Fear arousal and AIDS: do shock tactics work?

Area of Science:

• Public Health
• Health Psychology
• Behavioral Science

Background:

• Fear arousal is a common strategy in health education campaigns.
• Previous research indicates limited success for fear-based behavior change interventions.
• A UK government campaign on AIDS (phase 2) utilized targeted fear messages in posters and television advertisements.

Purpose of the Study:

• To evaluate the effectiveness of fear-based messages in a UK AIDS awareness campaign.
• To determine if visual (posters) or audiovisual (TV ads) formats were more impactful.
• To assess the campaign's impact on anxiety levels, attitudes, and sexual behavior.

Main Methods:

• A study involving 111 participants: 59 students and 52 individuals attending a drug-dependency unit.
• Assessed baseline anxiety levels between the two groups.
• Measured changes in anxiety, attitudes, and sexual behavior following exposure to fear-based campaign materials.

Main Results:

• The drug-dependency group exhibited significantly higher baseline anxiety than students.
• Fear messages significantly increased short-term anxiety in students but not in drug users.
• No significant differences were observed between visual and audiovisual campaign materials.
• The campaign failed to alter sexual behavior or drug-using behavior in any group.

Conclusions:

• The AIDS awareness campaign did not effectively reach its intended target group (drug users).
• While fear messages increased anxiety in students, this did not translate into behavioral change.
• Perceived personal risk and willingness to change sexual behavior remained low across all participants.
