Plain English Summary

Background and study aims
Research has shown that people with lung cancer often wait for several months after first noticing symptoms, and this can make it more difficult to treat the disease. This study explores ways in which online information about lung cancer symptoms can be presented to encourage people to see their doctor earlier. Lung cancer patients were interviewed in an earlier study and some of them had used the Internet to look up their symptoms, and this influenced their decision to see their doctor. A website about lung cancer has been designed to encourage people to see their doctor earlier when they have worrying symptoms. This new website uses psychological techniques to influence peoples' beliefs about going to their doctor. The aim of this study is to compare this new website against other versions of the website which don't use these psychological techniques, to see if they have any effect on peoples' intention to make an appointment to have their symptoms checked.

Who can participate?
Patients aged over 18 with possible lung cancer symptoms (e.g., long-standing cough, feeling out of breath, discomfort in the chest, shoulder or back)

What does the study involve?
Participants are randomly allocated to one of four groups, to receive information about lung cancer that is either tailored to individual users (based on their age, smoking and reported symptoms) or not, and that either includes components based on psychological techniques or does not.
Intervention Group: Information is tailored and includes psychological components
Control Group 1: Information is untailored and includes psychological components
Control Group 2: Information is tailored and does not include psychological components
Control Group 3: Information is untailored and does not includes psychological components
All participants are followed up 3 weeks later to assess their intention to seek medical help.

What are the possible benefits and risks of participating?
It is not known whether the study will help the participants but they may find the information provided on the website useful in deciding whether to see a GP about their symptoms. It is not the aim to ask any questions or provide any information that might be upsetting or stressful, but some participants may feel worried about lung cancer after viewing information on our website.

Scientific title

Evaluation of a Web-based intervention to encourage early help-seeking in people with symptoms indicative of lung cancer: a randomised controlled trial


Study hypothesis

The aim of the study is to determine whether information tailoring, and addition of theory-based components to information about lung cancer impacts on individuals' intention to seek medical help.

Lung cancer


The intervention consists of information about lung cancer symptoms, risk factors and a recommendation of when medical advice should be sought. The information is tailored to individual users (based on their age, smoking status and reported symptoms) and also includes components based on psychological theory, to target beliefs people hold about help-seeking. Thus this intervention involves two factors: information tailoring and presence of theory-based components. It is designed to encourage help-seeking for potential lung cancer symptoms.

Participants are randomised to the four study groups using a block randomisation procedure (in blocks of two):
Intervention Group: Information is tailored, and includes theory-based components
Control Group 1: Information is untailored, and includes theory-based components
Control Group 2: Information is tailored, and does not include theory-based components
Control Group 3: Information is untailored, and does not includes theory-based components

For each study group, the intervention duration is approximately 15 minutes. All participants are followed up 3 weeks after the intervention.

Intervention type



Drug names

Primary outcome measure

1. Intention to seek medical help, measured on an 11-point scale at baseline pre-treatment and immediately post-treatment, and, if applicable, at 3 week follow-up. Intention will not be measured again at follow-up if participants report already having sought help at this point
2. Reported help-seeking, measured by asking participants whether they have discussed their symptoms with a health professional (yes/no) at 3-week follow-up

Secondary outcome measures

1. Beliefs and attitudes towards help-seeking, measured using Theory of Planned Behaviour questionnaire at baseline, post-treatment
2. Cancer risk perception, measured using a single item with a 7-point scale at baseline, post-treatment
