampling, a random walk as the last stage, quotas by
age, gender, education, region Gross sample size 5613 respondent, 4506 questionnaires collected,
i.e. response rate = 80,3% non-respondents: 1107 (aged 35-44 years), reasons: lack of time
(37%), lack of interest (31%), distrust, doubts about purpose of the study (13%) and information misuse (13%)
Questionnaire: EMQ + 3 modules, altogether >150 items Wording updated after pilot test (focus groups) and field testing 3 new modules
intensive use of cannabis (CAST) perceived availability of illicit drugs (EMCDDA) cannabis markets
30
CAST
Cannabis Abuse Screening Test 6 items enquiring whether a respondent had ever:
(1) used cannabis alone or (2) before midday (3) had memory problems as a result of cannabis use (4) been told by friends or family members to stop or reduce
their consumption of cannabis (5) tried to stop or reduce their cannabis use without success (6) had problems (at school, for example) because of their use
of cannabis When transformed and added up, all six variables constitute
the CAST scale with values ranging from 0 to 6: one point or none means a low risk 2 to 3 points imply a moderate risk 4 or more points suggest high-risk cannabis use requiring
professional intervention
31

2008: reasons for differences (1)
different formulations of questions and their context in the questionnaires (no effect – proven by subsequent survey)
varying data collection methodologies and procedures differences in the construction of samples lower degree of privacy in responding to questions in
health study lower response rate in health study sampling bias: individuals who could not be reached at
home probably more engaged in risk behaviours and may be assumed to show a higher level of drug use
the crucial role: context of questions (health versus drug)
44
2008: reasons for differences (2)
different context: personal interpretation of the question in view of the focus of research –
the respondent tends to adjust their answers according to what they think they are expected to report (for example, to lead a healthy lifestyle, to be “IN”);
the more elaborate questions asked in a monothematic drug survey – the respondent may be offered examples which help them recall their behaviour and specify what the question really means;
priming – respondents are better at recalling a topic to which they have been exposed over time;
a tendency to provide consistent responses, which may result in the underestimation of the prevalence of drug use in research concerned with health issues and, on the contrary, in the overestimation of prevalence rates in research studies focusing specifically on drugs;
social expectations which the focus of some research studies may, albeit involuntarily, arouse.
