- NCT05016570
- Lead Sponsor
- University of Glasgow
- Brief Summary
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
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.

Group Intervention Description Picture narrative lung screening information Picture narrative information format 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. Text-only lung screening information Text-only information format Participants in this arm receive information about lung screening purpose, eligibility, benefits and risks in a format that uses text and no pictures. Text with pictures lung screening information Text with pictures information format 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.
- Primary Outcome Measures
Name Time Method Lung Cancer Screening Eligibility self-assessment Immediately post-intervention Concordance between self-reported personal eligibility for lung cancer screening and actual eligibility based on self-reported age and smoking behaviour.
Participant Lung Cancer Screening Attitudes Immediately post-intervention Self-administered four-item lung cancer screening attitudes measure covering cancer fear, fatalism, benefits, and worry, previously used by Smits et al 2018.
Participant Lung Cancer Screening Knowledge scores Immediately post-intervention Participants will be asked 6 multiple choice questions related to the lung screening information presented to the participants during the intervention, covering; Procedure, Eligibility - who, Eligibility - why, Benefits, Adverse effects, Potential results.
- Secondary Outcome Measures
Name Time Method Participant Design appraisal ratings Immediately post-intervention Self-administered nine-item measure rating perceptions of appeal, enjoyment, interest, ease of use, trustworthiness, appropriateness, helpfulness, informativity.
Alongside a single item asking participants whether enough information was provided.
