2. Prevention
Campaign
 Sample Recruitment
 Stratified
Random Sample
Youths
Group 1: youths
that will use the
campaign
Group 2:Youths that will
not use the campaign

3. Prevention

Control for Spuriousness
 ClinicianTraining
 Separate areas to decrease exposure to experimental
stimuli, Group 1 (control group) will be located in a
separate area than Group 2

InternalValidity
 Instrumentation – Clinician
Training
 Selection – Randomly putting
youths into Group 1 and
Group 2
ExternalValidity
 Interaction Effect (Selection
Bias) - Parents not
consenting to children being
in the campaign, so we wind
up with a specific population
that is invested in treatment.
 MultipleTreatment
Interference –Youths are not
showing up.
 Researcher Bias – How they
present the intervention.

9. Validity
Threats
Internal External
Testing- Initial interview may influence
results on final interview
Reactive Effect- Initial interview may
raise awareness of behavior and
prompt change
History- Events in individuals lives may
influence behavior during treatment
Interaction Effect – Possible that
families involved in community
centers are more eager to learn
Ambiguity Direction- Possible anger
may be influencing drinking
Reactive Setting – Hawthorne Effect-
being observed may prompt behavior
change
Instrumentation- Different practitioners
may rate drinking and anger differently
Researcher Bias – Researcher's beliefs
on drinking and anger may influence
findings
