Research Methods
How do we know about drug use/abuse trends?
o Research
Why is it important to know the different methods for conducting research?
o Different methods ask different questions and yield different answers
Human-Based Research
Case studies
o Interview-based, lack of scientific controls (no “normal” comparison)
o Biased by population Ex) Rehab center
*some flaws to this method
Naturalistic Observation
o Observation based, lack of controls
o What is real behavior and what is based on the viewer’s interpretation?
Flaws to this method because the interpretation can be wrong
Laboratory Studies
o Limited by recruitment pool Ex) College students
o Lack of controls (depends on the study)
MRI – Magnetic Resonance Imaging
Studies brain anatomy
fMRI – Functional Magnetic Resonance Imaging
Studies brain function
Surveys
o Self-Reports, includes clinical populations and general populations
o Issues?
How do differences between patients and non-patients affect the
information provided?
What about denial and lying?
o Maximizing accuracy in surveys (reliability and validity)
Written assurance of confidentiality
Setting that encourages honesty
Drug free state (participants are sober)
Clearly worded, objective questions (no subjectivity)
Memory aids Ex) TLFB – Alcohol Timeline Followback
Giving someone a calendar and have them point out which days
they remember drinking instead of asking them how many days
they drank in the past month
o General Population Surveys
Are they accurate?
