Paper-based and web-based intervention modeling experiments identified the same predictors of general practitioners'...

Area of Science:

• Behavioral Science
• Health Psychology
• Medical Education

Background:

• Developing effective behavioral change interventions is crucial for public health.
• The intervention modeling experiment (IME) offers a framework for pre-trial development and testing.
• Replicating previous studies is essential to validate methodologies.

Purpose of the Study:

• To assess the reliability of the intervention modeling experiment (IME) methodology.
• To confirm the robustness of IME by replicating a prior paper-based study.
• To evaluate IME's utility in developing and testing behavioral change interventions prior to large-scale trials.

Main Methods:

• A web-based questionnaire and clinical scenario study was conducted.
• General practitioners in Scotland participated, completing questionnaires and scenarios.
• Predictors of antibiotic prescribing behavior were identified and compared to a previous paper-based IME.

Main Results:

• 270 general practitioners completed the study.
• Attitude, perceived behavioral control, risk perception, and self-efficacy predicted simulated behavior and intention, matching prior IME findings.
• Persuasive communication was confirmed as an intervention strategy, and an action plan was developed.

Conclusions:

• The web-based intervention modeling experiment (IME) successfully replicated findings from a paper-based IME.
• This replication provides strong support for the validity and robustness of the IME methodology.
• The developed interventions will proceed to a web-based randomized controlled trial for further evaluation.
