This study identified three distinct segments of young adults in Queensland based on sexual health behaviors. Demographic and behavioral factors were key to defining these groups for targeted interventions.
Area of Science:
- Social marketing
- Public health
- Behavioral science
Background:
- Segmentation is crucial in social marketing but often underreported.
- Limited research exists on segmentation for young adult sexual health in Queensland.
Purpose of the Study:
- To extend segmentation research by applying all four bases.
- To examine young adults' (15-29) sexual health behavior in Queensland.
Main Methods:
- Online survey conducted with 15-29 year olds in Queensland, Australia.
- Data collected online and in-person on university campuses.
- Quotas used to ensure demographic representation.
Main Results:
- Two-step cluster analysis identified three distinct segments.
- Key segmentation variables included age, household type, risky sexual encounters, and STI testing history.
- Demographic and behavioral variables proved most effective for segment definition.
Conclusions:
- Three distinct segments were identified among young people aged 15-29 in Queensland.
- Behavioral variables are critical for understanding and segmenting sexual health contexts.
- Findings provide insights for targeted sexual health strategies.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
