Using Think-Aloud methodology and protocol analysis in mammographic practice research

Area of Science:

• Medical Imaging
• Radiography
• Qualitative Research Methods

Background:

• The Think-Aloud method is a qualitative research technique generating verbal protocols from participants.
• It captures real-time decision-making processes during task performance.
• This methodology is valuable for understanding complex cognitive tasks.

Purpose of the Study:

• To discuss the Think-Aloud methodology in the context of radiographer image quality decision-making.
• To explore its application in a simulated environment for evaluating mammographic image quality (MIQ).

Main Methods:

• Describes concurrent and retrospective verbalizations and a three-stage analysis of verbal protocols.
• Utilizes a PhD research case study on radiographer decision-making for MIQ evaluation.
• Focuses on clinical reasoning and strategies in mammographic positioning.

Main Results:

• Presents a synopsis of the MIQ Think-Aloud methodology.
• Includes decision-making rationality theories, a verbal protocol analysis model, and a three-stage MIQ decision-making framework.

Conclusions:

• Concurrent and retrospective verbalizations with three-stage analysis provide a robust method for studying radiographers' image quality decision-making.
• The Think-Aloud Methodology is transferable to other radiography research areas.
• It offers insights into the real-time decision-making complexities faced by radiographers.
