Applying the transtheoretical model to cancer screening behavior

Area of Science:

• Health Behavior Change
• Cancer Prevention and Control

Background:

• The transtheoretical model (TTM) is a widely used framework for understanding health behavior change.
• Its application to cancer screening behaviors, particularly mammography, has been explored in various studies.

Purpose of the Study:

• To comprehensively review published research on the application of the transtheoretical model (TTM) to cancer screening behavior.
• To assess the current state of evidence and identify research gaps.

Main Methods:

• A systematic review of published studies was conducted.
• Studies were categorized by design and internal validity.
• Research was rated to assess quality and relevance.

Main Results:

• Forty-two studies met the inclusion criteria for the review.
• Stage-matched mammography interventions demonstrated support, though the literature base is limited.
• Research on the TTM's application to other cancer screenings (e.g., colorectal, cervical) is sparse.

Conclusions:

• The 'stage of change' and 'decisional balance' constructs of the TTM appear applicable to mammography screening behavior.
• Further validation research is essential to confirm the TTM's utility across all cancer screening behaviors.
