Rhinoconjunctivitis Clinical Trial
Official title:
A Motivation-enhancing Intervention to Retain Participants in a Trial After Treatment With Allergen Immunotherapy
The motivation-enhancing intervention is designed for participants in the ILIT.NU trial. The participants are patients with hay fever who are treated with a vaccination in an inguinal lymph node. The motivation-enhancing intervention is a web-based app developed in collaboration with patient partners and is intended to increase retention and reporting in the ILIT.NU trial.
The ILIT.NU trial (EudraCT 2020-001060-28) investigates whether patient reported outcome measures compound symptom-medication score (cSMS) are relieved by intralymphatic immunotherapy (ILIT). The participants are asked for a three-year period to attend annual consultations and to daily fill in an online questionnaire about their allergy symptoms and medication use during the grass pollen season (100 days). High attrition rates have been a problem in previous ILIT trials. High attrition affects generalizability, validity and reliability of a trial. To increase retention and reporting in the ILIT.NU trial, a motivation-enhancing web-based app has been developed. The web app is based on the Self-Determination Theory and is developed in collaboration with patient partners and clinicians. Participants are randomized across treatment group to either the motivation-enhancing web app or the standard reporting method. The project is conducted as a Study Within a Trial (SWAT). ;
