Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test whether a picture narrative format is more successful, than text with pictures or text alone, in communicating lung screening information (primarily defined by positive attitudes towards the design and increase in knowledge) to people likely to be invited to lung screening where available.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Population screening is key to detecting lung cancer early at a more treatable stage. Uptake of screening should be equitable (i.e., screening benefits all eligible members of the population and does not contribute further to health disparities) and informed (i.e., participants have been involved in the decision to take part and their decision aligns with their values and circumstances). Print decision support materials are the primary mechanism for encouraging engagement with cancer screening and supporting decision making. It is essential that we identify print communication techniques that are effective in informing invitees about lung screening.

The intervention, picture narrative information about lung screening, was previously developed through codesign and prototype testing with people likely to be eligible for lung screening (50 to 75 years old, past or current heavy smokers). Participants will be randomised to one of three groups: Picture narrative format, Text with pictures (control 1) or, Text-only (control 2). This study will assess whether presenting lung screening information in a picture narrative format can improve lung cancer screening knowledge, eligibility self-assessment and attitudes. It will also assess whether perceptions of the information designs can explain any impact of the intervention on these outcomes and whether there are differences across socioeconomic groups.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants are randomly assigned to one of three groups. They will receive the same lung screening information but the format of this information will be determined by which group they have been randomised to. All participants will complete a questionnaire immediately after viewing the lung screening information.
Primary Study Purpose

HEALTH_SERVICES_RESEARCH

Blinding Strategy

SINGLE

Investigators
The investigators will be blind to intervention allocation because the intervention and questionnaire is to be undertaken independently and remotely by the participants. Although the intervention is not masked from participants, they will not be informed of the purpose of the study or the different conditions until after they have completed all study measures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Picture narrative lung screening information

Participants in this arm receive information about lung screening purpose, eligibility, benefits and risks in a format which uses text in combination with sequences of pictures to communicate a coherent message. The designs follow conventions from comics/graphic narratives and key stakeholders were involved during the design process.

Group Type EXPERIMENTAL

Picture narrative information format

Intervention Type BEHAVIORAL

Lung screening information formatted as picture narratives

Text with pictures lung screening information

Participants in this arm receive information about lung screening purpose, eligibility, benefits and risks in a format that uses text with non-narrative pictures for decoration. The pictures have been extracted from the picture narratives being used Arm 1.

Group Type ACTIVE_COMPARATOR

Text with pictures information format

Intervention Type BEHAVIORAL

Lung screening information formatted as text and non-narrative pictures

Text-only lung screening information

Participants in this arm receive information about lung screening purpose, eligibility, benefits and risks in a format that uses text and no pictures.

Group Type ACTIVE_COMPARATOR

Text-only information format

Intervention Type BEHAVIORAL

Lung screening information formatted as text with no pictures
