Summary

Understanding health behavior change is key for effective interventions. This study identified common determinants for advancing through the Transtheoretical Model stages, though earlier stages showed less consensus.

Area of Science:

  • Health Psychology
  • Behavioral Science
  • Public Health

Background:

  • Effective health behavior change interventions require understanding the factors that influence transitions between stages.
  • The Transtheoretical Model (TTM) provides a framework for understanding behavior change, but stage-specific determinants need further elucidation.

Purpose of the Study:

  • To identify and reach consensus on determinants facilitating forward transitions between the stages of change within the Transtheoretical Model.
  • To explore stage-specificity of these determinants.

Main Methods:

  • A three-round Delphi study was conducted with experts in stages of change research.
  • Expert opinions on determinants for each stage transition were collected and refined through iterative questionnaires.

  • Consensus was measured based on participant ratings and feedback.

    • Main Results:

    • Participants reached agreement on several determinants influencing stage transitions, such as control-related issues and social support.
    • These determinants were often relevant across multiple transitions, not exclusively stage-specific (e.g., contemplation to maintenance).
    • Consensus was lower for determinants of earlier stage transitions compared to later ones.

    Conclusions:

    • The study identified key hypotheses regarding stage transition determinants for future research.
    • Findings highlight the need for interventions that consider both general and potentially stage-specific factors in behavior change.
    • Further longitudinal and experimental studies are recommended to validate these findings.
