Abstract
Problem Statement: Although direct-to-consumer advertising (DTCA) of prescription drugs is banned in Thailand, it recently
became a global phenomenon largely because of advances in information technology. Proponents suggest that DTCA educates
consumers about diseases and treatment. Opponents argue that DTCA misleads consumers and causes irrational drug use.
Understanding the effects of DTCA can assist policy makers in making informed, appropriate decisions on this issue.
Objective: To determine how DTCA motivates consumers, based on self-regulatory focus and self-construal orientation. Selfregulatory focus posits that behavior is regulated by two systems: promotion (emphasizing achievements) and prevention
(emphasizing safety/obligations). Self-construal orientation suggests that behavior is guided by two self-views: independent self
(emphasizing self-fulfillment/uniqueness) and interdependent self (emphasizing family/social relationships). The independent self
emphasizes self-fulfillment and therefore is compatible with a focus on promotion. The interdependent self emphasizes maintaining
relationships and avoiding mistakes, and therefore is consistent with a focus on prevention. We hypothesized that goal-compatible
ads will lead to more favorable attitudes toward the ad and the brand advertised, greater intention to act and greater likelihood of
action, and more perceived benefits and fewer perceived risks of the product. We also hypothesized that prevention ads will elicit
better recall of risk information, more negative emotions, and fewer positive emotions than promotion ads.
Design: A 2 (independence vs. interdependence) × 2 (promotion vs. prevention) factorial design was used.
Setting and Study Population: A random sample of 220 females aged 40 years or older, who work at a large university but are not
faculty members or healthcare professionals/practitioners, were randomly assigned to view one of the four mock ads for an antihyperlipidemia drug and complete a questionnaire.
Outcome Measures: Main outcome measures included attitude toward the ad and the brand advertised, intention to act, likelihood
of action, perceived benefits and risks of the drug, emotional response, and recall of risk information. Data were analyzed with
ANOVA and ANCOVA.
Results: Results partially supported the hypotheses regarding goal-compatibility and emotional responses to the ad. Surprisingly,
results for recall of risk information were opposite to those hypothesized. Subgroup analysis showed that individuals with a positive
or neutral attitude toward DTCA reacted to ads consistently with our predictions, whereas those with a negative attitude toward
DTCA reacted to the same message in the opposite way to what we predicted.
Conclusions: The motivational themes in DTCA affect consumer behavior. The impact is a function of the interaction between the
themes and the pre-existing attitudes of consumers.

Introduction
• Direct-to-Consumer Advertising of Prescription Drugs (DTCA)
– First introduced in UK and USA in the early of 1980s
– 3 types: Product specific ads (brand name + indication +“risk information as fairbalance regulation”), Help-seeking ads (indication w/o brand name), Reminder ads
(brand name w/o indication)
– Recently, help-seeking ads of Rx drugs were found in Thai consumer magazines.
• Effects of DTCA
Positive effects
Negative effects
Create informed consumers
Create consumers’ demand
• Educate or inform consumers
• Misinform or mislead consumers
• Increase discussion and MD-Pt relationship • Create tension on MD-Pt relationship
• Improve consumer health
• Jeopardize consumer health
• Goal of study: To investigate the effects of the motivational themes in
DTCA on consumers’ attitudes, perception of drug’ risks/benefits, ability
to recall of risk information, intention-to-act, and likelihood-of-action.

Study framework
Theories
Goal Compatibility
Self-regulatory
Promotion focus
focus theory
• Goal is to achieve positive
outcomes
• Sensitive to presence/absence
of positive outcome
• Focus on accomplishment
Prevention focus
• Goal is to avoid negative
outcomes
• Sensitive to presence/absence of
negative outcome
• Focus on safety & obligation
Self-construal
orientation
Interdependent self
• Goal is to achieve group benefits
(collective goals)
• Focus on connectedness, comply
to duties, maintain harmonious
relationship, avoid conflicts
Independent self
• Goal is to achieve personal
benefits (personal goals)
• Focus on separateness, selfreliance, self-fulfillment
Goal compatibility occurs when:
 Promotion focus is combined with the independent self
 Prevention focus is combined with the interdependent self

H 1 – 6: Ads with goal compatibility will elicit 1) more favorable ad attitude, 2) more
positive brand attitude, 3) greater intention-to-act, 4) greater likelihood-of-action,
5) higher perceived drug’s benefits, and 6) lower perceived drug’s risks.

H 8b:
Prevention focused ads will elicit better recall of risk information.
Promotion focused ads will elicit more positive emotional responses to the ad.
Prevention focused ads will elicit more negative emotional responses to the ad.

Discussions
• H1 – 6: Opposite patterns between positive/neutral
vs. negative attitude groups
• Advertising acceptance – rejection assumption
• Acceptance – external message conforms to pre-existing attitude
• Rejection – external message differ from pre-existing attitude
• H 7: Promotion focused ad is better in eliciting risk
information recall than prevention focused ad.
• Differences in strategic means: Approach vs. Avoidance
• The role of positive emotions on cognitive function (H8)
• The role of attention

Conclusions, Limitations &
Public policy implications
•
Conclusions
–
–
•
The motivational power of the ads depend on ads’ and consumers’ characteristics.
Self-regulatory focus as well as self-construal orientation proved to be a useful
framework in understanding the mechanism of how DTCA influence consumer
behavior.
Limitations
–
–
–
–
•
Results may not be generalized to male or general populations
Study design is based on “forced exposure.”
Choice of product is limited to only cholesterol-lowering drugs
Choice of media is limited to print media only
Public policy implications
–
–
It is important for public policy makers to understand the role of pre-existing
attitude toward DTCA in persuasion
They also need to take the role of motivational themes in risk information recall in
to consideration for drug advertising regulations.
